[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 This utility model provides an embodiment: a deep screw tightening tool, including a handle 1, an anti-slip groove 2 inside the handle 1, and anti-slip protrusions 3 fixed on the surface of the handle 1. Several anti-slip protrusions 3 are provided and are evenly distributed on the surface of the handle 1, which greatly increases the friction when people hold the handle 1 and makes the grip more stable. A guide tube 4 is installed on one side of the handle 1. A groove 15 is provided inside the guide tube 4, and an extension rod 7 is movably installed inside the groove 15. A hexagonal tool head 8 is installed on one side of the extension rod 7. A hole 6 is provided at the top of the guide tube 4, and a limit screw 5 is movably installed inside the hole 6. The cross-section of the extension rod 7 is smaller than the cross-section of the guide tube 4. The extension rod 7 forms a sliding structure with the guide tube 4 through the groove 15, which allows the extension rod 7 to be smoothly pulled and adjusted.

[0023] Specifically, such as Figure 1 and Figure 2As shown, when it is necessary to tighten the screws deep inside, pry open the sealing cover 23 to open the slot 20, then pinch the pull ring 24 to pull the handle 19 out of the storage slot 17, then hold the handle 19 and use the cutter head 18 to tighten the limiting screw 5 to open the limit on the extension rod 7, pull the extension rod 7 to the right to adjust to the appropriate length, and then turn the limiting screw 5 in the opposite direction to limit and lock the extension rod 7.

[0024] A storage groove 17 is provided on one side inside the handle 1. A protective rubber 16 is fixed on one side inside the storage groove 17. A handle 19 is movably arranged inside the storage groove 17. A blade head 18 is fixed on the right side of the handle 19. A pull ring 24 is fixed on the left side of the handle 19. A slot 20 is provided on the left side inside the storage groove 17. A rubber connecting strip 21 is fixed to one end of the slot 20. A sealing cover plate 23 is fixed to one end of the rubber connecting strip 21. A sealing plug 22 is fixed on one side of the sealing cover plate 23. The cross-section of the sealing plug 22 is smaller than the cross-section of the slot 20. The sealing plug 22 and the slot 20 form an engaging structure. The cross-section of the handle 19 is smaller than the cross-section of the storage groove 17. The handle 19 and the storage groove 17 form an engaging structure. The blade head 18 can be stored away when not in use and can move with the movement of the twisting tool.

[0025] Specifically, if Figure 1 and Figure 2 As shown, when the twisting tool is in use, the handle 19 and the blade 18 are hidden inside the storage slot 17. When adjusting the depth of use of the twisting tool, it can be taken out as needed, making it more convenient to use.

[0026] The hexagonal tool head 8 has a cross tool head 14 and a flat tool head 13 at its two ends. A cross mounting block 12 is fixed to the left side of the hexagonal tool head 8, the cross tool head 14 and the flat tool head 13, and a magnetic post 10 is fixed to the left side of the cross mounting block 12. A metal groove 11 is provided on the right side inside the extension rod 7, and a mounting groove 9 is provided on one side of the metal groove 11. The cross mounting block 12 and the mounting groove 9 form a locking structure, and the magnetic post 10 and the metal groove 11 form a locking structure. The locking structure design allows the tool head to be stably installed inside the extension rod 7.

[0027] Specifically, if Figure 2 , Figure 3 and Figure 4 As shown, the tool head is replaced according to the type of screw being tightened. When replacing, pull the hexagonal tool head 8 to one side to remove it. Then, according to the actual needs, take the Phillips head 14 or the flathead head 13 and push the magnetic column 10 on one side into the metal groove 11 inside the extension rod 7 to install it for use.

[0028] Working principle: In use, this utility model allows you to use the screw-tightening tool to tighten screws on the surface of an object. The tool head can be changed depending on the type of screw being tightened. To change the head, pull the hexagonal tool head 8 to one side to separate the magnetic post 10 from the metal groove 11, allowing the cross-shaped mounting block 12 to move out of the mounting groove 9. Then, depending on the actual needs, take the cross-shaped tool head 14 or the flathead tool head 13 and push the magnetic post 10 into the metal groove 11 inside the extension rod 7 for installation. If further adjustments are needed... When tightening the screws deep inside, pry open the sealing cover 23 to open the slot 20, then pinch the pull ring 24 to pull the handle 19 out of the storage slot 17. Then, hold the handle 19 and use the cutter head 18 to tighten the limiting screw 5 to open the limit on the extension rod 7. Pull the extension rod 7 to the right to adjust it to a suitable length, then turn the limiting screw 5 in the opposite direction to limit and lock the extension rod 7. Then, insert the cutter head 18 back into the original position, fasten the sealing cover 23 to lock the slot 20, and hide the handle 19. Finally, use the tightening tool of the adjusted length to tighten the corresponding screws.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
