The lead screw 120 can be provided in several groups, and each group of lead screw 120 is provided with an annular groove 130 at the connection. The head assembly 200 includes an umbrella-shaped head 210, a cross groove 220 and a flat notch 230 for adapting to different installation tools. The anti-slip assembly 300 includes a lower washer 310, an upper washer 320 located above the lower washer 310, lower teeth 330 formed on the surface of the lower washer 310, lower teeth 330 formed at the bottom of the upper washer 320, and anti-slip texture 350 for increasing the contact area. The upper teeth 340 and the lower teeth 330 mesh with each other.

[0022] like Figure 1-4 As shown, the anti-slip assembly 300 includes a lower washer 310, an upper washer 320, lower teeth 330, upper teeth 340, and anti-slip texture 350. The anti-slip texture 350 on the bottom of the lower washer 310 and the top of the upper washer 320 respectively contacts the mounting hole surface of the vehicle dashboard and the bottom of the umbrella-shaped head 210, thereby increasing the contact area and friction. The upper teeth 340 and the lower teeth 330 mesh with each other, which can effectively prevent relative sliding between the upper washer 320 and the lower washer 310. When the vehicle is bumpy, the anti-slip assembly 300 can fix the screw to the dashboard more tightly, reducing the possibility of loosening. Through the coordinated cooperation of the anti-slip assembly 300, the head assembly 200, and the screw assembly 100, the problem of screw loosening and unstable fixing caused by vehicle bumps can be effectively solved, improving the performance of the bamboo screw.

[0023] Example 2

[0024] Reference Figure 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0025] In this embodiment, anti-slip textures 350 are provided on the top of the upper pad 320 and the bottom of the lower pad 310. The anti-slip textures 350 at the bottom of the lower pad 310 are in contact with the mounting hole surface of the vehicle dashboard, and the anti-slip textures 350 at the top of the upper pad 320 are in contact with the bottom of the umbrella-shaped head 210.

[0026] A cross groove 220 is formed on the top of the umbrella-shaped head 210, and flat notches 230 are provided on both sides of the umbrella-shaped head 210. The flat notches 230 are used to engage the wrench.

[0027] One end of the smooth rod 110 is fixedly connected to the umbrella-shaped head 210, and the other end of the smooth rod 110 is fixedly connected to the annular groove rod 130. The annular groove rod 130 is fixedly connected to the lead screw 120. The annular groove rod 130 is used for screw cutting and segmentation.

[0028] Both the lower shim 310 and the upper shim 320 are fitted onto the surface of the smooth rod 110 and are movably connected to the smooth rod 110.

[0029] like Figure 1-4 As shown, the cross groove 220 and flat notch 230 in the head assembly 200 can be adapted to different installation tools. The cross groove 220 is convenient for installation with a screwdriver, while the flat notch 230 can be used to engage a wrench. With the right tool, the screw can be tightened with sufficient force, allowing the screw head to fit better with the dashboard. In the screw assembly 100, the annular groove 130 is located at the connection between the guide rod 110 and the lead screw 120, and each lead screw 120 connection is also provided with an annular groove 130. The annular groove 130 can play a certain buffering role. When the vibration generated by vehicle bumps is transmitted to the screw, the annular groove 130 can absorb some energy, reducing the impact of vibration on the connection between the screw and the dashboard, thereby improving the stability of the screw fixation. The length of the screw can also be adjusted by cutting the annular groove 130.

[0030] In use, one end of the smooth rod 110 of the screw assembly 100 is fixedly connected to the umbrella-shaped head 210 of the head assembly 200, and the other end is fixed to the annular groove rod 130. The annular groove rod 130 is then fixed to the lead screw 120. The lower washer 310 and upper washer 320 of the anti-slip assembly 300 are fitted onto the surface of the smooth rod 110 and are movably connected. The umbrella-shaped head 210 of the head assembly 200 has a cross groove 220 on the top and flat notches 230 on both sides. During installation, the appropriate fitting method can be selected according to different installation tools. For example, when using a screwdriver, the cross groove 220 can be used; when using a wrench, the flat notches 230 can be engaged with the wrench, and the screw can be turned by the tool for installation. When the screw is turned, the lead screw 120 of the screw assembly 100 is connected to the car dashboard. The threaded holes at the mounting points are screwed in to secure the car dashboard. Several sets of lead screws 120 can be provided. The annular groove 130 at the connection of each set of lead screws 120 can serve as a buffer and positioning tool. It can also be used for screw cutting and segmentation when needed. The bottom of the lower washer 310 and the top of the upper washer 320 of the anti-slip component 300 have anti-slip textures 350. The anti-slip textures 350 on the bottom of the lower washer 310 contact the mounting hole surface of the car dashboard, increasing the friction with the mounting hole surface. The anti-slip textures 350 on the top of the upper washer 320 contact the bottom of the umbrella-shaped head 210. At the same time, the upper teeth 340 on the bottom of the upper washer 320 and the lower teeth 330 on the surface of the lower washer 310 mesh with each other, further preventing the screw from loosening and improving the stability of the fixation.
