The lever principle is used for braking, so that the braking is simple and effective, the response speed is high, and the braking efficiency is high. The brake shaft 3 in the invention is driven by the power component 4 to do linear motion in the axial direction, which is different from the rotary motion mode of the brake shaft. The axial linear motion mode is adopted, power is directly transmitted, intermediate links are reduced, electric quantity loss is reduced, and the service life of a battery is prolonged. And by adopting the movement mode, the moment loss in the rotation movement is overcome, the braking response time is shorter, and the control on the wire outlet amount is more facilitated.

In this embodiment, the driving end 22 of the brake pad 2 is located at the higher side of the driving inclined surface 31 during feeding wire, after feeding wire is completed, the driving shaft 3 moves along the axial direction under the action of the power component 4, the brake pad 2 rotates around the hinge shaft 5 under the continuous action of the driving torsion spring 51 due to the reduction of the height of the driving end 22 leaning against the driving inclined surface 31 of the driving shaft 3, so that the braking end 21 of the brake pad 2 is instantly close to a wire disc rotating at high speed due to inertia, and the braking end 21 of the brake pad 2 hooks rectangular teeth on the wire disc, so as to achieve the effect of braking the wire disc. Of course, the above-described embodiment of the present invention may also adopt a reverse braking process, i.e. the brake pad 2 is pushed close to the wire disc by the driving slope 31 and brakes, and the braking reset is released by driving the torsion spring 51.
