The utility model comprises a movable tong head with tong teeth, a motive concave chute which is provided with a movable tong head, a tong body which can cause the tong head to open and close, and a tong handle which can cause a jaw to self lock, wherein, the movable tong head is sheathed in the concave chute of the tong head; the tong handle is fixed on the tong body through a pin axle and a retainer ring. The tong handle and the movable tong head are mutually matched through a lug boss and a pit, on one hand, the movable tong head can be slid in the concave chute of the tong body, and the tong head can be freely opened and closed; on the other hand, a lock axle is matched with a slotted hole of the pin axle on the tong body, the jaw is self locked, and the utility model plays the action of a spanner and a pair of powerful tongs.

Description

The multifunctional water pump pliers

The utility model relates to a kind of five metals clamp type tool.

Existing water pump pliers is mainly used in clamping, screws columniform pipe fitting and other larger-size part.This water pump pliers mainly is divided into sliding pin shaft type, tongue-and-groove stacked-up type and pincers cheek sleeve type three major types by its structure, and its major defect is that function and purposes are single.Like this, in carrying out multiple multi-form operation process, the user must carry multiple different types of clamp type tool, just can finish several work.Brought inconvenience to the user thus.

In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of several work such as can pull, clamp, lock, compress each type objects, and is not only laborsaving, use but also multifunctional water pump pliers easily.

The purpose of this utility model is achieved like this:

The utility model is combined as a whole the design feature and the function of water pump pliers, spanner, locking pliers and sharp Zi, one of the lunar mansions pincers, designed a binding clip that has the activity that clamps tooth, one have special construction, be provided with the cephalomotor spill chute of adjustable clamp, and can make binding clip folding caliper and pincers handle that can make the jaw self-locking freely.The adjustable clamp headgear is contained in the spill chute of caliper, the pincers handle is fixed on the caliper by bearing pin and back-up ring, pincers handle and movable binding clip cooperatively interact by its boss and concave point, on the one hand movable binding clip are free to slide in the spill chute of caliper, make movable binding clip folding freely; Also can make the jaw self-locking on the other hand, play the effect of spanner and locking pliers by the bearing pin slotted hole cooperation mutually on lock shaft and the caliper.

The utility model through after the above-mentioned design compared with prior art, has the following advantages:

1, be skillfully constructed, simple and reasonable for structure, one-piece parts is few, be convenient to the assembling.

2, multiple functional.Because its movable binding clip can parallel free folding, and has auto-lock function, therefore, it not only can be used as spanner and uses, but also can be used as water pump pliers, locking pliers uses.

3, handsome in appearance, easy to use.Because its pincers handle is longer, is convenient to hold, so when use is very laborsaving.

Specific embodiments of the present utility model is as shown in drawings:

Fig. 1 is a structural representation of the present utility model

Fig. 2 is the structural representation of the movable binding clip of the utility model

Fig. 3 is that the A-A of the movable binding clip of the utility model is to schematic diagram

Fig. 4 is the structural representation of the utility model caliper

Fig. 5 is the structural representation of the utility model pincers handle

Below in conjunction with accompanying drawing, concrete structure of the present utility model is elaborated:

The multifunctional water pump pliers includes movable binding clip 1, caliper 2,3 three parts of pincers handle, and movable binding clip 1 is sleeved on the caliper 2, and pincers handle 3 is fixed on the caliper 2 by bearing pin 4 and the back-up ring 5 that is half cylindrical structure.At the nip part of movable binding clip 1 and caliper 2, be provided with pincers tooth 6; At the back of movable binding clip 1, be provided with concave point 7 and groove 8; In groove 8, be provided with protruding rail 9.For simplifying the manufacture craft of movable binding clip, movable binding clip 1 can be divided into two of symmetry, by riveted it is integrated.On caliper 2, be provided with movable binding clip groove 8 in protruding rail 9 the spill chute 10 and the bearing pin slotted hole 11 that match.The depth of parallelism of the opening when guaranteeing that movable binding clip opens, spill chute 10 is set in parallel with bearing pin slotted hole 11.11 overlapping forming of circular hole by a plurality of same diameter of the center of circle on same axis of bearing pin slotted hole, the periphery of bearing pin slotted hole 11 are many circular arcs and connect.Head at pincers handle 3 is provided with boss 12; Cooperatively interacting of concave point 7 on boss 12 and the movable binding clip 1, the jaw switching mechanism of formation water pump pliers; By pulling pincers handle 3, movable binding clip 1 is free to slide in the spill chute 10 of caliper 2, make the binding clip folding freely.And the peripheral bearing pin slotted hole 11 that is many circular arcs connections matches with the bearing pin 4 that is semi-cylindrical in configuration, then constitutes the self-locking mechanism of water pump pliers jaw opening; By pulling and matching with the circular arc of holding clencher handle 3, making on the bearing pin slotted hole periphery that is on semi-cylindrical lock shaft 4 and the caliper 2, can make open jaw self-locking, play the effect of spanner and locking pliers.

Working method of the present utility model is achieved like this:

With the hands hold the caliper 2 and the pincers handle 3 of multifunctional water pump pliers respectively, pull pincers handle 3 with the right hand, concave point 7 on the boss 12 promotion activity binding clips 1 of pincers handle 3 heads makes protruding rail 9 in the movable binding clip groove 8 along moving in the spill chute 10 that matches with it on the caliper 2, and jaw is freely opened; If will regulate the opening width of jaw, then can move the position of bearing pin 4 in bearing pin slotted hole 5 and realize by pincers handle 3.At this moment, if with the hands hold pincers handle 3 with a firm grip, can make movable binding clip tightly clamp object according to shouldering rod principle, thereby make it play the function of water pump pliers and locking pliers.Because the spill chute 10 on the caliper is set in parallel with bearing pin slotted hole 11, therefore, when open movable binding clip what position in office, all be parallel open.Like this, just make water pump pliers have the function of monkey wrench again.In addition, because the periphery of bearing pin slotted hole 11 is many arc structures, it matches with the bearing pin 4 that is semi-cylindrical in configuration, then can constitute the self-locking of water pump pliers jaw at arbitrary aperture position.
