This scheme can be operated electrically, and the driving motor controls the rotation of the bidirectional screw rod and drives the two rectangular nuts to move synchronously towards each other or in the opposite direction, so as to control the front card plate and the rear card plate to snap together and hook the designated position, or to disengage in the opposite direction. The cylindrical design can be easily inserted into the circular hole of the product, and the annular boss can be hung upside down in the circular hole, with an anti-slip design, safe and reliable; a cylinder and annular boss are added to the rear card plate to match the circular hole on one side of itself, and then matched with the cylinder and annular boss design of the front card plate, so that the hook is more stable, firm and safe.
