As shown in fig. 1-3 and 5, a protrusion 1131 is disposed at an end of the receiving groove 113 adjacent to the notch 114, a vertical guiding plane 1132 and a side wall 1133 are formed at an upper end of the protrusion 1131, and the guiding plane 1132 is horizontally disposed, that is, the guiding plane 1132 is perpendicular to the moving direction of the pressing handle 120, and the side wall 1133 is parallel to the moving direction of the pressing handle 120. In addition, a fixing wall 1134 is disposed at the other end of the accommodating groove 113, that is, the fixing wall 1134 and the boss 1131 are disposed at two ends of the accommodating groove 113 in the X-axis direction, the fixing wall 1134 and the partition 111 are disposed at intervals, and an inverted buckle 1135 is further disposed on the fixing wall 1134. The elastic member 150 is accommodated in the accommodating groove 113, and one end of the elastic member 150 is fixed to the inverse buckle 1135 so that the elastic member cannot fall out, and the inverse buckle 1135 causes the elastic member to generate a torque, and the other end of the elastic member 150 is located above the guide plane 1132, specifically, suspended above the guide plane 1132, when the elastic member 150 is subjected to the acting force of the driving member 140, the elastic member 150 can move downward by a small distance to abut against the guide plane 1132, and at this time, the elastic member 150 is limited to only swing transversely.

Furthermore, the partition 111 further has a stop block 1126 protruding from the partition 111, the stop block 1126 is disposed at a position close to the notch 114 and protrudes into the receiving groove 113, and the position of the stop block 1126 is higher than the position of the guide plane 1132 in the vertical direction, that is, the stop block 1126 and the guide plane 1132 have a height difference in the vertical direction, the elastic arm 152 (described in detail later) of the elastic member 150 is inserted between the stop block 1126 and the guide plane 1132, and when the elastic member 150 is in the initial state, the elastic arm 152 abuts against the stop block 1126, but the end 1521 of the elastic arm 152 is suspended above the guide plane 1132, as shown in fig. 3 and 5.

With reference to fig. 1-3 and 5, in the present invention, the elastic member 150 includes a fixing portion 151 and an elastic arm 152 protruding from the fixing portion 151, the elastic member 150 is accommodated in the accommodating groove 113 and fixes the fixing portion 151 on the inverse buckle 1135, which can prevent the elastic member 150 from falling out and generate a large torque, the elastic arm 152 extends along the X-axis direction, and an end portion 1521 of the elastic arm 152 far from the fixing portion 151 is suspended above the guide plane 1132, and since the pressing handle 120 moves along the vertical direction (Z-axis direction), the protruding direction of the elastic arm 152 intersects with the moving direction of the pressing handle 120. In the present invention, the elastic arm 152 preferably protrudes in a direction perpendicular to the moving direction of the pressing handle 120.

As shown in fig. 3 and 5, the driving member 140 acts on the elastic arm 152 through the notch 114. When the pressing handle 120 is at the initial position, the end portion 1521 of the elastic arm 152 is suspended above the guide plane 1132, and the elastic arm 152 is vertically limited by the limit block 1126. When the pressing handle 120 moves downwards, the driving member 140 pushes the elastic arm 152 to move downwards for a small distance, and then the end portion 1521 of the elastic arm 152 abuts against the guide plane 1132, and the elastic arm 152 is limited by the limiting block 1126 and the guide plane 1132, so that the elastic arm 152 can only swing transversely when being continuously stressed, that is, the elastic arm 152 swings along the Y-axis direction and is away from the pressing handle 120, and the end portion 1521 of the elastic arm 152 moves along the guide plane 1132. When the elastic arm 152 is disengaged from the driving member 140 and loses its acting force, the elastic arm 152 recovers its deformation and swings laterally under its own elastic force to return to its original position, i.e., moves in the negative direction of the Y-axis to return to its original position, and the end portion 1521 of the elastic arm 152 is again disengaged from the guide plane 1132 and suspended above the guide plane 1132. In the above process, the elastic arm 152 does not generate a pressing distance, so the elastic arm 152 does not generate a rebound impact, and therefore, no impact sound or only a negligible minimum sound is generated, so that the elastic segment shaft body 100 mainly presents a segment hand feeling and has a strong vibration hand feeling.

