[0024] Specifically, the positioning component 2 includes a connecting seat 21, a support rod 22, a positioning slide rod 23, a positioning plate 24, a hammering block 25, and a fixing component 26. One end of the lower part of the screw head 1 is sleeved with the connecting seat 21. The support rod 22 is arranged above the connecting seat 21. One end of the support rod 22 is slidably provided with the positioning slide rod 23. The positioning plate 24 is arranged below the positioning slide rod 23. The hammering block 25 is arranged above the positioning slide rod 23. The fixing component 26 is arranged at the connection between the screw head 1 and the connecting seat 21.

[0025] By adopting the above technical solution, the connecting seat 21 is sleeved on one end of the screw head 1 and then fixed by the fixing component 26. After the screw rod 6 is fixed, the hammering block 25 is hammered. Under the action of the positioning slide rod 23, the positioning plate 24 will be driven to move downward and insert into the object, thereby improving the stability of the screw. When the device is in use, after the screw rod 6 is completely inserted into the object, the screw can be positioned, improving the stability during use and the anti-pulling effect.

[0026] Specifically, the fixing component 26 includes a fixing screw 261, a fixing block 262, a bearing 263, a guiding slider 264, and a fastening pad 265. One end of the connecting seat 21 is threadedly connected with the fixing screw 261. One end of the fixing screw 261 is provided with the fixing block 262. The bearing 263 is arranged at the connection between the fixing screw 261 and the fixing block 262. The guiding slider 264 is arranged above the fixing block 262. The fastening pad 265 is arranged at one end of the fixing block 262 away from the fixing screw 261.

[0027] By adopting the above technical solution, when the fixing component 26 is in use, the fixing screw 261 is rotated. As the fixing screw 261 rotates, under the action of the bearing 263 and the guiding slider 264, the fixing block 262 will be driven to move and cooperate with the fastening pad 265 to fix between the connecting seat 21 and the screw head 1.

[0028] Specifically, one end of the fixing screw 261 is provided with a rotating block, and anti-slip blocks are symmetrically arranged on the surface of the rotating block.

[0029] By adopting the above technical solution, the arrangement of the rotating block and the anti-slip blocks enables the fixing screw 261 to be rotated conveniently.

[0030] In the use of this embodiment: The connecting seat 21 is sleeved on one end of the screw head 1 and then fixed by the fixing component 26. After the screw rod 6 is fixed, the hammering block 25 is hammered. Under the action of the positioning slide rod 23, the positioning plate 24 will be driven to move downward and insert into the object, thereby improving the stability of the screw. When the fixing component 26 is in use, the fixing screw 261 is rotated. As the fixing screw 261 rotates, under the action of the bearing 263 and the guiding slider 264, the fixing block 262 will be driven to move and cooperate with the fastening pad 265 to fix between the connecting seat 21 and the screw head 1. When the device is in use, it is convenient to position the screw after the screw rod 6 is completely inserted into the object, improving the stability of use and the anti-pulling effect.

[0031] Embodiment 2

[0032] The difference between this embodiment and Embodiment 1 is as follows: Specifically, the clamping component 5 includes an extrusion block 51, a clamping spring 52, a clamping block 53 and a limiting slider 54. Among them, the extrusion block 51 is arranged inside the cover plate 4, one end of the extrusion block 51 is provided with the clamping spring 52, the other end of the extrusion block 51 is provided with the clamping block 53, and the limiting sliders 54 are arranged on both sides of the clamping block 53.

[0033] By adopting the above technical solution, when the cover plate 4 is sleeved on the screw head 1, the screw head 1 abuts against the clamping block 53. Under the action of the guiding sliding opening, the clamping block 53 will be driven to move, so that the extrusion block 51 moves to compress the clamping spring 52, thereby completing the clamping and fixing of the cover plate 4 and the screw head 1. When the device is in use, it is convenient to fix the cover plate 4 and the screw head 1 and improve the stability between them.

[0034] Specifically, a guiding sliding opening is formed on one side of the clamping block 53, and a stable sliding rod 55 slides in the middle of the limiting slider 54.

[0035] By adopting the above technical solution, the guiding sliding opening facilitates the screw head 1 to drive the clamping block 53 to automatically move to one side when the cover plate 4 is sleeved on the screw head 1, and the stable sliding rod 55 facilitates the stable sliding of the clamping block 53.

[0036] In the use of this embodiment: When the cover plate 4 is sleeved on the screw head 1, the screw head 1 abuts against the clamping block 53. Under the action of the guiding sliding opening, the clamping block 53 will be driven to move, so that the extrusion block 51 moves to compress the clamping spring 52, thereby completing the clamping and fixing of the cover plate 4 and the screw head 1. When the device is in use, it is convenient to fix the cover plate 4 and the screw head 1 and improve the stability between them.

[0037] The structures and operating principles of the screw rod 6 and the external thread 7 in the present utility model have been disclosed in a pull-resistant screw with a stable structure, with a Chinese patent application number of 202321953014.6. Its operating principle is that through the cooperation of the screw rod 6 and the external thread 7, it enters the object for fixation.

[0038] The operating principle and usage process of the present utility model: When using the present utility model, the screw rod 6 is rotated into the object through the hexagonal rotation groove 3 and the external thread 7. After the rotation is completed, positioning is carried out through the positioning component 2, thereby improving the pull-resistant effect. Finally, the cover plate 4 is sleeved on the screw head 1 and clamped firmly through the clamping component 5. When the positioning component 2 is in use, the connecting seat 21 is sleeved on one end of the screw head 1 and then fixed through the fixing component 26. When the screw rod 6 is fixed, the hammering block 25 is hammered. Under the action of the positioning slide rod 23, it will drive the positioning plate 24 to move downward and insert into the object, thereby improving the stability of the screw. When the fixing component 26 is in use, the fixing screw 261 is rotated. As the fixing screw 261 rotates, under the action of the bearing 263 and the guiding slider 264, it will drive the fixing block 262 to move and cooperate with the fastening pad 265 to fix between the connecting seat 21 and the screw head 1, making the device, when in use, facilitate the positioning of the screw rod 6 after it is completely inserted into the object, improving the stability during use and the pull-resistant effect. When the clamping component 5 is in use, when the cover plate 4 is sleeved on the screw head 1, the screw head 1 abuts against the clamping block 53. Under the action of the guiding slide opening, it will drive the clamping block 53 to move, causing the extrusion block 51 to move and compress the clamping spring 52, thereby completing the clamping and fixing of the cover plate 4 and the screw head 1, making the device, when in use, facilitate the fixing of the cover plate 4 and the screw head 1 and improving the stability between them.
