Description

Multi-purpose tool

The utility model relates to a kind of hardware ﹠ tools.

Existing adjustable wrench generally can only nutting etc. has the part of faceted pebble, because it is to tighten part by the reaction force of faceted pebble.Owing to the screw pitch of adjusting the jaw distance is bigger, draw back once the screw rod of exerting oneself slightly when twisting the tubular part with adjustable wrench, therefore card does not live round piece.And existing pipe wrench generally can only be twisted circular part, because it is the wedge surface principle opposite with direction of rotation by jaw, the chucking round piece.When being screwed with the part of faceted pebble with pipe wrench, the wedge surface of inclination will cause the line contact of faceted pebble in rotary course, the very fast rounding of part is damaged.

At the problems referred to above, the purpose of this utility model provides a kind of adjustable wrench of both can having worked as and uses, and can work as the multi-purpose tool that pipe wrench uses again.

For achieving the above object, the utility model is taked following design: a kind of multi-purpose tool, it comprises that one has the main handle of main jaw, it is characterized in that: it also comprises an adjusting rod and an auxilliary handle, described main handle middle part has a vertical groove, respectively has a horizontal concrete chute on the described main handle of described groove both sides, described adjusting rod head has a secondary jaw, the rear portion has screw thread, the middle part has a through hole corresponding with described horizontal concrete chute, described adjusting rod is inserted in described vertical groove, and pass described through hole with a pin described adjusting rod is slidably mounted in the described chute, one end of described auxilliary handle has an oblique through hole and a hinge hole, be screwed into a nut at described adjusting rod afterbody, the described oblique through hole of described auxilliary handle is enclosed within the middle part of the afterbody and the main handle of described adjusting rod, and hinged by described hinge hole and described main handle.

Described auxilliary handle can be installed in the top or the bottom of described main handle.

The contact site of the described nut of described auxilliary handle and described adjusting rod afterbody is a circular arc.

Described secondary jaw is withstood on the spring that is arranged in described vertical groove, make major and minor jaw in running order all the time, reduce noise simultaneously.

On described main jaw and secondary jaw, can the one gram silk edge of a knife be set correspondence, use with convenient combination pliers.

Gram silk edge of a knife shape on the described main jaw can be " W " shape.

Afterbody at described main handle is provided with a screwdriver fixture, uses with convenient screwdriver.

The utility model is owing to take above design, it has the following advantages: 1, the utility model is owing to be provided with a main handle with main jaw, be provided with a adjusting rod and an auxilliary handle simultaneously with secondary jaw, therefore when tightening circular or having the workpiece of faceted pebble, be to adjust apart from after blocking part, defeat nut on the adjusting rod by the leverage of auxilliary handle, thereby make it can not return the purpose that reaches the chucking different workpieces.2, the utility model is owing to be provided with a spring in vertical groove of main handle, spring withstands on the head of secondary jaw all the time like this, make secondary jaw and handle in running order all the time, simultaneously can stop adjusting rod in the chute of main handle, arbitrarily to rock, avoid rocking the noise that is sent.3, the utility model makes the utility model increase a gram silk function owing to correspondence on major and minor jaw is provided with a gram silk edge of a knife.Owing to the gram silk edge of a knife with main jaw one side is designed to " W " shape, therefore when shearing, jaw has the bending function, makes shearing more laborsaving simultaneously.4, the utility model is fixed and placing device owing to the afterbody at main handle is provided with a screwdriver, makes function of use of the present utility model advance an expansion.The utility model can substitute multiple instrument, both can make things convenient for work on the spot, can reduce the burden of the instrument of carrying again.Especially the go out maintenance personal of work or use in the family, all very convenient.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.

As shown in Figure 1, the utility model comprises main handle 10, adjusting rod 20 and auxilliary handle 30.As Fig. 2, shown in Figure 3, main handle 10 heads have a main jaw 11, and the front portion has a vertical groove 12, and vertically correspondence has a pair of horizontal concrete chute 13 on the main handle 10 of groove 12 both sides.The middle part of main handle 10 has a hinge hole 14.As Fig. 4, shown in Figure 5, the head of adjusting rod 20 has a secondary jaw 21 corresponding with main jaw 11, the front portion have one with the corresponding through hole 22 of chute 13 on the main handle 10, the rear portion of adjusting rod 20 is screw threads 23.As shown in Figure 1, adjusting rod 20 is inserted in vertical groove 12 of main handle 10, pass through hole 22 and chute 13, main handle 10 and adjusting rod 20 are slidingly connected, nut 24 of cover on screw thread 23 with a pin.As Fig. 6, shown in Figure 7, the head of auxilliary handle 30 has an oblique through hole 31, at the corresponding hinge hole 32 of hinge hole 14 that has on the auxilliary handle 30 of oblique through hole 31 both sides on a pair of and the main handle 10.As shown in Figure 1, the oblique through hole 31 of auxilliary handle 30 is enclosed within the middle part of adjusting rod 20 afterbodys and main handle 10, passes hinge hole 14 and hinge hole 32, will assist handle 30 and be hinged on the main handle 10 with a pin.

In the foregoing description, should do in the arc-shapedly, as shown in Figure 1, rotate so flexibly assisting handle 30 and the contact site of the nut 24 of adjusting rod 20 afterbodys, stressed reasonable.In addition, a spring 40 can be set in vertical groove 12 of main handle.The diameter of spring 40 is a bit larger tham the width of vertical groove 12, spring can be stuck between two chutes 13 like this, and withstand on the head of adjusting rod 20, make secondary jaw 21 and main and auxiliary handle 10,30 in running order all the time, can stop adjusting rod 20 in the chute 13 of main handle 10, arbitrarily to rock simultaneously and send the sound.Can also open a shrinkage pool 25 (as shown in Figure 4) at the head of adjusting rod, with the spring 40 into shrinkage pool 25 that crouches.Spring 40 can also take other form to install.

In the foregoing description, can on major and minor jaw 11,21, horizontal anti-slip tank be set, the groove 16,26 (as shown in Figure 1) with angle of inclination also can be set, to block the workpiece of classes such as hex nut easily.In addition, can also a pair of gram silk edge of a knife 17,27 be set correspondence on major and minor jaw 11,21, the utility model just can be worked as the combination pliers use like this.As shown in Figure 8, the gram silk edge of a knife 17 on the main handle 10 can be designed to " W " shape (the general gram silk edge of a knife 17 is identical with 27 shapes).Like this, a gram silk edge of a knife not only has the strength of cutting in the time of use, and there is upward bent strength at the two ends of " W " shape, makes the gram silk easier.

In the foregoing description, a screwdriver fixture 18 and placing device 19 can also be set at the afterbody of main handle 10, increase a kind of function of screwdriver so again for the utility model.When a maintenance personal goes out work, only need be with this use novel, just can carry out basic operation.In the family, if a utility model is arranged, general work just can have been done.