In the utility model, the elastic part 150 is preferably a torsion spring, the torsion spring is mature in technology, the elasticity is easy to control, and the torsion spring can generate larger elastic force, thereby ensuring strong vibration hand feeling and impact sound, and ensuring the synchronization of conduction, sound production and vibration hand feeling. Of course, the elastic element 150 is not limited to a torsion spring, and other elastic elements, such as a metal spring, may be used to implement the present invention.

As shown in fig. 1-3 and fig. 6, the driving member 140 is convexly disposed on the side wall 124 of the pressing handle 120 adjacent to the elastic member 150, the driving member 140 has a driving inclined surface 141 and a guiding inclined surface 142 disposed at an included angle, the guiding inclined surface 142 is disposed above the driving inclined surface 141, a connection position between the driving inclined surface 141 and the guiding inclined surface 142 is in an arc transition, and a connection position between the driving inclined surface 141 and the guiding inclined surface 142 forms an arc connection portion 143. More specifically, referring to fig. 6, the driving slope 141 extends downward, and a lower end portion of the driving slope 141 is flush with a lower end of the sidewall of the knob 120, the guide slope 142 extends upward obliquely and is connected to the sidewall of the knob 120, and a side surface of the driving member 140 is substantially arc-shaped and convex. In the process that the pressing handle 120 moves up and down, the driving inclined surface 141 and the guiding inclined surface 142 can drive the elastic arm 152 to deform and swing transversely, so that a strong vibration hand feeling is generated.

Referring again to fig. 3 and 5-6, when the pressing handle 120 is in the initial state, the end portion 1521 of the elastic arm 152 is suspended above the guide plane 1132, as shown in fig. 3 and 5. When the pressing handle 120 moves downwards in the direction indicated by the arrow F1 in fig. 6, the driving inclined surface 141 of the driving element 140 acts on the elastic arm 152 to push it to move downwards a small distance, so that the end portion 1521 abuts against the guide plane 1132, and at this time, the elastic arm 152 is limited, so that the driving element 140 can only push the elastic arm 152 to swing transversely away from the pressing handle 120, that is, the elastic arm 152 swings in the Y-axis direction; when the elastic arm 152 passes over the connecting portion 143 and loses the acting force of the driving inclined surface 141, the elastic arm 152 recovers deformation and resets under the action of its own elastic force, in the process, the elastic arm 152 slides along the guiding inclined surface 142 to move towards the pressing handle 120 for resetting, meanwhile, the end portion 1521 of the elastic arm 152 rebounds to the upper side of the guiding plane 1132, and as the elastic arm 152 does not generate a pressing distance in the vertical direction, no rebound impact, no impact sound or only negligible minimal sound is generated, and a step-down hand feeling is generated only when the driving member 140 slides over the elastic arm 152, so that a strong vibration hand feeling is achieved.

As shown in fig. 6, when the pressing handle 120 is moved upward to be reset, i.e., moved in the direction opposite to the direction indicated by the arrow F1 in fig. 6, the guiding inclined surface 142 may act on the elastic arm 152 to swing in the Y-axis direction away from the pressing handle 120, and when the elastic arm 152 passes over the connecting portion 143, the elastic arm 152 is reset and moved to the initial position by its own elastic force, and in this process, only a vibration feeling is generated without generating an impact sound.

In the present invention, the driving member 140 may be integrally formed with the handle 120, or may be separately formed and fixed to a sidewall of the handle 120. The driving member 140 is not limited to the above structure, and may be configured to have other structures to generate different vibration handfeel, for example, the driving inclined plane 141 and the guiding inclined plane 142 are configured to be connected to form an arc structure, and at this time, the side surface of the driving member 140 is configured to be an arc structure, which may also generate vibration handfeel.

Referring to fig. 1-3 and 6, the pressing handle 120 includes a main body 121, a pressing portion 1211 is formed at an upper end of the main body 121, and a guiding post 122 is disposed at a lower end of the main body 121 and is engaged with the bottom hole 1122 of the positioning post 1121. In addition, the latch 123 is protruded from the sidewall of the main body 121, the pressing portion 1211 is protruded from the mounting hole 115 of the upper housing 110a, the pressing handle 120 is movably mounted in the sliding cavity of the housing 110, the sliding of the pressing handle 120 is guided and limited by the sliding fit of the latch 123 and the latch 1124, the guiding post 122 is inserted into the bottom housing hole 1122 of the positioning post 1121, and the upper end of the reset element 130 abuts against the main body 121 of the button 120.

