[0024] During operation, when the position of the operating shaft 14 needs to be fixed and not operated, the motor 9 is started to make the screw rod 7 rotate inside the sliding groove 6. Since the screw rod 7 is threadedly connected to the moving block 8, the moving block 8 can be moved on the circumferential surface of the screw rod 7. Since the upper end of the moving block 8 is fixedly connected to the clamping plate 12, the moving block 8 can drive the clamping plate 12 to enter the fixed groove 15. At this time, the clamping plate 12 can enter the fixed groove 15 for fixation. At this time, the operator can mistakenly operate the load mechanism to ground, causing an accident.
[0025] See also Figure 1-4 The utility model provides a technical solution: two limit grooves 11 are opened at the upper end of the load mechanism 1, and sliders are slidably connected inside the two limit grooves 11. The left and right ends of the moving block 8 are fixedly connected with fixed plates 10, and the upper ends of the two sliders are fixedly connected to the lower ends of the two fixed plates 10 respectively.
[0026] During operation, when the moving block 8 is moving, both ends of the moving block 8 are fixedly connected to the fixed plate 10, and the fixed plate 10 is fixedly connected to the two sliders, so that the movement of the moving block 8 can be limited.
[0027] See also Figure 1-4 The utility model provides a technical solution: a card slot 5 is provided at the connection between the connecting plate 3 and the load mechanism 1 .
[0028] During operation, the position of the connecting plate 3 can be fixed by the engagement of the clamping groove 5 with the screw nut.
[0029] See also Figure 1-4 The utility model provides a technical solution: the upper end of the connecting plate 3 is fixedly connected with a control board 18, and a signal connection is established between the control board 18 and the motor 9.
[0030] During operation, the start and stop of the motor 9 can be controlled by the control panel 18 .

[0036] During operation, the anti-skid pad 17 prevents the rotating plate 16 from slipping when rotating.
[0037] In summary, when the position of the operating shaft 14 needs to be fixed and not operated, the motor 9 is started to make the screw rod 7 rotate inside the sliding groove 6. Since the screw rod 7 is threadedly connected to the moving block 8, the moving block 8 can be moved on the circumferential surface of the screw rod 7. Since the upper end of the moving block 8 is fixedly connected to the clamping plate 12, the moving block 8 can drive the clamping plate 12 to enter the fixed groove 15. At this time, the clamping plate 12 can enter the fixed groove 15 for fixation. At this time, the operator can mistakenly operate the load mechanism to ground, causing an accident.
