Abstract

The utility model relates to a simple powerful double-mouth toothed pincers, which can be not only used to shear reinforcing steel bars used in concrete buildings but also used to crush or crack the bricks and tiles of building wall slabs and can be used as a tool for digging out people buried in collapsed buildings in particular. The head of a pincers body (7) is made into jaws (4); by means of pins (3), the heads (18) of the jaws (4) are respectively connected with an upper tooth (2) and a lower tooth (1) which can crush or crack the bricks and tiles of building wall slabs; the teeth, which can be large or small indented teeth, wavy teeth, and the like, can be replaced according to requirements and assembled outwardly; the inner edges of the jaws of the pincers body are made into spading edges (5) capable of spading nails and wood broken and shearing edges (6) capable of shearing reinforcing steel bars; the rear part of the pincers body (7) serves as a force arm part (8); and foldable stressing members, a supporting handle (10) and a forcing handle (11), are connected together by shaft pins (10, 13, 14).

Description

The simple and easy band of twoport energetically tooth pincers

1) technical field under

The utility model relates to tearing down and building of cement works body and uses tonger, especially a kind ofly promptly can shear the building of collapsing of being particularly suitable for that the reinforcing bar of using in the cement works body can sting essence again or crack construction wall plate ash tile block and rescues the simple and easy band of the twoport energetically tooth pincers that dig the personnel that buried by pressure.

2) background technology

At present, be used for earthquake and rescue and dig that to be embedded in the instrument of personnel in the building that collapses by pressure not really capable, function singleness, and very heavy, as: tonger has only the function of shearing the reinforcing bar of using in the cement works body; Method and the apparatus of removing construction wall are also only pounded, are prized and hammer, pick etc., and sound is very big.Can resemble silkworm eats the tonger that can bite body of wall ash brick the leaf into pieces and does not also have.

3) summary of the invention

In order to overcome the defective of existing building with apparatus such as pincers, hammer, pick, the utility model provides a kind of simple and easy band of twoport energetically tooth pincers, and the simple weigh light of this simple and easy band of twoport energetically tooth wrench structure is stung, cuts, shoveled, function such as support and active force be big.

The technical scheme that its technical problem that solves the utility model adopts is: the clamp head part of caliper (7) is made tiger arm (4) shape, go up to sting essence or crack the last tooth (2) that the grey tile block of construction wall plate uses at the tiger arm head (18) of tiger arm (4) and be connected with lower tooth (1) with pin (3), this tooth has large and small shaggy tooth and ripple tooth etc. several, can change on demand, and toothing outwardly (25) (seeing that Fig. 8 can be used to crack a broken and plane); Sword in the tiger arm of caliper is made the shovel mouth (5) that can shovel the disconnected wood of nail and the clip (6) of energy shear reinforcement; The rear portion of caliper (6) is pincers arm of force portion (8), last with pivot pin (10,13,14) with collapsible lever augmented member: help arm (10) with make arm of force handle (11) and be connected, there are different factures in pincers arm of force portions (8): symmetrical is the normal type pincers arm of force (15), and asymmetrical is that the special-shaped arm of forces (24) that clamp are seen Fig. 7.

The beneficial effects of the utility model are, the function that has kept the shear-steel muscle, increased the function of stinging essence or cracking the disconnected wood of construction wall plate ash tile block shovel nail, the improvement of the arm of force makes pliers not only keep the function that closing force is used to shear, and has also increased the function that the power of opening is used to crack.What increase makes the arm of force and can turn back to pack up and be easy to carry, and the active force of instrument increases, and function increases, and is suitable for the place and enlarges.

5) specific embodiment

The simple and easy band of twoport energetically tooth pincers as shown in Figure 1 are by caliper (7), lower clamp (17), go up tooth (2), lower tooth (2), pincers arm of force portion (9), help arm (11) with make the arm of force (12) etc. are formed by pin (3) and pivot pin (8.10.13.14) and fastening mother (16).

Last tooth (2) as shown in Figures 2 and 3 and lower tooth (1) divide have little recessed tooth (19) as Fig. 2 show, little double wedge (20) as Fig. 3 show, big recessed tooth (21) as Fig. 4 show, big double wedge (22) shows with ripple tooth (23) as Fig. 5 and shows several standards as Fig. 6.

The pincers arm of force portion (9) of the simple and easy band of twoport energetically tooth pincers is as shown in Figure 7 made by the asymmetrical special-shaped pincers arm of forces (24).
