Referring to fig. 1 and 2, a disassembly and assembly tool 100 according to an embodiment of the present disclosure includes a fixed member 10, a movable member 20, and a clamping jaw 30. The moving member 20 is movably disposed on the stationary member 10. The number of the clamping jaws 30 is multiple, each clamping jaw 30 is rotatably arranged on the fixed part 10, a first end 31 of each clamping jaw 30 is movably connected with the moving part 20, in the process that the moving part 20 moves relative to the fixed part 10 along a first direction, second ends 32 of all the clamping jaws 30 are gathered together, in the process that the moving part 20 moves relative to the fixed part 10 along a second direction, the second ends 32 of all the clamping jaws 30 are far away from each other, the first direction is opposite to the second direction, and the first ends 31 and the second ends 32 of the clamping jaws 30 are respectively positioned on two opposite sides of the rotating axis of the clamping jaws 30.

The disassembly and assembly tool 100 of the embodiment of the application can control the clamping jaw 30 to rotate by controlling the movement of the moving member 20. The clamping jaw 30 can rotate within a certain range to replace wrenches with different specifications so as to match different aviation plugs. Therefore, the disassembling and assembling tool 100 can reduce the time for selecting tools in the disassembling and assembling process, improve the production efficiency and reduce the production cost.

Specifically, the fixing member 10 provides a space and a structure for fixing and accommodating the moving member 20 and the clamping jaw 30. Mobile element 20 may be a movable member inside stationary element 10 for moving clamping jaw 30. The jaws 30 may be similar members to a hand grip for gripping a workpiece. The shape of the jaw 30 may be a finger of a human hand, such as a three-finger jaw, a five-finger jaw, or a flat structure without a finger shape, such as a parallel two-sided clamp. The number of the clamping jaws 30 may be plural, for example, the number of the clamping jaws 30 is two in the embodiment of fig. 1.

When the number of the clamping jaws 30 is two, the clamping jaws 30 may be symmetrically disposed inside the fixing member 10. Each jaw 30 may have two ends. The first end 31 of the clamping jaw 30 may be located at the upper portion of the clamping jaw 30, and the first end 31 of the clamping jaw 30 may be connected with the moving member 20. The connection may be a rotatable connection of pin 40 to moveable member 20. First ends 31 of jaws 30 are movable in synchronization with mover 20. The second end 32 of the jaw 30 may be located at a lower portion of the jaw 30, and the second end 32 of the jaw 30 may be rotatably connected to the fixing member 10 by a fixing pin 41. The second end 32 of the jaw 30 may be primarily used to grasp a workpiece. The first end 31 of the jaw 30 and the second end 32 of the jaw 30 may be located on opposite sides of the axis of rotation of the jaw 30. The axis of rotation may coincide with the central axis 90 of the removal tool 100.

The moving member 20 is movable in a first direction (shown in fig. 1) and a second direction (shown in fig. 1) with respect to the stationary member 10. The first direction may be a direction in which an end of the moving member 20 away from the jaws 30 faces away from the jaws 30. The second direction may be a direction in which an end of the moving member 20 away from the jaws 30 faces the jaws 30. As shown in the orientation of fig. 1, the first direction may be a moving direction of the moving member 20 in a vertically upward direction, and the second direction may be a moving direction of the moving member 20 in a vertically downward direction. The first direction and the second direction may be opposite to each other.

When the moving member 20 moves in the first direction relative to the fixed member 10, the second ends 32 of all the clamping jaws 30 can approach the central axis 90 of the disassembling tool 100, i.e. the second ends 32 of all the clamping jaws 30 can gather together. When the moving member 20 moves in the second direction relative to the fixed member 10, the second ends 32 of all the clamping jaws 30 can be deviated towards the central axis 90 of the disassembling tool 100, i.e. the second ends 32 of all the clamping jaws 30 can be spread away from each other.

Referring to fig. 1, in some embodiments, the fixing member 10 has a hollow hole 11, the moving member 20 is inserted into the hollow hole 11, and the clamping jaw 30 at least partially extends out of the hollow hole 11.

In this way, the hollow hole 11 of the fixed part 10 accommodates the moving part 20 and part of the clamping jaw 30, and the moving part 20 and the first end 31 of the clamping jaw 30 can be protected from being interfered by the outside of the fixed part 10.

