[0028] It should be noted that in the internal components of small electronic devices such as mobile phones and tablets, this kind of fastening wave bead screw has obvious advantages in installation convenience. Due to the compact internal space of electronic devices and the high precision requirement of component installation, this screw can adjust the length through the installation mechanism 3 to adapt to different installation depth requirements, avoiding installation problems caused by too long or too short screws. At the same time, the reinforcing mechanism 4 can ensure that the screw will not loosen when the device is subjected to vibration or impact, ensuring the stability and reliability of the device.

The installation mechanism 3 of this screw allows users to easily adjust the length of the screw, even without professional tools, making installation easy. The reinforcing mechanism 4 ensures that the furniture will not loosen during long-term use, ensuring the structural stability of the furniture and improving the user experience.

[0030] As a further improvement of the utility model, the outer side of the pulling plate 33 is provided with a reinforcing mechanism 4, the reinforcing mechanism 4 includes a threaded pipe 41, the threaded pipe 41 is internally threadedly connected with a screw rod 42, the bottom of the screw rod 42 is fixedly connected with an extrusion rod 43, the bottom of the pulling plate 33 is fixedly connected with a stable pipe 44, the inside of the stable pipe 44 is movably clamped with a connecting rod 45, the bottom of the connecting rod 45 is fixedly connected with a positioning plate 46, and the connecting rod 45 is fixedly connected with a return spring 47.

[0032] Meanwhile, the contents not described in detail in this specification all belong to the existing technology known to those skilled in the art.

[0033] Working principle: the clamping rod 37 is in the first positioning hole 34, because the compression spring 38 is in the initial compression state, generating elastic force, tightly pressing the clamping rod 37 in the first positioning hole 34, so that the relative position of the moving rod 32 and the movable tube 31 is fixed, when the overall length of the screw needs to be adjusted, pull the pull plate 33, the pull plate 33 drives the moving rod 32 to move upwards in the movable tube 31. During the movement, the clamping rod 37 will move in the guide pipe 36, and at the same time the compression spring 38 will be further compressed. When the moving rod 32 moves to the appropriate position, that is, the second positioning hole 35 is aligned with the clamping rod 37, the compression spring 38 restores the deformation, and pushes the clamping rod 37 into the second positioning hole 35, at this time the new relative position of the moving rod 32 and the movable tube 31 is fixed again, so as to realize the adjustment of the overall length of the screw, so as to adapt to different installation requirements, align the screw body 1 of the adjusted length with the installation position, rotate the screw body 1, and the bottom ball 2 can roll on the installation surface, reducing the friction, so that the screw is more smoothly rotated into the installation position;

[0034] Rotate the screw rod 42 in the threaded pipe 41, because the screw rod 42 and the threaded pipe 41 are threadedly connected, the screw rod 42 will move downwards along the threaded pipe 41, and in turn drive the extrusion rod 43 to move downwards. The extrusion rod 43 is movably connected above the positioning plate 46 at the bottom, so the extrusion rod 43 will exert downward pressure on the positioning plate 46, and the positioning plate 46 is movably connected below the pull plate 33 through the connecting rod 45 and the stable pipe 44. When the positioning plate 46 is pressed by the extrusion rod 43, the connecting rod 45 will move downwards in the stable pipe 44, and at the same time the return spring 47 is compressed. The positioning plate 46 is tightly pressed against the surface of the object to be fastened, and the friction and pressure are increased to prevent the screw from loosening and improve the fastening effect of the screw. If the screw needs to be disassembled, the screw rod 42 is rotated in the opposite direction, so that the extrusion rod 43 moves upwards, the return spring 47 restores the deformation, drives the positioning plate 46 and the connecting rod 45 to move upwards, and the pressure on the object to be fastened is released, facilitating the disassembly of the screw.
