DESCRIPTION OF THE INVENTION

[0021] The technical solutions in embodiments of the present disclosure are described clearly and completely below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by the person skilled in the art without creative labor shall fall within the protection scope of the present disclosure.

Embodiment 1

[0022] As shown in FIG. 1, there is provided a tool for a double-angle chamfering cutter, including a cutter handle 1 and a cutter body 2. The cutter handle 1 is connected to the cutter body 2 via a snap-fit device. FIG. 2 shows a partial schematic diagram of a cutter body 2 clamped into the cutter handle 1. One end of the cutter body 2 is provided with a sliding track 5 perpendicular to the cutter body. The sliding rail 5 and the side of the cutter body 2 form a cavity. A spring 8 is arranged inside the cavity. One end of the spring 8 is fixedly connected to the side of the cutter body 2, and the other end of the spring 8 is fixedly connected to a bump outside the cavity. The bump is fixedly connected to the sliding track 5. One aperture is provided inside the cutter handle 1. One side of the aperture is provided with a groove channel. The cutter body 2 enters along of the aperture inside the cutter handle 1. The bump on the cutter body 2 falls into the groove channel. The outer part of the cutter handle 1 has a square region. The square region is provided with one button 6. The inner part of the button 6 is connected to the top of the bump. When the cutter body 2 enters the cutter handle 1, the bump falls into the groove channel, and the cutter handle 1 and the cutter body 2 can be fixed. FIG. 3 shows a partial schematic diagram of a structure of a double-angle chamfering blade. FIG. 4 shows a cross-sectional diagram of a tool for a double-angle chamfering cutter. The end of the cutter body away from the cutter handle is provided with a chamfering blade A 3 and a chamfering blade B 4. The chamfering blade A 3 and the chamfering blade B 4 are at the corresponding positions on both sides of the cutter body 2. The chamfering blade A 3 and the chamfering blade B 4 are at 180 degrees. The chamfering blade A 3 and the chamfering blade B 4 are connected to the cutter body 2 via a locking screw 7, respectively. Two inclined ports are both provided on the chamfering blade A 3 and the chamfering blade B 4. An upper port forms an included angle of 30 degrees with the cutter body 2 in a vertical direction. The lower port forms an included angle of 60 degrees with the cutter body in a vertical direction.

Embodiment 2

[0023] This embodiment is distinct from Embodiment 1 in that a chamfering blade A and a chamfering blade B of this embodiment are fixed to a cutter body by welding, respectively. The chambering blade A and the chamfer blade B can be fixed and are not easily loosen by the welding, which is more beneficial to the fixation of the blade. The blade is not easy to move during a plurality of operations. However, inconvenience is that the surface of the blade body is easily damaged when the blade is replaced, and a process of removing the blade is complicated.

Embodiment 3

[0024] As shown in FIG. 3, a partial schematic diagram of a structure of a cutter body, this structure is a part of a cutter body that is clamped into a cutter handle. Embodiment 3 is distinct from Embodiment 1 in that a sliding track contains a folded sliding sheet instead of a rolling bead. The sliding sheet is fixedly connected to a bump. In the process of sliding, the expansion and contraction of the folded sliding sheet drives the bump to contract and expand. The stretchability of the sliding sheet is relatively good. The expected expansion and contraction effects can be achieved at the same time. The flexibility and the smoothness of the rolling bead are better than those of the sliding sheet. The best components can be selected according to the current price during a selection process.

[0025] Finally, it should be noted that the forgoing embodiments are only used to illustrate the technical solutions of the present disclosure and are not to limit thereto. Other modifications or equivalent substitutions made by the person skilled in the art to the technical solutions of the present disclosure shall fall in the scope of claims of the present disclosure without departing from the spirit and scope of the present disclosure.
