[0027] To make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them.

[0028] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed invention, but merely represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0030] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0031] like Figure 1-5 As shown, this embodiment provides a hand drill adapter for quickly clamping thin metal wires, including an adapter handle 1, and a clamping mechanism 2 is provided on one side of the adapter handle 1.

[0032] like Figure 3As shown, the clamping mechanism 2 includes a clamping portion 201, a clamping groove 202, a clamping tube 203, a protective tube 204, a spring 205, a limiting plate 206 and an adapter groove 207. The clamping portion 201 is fixedly connected to the side wall of the adapter handle 1. The clamping groove 202 is opened at the end of the clamping portion 201 away from the adapter handle 1. The clamping tube 203 is slidably connected to the outside of the adapter handle 1. The protective tube 204 is fixedly connected to the outside of the clamping tube 203. The spring 205 is fixedly connected to the outside of the clamping tube 203. 5 is arranged on the outside of the adapter handle 1, the limiting plate 206 is fixedly connected to the outer wall of the adapter handle 1, the adapter groove 207 is opened on the outer wall of the adapter handle 1, the two ends of the spring 205 are respectively fixedly connected to the side wall of the limiting plate 206 and the side wall of the clamping tube 203, the number of the clamping parts 201 is three and they are distributed along the circumference of the central axis of the clamping part 201, one end of the clamping tube 203 is tightly fitted with the outer walls of the three clamping parts 201, and the protective tube 204 is fixed to the outer wall of the three clamping parts 201. The adapter handle 1 is slidably connected, and the other end of the spring 205 is fixedly connected to the limiting plate 206. The outer wall of the limiting plate 206 fits tightly against the interior of the protective tube 204. The adapter groove 207 is located on the end of the adapter handle 1 away from the clamping part 201. When in use, the adapter handle 1 is inserted into the external electric drill connector, and then the drill chuck of the electric drill is rotated to fix the adapter handle 1. When it is necessary to clamp the fine metal wire, the protective tube 204 is moved to the side close to the adapter groove 207, and then the clamping tube 203 is moved along with it. At this time, the spring 205 contracts. When the clamping tube 203 is completely separated from the clamping part 201, the clamping part 201 loses its restriction. Then the fine metal wire is placed inside the groove body surrounded by the three clamping grooves 202, and then the protective tube 204 is loosened, so that the spring 205 drives the clamping tube 203 to move in the direction close to the clamping part 201, thereby fixing the clamping part 201 and clamping the metal wire.

[0033] like Figure 5 As shown, transverse grooves 3 and anti-slip grooves 4 are respectively provided on the outer wall of the protective tube 204. There are several transverse grooves 3 and they are distributed circumferentially along the central axis of the protective tube 204. There are several anti-slip grooves 4 and they are evenly distributed along the length direction of the protective tube 204. When in use, the staggered arrangement of the transverse grooves 3 and the anti-slip grooves 4 can greatly improve the anti-slip effect of the protective tube 204, making it convenient for the user to move the protective tube 204.

[0034] like Figure 4 As shown, a crash pad 5 is fixedly connected to the side wall of the protective tube 204. There are several crash pads 5 distributed circumferentially along the central axis of the protective tube 204. When the protective tube 204 moves to one side, the crash pad 5 can prevent the protective tube 204 from colliding with the electric drill, thereby increasing the service life of the device.

[0035] like Figure 1As shown, an anti-corrosion layer is provided on the outer wall of the protective tube 204, and the anti-corrosion layer is a galvanized layer. When used, the anti-corrosion layer made of the galvanized layer can improve the corrosion resistance and hardness of the protective tube 204, and at the same time can also improve the aesthetics of the device.

[0036] like Figure 1 As shown, an anti-wear layer is provided on the outer wall of the adapter handle 1, and the anti-wear layer is a titanium nitride layer. When used, the anti-wear layer made of titanium nitride has the characteristics of high hardness and good wear resistance. It can significantly improve the wear resistance and hardness of the adapter handle 1, thereby reducing the wear rate of the adapter handle 1.

[0037] like Figure 1 As shown, a lower pressure plate 6 is fixedly connected to the side wall of the protective tube 204 near the clamping portion 201. The lower pressure plate 6 is made of plastic. When the user holds the protective tube 204 with his hand to move the protective tube 204, the user can press his thumb on the lower pressure plate 6 to prevent the palm from slipping.

[0038] like Figure 3 As shown, the material of the spring 205 is stainless steel. When the device is used for a long time, the stainless steel spring 205 can avoid rusting, thereby increasing the service life of the spring 205.

[0039] Specifically, when using this hand drill adapter for quickly clamping thin metal wires: insert the adapter handle 1 into the external electric drill connector, then rotate the drill chuck of the electric drill to fix the adapter handle 1. When the thin metal wire needs to be clamped, move the protective tube 204 to the side close to the adapter groove 207. The staggered arrangement of the transverse grooves 3 and the anti-slip grooves 4 can greatly improve the anti-slip effect of the protective tube 204. Then the clamping tube 203 also moves. At this time, the spring 205 contracts. When the clamping tube 203 is completely separated from the clamping part 201, the clamping part 201 loses its restriction. Then place the thin metal wire inside the groove body surrounded by the three clamping grooves 202, and then loosen the protective tube 204, so that the spring 205 drives the clamping tube 203 to move in the direction close to the clamping part 201, thereby fixing the clamping part 201 and clamping the metal wire.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
