Abstract
The utility model relates to a multi-jaw pliers, which belongs to a hand tool. The utility model is composed of a big half pliers handle (1), a small half pliers handle (2), a big half pliers head (18) and a small half pliers head (5). The big half pliers head and the small half pliers head are positioned and hinged at the end section of the big half pliers handle (1) and the small half pliers handle (2) through pin rolls (3), which can open and close. The big half pliers head (18) is additionally provided with a movable lug mechanism. When the utility model is used for screwing a screw cap, a pliers jaw does not need to retire from the screw cap and can screw continuously. So the work efficiency is enhanced.
Description
The utility model relates to a kind of Multi-jaw pliers, belongs to hand tools.
Existing hand vice are to be combined into integral body by two and half pincers, clamp down on object and cut off wire etc. as long as the actuating handle can be finished, and can not use it for anything else, so the purposes dullness; Though a kind of improved multipurpose plier is arranged, it is with the combination of hand vice and adjustable wrench, but makes it not only can make hand vice but also double as adjustable wrench usefulness, has widened purposes.But, when turning nut, whenever turning once, jaw must be recessed nut, thereby can not realize turning continuously after interlock, influences operating efficiency.
Task of the present utility model is to provide a kind of jaw to need not to recess the Multi-jaw pliers that nut just can turn continuously once interlock.
Task of the present utility model is finished like this, a kind of Multi-jaw pliers, by large and small half pliers grip (1), (2) be positioned at large and small half pliers grip (1), (2) end and form by large and small partly binding clip (18), (5) that both of bearing pin (3) hinge can open/close, now do improvement, on more than half pincers binding clips (18), set up movable lug mechanism.
The utility model is being owing to setting up movable lug mechanism on more than half pincers binding clips (18), when turning nut, need not make jaw recess nut and can turn continuously, improved operating efficiency.
Below in conjunction with accompanying drawing the utility model is further described below.
Fig. 1 is a structure chart of the present utility model.
Movable lug of the present utility model mechanism by with the threaded rod framework (14) of more than half pincers binding clip (18) integral production, be located at the movable lug seat (13) on the threaded rod framework (14), the movable lug (9) that is connected with the upper end of movable lug seat (13) by movable lug axle (12) and screw shaft (16) and the threaded rod (17) that movable lug seat (13) is moved that matches with the screw thread bar (15) of integral production in movable lug seat (13) bottom that rotate around screw shaft (16) of being located on the threaded rod framework (14) are formed.On threaded rod framework (14), have groove, the bottom of movable lug seat (13) is located in this groove, be made with screw thread bar (15) in movable lug seat (13) bottom, match and can make the move left and right groove of whole movable lug seat (13) on threaded rod framework (14) in by screw thread bar (15) and threaded rod (17), thus the size of adjustment jaw (8).
Movable lug of the present utility model (9) can make movable lug (9) change the opening angle of jaw (8) around movable lug axle (12) swing certain angle by the active upper end that is connected movable lug seat (13) of movable lug axle (12).Be to play to make movable lug (9) be in the location and be in rotary state with the effect of two movable lug jaw locating pieces (10) of movable lug (9), movable lug seat (13) integral production, (11) respectively.The edge of a knife (4) is cut off the usefulness of iron wire etc.
When the utility model uses, stir threaded rod (17) with hand, thereby make in the groove of movable lug seat (13) on threaded rod framework (14) by screw thread bar (15) and to move, make the live house (9) of loose joint on movable lug seat (13) cooperate smaller part pincers pincers tongue (7) interlock nut (6).When movable lug (9) when opening, smaller part pincers pincers tongues (7) and the formed jaw of movable lug (9) (8) be greater than nut (6), and institute is so that interlock nut (6) and unclamp hand vice.In addition, because the swing of movable lug (9) is that guide effect is arranged, so as long as will large and small half pliers grip (1), (2) do one and low-anglely freely swing for a short time, just can make the S limit interlock of smaller part pincers pincers tongues (7) and nut (6).Because the effect of lever, movable lug (9) position is in place and nut (6) stung tightly enter duty.When turning large and small half pliers grip (1), (2) certain angle, nut (6) is just corresponding to rotate to an angle, and when hand vice withdraw from very a little bit smaller apart from the time because nut (6) still is in nut (6A) position in the jaw (8A).Can oppositely turn large and small half pliers grip (1), (2) certain angle so need not make hand vice recess nut (6) fully, at this moment nut (6) is touched the inner edge of movable lug (9) and is become the inner edge that the D edge joint touches movable lug (9A) gradually by former S edge joint, thereby promotes movable lug (9) opened with certain angle to movable lug (9A) position.Repeating above-mentioned steps just can screw nut (6) fast or unscrew.
Claims (2)
1, a kind of Multi-jaw pliers, by large and small half pliers grip (1), (2) be positioned at large and small half pliers grip (1), (2) end and form, it is characterized in that setting up movable lug mechanism most clamping on the binding clips (18) by large and small partly binding clip (18), (5) that both of bearing pin (3) hinge can open/close.
2, Multi-jaw pliers according to claim 1, it is characterized in that movable lug mechanism by with the threaded rod framework (14) of more than half pincers binding clip (18) integral production, be located at movable lug seat (13) on the threaded rod framework (14), the movable lug (9) that is connected with the upper end of movable lug seat (13) by movable lug axle (12) and screw shaft (16) and the threaded rod (17) that movable lug seat (13) is moved that matches with the screw thread bar (15) of integral production in movable lug seat (13) bottom that rotate around screw shaft (16) that is located on the threaded rod framework (14) form.
