Description

Technical Field

[0001] This utility model relates to the field of mechanical assembly technology, and in particular to a combined multi-purpose strong magnetic sleeve magnetic connector reinforced bit. Background Technology

[0002] A socket extension bar is a transmission component used to connect power tools to various operating end parts such as sockets and screwdriver bits. Its function is to effectively transmit torque and assist in standard operations such as tightening and turning. It is commonly used in equipment such as electric wrenches and drills, playing a crucial bridging role between tools and accessories to meet different construction needs.

[0003] Existing socket extension rod structures generally have limited functionality, making it difficult to meet the needs of switching between multiple working conditions and components. Some traditional structures only support fixed-size socket connections. When switching working modes is required, users often have to replace the entire tool set or connectors to achieve functional conversion, greatly reducing efficiency. The lack of bit connection functionality and the single locking method, which cannot simultaneously accommodate dual locking of the socket and bit, easily leads to unstable connections or detachment during use, failing to meet the dual requirements of reliability and multi-functionality in complex working environments. Utility Model Content

[0004] The technical problem this utility model aims to solve is that existing sleeve connecting rods have a simple structure, are inconvenient to separate and convert, and are difficult to meet the practical needs of integrated, multi-mode rapid conversion.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a combined multi-purpose strong magnetic sleeve magnetic connecting rod reinforced bit, including a double-ended sleeve and a dual-function connecting rod. The small end and large end of the double-ended sleeve are respectively provided with H1 / 4-inch internal hexagonal holes and H5 / 16-inch internal hexagonal holes, and its outer wall is machined with an H10 specification external hexagonal structure; end A is the working end of the sleeve, which is provided with an H1 / 4-inch external hexagonal structure. A neodymium iron boron magnet is embedded in the top of the external hexagon, and a ball retaining groove is provided on its outer periphery for mechanical locking of a steel ball fixed on one side of the dual-function connecting rod; end B is the working end of the bit, which is an H1 / 4-inch drive head. The bottom end is provided with an integrated Phillips head bit, and a ball retaining groove matching the power tool is provided behind it. A locking steel ball is embedded in the corresponding position of the rod body;

[0006] As a further improvement of this utility model, the length of the B end of the dual-function connecting rod is greater than 28mm.

[0007] As a further improvement of this utility model, the double-headed sleeve has an auxiliary slot on its inner wall. The slot is 3.0 mm wide, 0.65-0.75 mm deep, and 9.5 mm from the end face. It cooperates with the steel ball at end B to achieve locking.

[0008] As a further improvement of this utility model, the distance between the steel ball and the top of the crosshead screwdriver bit is 19.2±0.5mm, and the protrusion is 0.4mm.

[0009] As a further improvement of this utility model, the outer ring of the double-headed sleeve is provided with two gripping ring grooves 1e.

[0010] As a further improvement of this utility model, the total length of the double-headed sleeve is set to 19mm.

[0011] The beneficial effects of this utility model are as follows: The double-ended structure of the sleeve and the double-ended setting of the connecting rod enable integrated conversion between the bit and the sleeve, allowing for rapid switching and instant dual-mode switching; the triple structure of magnetic attraction, ball-locking groove, and steel ball auxiliary groove ensures stable connection and prevents detachment, achieving multi-point mechanical locking; the sleeve can also be reversed to serve as a bit handle when used as a working tool, reducing the variety and size of tools, making it suitable for vehicle and outdoor use; furthermore, being made of S2 alloy steel, it ensures strength while meeting the torque requirements of power tools, making it widely applicable.

[0020] This utility model provides the following: Figure 1-4 As shown, a combined multi-purpose strong magnetic sleeve and magnetic connecting rod reinforced screwdriver bit includes a double-ended sleeve 1 and a dual-function connecting rod 2.

[0021] The double-ended socket 1 is made entirely of S2 alloy steel, with an overall torque performance of 25 N·m, suitable for use with power tools. The double-ended socket 1 has a total length of 19 mm, with H1 / 4 inch internal hexagonal holes 1a and H5 / 16 inch internal hexagonal holes 1b at the small and large ends respectively. Its outer wall is machined with an H10 external hexagonal structure 1c. The double-ended socket 1 has an auxiliary locking groove 1d on its inner wall, with a width of 3.0 mm, a depth of 0.65-0.75 mm, and a distance of 9.5 mm from the end face, which engages with the steel ball 6 at end B to achieve locking. The outer circumference of the double-ended socket 1 has two gripping grooves 1e for easy gripping.

[0022] As attached Figure 1 , 4 As shown, end A of the dual-function extension rod 2 is the socket working end, equipped with an H1 / 4-inch external hexagonal structure 2a. A neodymium iron boron magnet 3 is embedded at the top of the external hexagon, and a ball retaining groove is provided on its outer periphery for mechanical locking of the steel ball 4 fixed on one side of the dual-function extension rod. End B is the bit working end, an H1 / 4-inch drive head 2b, with an integrated Phillips head bit 2c at the bottom. A ball retaining groove 5 matching the power tool is provided behind it, and a locking steel ball 6 is embedded in the corresponding position on the rod body. The length of the rod body at end B of the dual-function extension rod 2 is greater than 28mm to prevent the socket from covering the bit. The distance between the steel ball 26 and the top of the Phillips head bit 2c is 19.2±0.5mm, and the protrusion is 0.4mm; to ensure locking fit accuracy.

[0023] Working principle: In specific implementation, this utility model has four working modes. Mode 1, sleeve H5 / 16 mode: The large end of the sleeve, H5 / 16 inch internal hexagonal hole 1b, is connected to the end 2a of the connecting rod A. It is attracted by magnet 3 and locked by steel ball 4 being inserted into the ball slot.

[0024] Mode 2, Sleeve H1 / 4 mode: The small end 1a of the double-headed sleeve 1 is sleeved to the end 2a of the connecting rod A, and is also locked by magnetic attraction and steel ball locking groove structure;

[0025] Mode 3, cross-shaped batching operation mode: The double-headed sleeve 1 is inserted into the position of the rod body at the end of the connecting rod B, and the steel ball 2 6 is locked by the auxiliary slot 1d added in the inner hole of the sleeve.

[0026] Mode 4, external hexagonal operation mode: The double-ended socket 1 is fitted into end A and locked by steel balls. The external H10 external hexagonal structure 1c is used to match the wrench for operation.

[0027] Furthermore, the sleeve is forged from S2 alloy steel, with H1 / 4-inch internal hexagonal holes 1a and H5 / 16-inch internal hexagonal holes 1b machined first, and H10 external hexagonal structure 1c machined on the outer wall.
