[0007] In some embodiments, the opening groove is provided on both sides of the mounting seat, and the impact column is in contact with the groove surface of the opening groove and the shell.

[0008] In some embodiments, the limiting plate is triangular, and at least a portion thereof contacts the spring.

[0009] In some embodiments, the cutter is formed at the bottom of the impact column and is fitted with the housing.

[0010] In some embodiments, the positioning protrusion extends downward from the housing and forms a triangular positioning portion with the mounting seat.

[0011] In some embodiments, the triangular positioning parts are respectively located on both sides of the mounting base.

[0012] In some embodiments, a right-angle positioning portion is formed between the positioning protrusion and the housing.

[0013] In some embodiments, a mounting positioning plate for cooperating with the shell is formed on the mounting seat.

[0014] In some embodiments, the top of the impact column is processed into a curved surface.

[0015] The beneficial effect of the present application is that by striking the impact columns on both sides of the mounting seat, a right-angle groove can be quickly chiseled, especially for a groove of a specific length, which is more efficient. The right-angle positioning part and the triangular positioning part formed by the positioning protrusions at the bottom are adapted to the support and positioning of the punching tool in grooves of different sizes. When it is a small groove, it is supported on the groove wall by the right-angle positioning part, and the large groove is supported by the triangular positioning part, which has good applicability and high chiseling efficiency.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection of this application.

[0022] In the examples of this application, please refer to Figure 1-3As shown, the punching tool mainly includes: a mounting base 1, on which a shell 2 is fixed, a pair of symmetrically arranged opening grooves 3 are provided on the mounting base 1, a receiving hole 4 is provided at the bottom of the opening groove 3, and a spring 5 is placed in the receiving hole 4; an impact column 6 slides in the opening groove 3, a limit plate 601 is formed in the middle thereof, the limit plate 601 is in contact with the upper end of the spring 5, and a tool 602 is provided at the bottom of the impact column 6; a positioning protrusion 101 is formed at the bottom of the mounting base 1 for auxiliary positioning; knocking the impact column 6 can drive the tool 602 to cut a right-angle groove downward.

[0023] Some preferred / improved embodiments based on the above embodiments will be described below. Any one of the following embodiments may be selected, or multiple embodiments may be selected and combined.

[0024] like Figure 1 、 Figure 3 As shown, the opening groove 3 is opened on both sides of the mounting seat 1, and the impact column 6 is in contact with the groove surface of the opening groove 3 and the shell 2. The impact column 6 slides in the opening groove 3, is wrapped by the shell 2, and will not completely separate from the opening groove 3.

[0025] Furthermore, the limiting plate 601 is triangular, and at least a portion thereof contacts the spring 5, and is used to compress the spring 5 when striking the impact column 6. At the same time, the restoring force of the spring 5 is also fed back to the impact column 6 through the limiting plate 601. The limiting column is also used to cooperate with the shell 2, and when the spring 5 recovers, it clamps the impact column 6 so that it does not leave the opening slot 3.

[0026] Specifically, the tool 602 is formed at the bottom of the impact column 6 and is fitted with the housing 2 . The tool 602 is formed at a right angle to facilitate the excavation of a right-angle groove.

[0027] like Figure 2 As shown, the positioning protrusion 101 extends downward from the shell 2 and forms a triangular positioning portion 7 with the mounting base 1. The triangular positioning portion 7 is used to open a right-angle groove on a larger groove. The triangular positioning portion 7 on the positioning protrusion 101 is pressed against the edge of the arc-shaped groove (or other non-right-angle groove) and is chiseled multiple times until a complete right-angle groove is chiseled out.

[0028] Specifically, the triangular positioning parts 7 are respectively located on both sides of the mounting base 1 and close to the location of the tool 602.

[0029] Furthermore, a right-angle positioning portion 8 is formed between the positioning protrusion 101 and the shell 2. When in use, the right-angle positioning portion 8 is placed against the side wall of the groove, and the impact column 6 on one side is close to the end of the groove. The impact column 6 is knocked to open the right-angle groove. If the groove is of a specific length, the opening position of two right-angle grooves can be located at one time, and the opening of the right-angle groove can be completed by knocking the two impact columns 6 separately.

[0030] Specifically, a mounting positioning plate 102 for cooperating with the housing 2 is formed on the mounting seat 1 .

[0031] Furthermore, the top of the impact column 6 is processed into a curved surface to make it more beautiful.
