Abstract
The utility model belongs to a hand tool which is pipe spanner, mainly comprising a flexible tong band and a spanner arm. The tong band can form a slipcover, namely, the pipe is sheathed by the jaw and is tightly tonged by the spanner arm. Thus the connection of pipes can be realized by converting the spanner arm again. The utility model has the advantages of duration and big adjustable range of the caliber, which can generate no impression and cracks at the place of the pipe connection and the advantage is shown up particularly in the connection of plastic pipes.
Description
The utility model belongs to a kind of hand tools, is a kind of bulldog wrench.
Existing this class instrument such as iron spanner exist some shortcomings like this: connect pipe and always stay tangible impression even crackle to pipe, plastic pipe is particularly evident; Have, jaw of spanner is very easy to wear again, uses and tells people to carry out orders with regard to bad soon; In addition, its bore adjustable extent is little, often will repeatedly use the iron spanner of different size in the pipe of various models connects instead, is very much trouble.
The purpose of this utility model just is to provide a kind of new-type bulldog wrench, and it is durable, the bore adjustable extent is big, stays impression and make it to crack especially can for coupled pipe.
The purpose of this utility model is achieved in that it comprises that mainly a brace arm and the flexible strap that can form jaw that plays the arm of force and the tight effect of pincers promptly clamps band, the two end respectively is with a transverse axis, these two transverse axis two ends are overlapped on on two pedestals, thereby brace arm and pincers band are connected as a single entity.Entangle pipe with the pincers band during use, the transverse axis with the brace arm band is a switching brace arm then, makes its end twist with the fingers the further tight pipe of pincers of pressing tongs band, pulls at last and presses brace arm to realize that pipe connects.
Further specify the utility model below in conjunction with instantiation.
Fig. 1 is a kind of concrete structure schematic diagram of the present utility model.
Describe structure of the present utility model and occupation mode in detail according to Fig. 1.
It comprises that pincers are with 7, brace arm 1, transverse axis 2,5, pedestal 3,4; The transverse axis 2 of brace arm head end can be pegged graft, transverse axis 5 preferably puts to roll to be rolled up to overlap with 7 head end by pincers again after 6 and ties down, pincers are with 7 can rotate freely around transverse axis 5 like this, transverse axis 2,5 two ends can be riveted on pedestal 3 respectively, on 4, occupation mode is: will clamp and be with 7 to be sandwiched in pedestal 3 around pipe, 4 from transverse axis 2,5 are passed, make pipe be enclosed within pincers with in 7 covers that form, and put forth effort to drag pincers and be with 7 to be locked up to pipe, pincers can allow it ride over naturally on the brace arm 1 with 7 parts of not overlapping pipe, serve as axle switching brace arm 1 with transverse axis 2 then, borrow its arc tip shape head end to twist with the fingers pressing tongs band 7, it is 7 tight with pipe vice that pincers are with, and pulls at last to press brace arm 1 to finish pipe to connect.
Pincers are with 7 can adopt the ox-hide band or add one deck flexible steel band again, also can accompany the belt of other material between ox-hide band and steel band again, and the ox-hide band is a nexine, and steel band is attached to the ox-hide band and simultaneously goes up as outer.Adopt the ox-hide band to be the enough softnesses of ox-hide and compression strength is big; antifriction and coefficient of friction are big; this facilitates pincers and is with 7 to be easy to form cover and the tight pipe of pincers under brace arm 1 effect; and do not stay impression to pipe; certainly the ox-hide band also can be had the material of similarity such as rubber covered wire belt to replace it by other; the outer purpose of steel band that adopts is to protect the ox-hide band, make it to be twisted with the fingers by brace arm 1 very soon to damage by pressure, but it should be very thin and soft.
Brace arm 1 head end is should be greatly a little and be preferably made the arc tip shape of evagination, and this is convenient to be with 7 to twist with the fingers and press more and more tightlyer on pincers, makes it to clamp tight pipe.
The spacing of transverse axis 2,5 should be as far as possible little, can be convenient to pincers and be with 7 to stretch through and get final product, and its benefit is: pipe Zhou Yuan nearly all can by pincers be with 7 around, such one is convenient to clamp tight pipe, two can make pipe stressed even and be difficult for the part and crack
The utility model has the following advantages:
1, it is good to connect quality: it be by flexible pincers band with pipe vice tight and realize not being subjected to what pipe connected, pipe hard press and week circle stressed evenly, so the pipe connection place impression can not occur very To crackle, this advantage especially looms large in the plastic pipe connection.
2, durable: the pincers band is not easy to wear, and it is influenced also little that it clamps tight effect even some weares and teares, so prolonged, durable.
3, the bore adjustable extent is big: because of the pincers band is not only soft but also long, so can form very little so that bigger pincers cover.
Claims (3)
1, a kind of hand tools, especially a kind of bulldog wrench is characterized in that: it comprises that mainly a head end crosses the brace arm 1 of transverse axis 2 and pincers that one one end is being fastened transverse axis 5 are with 7, and the two ends of transverse axis 2,5 all are overlapped on respectively on the pedestal 3,4.
2, by the described bulldog wrench of claim 1, it is characterized in that: pincers include as the ox-hide band that contacts one deck with coupled with 7.
3, by the described bulldog wrench of claim 2, it is characterized in that: pincers are with 7 also to comprise one deck flexible steel band.
