When the latch hook 120 is pressed down on the latch body 112, the latching pin 1311 drives the ball 1312 to move in the upper latch body 1121, so that the ball 1312 moves into the latching groove 121, and at the same time, the relief groove 1321 is far away from the latching pin 1311, the latching pin 1311 abuts against the outer wall of the unlocking member 132, and the movement of the latching pin 1311 is limited, so that the ball 1312 is clamped in the latching groove 121. Alternatively, the unlocking member 132 may be an eccentric structure such as a cam.

In one embodiment, the locking assembly 130 further includes a locking elastic member 133 disposed in the lock body assembly 110, the locking elastic member 133 is sleeved on the locking member 131, one end of the locking elastic member 133 abuts against the lock body assembly 110, and the other end abuts against the locking member 131, and the elastic force of the locking elastic member 133 can keep the locking member 131 in the locking groove 121. Alternatively, the locking elastic member 133 is a spring or other elastic member such as a bellows or the like.

Referring to fig. 2 and 5, when the intelligent padlock 100 is in a locked state, the elastic force of the locking elastic member 133 may cause one end of the locking member 131 to be located in the locking groove 121 and the other end to abut against the outer wall of the unlocking member 132. Referring to fig. 6, 9, 11 and 14, when the unlocking member 132 rotates to align the relief slot 1321 with the latch member 131, the other end of the latch member 131 is no longer restrained by the outer wall of the unlocking member 132 and can move in the upper lock body 1121, and at this time, the force of the upward movement of the latch hook 120 can move the end of the latch member 131 out of the latch slot 121, and the latch member 131 compresses the latch elastic member 133 during the moving process. After the end of the locking member 131 is completely moved out of the locking slot 121, the end of the locking member 131 is always abutted against the outer wall of the locking hook 120 under the elastic force of the locking elastic member 133, and the other end of the locking member 131 is moved into the receding slot 1321, so that the locking hook 120 is unlocked. Referring to fig. 2 and 5 again, after the latch hook 120 is pressed down and the latching groove 121 of the latch hook 120 is aligned with the latching member 131, one end of the latching member 131 moves into the latching groove 121 by the elastic force of the latching elastic member 133 while the other end of the latching member 131 moves out of the relief groove 1321, and then the latching member 132 rotates to make the relief groove 1321 away from the latching member 131, and the other end of the latching member 131 abuts against the outer wall of the latching member 132 to restrict the movement of the latching member 131 in the lock body 112, so that the latching member 131 latches the latch hook 120.

Referring to fig. 1, 2, 6 and 11, in an embodiment, the smart padlock 100 further includes a shackle elastic member 170 disposed in the lock body assembly 110, one end of the shackle elastic member 170 abuts against the lock body assembly 110, and the other end abuts against an end of the shackle 120, and an elastic force of the shackle elastic member 170 may move the other end of the shackle 120 out of the lock body assembly 110. Latch hook spring 170 may provide an upward force to latch hook 120 such that latch hook 120 may automatically move upward under the force of latch hook spring 170 after unlocking member 132 unlocks lockout member 131. Alternatively, the latch hook elastic member 170 is a spring or other elastic member such as a bellows or the like.

The axis of shackle spring 170 coincides with the axis of shackle 120. When the locking hook 120 is locked to the upper locking body 1121, the end of the locking member 131 is positioned in the locking groove 121, and the other end abuts against the outer wall of the unlocking member 132 to restrict the upward movement of the locking hook 120, and at this time, the locking hook 120 compresses the locking hook elastic member 170 since the locking hook 120 cannot move upward. It will be appreciated that the spring force of the latch hook spring 170 is greater than the spring force of the latch spring 133, and the spring force of the latch hook spring 170 will always cause the latch hook 120 to move upward, but the latch member 131 cannot move in the upper latch body 1121 due to the outer wall of the unlocking member 132 stopping the latch member 131. After the unlocking member 132 aligns the receding slot 1321 with the locking member 131, at this time, the locking hook 120 may automatically move upward under the elastic force of the locking hook elastic member 170, the other end of the locking member 131 is no longer limited by the outer wall of the unlocking member 132 and may move in the upper lock body 1121, and at this time, the end of the locking member 131 may move out of the locking slot 121 by the upward moving force of the locking hook 120 until the locking hook elastic member 170 is in the release state, so as to unlock the locking hook 120.

