A hook is provided on the outside of the handle 8. The handle 8 is provided with a slot corresponding to the position of the latch 9. When the upper end of the latch 9 is inserted into the slot, the handle 8 cannot be rotated. When the latch 9 moves down and out of the slot, the handle 8 can be rotated to drive the hook to rotate to realize whether the other side panel is stuck.

[0033] The flipping mechanism 62 includes a hydraulic cylinder 621, a main cylinder body 622, a gear set (not shown) and a rotating shaft 623.

The gear set converts the linear motion of the piston rod into the rotational motion of the rotating shaft 23. The hydraulic cylinder 21 drives the rotating shaft 23 to rotate through the gear set. The rotating shaft 23 is fixedly connected to the unlocking flip plate 63. The clamping plate 65 is provided with a slot 65a. The cross-sectional size of the slot is large at the lower end and small at the upper end. The flipping center axis X1 of the unlocking flip plate 63 and the rotation center axis Y1 of the clamping plate 65 are perpendicular to each other.

[0034] Specifically, the installation device 1 is a mobile device, preferably a mobile forklift, which can open and close the turnover box and move it to different places for stacking and use, which is very convenient. The equipment also includes a visual detection system and a turnover box position detector. The visual detection system uses a camera to take pictures to identify whether there are foreign objects inside the turnover box. The turnover box position detector is used to identify whether the turnover box is in the correct position. The turnover box position detector can be a micro switch or a sensor.
