Description
Technical field
The present invention relates to five metals hand-operated tools field, specifically a kind of adjustable wrench of adjustable handle.
Background technology
Existing adjustable wrench the handle front end by pull body, pull mouth, worm screw, bearing pin, spring form; Pull a mouthful following horizontal worm screw with the finger turn during use,, drive and be located at the tooth bar of pulling mouthful bottom through the turn worm screw; The size of opening of mouth is pulled in control; Clockwise or counterclockwise turn-knob is carried out on the both sides of clamping workpiece nut or bolt opposing parallel, driving handle, can be with the workpiece turn.When running into that workpiece gets rusty or need very energetically rotational workpieces, generally all be to be used in the mode that puts extension pipe on the handle to strengthen the arm of force and carry out turn-knob, troublesome poeration is wasted time and energy like this, also need carry sleeve pipe.
Summary of the invention
The objective of the invention is in order to solve the deficiency of above-mentioned technology, provide a kind of rational in infrastructure, simple, be prone to make, easy to use, the adjustable wrench of ability labour-saving adjustable handle.
The scheme that the present invention taked is: a kind of adjustable wrench of adjustable handle, and comprise and pull body, pull mouth, worm screw, bearing pin, spring, handle, it is characterized in that a side of pulling the body rear portion is provided with two locating slots; Opposite side is provided with step, and one side is provided with locating hole in the front portion of extension bar, and opposite side is provided with the grooved hole; The front portion of extension bar is inserted in and is pulled the body rear portion, in the anterior locating hole of extension bar, is provided with steel ball, and the steel ball bottom embeds and pulls in the locating slot at body rear portion; The outside of extension bar is provided with movable sleeve; Movable sleeve one side is provided with circular hole and spacer pin, and the alignment pin in the circular hole passes in the anterior grooved hole entering of extension bar and pulls on the step at body rear portion, and a side is provided with the inclined-plane in the movable sleeve; On the inclined-plane, be provided with spring; The movable sleeve rear portion is provided with handle on extension bar, movable sleeve drives alignment pin moves forward and backward extension bar, and the inclined-plane is pressed into steel ball and pulls in the body locating slot fixedly extension bar in the movable sleeve.
Because movable sleeve drives alignment pin and can extension bar be moved forward and backward, be actively set on and utilize the inclined-plane that steel ball is pressed under the spring action to pull in the body locating slot fixedly extension bar, through adjustment extension bar change in location change spanner length.The present invention is reasonable in design, and is simple in structure, use, easy to operate, time saving and energy saving.
