When the pull rod 20 is pulled, the pull rod 20 moves in the movable hole 17, and the pull rod 20 drives the limit block 16 to descend, so that the limit block 16 is separated from the hand wheel 7. The staff can turn the hand wheel 7 and release the pull rod 20. The limit block 16 can clamp the hand wheel 7 through the elastic force of the two springs 9 to prevent the hand wheel 7 from rotating. The two screw sleeves 5 are meshed and connected with the screw rod 14. The outer threads of the screw rod 14 are distributed in opposite directions. The two screw sleeves 5 can be made on the screw rod 14 in opposite or opposite directions. In order to prevent the two screw sleeves 5 from shaking, a connecting plate 15 is welded in the middle of the top of the bottom plate 1. The connecting plate 15 is embedded with a bearing 19. The screw rod 14 is fixedly connected to the inner ring of the bearing 19. The bearing 19 fixes the screw rod 14 to increase the stability of the screw rod 14. A connecting plate 4 is welded to the top of the two screw sleeves 5, and a retaining frame 2 is welded to the opposite side of the two connecting plates 4. Rollers 3 are equidistantly installed inside the two retaining frames 2 for rotation. The rollers 3 inside the two retaining frames 2 extend out of the retaining frames 2. When the rollers 3 contact the slider, the retaining frames 2 will not interfere with the slider. Two support plates 10 are symmetrically welded to the bottom of the base plate 1. The two support plates 10 are symmetrically provided with fixing holes 18. The support plates 10 are fixed to the bearing structure through the fixing holes 18 of the support plates 10 using bolts and other tools.

The two screw sleeves 5 drive the two retaining frames 2 to move in relative directions through the two connecting plates 14, so that the rollers 3 inside the two retaining frames 2 are in contact with both sides of the slider. According to the actual situation, adjust the friction between the rollers 3 inside the two retaining frames 2 and the slider. When the slider moves, the rollers 3 inside the two retaining frames 2 rotate with the movement of the slider.