Specifically, the hollow hole 11 of the fixing member 10 may be a space inside the fixing member 10. The hollow hole 11 may have a space in which the moving member 20 moves in the first and second directions. The hollow bore 11 may receive a portion of the clamping jaw 30, and the portion of the clamping jaw 30 may be an integral half of the clamping jaw 30 from the first end 31 of the clamping jaw 30. Thus, one-half of the jaw 30 to the second end 32 of the jaw 30 may extend out of the hollow bore 11.

Referring to fig. 1 and 2, in some embodiments, the fixing member 10 includes a first sleeve 13 and a second sleeve 14, the first sleeve 13 is connected to one axial end of the second sleeve 14, the first sleeve 13 has a first through hole 111, the second sleeve 14 has a second through hole 112, the first through hole 111 has a smaller diameter than that of the second sleeve 14, the moving member 20 is disposed in the first through hole 111 and the second through hole 112, the clamping jaw 30 at least partially extends out of the first through hole 111, and the hollow hole 11 includes the first through hole 111 and the second through hole 112.

Thus, the first sleeve 13 and the second sleeve 14 define a first through hole 111 and a second through hole 112. The first through hole 111 and the second through hole 112 can provide a receiving position for the moving member 20 and the partial clamping jaw 30. The first through hole 111 and the second through hole 112 can provide a relatively closed space area, and influence on the moving process of the moving member 20 and the rotating process of part of the clamping jaw 30 by the outside of the first through hole 111 and the second through hole 112 is reduced.

Specifically, the first sleeve 13 of the fixing member 10 may be located at a lower portion of the fixing member 10, and the second sleeve 14 of the fixing member 10 may be located at an upper portion of the fixing member 10. The first sleeve 13 and the second sleeve 14 can be connected in a manner that facilitates disassembly. The first sleeve 13 and the second sleeve 14 may be connected by a screw or a snap connection.

The shape structure of the first sleeve 13 can be composed of three-dimensional circular rings with the same inner diameter and different outer diameters. The solid ring on the upper part of the first sleeve 13 may have a threaded structure which may be used to mate with threads on the second sleeve 14. The first sleeve 13 may be a solid ring structure having a middle portion and an outer diameter larger than that of the upper portion of the first sleeve 13. The lower part of the first sleeve 13 may be a three-dimensional ring structure with the smallest outer diameter of the first sleeve 13. The first sleeve 13 may have a first through hole 111, and the first through hole 111 may be formed through a central region of the first sleeve 13. The lower portion of the first sleeve 13 may receive a portion of the clamping jaw 30, and the clamping jaw 30 may extend out of the first sleeve 13 at a second end 32.

The second sleeve 14 may be located above the first sleeve 13 and may be threadably connected to the second sleeve 14. The shape structure of the second sleeve 14 may be a solid circular ring structure. The second through hole 112 of the second sleeve 14 may be penetrated in a central region of the second sleeve 14. The second through hole 112 and the first through hole 111 cooperate to accommodate the moving member 20.

Referring to fig. 1, in some embodiments, the hole wall 1111 of the first through hole 111 limits a degree of freedom of the moving member 20 on a predetermined plane, the predetermined plane being perpendicular to the first direction.

Thus, the hole walls 1111 are disposed to limit the moving direction of the moving member 20 to the first direction and the second direction. Pore wall 1111 can prevent moving member 20 from freely moving along a predetermined plane during moving process, and moving member 20 can be limited inside pore wall 1111.

Specifically, the hole wall 1111 may be a structure forming the first through hole 111. Aperture wall 1111 may have a thickness such that an inner side of aperture wall 1111 may be in direct contact with moving member 20. Aperture wall 1111 may have a fixed position such that the portion of moveable member 20 received within aperture wall 1111 is confined within aperture wall 1111.

Referring to fig. 1, in some embodiments, the clamping jaw 30 is formed with a sliding slot 33, an included angle is formed between a length direction of the sliding slot 33 and a first direction, the clamping jaw 30 is disposed on the moving member 20 through a pin 40, and the pin 40 penetrates through the sliding slot 33 and the moving member 20.

