Plastic fasteners are fasteners made of plastic materials and are used to connect and fix various components. Lightweight: Compared with metal fasteners, plastic fasteners are lighter, which helps to reduce the weight of the overall product. Plastic materials have excellent corrosion resistance and are suitable for a variety of environments and conditions. Plastic fasteners usually have good insulation properties and are suitable for use in electrical and electronic fields.

[0020] The working principle of the above technical solution is as follows: when in use, the user places the fastener to be clamped on the top of the column plate 22, and manually rotates the rotating worm 3. When the rotating worm 3 rotates, it drives the transmission meshing turbine ring 8 to rotate, thereby prompting the support plate 7 to rotate. The arc groove 10 on the inner side of the support plate 7 rotates to produce an oblique squeezing effect on the slide column 11, and prompts the slide column 11 to apply a force to the slide frame 2 12 and the slider 1 15, so that the slide column 11 moves under the limit of the arc groove 10, and drives the slide frame 2 12 and the slider 1 15 to move, so that the slide frame The second 12 moves toward the outside of the column plate 22, causing the clamped workpiece 21 to be clamped on the outside of the fastener. At this time, the adjusting bolt 25 does not limit the slider 17 so that the clamping effect of the clamped workpiece 21 is transmitted to the slider 17 through the slide rod 18. The slider 17 slides inside the slide frame 12 and compresses the spring 19, so that the clamped workpiece 21 is elastically fitted to the outside of the fastener. After clamping, bolts are inserted into the turntable 5 and the positioning hole 6 to fix the transmission worm 4, and then the fiber turbine ring 8 and the support plate 7 rotate, stabilizing the clamping position and facilitating clamping.

[0021] In another embodiment, Figure 1-Figure 3 As shown, the support plate 2 is fixedly installed on the top of the base 1.

[0022] The support plate 2 provides rotation support for the rotating worm 3 and the transmission worm 4, thereby stabilizing the structure.

[0023] In another embodiment, Figure 1 and Figure 3 As shown, the positioning holes 6 are evenly distributed in a circle inside the turntable 5 , and bolts are inserted into the positioning holes 6 , and the bolts movably penetrate the positioning holes 6 and extend to penetrate the inside of the support plate 2 .

[0024] Inserting bolts into the support plate 2 through the positioning hole 6 can fix the position of the turntable 5, thereby keeping the transmission worm 4 from rotating, thereby stabilizing the positions of the turbine ring 8 and the support plate 7, and facilitating a stable clamping position.

[0025] In another embodiment, Figure 1-Figure 4 As shown, the slider 17 is movably installed inside the slide frame 12, the end of the spring 19 away from the slider 17 is fixedly installed inside the slide frame 12, the outer side of the adjusting bolt 25 is threadedly connected to the inner side of one end of the slide frame 12, and one end of the adjusting bolt 25 is movably contacted with one side of the slider 17.

[0026] Slider 2 17 provides sliding support force for slide bar 2 18, and stably transmits the elastic force of spring 2 19 to slide bar 2 18 and positioning plate 20 to cooperate with the clamping of special-shaped parts. When the adjusting bolt 25 rotates to the position in contact with slider 2 17, the movement of limit slider 2 17 at this time makes slider 2 17 and slide frame 2 12 move as a whole, which is convenient for transmitting the rigid clamping effect to the positioning plate 20 and the mounting plate 23, and is convenient for clamping different workpieces, thereby increasing adaptability.

[0027] In another embodiment, Figure 1-Figure 4 As shown, the arc grooves 10 are evenly distributed in a circle inside the support plate 7, and the slide frames 9 are evenly distributed in a circle on the top of the base 1.

[0028] By means of the provided mounting plate 23 and positioning plate 20, when clamping different fasteners, the mounting plate 23 can be removed and replaced with different clamping fixtures, which is convenient for replacement. At the same time, in conjunction with the multiple provided sliding frames 12 and 1 9, the column plate 22 is moved and clamped relative to each other, so as to be suitable for clamping operations of different plastic fasteners, facilitate the clamping operations of special-shaped parts, increase the clamping operations of more fasteners, and facilitate the increase of centripetal clamping to cope with different clamping parts.

[0029] In another embodiment, Figure 1 and Figure 3 As shown, the slider 15 is slidably installed inside the slide frame 9, the slide frame 9 is fixedly installed on the top of the base 1, the spring 16 is sleeved on the outside of the slide rod 14, and the end of the spring 16 away from the slider 15 is fixedly installed inside the slide frame 9.

[0030] The slider 15 and the slide rod 14 move within the slide frame 9 to facilitate the movement of the arc groove 10 and the slide column 11, and to stabilize the moving force. The spring 16 provides elastic force to stably push the arc groove 10 and the slide column 11, and to assist the slide column 11 to move inward and clamp, thereby increasing the smoothness of the structure operation.
