Description
Technical Field
The utility model relates to the technical field of manual hardware tools, in particular to a wrench with an adjustable rotation angle.
Background
In the process of vehicle maintenance and mechanical maintenance, a plurality of loading and unloading operation spaces are narrow, the rotation angle can be insufficient by 60 degrees when the nut is screwed by the conventional spanner, the nut cannot be screwed by the loading and unloading tool again, at the moment, the nut can be continuously screwed by the conventional spanner only after being rotated by 60 degrees by means of other non-spanner tools, and the nut is often worn or damaged by other non-spanner tools.
Disclosure of Invention
The utility model aims to make up the defects of the prior art, and discloses a wrench with an adjustable rotation angle, namely when the nut is screwed by less than 60 degrees, the angle of a handle is adjusted by matching the teeth at the rear part of the wrench head with the teeth of the reversing switch, so that the handle can continuously screw the nut by more than 60 degrees, and the rapid repeated screwing operation is realized.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
The utility model provides an adjustable spanner of turning angle, includes spanner head, handle, steering switch, round pin axle A, elastic element, steel ball, round pin axle B, the handle head is equipped with the through open slot, and the open slot bottom is equipped with the counter bore, and both sides face is equipped with two round pin axle holes C, D, spanner head afterbody is equipped with the round pin axle hole, and the outer fringe is equipped with the tooth. The steering switch is triangular, a pin shaft hole is formed in the top angle position, teeth are arranged in the two bottom angle positions, the spanner head is positioned in the handle open slot and fixed at the pin shaft hole C position through a pin shaft A, the steering switch is positioned in the open slot and fixed at the pin shaft hole D position through a pin shaft B; the elastic element is positioned in a counter bore at the bottom of the handle opening groove, the steel ball is positioned above the elastic element and is contacted with the side surface of the bottom of the steering switch, the steel ball is pushed upwards by the thrust of the elastic element to play a positioning locking function on the side surface of the top angle of the steering switch, when the steering switch is in right inclination, the tooth at the left upper side of the steering switch is meshed with the tooth at the tail part of the spanner head, at the moment, the spanner head can adjust the opening angle clockwise, meanwhile, the tail part of the handle can apply force clockwise to screw a nut or a bolt, the resistance of the elastic element is manually overcome to enable the steering switch to rotate leftwards, so that the tooth at the right upper side of the steering switch is meshed with the tooth at the tail part of the spanner head, at the moment, the spanner head can adjust the opening angle anticlockwise, and at the same time, the tail part of the handle can apply force anticlockwise to screw the nut or the bolt.
