At the end of the shearing action, the fixed wheel 2307 is movable to avoid pushing the end of the welding wire to retract, thereby ensuring that the welding wire head can be reserved after each shearing, which is convenient for the next wire drawing.

[0036] Among them; the surface of the movable cylinder 2301 is slidably connected with a push rack 24, and a guide block 25 is integrally provided on the side of the push rack 24 away from the movable cylinder 2301, and the outer wall of the guide block 25 is slidably connected to the inner wall of the second guide hole 17, and the outer wall of the guide block 25 is fixedly connected with a connecting rack 26, and the inner wall of the connecting rack 26 is slidably connected to the surface of the guide plate 16, and the outer wall of the guide block 25 is slidably connected to the inner wall of the pressure hole 22, so as to facilitate the moving cylinder 2301 to move forward.

[0037] Among them; a baffle 27 is fixedly connected between the guide plate 16 and the reel frame 1, and a reset spring 28 is provided between the baffle 27 and the push frame 24, and the surface of the reset spring 28 is slidably connected to the surface of the baffle 27, and the surface of the reset spring 28 is fixedly connected to the outer wall of the push frame 24, so as to facilitate the reset of the device after shearing.

[0038] The outer cylinder 3 has a fixed wire hole 29 formed through the surface thereof, and the fixed wire hole 29 is in a U-shape so as to fix the end of the welding wire and facilitate auxiliary welding wire winding.

[0039] Among them, there are two fixing frames 501, and the two fixing frames 501 are relatively distributed, and the two fixing frames 501 are mutually clamped through the clamping block 504 and the clamping groove 503, so as to facilitate the disassembly of the inner tube 2 and the outer tube 3, and facilitate the winding of the welding wire and then installing it inside the reel frame 1.

[0040] Working principle: when in use, fix one end of the welding wire inside the wire fixing hole 29, then wind it on the surface of the outer cylinder 3, and wind the free end of the welding wire from the bottom of the pressure roller 10 upward through the rubber ring 15, and then pass through the two fixed wheels 2307 and extend outward. At this time, the elastic force of the compression spring 12 squeezes the pressure frame 8, and the pressure frame 8 squeezes the pressure roller 10 through the mounting shaft 9. The pressure roller 10 squeezes the surface and the free end of the welding wire roll to form a fixed position, thereby preventing the free end of the welding wire from spreading and loosening. When the welding wire is sheared, the pressure rod 21 is bent in the direction away from the outer cylinder 3. The pressure rod 21 rotates around the support shaft 20 and squeezes the guide block 25 through the pressure hole 22, so that the push frame 24 moves synchronously, thereby squeezing the movable cylinder 2301 to slide in the direction away from the outer cylinder 3. At the same time, the reset spring leaf 28 is squeezed and contracted. When the movable cylinder 2301 slides, it moves closer to the middle between the guide inclined holes 18. Since the limit spring leaf 2308 is tangential to the fixed wheel 2307 and meshes with the positioning groove 2309, The fixed wheel 2307 forms a one-way limit. At this time, the two fixed wheels 2307 squeeze and fix the welding wire. As the movable fixed wheel 2307 of the movable cylinder 2301 cannot be driven to rotate, the welding wire is pulled out until the pin 2304 slides to the end of the guide inclined hole 18. The two cutting teeth 2306 close and squeeze the welding wire, thereby cutting the welding wire. Then the pressure rod 21 is released, the reset spring 28 is reset and pushes the push frame 24 to return to the original path, thereby driving the movable cylinder 2301 to return and reset along the guide inclined hole 18, so that the cutting teeth 2306 separate immediately after cutting the welding wire, and the fixed wheel 2307 will squeeze the welding wire surface for a distance when resetting. When the fixed wheel 2307 is reset, the reset spring 28 has no limit on the reset rotation direction of the fixed wheel 2307, and the fixed wheel 2307 can roll freely on the surface of the welding wire, thereby avoiding the end of the welding wire from being pulled back until the movable cylinder 2301 returns to its original position. At this time, the end of the welding wire is exposed.
