Embodiment Construction

[0022] Refer to attached picture. The connecting tool for nuts and bolts provided by the present invention can be applied to bolt heads 1 with twelve tooth shapes, bolt heads 2 with hexagonal shapes, bolt heads 3 with square shapes, torx bolt heads 4 with twelve protruding shapes, The torx bolt head 5 with six protruding shapes can also be applied to nuts with twelve teeth, hexagonal nuts, square nuts, twelve protruding torx nuts, hexagonal protruding Shaped torx nut.

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

[0024] The connecting configuration of the connecting sleeve is based on one of the twelve-tooth nut and bolt head specifications, and has twelve corresponding connecting grooves 101; the specification is the clo...

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 dismounting tool for nuts and bolts. Background technique [0002] For the field of fasteners, there are many styles of nuts and bolt heads. In addition to the common hexagonal shape, there are also various special shapes, such as plum blossom type, tooth shape, square shape, etc. Each shape, in some Sizes are also available in imperial and metric. The general multi-functional connection tool adopts a double-head structure, that is, one end is adapted to the first shape of the nut and the bolt head, and the other end is adapted to the second shape of the nut and the bolt head. In this way, the connecting tool is still only applicable to two shapes, and the volume and weight are large, and the cost is also high. When the user uses it, once the third shape of the nut and bolt head appears, the connection tool still needs to be replaced. Contents of the invention [0003] The technical problem to be solved by the present in...
