Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0024] Reference Figure 1 and Figure 3 In this embodiment of the utility model, a rotary adjustment tool includes: a blade assembly 1, an adjustment seat assembly 2 fixedly disposed on both sides of the blade assembly 1, an adjustment cover assembly 3 screwed to the outside of the adjustment seat assembly 2, a locking assembly 4 installed inside the adjustment cover assembly 3, the adjustment seat assembly 2 including an adjustment seat component 1 20, a bolt fastener 21 passing through one end of the adjustment seat component 1 20, an adjustment seat component 22 disposed on the outside of one end of the bolt fastener 21, and two sets of adjustment cover assembly 3 and locking assembly 4 are provided. The two sets of adjustment cover assembly 3 and locking assembly 4 are respectively located on both sides of the adjustment seat assembly 2 and screwed together. The bolt fastener 21 is adapted to pass through the blade mounting through hole 12, the adjustment seat mounting through hole 1 202 and the adjustment seat mounting through hole 207.

[0025] Reference Figure 2 The blade assembly 1 includes a blade body 10, and a blade fixing ring 11 is fixedly installed inside the blade body 10. The blade fixing ring 11 has a through-hole 12 for blade installation, and there are three sets of blade installation through-holes 12.

[0026] Reference Figure 4 The adjusting cover assembly 3 includes an adjusting cover frame 30. An arc-shaped adjusting insert plate 31 is fixedly installed at one end inside the adjusting cover frame 30. A countersunk hole 32 for pressing plate is opened at the other end inside the adjusting cover frame 30. A pressing screw hole 33 is opened through one end inside the countersunk hole 32. An internal thread structure is opened on the side inside the adjusting cover frame 30.

[0027] Reference Figure 5 The locking assembly 4 includes a metal locking washer 40 and a pressing locking bolt 41. One end of the pressing locking bolt 41 is fixedly provided with a locking pressing plate 42. The locking pressing plate 42 is movably attached to the metal locking washer 40. The pressing locking bolt 41 is adapted to be screwed into the inside of the pressing screw hole 33.

[0028] By adopting the above solution, by rotating multiple sets of pressing and locking bolts 41, the locking and pressing plate 42 at one end of them presses against two sets of metal locking washers 40, thus pressing them tightly against both sides of the adjusting seat assembly 2, further tightening and locking can be achieved, making it more convenient to use.

[0029] Reference Figure 6 The adjusting seat component 20 includes an annular adjusting seat 200. One end of the annular adjusting seat 200 has a circular countersunk hole 201. The circular countersunk hole 201 has a through hole 202 for adjusting seat installation. One end of the annular adjusting seat 200 has an arc-shaped elastic locking block 203 fixedly installed. The inner surface of the arc-shaped elastic locking block 203 has locking anti-slip texture 204. There are three sets of the circular countersunk hole 201, the adjusting seat installation through hole 202, and the arc-shaped elastic locking block 203.

[0030] Reference Figure 7 The adjusting seat component 22 includes an annular adjusting seat 205. One end of the annular adjusting seat 205 has a hexagonal countersunk hole 206. The hexagonal countersunk hole 206 has an adjusting seat mounting through hole 207. An arc-shaped elastic locking block 208 is fixedly installed on one end of the inner side of the annular adjusting seat 205. The inner surface of the arc-shaped elastic locking block 208 is provided with locking anti-slip texture 209. There are three sets of hexagonal countersunk holes 206, adjusting seat mounting through holes 207, and arc-shaped elastic locking blocks 208.

[0031] Using the above solution: by rotating the adjustment cover assembly 3, it is screwed onto the outside of the adjustment seat component 1 20 and the adjustment seat component 22. As the adjustment cover assembly 3 is screwed in, the arc-shaped adjustment insert 31 will gradually be squeezed into the smaller gap on the outside of the arc-shaped elastic locking block 1 203 and the arc-shaped elastic locking block 208. The arc-shaped elastic locking block 1 203 and the arc-shaped elastic locking block 208 are squeezed and deformed inward, so that the locking anti-slip texture 1 204 and the locking anti-slip texture 209 fit against the rotating shaft. In this way, the locking of the rotating shaft of tools with different diameters can be achieved.

[0032] The working principle of this utility model is as follows: First, assemble the adjusting seat component 1 20 and adjusting seat component 22 on both sides of the blade assembly 1, aligning the adjusting seat mounting through holes 1 202, 207, and 12. Then, insert the bolt fixing component 21 through the circular countersunk hole 201, embedding the hexagonal nut of the bolt into the hexagonal countersunk hole 206. This secures the adjusting seat component 1 20 and adjusting seat component 22 to the blade assembly 1. Next, insert the metal locking washers 40 from the two sets of locking components 4 into the outer side of the arc-shaped adjusting plates 31 in the two sets of adjusting cover components 3. Then, align the arc-shaped adjusting plates 31 in the two sets of adjusting cover components 3 with the arc-shaped elastic locking block 203 and the arc-shaped elastic locking... After aligning the larger gap on the outer side of block 208, rotate the adjusting cover assembly 3 to screw it onto the outer side of adjusting seat component 1 20 and adjusting seat component 2 22. As the adjusting cover assembly 3 is screwed in, the arc-shaped adjusting insert 31 will gradually squeeze into the smaller gap on the outer side of the arc-shaped elastic locking block 1 203 and arc-shaped elastic locking block 208, squeezing the arc-shaped elastic locking block 1 203 and arc-shaped elastic locking block 208 inward to make the locking anti-slip texture 1 204 and locking anti-slip texture 209 fit against the rotating shaft. In this way, the rotating shafts of tools with different diameters can be locked. Then, by rotating the multiple sets of pressing locking bolts 41, the locking pressing plate 42 at one end of it presses against the two sets of metal locking washers 40, pressing them tightly against both sides of the adjusting seat assembly 2 to achieve further tightening and locking, making it more convenient to use.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