Of course, in other embodiments of the present invention, the latch hook elastic member 170 may not be provided, and the latch hook 120 may be pulled upward directly by an external force.

In one embodiment, the lock body assembly 110 has a first mounting hole along a first direction and a second mounting hole along a second direction, the first direction is perpendicular to the second direction, the locking member 131 is located in the first mounting hole, the unlocking member 132 is located in the second mounting hole, the relief slot 1321 is located on an outer wall of the unlocking member 132, and the relief slot 1321 is a gap of the unlocking member 132. The first direction is the horizontal direction in fig. 2, and the second direction is the vertical direction in fig. 2. The first mounting hole is disposed on the upper locking body 1121 along the horizontal direction, the second mounting hole is disposed on the upper locking body 1121 along the vertical direction, and the first mounting hole is communicated with the second mounting hole. The latch member 131 is movably installed in the first installation hole, and the unlocking member 132 is rotatably installed in the second installation hole. Optionally, the unlocking piece 132 is an unlocking shaft.

The relief groove 1321 is a notch of the unlocking member 132 in the circumferential direction, and the section of the unlocking member 132 where the relief groove 1321 is provided has a D-shape. The horizontal portion of the D-shape is the inner wall of the relief groove 1321, and the arc-shaped portion of the D-shape is the outer wall of the unlocking member 132. When the transmission assembly 140 rotates the unlocking member 132, the position of the relief slot 1321 is changed, so that the relief slot 1321 is aligned with or away from the locking member 131. When the slot 1321 is aligned with the locking member 131, the locking member 131 can move into or out of the slot 1321, and the upper lock member 1121 can move; when the relief slot 1321 is away from the latch member 131, the end of the latch member 131 may abut the outer wall of the unlocking member 132 to limit movement of the latch member 131 in the upper lock body 1121.

Referring to fig. 1, 2, 6 and 11, in one embodiment, the transmission assembly 140 includes a driven gear 141, the driven gear 141 intermittently connects the electrical unlocking assembly 160 and the mechanical unlocking assembly 150, respectively, and one of the electrical unlocking assembly 160 and the mechanical unlocking assembly 150 is intermittently connected to the driven gear 141 and remains stationary while the other is in driving connection with the driven gear 141. The driven gear 141 is used for realizing the transmission of the motion, and the driven gear 141 can be intermittently and drivingly arranged on the mechanical unlocking assembly 150 and can also be intermittently connected with the electrical unlocking assembly 160. When one of the electrical unlocking assembly 160 and the mechanical unlocking assembly 150 operates and controls the driven gear 141 to rotate, the other one of the electrical unlocking assembly 160 and the mechanical unlocking assembly 150 remains in a stationary state. Therefore, the electric unlocking assembly 160 and the mechanical unlocking assembly 150 can be prevented from interfering, and the accurate movement is ensured. Further, the driven gear 141 coincides with the axis of the unlocking member 132, preventing the unlocking member 132 from rotating eccentrically.

In one embodiment, the mechanical unlocking assembly 150 includes a rotating shaft 151 connected to the driven gear 141 and a lock cylinder 152 connected to the rotating shaft 151, wherein the rotating shaft 151 can be intermittently connected to the driven gear 141; rotation of the lock cylinder 152 may rotate the unlocking member 132 via the driven gear 141 to move the locking member 131 into or out of the escape slot 1321. The lock cylinder 152 is the main component for achieving mechanical unlocking. Alternatively, the plug 152 includes, but is not limited to, a mechanical pin plug, but may be other types of plugs. The key cylinder 152 is intermittently connected to the driven gear 141 by a rotating shaft 151.

After the electrical unlocking assembly 160 receives the communication of the electrical unlocking device, the electrical unlocking assembly 160 rotates and drives the driven gear 141 to rotate, and then the driven gear 141 drives the unlocking member 132 to rotate, and meanwhile, the driven gear 141 rotates relative to the rotating shaft 151. When the computer key drives the lock cylinder 152 to rotate, the lock cylinder 152 can drive the rotating shaft 151 to rotate, and then the rotating shaft 151 drives the driven gear 141 to rotate, and the unlocking member 132 rotates to make the receding slot 1321 align with the locking member 131, and meanwhile, the driven gear 141 rotates relative to the electrical unlocking member 160.

