[0028] The auxiliary mechanism 4 includes a first fixed block 402, two second fixed blocks 404 are connected to the bottom of the first fixed block 402, a slide groove 412 is provided at the bottom of the second fixed block 404, a first extrusion block 408 is slidably connected to the inner wall of the slide groove 412, a first pulley 407 is connected to the bottom of the first extrusion block 408, a sliding groove is provided on one side of the inner wall of the slide groove 412, and a second extrusion block 409 is slidably connected to the inner wall of the sliding groove, one side of the second extrusion block 409 is in contact with one side of the first extrusion block 408, and the other side of the second extrusion block 409 is in contact with the first extrusion block 408.

[0029] The specific implementation method is as follows: by setting the auxiliary mechanism 4, the handle 3 drives the angle grinder body 2 to move downward, and the angle grinder body 2 moves downward to drive the fixed box 501 to move downward, and the fixed box 501 drives the two threaded blocks 504 to move downward through the internal bidirectional threaded rod 503, and the threaded block 504 drives the two third springs 505 connected to the third fixing plate 506 to move downward through the third fixing plate 506, and the third spring 505 drives the two second fixing blocks 404 connected to the first fixing block 402 to move downward through the first fixing block 402, and the second fixing block 404 drives the first fixing plate 406 to move downward through the second spring 405, and the first fixing plate 406 moves downward to drive the first extrusion block 408 and the first pulley 407 to move downward, so that the first pulley 407 contacts the ground. Since the elastic force of each third spring 505 is greater than the elastic force of one first spring 403 plus one second spring 405, This first pulley 407 can drive the first extrusion block 408 upward in the slide groove 412 through the extrusion of the ground, and at the same time can drive the second spring 405 to be compressed through the first fixed plate 406. The upward movement of the first extrusion block 408 can squeeze one side of the second extrusion block 409. Since the sides where the first extrusion block 408 and the second extrusion block 409 are squeezed are both inclined surfaces, the second extrusion block 409 can move out of the sliding groove and can drive the first spring 403 to stretch through the second fixed plate 410. The second extrusion block 409 moves out of the sliding groove and drives the second pulley 411 to contact the side of the iron block 1, so that the iron block 1 can be positioned, so that the angle grinder body 2 can move along the iron block 1 without deviation, thereby improving the grinding effect and avoiding the need to readjust the position of the angle grinder due to deviation during the grinding process, saving grinding time and improving grinding work efficiency.

[0030] The adjusting mechanism 5 includes a fixed box 501, the bottom of the fixed box 501 is connected to the top of the angle grinder body 2, the inner wall of the fixed box 501 is rotatably connected to a bidirectional threaded rod 503, one side of the fixed box 501 is connected to a motor 502, the output shaft of the motor 502 extends into the fixed box 501 and is connected to one end of the bidirectional threaded rod 503, the outer wall of the bidirectional threaded rod 503 is threadedly connected to two threaded blocks 504, the outer wall of the threaded block 504 is slidably connected to the inner wall of the fixed box 501, the outer wall of the threaded block 504 is slidably connected to the inner wall of the through groove 401, and the bottom of the threaded block 504 extends to the outside of the through groove 401 and is connected to a third fixed plate 506, two third springs 505 are connected to the top of the third fixed plate 506, and the other end of the third spring 505 is connected to the bottom of the first fixed block 402.

[0031] The specific implementation method is as follows: the bidirectional threaded rod 503 is driven to rotate by rotating the output shaft of the motor 502. When the bidirectional threaded rod 503 rotates, the two sections of opposite threads provided on the outer wall of the bidirectional threaded rod 503 can respectively drive the two threaded blocks 504 to approach or move away from each other, thereby enabling the first fixed block 402 to move through the third fixed plate 506 and the third spring 505. The movement of the first fixed block 402 drives the second fixed block 404 to move, and the second fixed block 404 can drive the first extrusion block 408 and the first pulley 407 to move through the second spring 405 and the first fixed plate 406. At the same time, the second fixed block 404 can also drive the second extrusion block 409 and the second pulley 411 to move through the first spring 403 and the second fixed plate 410, so that the position of the second pulley 411 can be adjusted, so that the second pulley 411 can position iron blocks 1 of different widths, thereby improving the applicability of the auxiliary device.

[0032] Working principle: When in use, the angle grinder body 2 and the fixed box 501 are driven downward by the handle 3, the fixed box 501 drives the two threaded blocks 504 and the third fixed plate 506 to move downward through the internal bidirectional threaded rod 503, the third fixed plate 506 drives the first fixed block 402 and the two second fixed blocks 404 to move downward through the two third springs 505, the second fixed block 404 drives the second extrusion block 409 and the second pulley 411 to move downward through the first spring 403 and the second fixed plate 410, and at the same time the second fixed block 404 can also move downward through the second spring 405 and the first fixed The fixed plate 406 drives the first extrusion block 408 and the first pulley 407 to move downward, so that the first pulley 407 contacts the ground. Since the elastic force of each third spring 505 is greater than the elastic force of the first spring 403 plus the second spring 405, the first pulley 407 can be squeezed by the ground and drive the first extrusion block 408 to move upward. At the same time, the second spring 405 can be compressed by the first fixed plate 406. The upward movement of the first extrusion block 408 can squeeze one side of the second extrusion block 409. Due to the squeezing of the first extrusion block 408 and the second extrusion block 409, One side is inclined, so the second extrusion block 409 can drive the first spring 403 to stretch through the second fixed plate 410, and at the same time can drive the second pulley 411 to contact the side of the iron block 1, so that the iron block 1 can be positioned, so that the angle grinder body 2 can move along the iron block 1 without deviation. When it is necessary to grind iron blocks 1 of different widths, the motor 502 is started, and the output shaft of the motor 502 rotates to drive the bidirectional threaded rod 503 to rotate, so that the bidirectional threaded rod 503 can drive the two threaded blocks 504 to approach each other through the two opposite threads set on its outer wall. Or they are away from each other, and can drive the first fixed block 402 and the two second fixed blocks 404 to move through the third fixed plate 506 and the third spring 505. The second fixed block 404 can drive the first extrusion block 408 and the first pulley 407 to move through the second spring 405 and the first fixed plate 406. At the same time, the second fixed block 404 can also drive the second extrusion block 409 and the second pulley 411 to move through the first spring 403 and the second fixed plate 410, so that the position of the second pulley 411 can be adjusted, so that the second pulley 411 can position iron blocks 1 of different widths.
