Description

Pipe wrench formula multifunctional wrench

The utility model relates to a kind of pipe wrench formula spanner.

Instrument such as monkey wrench or pipe vice is a common tool, and in the medium usually use of our daily life, work, but uses such as common monkey wrench, pipe vice are very inconvenient, often adjust, and are dangerous again, also can damage nut.People update for this reason, disclose a kind of spanner as Chinese patent CN2228824Y, and the shortcoming of this spanner is that 1. the scope of application is little, do not want many for the moment when the size of workpiece and just can finish the work spanner; 2. 3 contact inconvenience of this spanner are used for the workpiece work of other shapes, and the possibility of defective work piece is arranged.

The purpose of this utility model is to provide a kind of spanner with pipe wrench formula.

The utility model is realized in the following manner, the working end of handle is toothed circular arc, straight line, the ratio 0.5～1: 3.5～3 of straight line and circular arc line, clamp on the binding clip toothed working face is arranged, handle is connected by bearing pin with the clamping binding clip makes workpiece be clamped by two working faces, realizes the work purpose.

The utlity model has simple in structure, both sides contacts, the characteristics that the inside and outside can both be used, non-slip during work, the scope of application is big, can adapt to the workpiece of Any shape.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model.

Handle 1 is connected with clamping binding clip 3 by bearing pin 2, the front end of the working face 4 of handle 1 is toothed straight line A, the rear end is toothed circular arc line B, and the ratio of A and B is preferably A: B=0.5～1: 3.5～3, and the working face that clamps binding clip 3 is toothed straight line 5, workpiece 6 is sandwiched between 4 and 5, because 2 contacts can clamp the workpiece of Any shape, and do not lose workpiece, spanner is non-slip, angle α is 90 °＜α＜180 °, and angle β is 90 °＜β＜180 °.When workpiece hour, act on the A section, so the scope of application is big, the big I of workpiece is between 19～70mm.

The utility model is the substitute products of products such as pipe vice, monkey wrench, and good prospects for application is arranged.

Claims (2)

1, a kind of pipe wrench formula spanner, it by handle (1), bearing pin (2), clamp binding clip (3) and wait and form, it is characterized in that acting surface (4) is made up of straight line (A) and circular arc line (B), (A): (B) be preferably 0.5～1: 3.5～3.

2, a kind of pipe wrench formula spanner according to claim 1 is characterized in that clamping angle (α), (β) on the binding clip (3) and is 90 °＜α＜180 °, 90 °＜β＜180 °.
