Description

Technical Field

[0001] This utility model relates to the field of screwdriver rods, specifically an anti-slip screwdriver rod. Background Technology

[0002] Screwdrivers are indispensable tools in daily screw installation and removal. However, traditional screwdrivers have some obvious drawbacks in practical use:

[0003] Slippage of the handle: The connection between the screwdriver handle and the screwdriver body is relatively simple. When using it, especially when encountering greater resistance or requiring greater torque, the handle body is prone to slipping in the handle. This prevents the screwdriver from effectively transmitting rotational force, which not only reduces work efficiency but may also damage the screw or working surface, increasing work difficulty and cost.

[0004] Limited usage: Traditional screwdrivers can only be connected to the handle in a fixed manner, and the insertion position of the screw cannot be flexibly adjusted according to different work scenarios and operating spaces. This makes operation extremely inconvenient or even impossible when working at certain angles or in narrow spaces.

[0005] Non-replaceable screwdriver tips: Different types of screws require matching screwdriver tips. Traditional screwdrivers often only come with one type of tip. If you want to disassemble different types of screws, you need to prepare multiple screwdrivers with different tips, which is inconvenient to carry and manage, and increases tool costs and carrying burden. For this reason, we have proposed an anti-slip screwdriver handle. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides an anti-slip screwdriver handle, which solves the aforementioned problems.

[0007] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an anti-slip screwdriver shaft, comprising an integrally formed handle portion and a side protrusion portion, wherein the side protrusion portion is disposed on the side of the handle portion, and both the handle portion and the side protrusion portion have rod insertion holes for inserting a rod body at their ends, wherein multiple sets of arc-shaped notches are equidistantly formed on the outer wall surface of the rod body, and multiple sets of inner wall limiting protrusions are integrally formed equidistantly on the inner wall of the rod insertion hole, and a replaceable cutting head is provided at the end of the rod body.

[0008] Preferably, the rod insertion hole and the cross-section of the rod are hexagonal, the inner wall limiting protrusion is integrally formed on each plane inside the rod insertion hole, and the arc-shaped notch is formed on each plane on the surface of the rod.

[0009] Preferably, the end of the rod is integrally formed with a connecting end, the end of the connecting end is integrally formed with a plug-in end, the plug-in end has a blade insertion hole, and the replaceable blade has an integrally formed blade insertion part at the position corresponding to the blade insertion hole, the blade insertion part is inserted into the blade insertion hole.

[0010] Preferably, the cross-section of the blade insertion part and the blade insertion hole is hexagonal, and an arc-shaped notch is provided on the outer wall surface of the blade insertion part. An inner wall limiting protrusion is integrally formed on the inner wall of the blade insertion hole at the position corresponding to the arc-shaped notch, and the inner wall limiting protrusion is engaged with the blade insertion hole.

[0011] Preferably, the shape of the replaceable blade is any one of the following: a straight line, a cross, a star shape, a hexagonal head, or a plum blossom shape.

[0012] Preferably, multiple sets of circular grooves are equidistantly formed on the end face of the plug-in terminal, and magnets are installed inside the circular grooves.

[0013] Compared with the prior art, this utility model provides an anti-slip screwdriver handle, which has the following beneficial effects:

[0014] Enhanced stability of the rod insertion: Multiple sets of arc-shaped notches are formed on the outer wall of the rod, and multiple sets of inner wall limiting protrusions are integrally formed at equal intervals on the inner wall of the rod insertion hole. When the rod is inserted into the rod insertion hole, the arc-shaped notches and the corresponding inner wall limiting protrusions interlock, preventing the rod from slipping during rotation. This greatly improves the stability of the connection between the rod and the handle and the side protrusions, ensuring effective torque transmission during operation, improving work efficiency, and avoiding screw damage or work errors caused by slippage.

[0015] Flexible Usage: The screwdriver features insertion holes on both the handle and the side protrusions, allowing users to adjust the insertion position based on their needs, such as workspace size and ease of operation. For example, in confined spaces, the screwdriver can be inserted into the side protrusion's insertion hole for a more suitable operating angle, thus expanding its application scenarios and enhancing its versatility.

[0016] Easy-to-change screwdriver tips: The replaceable tip design allows the screwdriver to accommodate various types of screws. The tip insertion part and tip insertion hole feature a hexagonal cross-section design and are secured by two arc-shaped notches and two inner wall limiting protrusions, ensuring a stable connection. When needing to remove different types of screws, simply pull the replaceable tip from the end of the shaft, replace it with the appropriate tip, and insert it. This eliminates the need to carry multiple screwdrivers with different tips, improving tool versatility, reducing costs, and simplifying tool carrying.

[0017] To prevent the blade from falling off: Multiple sets of circular grooves are evenly spaced on the end face of the connector, each containing a magnet. When the blade connector is inserted into the connector hole, the magnet attracts the end face of the replaceable blade. This ensures that even when the rod is lifted vertically, the replaceable blade inserted at the bottom will not fall off due to gravity, further enhancing stability and convenience during use and preventing accidental loss or damage to the blade.
