For those skilled in the art, the forward and reverse operations of the first motor 8 and the second motor 12 and the power supply to the first motor 8 and the second motor 12 are all conventional technical means, and the principle thereof will not be specifically described herein;

[0043] The using process of the auxiliary fixing device provided by the present utility model is as follows: Through the meshing of the second flat gear 9 and the first flat gear 7, starting the first motor 8 facilitates driving the ring seat 4 to flip around the first support shaft 5 and the second support shaft 6, so as to adjust and change the inclination of the clamping seat 19 during clamping. Through the meshing of the second bevel gear 13 and the first bevel gear 11, starting the second motor 12 facilitates driving the stud 10 to rotate, and then driving the second T-shaped seat 3 and the ring seat 4 to adjust the height position, so as to change the clamping height of the clamping seat 19 on the device. By rotating the ring frame 14 through the grasping handle 17, it is convenient to change the clamping position of the clamping seat 19 on the device;

[0044] When it is necessary to rotate the screw rod 21 to drive the clamping seat 19 to clamp and fix the equipment, grasp and pull the handle 27, so that the cylinder seat 25 and the fourth flat gear 26 both move away from the gear groove 23, so that the fourth flat gear 26 slides out from the inside of the gear groove 23. Then rotate the handle 27 to drive the cylinder seat 25 and the fourth flat gear 26 to rotate. Cooperate with the meshing of the fourth flat gear 26 and the third flat gear 22 to drive the screw rod 21 to rotate. After the screw rod 21 rotates, align the teeth of the fourth flat gear 26 with the teeth of the gear groove 23 and then release the handle 27. The elastic characteristic of the spring 28 facilitates the reset of the cylinder seat 25, and then makes the fourth flat gear 26 slide back into the inside of the gear groove 23 again, completing the limit fixation of the screw rod 21.
