Description

Multipurpose pliers

The utility model belongs to the hand tools that is used to dismantle.Clamp especially for screw-nut clamping location before rotation or in rotating.

Existing machinery, electric equipment manufacturing industry widely use screws bolts to be connected and fixed each member in the equipment, also all have a large amount of screws bolts to connect parts on transport facility such as automobile, the bicycle.The said equipment member, parts part burn out rust bad time, and it is bad that the screws bolts screw thread also all burns out rust, and lose between screws bolts and the parts and closely cooperate and form and burn out the bad space of rust, at this moment, pour and renew bolt screw work and be difficult to carry out.Because local necrosis, bad old screws bolts can not be taken out, and chewing the common hand tools of pincers or the like with a flat mouth clamp, point can not holding workpiece, can only block screws bolts with percussion tools such as hacksaw and drift, hand hammer hand chisels in the practice.But use hacksaw will be subjected to spatial constraints, percussion tools such as drift then can damage equipment, and some hot line jobs also can cause security incident to take place.So far, the hand tools that is suitable for of Shang Weiyou is used to pour when changing screws bolts clamping location is dismantled.

The purpose of this utility model is to provide a kind of multipurpose plier, improves on the basis of common tongs hand vice, has V-shaped groove owing to improve the back at jaw, has solved clamp screws bolt location dismounting problem.What have also simultaneously that point chews pincers, cutting pliers cuts the folder function, is a kind of multipurpose plier.

But this multipurpose plier has 2 identical moving calipers 1, and the two is fixed as central movable by latching 2, and its afterbody is handle 4 and is coated with insulation sleeve; But also has cutting edge mouth 32 moving caliper 1 interlocks place, but this cutting edge mouth 3 is positioned at pin 2 by moving caliper 1 head one side, but feature is moving caliper 1 a head jaw has V-shaped groove 6, but the opening of V-arrangement is in a side of moving caliper 1, but the summit of V-arrangement is in the side in addition of moving caliper 1, but 1 head jaw interlock place of one side moving caliper also has folder hole 5 on the V-arrangement summit; Have teeth groove 7 in the above-mentioned V-shaped groove 6.

The utility model is simple in structure, and the workman is easy for operation, has solved in the work practice and has removed bad old screws bolts clamping orientation problem, reduces labor intensity greatly.Damage equipment not, and safe in utilization.Simultaneously, also possess and generally cut the folder function.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the utility model structural representation;

But Fig. 2 is V-shaped groove 6 structural representations that moving caliper 1 head jaw possesses, and is the A-A section of Fig. 1;

But Fig. 3 is moving caliper 1 structural representation, is the B-B section of Fig. 1.

With reference to Fig. 1～Fig. 3, but the utility model has V-shaped groove 6 at moving caliper 1 head jaw on common tongs hand vice basis, and the V-arrangement fixed angle is 90 °, but along with handle 4 moving calipers 1 open, the V-arrangement fixed angle also opens width for 90 °, and at this moment jaw increases.Folder hole 5 is to be used for fishbolt.Change rust during bad bolt when pouring, but open moving caliper 1, the V-arrangement apex end of V-shaped groove 6 is snapped in the gap of the arbitrary end of bolt, fishbolt, the teeth groove 7 that has in the V-shaped groove 6 increases the rotational resistance of bolts or nut.Behind the clamped location of bolt, end successfully takes out bolt with spanner or screwdriver in addition.Along with the back-out of bolt, pinching end also moves up along with V-shaped groove 6, has so just guaranteed all the time to take out the rotational resistance of bolt, thereby has poured the downright bad bolt that swaps out.

Claims (1)

1, a kind of multipurpose plier, but identical 2 moving calipers [1] had, the two is fixed as central movable by pin [2], and its afterbody is handle [4] and is coated with insulation sleeve; But also have cutting edge mouth [3] in 2 moving calipers [1] interlock place, this cutting edge mouth [3] is positioned at pin [2] but by moving caliper [1] head one side, it is characterized in that:

But moving caliper [1] head jaw has V-shaped groove [6], but the opening of V-arrangement in a side of moving caliper [1], but the summit of V-arrangement in the in addition side of moving caliper [1], but one side moving caliper [1] head jaw interlock place also has folder hole [5] on the V-arrangement summit; Have teeth groove [7] in the above-mentioned V-shaped groove [6].
