[0026] In this embodiment, by rotating the rotary knob 1 601, gear 1 602 and gear 2 603 can be driven to rotate. Driven by the transmission belt, gear 3 604 and gear 4 605 can be rotated at the same time, thereby driving the two threaded rods 606 to rotate together. Under the interaction between the external thread of the threaded rod 606 and the internal thread of the threaded seat 607, the threaded seat 607 can drive the mounting bracket 608 to move left and right.

[0028] In this embodiment, by clamping the limiting rod into the corresponding first limiting hole 610 and second limiting hole 611, the threaded seat 607 can be fixed to prevent the threaded seat 607 from shifting.

[0029] Specifically, the limiting component 9 includes a rotating knob 2 901, a rotating knob 2 901 is provided on the top of the fixing frame 8, a rotating shaft of the rotating knob 2 901 is fixedly installed with a bevel gear 1 902, the surface of the bevel gear 1 902 is meshed with a bevel gear 2 903, the side of the bevel gear 2 903 is fixedly connected with a screw rod 904, the surface of the screw rod 904 is threadedly connected with a movable plate 905, the side of the movable plate 905 is fixedly installed with a clamping plate 906, a clamping groove 907 is opened on the inner side of the mounting seat 3, and the clamping plate 906 fits with the clamping groove 907.

[0030] In this embodiment, rotating knob 2 901 can drive bevel gear 1 902 to rotate. Under the meshing transmission of the bevel gears, bevel gear 2 903 can drive screw rod 904 to rotate, thereby enabling movable plate 905 and clamping plate 906 to move.

[0031] Specifically, there are two screw rods 904 and two movable plates 905 . The surfaces of the two screw rods 904 are provided with two opposite external threads, and the interiors of the two movable plates 905 are provided with internal threads, and the external threads of the two screw rods 904 are matched with the internal threads of the two movable plates 905 .

[0032] In this embodiment, the two screw rods 904 rotate to allow the two movable plates 905 to move inward or outward at the same time.

[0033] Specifically, a limiting rod 908 is fixedly installed inside the fixing frame 8 , and the movable plate 905 is slidably connected to the limiting rod 908 .

[0034] In this embodiment, the movable plate 905 can slide on the surface of the limiting rod 908 and can play a limiting role.

[0035] Specifically, a rotating shaft 1 4 is fixedly installed on the front and rear sides of the motor base 1 , a rotating shaft 2 5 is fixedly installed on the front and rear sides of the mounting base 3 , and a connecting rod 2 is movably connected to the outer sides of the rotating shaft 1 4 and the rotating shaft 2 5 .

[0036] In this embodiment, the connecting rod 2 can rotate on the surfaces of the first rotating shaft 4 and the second rotating shaft 5, so that the angle of the connecting rod 2 can be adjusted.

[0037] The working principle and usage process of the present invention: During use, when it is necessary to adjust the angle of the motor output shaft, first take out the limiting rods in the first limiting hole 610 and the second limiting hole 611, and then rotate the rotary knob 1 601 to drive gear 1 602 and gear 2 603 to rotate, so that gear 3 604 and gear 4 605 can rotate at the same time, thereby driving the two threaded rods 606 to rotate together, so that the threaded seat 607 can drive the mounting bracket 608 to move left and right together, at this time, the end of the mounting bracket 3 close to the rotating bracket 609 can move, and the middle position of the mounting bracket 3 rotates under the action of the connecting rod 2, so that the angle of the mounting bracket 3 and the motor on the top of the mounting bracket 3 can be quickly adjusted, and finally when the angle of the motor output shaft is adjusted, the limiting rod is clamped in the corresponding first limiting hole 610 and the second limiting hole 611 to fix the threaded seat 607 and prevent the screw from being screwed. The groove seat 607 is displaced. Compared with the method of adjusting the angle of the motor base 1, the motor of the present application is more convenient to adjust the output shaft angle; when it is necessary to disassemble the motor body 7, first rotate the rotary knob 2 901 to drive the bevel gear 1 902 to rotate, so that the bevel gear 2 903 can drive the screw rod 904 to rotate, thereby allowing the movable plate 905 and the card plate 906 to move. When the card plate 906 is out of the slot 907, the motor body 7 can be easily removed; when it is necessary to install the motor body 7, align the motor body 7 with the mounting seat 3 and place it, and rotate the rotary knob 2 901 in the opposite direction so that the card plate 906 is engaged in the slot 907, so that the fixing frame 8 and the mounting seat 3 can be connected together, thereby installing the motor body 7 on the motor base 1. Compared with the bolt fixing method, the motor body 7 of the present application is faster to disassemble and assemble, which is convenient for the staff to inspect and repair the motor body 7.
