The sliding rod 16 is a regular polygonal prism matched with the first plug rod 6, and the driving blocks 15 are evenly distributed on the circumferential side wall of the sliding rod 16. The side wall of the first plug rod 6 is provided with a receiving groove 17 corresponding to the driving block 15, and the receiving groove 17 is movably connected with the second plug rod 7 matched with the inclined surface of the driving block 15. The inner wall of the first socket 4 is provided with a second socket 5 matched with the second plug rod 7, the second plug rod 7 corresponds one-to-one with the driving block 15, the second socket 5 corresponds one-to-one with the second plug rod 7, and the second plug rod 7 is plugged and matched with the second socket 5.

[0032] Furthermore, in order to increase the stability between the thread 8 and the drive nut 9 , a spring 14 is provided between one end of the sliding rod 16 and the inner wall of the mounting groove 13 .
