Description

Monkey wrench

The utility model relates to that pipe fitting, screw element are fastening, a kind of hand-operated tools of connection, dismounting or clamping.

At present, be used for that pipe fitting, screw element are fastening, the hand-operated tools of connection, dismounting or clamping, modal is pipe wrench and adjustable wrench, and they mainly are made of trigger piece and binding clip two large divisions, just some difference of structure of binding clip part, but all be folding with screw member control binding clip, the deficiencies in the prior art part mainly is: these two kinds of instruments have their own characteristics each, and stronger specific aim is arranged, and certain limitation is promptly respectively arranged, can not replace mutually, versatility is poor; In addition, no matter between each member of which kind of spanner the certain clearance amount need be arranged, have the outside component of different directions during use again, chucking power is little, so be easy to occur skidding, has to adjust repeatedly, find out optimum state, often is not use effectively, and usability is relatively poor.Be again,, need good several instruments alternately to change and use in some occasion, the one, convenience is poor, time-consuming bothersome, and the 2nd, cause the various in style of instrument.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of highly versatile, the universal type spanner product that usability is good.

Can take following technical scheme to realize purpose.Monkey wrench still is made of trigger piece and binding clip two large divisions, but its binding clip is by the bolt die (1) of trigger piece end and is hinged on the structure that the Flexible spanner hook (2) that matches on the trigger piece, with bolt die is constituted.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Accompanying drawing is a kind of structural representation of monkey wrench.

In the monkey wrench, bolt die (1) reaches the specific constructive form of the Flexible spanner hook (2) that matches with bolt die, the tooth form of bolt die, size, quantity, arrangement mode, pull the adaptable pipe fitting of width, thickness, size and binding clip of hook, the size range of screw element etc., all can be selected according to using needs to take the circumstances into consideration.They can be made serial monkey wrench product multi-form, different size.

In the monkey wrench example shown in the drawings, bolt die (1) is the circular-arc member of sawtooth.Also bolt die can be made the member of the form such as linearity, inner concavity of sawtooth or other profile of tooth or other geometry.

If the hook (2) of pulling of monkey wrench is made the interior flanging shape member that A, B limit are parallel to each other, be hinged on the trigger piece, match with it with bolt die in the accompanying drawing example, have best result of use.Bolt die and pull the bigger size scope of application is arranged between hook; Both can be used for pipe fitting, circular piece, also can be used for various flat thread spares or other member; It can be bitten member firmly, only there is centripetal force, not as any adjustment or centering, can effectively carry out fastening, connection, dismounting or the clamping operation of various members, be beneficial to strength, that locks more with strength is tight more, will never skid, save time and save trouble,, back out in the same old way even be the part that head of screw has been twisted circle; Chucking is fastening when forwards promoting, and when oppositely returning, unclamps automatically, need not to take off, can be continuously, operation incessantly; The occasion of every use pipe wrench and adjustable wrench, a monkey wrench just can be finished, and the scope of application is wide.When pulling hook and make other version, match with bolt die shown in the drawings, also have result of use preferably.

In order to increase function, enlarge the scope of application, monkey wrench in the legend also is provided with movable handle (3) in the appropriate position of holding in addition of trigger piece, its end be with trigger piece be rotationally connected, the other end also is provided with by bolt die (1) and be hinged on the tong head that the Flexible spanner hook (2) that matches on the movable handle, with bolt die is constituted, movable handle stop tab (4) is established in the corresponding position of trigger piece.Block is used for the location of movable handle; The binding clip at movable handle place can be made into the size range that is connected mutually with the trigger piece binding clip, 9～14,15～22 scopes as shown.

End place in addition at the monkey wrench trigger piece also can be provided with screwdriver (5), stay and pull mouthful (6, a 7) structure.Screwdriver available active handle is made the arm of force, strengthens to turn effect.

The relative prior art of the technical program has following advantage and effect:

1, highly versatile, an instrument can be finished the work of several general tools, The kind of instrument is reduced; Be suitable for many, the wide ranges of work post.

2, usability is good, the work efficiency height, and function is many, and is safe and reliable.
