One end of the two groups of movable rods 4071 passes through the opposite side walls of the two groups of fixed plates 4072 and is connected to the rack 4070 provided in the second cavity 406. The rack 4070 is meshed with the teeth 411. The left and right side walls of the second cavity 406 are both provided with connecting grooves 405, and the connecting grooves 405 match the racks 4070, and the connecting grooves 405 are connected to the concave grooves 411. The grooves 404 are interconnected, so that the rack 4070 can pass through the connecting groove 405 and mesh with the tooth 411. The outer walls of the two groups of movable rods 4071 are sleeved with return springs 4075. One end of the two groups of return springs 4075 are connected to the side walls away from the two groups of movable plates 4074, and the other ends of the two groups of return springs 4075 are connected to the opposite side walls of the two groups of fixed plates 4072.

[0041] Working principle: When the variable frequency motor 2 needs to be installed on the bracket 1 of the mechanical equipment, the base 6 is placed on the bracket 1. At this time, the tail of the variable frequency motor 2 is located on the support seat 401. The staff rotates the second nut 8 to connect with the bolt 5 to fix the variable frequency motor 2 on the bracket. Then the staff squeezes the pressure plate 305 to drive the pull rod 304 to squeeze the movable block 314. The movable block 314 moves downward on the outer wall of the slide rod 309 to squeeze the first spring 310. The movable opening 314 drives the connecting rod 308 downward, and the connecting rod 308 drives the abutting rod 307 to rotate and be stored in the slot 311 The rod 302 is then pressed downward, and the bottom of the rod 302 passes through the opening 11 and enters the abutment groove 10. The pressure plate 305 is then released, and the abutment rod 307 is reset with the cooperation of the first spring 310 and abuts against the inner wall of the abutment groove 10. The staff rotates the locking nut 301 to drive the rod 302 to move upward. At this time, the locking nut 301 abuts against the connecting frame 9, and the rod 302 drives the abutment rod 307 to squeeze the top of the inner wall of the abutment groove 10, so that the second nut 8 can be fixed on the bolt 5 to prevent the vibration of the variable frequency motor 2 from causing the second nut 8 to loosen.

[0042] The staff then pulls the pull block 4073 to drive the movable plate 4074 and the movable rod 4071 to move relative to each other, and the movable rod 4071 drives the rack 4070 to move, and the movable plate 4074 can stretch the reset spring 4075. Then the staff fixes the two sets of pull blocks 4073, and the staff rotates the rotating frame 408 to drive the first nut 409 to rotate. The first nut 409 moves downward on the outer wall of the screw rod 402, and drives the extrusion seat 403 to move downward to squeeze the frequency conversion motor 2, which can provide additional fixed support for the frequency conversion motor 2 to increase the stability and reliability of the fixation and form a more stable support system. When the first nut 409 rotates into the groove 404, the staff releases the two sets of pull blocks 4073, and under the action of the elastic force of the reset spring 4075, the rack 4070 engages with the tooth 411, which can prevent the vibration of the frequency conversion motor 2 from causing the first nut 409 to loosen, thereby improving the installation stability.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
