[0045] The working principle of the utility model is as follows: when the device is in use, when the height of the support plate 11 needs to be adjusted, the installed driving member 5 drives the threaded rod 6 connected thereto to rotate, and the rotation of the threaded rod 6 drives the slider 4 connected thereto to slide in the slide groove 3 under the action of the thread, and the sliding of the slider 4 drives the scissor rod group 8 to rotate, and the rotation of the scissor rod group 8 drives the mounting seat 1 to move, and the movement of the mounting seat 1 drives the support plate 11 to move, so as to adjust the height of the support plate 11, which is convenient for construction personnel to construct at different required heights during construction, thereby improving the practicality of the device. When the device is hit or shakes during the transfer process, the support plate 11 is easily moved. The support plate 11 will move downward under the action of pressure, and the downward movement of the support plate 11 drives the connecting rod 15 to rotate. The rotation of the connecting rod 15 drives the buffer sleeve 16 to move toward each other and compress the elastic component 17 connected thereto, thereby compressing the elastic component 17 to buffer the impact force generated by the shaking. At the same time, the buffer sleeve 16 moves toward each other and drives the buffer block 20 at one end of the mounting rod 19 to slide in the buffer cavity 18.
