Abstract

The utility model relates to a tool, particularly a wrench. The utility model is composed of a palate 1 and a mandible 2 which is connected with the palate through pins 4. The utility model is characterized in that the palate 1 is provided with a through slot, and the mandible 2 in the through slot is connected with the palate 1 through pins 4; one end of a reed 3 is fixed on the palate 1 through screws 5, and the other end is clung to the back of the mandible 2. The utility model has the advantages of artful design, beautiful appearance, time saving and labor saving; the wrench having the functions of wrenches and control tongs can be widely used in all walks of life and family lives.

Description

Combination wrench

The utility model relates to a kind of general utility tool, particularly relates to a kind of spanner.

Spanner is the general utility tool commonly used that a kind of installation, maintenance equipment all need possess.Now Chang Yong spanner is commonly called as adjustable wrench, and it is made of spanner palate and spanner lower jaw, and palate and handle become one, and lower jaw links by screw thread and screw rod and palate, and the turn screw rod can make lower jaw move up and down, and palate and lower jaw clamp the object that need turn round.This adjustable wrench structure relatively but complicated, and palate is parallel with the lower jaw clamping area, and do not have the palate tooth, thus can only the angled object of spin crossover, as hex bolts etc.Slick and sly object then can not rotate, as pipe etc.For overcoming the deficiency of adjustable wrench, on sale on the existing market have a kind of spanner, is commonly called as fork spanner, it is made of palate and lower jaw, and lower jaw and handle become one, the palate tooth portion triangularity of palate, just become interior triangle with the palate tooth portion of lower jaw, the afterbody of palate has groove, is fixed on the lower jaw by pin, during use, movable before and after the palate, interior triangle palate tooth portion by palate and lower jaw clips object, holding getting final product of handle rotation for one, but the another hand will just tighten object according to palate.This Spanner structure is simple, easy to usely can revolve various cross sections and the object of shape, and the palate of blemish in an otherwise perfect thing is very easily swung, and one is unbecoming, and the 2nd, needing two hands to cooperate could use, and use occasion just is restricted like this, makes its purposes not extensive.

The utility model is a kind of novel spanner that designs at the deficiency of above-mentioned spanner, i.e. combination wrench.

The utility model is to realize like this, it by palate 1 with constitute with the lower jaw that is connected by pin 4, palate 1 becomes one with handle, and (upper and lower palate is an address, can exchange), be characterised in that palate 1 has groove, lower jaw 2 is connected with palate 1 by pin 4 in groove, and reed 3 one ends are fixed on the palate 1 by screw 5, and the other end is close to lower jaw 2 backs.

This reality and novel having the following advantages:

1. combination wrench integrates adjustable wrench and control pincers function, can pull the object that (revolving) twists all kinds of cross sections shape.For example: six sides, four directions, flat side, circle shape and irregularly shaped object.

2. the utility model can one-handed performance, and particularly for narrow place, the utility model can show that it is distinctive nimble, only clamps object combination wrench can being stretched into, and the utility model can load and unload.

3. in the work, after adjustable wrench is screwed to certain angle, in the time of can not continuing to screw, must unload lower ejector lever again, put again again and screw, repeatable operation like this, it is time-consuming to require great effort, and after the utility model puts workpiece, can realize operation repeatedly, need not unload by pine, finish up to operation, laborsaving saving time, nimble rapidly.

4. the utility model structure is novel, easily manufactured, cheap.

Fig. 1 is the utility model structural representation.Accompanying drawing also can make an abstract.

Fig. 2 is the attached view of the utility model structure.

Below in conjunction with accompanying drawing to this practical being described further.

The 1st, the utility model palate, it and handle become one, and palate 1 can directly be made of one with handle, perhaps becomes one with manner, for example pegs graft.Have groove in the middle of the palate 1, lower jaw 2 is connected with palate 1 by pin 4 in groove, and the size of groove is conveniently exceeded with lower jaw 2 activities.The back of lower jaw 2 (palate toothed portion dorsad) can be arc.Spring leaf 3 one ends are fixed on the palate 1 by screw, and the other end is close to the back of lower jaw 2, palate tooth position dorsad, and spring leaf 3 can be straight type, also can be arc, and for easy to use, an end of being close to lower jaw 2 backs preferably has bending.Here explanation a bit upper and lower palate is a kind of address, can exchange.

Embodiment 1, and palate 1 is made of one with handle, and the palate flank of tooth is an arc; The palate flank of tooth of lower jaw 2 also is an arc, and its radian and palate can be basic identical, and the back of lower jaw 2 is level and smooth arc, near afterbody one recessed song is arranged; Spring leaf 3 is an arc, and an end of contact lower jaw back has a bending, and the 3 one end bendings of original state (when promptly not using) reed are placed in the recessed song of lower jaw 2 afterbodys just.

Embodiment 2, and palate 1 is made of one with handle, and the palate flank of tooth is a del; The palate flank of tooth of lower jaw 2 is that the plane has tooth, and the palate flank of tooth becomes interior triangle with the lower jaw flank of tooth.All the other are with embodiment 1.

Above-mentioned two embodiment, palate 1 all has groove, and lower jaw 2 is connected with palate 1 by pin 4 in groove.

When the utility model uses, hold handle, finger pulls open mouthful (pulling lower jaw), is enclosed within on the workpiece that needs loading and unloading, unclamp finger, pull mouth and can rely on 3 times power of spring that workpiece is blocked, pull trigger piece then, the utility model can clamp workpiece automatically, load and unload, behind the completed loading, pull lower jaw 2, then the utility model unclamps workpiece.

The utility model integrates adjustable wrench and control pincers function, the usefulness of alternative two instruments, and novel in design again, weight is light and handy, and is specious, uses and saving of work and time, therefore can be widely used among all trades and professions and the family life.

Claims
