[0012] Through the above scheme, the rotating groove 31 is set on one side of the fixed block 3, and the protrusion 21 is inserted into the rotating groove 31 to squeeze the compression spring 32, so that the compression spring 32 is built into the rotating groove 31, avoiding the compression spring 32 from being exposed, which is more beautiful and can protect the compression spring 32 from damage.
[0013] As an improved specific implementation, a spring hole 33 is provided on the bottom surface of the rotating groove 31 , and one end of the compression spring 32 is connected to the spring hole 33 .
[0014] Through the above solution, the spring hole 33 can limit and accommodate the compression spring 32, playing a role of protection and guidance.
[0015] As an improved specific implementation, the other end of the compression spring 32 is connected to a pressing piece 34 for abutting against the protrusion 21 .
[0016] Through the above solution, the pressing plate 34 can make the force more uniform, reduce friction and avoid scratches and wear.
[0017] As an improved specific implementation, the pressing sheet 34 is provided with a connecting rod 341 inserted into the compression spring 32 .
[0018] Through the above solution, the connecting rod 341 makes the connection tighter, plays a certain guiding role, and can also maintain structural stability.
[0019] As an improved specific implementation, both ends of the fixed block 3 are provided with limit plates 35 , and the two limit plates 35 are respectively provided on both sides of the rotating block 2 .
