[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 and Figure 2This utility model provides a technical solution: a handheld threader with adjustable wire diameter, comprising a frame assembled from a base 1 and a cover plate 2. The base 1 and the cover plate 2 are fixedly connected by several screws. A wire outlet tube 3 and a wire inlet tube 4 for threading are coaxially fixed through both sides of the base 1. The outer wall of the wire inlet tube 4 is fitted with a rubber sleeve. The advantage of this design is to improve the comfort of the user holding the wire inlet tube 4. It also includes a pair of guide wheel assemblies movably disposed in the frame. One of the guide wheel assemblies is slidably installed in the frame through an elastic member. The top and bottom of the frame are respectively provided with sliding holes for the guide wheel assemblies to slide, so as to adjust the spacing between the pair of guide wheel assemblies according to the wire diameter. When using this device, it needs to be connected to an electric wrench. The drive end of the electric wrench is connected to one of the guide wheel assemblies to drive the guide wheel assembly to rotate and thread the wire.

[0022] Please see Figure 3 and Figure 4 The guide wheel assembly consists of a rotating shaft, rubber wheels 6, a pair of bearings 7, and hexagonal nuts 8. An electric wrench is connected to the hexagonal nuts 8 via an internal hexagonal socket (existing technology) to drive the guide wheel assembly to rotate. The sidewall of the rubber wheel 6 is designed with an arc shape to conform to the wire, thereby increasing the contact area between the rubber wheel 6 and the wire. A wire-passing cavity is formed between the pair of rubber wheels 6 to accommodate the wire. The rotating shaft of one guide wheel assembly is rotatably connected to the frame, while a bracket 9 is fitted onto the rotating shaft of the other guide wheel assembly. Guide plates 5 are fixedly installed on the inner walls of the top and bottom of the frame, respectively. One end of the guide plate 5 has a groove for accommodating the bracket 9. The purpose of this arrangement is to facilitate the limiting of the bracket 9. The elastic component is connected to the bracket 9. A pair of wing bolts 10 are fixedly installed on one side of the bracket 9. The other end of the wing bolts 10 penetrates the side wall of the base 1 and is sleeved with the same pull plate 12. The pull plate 12 is integrally formed into a U-shaped structure and has a pair of through holes. The pull plate 12 provides a handle for adjusting the guide wheel assembly. The through holes facilitate pulling the pull plate 12 and driving the guide wheel assembly to slide. The elastic component is a spring 11 sleeved on the wing bolts 10. The wing bolts 10 are fitted with anti-detachment caps 13 between the base 1 and the bracket 9. The two ends of the spring 11 are in contact with the anti-detachment caps 13 and the bracket 9, respectively. During threading, pulling the pull plate 12 causes the wing bolt 10 to extend outward, widening the gap between the pair of guide wheel assemblies caused by the bracket 9. The wire is then threaded through the inlet pipe 4 into the frame, passing between the pair of rubber wheels 6 before exiting through the outlet pipe 3. Releasing the pull plate 12 releases the elastic potential energy of the spring 11, causing the rubber wheels 6 to fit tightly against the wire. An electric wrench can then be used to rotate the guide wheel assembly, which is connected to the cover plate 2, for threading. This application, through the cooperation of the bracket 9, wing bolt 10, spring 11, and pull plate 12, allows the pair of guide wheel assemblies to adaptively adjust their spacing according to the wire diameter. The structure is simple and easy to operate, shortening the threading preparation time compared to the current method of adjusting the spacing by turning, and effectively improving threading efficiency.
