The movable portion 33 can be limited between the pin cap 4 and the connector 5, so that the motor pin 3 will not fall off the pin cap 4 and the connector 5; the distance between any two adjacent motor pins 3 is not equal, which plays a fool-proof role, prevents the occurrence of wire sequence installation errors, reduces the failure rate, saves installation time, and improves installation efficiency.

[0041] like Figure 1 As shown, the motor further includes a connector 8 , and the motor lead 6 is connected to the connector 8 .

[0042] Furthermore, the motor also includes a casing 1, which is covered on a part of the motor body 2 structure, and the pin cap 4 partially extends out of the casing 1, so that the motor lead 6 is also located outside the casing 1, which is convenient for connection with the connector 8.

[0043] like Figure 1-Figure 3As shown, the motor further includes a wire fixing component 7, through which the motor pin 3 is connected to the motor lead 6, so that the connection between the motor pin 3 and the motor lead 6 is more stable.

[0044] Furthermore, the wire fixing assembly 7 includes a wire fixing housing 71 and a wire fixing member 72, the wire fixing member 72 is clamped in the wire fixing housing 71, the plug-in portion 31 is plugged into one end of the wire fixing member 72, and the motor lead 6 is connected to the other end of the wire fixing member 72.
