[0045] When inserting the insertion end into the socket 71, the length of the corrugated part 21 within the socket 71 can be adjusted according to the required insertion depth. Then, the sliding block 81 in the slot 72 of the aluminum profile is slid to the position corresponding to the corrugated part 21. The top block 82 is driven to rotate by the external attack and the mating groove 821 to form a mating. Then, the third thread 9 and the threaded hole move towards the bottom of the slot 72 and squeeze the bottom of the slot 72. The flat end 822 on the top block 82 can reduce the pressure surface on the bottom of the slot 72, thereby increasing the pressure on the corrugated part 21 after squeezing the bottom of the slot 72, and fixing the insertion end of the connecting rod 2 in the socket 71.
