Correspondingly, referring to fig. 2 and fig. 3, the present embodiment further provides a gap compensator 13, the gap compensator 13 is configured to compensate a gap between the first member and the second member, the gap compensator 13 is configured to be disposed in the gap, the gap compensator 13 is configured to be abutted against the first member and the second member at the same time, a compensation hole 131 is disposed on the gap compensator 13, and the compensation hole 131 is configured to deform when the gap compensator 13 is pressed by the first member and the second member.

In this embodiment, the second member is a handle 11, and the first member is a handle holder 12. The present embodiment is described in which the gap compensator 13 compensates for the gap between the handle 11 and the handle holder 12.

In actual use, the clearance between the outer wall of the handle holder 12 and the inner wall of the fitting hole of the handle 11 is small, and the clearance cannot be effectively compensated for.

In this embodiment, when the clearance compensation member 13 is used to compensate for the clearance between the handle holder 12 and the handle 11, the handle 11 and the handle holder 12 press the clearance compensation member 13, and the compensation hole 131 is deformed. When the gap compensation piece 13 compensates a small gap, a sufficient space is provided for deformation, so that the gap between the handle 11 and the handle seat 12 can be compensated, and the problem that relative movement is easy to occur between the handle 11 and the handle seat 12 is effectively solved.

Of course, in other embodiments, the first member and the second member may be any two members having a gap therebetween. For example, the first and second members may be plate-shaped structures, a gap is formed between the first and second members, the gap compensator 13 is disposed in the gap, the first and second members compress the gap compensator 13, and the compensation hole 131 is deformed, so that the gap compensator 13 can compensate the gap between the first and second members.

In this embodiment, the clearance compensator 13 has a cylindrical structure. In this way, the clearance compensation member 13 can be easily fitted to the fitting hole of the handle 11.

Referring to fig. 2 and fig. 3, in the present embodiment, specifically, the clearance compensation part 13 includes a compensation portion 132 and an abutting portion 133, the compensation hole 131 is disposed on the compensation portion 132, the compensation portion 132 and the abutting portion 133 are both cylindrical structures, one end of the compensation portion 132 is connected to an end surface of the abutting portion 133, the compensation portion 132 is provided with a first through hole 134 penetrating along an axial direction of the compensation portion 132, the abutting portion 133 is provided with a second through hole 135 penetrating along the axial direction of the abutting portion 133, and the first through hole 134 is communicated with the second through hole 135. The first piece (handle seat 12) is of a rod-shaped structure, the second piece (handle 11) is provided with a matching hole matched with the first piece, the compensation part 132 is arranged in the matching hole, the abutting part 133 is abutted to the end face of the matching hole, and the handle seat 12 is used for sequentially penetrating through the second through hole 135 and the first through hole 134.

In this way, it is possible to have the compensation portion 132 provided between the handle holder 12 and the handle 11 for compensating for the gap between the handle holder 12 and the handle 11. In addition, the abutting portion 133 abuts against the end surface of the fitting hole, so that the backlash of the clearance compensation piece 13 with respect to the handle base 12 and the handle 11 can be effectively prevented, and the mounting and dismounting of the clearance compensation piece 13 can be facilitated.

It can be understood that, in the present embodiment, the compensation portion 132 and the abutting portion 133 are both sleeved on the handle seat 12, the outer wall of the compensation portion 132 is attached to the inner wall of the mating hole, and the inner wall of the first through hole 134 is attached to the outer wall of the handle seat 12. In the process that the handle seat 12 sequentially passes through the second through hole 135 and the first through hole 134, the clearance compensation piece 13 can be extruded under the combined action of the inner wall of the matching hole and the handle seat 12, so that the compensation hole 131 is deformed.

Referring to fig. 2 and 3, it should be noted that, in the present embodiment, the compensation portion 132 and the abutting portion 133 are coaxially disposed, the first through hole 134 and the second through hole 135 are both circular holes, and the first through hole 134 and the second through hole 135 are coaxially disposed, so that the handle base 12 can sequentially pass through the second through hole 135 and the first through hole 134.

In the present embodiment, the outer diameter of the compensation portion 132 is smaller than the outer diameter of the contact portion 133. Thus, the abutting portion 133 is positioned outside the fitting hole, so that the abutting portion 133 abuts against the end surface of the fitting hole.

Referring to fig. 2 and 3, the clearance compensation element 13 further includes an extension portion 136 having a cylindrical structure, the extension portion 136 is connected to an end of the compensation portion 132 away from the abutting portion 133, the extension portion 136 is provided with a third through hole 137 axially penetrating along the extension portion 136, and the third through hole 137 is communicated with the first through hole 134.

It should be noted that, in the present embodiment, when the handle seat 12 and the handle 11 squeeze the extension portion 136, the third through hole 137 is deformed, so that the extension portion 136 has enough space to be deformed. That is, in the present embodiment, the third through hole 137 functions the same as the compensation hole 131.

In addition, referring to fig. 1 and fig. 2, in the present embodiment, after the handle seat 12 extends into the first through hole 134, one side of the extending portion 136 close to the first through hole 134 abuts against the handle seat 12. Thus, the backlash of the backlash compensator 13 with respect to the handle base 12 and the handle 11 can be effectively prevented.

Note that, in the present embodiment, the extending portion 136, the compensating portion 132, and the abutting portion 133 are integrally molded, and are made of rubber. In other embodiments, the extension 136, the compensation portion 132, and the abutment 133 may also be made of silicone or other elastic materials.

In this embodiment, the connecting member 14 is a cotter pin. The handle 11 and the handle seat 12 are respectively provided with a first mounting through hole and a second mounting through hole communicated with the connecting hole 138, and the connecting piece 14 is used for sequentially passing through the first mounting through hole, the connecting hole 138 and the second mounting through hole, so that the handle 11, the clearance compensation piece 13 and the handle seat 12 are relatively fixed. In other embodiments, the attachment member 14 may also be a screw, bolt, or the like.

Referring to fig. 2 and 3, in the present embodiment, the number of the compensation holes 131 is multiple, and the compensation holes 131 are distributed on the gap compensator 13 at intervals.

Thus, when the plurality of compensation holes 131 are simultaneously deformed, the clearance compensation member 13 as a whole can have a larger amount of deformation, so that the clearance compensation member 13 can be used to compensate for a smaller clearance.

Referring to fig. 2 and fig. 3, in the present embodiment, a portion of the compensation holes 131 are distributed side by side along a first predetermined direction, another portion of the compensation holes 131 are distributed side by side along a second predetermined direction, an included angle a between the first predetermined direction and the second predetermined direction is a, and a is 90 °. Thus, when the clearance compensation piece 13 is extruded in different directions, the plurality of compensation holes 131 distributed in different directions can be deformed, so that the clearance component can generate larger deformation in different directions.

In other embodiments, a may be 5 °, 30.3 °, 80 °, or the like.

Specifically, in the present embodiment, the first predetermined direction is a circumferential direction of the clearance compensation piece 13, and the second predetermined direction is an axial direction of the clearance compensation piece 13.

In this embodiment, the compensation hole 131 is a rectangular hole. In other embodiments, the compensation holes 131 may also be circular holes, triangular holes, etc.
