[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Specific examples are given below.

[0026] like Figure 1-3As shown, a diamond roller that is easy to position comprises a roller body 1; a hole 11 is opened in the middle of the roller body 1; two groups of slide grooves 12 are opened on the inner wall of the roller body 1; a first rotating shaft 13 is rotatably connected to the middle of the roller body 1; two groups of inner grooves 14 are opened in the middle of the first rotating shaft 13, and the two groups of inner grooves 14 are symmetrically arranged in the middle of the first rotating shaft 13; a slider 15 is threadedly connected to the middle of the first rotating shaft 13, and the slider 15 is slidably arranged on the inner wall of the slide groove 12; the middle of the slider 15 is gradually inclined; two groups of clamping plates 16 are connected to the torsion spring on the inner wall of the slide groove 12, and the middle part of the clamping plate 16 is in contact with the end of the roller body 1; when working, the staff needs to align the hole 11 at the end of the roller body 1 with the output end of the external grinder, and after the output end is clamped on the inner wall of the hole 11, by arranging two groups of first rotating shafts 13 in the middle of the roller body 1, the staff can The first rotating shaft 13 is rotated with a tool, and after the first rotating shaft 13 is rotated, under the action of the two sets of symmetrically arranged inner grooves 14, the slider 15 can be driven to move relatively synchronously on the inner wall of the slide groove 12. Because the middle part of the slider 15 is gradually inclined, when the highest point of the end of the slider 15 moves toward the middle of the roller body 1, the slider 15 can push the clamping plate 16 to the position of the hole 11, and at the same time, the end of the clamping plate 16 will contact the output end in the middle of the hole 11. After continuing to rotate the first rotating shaft 13, the position between the clamping plate 16 and the output end can be reinforced. This step cooperates with the clamping plate 16 set, and the output ends of different diameters can be clamped and fixed. At the same time, when the aperture of the hole 11 is larger than the aperture of the output end, the speed of the staff in installing the hole 11 on the grinder can be reduced, and the diameter of the middle part of the two is reduced to be similar, so that it is difficult to get the roller body 1 stuck at the output end of the grinder under the action of friction.

[0027] like Figure 1 , 2As shown in , 4 and 5, the outer wall of the roller body 1 is fixedly connected to the first fixing rod 2; the outer wall of the roller body 1 is fixedly connected to the second fixing rod 21; the middle of the first fixing rod 2 and the second fixing rod 21 is rotatably connected to the rotating drum 22; the end of the first rotating shaft 13 is rotatably connected to the belt 23, and the inner wall of the belt 23 is in contact with the bottom of the two groups of rotating drums 22; the ends of the first fixing rod 2 and the second fixing rod 21 are provided with a limiting plate 24; when working, by arranging the first fixing rod 2 and the second fixing rod 21 on the outer wall of the roller body 1, when the staff rotates a group of first rotating shafts 13, the first rotating shafts 13 will synchronously drive the belt 23 to rotate, At the same time, it drives another group of first rotating shafts 13 to rotate synchronously, and under the action of the two groups of rotating drums 22, the working position of the belt 23 can be shifted downward, and this is repeated, and the vertical limiting plate 24 can limit the position of the belt 23 during operation. This step, combined with the set belt 23, can reduce the problem that the staff needs to rotate the two groups of first rotating shafts 13 in turn, and reduce the difference in the number of rotations of the two groups of first rotating shafts 13, which causes the two groups of clamps 16 to fix the output end insufficiently and shake. At the same time, combined with the unfolded limiting plate 24, it can reduce the problem of the belt 23 being separated from the drum 22 when working.

[0028] like Figure 5 As shown, a spring 3 is fixedly connected to the inner wall of the first fixing rod 2; the end of the spring 3 is rotatably connected to the connecting rod 31; the end of the connecting rod 31 is fixedly set with the limiting plate 24; a slot 32 is opened in the middle of the second fixing rod 21; a block 33 is fixedly connected to the middle of the limiting plate 24, and the block 33 and the slot 32 are polygonal settings; during work, by arranging a spring 3 on the inner wall of the first fixing rod 2, when the belt 23 needs to be replaced during work, the limiting plate 24 can be pulled upward by hand, and the length of the spring 3 will be stretched after the force is applied until the block 33 is separated from the slot 32. At this time, the staff can rotate the limiting plate 24 so that the limiting plate 24 is in a horizontal state as a whole, and then the belt 23 can be disassembled and taken out. This step is combined with the setting of a rotatable limiting plate 24, which can improve the flexibility of replacing the belt 23, reduce the trouble of taking out the belt 23, and at the same time improve the speed of cleaning the first rotating shaft 13 and the inner groove of the rotating drum 22 by the staff.

