Abstract

The utility model belongs to a manual tool, particularly relates to an adjustable wrench capable of being adjusted quickly, and provides a quick adjustable wrench. The adjustable wrench not only keeps all functions of a common adjustable wrench, but also has the function of quickly opening and closing a clamping surface. When a workpiece is clamped, a user holds a wrench handle with a hand, simultaneously pinches a worm with a thumb and an index finger, and drags the worm downwards, so that a movable wrench head of the adjustable wrench can quickly move back and forth on a fixed wrench head. When the workpiece is clamped, the movable wrench head only needs to be pushed towards the fixed wrench head, the workpiece can be quickly locked by means of fine adjustment of the worm, and accordingly work efficiency is greatly improved. In addition, the quick adjustable wrench is simple in structure, convenient in processing and low in manufacturing cost, and is the best substitute product for the common adjustable wrench.

Description

Adjustable wrench

Technical field

The utility model belongs to a kind of hand-operated tools, relates in particular to a kind of adjustable wrench that has the quick adjustment function.

Background technology

Adjustable wrench is one of instrument that the most generally uses in the hand-operated tools; The advantage of common adjustable wrench is the hexagon workpiece of the plurality of specifications of switching simultaneously size; Its inferior position is when at the very big workpiece of rotation specification difference, needs the long period rotary worm, and operating efficiency is lower.

Summary of the invention

In order to overcome the deficiency of common adjustable wrench, the utility model provides adjustable wrench, and this adjustable wrench has not only kept all functions of common adjustable wrench; And the function that can make the rapid folding of clamping face is provided, during the clamping workpiece, hold trigger piece and pinch simultaneously under the worm screw with thumb and forefinger and drag; Movable jaw just can be rapidly to sliding away from fixing spanner direction, unclamp worm screw and touch movable jaw and can make it to fixedly the spanner direction is mobile rapidly, when with after workpiece contacts; Rotary worm just can pin workpiece rapidly a little, thereby has improved work efficiency greatly, the utility model simple in structure; Easy to process; Low cost of manufacture is particularly suitable for producing in enormous quantities, is the best substitute products of common adjustable wrench.

Be to realize above-mentioned purpose, the utility model has adopted following technical scheme: adjustable wrench, and said adjustable wrench is formed by pulling body, movable jaw, worm screw, bearing pin, spring, supporting pin, of bonding voussoir, spacer pin; The front end of pulling body has fixedly spanner, and there is handle the rear end of pulling body, fixedly on the spanner clamping face is arranged; Fixedly below the spanner groove, said groove internal upper part being arranged is two faces that are parallel to each other, and the groove bottom is arc surface; Mid portion at said arc surface has gap to communicate with a rectangular through-hole downwards, and movable jaw is made up of three parts in upper, middle and lower, and clamping face is arranged at top; The thickness at middle part is less than the distance that is parallel to each other in the said fixedly spanner groove between two faces, and the bottom bilateral symmetry is arc surface, and the ultimate range between its cambered surface is less than the diameter of said fixedly spanner bottom portion of groove arc surface; Said movable jaw lower tip is provided with teeth, and the helical tooth of these teeth and worm screw is meshing with each other, and it is characterized in that; Be positioned at said fixedly spanner groove below and be provided with the of bonding hole, the of bonding hole is run through said rectangular through-hole and is extended to the below that is close to said fixedly spanner clamping face from the surface of pulling away from fixing spanner clamping face, forms an of bonding through hole and an of bonding blind hole; Lay respectively at the both sides of said rectangular through-hole, the center line in of bonding hole is vertical with said fixedly spanner clamping face, and two spring eyes run through said groove bottom; Extend to the another side of of bonding through hole and of bonding blind hole respectively, spring one end is seen through the groove bottom insert respectively in the spring eye, the thinner end of two supporting pins is seen through the groove bottom equally insert respectively in the centre bore of spring; Be placed on worm screw in the middle of the said rectangular through-hole; From pulling external side bearing pin one end is inserted the of bonding through hole, press down the supporting pin top in the said of bonding through hole simultaneously, bearing pin is positioned on the arc-shaped concave on said supporting pin top; Pass the centre bore of worm screw; Press down the supporting pin top in the of bonding blind hole simultaneously, be positioned at until said bearing pin on the arc-shaped concave on said supporting pin top and and contact, afterwards the of bonding voussoir is embedded in the said of bonding blind hole from pulling external side with of bonding blind hole bottom surface; Stop bearing pin to come off from pulling body; Press down worm screw along the spring tension rightabout, the clamping face of movable jaw be inserted in the groove of said fixedly spanner in the face of the clamping face of fixing spanner and with it, be positioned at said movable jaw in the middle part of a side be provided with groove; Match with it; Being provided with limiting through hole away from fixing groove one side of spanner clamping face, spacer pin is fixed in the said limiting through hole, stop movable jaw along away from fixedly spanner clamping face direction slippage.

Said worm spiral tooth teeth face extension line intersects and is acute angle, and the teeth top is cambered surface and annular knurl is handled.

The length of said spring is less than the spring eye degree of depth away from said groove one side.

Said supporting pin is cylindrical, and the curved concave surface of an end.

Hold spanner, pinch worm screw simultaneously along moving away from fixing spanner groove direction with thumb and forefinger, spring is compressed at this moment; Make the helical tooth of said worm screw break away from fully and the engagement that is positioned at movable jaw lower tip teeth, this moment, movable jaw can be free to slide along said fixedly spanner groove, unclamped said worm screw; Because the angle design of helical tooth is reasonable, under the tension force effect of spring, said helical tooth can automatically and be positioned at said movable jaw lower tip teeth and be meshing with each other; When said movable jaw during away from said fixedly spanner clamping face; To touching spanner near fixing spanner clamping face direction, this moment, spring was compressed descendingly automatically, need not under the situation of rotary worm with thumb; Said movable jaw just can be to said fixedly spanner clamping face direction fast moving; When needing rotational workpieces, when said fixedly spanner clamping face and said movable jaw clamping face with after workpiece contacts, with thumb and forefinger a little rotary worm finely tune; Described two clamping faces just can be locked surface of the work rapidly, thereby reach the purpose of rapid adjusting clamping face folding.
