quick-release screwdriver tip

Abstract

This invention provides a quick-release screwdriver bit structure, primarily for screwdriver bit assembly. The screwdriver bit has multiple engaging parts on its outer periphery, comprising: an outer tube, a rod passing through a hole in the outer tube, a limiting member, a sliding sleeve, and an anti-disengagement member. The rod has an assembly hole and a first end. The outer periphery of the first end forms staggered assembly parts and two side assembly parts. The limiting member is partially housed in the assembly parts and partially housed in the two side assembly parts. The part housed in the assembly parts has a portion passing through the assembly hole, while the other portion is exposed outside the assembly hole. The sliding sleeve slides on the first end and has a stop. By displacing the sliding sleeve, the stop pushes against the portion of the limiting member housed in the assembly part and exposed outside the assembly hole, selectively releasing the engagement of the screwdriver bit and the limiting member, thereby completing the screwdriver bit assembly and release.

Claims

1. A quick-release screwdriver bit structure, mainly for inserting a screwdriver bit, wherein the screwdriver bit has a plurality of engaging portions arranged around its outer periphery at intervals, comprising: an outer tube having a through hole extending from one end to the other; a rod having a portion passing through the through hole, the rod having an assembly hole extending from one end to the other, a first end exposed outside the through hole, the outer periphery of the first end having an assembly portion and two side assembly portions, the assembly portion and the two side assembly portions being alternately connected, and the assembly portion communicating with the assembly hole; a limiting member having a portion housed in the assembly portion, another portion of the limiting member housed in the two side assembly portions, the portion of the limiting member housed in the assembly portion having a portion passing through the assembly hole, and the other portion exposed outside the assembly hole; A sliding sleeve, slidably mounted at the first end and covering the assembly portion, the two side assembly portions, and the limiting member, wherein at least one stop is protruding from the inner wall surface of the sliding sleeve, and the at least one stop is driven by the sliding sleeve to move and abut against the portion of the limiting member exposed in the assembly hole; and an anti-detachment member, assembled at the end of the first end and moving against the sliding sleeve. When the sliding sleeve is close to the anti-disengagement component and the screwdriver bit is inserted into the assembly hole, the portion of the limiting member located in the assembly part is engaged with at least one engaging portion of the screwdriver bit; conversely, when the screwdriver bit is pulled out of the assembly hole, the sliding sleeve moves toward the outer tube body, and the at least one stop block inside the sliding sleeve abuts against the portion of the limiting member exposed in the assembly hole, causing the limiting member to disengage from the engaging portion of the screwdriver bit.

2. The quick-release screwdriver tip structure as described in claim 1, wherein, The limiting member further has a closed section and two open sections, one end of each of the two open sections being connected to the closed section.

3. The quick-release screwdriver tip structure as described in claim 1, wherein, Each of the two assembly parts further has a stop portion. When the sliding sleeve does not shift and the screwdriver head is pulled away in the opposite direction to the outer tube, the limiting member moves and abuts against each stop portion.

4. The quick-release screwdriver tip structure as described in claim 2, wherein, The closed section further includes a horizontal bar and two vertical sections. The two ends of the horizontal bar are connected to the two vertical sections respectively, and the other ends of the two vertical sections are connected to the corresponding open sections respectively.

5. The quick-release screwdriver tip structure as described in claim 4, wherein, At the connection between the horizontal bar and the two vertical parts, a plurality of pushing and abutting parts are further formed. Each pushing and abutting part is exposed in the assembly hole. When the sliding sleeve slides toward the outer tube, each pushing and abutting part moves and abuts against the at least one stop block.

6. The quick-release screwdriver tip structure as described in claim 1, wherein, The rod body has a second end on the side opposite to the first end, and is provided with a connector. The connector is movably connected at one end through the second end into the assembly hole, and is movably connected at the other end to a gripping structure.

7. The quick-release screwdriver tip structure as described in claim 1, wherein, The assembly part further has a mounting hole that communicates with the assembly hole, and the two side assembly parts each have a mounting groove, one end of each mounting groove having an opening, and each opening communicating with the mounting hole.

8. The quick-release screwdriver tip structure as described in claim 4, wherein, The crossbar section and the two open sections are located on different horizontal planes.

9. The quick-release screwdriver tip structure as described in claim 6, wherein, A magnetic suction assembly is provided, which is disposed in the assembly hole. The magnetic suction assembly includes a base, a magnetic suction element and an elastic body. The base has a first mounting hole and a second mounting hole. The magnetic suction element is disposed in the first mounting hole, and a portion of the elastic body passes through the second mounting hole. The two ends of the elastic body respectively spring against the base and the connector.

10. The quick-release screwdriver tip structure as described in claim 1, wherein, The outer surface of the slide sleeve is further provided with an anti-slip texture.
