Embodiment Construction

[0022] Refer to attached drawings. The connecting tool of the nut and the bolt provided by the present invention can be applied to the bolt head 1 with twelve teeth, the bolt head 2 with the hexagonal shape, the bolt head 3 with the square shape, the plum-shaped bolt head 4 with the twelve protruding shape, The hexagonal bolt head 5 with six protruding shapes can also be used for 12-tooth nut, hexagonal nut, square nut, hexagonal nut with 12-point protrusion, and hexagonal protrusion Shaped torx nut.

[0023] The connecting tool includes a connecting sleeve 100 that can cooperate with the outer peripheral surface of the nut and the head of the bolt, and may further include a connecting handle and / or handle connected with the connecting sleeve, and the connecting handle may have a quick-change joint.

[0024] The connection configuration of the connection sleeve is based on one of the specifications of the nut and the bolt head of the twelve-tooth profile, and has correspondin...

Abstract

The invention provides a disassembling and assembling tool for nuts and bolts. The disassembling and assembling tool comprises a connecting sleeve capable of being matched with the peripheral face of the nuts and bolt heads. According to the connecting structure, the twelve-tooth-shaped nut and the bolt head of one specification are used as an adaptation foundation, and twelve corresponding connecting grooves are formed. The width of the connecting grooves corresponds to the width of the middle tooth of the selected specification. According to the depth of the connecting grooves, the distance between the bottoms of the two connecting grooves with the opposite front faces is larger than the length between the diagonal peaks of the bolt head and the nut in the square shape and larger than the length between the diagonal peaks of the bolt head and the nut in the hexagonal shape, wherein the nut and the bolt head are of the same specification. The disassembling tool is applicable to the nuts and the bolt heads in five shapes of the same specification and universal to the five shapes of the English system and the metric system, an operator can conveniently use the disassembling and assembling tool, and the tool configuration cost and carrying burdens are lowered.

Description

technical field [0001] The invention relates to a disassembly and assembly tool for a nut and a bolt. Background technique [0002] In the field of fasteners, nuts and bolt heads have various styles. In addition to the common hexagon, there are also various special shapes, such as plum, tooth, square, etc. Each shape, in some There are also inch and metric dimensions. The general multi-function connecting tool adopts a double-head structure, that is, one end is adapted to the nut and bolt head of the first shape, and the other end is adapted to the nut and bolt head of the second shape. In this way, the connecting tool is still only suitable for two shapes, and is bulky, heavy, and expensive. When the user uses it, once the third shape of the nut and bolt head appears, the connecting tool still needs to be replaced. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a disassembly and assembly tool for a nut and a ...
