[0026] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] like Figure 1-Figure 2 As shown, the present application provides a stepper motor, including a housing 1, and a motor assembly 5 is arranged on the housing 1, and the motor assembly 5 is used to provide driving force for a device connected thereto;

[0029] like Figure 1-Figure 2 and Figure 5 As shown, the motor assembly 5 includes a slot 51 opened on the housing 1, and a plurality of pins 52 are arranged inside the slot 51. One end of the pin 52 is electrically connected to a terminal block 53, so that the female plug of the external power source is inserted into the slot 51 and connected to the pin 52. The terminal block 53 is located inside the housing 1;

[0030] At the same time, a wire protection box 54 is arranged on one side of the terminal block 53, and a stator part 510 is arranged inside the shell 1, and a rotor part 59 is arranged inside the stator part 510, and a first bearing 55 and a second bearing 58 are respectively installed on the inside of the shell 1, and a rotor part 59 is arranged on the first bearing 55 and the second bearing 58, and a gasket 57 is arranged between the first bearing 55 and the rotor part 59, and a copper ball 56 is arranged between the first bearing 55 and the terminal block 53, and a guide frame 511 is arranged on one side of the shell 1. It should be noted that part of the rotor part 59 is located inside the guide frame 511, and a cone head 513 is arranged outside the guide frame 511, and a spring 512 is arranged inside the cone head 513 and outside the guide frame 511 to absorb the impact or vibration of the guide frame 511 to a certain extent due to the movement of the rotor part 59 when the rotor part 59 rotates. It should be noted that the above structure constitutes a motor assembly 5, and the motor assembly 5 is a prior art, and the specific structure and principle are not described in detail here.

[0031] Meanwhile, a hinge assembly 3 is provided on the housing 1, and the hinge assembly 3 is used to directly display the pin 52;

[0032] like Figure 2-Figure 3 As shown, the hinge assembly 3 includes a lower hinge 31 fixedly mounted on the housing 1, and an upper hinge 33 is hinged on the lower hinge 31, and a frame plate 32 is fixedly mounted on the upper hinge 33, and a groove adapted to the frame plate 32 is opened on the housing 1, and the frame plate 32 is located inside the groove, and the groove is connected to the slot 51. It should be noted that the hinge point of the lower hinge 31 and the upper hinge 33 is far away from the groove, so that when the frame plate 32 is hinged, it can be set in a seam with the housing 1;

[0033] When an external power source needs to be connected, the frame plate 32 is rotated to drive the upper hinge 33 to rotate on the lower hinge 31, so as to display the pins 52 in the motor assembly 5, and then the motor assembly 5 is accurately connected to the female plug of the external power source;

[0034] Meanwhile, a locking assembly 2 is provided on the housing 1, and the locking assembly 2 is used to lock the hinge assembly 3;

[0035] like Figure 2-Figure 4 As shown, the locking assembly 2 includes a mounting frame 21 fixedly mounted on the housing 1, a cushion block 28 fixedly mounted on the mounting frame 21, a screw (not shown in the figure) fixedly mounted on the cushion block 28, a lock hook 24 rotatably mounted on the screw, a rotary rod 25 fixedly mounted on the lock hook 24, a fixed rod 22 fixedly mounted on the mounting frame 21, and a tension spring 23 is commonly connected to one end of the fixed rod 22 and the lock hook 24, a fixed frame 27 fixedly mounted on the frame plate 32, and a lock buckle 26 detachably mounted on the fixed frame 27;

[0036] In the initial state, the lock hook 24 hooks the lock buckle 26 to lock the frame plate 32. When the external power supply is connected, the rotary rod 25 is rotated to drive the lock hook 24 to rotate on the screw rod. At this time, the lock hook 24 stretches the tension spring 23 and separates from the lock buckle 26, so that the lock of the frame plate 32 can be released.

[0037] At the same time, a limit assembly 4 is provided on the locking assembly 2, and the limit assembly 4 is used to limit the lock hook 24;

[0038] like Figure 4 As shown, the limiting assembly 4 includes a mounting block 41 fixedly mounted on the mounting frame 21, and a limiting rod 42 is provided on the mounting block 41. It should be noted that the mounting block 41 is parallel to the locking hook 24 in the initial state, and the limiting rod 42 is perpendicular to the mounting block 41 and the limiting rod 42;

[0039] After the lock hook 24 releases the lock on the frame plate 32, the rotating rod 25 is loosened, and the tension spring 23 is reset to drive the lock hook 24 to reset. At this time, when the lock hook 24 rotates on the screw rod, it will be pushed by the limit rod 42 to prevent it from continuing to rotate on the screw rod, causing the connection between the tension spring 23 and the lock hook 24 to loosen;

[0040] To summarize, when connecting the motor to an external power supply, the hinge assembly 3 is unlocked by the locking assembly 2, and the locking assembly 2 is released. At this time, the limit assembly 4 restricts the lock hook 24 in the locking assembly 2, and then the hinge assembly 3 is rotated so that the multiple groups of pins 52 in the motor assembly 5 can be directly displayed. Then, the motor assembly 5 is accurately connected to the female plug of the power supply. After the connection is completed, the hinge assembly 3 is closed and locked by the locking assembly 2.
