Abstract

The utility model relates to a powerful pliers, which comprises a clamping part, a regulating part, and a holding and loosening part, wherein, one head of a regulating threaded bolt of the regulating part is connected with a nut of a movable block, and the movable block is connected with a supporting rod. When the regulating threaded bolt rotates, the size of an opening of a pliers head can be regulated for clamping objects with corresponding size. The utility model has the advantage of convenient operation.

Description

A kind of locking pliers

The utility model relates to the manufacturing of Hardware pliers class, specifically is a kind of locking pliers.

The adjustment structure of existing locking pliers, the tail end inner chamber of its pincers handle is provided with internal thread, regulates bolt and screw-internal thread fit, and the size of jaw is regulated in advancing or going out of swivel bolt, and it is dumb to regulate operation, and the rotation amplitude is excessive, can make the adjusting bolt falling; The internal thread machining of pincers handle is complicated, increases man-hour and cost.

The utility model is in order to overcome the weak point of existing locking pliers governor motion, and it is out of control to avoid regulating bolt, and it is a kind of by regulating bolt that design provides, and movable block and pole constitute the locking pliers of governor motion.

The conception plans of this locking pliers includes: clamping part is made up of two binding clips, regulates parts by the pincers handle, pole, and movable block and adjusting bolt are formed; Clamping and loose part are by loosening bar, holding handle and torsion spring and extension spring, two binding clips flexibly connect, the same binding clip of handle is fixedly linked, in the inner chamber of fluting, be equipped with by regulating the governor motion that parts are formed: regulate bolt one end and be positioned at the handle tail end by catch, the other end nut in the movable block groove that is threaded, the movable block other end links to each other with pole, flexibly connect holding handle by pole again, loosening bar is fixedly connected on by rivet and torsion spring in the inside groove of holding handle, the part upper surface of its outer edge contact pole.

The utility model has improved existing locking pliers by regulating the structure that bolt is threaded with handle, adopt and regulate bolt with the nut thread connection that places the movable block groove, during operation, rotation is regulated bolt and is not easy to come off, easy to use, the shortcoming of solution handle internal thread machining difficulty.

Below, press accompanying drawing in conjunction with the embodiments, details are as follows to technology contents of the present utility model:

Fig. 1 is the utility model topology view.

As shown in the figure, binding clip 1 is by rivet 3 fixedly connected handles 5, and binding clip 1 and 2 structure can adopt forging, and casting or powder die-casting are made, and binding clip 1 of the present utility model is made up of the identical binding clip sheet of 3-5 sheet tooth portion with 2.Handle 5 is provided with slotted inner chamber, and the open slot of side communicates with inner chamber within it.Another binding clip 2 inboards are flexibly connected by rivet 4 and binding clip 1, and the outside is by rivet 13 fixedly connected holding handles 15.The inner chamber of handle 5 is provided with governor motion; Regulate bolt 11 and be fixed on handle 5 tail ends by catch 10, the nut 9 that 11 1 on adjusting bolt is placed at together in groove of movable block connects, bolt 11 is regulated in rotation, drive movable block 8 upper and lower slips through nut 9, the other end of movable block 8 links to each other with pole 6 by pin 7, and the other end of pole 6 connects holding handle 15 through rivet 16, the upper and lower effect of moving and passing through holding handle 15 of movable block 6, reach the openings of sizes of regulating binding clip 1 and 2, the gripping objects of the corresponding size of clamping.Loosening bar 19 by rivet 18 and around the home the two on rivet 18 be positioned at torsion spring 17 on holding handle 15 and the loosening bar 19 and be fixed in the inside groove that holding handle 15 offers, manually loosening bar 19 makes the bottom of the part upper surface bump pole 6 of its outer edge, holding handle 15 is flicked by the pulling force effect that is connected the extension spring 14 between handle 5 and the binding clip 2, drive binding clip 2 by rivet 13 and open, unclamp gripping objects.
