[0024] The upper end of the abrasive belt guide rail 5 is provided with a notch 9 matched with the driving wheel 19, the driving wheel 19 is installed in the notch 9, and a detachable driven wheel module 10 is installed at the lower end of the abrasive belt guide rail 5, the driven wheel 7 is installed on the driven wheel module 10, the shape of the driven wheel module 10 is matched with the structure of deep narrow slot, that is, the two side walls and bottom of the driven wheel module 10 are respectively parallel to the two sides and bottom of deep narrow slot, if the deep narrow slot is trapezoidal structure with length gradually reducing from top to bottom, then the driven wheel module 10 is also trapezoidal structure, if the deep narrow slot is inclined structure, then the bottom surface of the driven wheel module 10 is also inclined structure, so as to ensure that each position of deep narrow slot can be ground to the greatest extent during grinding.

[0025] The driving wheel 19 is composed of rear wheel 16 and front wheel 17, the rear wheel 16 is provided with a plurality of plug-in parts 18 arranged in a circumferential direction close to one side of the front wheel 17, the front wheel 17 is provided with plug-in grooves corresponding to the plug-in parts 18, the plug-in parts 18 are plugged into the plug-in grooves and fixed by guide column screws, to form the driving wheel 19, the plug-in parts 18 are provided with round holes 20, the plug-in grooves are provided with internal thread holes 23 corresponding to the round holes 20, the front end of the guide column screw is provided with a guide column 25, and the rear end is provided with an external thread part 26, the guide column 25 is plugged into the round hole 20, and the external thread part 26 is screwed into the internal thread hole 23, the guide column 25 rotates in the round hole 20 (only rotation occurs, and the guide column 25 will not exit from the round hole 20, which is the existing screw structure), the front wheel 17 is connected to the rear wheel 16 through the internal thread hole 23 and the external thread part 26, and moves towards or away from the rear wheel 16, so as to adjust the width of the driving wheel 19, and the detachable driven wheel module 10 can be replaced, so as to replace the abrasive belt 8 with different widths, and grind deep narrow slots with different widths.

[0026] The body 2 is equipped with a vertical height adjustment guide rail 11, and the sliding plate 4 is equipped with a corresponding slider 12. The slider 12 is slidably mounted on the height adjustment guide rail 11. The sliding plate 4 has the effect of moving up and down. A rack is installed on the side wall of the sliding plate 4. The body 2 is equipped with a gear that is rotated by a control handle 22. The gear is connected to the rack. By turning the control handle 22, the gear is rotated, thereby causing the sliding plate 4 to move up and down through the rack.

[0027] A limiting platform 13 is installed at the lower end of the machine body 2. A compression spring 14 is installed between the limiting platform 13 and the slider 12. The compression spring 14 is always in a compressed state. During the grinding process, the worker needs to hold the control handle 22 at all times to keep the grinding belt 8 in contact with the deep and narrow groove. This also allows the worker to pull up the grinding belt 8 after grinding for a certain period of time to observe the grinding effect. If the grinding is insufficient, it can be ground again in time. If a good grinding effect is achieved, the next product can be replaced for grinding, which is more flexible. When the control handle 22 is released, the compression spring 14 will reset and return to the starting point.

[0028] This product can also be fixed in position using pneumatic control. That is, during grinding, the worker uses the control handle 22 to bring the abrasive belt 8 into contact with the deep, narrow groove, and then opens the pneumatic control valve (e.g., ...). Figure 1 As shown in Figure A (which is a simplified illustration and belongs to the prior art, and will not be described in detail), the position of the sliding plate 4 is fixed by air pressure. At this time, the worker can release the control handle 22 and wait for the grinding to be completed. Then, the worker closes the air pressure control valve, and the compression spring 14 will reset and return to the starting point on its own, or the air pressure control valve will automatically release. This requires adjustment of the opening time of the air pressure control valve, and sufficient grinding time is required to ensure the grinding effect.

[0029] The adjustable height depth limiting screw 15 is installed below the slider 12 on the limiting platform 13, and the position of the depth limiting screw 15 needs to be adjusted when grinding different products; when the grinding belt 8 is in contact with the bottom of the deep and narrow groove (actually in contact with the bottom of the deep and narrow groove that has been ground), the bottom surface of the slider 12 is in abutment with the depth limiting screw 15, and the depth limiting screw 15 prevents the sliding plate 4 from moving downward too much; without the depth limiting screw 15, the worker needs to maintain high concentration at all times to avoid the problem of the control handle 22 being moved too hard, which causes the grinding belt 8 to be pressed too hard, the friction between the grinding belt 8 and the deep and narrow groove is greater, and problems such as excessive grinding, rapid consumption of the surface grit of the grinding belt 8, reduction of the service life and the like occur; even when the pressure is large enough, the grinding belt 8 is pressed tightly between the driven wheel module 10 and the deep and narrow groove and cannot rotate, the driving wheel 19 controlled by the motor 6 is always rotating, and the grinding belt 8 is directly pulled off.

[0030] The base 1 is provided with a front and rear movable lower workbench 24, and the lower workbench 24 is provided with a left and right movable upper workbench 21, and the clamp 3 is installed on the upper workbench 21. Figure 1 As shown in B of FIG. 1, the knob is manually screwed, the screw rod is rotated by rotating the knob, the lower workbench 24 and the upper workbench 21 are moved, and the position of the clamp 3 is adjusted.
