[0017] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0018] like Figure 1 , Figure 2 As shown, the novel tap comprises a tap body 1 and a tap head 2, wherein the tap body 1 and the tap head 2 are detachable split structures, a plug-in column 4 for quick plug-in connection is arranged at the end of the tap head 2, a connecting groove 3 for plugging the plug-in column 4 is arranged at the end of the tap body 1, a plurality of movable parts 6 for guiding connection and fixing are movably arranged on the side wall of the connecting groove 3, a plurality of guide grooves 5 for guiding connection of the corresponding movable parts 6 are arranged on the peripheral wall of the plug-in column 4, a connecting hole 7 for limiting and fixing the corresponding movable parts 6 is arranged at the end of the guide groove 5, the movable part 6 fixes and disassembles the tap body 1 and the tap head 2 by a fastening screw 8, the structural design is simple, and the detachable split structure is arranged, which can effectively reduce the overall scrapping of the tap caused by chipping, reduce the use cost of the tap, and can replace a variety of tap heads 2 according to actual conditions, and has a wide range of applications.

[0019] How it works

[0020] The novel tap changes the traditional one-piece structure design of taps, and improves it into a split structure consisting of a tap head 2 and a tap body 1. Even if the tap head 2 breaks, there is no need to disassemble the entire tap, and only the tap head 2 needs to be disassembled and replaced to carry out processing. After replacing the tap head 2, processing can be carried out directly, and there is no need to calibrate after replacing the tap as in the traditional way. Moreover, a variety of tap heads 2 can be replaced according to actual conditions, which greatly improves processing efficiency and reduces the cost of tap damage. At the same time, a guide groove 5 and a movable part 6 structure are provided, which can effectively facilitate the rapid insertion and fixation of the tap head 2 and the tap body 1, and the connection strength is high and not easy to loosen.

[0021] To further elaborate, in order to achieve a stable connection between the movable part 6 and the tap head 2 and to improve the connection strength between the movable part 6 and the fastening screw 8, the movable part 6 and the fastening screw 8 are integrally formed and located at the end of the fastening screw 8, and the movable part 6 and the connecting hole 7 are axially plug-fitted.

[0022] To further elaborate, in order to achieve plug-in guidance and stable connection, a plurality of guide grooves 5 are arranged on the peripheral wall of the plug-in column 4 in a spiral structure, and the number of the guide grooves 5 is equal to the number of the movable parts 6, both of which are 3.

[0023] Preferably, a connecting boss 9 is axially extended outward from the end of the tap body 1 for easy plug-in connection, the connecting groove 3 passes through the connecting boss 9, and the outer diameter of the connecting boss 9 is equal to the outer diameter of the tap head 2. The connecting boss 9 and the tap body 1 are an integrally formed structure, and the tap body 1 is a rectangular structure.

[0024] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0025] Although the terms such as tap body 1, tap head 2, connection groove 3, plug-in column 4, guide groove 5, movable part 6, connection hole 7, fastening screw 8, connection boss 9 are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
