Description

High-efficiency monkey wrench with swing forceps edge

The utility model relates to hand-operated tools, particularly belongs to a kind of opening adjustable wrench with ratchet spanner function.

As everyone knows, spanner is trip bolt, a nut in industry and the daily life, widely used instrument.Now, the spanner that generally uses of people mainly contains open-end wrench and ratchet wrench.Although multifarious miscellaneous spanner is arranged now, all be to develop from above-mentioned two class spanner structures.Ratchet wrench is to adopt closed engage sleeves part, if narrow space or cable pass nut, so just can't use closed sleeve barrel tool, if use open-end wrench, the particularly twisting of crawl space nut, spanner withdraws down first power after will rotating to an angle, and uses very inconvenient, inefficiency.

In view of the deficiencies in the prior art, the purpose of this utility model provides a kind of have ratchet spanner and two kinds of functions of open-end wrench, and is simple in structure, easy to use, increases work efficiency the efficient adjustable wrench of band swing jaw.

The utility model is to realize like this.This spanner comprises is with handle, fine setting screw rod, the Flexible spanner mouth of fixedly pulling mouth to form, and its structural feature is: establish the jaw that can swing by pin on the Flexible spanner mouth, be provided with epicycloidal concave surface on the mouth fixedly pulling of handle.

Below by accompanying drawing the utility model is further specified.

Find out with reference to Fig. 1, Fig. 3, go up by bearing pin (7) at handle (6) and be provided with fine setting screw rod (8), tooth bar on the Flexible spanner mouth (4) and fine setting screw engages.Being provided with swing jaw (1) and an a slice by pin (2) on the Flexible spanner mouth can make and swing the spring leaf (3) that jaw resets.Spring leaf one end be welded in or riveting on the Flexible spanner mouth, withstanding on the swing jaw of the other end removed outspoken velocity modulation to requiring the position in order to make activity, axially opens a U type groove what finely tune screw rod.On handle (6), be provided with a banking stop (5), make the Flexible spanner mouth can not extract handle out.There is an end face to be epicycloidal concave surface (9) on the mouth fixedly pulling of handle, because to back rotation, and when outwards twitching, the movement locus that nut is top to be pulled mouthful relatively is an epicycloid at handle, therefore when nut rotates, just can allow its drift angle at an easy rate in pulling mouth.As shown in Figure 2, when wrench opening is maximum, is provided with a screwdriver in Flexible spanner mouth rack end and stretches out from the Wrench head side, at this moment, this spanner is equivalent to a screwdriver that moment is bigger.Afterbody at handle is provided with the hexangle type through hole, can make fork spanner and use.

During work, spanner is put on the fastener, the U type groove of fine setting screw rod is facing to fastener, tooth bar on the Flexible spanner mouth breaks away from engagement with the fine setting screw rod at this moment, can securing member be clamped with the mobile Flexible spanner mouth of quick-moving speed, will finely tune screw rod again and change an angle fine setting till clamping.When pulling mouth when a certain direction is rotated, the automatic grip fastener of swing jaw, and make it to rotate, when rotating round about, the swing jaw just opens automatically, and allowed the diagonal angle of nut by the gerotor type concave surface, so that jaw two other plane of grip fastener again, visible function at this moment is equivalent to ratchet spanner, again because it is the opening adjustable wrench, therefore, concentrate the advantage of ratchet spanner and opening adjustable wrench, overcome both weakness.When needs are used screwdriver, screwdriver can be stretched out outside the handle, make the arm of force by means of handle, can twist the difficult screw that rises, the fork spanner that utilizes the hexagonal through hole of afterbody can make a certain specification is used.

High-efficiency clyburn spanner provided by the utility model compared with prior art has the following advantages:

1. the function that two kinds of functions of ratchet and adjustable wrench and screwdriver are arranged. Reach a kind of instrument Multiple use.

2. easy to operate, the work efficiency height facts have proved, generally can improve work efficiency 5-6 doubly.Can improve 10 times in narrow location.

The efficient adjustable wrench structural representation that description of drawings: Fig. 1 provides for the utility model.

Partial structurtes cutaway view when the efficient adjustable wrench opening that Fig. 2 provides for the utility model is maximum.

The efficient adjustable wrench that Fig. 3 provides for the utility model is along Fig. 2 A-A profile.