In this way, the moving member 20 is connected to the sliding slot 33 of the clamping jaw 30 through the pin 40, and when the moving member 20 moves in the first direction or the second direction, the sliding slot 33 of the clamping jaw 30 can move in the length direction. The sliding slot 33 moves to move the clamping jaw 30. Thereby, the linear motion of the movable element 20 can be converted into the rotational motion of the gripping jaw 30, and the range of action of the attachment/detachment tool 100 can be changed.

Specifically, the runners 33 of the jaws 30 may be proximate the first ends 31 of the jaws 30. The sliding slot 33 may be a hollow structure on the clamping jaw 30. The shape of the sliding slot 33 may be a long strip with ends connected by a circular arc. Runner 33 of jaw 30 may be pinned to moveable member 20. The pin connection may be a pin shaft 40 connection, and the pin shaft 40 penetrates through the connecting chute 33 and the moving member 20. The slide slots 33 of the jaws 30 are movable along their length, limited by the connection of the pins 40. The length direction of the sliding slot 33 may be at an angle to the first direction.

Referring to fig. 1 and 2, in some embodiments, the disassembling tool 100 further includes an adjusting member 50, the adjusting member 50 is fixed to an end of the moving member 20 away from the clamping jaw 30, and the adjusting member 50 can move relative to the fixing member 10.

So, regulating part 50 sets up can adjust moving member 20 through regulating part 50 in the use on assembly and disassembly tools 100, and then drives clamping jaw 30 activity, enlarges clamping jaw 30's rotation range.

Specifically, the adjusting member 50 may be coupled to an upper portion of the moving member 20 to be movable in first and second directions within the hollow hole 11 of the fixing member 10. The shape of the adjusting member 50 can match the shape of the hollow hole 11 of the fixing member 10, and the adjusting member 50 can move up and down relative to the fixing member 10. That is, the adjusting member 50 may be moved in the second direction by manually pressing the adjusting member 50, or the adjusting member 50 may be moved in the first direction by manually pulling the adjusting member 50.

Referring to fig. 1 and 2, in some embodiments, the disassembling tool 100 further includes an elastic member 60, the elastic member 60 is connected to the adjusting member 50, and the elastic member 60 is elastically deformed during the process that the external force moves the moving member 20 relative to the fixed member 10 in the second direction. After the external force is removed, the elastic member 60 is deformed again and the movable member 20 is moved in the first direction relative to the stationary member 10 by the adjusting member 50.

In this manner, the elastic member 60 can provide elastic feedback to the adjusting member 50, and the elastic member 60 can provide a force for moving the moving member 20 in the first direction. When the moving member 20 drives the clamping jaws 30 to a proper rotation range, the elastic member 60 can restore the moving member 20 to drive the clamping jaws 30 to fold, so as to complete automatic clamping.

Specifically, the elastic member 60 may be an elastic member having an automatic restoring function. The elastic member 60 may be a spring, rubber, or the like. The elastic member 60 used in the embodiment of the present application may be a spring, and similarly, a manual or automatic clamping structure may be used to replace the automatic springback function of the spring, which is not limited herein.

The upper end of the elastic element 60 can be connected to the bottom of the adjusting element 50, when the adjusting element 50 is acted by external force to move in the second direction, the adjusting element 50 can drive the moving element 20, and the moving element 20 can move in the second direction relative to the fixed element 10. The elastic member 60 is elastically deformable by the pressure of the adjusting member 50. When the external force applied to the adjusting member 50 is removed, the elastic member 60 can restore the deformation, and generate an acting force to the adjusting member 50 to move in the first direction, so that the adjusting member 50 can return to the initial position. Therefore, the moving member 20 can move in the first direction by the connection of the adjusting member 50.

Referring to fig. 1 and 2, in some embodiments, the fixing member 10 has a hollow hole 11, the moving member 20 is inserted into the hollow hole 11, the clamping jaw 30 at least partially extends out of the hollow hole 11, the fixing member 10 includes a supporting surface 12 located in the hollow hole 11, one end of the elastic member 60 is connected to the adjusting member 50, and the supporting surface 12 provides support for the other end of the elastic member 60.

In this manner, the support surface 12 remains fixed in position relative to the fixture 10. The support surface 12 can provide the elastic member 60 to support so that when one end of the elastic member 60 connected with the adjusting member 50 moves in the second direction, the other end moves asynchronously. The elastic member 60 may be deformed.

