The linear slide 41 is installed on the lower surface of the fork body 1, and the slider 42 is used in conjunction with the linear slide 41.

[0028] The screw tensioning assembly 3 includes a reverse-welded screw 31, a screw locking nut 32, a support rod connecting seat 33 and a support rod 34, wherein the reverse-welded screw 31 is welded in sequence by a first screw 311, a second screw 312, a third screw 313 and a fourth screw 314, the first screw 311 and the second screw 312 are welded in reverse, the third screw 313 and the fourth screw 314 are welded in reverse, the first screw 311 and the second screw 312 are the same size, the third screw 313 and the fourth screw 314 are the same size, the diameter of the third screw 313 and the fourth screw 314 is larger than the diameter of the first screw 311 and the second screw 312, the end of the fourth screw 314 is connected to the transmission chain 6, when the reduction motor 5 drives the transmission chain 6 to transmit, the transmission chain 6 transmits power to the fourth screw 314, and then transmits it to the third screw 313, the second screw 312 and the first screw 311.

[0029] The screw locking nut 32 includes a first screw locking nut 321, a second screw locking nut 322, a third screw locking nut 323 and a fourth screw locking nut 324. The first screw locking nut 321 is installed on the first screw 311, the second screw locking nut 322 is installed on the second screw 312, the third screw locking nut 323 is installed on the third screw 313, and the fourth screw locking nut 324 is installed on the fourth screw 314. When the transmission chain 6 drives the welded first screw 311, the second screw 312, the third screw 313 and the fourth screw 314 to rotate, the first screw locking nut 321, the second screw locking nut 322, the third screw locking nut 323 and the fourth screw locking nut 324 move in opposite directions along the welded first screw 311, the second screw 312, the third screw 313 and the fourth screw 314.