Referring to fig. 1, 2, 6 and 11, in an embodiment, the mechanical unlocking assembly 150 further includes a wireless chip 153, and the wireless chip 153 is disposed at an end of the lock cylinder 152 far from the rotating shaft 151 and is used for cooperating with a matching computer key to receive communication of the computer key. The wireless chip 153 is used for storing the identity information of the intelligent padlock 100. The computer key can read the code value of the wireless code chip 153 to determine whether the computer key matches the smart padlock 100. If the identity authentication is passed, namely the computer key is matched with the intelligent padlock 100, the computer key can be unlocked; if the identity authentication fails, i.e., the computer key is not matched with the intelligent padlock 100, the computer key cannot perform the unlocking operation. Moreover, after the computer key and the intelligent padlock 100 perform identity authentication and pass, the lock cylinder 152 can be driven to rotate by rotating the computer key, so that unlocking of the intelligent padlock 100 is realized.

Of course, an emergency mechanical unlock key may also be used to unlock the lock cylinder 152. At this time, the identity authentication process of the wireless code chip 153 can be skipped for quickly unlocking the intelligent padlock 100 in an emergency, so that the unlocking time is prevented from being delayed, and the production safety is ensured.

In one embodiment, the electrical unlocking assembly 160 includes a gear motor 161 and a driving gear 162 installed at an output end of the gear motor 161, and the driving gear 162 is engaged with the driven gear 141 to rotate the unlocking member 132. The reduction motor 161 is a power source for electrical unlocking, and drives the driving gear 162 to rotate, and then the driving gear 162 drives the driven gear 141 to rotate, so that the driven gear 141 drives the unlocking member 132 to rotate, and the electrical unlocking assembly 160 transmits the motion to the transmission assembly 140 to control the unlocking member 132 to rotate, so that the locking hook 120 is unlocked. Of course, in other embodiments of the present invention, the reduction motor 161 may be replaced by other rotatable power sources.

The drive gear 162 and the driven gear 141 are both incomplete gears. When the unlocking is performed electrically, the unlocking member 132 can be driven to rotate when the driving gear 162 is meshed with the driven gear 141; when the driving gear 162 is no longer engaged with the driven gear 141, the driving gear 162 cannot drive the driven gear 141 to rotate, and the rotation angle of the driven gear 141 can be limited. When the mechanical unlocking is performed, the driving gear 162 and the driven gear 141 are not engaged with each other, and the driving gear 162 and the driven gear 141 are intermittently connected to each other.

In one embodiment, the driving gear 162 has at least one driving engaging portion 1621 on an outer circumference thereof, the driven gear 141 has a driven engaging portion 1411 on an outer circumference thereof, and the driving engaging portion 1621 and the driven engaging portion 1411 are engaged with each other. Further, since the driving gear 162 and the driven gear 141 are incomplete gears, the length of the driving meshing portion 1621 in the circumferential direction is smaller than the circumferential length of the driving gear 162, and the length of the driven meshing portion 1411 in the circumferential direction is smaller than the circumferential length of the driven gear 141. The driving engagement portion 1621 and the driven engagement portion 1411 each have a plurality of gear teeth.

As shown in fig. 6 and 10, the driving gear 162 is engaged with the driven engaging portion 1411 of the driven gear 141 through the driving engaging portion 1621 to transmit the motion. It can be understood that the driving engaging portion 1621 and the driven engaging portion 1411 are a plurality of gear teeth, and the transmission is realized by the engagement of the plurality of gear teeth. The driving gear 162 has at least one driving engaging portion 1621 having a circumferential length smaller than a circumferential length of the driving gear 162, that is, the driving gear 162 is not completely toothed. Thus, when the driving gear 162 contacts the driven gear 141 except the driving engaging portion 1621, the driving gear 162 and the driven gear 141 do not rotate synchronously, and the driving gear 162 and the driven gear 141 are indirectly connected, i.e., the intermittent connection between the electrical unlocking assembly 160 and the transmission assembly 140 is realized. Thus, when the mechanical unlocking assembly 150 drives the driven gear 141 to rotate, the driven gear 141 does not drive the driving gear 162 to move due to the intermittent connection between the driven gear 141 and the driving gear 162, and thus the interference between the driving gear 162 and the reduction motor 161 is avoided.

