DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-3A clamping device for a blade grinder comprises a base 1, which is fixedly mounted on the base of the grinder by welding, two support frames 2 are fixed on the top of the base 1, a rotating shaft 3 is rotatably mounted in the middle between the two support frames 2, and both ends of the rotating shaft 3 extend to the outside of the support frames 2, and angle control devices are rotatably mounted at both ends of the rotating shaft 3, and fan-shaped plates 4 are fixedly mounted on the sides of the two support frames 2 away from each other, and the angle control device comprises a U-shaped fixed frame 18, the two ends of the rotating shaft 3 are rotatably connected to the fixed frame 18, and thin rods 19 are fixedly connected to the bottom of the fixed frame 18 at equal distances, and the clamps between adjacent thin rods 19 The angle is 1 degree. Square grooves are equidistantly provided on the front of the sector plate 4. The width of the square grooves is equal to the outer diameter of the thin rod 19. The square grooves are tightly matched with the thin rod 19. A rectangular support plate 5 is fixedly connected to the middle of the rotating shaft 3. A fixed splint 6 is fixed to the lower part of the side of the support plate 5. A limiting plate 7 is fixed to the end of the side of the support plate 5 away from the fixed splint 6. A square straight rod 8 is movably connected to the middle of the limiting plate 7. A movable splint 9 is fixedly connected to the bottom of the square straight rod 8. A plastic pad is fixedly connected to the end of the fixed splint 6 and the movable splint 9 that are close to each other. A slider 10 is hinged to the end of the square straight rod 8 away from the movable splint 9. A support rod 11 is fixed on the top of the support plate 5, and the end of the support rod 11 away from the support plate 5 is rotatably connected to a long rod 12, and a slider 10 is movably sleeved on the end of the long rod 12 close to the limit plate 7, and a handle 13 is fixed to the end of the long rod 12 away from the slider 10. The support rod 11 is located between the handle 13 and the slider 10, and the distance between the support rod 11 and the slider 10 is much smaller than the distance between the support rod 11 and the handle 13. The long rod 12 is a rectangular structure, and barbed fixing teeth 14 are equidistantly provided at the bottom of the long rod 12. The middle part of the side of the support plate 5 away from the fixed splint 6 is hinged with a first connecting rod 15. The first connecting rod 15 One end of the rod 15 away from the hinge is rotatably connected to the second connecting rod 16 through a rotating shaft. A locking sleeve 17 is movably sleeved at the junction of the first connecting rod 15 and the second connecting rod 16. The diameter of the first connecting rod 15 is equal to the diameter of the second connecting rod 16. The locking sleeve 17 is tightly matched with the first connecting rod 15 and the second connecting rod 16. The locking sleeve 17 is a hollow cylindrical structure. A rubber pad is fixedly connected to the outer wall of the locking sleeve 17. The long rod 12, the first connecting rod 15, the second connecting rod 16, and the thin rod 19 are all made of stainless steel metal materials, and the long rod 12, the first connecting rod 15, the second connecting rod 16, and the thin rod 19 are all solid structures.

[0023] In the present invention, the tool is placed on the fixed clamping plate 6, the position is adjusted, the handle 13 is grasped and lifted upward, and the square straight rod 8 is driven downward by the long rod 12, so that the movable clamping plate 9 clamps the tool, and the force arm of the end of the long rod 12 close to the handle 13 is much longer than the force arm length of the other side, so the clamping force is relatively large, and the tool is not easy to fall off and slide. Then, the second connecting rod 16 is used to support the fixed teeth 14 at the bottom of the long rod, so that the long rod 12 will not rotate. Sometimes the tool needs a pointed tip, and at this time, it is only necessary to rotate the fixing frame 18 , let the thin rod 19 disengage from the square groove, rotate the support plate 5, because the angle between each thin rod 19 is 1 degree, you only need to count the number of thin rods 19, when the angle is adjusted, rotate the fixing frame 18 to put the thin rod 19 into the square groove, and when releasing the tool, you only need to move the locking sleeve 17 so that the intersection of the first connecting rod 15 and the second connecting rod 16 leaks out. At this time, the first connecting rod 15 and the second connecting rod 16 can rotate, and the fixing effect on the fixed tooth 14 is lost. The tool can be released by rotating the long rod 12.

[0024] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
