In one embodiment, a protection cavity is formed between the sliding member 41 and the housing 1, and the cylindrical spring is located in the protection cavity.

Referring to fig. 1 to 5, the lock provided by the utility model includes a lock core and a handle reversing mechanism, wherein the lock core is in transmission connection with a rotating piece 3. Therefore, due to the adoption of the handle reversing mechanism, the handle 2 rotates around a preset axis and is pivoted on the base body 1, and the handle 2 can rotate around the preset axis relative to the base body 1; the rotating piece 3 is arranged on the handle 2, and the rotating piece 3 can be driven to rotate around a preset axis by the rotation of the handle 2; the wiring harness 5 can sequentially pass through the first wire passing channel 31 on the rotating part 3 and the second wire passing channel 21 on the handle 2, so that the wiring harness 5 can rotate along with the handle 2 and the rotating part 3 in the process of rotating the handle 2, and the wiring harness 5 is not easy to be damaged; the rotary member 3 can be switched between a first rotary position and a second rotary position; when the rotating part 3 is located at the first rotating position, if the handle 2 drives the rotating part 3 to rotate and deviate from the first rotating position, and then the handle 2 removes the external force, the reset mechanism 4 can restore the rotating part 3 to the first rotating position, so that the stability of the position of the rotating part 3 is ensured, and the condition that the wire harness 5 passing through the first wire passing channel 31 and the second wire passing channel 21 is sprained is also reduced; when the rotating part 3 is located at the second rotating position, if the handle 2 drives the rotating part 3 to rotate and deviate from the second rotating position, and then the handle 2 removes the external force, the reset mechanism 4 can restore the rotating part 3 to the second rotating position, so that the stability of the position of the rotating part 3 is ensured, and the condition that the wire harness 5 passing through the first wire passing channel 31 and the second wire passing channel 21 is sprained is also reduced; when the user needs to adjust the initial position of the handle 2, it is only necessary to rotate the rotation member 3 from the first rotation position to the second rotation position, or to rotate the rotation member 3 from the second rotation position to the first rotation position.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the utility model, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
