[0024] Embodiment 2
[0025] See also Figure 1-Figure 3 On the basis of the first embodiment, the fixing device 9 includes an elastic rope 11, a clamping head 12 and a plurality of toothed blocks 14. The bottom of the elastic rope 11 is fixedly connected to the bottom wall of the cylindrical groove 8, and the top of the elastic rope 11 is fixedly connected to the bottom of the clamping head 12. The elastic rope 11 is elastic and can be retracted. The toothed block 14 is fixedly installed on one side of the clamping head 12. The toothed block 14 can prevent the clamping head 12 from falling off easily after being clamped with the clamping device 5.
[0026] The clamping device 5 includes a cloth belt 15 and a buckle head 19. The cloth belt 15 is placed in the concave strip 7. One end of the cloth belt 15 is fixedly connected to a side wall of the concave strip 7, and the other end of the cloth belt 15 is fixedly connected to the buckle head 19. The cloth belt 15 is arranged so that it can be flexibly separated from the concave strip 7, and the turntable is tightened and locked as needed. A clamping hole 20 is provided on the buckle head 19. The clamping hole 20 is arranged to facilitate clamping. A telescopic groove 21 is provided on one side wall of the clamping hole 20. A clamping block 17 is slidably connected in the telescopic groove 21. The clamping block 17 can be telescoped back and forth in the telescopic groove 21. A first spring 16 is arranged in the telescopic groove 21. It is precisely the first spring that Only with the existence of the first spring 16 can the block 17 in the telescopic slot 21 be telescoped back and forth, one end of the first spring 16 is fixedly connected to the block 17, and the other end of the first spring 16 is fixedly connected to the side wall of the telescopic slot 21, and the first spring is arranged in the telescopic slot 21. With the existence of the first spring 16, when the clamping head 12 is inserted into the clamping hole 20, the first spring 16 will make the block 17 firmly clamp the clamping head 12, and the two will not be easily separated. A first inclined surface 13 is arranged on the toothed block 14, and a second inclined surface 18 is arranged on one side of the block 17. The first inclined surface 13 and the second inclined surface 18 are arranged to prevent jamming during the clamping process, making the operation smoother.
[0027] When in use, first stretch the elastic rope 11 so that the clamping head 12 can be inserted into the clamping hole 20. When inserted into the clamping hole 20, the first spring 16 will shrink slightly. After the first toothed block 14 passes through the clamping hole 20, the first spring 16 will extend and drive the clamping block 17 to extend, so that the clamping block 17 firmly clamps the clamping head 12. At this time, it can be judged whether it is necessary to continue to insert the clamping head 12 to make it clamped tighter.
[0028] Embodiment 3
[0029] See also Figure 4-Figure 5 On the basis of the second embodiment, the buckle assembly 6 includes a slider 22 and a telescopic column 27. The slider 22 is slidably connected to the slide groove 10. The bottom of the telescopic column 27 is also slidably connected to the slide groove 10. The telescopic column 27 passes through the slider 22 and is fixedly connected thereto. In this way, the telescopic column 27 and the slider are integrated and can move together. The lower surface of the slider 22 is fixedly connected with a second spring 26. The second spring 26 is slidably connected to the telescopic column 27. One end of the second spring 26 is fixedly connected to the lower surface of the slide groove 10. The lower surface of the slide groove 10 also has a columnar slide groove. This columnar slide groove is slidably connected to the telescopic column 27. The side of the slider 22 is fixedly connected with a dial Block 23, the shift block 23 passes through the side wall of the slide groove 10 and is slidably connected thereto. By shifting the shift block 23, the slider 22 can be shifted to indirectly drive the telescopic column 27 to extend and retract. The top of the telescopic column 27 passes through the top arm of the slide groove 10 and is slidably connected thereto. A plurality of slots 28 are provided on the lower surface of the rotating disk 3. The slots 28 are adapted to the top of the telescopic column 27. The top of the telescopic column 27 extends into the slots 28 under the action of the second spring 26 to lock the rotating disk 3. A cone 25 is fixedly installed on the top of the telescopic column 27. The arrangement of the cone 25 is to make it easier for the telescopic column 27 to extend into the slots 28 to prevent it from rotating during use.
[0030] In actual use, firstly, the center of the turntable to be fixed is sleeved on the central shaft 4 and the turntable is placed on the upper surface of the rotating disk 3, and then the appropriate clamping device 5 and fixing device 9 are selected according to the shape and appearance of the turntable. After selection, the two are correspondingly clamped. In the clamping process, the elastic rope 11 is stretched so that the clamping head 12 can extend into the clamping hole 20. When the clamping hole 20 is extended, the first spring 16 will shrink slightly. When the first toothed block 14 passes through the clamping hole 20, the first spring 16 will extend and drive the clamping block 17 to extend, so that the clamping block 17 firmly clamps the clamping head 12. When the rotating disk 3 is rotated, the toggle block 23 can be pushed downward to move the slider 22, thereby indirectly driving the telescopic column 27 to extend and retract. When the telescopic column 27 leaves the card slot 28, the rotating disk 3 can be rotated. When it is rotated to a suitable position, the toggle block can be released. In this way, a variety of turntables with holes in the center can be firmly fixed no matter how much the appearance changes. The firmly fixed turntable can be rotated and locked by the buckle assembly 6, which effectively increases the flexibility of this fixing tool.
