[0023] The embodiment of the present application provides an anti-slip screwdriver, which effectively solves the problem that the handle and the palm of the above-mentioned screwdriver are prone to slip relative to each other when in use, which not only makes the handle easy to separate from the palm, but also may cause friction damage to the palm while slipping. Through the design of the handle and the anti-slip strip, when the user holds the handle and rotates it, a certain force will be generated between the user's hand and the handle, so the user's hand will slide slightly along the anti-slip strip. At this time, the force will push the handle to resist the screw, thereby achieving a self-fixing effect. Moreover, through the design of the anti-slip strip, the anti-slip strip will support the user when rotating the handle, thereby achieving an anti-slip effect.

[0024] Example

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application is to effectively solve the technical problem that the handle and the palm of the above-mentioned screwdriver are easy to slip relative to each other when in use, which not only makes the handle easy to separate from the palm, but also may cause friction damage to the palm while slipping. The overall idea is as follows: an anti-slip screwdriver includes an anti-slip mechanism and an adjustment mechanism. The anti-slip mechanism includes a grip 11 and anti-slip strips 21. Three anti-slip strips 21 are evenly and equidistantly fixed on the grip 11. Streamlined chamfers are provided on both side walls of the anti-slip strips 21. When in use, the screwdriver head 15 can be aligned with the screw, and then The handle 11 can be rotated later, and the anti-slip strip 21 will support the hand when the handle 11 is rotated. Since the anti-slip strip 21 is designed to be streamlined, when the user holds the handle 11 and rotates it, a certain force will be generated between the user's hand and the handle 11, so the user's hand will slide slightly along the anti-slip strip 21. At this time, the force will push the handle 11 to contact the screw, achieving a self-fixing effect. In addition, through the design of the anti-slip strip 21, the anti-slip strip 21 will support the user when the handle 11 is rotated, thereby achieving an anti-slip effect.

[0026] The adjustment mechanism includes a limit groove 13, a threaded ring 14, a screwdriver bit 15 and a limit block 16. The two limit grooves 13 are symmetrically arranged on the connecting column 12. The screwdriver bit 15 is slidably installed inside the connecting column 12. The two limit blocks 16 are symmetrically fixedly installed on the screwdriver bit 15. The threaded ring 14 is threadedly installed on the connecting column 12. A circular groove is arranged inside the connecting column 12. The screwdriver bit 15 is slidably installed in the circular groove. An inner groove 17 is arranged inside the threaded ring 14. The two limit blocks 16 are arranged in the inner groove 17. A fixed plate 22 is fixedly installed on the handle 11. The side of the fixed plate 22 close to the handle 11 is concave. Lamp beads 23 are evenly and equidistantly installed inside the fixed plate 22, so that efficient lighting effects can be achieved in places with poor light. Since the installation requirements of screws at different positions are different, when the length of the screwdriver bit 15 needs to be adjusted, the threaded ring 14 can be rotated on the connecting column 12. The rotation of the threaded ring 14 will drive the two limit blocks 16 to slide outward inside the two limit grooves 13. At this time, the two limit blocks 16 will drive the screwdriver bit 15 to slide outward inside the connecting column 12, thereby completing the adjustment of the length of the screwdriver bit 15, making it suitable for different working conditions, thereby enhancing its applicability.

[0027] In view of the problems existing in the prior art, the utility model provides an anti-slip screwdriver. Through the design of the handle 11 and the anti-slip strip 21, when the user holds the handle 11 and rotates it, a certain force will be generated between the user's hand and the handle 11, so the user's hand will slide slightly along the anti-slip strip 21. At this time, the force will push the handle 11 to contact the screw, thereby achieving a self-fixing effect. Moreover, through the design of the anti-slip strip 21, the anti-slip strip 21 will support the user when rotating the handle 11, thereby achieving an anti-slip effect.

[0028] Working principle:

[0029] In the first step, when using, the screwdriver bit 15 can be aligned with the screw, and then the handle 11 can be rotated. When the handle 11 is rotated, the anti-slip strip 21 will support the hand. Since the anti-slip strip 21 is designed to be streamlined, when the user holds the handle 11 and rotates it, a certain force will be generated between the user's hand and the handle 11, so the user's hand will slide slightly along the anti-slip strip 21. At this time, the force will push the handle 11 to contact the screw, achieving a self-fixing effect. In addition, through the design of the anti-slip strip 21, the anti-slip strip 21 will support the user when the handle 11 is rotated, thereby achieving an anti-slip effect.

[0030] In the second step, due to different installation requirements of screws at different positions, when the length of the bit 15 needs to be adjusted, the threaded ring 14 can be rotated on the connecting column 12. The rotation of the threaded ring 14 will drive the two limit blocks 16 to slide outward inside the two limit grooves 13. At this time, the two limit blocks 16 will drive the bit 15 to slide outward inside the connecting column 12, thereby completing the adjustment of the length of the bit 15, making it suitable for different working conditions and enhancing its applicability.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
