Description

Multifunctional spanner

The utility model belongs to metalworking tool, relates to a kind of multi-functional wrench furtherly.

Aborning, the use of wrench is extremely general, and screw tap hinge hand also often uses, and usually, wrench and screw tap hinge hand are two kinds of instruments that independently separate, and its shortcoming is:

One, inconvenience keeping is easy to lose.

Two, make separately, waste raw material, cost is higher.

The purpose of this utility model be to provide a kind of cost lower, be convenient to keeping, multi-functional wrench easy to use.

The purpose of this utility model is achieved in that it promptly is that screw tap is cut with scissors the middle part that hand is arranged on the wrench body, is combined into a multi-functional wrench.

Be arranged on the jaw of the screw tap hinge hand at wrench body middle part, can fix, also can be adjustable, jaw size can be regulated by the fine-tuning nut that is contained on the active chuck, the top of active chuck is two cones of 90 °, and the opening of opening between the cone and fixed chuck body constitutes the square jaw of screw tap hinge hand, the adjustable clamp of screw tap hinge hand, in use, locate by screw.

The screw tap hinge hand that is arranged on wrench body middle part is formed by metal material thickening forging, to solve the problem of undercapacity.

Multi-functional wrench chuck constitutes on the plane of jaw, also can leave zigzag, and the size of jaw can be fixed, also can be adjustable, the size of jaw is regulated by regulating knob, has the multi-functional wrench of zigzag adjustable jaw, can replace pipe wrench to use.

Multi-functional wrench of the present utility model, owing to be screw tap to be cut with scissors hand be combined on the wrench, thereby overcome two kinds of metalworking tools, the inconvenience keeping, the shortcoming that is easy to lose, jaw, screw tap hinge hand vice mouth owing to the wrench chuck is adjustable again, and therefore, the scope of application is extensive, and have zigzag on the plane of wrench Chuck jaw, therefore, except can screwing out complete corner and hex screw, nut, be particularly useful for face damage screw, nut.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Accompanying drawing is the schematic diagram of multi-functional wrench.

Multifunction board handbag rubbing board head, handle (7), screw tap hinge hand, the jaw that is made of active chuck (1), fixed chuck (3) on the wrench is regulated by regulating knob (2), has zigzag groove on the face of jaw interlock object.

Screw tap hinge hand comprises adjustable clamp (4), dog screw (5), fine-tuning nut (6) and hinge hand fixed chuck body (8).Make the slotted eye of assembling adjustable clamp (4) and fine-tuning nut (6) on the fixed chuck body (8), the front portion of adjustable clamp (4), centre position in both sides, run through whole front portion and be shaped on slotted eye, dog screw (5) is fastened in the slotted eye, adjustable clamp (4) is positioned, and adjustable clamp (4) can be under the effect of fine-tuning nut (6), slides in front and back.The diameter at the middle part of adjustable clamp (4) is less than the diameter of front portion, the middle part of adjustable clamp (4) is shaped on screw thread, fine-tuning nut (6) is enclosed within on the screw thread at adjustable clamp (4) middle part, interlock mutually, turn fine-tuning nut (6), adjustable clamp (4) is seesawed, bite or unload object.The diameter at the rear portion of adjustable clamp (4) is less than the diameter at middle part.The length of the slotted eye of assembling adjustable clamp (4) is greater than the length of adjustable clamp (4), and its length is with adjustable clamp (4) interlock or unload the seesaw mountain pass that is not obstructed of object and be advisable.Be shaped on hanging hole (9) on the handle (7).The pyramid tip of adjustable clamp (4) and fixed chuck body (8) respectively are shaped on one 90 ° opening, and being fitted to each other becomes a sizable square jaw (10), thereby constitute screw tap hinge hand portion.

Claims (3)

1, a kind of multi-functional wrench comprises wrench, handle (7), it is characterized in that the middle part of wrench body is provided with screw tap hinge hand.

2, as said multi-functional wrench in the claim 1, the size that it is characterized in that screw tap hinge hand vice mouths (10) is to align by the fine-tuning nut (6) that is arranged on the adjustable clamp (4), and jaw (10) is foursquare.

3, as said multi-functional wrench in the claim 1,2, it is characterized in that wrench is provided with by regulating the adjustable clamp (1) that knob (2) is regulated, adjustable clamp (1), fixed chuck have zigzag on (3).
