Abstract
The utility model relates to a movable wrench which comprises a strip-shaped body, a movable jaw clamp, a driving wheel group, a pushing device and a positioning device, wherein the movable jaw clamp is vertically arranged at one end of the body. The utility model is characterized in that the driving wheel group comprises a first gear engaged with the movable jaw clamp and a second gear arranged between the first gear and the movable jaw clamp so as to drive the pushing device, and the driving wheel group drives the movable jaw clamp to make straight-line movement so as to achieve the purpose of quick adjustment. The positioning device makes the pushing device fixedly locked on a proper position, so the movable wrench with stable positioning and quick adjustment is formed.
Description
Technical field
The utility model is about a kind of monkey wrench, and it is involved in the technical field of hand-held tool, and outstanding pointer is improved the structural design that monkey wrench control activity jaw moves, and reaches quick, the stable purpose of operation.
Background technology
In the existing monkey wrench, a kind of form is arranged is a body is coated with a movable jaw that is the crutch shape in a side, the end face of side correspondence is provided with and fixedly stings piece in addition, body is provided with a breach with ccontaining one nut that is sheathed on the movable jaw in a side of movable relatively jaw, one end of this nut and movable jaw is screwed, therefore when the rotary nut of original place, meeting driving activity jaw advances or retreats, make its relative fixed sting piece and form different distance, use for different working substance clampings with the spacing of fixedly stinging piece to adjust movable jaw.
Because the mode of control activity jaw is directly joined with movable jaw by nut, contact area is little, therefore make the activity jaw form lifting when direct rotating screw cap, long because of the rotate path of circulating type, and make movable jaw be clipped in axial moving slowly, not easy rapidly when making us feeling to adjust; And, lack the device that the location is arranged between nut and movable jaw, cause movable jaw to accompany loosening situation unavoidably, make on the application of force of holder crop that because movable jaw pine rolling and walking, it is stable to be difficult to clamping.
Summary of the invention
Therefore, this creator sets about research and development, and in line with professional experiences and gains in depth of comprehension for many years, concentrated test is weeded out the old and bring forth the new, and then proposes the utility model, in the hope of improving the scarce fraud of traditional activity spanner.
Main purpose of the present utility model is for providing a kind of monkey wrench; the design of monkey wrench adjustment activity jaw is carried out with the axial straight line way of propelling; have rapidly easy characteristic, and have both the polarization that fixes, guarantee that movable jaw can not rock easily and influences the reliability of clamping.
For achieving the above object, its structure of monkey wrench of the present utility model includes:
One body, it is the flat strip with two ends, the one end is comparatively long and narrow as a lever, another opposite end is for being wide bellend than lever, the bellend end face is provided with one and fixedly stings piece, should fixedly sting piece have an arc-shaped head and a neck, the arc-shaped head inner edge be formed with one with the vertical identical occlusal surface of body, be formed with a storage tank in the neck; Body interior vertically forms a chute, is formed with two gear grooveds that are interconnected in the bellend, in order to be communicated with the storage tank of fixedly stinging piece with chute respectively;
One is arranged in the movable jaw of fixedly stinging the piece storage tank with movable manner, have a long and straight section and a bending section, long and straight section is placed in the storage tank, and it is provided with denture near body one side, bending section stretch out fixedly sting piece and form one can with fixedly sting the occlusal surface that piece meshes;
One rotary way is hubbed at the driving wheels in the body, and it includes one first gear and one second gear, and two gear interlocks join, and wherein second gear is meshed with the denture of movable jaw;
One can drive the drive unit of driving wheel, includes a push button that can be placed on the interior tooth-arranging strip of chute and formation and the tooth-arranging strip, and this tooth-arranging strip is meshed with first gear; With
One is installed in the positioner of tooth-arranging strip end.
By the conduction that drives wheels, when promoting tooth-arranging strip with drive driving wheels, can further can allow movable jaw be subjected to axial promotion, move along direction perpendicular to body, reach the effect that fast moving is adjusted, and the steadiness of the installing of positioner more can increase monkey wrench and seize the work object on both sides by the arms the time.
Through last explanation, design of the present utility model can improve the shortcoming of traditional activity spanner fully:
1. the utility model sees through tooth-arranging strip and the design that drives wheels, and movable jaw can be promoted by axial straight line, and just the position of the jaw of adjustment activity promptly is convenient rapidly.
2. the utility model is controlled tooth-arranging strip slidably state and on-position via positioner, movable jaw is determined in on-position, cooperate the concavo-convex engagement limits of chute and tooth-arranging strip to locate, it is better to allow the activity of movable jaw sting the effect of piece and occlusal surface holder crop.
