Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention. Embodiment 1

[0027] A preferred embodiment of the corner cutting machine with operation safety provided by the present invention is as Figures 1 to 5 shown: A corner cutting machine with operation safety includes a base 2. On one side of the top of the base 2, a fixed-length component 1 is provided. On the other side of the top of the base 2, a fixture 4 is fixedly connected. On the top of the base 2 on both sides of the fixture 4, a safety component 3 is provided. On the other side of the back of the base 2, a fixed frame 5 is fixedly connected. At one end of the top of the fixed frame 5, a lifting pneumatic telescopic rod 7 is fixedly connected. The output end of the lifting pneumatic telescopic rod 7 penetrates through the top of the fixed frame 5 and is fixedly connected to a sliding frame 8. On the back of the sliding frame 8, a corner cutting pneumatic telescopic rod 9 is fixedly connected. The output end of the corner cutting pneumatic telescopic rod 9 penetrates through one end of the sliding frame 8 and is fixedly connected to a mounting plate 6. At the bottom of the mounting plate 6, a corner cutting tool 10 is fixedly connected.

[0028] The safety component 3 includes a start switch 306. The start switch 306 is fixedly connected to the top of the base 2 on both sides of the fixture 4. On the top of the base 2 at one end of the start switch 306, a sliding groove 303 is opened. On both sides of the inner wall of the sliding groove 303, magnetic attraction blocks 304 are fixedly connected. Inside the sliding groove 303, a sliding block 302 is movably connected. On both sides of the sliding block 302, magnetic attraction holes 305 are opened. At the top of the sliding block 302, a protective frame 301 extending outside the sliding groove 303 is fixedly connected. By using the two start switches 306, it is necessary for the staff to press the start switches 306 with both hands at the same time to start the work of the lifting pneumatic telescopic rod 7 and the corner cutting pneumatic telescopic rod 9. Furthermore, it can avoid the safety hazards caused by the staff accidentally placing a hand on one side of the fixture 4 and directly performing corner cutting operations, making the operation of the staff safer.

[0029] In this embodiment, the cross-sectional shape of the protective frame 301 is an inverted L shape, and the protective frames 301 are symmetrically distributed about the vertical central axis of the fixed frame 5. By using the inverted L-shaped protective frame 301, it is convenient to shield and protect the start switch 306.

[0030] In this embodiment, a sliding structure is formed between the sliding block 302 and the inside of the sliding groove 303. The cross-sectional shapes of the sliding block 302 and the sliding groove 303 are convex. By using the sliding of the convex sliding block 302 inside the sliding groove 303, the smoothness of the sliding of the protective frame 301 is improved.

The cross-sectional shapes of the magnetic attraction block 304 and the magnetic attraction hole 305 are regular hexagons. By using the magnetic attraction engagement between the regular hexagon magnetic attraction block 304 and the interior of the magnetic attraction hole 305, the stability of the limit fixation after the sliding of the protective frame 301 and the sliding block 302 is improved. Embodiment 2

[0032] On the basis of Embodiment 1, a preferred embodiment of the corner cutting machine with safe operation provided by the present utility model is as Figures 1 to 5 shown: The fixed-length component 1 includes a fixed slot 101 which is opened at the middle position on one side of the top end of the base 2. The inner wall of the fixed slot 101 is rotatably connected with a threaded rod 102. One end of the threaded rod 102 is fixedly connected with a turning handle 106 extending outside the base 2. One end of the surface of the threaded rod 102 is threadedly connected with a threaded block 108. The top end of the threaded block 108 is fixedly connected with a fixed-length plate 104 extending outside the fixed slot 101. By rotating the turning handle 106 to drive the threaded rod 102 to rotate, the threaded block 108 slides to drive the fixed-length plate 104 to slide and drives the indicating block 109 to slide. At this time, the distance between the fixed-length plate 104 and the fixture 4 can be accurately known by using the scale value 103, so that the corner cutting distance is fixed after the workpiece passes through the fixture 4, and thus the fixed-length corner cutting action of the workpiece can be realized.

[0033] In this embodiment, sliding grooves 105 are opened at the top ends of the base 2 at both ends of the fixed slot 101. Both ends of the bottom end of the fixed-length plate 104 are fixedly connected with sliders 107 which are slidably matched with the interiors of the sliding grooves 105. By using the sliding of the sliders 107 in the sliding grooves 105, the smoothness of the sliding of the fixed-length plate 104 is improved.

[0034] In this embodiment, an indicating block 109 is fixedly connected to the lower end of the front surface of the fixed-length plate 104. A scale value 103 is opened on one side of the top end of the base 2 at one end of the fixed-length plate 104. By using the cooperation of the scale value 103 and the indicating block 109, it is convenient for the staff to clearly know the sliding distance of the fixed-length plate 104.

[0035] In addition, a limiting groove 11 is opened on the inner top wall of the sliding frame 8. The top end of the mounting plate 6 is fixedly connected with a limiting block 12 which is slidably matched with the interior of the limiting groove 11. By using the sliding of the limiting block 12 in the limiting groove 11, the smoothness of the sliding of the mounting plate 6 is improved.

[0036] The working principle and usage process of the present utility model: First, rotate the turning handle 106 to drive the threaded rod 102 to rotate. By using the threaded cooperation between the threaded rod 102 and the threaded block 108, the threaded block 108 slides to drive the fixed-length plate 104 to slide and drives the indicating block 109 to slide. At this time, the distance between the fixed-length plate 104 and the fixture 4 can be accurately known by using the scale value 103, and thus the fixed-length corner cutting action of the workpiece can be realized;

[0037] After that, the workpiece is passed through the fixture 4, and one end of the workpiece is abutted against one side of the fixed-length plate 104. After that, the protective frame 301 can be pushed, so that the sliding block 302 slides inside the sliding groove 303, and then the magnetic attraction hole 305 at one end of the sliding block 302 and the magnetic attraction block 304 at one end of the sliding groove 303 are magnetically engaged to realize the limit fixation after the sliding of the sliding block 302, and then the start switch 306 can be completely exposed;

[0038] Then when chamfering the workpiece, the operator must press the start switch 306 with both hands at the same time to start the operation of the lifting pneumatic telescopic rod 7 and the chamfering pneumatic telescopic rod 9. At this time, the lifting pneumatic telescopic rod 7 works to drive the sliding frame 8 to descend to an appropriate height, and then the chamfering pneumatic telescopic rod 9 is started to make the mounting plate 6 slide, so that the chamfering cutter 10 slides to chamfer the workpiece, which is convenient for bending the workpiece into a rectangle. At the same time, pressing the start switch 306 with both hands can avoid the safety hazard caused by the operator accidentally placing a hand on one side of the fixture 4 and directly performing the chamfering operation. When not in use, the magnetic attraction engagement inside another set of magnetic attraction blocks 304 and magnetic attraction holes 305 is used to realize the shielding and protection of the start switch 306 after the sliding of the protective frame 301, and avoid the inconvenience of operation caused by accidentally touching the start switch 306.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
