Abstract
The invention relates to a rapid-adjustable antiskid monkey wrench. Wherein an adjustable wrench head is connected with an adjustable wrench body by concavo-convex connection; a keyway is formed in the adjustable wrench head; an eccentric key and a pressure spring are embedded in the keyway; and a button is disposed outside the eccentric key. A jaw can be opened when the button is dialed to the opposite direction of the spring tension, and the adjustable wrench head is closed to the direction of a fixed wrench head when the adjustable wrench head is pushed to the direction of the fixed wrench head. When operating a workpiece, the force applied on both walls of a concave track by a cambered surface of the eccentric key and the top of a boss of the eccentric key is increased along with the force applied on the adjustable wrench head for causing self locking; and in the self locking state, it is impossible for the adjustable wrench head to depart from the fixed wrench head. The present invention has the advantages of simple and reasonable structure and high opening and closing speed; fundamentally solves the problem of slipping, and improves operation safety.
Description
Technical field
The invention belongs to a kind of manual hardware ﹠ tools, relate in particular to a kind of adjustable wrench.
Background technology
Adjustable wrench is one of a kind of instrument that the most generally uses in the hand-operated tools, and the operator can regulate use within the specific limits according to the nut of different specification size.The most modes that adopt tooth bar to cooperate of existing adjustable wrench with worm gear, need screw worm gear frequently to regulate the jaw folding with the adjustable wrench of this fit system manufacturing when the bolt of twisting different size or the nut, governing speed is slow, skid easily, operate dangerously, and be bound to be subjected in various degree damage by the bolt after the twisting or nut angle.
Summary of the invention
In order to overcome the deficiency of existing adjustable wrench, the invention provides a kind of anti-skidding adjustable wrench, this adjustable wrench has not only kept all functions of existing adjustable wrench, and can carry out opening apace and regulate, loose skidding can not take place back in movable jaw when switching bolt or nut, clamping is firm, can not damage bolt or nut, and handling safety is reliable.
For achieving the above object, the present invention has adopted following technical scheme: movable jaw adopts concavo-convex mode to be connected cooperation with pulling between the body, and movable jaw can move freely at the concave groove that is positioned at wrench body; Be provided with keyway in movable jaw, keyway is embedded in eccentric key and a stage clip, and the cooperation between the three makes movable jaw have eccentric auto-lock function when the switching nut.Its structural feature is: keyway is open, is fan-shaped, top semicircular in shape face; Eccentric key has an end semicircular in shape face, curved an of end corresponding with it, the semicircle face of eccentric key is identical with the radius of the semicircle face of keyway, make an end of eccentric key cambered surface can be in keyway be that move at the center with the center of circle of the semicircle face of keyway, eccentric key cambered surface one end rises between its semicircle face a boss, eccentric key boss and the corresponding one side of eccentric key cambered surface are convex surface, and the ultimate range between eccentric key cambered surface and this convex surface summit is greater than the distance between non-conterminous two walls of concave groove; Be provided with button being the cambered surface one end outside near eccentric key, the open place of keyway has a breach to be mated simultaneously, moves around in keyway and provides or the function of the eccentric self-locking of releasing activity binding clip thereby can control eccentric key by button.
The anti-skidding adjustable wrench of the present invention is compared with existing up-to-date adjustable wrench technology, have simple in structure, processing is convenient, it is accurate rapidly to regulate folding, fundamentally solved the skidding of adjustable wrench, increased the service life of nut or bolt, improved the safety of operation, adjustable wrench can both be acted on applied force above the workpiece in maximum opening and minimum aperture scope efficiently.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the movable jaw structural representation.
Among the figure: (1) pulls body; (2) fixing spanner; (3) movable jaw; (4) handle; (5) eccentric key; (6) stage clip; (7) keyway; (8) concave groove; (9) the semicircle face of keyway; (10) eccentric key boss; (11) eccentric key semicircular in shape face; (12) eccentric key cambered surface; (13) eccentric key boss top; (14) eccentric key spring hole; (15) be positioned at the spring eye of movable jaw boss; (16) movable jaw boss; (17) concave groove upper wall; (18) concave groove lower wall; (19) be positioned at button above the eccentric key; (20) breach.
The specific embodiment:
The invention will be further described below in conjunction with accompanying drawing, but the present invention is not limited only to this embodiment:
As shown in Figure 1 and Figure 2, the present invention is by (1) wrench body; (2) fixing spanner; (3) movable jaw; (4) handle; (5) eccentric key; (6) stage clip and (19) are positioned at the button composition above the eccentric key.Stage clip (6) one ends are injected the spring eye (15) that is arranged in movable jaw boss (16), the other end of stage clip (6) is inserted in the eccentric key spring hole (14), pushing eccentric key (5) makes stage clip (6) contraction that eccentric key (5) is embedded in the keyway (7), movable jaw (3) and the eccentric key (5) and the stage clip (6) that embed in its keyway (7) are pushed concave groove (8) from the opening in concave groove (8) left side in the lump, being pushed into fixedly, spanner (2) contacts with movable jaw (3), because the maximum distance between eccentric key boss top (13) and the eccentric key cambered surface (12) is greater than the distance between concave groove (8) upper wall (17) and the lower wall (18), as need open once more jaw then must be when pushing the button (19) that is positioned at above the eccentric key with movable jaw (3) to stirring away from the fixing direction of spanner (2), because under the situation that does not have external force to exert pressure, because the tension force of stage clip makes eccentric key cambered surface (12) and eccentric key boss top (13) be against respectively on the upper wall (17) and lower wall (18) of concave groove (8), movable jaw this moment (3) is with respect to fixedly forming self-locking between the spanner (2), movable jaw (3) is to away from fixedly spanner (2) direction is stressed big more, the active force that eccentric key cambered surface (12) and eccentric key boss top (13) act on concave groove (8) upper wall (17) and lower wall (18) is strong more, self-locking strength is big more, and movable jaw can not take place away from the fixing phenomenon of spanner; The back side that is positioned at eccentric key boss (10) is provided with a button (19), adapt therewith, be positioned at the movable jaw bottom one breach (20) is arranged, when when stirring this button with stage clip tension force rightabout, make vertical range between eccentric key boss top (13) and the eccentric key cambered surface less than the vertical range between concave groove (8) upper wall (17) and the lower wall (18), this moment, movable jaw can be to moving away from fixing spanner (2) direction, when when the regular jaw direction promotes movable jaw (3), owing to be along the opposite direction application of force of stage clip tension force, be equal to and stir button (19), eccentric key (5) can't be realized the function of its eccentric self-locking, movable jaw this moment (3) is easy to be pushed to fixedly spanner (2) along concave groove (8), until ending when contacting with fixing spanner (2).
