When the internal When the motor 210 drives the bidirectional screw rod 209 to rotate, the two bidirectional slides 207 arranged inside the assembly bracket 106 can slide accordingly toward both sides under the drive of the bidirectional screw rod 209. Since the threads on both sides of the bidirectional screw rod 209 rotate in opposite directions, the bidirectional slides arranged on both sides of the bidirectional screw rod 209 will expand or close together at the same time.
