The motor 4 is turned on, so that the motor 4 drives the worm 5 to rotate, the gear 6 in threaded connection with the worm 5 will rotate with the rotating shaft 7, and the transmission assembly rotatably connected with the rotating shaft 7 will lift and lower with the insert rod 2.
In a further optimization scheme, the two sides of the motor 4 are fixedly connected with limit plates 20, and the limit plates 20 are rotatably connected with the rotating shaft 7 through bearings.
The setting of the limit plate 20 facilitates the rotation of the rotating shaft 7 and provides a certain supporting force.

One end of the connecting rod 9 extending into the chute 11 slides in the chute 11 with the rotation of the connecting rod 9. With the sliding of the connecting rod 9 in the chute 11, the sliding connection between the connecting rod 9 and the insert rod 2 causes the insert rod 2 to receive a force in the direction of the chute 11. Under the force, the insert rod 2 begins to slide in the direction of the limit hole 12, and the insert rod 2 is inserted into the ground.
In a further optimization scheme, one end of the connecting rod 9 extending into the chute 11 is provided with a limit groove 13, and one end of the insert rod 2 extending into the limit hole 12 is provided with a positioning rod 14, and the positioning rod 14 penetrates through the limit groove 13.

One end of the connecting rod 9 extending into the chute 11 slides in the chute 11 along with the rotation of the connecting rod 9. With the sliding of the connecting rod 9 in the chute 11, the sliding connection between the connecting rod 9 and the insert rod 2 enables the insert rod 2 to be inserted into the ground.
The hydraulic cylinders 15 can drive the workbench 3 to ascend and descend until the support table 18 contacts the bridge. Through the elastic deformation and recovery of the spring buffers 17 and the sliding connection of the support table 18, the buffer mechanism can effectively alleviate the influence of external impact or load on the support table 18.
