[0027] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.

[0028] The working principle of the above embodiment is:

[0029] (1) When the support bracket needs to be moved, the first motor 201 is started so that the first motor 201 can drive the rotating rod 202 to rotate, thereby enabling the vertical gear 203 to rotate. Through the engagement of the vertical gear 203 with the horizontal gear 204, the horizontal gear 204 can rotate, thereby enabling the horizontal gear 204 to drive the first threaded rod 205 to rotate. Through the operation of the first threaded rod 205, the movable plate 206 can be moved, thereby enabling the movable plate 206 to drive the fixed column 207 and the universal wheel 208 to move, thereby enabling the universal wheel 208 to contact the ground, thereby enabling the support bracket to move. After moving to the designated position, the first motor 201 is reversed to enable the movable component 2 to retract into the interior of the base 1, thereby achieving the purpose of conveniently moving the support bracket.

[0030] (2) When the height of the support bracket needs to be adjusted, the electromagnet 7 is started so that the electromagnet 7 can adsorb the plug rod 9, thereby allowing the plug rod 9 to retract and compress the spring 8. Then, the second motor 4 is operated to rotate the second threaded rod 5. The second threaded rod 5 is connected to the lifting rod 6 through a thread, so that the lifting rod 6 can be raised and lowered. When the lifting rod 6 moves to the specified position, the electromagnet 7 is powered off so that the electromagnet 7 will no longer adsorb the plug rod 9, so that the plug rod 9 can rebound through the action of the spring 8, and the plug rod 9 can be connected to the socket inside the support column 3. When the support plate 10 rises, it will drive the viscous damper 12 to operate. When the support plate 10 supports the bridge, the viscous damper 12 can reduce the vibration of the support plate 10, thereby improving the vibration reduction effect of the support bracket and improving the stability of the support bracket during operation.