[0029] like Figure 4As shown, the torsion spring on the outer wall of the roller body 1 is connected to the second rotating shaft 4; the middle part of the second rotating shaft 4 is fixedly connected to a scraper 41; the end of the scraper 41 is arranged in contact with the belt 23; during operation, by arranging the second rotating shaft 4 on the outer wall of the roller body 1, when the belt 23 is moving, the scraper 41 in direct contact with the belt 23 will scrape off the impurities accumulated on the surface of the belt 23, and at the same time utilize the shaking force after the second rotating shaft 4 is reset to discharge the impurities to the outside. This step cooperates with the scraper 41 to improve the cleanliness of the middle part of the belt 23, reduce the problem that the roller body 1 will generate more impurities and adhere to the middle part of the belt 23 after use, and the belt 23 will be damaged by wear or corrosion after long-term accumulation, thereby improving the service life of the belt 23.

[0030] like Figure 3 As shown, a groove 5 is provided at the end of the slider 15; a rotating wheel 51 is rotatably connected to the inner wall of the groove 5, and the middle part of the rotating wheel 51 is arranged in contact with the splint 16; during operation, by arranging the rotating wheel 51 at the end of the slider 15, when the slider 15 is in use, the rotating wheel 51 at its end will rotate on the inner wall of the groove 5 under the action of friction, and the middle part of the rotating wheel 51 can gradually contact with the splint 16. This step cooperates with the arrangement of the rotating wheel 51 to reduce the problem that the end of the splint 16 directly contacts the middle part of the splint 16, resulting in greater wear on the splint 16 or the middle part of the slider 15, and reduces the problem of loose fixing of the splint 16 when the slider 15 is used later.

[0031] like Figure 3 As shown, the end of the clamping plate 16 is fixedly connected with a friction plate 6; the middle part of the friction plate 6 is recessed; during operation, by arranging the friction plate 6 at the end of the clamping plate 16, after the clamping plate 16 is close to the output end of the grinder, the friction plate 6 will directly contact the surface of the output end. This step cooperates with the friction plate 6 to improve the stability of the clamping plate 16 in fixing the output shaft of the grinder, and reduce the problem of large wear or looseness of the output end when it rotates rapidly.

[0032] like Figure 5 As shown, the middle part of the limit plate 24 is fixedly connected with a friction pattern 7; during operation, by setting the friction pattern 7 in the middle part of the limit plate 24, after the staff pulls the limit plate 24, their hands can first contact the middle part of the friction pattern 7. This step, combined with the set friction pattern 7, can reduce the problem of excessive sweat on the hands of the staff, which causes the hand to slip after pulling the limit plate 24.

[0033] Working principle: by aligning the hole 11 at the end of the roller body 1 with the output end of the external grinder, and clamping the output end on the inner wall of the hole 11, two sets of first rotating shafts 13 are arranged in the middle of the roller body 1, so that the staff can use tools to rotate the first rotating shafts 13 in turn, and after the first rotating shaft 13 rotates, under the action of the two sets of symmetrically arranged inner grooves 14, the slider 15 can be driven to move relatively synchronously on the inner wall of the slide groove 12. Because the middle part of the slider 15 is gradually inclined, when the highest point of the end of the slider 15 moves toward the middle of the roller body 1, the slider 15 can move the clamping plate 16 to the position of the hole 11. The first rotating shaft 13 is rotated continuously, and the position between the clamping plate 16 and the output end can be reinforced. The first fixing rod 2 and the second fixing rod 21 are arranged on the outer wall of the roller body 1, so that when the staff rotates one group of first rotating shafts 13, the first rotating shafts 13 will synchronously drive the belt 23 to rotate, and at the same time drive the other group of first rotating shafts 13 to rotate synchronously, and under the action of the two groups of rotating drums 22, the working position of the belt 23 can be shifted downward, and this is repeated, and the vertical limit plate 24 can make the belt 23 at work 3 is used to limit the position. By arranging a spring 3 on the inner wall of the first fixing rod 2, when the belt 23 needs to be replaced during work, the limiting plate 24 can be pulled upward by hand, and the length of the spring 3 will be stretched after being stressed until the block 33 and the card slot 32 are separated. At this time, the staff can rotate the limiting plate 24 so that the limiting plate 24 is in a horizontal state as a whole, and then the belt 23 can be disassembled and taken out. By arranging a second rotating shaft 4 on the outer wall of the roller body 1, when the belt 23 is moving, the scraper 41 in direct contact with the belt 23 will scrape off the impurities accumulated on the surface of the belt 23, and at the same time The shaking force after the second rotating shaft 4 is reset is utilized to discharge impurities to the outside. A rotating wheel 51 is provided at the end of the slider 15, so that when the slider 15 is in use, the rotating wheel 51 at its end will rotate on the inner wall of the groove 5 under the action of friction, and the middle part of the rotating wheel 51 can gradually contact with the clamping plate 16. A friction plate 6 is provided at the end of the clamping plate 16, so that after the clamping plate 16 is close to the output end of the grinder, the friction plate 6 will directly contact with the output end surface. A friction pattern 7 is provided in the middle of the limit plate 24, so that after the staff pulls the limit plate 24, his hand can contact the middle part of the friction pattern 7 first.