In the present invention, the reset element 130 is preferably a compression spring, and when the reset element 130 is installed, the positioning pillar 1121 is sleeved with the reset element 130, and two ends of the reset element 130 respectively abut against the bottom surfaces 112a of the body 121 and the installation groove 112, so that when the pressing handle 120 is forced to slide downwards against the elastic force of the reset element 130, the reset element 130 is deformed, and when the acting force on the pressing handle 120 disappears, the reset element 130 is deformed again to drive the pressing handle 120 to reset. It should be understood that the position member 130 is not limited to a compression spring, but other elastic elements may be used to reset the pressing handle 120.

The operation of the shaft 100 of the present invention will be described with reference to fig. 1-6.

As shown in fig. 3 and 5, when the pressing handle 120 is at the initial position, the end portion 1521 of the elastic arm 152 is suspended above the guide plane 1132, and the elastic arm 152 is restricted by abutting against the limit block 1126 in the vertical direction.

When the pressing handle 120 is forced to move downwards along the Z-axis direction (the direction indicated by the arrow F1 in fig. 6), the driving inclined surface 141 of the driving member 140 will abut against the elastic arm 152, and during the downward movement of the pressing handle 120, the driving inclined surface 141 will push the elastic arm 152 to move downwards a small distance, so that the end portion 1521 of the elastic arm 152 abuts against the guide plane 1132, and the elastic arm 152 is limited by the limiting block 1126 and the guide plane 1132, so that the elastic arm 152 can only swing transversely when being forced continuously, that is, the elastic arm 152 swings along the Y-axis direction (the direction indicated by the arrow F2 in fig. 6) to be far away from the pressing handle 120, and the elastic arm 152 deforms during the transverse swinging.

When the pressing handle 120 moves down continuously to make the connecting portion 143 of the driving member 140 pass over the elastic arm 152, the elastic arm 152 loses its force and returns to its original shape, and swings back along the guide plane 1132 under its own elastic force, i.e., moves in the negative direction of the Y axis to return to its original shape, and at the same time, the end portion 1521 of the elastic arm 152 is lifted above the guide plane 1132.

In the above process, the elastic arm 152 does not generate a pressing distance, so the elastic arm 152 does not generate a rebound impact, and therefore, no impact sound or only a negligible minimum sound is generated, so that the elastic segment shaft body 100 mainly presents a segment hand feeling and has a strong vibration hand feeling.

During the downward movement of the pressing handle 120, the pressing handle 120 compresses the restoring member 130 to be deformed. When the pressing handle 120 is released, the pressing handle 120 moves upwards to reset under the action of the resetting piece 130, and in the process of moving the pressing handle 120 upwards, the guide inclined surface 142 of the driving piece 140 acts on the elastic arm 152, so that the elastic arm 152 is pushed to swing away from the pressing handle 120 along the Y-axis direction, and only the elastic arm 152 can be pushed to swing transversely; when the handle 120 moves up to the connection part 143 of the driving member 140 and passes over the elastic arm 152, the elastic arm 152 loses its force and returns to its original shape, so that it swings back to the handle 120 under its own elastic force, and no impact sound is generated in the process.

In summary, in the elastic section shaft body 100 of the present invention, the housing 110 is provided with a limit block 1136 and a guide plane 1131, the limit block 1136 and the guide plane 1131 are disposed at intervals in the vertical direction and the horizontal direction, the elastic element 150 extends horizontally and penetrates between the limit block 1136 and the guide plane 1131, and one end of the elastic element 150 is suspended above the guide plane 1131, when the driving member 140 acts on the elastic member 150 during the up-and-down reciprocating movement of the pressing handle 120, the elastic member 150 can only swing back and forth transversely due to the limitation of the limiting block 1136 and the guide plane 1131, therefore, no pressing distance is generated, the elastic member 150 does not rebound and impact, and thus no impact sound or only negligibly little sound is generated, so that the elastic segment shaft body 100 mainly exhibits a segment hand, that is, having a strong vibration feeling but not making a sound, thereby allowing the user to have a different use experience.

The structure of the other parts of the elastic segment shaft 100 according to the present invention is well known to those skilled in the art, and will not be described in detail herein.
