The basic idea of the wire binding forceps described in this embodiment is as follows: when the two clamp arms are combined together through a power device (as shown by a solid line in figure 1), a bent channel is formed by the clamp arms and the guide sheet, and the head of the binding wire can smoothly and smoothly rotate in the channel by the action of forward jacking of the wire feeder to bypass the door bolt and the door buckle, so that the door bolt and the door buckle are surrounded. Then the binding wire is screwed up through a series of actions of fixing the head end or the tail end of the binding wire, cutting the tail end, screwing up and the like.

The wire feeder may use two wheels with rims aligned, a pinch and a spindle, to feed the binding wire out and create the previous pushing action. The binding wire can also be put in the V-shaped groove by adopting a clamping wheel, namely a wheel with a V-shaped wheel rim, and the binding wire is pushed to move forwards by utilizing the friction force at the two sides of the V-shaped groove when the clamping wheel rotates.

The cutting knife should be capable of cutting the tail end of the binding wire, and the head end and the tail end of the binding wire can be cut simultaneously for neatness and beauty.

The rotating seat can be driven to rotate through a rotating shaft 401 (see fig. 1), a pressing block is arranged on the rotating seat, and the pressing block can clamp and fix the head end and the tail end of the binding wire.

The cutting knife and the pressing block can adopt electromagnets as driving devices to form cutting and locking actions. The cutting and locking can be carried out simultaneously by adopting a linkage device, and the cutting and locking can also be respectively provided with electromagnets to respectively act.

One end of each clamp arm is provided with a rotating shaft of the hinge, so that the clamp arms can swing to open and close through the power device, the other end of each clamp arm is semicircular, and the two clamp arms are closed to be close to a circle and used for forming a closed lock for the door bolt and the door buckle. The clamp arm is provided with a groove which is used for guiding the movement of the head end of the binding wire.

The power device for pushing the clamp arms to open and close can generate torque, such as an electric motor, a hydraulic motor or a pneumatic motor. The linear pushing device can convert the linear motion into the rotary motion through a connecting rod mechanism.

The front-out guide piece and the back-up guide piece are two elastic guide pieces, can block the movement of the head end of the binding wire, and can be bounced off when the clamp arms are opened, so that the binding wire is released from the groove.
