CN2543670Y - High-efficient adjustable wrench - Google Patents

Abstract

The utility model relates to a high-efficient adjustable wrench which is an improved moveable wrench and can be quickly inserted into the square keys and bits. The opening distance of the wrench opening is guaranteed to be permanent, the force used for wrenching the square body is great, and no torsion is transmitted to the square body when relying on the square body during the return, so that the aim of high efficient operation through the to-and-fro swing in the wrenching of the square body is achieved. The wrench of the utility model is large in the movement area, good in rigidity, strong in the practicality and flexible in operation, with the combination of the advantages of the moveable wrench and the ratchet wrench. Besides, the wrench of the utility model is low in production cost, with the selling price equal to the price of the moveable wrench on the market, so that the production is convenient and the social effect is good. The wrench of the utility mode is convenient and practical when used as the spare instrument in the mechanical part assembly, the repair industry and at homes, and thus is an ideal hardware instrument.

Description

Efficient monkey wrench

The utility model relates to a kind of improved monkey wrench, the dismounting of twisting rapidly and efficiently of its side's of being applicable to body or nut screw (hexahedron).

Known monkey wrench is mainly formed by fixedly pulling body, Flexible spanner body, worm screw and screw mandrel device.Because the transmission device gap is big.Pull the tight power of stutter little, easily loosening, rigidity is not enough.And its mouthful working face of pulling is contour (or isometric), during operation, must will pull mouthful each one group of parallel opposite side aiming at hexahedron and could insert or put into and pull mouth, the operation of tightening or unclamping.Its weak point is can not be quick, makes exactly to pull mouth and enter the operating position.

The purpose of this utility model provides a kind of improved monkey wrench, and it can be from any direction side's of insertion body twisting fast, during revolution, must not withdraw from and pull mouth, just can rotate against square body, particularly hexahedron, and do not transmit moment of torsion, thereby reach the purpose that reciprocally swinging twisting side height is imitated operation.

Technical solution of the present utility model is: it is formed by fixedly pulling body, Flexible spanner body, worm screw, screw mandrel, worm screw hold-down screw, shell fragment and shell fragment hold-down screw.Its special character is: will fixedly pull the face height of pulling mouth of body and Flexible spanner body, and make the both sides working face that both height do not wait, the mouth of pulling of its Flexible spanner body is higher than the mouth of pulling of fixedly pulling body, and is parallel to each other; Press from both sides an angle at mouthful working face root of pulling of fixedly pulling body, make one and support resistance face, the two sides forms one " V " word, connects a slick and sly excessive cambered surface at mouthful working face end of pulling of Flexible spanner body, and being connected to the hypomere working face, this working face is parallel to each other with the hypomere working face of pulling mouth of fixedly pulling body.

Make a screwed hole on the tooth bar front end face of the utility model Flexible spanner body, so that a last shell fragment hold-down screw, this screw is fixed a shell fragment, and shell fragment is made " Z " word, be placed on the reinforcement of Flexible spanner body, when pulling mouthful little hexahedron of twisting, can play and help the effect of moving back hexahedron, so that make when pulling mouthful twisting revolution, automatically withdraw from the hexahedron stress surface, rotate against hexahedron, and do not transmit moment of torsion, thereby reach the purpose of better reciprocally swinging twisting hexahedron efficient operation.

The utility model is fixedly pulled on the bottom surface, below of body dress worm screw and is made a screwed hole, so that a last worm screw hold-down screw, this screw fixedly worm screw is motionless, thereby it is easily loosening to reach control Flexible spanner body, guarantees to pull the constant purpose of distance between the mouth.

Structure of the present utility model is as follows by following examples and description of drawings thereof:

Fig. 1 has described an embodiment of the present utility model.

Fig. 1 is a structural representation of the present utility model.It is improved a kind of monkey wrench on the basis of traditional activity spanner.Pull the working face of mouth for the Flexible spanner body as figure: AB; Body slip of the BC side of being and the cambered surface (comprising that pulling mouthful working face also has against the possibility of square body slip) that reciprocatingly slides against square body; MN is for fixedly pulling body pulls a mouthful working face; NO is that style supports resistance face, and also the side's of being body is against the face that reciprocatingly slides; CD and OP are pull mouthful (working face is changeable) of former monkey wrench; KSTU is a square hole; TV is the square hole bottom surface; L is the worm screw hold-down screw; V is a worm screw; W is a screw mandrel; HEFG is a tooth bar; EF is the tooth bar front end face; K is the shell fragment hold-down screw; Z is " Z " word shell fragment; DE is a reinforcement; IQ is a slide rail; X is a hexahedron; Y is a handle.

The utility model has the advantages that: it pull a mouthful opening broad, easily quick insertion side body, and pulling mouthful extended distance can guarantee constant, body power that is critical in twisting side's is big, during revolution, do not transmit moment of torsion against square body, can reach the purpose that reciprocally swinging twisting side height is imitated operation, have the effect of ratchet spanner.

In sum, the utlity model has fast, efficient, scope of activities is wide, and good rigidly is practical, and is flexible to operation.It combines the chief of fork spanner, monkey wrench and ratchet spanner.In addition, also have low cost of manufacture, similar with commercially available monkey wrench.Be convenient to produce, social effect is good.Be used for machine components assembling, repairing trades, family's cutfit, promptly convenient practical again, be a kind of desirable hardware ﹠ tools.

Claims (4)

1, a kind of by fixedly pulling the monkey wrench that body, Flexible spanner body, worm screw, screw mandrel, worm screw hold-down screw, shell fragment and shell fragment hold-down screw are formed, it is characterized in that Flexible spanner mouth and the face height of fixedly pulling mouth do not wait, a side wherein is higher than opposite side.

2, by the described spanner of claim 1, it is characterized in that pulling a mouthful side and be " V " word bayonet socket working face, opposite side is the excessive circular curve working face of straight line.

3,, it is characterized in that pulling a mouthful bottom and be equipped with and help extracting property element by the described spanner of claim 1.

4,, it is characterized in that in the square hole of spanner dress worm screw the worm screw retaining element being housed by the described spanner of claim 1.
