[0030] When it is necessary to cut the hardware, the blade 17 is moved to the cutting position, and then the grinding sheet 3 and the blade 17 are rotated. At this time, the blade 17 is moved downward so that the blade 17 can cut the hardware. After the cutting is completed, the blade 17 continues to move downward. At this time, the grinding sheet 3 is able to contact the cutting surface of the hardware, so that the grinding sheet 3 can grind the cutting surface of the hardware, so that no burrs are generated on the cutting surface, and there is no need for additional subsequent grinding and polishing, thereby reducing the processing time of the hardware and improving the processing efficiency.

[0033] When the grinding sheet 3 needs to be installed, the insertion rod 4 is slid into the interior of the connecting shaft 2, and then the hollow rod 5 is slid into the interior of the placement groove 7, and the placement groove 7 passes through the insertion rod 4. At this time, when the rear side of the pull block 9 fits with the front side of the placement groove 7, the threaded rod 6 is screwed into the interior of the hollow rod 5. When the turntable 8 fits with the rear side of the placement groove 7, the insertion rod 4 can be stably installed in the interior of the connecting shaft 2, thereby making the installation of the grinding sheet 3 more stable. Otherwise, the grinding sheet 3 can be conveniently disassembled.

[0034] Embodiment 3

[0035] On the basis of the second embodiment, in order to achieve a more stable installation of the blade 17, a plurality of slots 16 are provided on the inner side of the blade 17, a plurality of grooves are provided inside the slots 16, a plurality of mounting slots 10 are provided inside the right side of the grinding disc 3, a plurality of limit blocks 11 are fixedly connected to the inner wall of the mounting slot 10, the limit blocks 11 are designed in a right-angled triangle, and the lower side is designed in a circular arc, a mounting block 12 is slidably connected to the inside of the mounting slot 10, the mounting slot 10 limits the mounting block 12, so that the mounting block 12 does not shake, a plurality of limit blocks 2 13 are fixedly connected to the upper and lower sides of the mounting block 12, the limit blocks 11 match the limit blocks 2 13, the limit blocks 11 and the limit blocks 2 13 are engaged, and the engagement position The second limit block 13 is designed as a right triangle, and the upper side is designed as an arc, so that the mounting block 12 can easily slide into the interior of the mounting groove 10. The middle parts of the upper and lower sides of the mounting block 12 are fixedly connected with a clamping block 14, and the clamping groove 16 matches the clamping block 14. The side of the clamping block 14 away from the mounting block 12 is designed as an arc, so that the mounting block 12 can easily slide into the interior of the mounting groove 10. The outside of the clamping block 14 is fixedly connected with a plurality of rubber rings 15, and the outside of the rubber ring 15 fits with the inner groove of the clamping groove 16, so that the friction between the clamping block 14 and the clamping groove 16 is greater, so that the clamping groove 16 will not easily detach from the inside of the blade 17, and the blade 17 can cut the hardware normally.

[0036] When the blade 17 needs to be installed on the grinding sheet 3, the blade 17 is moved to the right, so that the mounting block 12 can enter the interior of the mounting groove 10. In this process, the inclined surfaces of the limit block 11 and the limit block 2 13 slide against each other and deform against each other, and the arc of the clamping block 14 also slides inside the mounting groove 10 and is squeezed and deformed by the mounting groove 10.

[0039] In actual use, the blade 17 is first moved to the right, so that the mounting block 12 can enter the interior of the mounting groove 10. During this process, the inclined surfaces of the limit block 11 and the limit block 2 13 slide against each other and deform against each other, and the arc of the clamping block 14 also slides inside the mounting groove 10 and is squeezed and deformed by the mounting groove 10. When the mounting block 12 fits against the left side of the inner wall of the mounting groove 10, the inclined surfaces of the limit block 2 13 and the limit block 1 11 will separate from each other, and their straight The two corners are located at the same position, so that the limit block 13 and the limit block 11 can both perform a reset movement, so that the right angles can be engaged, and at the same time, the card block 14 and the card slot 16 are kept on the same horizontal line, so that the card block 14 can perform a reset movement, so that the card block 14 can enter the inside of the card slot 16.
