Multifunctional bolt turning tool ratchet handle

Abstract

The invention relates to a multifunctional bolt turning tool ratchet handle, in particular to a multi-head multifunctional bolt turning tool ratchet handle which can rotate with 360 DEG and can be used as both screwdriver handle and sleeve spanner handle. The multifunctional bolt turning tool ratchet handle comprises a ratchet part, a handle body and a hand holding part, wherein the back end of the handle body is fixed with the hand holding part, the front end of the handle body is provided with the ratchet part capable of rotating with 360 DEG, the rotating central axis of the ratchet part is vertically intersected with the central axis of the handle, the outer edge of the ratchet part is distributed with a plurality of turning tool joints in radial shape, and the central axes of the turning tool joints and the central axis of the handle are in the same plane. The multifunctional bolt turning tool ratchet handle in the invention is combined with the ratchet bolt turning tool and the ratchet sleeve spanner in the existing technology together and is integrated with multiple specifications of bolt turning tool joints integrally to make up the defects in the existing technology, suchas single linking form, single using mode, limited angle adjusting, and inconvenient using and carrying.

Description

technical field [0001] The invention relates to a multifunctional screwdriver ratchet handle, in particular to a multi-functional screwdriver ratchet handle which can be used as both a screwdriver handle and a socket wrench handle with 360° rotatable multi-heads. Background technique [0002] Screws and bolts are very commonly used fasteners. According to international practice or national standards, usually the head of the screw adopts a concave in-line, cross, five-star, plum blossom and other screwing forms, and the head of the bolt adopts an outer shape. Convex hexagonal head or concave hexagonal pit and other screwing forms; therefore, people have configured various screwdrivers (commonly known as screwdrivers) and wrenches. Due to the variety of specifications, in order to be easy to carry, the single-head screwdriver has developed into a screwdriver handle with a replaceable bit head, and the wrench has developed into a socket wrench with a variable diameter. Then a ...

Problems solved by technology

[0003] 1. The connection form is single. The handle of the ratchet screwdriver is connected to the screwdriver head in the form of a hexagonal hole, and the handle of the ratchet sleeve is connected to the sleeve in the form of a square tenon.

[0004] 2. The purpose of the tool is single. The existing screwdriver cannot be used as a wrench. Similarly, the wrench cannot be used as a screwdriver. No matter which one of the above tools is used, it needs to be worn at the same time to adapt to the commonly used bit and socket.

First, it is troublesome to change tools during operation; second, the screw handle and socket wrench take up a large part of the tool bag

[0005] 3. The angle of rotation is limited. Although the ratchet screwdriver handle of the prior art can be adjusted to a certain angle, the adjusted angle does not exceed 90°
