[0028] Principle and advantage: by setting the limiting mechanism 5, the device can be twisted and adjusted during actual use. When the sliding ring 532 is turned, it will squeeze the torsional spring 531 and make it tighten. During the tightening process of the torsional spring 531, the limiting frame 533 and the limiting arc tube 52 can be overlapped with each other. In this state, the sliding block 3 can be smoothly inserted into the inside of the sliding groove 2. Because the sliding groove 2 and the sliding block 3 can be inserted into each other, they can be installed on the outside of the mounting disc 1. Then, when the torsional spring 531 resets, it will drive the sliding ring 532 to slide outward. With the sliding ring 532 sliding outward, the limiting frame 533 will move outward synchronously. The limiting frame 533 and the limiting arc tube 52 are arranged in a ring shape. At this time, the limiting frame 533 can be inserted into the inside of the limiting arc tube 52. Through the mutual insertion and limiting action of the limiting frame 533 and the limiting arc tube 52, the sliding block 3 can be removed from the inside of the sliding groove 2. Therefore, during the overall use of the device, it is convenient to realize quick disassembly and greatly improves the use efficiency. The mounting disc 1 is fixedly installed with a fixed shaft 62 at the top middle and a sleeve frame 63 at the bottom. The sleeve frame 63 can be inserted with an insertion block 64, and the bottom of the insertion block 64 is connected with the top of the fixed shaft 62. The insertion block 64 and the sleeve frame 63 are provided with limiting grooves 65 at the middle of both sides. The limiting grooves 65 are limited by limiting assemblies 66. The cross rails 661 of the limiting assemblies 66 are fixed at the middle of one side of the sleeve frame 63. The inside is rotatably connected with lead screws 662. The lead screws 662 have adjusting handles 663 at one end and opposite screw threads at both ends. The outer surfaces of the lead screws 662 are threadedly connected with sliding blocks 3. The sliding blocks 3 slide at both ends inside the cross rails 661. One side of the sliding blocks 3 is connected with base plates 665. The inside of the base plates 665 is fixedly provided with limiting blocks 666. The limiting blocks 666 can penetrate the limiting grooves 65 of the sleeve frame 63 and be inserted into the limiting grooves 65 of the insertion block 64. The mounting disc 1 is provided with mounting holes 667 at the bottom at equal intervals and is a countersunk hole, which is convenient for installation. This design makes the device easy to install on the equipment through the cooperation of the mounting holes 667 and bolts during installation. After the insertion block 64 is inserted into the sleeve frame 63, the lead screw 662 is rotated by twisting the adjusting handle 663, driving the sliding block 3 to slide, and making the limiting block 666 inserted into the limiting groove 65 to be fixed. The connection is stable. When disassembly is needed, the limiting block 666 can be separated from the limiting groove 65 by the same operation, and the insertion block 64 can be pulled out. It is convenient for maintenance and replacement of parts. The countersunk hole design makes the installation more beautiful and not easy to loosen.

[0029] By setting the mounting mechanism 6, so that the device during use, can be installed by bolt cooperation mounting hole 667 installed in the equipment, during use, after installation, can be inserted into the block 64 into the frame 63 inside, when the slider 664 inserted into the frame 63 inside, can be twisted by adjusting the handle 663 driven screw rod 662 rotation, it is worth noting that the two ends of the screw rod 662 thread direction is opposite, with the rotation of the screw rod 662, can assist in driving two sliders 664 reciprocating sliding displacement, when the slider 664 sliding displacement, will drive the limiting block 666 on the base plate 665 inserted into the limiting slot 65 inside, at this time, the limiting block 666 will penetrate the limiting slot 65 inserted into the limiting slot 65 inside the slider 664, through the limiting block 666 and the slider 664 limiting slot 65 of the mutual clamping effect, can be installed in the equipment at the bottom of the fixed disc 61, and if you need to disassemble, just need to twist the adjusting handle 663 driven screw rod 662 drive two sliders 664 outward sliding, when the slider 664 outward, can make the limiting block 666 from the limiting slot 65 inside, at this time, can be extracted from the block 64 into the frame 63 inside, in summary, the device during the whole use, whether it is each diamond brush body 4 or the whole device is convenient to disassemble, further greatly improves the convenience of the device used.