Of course, the circumferential length of the driven meshing portion 1411 of the driven gear 141 is also smaller than the bearing of the driven gear 141, that is, the driven gear 141 is also an incomplete tooth. Thus, after the driving gear 162 drives the driven gear 141 to rotate by a predetermined angle through the driving engaging portion 1621 and the driven engaging portion 1411, the driving engaging portion 1621 and the driven engaging portion 1411 are separated from each other, and at this time, the driving gear 162 is not connected to the driven gear 141, and the driving gear 162 cannot drive the driven gear 141 to rotate continuously. In addition, in the process that the driving gear 162 drives the driven gear 141 to move, the driven gear 141 drives the unlocking member 132 to rotate, so that the receding slot 1321 of the unlocking member 132 aligns with the locking member 131, when the driving engaging portion 1621 is separated from the driven engaging portion 1411, the receding slot 1321 can be kept at the position aligning with the locking member 131, so that the locking member 131 can be accurately moved into the receding slot 1321, and the locking hook 120 is unlocked.

When the latch hook 120 is locked and the blocking member 131 moves out of the relief groove 1321, the driven gear 141 rotates in the opposite direction to reset the unlocking member 132, so as to ensure that the relief groove 1321 moves away from the blocking member 131. The opposite direction here refers to a direction in which the relief groove 1321 is aligned with the latch member 131 when the driven gear 141 rotates.

In one embodiment, the driving gear 162 has two driving engaging portions 1621 on the outer circumference thereof, the two driving engaging portions 1621 are symmetrically arranged, and the two driving engaging portions 1621 are respectively engageable with the driven engaging portions 1411. The two driving engagement portions 1621 are symmetrically arranged, so that the idle time of the speed reduction motor 161 can be reduced, and the waiting time of an operator can be reduced. When the engagement between one of the driving engaging portions 1621 and the driven engaging portion 1411 is completed, the rotation of the reduction motor 161 is stopped, and at this time, there is no connection between the driving gear 162 and the driven gear 141. When the smart padlock 100 is unlocked next time, the reduction motor 161 rotates and drives the driving gear 162 to engage with the driven engaging portion 1411 through another driving engaging portion 1621, so as to reduce the idle time of the reduction motor 161. Meanwhile, the two driving engagement portions 1621 are symmetrically arranged, so that the driving gear 162 can be prevented from driving the driven gear 141 to rotate due to the fact that the speed reduction motor 161 stops accurately, and thus, even if the speed reduction motor 161 rotates after the driving engagement portion 1621 and the driven engagement portion 1411 are engaged, the driving engagement portion 1621 cannot be engaged with the driven engagement portion 1411 due to a certain distance between the two driving engagement portions 1621 and the driven engagement portion 1411.

Referring to fig. 1, 2 to 4, 6 to 8, and 11 to 13, in an embodiment, an end surface of the driven gear 141 facing the unlocking member 132 has a driving portion 1412, and the driving portion 1412 may be in driving connection with the unlocking member 132 to rotate the unlocking member 132. The end surface of the driven gear 141 facing the key cylinder 152 is provided with a first limit portion 1413, the lock body assembly 110 is provided with a first limit groove 11221 for rotatably mounting the first limit portion 1413, and the inner wall of the first limit groove 11221 can intermittently contact with the first limit portion 1413 to limit the rotation angle of the driven gear 141.

The driving portion 1412 may connect the driven gear 141 and the unlocking member 132, such that the driven gear 141 rotates to drive the unlocking member 132 to rotate synchronously, so that the relief slot 1321 of the unlocking member 132 is aligned with or away from the blocking member 131. The lower lock body 1122 has a first limiting groove 11221, and the first limiting groove 11221 can rotatably mount a first limiting portion 1413. Moreover, after the first position-limiting portion 1413 rotates in the first position-limiting groove 11221 by a certain angle, the first position-limiting portion 1413 abuts against an inner wall of the first position-limiting groove 11221 to limit the rotation angle of the first position-limiting portion 1413, and further limit the rotation angle of the driven gear 141, so that the driven gear 141 can only rotate within a certain angle range. This prevents the driven gear 141 from rotating over the stroke, so that the driven gear 141 can accurately drive the unlocking member 132 to rotate, the slot 1321 of the unlocking member 132 can be accurately aligned with the locking member 131, and the slot 1321 can be prevented from rotating over the locking member 131.

