After the first slider 302 is locked, the locking cam 303 is unlocked and the locking cam 304 is unlocked, so that the first slider 302 can no longer be locked in the locking cam 303.

[0027] As a technical optimization solution of the present invention, the cross-section of the first slider 302 is a "T"-shaped structure, and the end of the limit block 304 located in the limit groove 303 is a triangular structure; the cross-section of the first slider 302 is a "T"-shaped structure, which can prevent the first slider 302 from slipping off the mounting seat 301, thereby increasing the stability of the first slider 302; the end of the limit block 304 located in the limit groove 303 is a triangular structure, which has a guiding effect on the limit block 304, making it easy for the limit block 304 to quickly engage into the limit groove 303.
