Abstract
An adjustable wrench comprises a body, a handle arranged at one end of the body, an adjustable clamp arranged at other end of the body and an adjusting worm wheel pivoted on the body. The adjustable clamp comprises a fixed jaw, a sliding chute and a movable jaw arranged in the sliding chute, threads are arranged on the movable jaw, and the movable jaw is engaged with the adjusting worm wheel; and a groove or a notch is arranged on one side of the adjusting worm wheel, and a gap is arranged between the groove or the notch and the movable jaw. The adjusting worm wheel is engaged with the movable jaw through the threads, and the movable jaw can be moved by rotating the adjusting worm wheel, so as to change the distance between the movable jaw and the fixed jaw. One side of the groove or the notch arranged on the adjusting worm wheel can be rotated to correspond to threaded end of the movable jaw, then the adjusting worm wheel and the movable jaw are kept a certain gap and can not be engaged, so that the movable jaw can be moved by hands along the sliding chute to achieve the purpose of rapidly adjusting the opening of the movable jaw.
Description
Technical field
The utility model relates to hand tools, especially a kind of monkey wrench.
Background technology
Traditional monkey wrench comprises body, is located at the handle of body one end, is located at the live splint of the body other end and is articulated in the adjustment worm gear on the body; Said live splint comprises fixed jaw, chute and is located at the movable jaw in the chute; Movable jaw is provided with screw thread; Movable jaw and the engagement of said adjustment worm gear through rotation adjustment worm gear movable jaw is moved, thereby the distance between change fixed jaw and the movable jaw are to adapt to the workpiece demand of different size.In the middle of the practical application, the sized of workpiece is to have nothing in common with each other, and need the live splint of monkey wrench be adjusted to maximum sometimes; Then need adjust to minimum sometimes; This just needs to adjust worm gear and rotates a lot of Zhou Caineng realizations, has dragged slowly work rhythm beyond doubt, causes inefficiency.
Summary of the invention
The utility model technical problem to be solved provides a kind of monkey wrench, and the size that can change live splint folder mouth fast is to adapt to the workpiece demand of different size, and is easy to use, helps to increase work efficiency.
For solving the problems of the technologies described above, the technical scheme of the utility model is: a kind of monkey wrench, comprise body, be located at said body one end handle, be located at the live splint of the said body other end and be articulated in the adjustment worm gear on the said body; Said live splint comprises fixed jaw, chute and is located at the movable jaw in the said chute that said movable jaw is provided with screw thread, said movable jaw and the engagement of said adjustment worm gear; Said adjustment worm gear one side is provided with groove or otch, is provided with the gap between said groove or incision and the said movable jaw.Adjustment worm gear and movable jaw can make movable jaw move through rotation adjustment worm gear, thereby change the distance between movable jaw and the fixed jaw through screw-threaded engagement.In the middle of the practical application; Need the folder mouth of live splint be adjusted to maximum or minimum sometimes; Need walking for fear of movable jaw, the stroke of length just can achieve the goal and drag and work slowly; One sideway swivel that can the adjustment worm gear be provided with groove or otch is adjusted between worm gear and the movable jaw and can not be meshed the i.e. not constraint of regulated worm gear of movable jaw apart from certain interval to be provided with screw thread one end corresponding with movable jaw at this moment; Therefore can directly move movable jaw along chute, to reach the purpose of rapid adjustment live splint folder mouth with hand; After movable jaw moved on to Position Approximate fast, the principle adjustment movable jaw that utilizes adjustment worm gear and movable jaw engagement again was to suitable position.
The beneficial effect that the utility model is compared with prior art brought is:
In the middle of the practical application; Need the folder mouth of live splint be adjusted to maximum or minimum sometimes; Need walking for fear of movable jaw, the stroke of length just can achieve the goal and drag and work slowly; One sideway swivel that can the adjustment worm gear be provided with groove or otch is adjusted between worm gear and the movable jaw and can not be meshed the i.e. not constraint of regulated worm gear of movable jaw apart from certain interval to be provided with screw thread one end corresponding with movable jaw at this moment; Therefore can directly move movable jaw along chute, to reach the purpose of rapid adjustment live splint folder mouth with hand; After movable jaw moved on to Position Approximate fast, the principle adjustment movable jaw that utilizes adjustment worm gear and movable jaw engagement again was to suitable position.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Be described further below in conjunction with Figure of description contrast the utility model.
As shown in Figure 1, a kind of monkey wrench, comprise body 2, be located at said body 2 one ends handle 1, be located at the live splint of said body 2 other ends and be articulated in the adjustment worm gear 3 on the said body 2; Said live splint comprises fixed jaw 5, chute and is located at the movable jaw 6 in the said chute that said movable jaw 6 is provided with screw thread, said movable jaw 6 and said adjustment worm gear 3 engagements; Said adjustment worm gear 3 one sides are provided with groove 4, are provided with the gap between said groove 4 places and the said movable jaw 6.Adjustment worm gear 3 passes through screw-threaded engagement with movable jaw 6, through rotation adjustment worm gear 3 movable jaw 6 is moved, thereby change the distance between movable jaw 6 and the fixed jaw 5.In the middle of the practical application; Need the folder mouth of live splint be adjusted to maximum or minimum sometimes; Needing to walk for fear of movable jaw 6, the stroke of length just can achieve the goal and drag and work slowly; One sideway swivel that can adjustment worm gear 3 be provided with groove 4 is adjusted between worm gear 3 and the movable jaw 6 and can not be meshed the i.e. not constraint of regulated worm gear 3 of movable jaw 6 apart from certain interval to be provided with screw thread one end corresponding with movable jaw 6 at this moment; Therefore can directly move movable jaw 6 along chute, to reach the purpose of rapid adjustment live splint folder mouth with hand; After movable jaw 6 moved on to Position Approximate fast, the principle adjustment movable jaw 6 that utilizes adjustment worm gear 3 and movable jaw 6 engagements again was to suitable position.
It is pointed out that on adjustment worm gear 3, otch can be set also replaces groove 4, as long as between the incision and movable jaw 6 ends of thread gap of existence is arranged.