Alternatively, the first limit portion 1413 is a segment, and correspondingly, the first limit groove 11221 is a segment matched with the first limit portion 1413. When the radial side wall of the sector abuts against the radial side wall of the sector groove, the sector cannot rotate, indicating that the driven gear 141 is moved in place. Further, the number of the first limiting portions 1413 and the number of the first limiting grooves 11221 are two, and the two first limiting portions 1413 are symmetrically arranged and respectively correspond to the two first limiting grooves 11221, so that the driven gear 141 is accurately limited.

As shown in fig. 2, 3, 6, 7, 11 and 12, in an embodiment, the rotating shaft 151 has a protrusion 1511 extending toward the first limit portion 1413, and the protrusion 1511 may be intermittently connected to the first limit portion 1413 for keeping the lock cylinder 152 stationary when the driving gear 162 drives the driven gear 141 to rotate. When the driving gear 162 is stationary, the protrusion 1511 may abut against the first stopper 1412 and drive the driven gear 141 to rotate.

The protrusion 1511 may protrude into the hollow portion of the driven gear 141 and be located at a side of the first stopper 1413. When the driving gear 162 drives the driven gear 141 to rotate, the first position-limiting portion 1413 can rotate in the first position-limiting groove 11221, but the first position-limiting portion 1413 moves in a direction away from the protrusion 1511, so that the driven gear 141 and the rotating shaft 151 are intermittently connected, and the driven gear 141 is prevented from driving the rotating shaft 151 and the lock cylinder 152 to rotate during electrical unlocking. When the lock cylinder 152 drives the rotating shaft 151 to rotate, the rotating shaft 151 abuts against the first limiting portion 1413 when rotating, and then drives the driven gear 141 to rotate, so that the first limiting portion 1413 rotates in the first limiting groove 11221, however, since the speed reduction motor 161 does not rotate, at this time, the driving gear 162 corresponds to a portion of the driven gear 141 without an engaging portion, that is, there is no connection relationship, so that the intermittent connection between the driving gear 162 and the driven gear 141 is realized, and the driven gear 141 is prevented from driving the driving gear 162 to rotate during mechanical unlocking.

As shown in fig. 2 and 3, when the intelligent padlock 100 is in the locked state, the protrusion 1511 is located clockwise of the first stopper 1413. Because one edge of the first limiting portion 1413 is tightly attached to the radial inner wall of the first limiting groove 11221, the unlocking member 132 can be driven to rotate only by the counterclockwise rotation of the first limiting portion 1413 of the driven gear 141 in the first limiting groove 11221, so as to unlock the intelligent padlock 100, no matter mechanical unlocking or electrical unlocking is performed. As shown in fig. 6 and 7, during the electrical unlocking, the driving gear 162 drives the driven gear 141 to rotate, so that the first limiting portion 1413 rotates counterclockwise in the first limiting groove 11221, and at this time, the driven gear 141 can drive the unlocking member 132 to rotate, so that the receding groove 1321 of the unlocking member 132 aligns with the locking member 131, and the locking hook 120 is unlocked. As shown in fig. 11 and 12, during mechanical unlocking, the lock cylinder 152 drives the rotating shaft 151 to rotate counterclockwise, and then the protrusion 1511 of the rotating shaft 151 abuts against the sidewall of the first limiting portion 1413 when rotating counterclockwise, so as to drive the first limiting portion 1413 to rotate counterclockwise in the first limiting groove 11221, at this time, the driven gear 141 can drive the unlocking member 132 to rotate, so that the receding groove 1321 of the unlocking member 132 aligns with the locking member 131, and unlocking of the locking hook 120 is achieved.

As shown in fig. 1, 5, 9 and 14, in an embodiment, the end of the driven gear 141 facing the unlocking member 132 further has an engaging portion 1414, the transmission assembly 140 further includes a twisting member 142, the twisting member 142 is sleeved on the driving portion 1412, one end of the twisting member 142 abuts against the lock body assembly 110, and the other end of the twisting member 142 is engaged with the engaging portion 1414, the twisting force of the twisting member 142 can make the driven gear 141 drive the unlocking member 132 to rotate, so that the outer wall of the unlocking member 132 stops the locking member 131. The twister 142 can effect the reset of the driven gear 141. When the twister 142 is in the released state, the smart padlock 100 is in the locked state. The twisting member 142 is compressible under the action of external force, and when the external force disappears, the twisting member 142 can be reset. Alternatively, the number of the catching portions 1414 may be plural to adjust the twisting force of the twisting member 142. Alternatively, the torsion member 142 is a torsion spring, a coil spring, or the like.

