Sign does not have technical inspiration yet.
Invention content
The purpose of the present invention is to provide adjustable wrench, and reasonable design is simple in structure, and easy to manufacture is time saving and energy saving, lead to
That crosses worm screw moves up and down the quick adjusting for realizing amount of opening, and easy to use, work efficiency is high.
In order to achieve the above objectives, present invention employs following technical solution, adjustable wrench, including pull body, pull mouth, snail
Bar, the body head of pulling are equipped with lateral circular hole, and the mouth of pulling is interspersed in by themselves bottom circular shaft rack in lateral circular hole, described
It pulls body head and also opens up worm screw accommodation space, worm screw is meshed with a mouthful circular shaft rack of pulling for top, in the worm screw accommodation space
It is additionally provided with worm screw arrangement of clutch, the worm screw arrangement of clutch includes spring, left steel ball, right steel ball, and the spring is installed on snail
In the central shaft hole that bar opens up, spring left end withstands left steel ball, and spring right end withstands right steel ball, in the left inside wall of worm screw accommodation space
Upper semisection and the right inner wall upper semisection of worm screw accommodation space open up corresponding arc elongated slot simultaneously, and the left steel ball and right steel ball exist
It is close to corresponding arc elongated slot inner wall under the active force of spring.
When the left steel ball and right steel ball are slided or rolled in corresponding arc elongated slot, no matter slips or to be rolled into arc long
Any position in slot, left steel ball and right steel ball all not exclusively deviate from the central shaft hole of worm screw.
Spiral shell shape tooth is opened up on the worm screw, spiral shell shape tooth one side is vertical plane, and another side is inclined-plane, while pulling mouth rack
Being also adapted to property open up one side be vertical plane, another side be inclined-plane flute profile, the vertical plane of spiral shell shape tooth and pull mouth rack hang down
It faces directly and matches, the inclined-plane of spiral shell shape tooth is matched with the inclined-plane for pulling mouth rack, wherein mouth opening is pulled in the guarantee of matched vertical plane
After limit, pull the inclined-plane of mouth rack side component generated to the inclined-plane of spiral shell shape tooth and push, screw rod is forced to move down, that is, when pulling mouth and opening,
It pushes directly on and pulls metastomium, worm screw moves down under the action of the component of side, pulls the existing quick-make as unit of tooth pitch of cause for gossip.
The present invention has the advantages that compared with prior art：
Worm screw is pulled down, steel ball detaches along elongated slot arc inner wall slide downward, spring-compressed, worm screw with mouth is pulled, and pulling mouth can be with
Free-open-close realizes the quick adjusting of amount of opening.After release, steel ball slides up along elongated slot arc inner wall under the force of a spring
It is dynamic, it worm screw and pulls mouth rack and engages again, restore normal adjustable wrench function.It pulls to push directly on when mouth opens and pulls metastomium,
Worm screw moves down under the action of the component of side, pulls mouth and quick-make as unit of tooth pitch may be implemented.Reasonable design of the present invention, knot
Structure is simple, easy to manufacture, time saving and energy saving, easy to use by the quick adjusting for moving up and down realization amount of opening of worm screw, work
It is efficient.
