When the folding adjusting support mechanism needs to be rotated and supported on the ground, first, the support leg 8 is pulled to rotate in the U-shaped seat 7 until it is rotated to a position away from one side of the first rectangular frame 12. Then, the operator holds the first handle 9 and drives the first screw rod 10 to rotate manually. With the rotation of the first screw rod 10, the base plate 11 is gradually brought close to and tightly attached to the ground, thereby achieving a stable support effect on the mobile support. Conversely, when the support needs to be folded or adjusted, the first handle 9 is operated in the reverse direction to make the first screw rod 10 rotate and drive the base plate 11 away from the ground, and then the support leg 8 is rotated back to the original position.

When the longitudinal lifting support mechanism is operated to tightly attach to the bottom of the support beam, first, the second handle 26 is held tightly and the second screw rod 25 is driven to start rotating manually. At the same time, the third screw rod 27 also rotates synchronously. With the continuous rotation of the second screw rod 25 and the third screw rod 27, the lifting support rod 22 threadedly connected to the second screw rod 25 and the third screw rod 27 starts to rise slowly. The lifting of the lifting support rod 22 drives the base wood 24 between the two groove plates 23 to rise together until the base wood 24 is attached to the lower side of the support beam. Since the base wood 24 is made of flexible material, it can play a buffering role after the support beam is cut off, reducing the impact force generated by the cutting. Furthermore, it not only can conveniently adjust the attachment degree between the base wood 24 and the support beam to ensure stable support effect, but also can provide necessary buffer protection after the support beam is cut off.
