Description

Technical Field

[0001] The utility model relates to a screwdriver bit. Background Art

[0002] The current prior art is Chinese Patent 201020665915.1. The utility model relates to a screwdriver bit with a magnetic ring. The screwdriver bit as a whole is divided into a handle, a collar and a screwdriver head in sequence. The magnetic ring is mounted on and fixed to the collar of the screwdriver bit, and the screwdriver head passes through the magnetic ring. The inner diameter of the magnetic ring is slightly larger than the outer diameter of the collar, and the length of the magnetic ring is slightly shorter than the length of the collar, so that when the screwdriver head is inserted into the groove of the screw head, there is still a gap between the magnetic ring and the screw head. By changing the shape of the blade at the end of the screwdriver head, the screwdriver bit can be used for a variety of screws, especially steel frame sheet metal screws. The problem is that the magnetic ring is fixed to the neck, and the bit that is not applied to the screwdriver head cannot be used. Utility Model Content

[0003] The utility model aims to provide a screwdriver bit with a magnetic ring, which has the characteristics of convenient disassembly and assembly.

[0004] The utility model is realized as follows: a screwdriver bit with a magnetic ring comprises a handle, a neck, a head and a magnetic ring, and the special feature is that a sliding limit groove is provided on the neck.

[0005] It also includes an annular rubber ring and a tube body made of a magnetic conductive metal material, one end of the tube body is provided with a countersunk hole, and the other end is provided with an interface pipe.

[0006] The annular rubber ring is fixed in the countersunk hole, and the interface tube is inserted into the center hole of the magnetic ring for magnetic connection. The annular rubber ring, the tube body and the magnetic ring constitute a magnetic attraction component. The annular rubber ring is slidably matched and positioned with the neck in the sliding limit groove, and the tube body is slidably matched with the neck and is detachable.

[0007] The screwdriver bit with a magnetic ring is special in that one end of the head adjacent to the neck is located in the interface tube.

[0008] The screwdriver bit with a magnetic ring is special in that the magnetic suction components can be disassembled or assembled together.

[0009] The screwdriver bit with a magnetic ring is special in that the inner diameter of the magnetic ring is smaller than the diameter of the screw head, and the outer diameter is greater than or equal to the diameter of the screw head.

[0010] The utility model discloses a screwdriver bit with a magnetic ring. The annular rubber ring, a tube body and the magnetic ring form a magnetic attraction component, which is convenient to assemble and disassemble from the neck and is suitable for bits with different heads. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0014] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0015] like Figure 1 As shown, a screwdriver bit with a magnetic ring 2 comprises a handle 11, a neck 12, a head 13 and the magnetic ring 2, wherein the neck 12 is provided with a sliding limit groove 121.

[0016] It also includes an annular rubber ring 3 and a tube body 4 made of a magnetic conductive metal material, one end of the tube body 4 is provided with a countersunk hole 41, and the other end is provided with an interface pipe 42, and the tube body 4 is made of a metal iron material;

[0017] The annular rubber ring 3 is fixed in the countersunk hole 41, and the interface tube 42 is inserted into the center hole of the magnetic ring 2 for magnetic connection. The annular rubber ring 3, the tube body 4 and the magnetic ring 2 constitute a magnetic attraction component. The annular rubber ring 3 is slidably matched and positioned with the neck in the sliding limit groove 121, and the tube body 4 is slidably matched with the neck 12.

[0018] like Figure 1 , Figure 2 As shown, in the use state, the end of the head 13 adjacent to the neck 12 is located in the interface tube, and the screw head is attracted to the magnetic ring; in the static state, Figure 1 In this state, the magnetic attraction component moves to the right, and the head is retracted into the tube body 4 to protect the head 13.

[0019] The tube body 4, the annular rubber ring 3 and the magnetic ring 2 are disassembled or assembled together. With such a structure, the magnetic suction assembly can be applied to screwdriver bits with different shapes of heads, such as a cross, a rice shape or a straight shape.

[0020] The inner diameter of the magnetic ring 2 is smaller than the diameter of the screw head, and the outer diameter is greater than or equal to the diameter of the screw head.

[0021] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
