When in use, the internal threaded sleeve 4 is rotated simultaneously through the connecting rib 5. Since the internal threads of the two internal threaded sleeves 4 are arranged in opposite directions, when the internal threaded sleeve 4 rotates, the adjacent ends of the upper pull rod 2 and the lower pull rod 3 are simultaneously moved closer or farther away, thereby achieving the purpose of adjusting the length between the upper pull rod 2 and the lower pull rod 3. Among them, a first hook groove 111 is provided on the right side wall of the first connecting block 11, and a first connecting column 31 is provided at one end of the lower pull rod 3, and the first connecting column 31 is clamped in the first hook groove 111.

In this way, the first connecting post 31 can be prevented from escaping from the first hook groove 111. When the first connecting post 31 needs to enter the first hook groove, the lower pull rod 3 is swung so that the first transition groove on the first connecting post 31 is opposite to the first limit block 33, and the first limit block 33 passes through the first transition groove, so that the first connecting post 31 enters the first hook groove 111. After the lower pull rod 3 is connected to the upper pull rod 2, the first transition groove and the first limit block 33 are staggered, and the first connecting post 31 cannot escaping from the first hook groove. The function of the second limiting block 23 is similar to that of the first limiting block 33 , which is to prevent the second connecting column 21 from being separated from the second hook groove 121 .
