[0015] 2. The anti-scattering device of the wire wheel is provided with a wire wheel component group. The current wire wheel disassembly and installation efficiency is low. Under the condition of large workload, the wire wheel needs to be replaced with a new wire wheel after it is worn. In the prior art, the efficiency of disassembling and installing the wire wheel from the angle grinder is low, thereby reducing the use efficiency. In the corresponding designed wire wheel component group, when the wire bundle is completely worn out and cannot be used, the pinching handles on both sides are pinched to move closer to each other, allowing the spring part to accumulate force and contract. At this time, the card block will be removed from the card slot of the outer cylinder part, and then the wire bundle, outer cylinder part, and dynamic extrusion part can be The structure composed of the plate and the adjusting screw is taken out from the inner cylinder part, and a new structure is replaced after taking it out. The pinching handle is pinched to make the card block be located in the slide groove of the inner cylinder part, and then the replaced structure is placed on the inner cylinder part, and then the pinching of the pinching handle is released. At this time, the card block will be pushed out into the groove of the outer cylinder part by the accumulated force of the spring part. At this time, the inner cylinder part and the outer cylinder part are connected. Compared with the prior art design that requires rotating the locking cover plate to remove or connect it to the drive shaft every time the wire wheel is replaced, this overall design is faster when replacing a new wire wheel, thereby achieving the purpose of improving work efficiency.

[0024] The inner cylinder member 21 is sleeved on the driving shaft 12 through the through hole. The inner cylinder member 21 is clamped between the locking cover plate 14 and the gasket 13. The inner cylinder member 21 and the outer cylinder member 22 are in contact through the groove.

[0025] A plurality of steel wire bundles 23 are provided, and one end of each of the plurality of steel wire bundles 23 is connected to the outer cylinder 22 . Three adjusting screws 24 are provided, and the three adjusting screws 24 are distributed in an annular shape on the dynamic extrusion plate 25 .

[0026] The adjusting screw 24 contacts the adjusting screw 24 through the hole, and the adjusting screw 24 is connected to the outer cylinder 22 through the threaded hole. The head of the adjusting screw 24 is used to contact the movable extrusion plate 25.

[0027] The movable extrusion plate 25 contacts the steel wire bundle 23 , and the fixed extrusion plate 26 is fixedly connected to the outer cylinder 22 through the through hole, and the fixed extrusion plate 26 contacts the steel wire bundle 23 .

[0028] Two groups of the pinching handle 27 , the clamping block 28 and the spring member 29 are provided, and the two groups of the pinching handle 27 , the clamping block 28 and the spring member 29 are symmetrically distributed on both sides of the inner cylinder member 21 .

[0029] The outer cylinder 22 is in contact with the clamping block 28 via the clamping groove, the spring 29 is connected between the clamping block 28 and the inner cylinder 21 , and the clamping block 28 is in sliding contact with the inner cylinder 21 via the sliding groove.

[0030] Working principle: After long-term use, the current wire wheel will become loose. The existing wire wheel lacks an anti-loosening structure, which makes the loose wire wheel unable to be used effectively, reducing the service life of the wire wheel. In the corresponding designed wire wheel component group 02, when the wire bundle 23 becomes loose after being used for a period of time, the adjusting screw 24 is adjusted and rotated to move the adjusting screw 24 toward the direction of the outer cylinder 22. The adjusting screw 24 moves in the threaded hole of the outer cylinder 22. The screw 24 moves, allowing the head of the adjusting screw 24 to contact the dynamic extrusion plate 25, allowing the dynamic extrusion plate 25 to move toward the fixed extrusion plate 26. By continuously shortening the distance between the dynamic extrusion plate 25 and the fixed extrusion plate 26, the purpose of clamping the middle position of the wire bundle 23 is achieved. The design of this wire wheel component group 02 prevents the wire bundle 23 from loosening when the dynamic extrusion plate 25 and the fixed extrusion plate 26 are used to clamp the middle position of the wire bundle 23 according to the looseness of the wire bundle 23, thereby extending the service life of the wire wheel. The current wire wheel disassembly and installation efficiency is low. Under the condition of large workload, the wire wheel needs to be replaced with a new wire wheel after it is worn. In the existing technology, the efficiency of disassembling and installing the wire wheel from the angle grinder is low, thereby reducing the use efficiency. In the corresponding designed wire wheel component group 02, when the wire bundle 23 is completely worn to the point of being unusable, the pinching handles 27 on both sides are pinched close to each other to allow the spring part 29 to accumulate force and contract. At this time, the block 28 will be removed from the slot of the outer cylinder part 22, and then the structure consisting of the wire bundle 23, the outer cylinder part 22, the movable extrusion plate 25 and the adjusting screw 24 can be removed from the inner cylinder part. 21, replace the new structure after taking it out, pinch the handle 27 to make the block 28 located in the slide groove of the inner cylinder 21, then put the replaced structure into the inner cylinder 21, and then release the pinching of the handle 27. At this time, the block 28 will be pushed out into the groove of the outer cylinder 22 by the spring part 29. At this time, the inner cylinder 21 and the outer cylinder 22 are connected. Compared with the prior art design that requires rotating the locking cover 14 to remove or connect it to the drive shaft 12 every time the wire wheel is replaced, this overall design is faster when replacing a new wire wheel, thereby achieving the purpose of improving work efficiency.