When unlocking, the driven gear 141 compresses the twisting member 142 under the driving force of the driving gear 162 or the rotating shaft 151, so that the driven gear 141 drives the unlocking member 132 to rotate, and the receding slot 1321 aligns with the locking member 131. Since the locking member 131 is aligned with the end of the offset slot 1321 without stopping the outer wall of the unlocking member 132, the locking hook 120 can move upward under the elastic force of the locking hook elastic member 170, so that the locking member 131 moves in the upper lock body 1121, and during the movement of the locking member 131, one end gradually moves out of the locking slot 121, and the other end gradually moves into the offset slot 1321. After unlocking is completed, one end of the latch member 131 abuts against the outer wall of the lock hook 120, and movement of the latch member 131 is restricted. Because the locking member 131 is clamped in the receding slot 1321, the rotation of the unlocking member 132 is limited, and the twisting force of the twisting member 142 cannot drive the unlocking member 132 to rotate, so that the unlocking of the intelligent padlock 100 is realized.

When latching, the latch hook 120 is pressed downward such that the latch hook 120 compresses the latch hook elastic member 170, and at this time, the latch member 131 is aligned with the latch groove 121, and one end of the latch member 131 is movable into the latch groove 121 by the elastic force of the latch elastic member 133, and accordingly, the other end of the latch member 131 is movable out of the escape groove 1321. Meanwhile, since the locking member 131 is no longer locked in the receding groove 1321, the twisting member 142 loses the external force effect, and the driven gear 141 and the unlocking member 132 can be driven to reset under the twisting force effect, so that the receding groove 1321 of the unlocking member 132 is far away from the locking member 131. After the twisting member 142 enables the driven gear 141 to drive the unlocking member 132 to reset, the first limiting portion 1413 can be ensured to reciprocate in the first limiting groove 11221, so that the first limiting portion 1413 is conveniently matched with the extending portion 1511, and the driven engaging portion 1411 is also conveniently engaged with the driving engaging portion 1621.

Referring to fig. 2, 4, 6, 8, 11 and 13, in an embodiment, the rotating shaft 151 has a second limiting portion 1512, the second limiting portion 1512 is located at an outer periphery of an end of the rotating shaft 151 connected to the lock cylinder 152, the lock body assembly 110 further has a second limiting groove 11222 rotatably mounted on the second limiting portion 1512, and an inner wall of the second limiting groove 11222 may intermittently contact with the second limiting portion 1512 to limit a rotation angle of the driven gear 141. The lower locking body 1122 further has a second limiting groove 11222, and the cooperation between the second limiting portion 1512 and the second limiting groove 11222 can further limit the rotation angle of the rotating shaft 151, so that the rotating shaft 151 can only rotate within a certain angle range.

Alternatively, the second limiting portion 1512 is a protrusion, and correspondingly, the second limiting groove 11222 is a sector-shaped groove matched with the second limiting portion 1512, and the protrusion can rotate in the sector-shaped groove. When the radial side wall of the projection abuts against the radial side wall of the sector groove, the projection cannot rotate, indicating that the driven gear 141 is moved in place. Furthermore, the number of the second limiting parts 1512 and the number of the second limiting grooves 11222 are two, and the two second limiting parts 1512 are symmetrically arranged and respectively correspond to the two second limiting grooves 11222, so that accurate limiting of the driven gear 141 is ensured.

As shown in fig. 2 and 3, when the intelligent padlock 100 is in a locked state, one edge of the second limiting portion 1512 is tightly attached to the radial inner wall of the second limiting groove 11222, and the second limiting portion 1512 can rotate counterclockwise in the second limiting groove 11222, so as to unlock the intelligent padlock 100. During the electrical unlocking, the driving gear 162 drives the driven gear 141 to rotate, the driven gear 141 is intermittently connected to the rotating shaft 151, that is, the rotating shaft 151 keeps a stationary state, and further, the position of the second limiting portion 1512 in the second limiting groove 11222 remains unchanged, as shown in fig. 6 and 8.
