Example

[0022] Reference Figure 3, which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0023] In this embodiment, the support beam 33 and the load-bearing beam 32 are movably connected via a pin shaft, the slider 36 is movably connected to the support beam 33 via a movable pin, and the connecting seat 31 is fixedly connected to the middle beam 1 and the cross beam 2.
