The electric drive main unit 2 can move relative to the door frame seat 1. As a driving member for expanding and contracting the telescopic gate, the length of the telescopic fence 3 can be changed by telescoping.

[0032] When the electric drive main unit 2 is working, the driving motor 26 drives the driving gear 27 to rotate, and the driving gear 27 is meshed and connected with the driven gear 23, so the driven gear 23 will rotate synchronously, so it will further drive the transmission shaft 22 to rotate, and finally drive the driving roller 24 to move through the transmission shaft 22. If the driving motor 26 rotates forward, the driving roller 24 will rotate clockwise, and the electric drive main unit 2 will move right as a whole, pulling the telescopic fence 3 to expand section by section. Similarly, if the driving motor 26 rotates reversely, the driving roller 24 will rotate counterclockwise, and the electric drive main unit 2 will move left as a whole, pushing the telescopic fence 3 to retract section by section.

After the wireless signal receiver 214 receives the wireless signal from the wireless signal transmitter 4, it will transmit the signal to the circuit board 5. The single-chip microcomputer 51 on the circuit board 5 will control the drive motor 26 to rotate forward, reverse or stop. The drive motor 26 drives the active gear 27 to rotate. The active gear 27 is meshed and connected with the driven gear 23, so the driven gear 23 will rotate synchronously, so it will further drive the transmission shaft 22 to rotate, and finally drive the drive roller 24 to move through the transmission shaft 22.
