Technical Field
[0001] This utility model relates to the field of screwdriver tip technology, and in particular to a multi-purpose screwdriver tip. Background Technology
[0002] Screwdrivers, as a common fastening tool, are widely used in various scenarios such as mechanical repair, equipment installation, and home assembly. Traditional screwdrivers usually consist of a fixed blade and a handle, and the blade type is limited. When dealing with different types of screws, it is necessary to frequently change different screwdrivers, which is not only cumbersome to operate, but also prone to the problem of not having all the necessary tools, thus affecting work efficiency.
[0003] While some multi-functional screwdrivers have emerged in the prior art, achieving multiple functions through detachable or rotatable heads, these products generally suffer from the following drawbacks: First, the blade switching mechanism of some products is complicated, requiring additional tools or multiple operations to complete the switching, which cannot meet the need for quick and convenient use. Secondly, the structural strength is insufficient. Due to unreasonable design, the connection between the cutter head and the main body is prone to stress concentration when subjected to force, which can easily lead to deformation or breakage after long-term use, affecting the service life.
[0004] Furthermore, screws are prone to falling off when tightening small screws or performing vertical operations, and existing tools lack effective suction or positioning structures, which increases the difficulty of operation. Utility Model Content
[0005] This utility model relates to a multi-purpose screwdriver bit, which solves the problems of some products having complicated bit switching mechanisms that require additional tools or multiple operations to complete the switching, thus failing to meet the need for quick and convenient use; and insufficient structural strength, where the connection between the bit and the main body is poorly designed and prone to stress concentration under force, which can easily lead to deformation or breakage after long-term use.
[0006] This utility model provides a versatile screwdriver bit, specifically including: a post; The main body of the column is a hexagonal stud structure. A reinforcing rod is welded to the upper and lower ends of the column. The upper and lower ends of the reinforcing rod are arc-shaped structures. Two sets of device slots are symmetrically opened on the outer end face of the column. A locking mechanism is installed inside the device slots. A Torx screwdriver, wherein the Torx screwdriver is fixedly installed on the outer end face of the reinforcing rod at the upper position; A flathead screwdriver, wherein the flathead screwdriver is fixedly installed on the outer end face of the reinforcing rod at the lower position; The locking block has a ring structure with a trapezoidal cross-sectional area, and a rubber strip is fixedly installed on the outer end face of the locking block.
[0007] Furthermore, the positioning mechanism includes: The sliding plate is slidably mounted inside the device slot, with its outer end face fitting against the inner end face of the device slot.
[0008] Furthermore, the positioning mechanism also includes: A connecting spring is located inside the slot of the device, and its outer end face is fixedly connected to the sliding plate. The limiting block is fixedly installed on the outer end face of the sliding plate, and the outer end face of the limiting block has an arc-shaped structure.
[0009] Furthermore, a first magnet is fixedly installed on the outer end face of the Torx screwdriver, and a second magnet is fixedly installed on the outer end face of the flathead screwdriver.
[0010] Furthermore, the outer end face of the column has two transverse slots, and the cross-sectional area of the transverse slots is trapezoidal.
[0011] Furthermore, the card block is engaged inside the transverse card slot, and a rubber strip is fixedly installed on the outer end face of the card block. The outer end face of the rubber strip has an arc-shaped structure.
[0012] This utility model provides a versatile screwdriver bit with the following advantages: 1. Torx screwdrivers and flathead screwdrivers are fixed to the reinforcing rods at the top and bottom of the column, respectively, to directly meet the turning needs of Torx screws and flathead screws. The outer end face of the Torx screwdriver is equipped with a first magnet, and the outer end face of the flathead screwdriver is equipped with a second magnet. The attraction between the magnets and the iron screws can be used to attract the screws and prevent them from falling off during operation.
[0013] 2. The two sets of device slots at the outer end of the column have built-in locking mechanisms. Under the elastic force of the connecting spring, the sliding plate drives the arc-shaped limiting block to protrude from the surface of the column. When the screwdriver head is inserted into the handle, the limiting block is squeezed and contracted. After being fully inserted, it springs back and locks into the slot on the inner wall of the handle, achieving quick fixation. When disassembling, applying a reverse pulling force can compress the connecting spring to retract the limiting block and complete the separation.
[0014] 3. A trapezoidal locking block is engaged in the horizontal slot at the outer end of the column. The arc-shaped rubber strip at the outer end of the locking block increases the friction with the handle and prevents slippage during use. Depending on the inner diameter of different handles, the compatibility can be further optimized and the operational stability enhanced by replacing the locking block with one of different thicknesses or adjusting its position in the horizontal slot. The reinforcing rod is fixed to the column by welding, and the arc-shaped structure at both ends distributes the force, avoiding stress concentration and deformation during tightening, thus improving the overall structural strength and adapting to high-torque operation scenarios.

Under the elastic force of the connecting spring 501, the sliding plate 5 drives the arc-shaped limiting block 502 to protrude from the surface of the column 1. When the screwdriver head is inserted into the handle, the limiting block 502 is compressed and contracted, waiting for… After full insertion, the spring rebounds and snaps into the inner wall slot of the handle for quick fixation. When disassembling, applying a reverse pulling force compresses the connecting spring 501, causing the limiting block 502 to retract and complete the separation. A trapezoidal locking block 4 is engaged in the transverse slot 102 at the outer end of the column 1. The arc-shaped rubber strip 401 at the outer end of the locking block 4 increases the friction with the handle and prevents slippage during use. Depending on the inner diameter of different handles, the compatibility can be further optimized and the operational stability enhanced by replacing the locking block 4 with one of different thicknesses or adjusting its position in the transverse slot 102. The reinforcing rod 101 is fixed to the column 1 by welding.
