In this embodiment, a plurality of avoidance grooves are provided on the bottom cover 2, and a connecting hole is provided in the outer shell 1. The connecting hole corresponds to the avoidance groove, and an internal thread is formed in the connecting hole. A screw is connected at the avoidance groove, and the screw is threadedly connected to the connecting hole, thereby fixing the bottom cover 2 to the outer shell 1.

[0026] The number of the avoidance grooves is two or three. In the case of two avoidance grooves, the two avoidance grooves are arranged opposite to each other, which can make the installation of the bottom cover 2 more stable.

[0027] The bottom cover 2 and the outer shell 1 can also be detachably connected by means of a snap fastener.

[0028] The bottom cover 2 is provided with a first power interface 3, wherein the first power interface 3 may be a TYPE-C interface, or may be a conventional interface such as a USB interface, the first power interface 3 may be directly connected to a power cord, or may be connected to an external power source;

[0029] A convex portion 51 or a recessed space 4 with an opening is formed between the bottom cover 2 and the end of the shell 1. Specifically, in the first embodiment, a recessed space 4 is formed between the bottom cover 2 and the end of the shell 1. The recessed space 4 can be used for plugging an external power supply, so that the installation between the shell 1 and the external power supply is more stable.

[0030] In the second embodiment, a convex portion 51 is formed between the bottom cover 2 and the end of the housing 1. If there is an external power supply unit 5, a groove is formed at the external power supply unit 5, which also makes the installation between the housing 1 and the power supply unit 5 more stable.

[0031] Both connection methods are available.

[0032] The motor is provided with a switch key and an indicator light.

[0033] Reference Figure 2 and Figure 3 As shown, it also includes a power supply member 5, one end of which is formed with a groove portion that matches the convex portion 51 or a ridge that matches the concave space 4;

[0034] The groove part cooperates with the protrusion 51 of the housing 1 to form a plug-in connection;

[0035] The recessed space 4 cooperates with the raised portion to form a plug-in connection.

[0036] When the power supply unit 5 needs to be charged, it can be realized by simply disassembling the power supply unit 5 and the housing 1 without removing the entire motor.

[0037] Reference Figure 3 As shown, a power connector 52 is provided at one end of the power supply unit 5 facing the first power interface 3 , and the power connector 52 is adapted to the first power interface 3 so that the power supply unit 5 can supply power to the motor.
