[0026] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0027] Combination Figure 1-5 As shown, a corner cleaner comprises a shell 1 and a cutter head 2, wherein the cutter head 2 is a rectangular parallelepiped, and the four faces of the cutter head 2 except the top face and the bottom face are named as the first face 3, the second face 4, the third face 5 and the fourth face 6 respectively, and the top of the cutter head 2 is provided with a first triangular pyramid-shaped groove body 7, and the end angle of the bottom of the first groove body 7 overlaps with the upper end of the intersection of the first face 3 and the second face 4 of the cutter head 2, and the lower end of the cutter head 2 is provided with a second groove body 8 in an "L" shape, and the second groove body 8 is arranged at the lower end of the intersection of the first face 3 and the second face 4 of the cutter head 2, and the bottom of the second groove body 8 extends to the bottom end of the cutter head 2;

[0028] The shell 1 has a mounting groove corresponding to the cutter head 2, and the cutter head 2 is telescopically connected to the shell 1. The four surfaces of the upper end of the cutter head 2 are respectively abutted against the four walls in the mounting groove. A spring 9 is provided between the first slot body 7 and the top of the shell 1. The lower end of the cutter head 2 extends out of the bottom of the shell 1. The bottom of the shell 1 has an opening corresponding to the lower end of the cutter head 2. A limiting portion corresponding to the second slot body 8 is provided at the opening. The top wall of the second slot body 8 abuts against the limiting portion to limit the stroke of the cutter head 2.

[0029] In the above structure, the first slot body 7 is designed to be in the shape of a triangular pyramid, the purpose of which is that on the one hand, a spring 9 with a larger elastic coefficient can be placed to provide sufficient support for the cutter head 2, and the rigidity of the upper end of the cutter head 2 will not be reduced too much, so that the upper end of the cutter head 2 on one side of the first slot body 7 maintains a certain thickness; on the other hand, one end of the spring 9 is inserted into the first slot body 7, which can save installation space and make the entire device structure more compact. In addition, springs 9 with different outer diameters are inserted into the first slot body 7 to different depths, so that the cutter head 2 can obtain different retraction strokes, and the depth is easy to control.

[0030] The entire cutter head 2 is designed as a rectangular parallelepiped, and the edge at the lower end of the cutter head 2 is the blade, which pushes the shell 1 to slide along the edge of the fixed groove of the corresponding lock or hinge, and can perform corner cleaning on the inner angles of the fixed groove, and the original arc chamfer can be processed into a right angle, and the burrs on the inner edge of the fixed groove can be removed; the four walls of the cutter head 2 are in contact with the four walls of the installation groove, and the installation groove provides better support for the cutter head 2. At the same time, the installation groove also plays a guiding role, so that the cutter head 2 is not easy to shake, and the overall structure is more stable.

[0031] The working principle of the above structure is: combined with Figure 6 and Figure 7 As shown, the above-mentioned corner cleaner can be hand-held or assembled on corresponding equipment for use. When working, the blade head 2 of the corner cleaner is inserted into the fixed groove of the corresponding lock or hinge, and the edge of the blade head 2 is abutted against the edge of the inner side of the fixed groove; since the blade head 2 is retractable, the above-mentioned device can adapt to the corner cleaning of fixed grooves of different depths; the shell 1 is pushed to slide along the edge in the fixed groove, and the blade head 2 cleans the inner angles of the fixed groove, and the original arc chamfer is processed into a right angle, so that the lock or hinge is easy to install, and the combination of the lock or hinge and the fixed groove is tighter and firmer, and there is no gap between the two.

[0032] Preferably, two cutter heads 2 are provided on the housing 1. Since the fixing grooves of the corresponding locks or hinges are generally divided into a plurality of fixed standard sizes, a corner cleaner equipped with two cutter heads 2 can clean the four inner corners more quickly.

[0033] Specifically, the two cutter heads 2 are symmetrically arranged on both sides of the housing 1 .

[0034] In another embodiment, in combination Figure 1 and Figure 2 As shown, the housing 1 is composed of a main body 10, two side plates 11, a back plate 12 and a bottom plate 13. The main body 10 is provided with grooves corresponding to the cutter head 2 and the spring 9. The two side plates 11 and the back plate 12 are respectively fixed on the housing 1 so that the grooves form mounting grooves. A trapezoidal notch 14 is respectively provided at the two end corners of the bottom plate 13. The bottom plate 13 is fixed to the bottom of the housing 1 so that the trapezoidal notch 14 forms an opening corresponding to the lower end of the cutter head 2 and a limiting portion corresponding to the second slot body 8.

[0035] The above structure makes the structure of the entire housing 1 stable, reliable and simple, and also facilitates the assembly of the housing 1, the cutter head 2 and the spring 9.

[0036] In another embodiment, in combination Figure 1-4 As shown, corresponding screw holes are provided on the two side plates 11, the back plate 12, the bottom plate 13 and the housing 1, and the two side plates 11, the back plate 12 and the bottom plate 13 are fixed to the housing 1 by screws respectively.

[0037] In another embodiment, if Figure 5 As shown, the three inner corners at the top of the first slot body 7 are spaced apart from the three corners at the top of the cutter head 2 .

[0038] In another embodiment, in combination Figure 1-5 As shown, the bottom of the cutter head 2 also has an arc chamfer, so that the cutter head 2 can be inserted into the fixing groove of the corresponding lock or hinge, and at the same time, the sharp end corners of the cutter head 2 can be prevented from causing damage to external objects during carrying.

[0039] In another embodiment, in combination Figure 1-3 As shown, a protruding connection portion 15 is also provided on the top of the housing 1, and the connection portion 15 is used to install and fix the angle cleaner to the interface of the corresponding device.

[0040] In another embodiment, as shown in FIG. 3 , the connecting portion 15 is arrow-shaped, the front end of the connecting portion 15 is a flat angle, and the connecting portion 15 and the shell 1 are an integrally formed structure.