In particular, the support surface 12 may be a top surface of the second sleeve 14, and the support surface 12 may remain fixed within the fixture 10. The support surface 12 may provide support to one end of the spring 60. The plane of the support surface 12 may be perpendicular to the plane of the resilient member 60.

Referring to fig. 1 and 2, in some embodiments, the disassembling tool 100 includes a spacer 70, the spacer 70 is fixed on the supporting surface 12 and aligned with the elastic member 60, and the elastic member 60 abuts against the spacer 70 during the external force moves the moving member 20 relative to the fixed member 10 in the second direction.

In this manner, the pad 70 is secured to the support surface 12 in a stable condition. One end of the elastic element 60 abuts against the gasket 70 to prevent the elastic element 60 from sliding, so that the deformation direction of the elastic element 60 can be consistent with the moving direction of the moving element 20.

In particular, the spacer 70 may be disposed on the support surface 12 and may be fixedly connected to the support base. The upper portion of the gasket 70 may contact one end of the elastic member 60. Naturally, the gasket 70 may be in light contact with the elastic member 60. When the elastic member 60 is compressed, the gasket 70 may be in close contact with the elastic member 60, and may transmit a supporting effect of the supporting surface 12 to one end of the elastic member 60.

Referring to fig. 1 and 2, in some embodiments, the dismounting tool 100 includes an operating member 80, the operating member 80 is fixed to an end of the fixing member 10 away from the clamping jaw 30, and the operating member 80 extends in a transverse direction of the fixing member 10.

In this way, when the clamping jaw 30 of the attaching and detaching tool 100 clamps the corresponding workpiece, the operation member 80 is rotated by applying an external force to drive the entire attaching and detaching tool 100 to rotate, thereby performing operations such as rotation and tightening of the workpiece. The operation member 80 can save labor during use of the assembly and disassembly tool 100.

Specifically, the operating element 80 may be a member that rotates the entire attachment/detachment tool 100. The operating member 80 may be in the shape of a rod-like structure. The operation member 80 may be symmetrically disposed at both sides of the fixing member 10. The plane in which the operating member 80 lies may be perpendicular to the central axis 90. The external force may act on one side of the operation element 80 or both sides of the operation element 80, which may rotate the operation element 80 along the central axis 90 of the tool 1000, and may drive the tool 100 to rotate as a whole.

In summary, referring to fig. 1-3, an application process of the dismounting tool 100 according to the embodiment of the present disclosure is as follows:

when the dismounting tool 100 needs to loosen the nut 200 or tighten the nut 200: the adjusting member 50 is manually pressed to move the adjusting member 50 in the second direction, and the adjusting member 50 can drive the moving member 20 to move in the second direction. At this time, the adjusting member 50 moves in the second direction in synchronization with the moving member 20, and the elastic member 60 is elastically deformed.

Meanwhile, the two clamping jaws 30 can be unfolded away from the central axis 90 of the disassembling tool 100 under the action of the moving member 20 and the sliding groove 33, and the second ends 32 of the two clamping jaws 30 are far away from each other. When the spread of the two jaws 30 matches the notch 210 on the same axis of the nut 200, the manual pressing of the adjusting member 50 is cancelled. Since the elastic member 60 has an elastic deformation at this point, the elastic member 60 can restore the elastic deformation after the manual pressing of the adjusting member 50 is canceled. The elastic member 60 returns to the deformation process to provide a force to the adjusting member 50 to move in the first direction, so that the adjusting member 50 and the moving member 20 move in the first direction. The moving member 20 can drive the clamping jaws 30 to approach the central axis 90 of the disassembling tool 100, the second ends 32 of the two clamping jaws 30 are gathered together, and the clamping jaws 30 can clamp the notch 210 of the nut 200.

Finally, the operator 80 of the tool 100 is rotated in the same direction depending on the direction of rotation required to loosen the nut 200 or tighten the nut 200. The rotation operation member 80 can drive the whole assembly and disassembly tool 100 to rotate, and the clamping jaws 30 clamp the notches 210 of the nut 200, so that the nut 200 can rotate synchronously, and the operation of loosening or tightening the nut 200 can be completed.

While embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that: numerous changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the application, the scope of which is defined by the claims and their equivalents.
