When grinding the hardware parts, first fix the mounting frame 1 on the workbench through the mounting holes 11, then sleeve the sandpaper 15 on the driving wheel 13 and the driven wheel 14, and start the motor 12 to drive the driving wheel 13 to rotate, and then drive the rotation of the driven wheel 14 through the connection of the sandpaper 15 to realize the normal operation of the sandpaper 15;

[0027] A handheld mechanism, including a pull rod 2, the pull rod 2 is arranged on the surface of the mounting frame 1, a connecting plate 21 is fixedly connected to the surface of the pull rod 2, a first connection hole 22 is opened on the surface of the connecting plate 21, a second connection hole 23 is opened on the surface of the mounting frame 1, a bolt 24 is arranged on the surface of the second connection hole 23, and a nut 25 is installed on the surface of the bolt 24. The cross-section of the connecting plate 21 is in an "L" shape, and the connection between the pull rod 2 and the mounting frame 1 can be realized through the setting of the connecting plate 21.

[0028] Further, there are two sets of pull rods 2, which are arranged on both sides of the mounting frame 1. The cross-section of the pull rod 2 is in a "C" shape. The two ends of the pull rod 2 are fixedly connected to the surface of the connecting plate 21. There are two sets of first connection holes 22 and second connection holes 23. The pull rod 2 can provide a grip for the operator to hold the pull rod 2 and turn the grinding machine to grind the hardware.

[0029] Further, the diameters of the first connection hole 22 and the second connection hole 23 are the same. One end of the bolt 24 is abutted and connected to the surface of the mounting frame 1, and the other end of the bolt 24 is threadedly connected to the surface of the nut 25. The size of the nut 25 is larger than the size of the first connection hole 22. The nut 25 is abutted and connected to the surface of the connecting plate 21. The bolt 24 passes through and connects the mounting frame 1 and the connecting plate 21 through the first connection hole 22 and the second connection hole 23. Under the connection of the bolt 24 and the nut 25, the connecting plate 21 can be installed on the mounting frame 1, and at the same time, it is also convenient for the disassembly and assembly of the pull rod 2 and the connecting plate 21.

[0030] Further, a protection mechanism is arranged on the surface of the sandpaper 15. The protection mechanism includes a guard plate 3. The guard plate 3 is movably connected to the surface of the sandpaper 15. A limiting groove 31 is opened on the surface of the guard plate 3. A rotating rod 32 is fixedly connected to the surface of the guard plate 3. A first mounting block 33 and a second mounting block 35 are fixedly connected to the surface of the mounting frame 1. An installation groove 34 is opened on the surface of the first mounting block 33. A rotating groove 36 is opened on the surface of the second mounting block 35. A rotating plate 37 is movably connected to the surface of the mounting frame 1. A rotating block 38 and a limiting plate 39 are fixedly connected to the surface of the rotating plate 37. When the guard plate 3 is installed above the sandpaper 15, the scratching between the operator and the sandpaper 15 can be reduced, and thus the injury situation when not in use can be reduced.

[0031] Further, there are two sets of the rotating rod 32 and the first mounting block 33. The two sets of rotating rods 32 are fixedly connected to the surface of the guard plate 3. The two sets of first mounting blocks 33 are arranged on both sides of the guard plate 3. The rotating rod 32 is movably connected to the surface of the installation groove 34. There are two sets of second mounting blocks 35. The two sets of second mounting blocks 35 are arranged on both sides of the rotating plate 37. The guard plate 3 can be disassembled and assembled along the surface of the installation groove 34 through the rotating rod 32, preventing the setting of the guard plate 3 from blocking the grinding of the hardware during use.

[0032] Further, one side of the rotating plate 37 is movably connected to the surface of the second mounting block 35, and the other side of the rotating plate 37 is abutted and connected to the surface of the guard plate 3. The rotating block 38 is rotatably connected to the surface of the rotating groove 36. The rotating plate 37 can rotate through the rotating groove 36 with the rotating block 38 as the center, and the rotating groove 36 and the rotating block 38 perform damped rotation.

[0033] Further, two sets of rotating blocks 38 are fixedly connected to both sides of the rotating plate 37. One side of the limiting plate 39 is fixedly connected to the surface of the rotating plate 37, and the other side of the limiting plate 39 is inserted and connected to the surface of the limiting groove 31. Under the connection action of the limiting plate 39 and the limiting groove 31, the limiting of the guard plate 3 is realized to avoid the shaking of the guard plate 3 during movement. Moreover, under the abutment of the rotating plate 37 and the guard plate 3, the rotating plate 37 supports the guard plate 3, so that the guard plate 3 is placed above the sandpaper 15 and does not contact it.

[0034] Working principle: When the grinding machine grinds large or heavy hardware parts, the mounting frame 1 can be removed from the workbench through the mounting holes 11. Align the first connection holes 22 and the second connection holes 23 opened on the two connecting plates 21, and insert one end of the bolt 24 into the second connection hole 23 and the first connection hole 22 in sequence. Under the action of the thread, install the nut 25 on the bolt 24 so that the nut 25 abuts against the connecting plate 21 to fix the connecting plate 21. The operator can hold the two pull rods 2 with both hands and turn them over, and then start the motor 12 for grinding.

[0035] When the grinding machine is not in use, slide the rotating rods 32 fixed on both sides of the guard plate 3 along the mounting groove 34 to the innermost part of the mounting groove 34, and then rotate the rotating plate 37 through the rotating groove 36 with the rotating block 38 as the center, so that the limiting plate 39 is placed upward. At this time, rotate the guard plate 3 with the rotating rod 32 as the center, so that the guard plate 3 rotates above the sandpaper 15, so that the limiting plate 39 is inserted into the surface of the limiting groove 31, and the rotating plate 37 abuts against the inner surface of the guard plate 3 to complete the covering of the sandpaper 15.

[0036] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention. Any reference signs in the claims should not be regarded as limiting the claimed rights.
