Abstract

The utility model relates to a multifunctional combined clamp with a replaceable jaw, belonging to the technical field of hand tools. The utility model is formed by that clamping blocks with different-purpose jaws are transformed and installed on a combined clamp arm for a large-opening clamp with teeth. The utility model solves the problems of single function, high acquisition cost and inconvenient large piece clamping of an existing integral clamp. The utility model is suitable for various handwork operation, such as clamping large-caliber and small-caliber columns, flat plates and flexible pipes, pressing electric wire terminals, inserting and breaking pressure tanks, etc.

Description

Multifunction combined clamp with interchangeable jaw

The utility model belongs to field of hand.Relate to a kind of multifunction combined clamp with the interchangeable jaw of multiple different purposes.

Existing manual clamp mostly is monolithic construction, small-bore as shown in Figure 1 and Figure 2 band tooth pincers and flat-nose pliers, shown in Figure 3ly dehisce greatly to clamp and the broken pressure clamp etc. inserted that reclaims discarded tin can that is exclusively used in shown in Figure 4 all has only single function, under the job requirement of the multiple function of needs, must purchase multiple tonger, expense height not only, it is also big to take up room.And the pincers of dehiscing greatly wherein shown in Figure 3 also need to grip and could clamp with palm when the clamping larger object, use that both inconvenience was also unreliable.

The purpose of this utility model is that a kind of large and small clamping bore that has, the jaw of replaceable multiple different purposes, easy to use and reliable multifunction combined clamp will be provided.

Above-mentioned purpose is realized by following scheme:

Multifunction combined clamp with interchangeable jaw, form by caliper and holder arms, the caliper bottom is a lever, it is characterized in that, described holder arms is that a pair of microscler holder arms and symmetrical rivet clasp form the clamp of dehiscing greatly in caliper top, each is combined this holder arms by the identical intermediate plate of two plate shapes, homonymy two intermediate plates are by the less straight-neck rivet riveted in a pair of stage casing jack-post diameter big two ends riveting axis of a cylinder footpath, form the structure of hollow between two intermediate plates, in this space inner conversion the various grip block with different purposes jaws is installed, is utilized two bending embedding port recess of this grip block vice jaw surface opposite side one side that its buckle is locked the clamp that is combined into interchangeable jaw on the straight-neck rivet stage casing jack-post between two intermediate plates and with screw.

Jaw pattern with various grip block of different purposes jaws includes: heavy caliber jaw, small orifice jaw, dull and stereotyped tong chops, hose clamp jaw, wire terminal bar hold and slotting broken pressurized tank jaw.

The specially made structure that strengthens the jaw bearing capacity is: the part beyond grip block embeds between two intermediate plates, both sides end face respectively thicken the end that leans that its outer margin arc-surface of one deck and the grip finger internal tooth of dehiscing greatly join.

Avoid the clamp combined altitudes to be subjected to the specially made structure of the holder arms of working space restriction to be: two pairs of equal dog legs of intermediate plate extremely are the position of parallel misalignment with caliper.

Below in conjunction with description of drawings embodiment:

Embodiment 1:

Fig. 5 and Fig. 6 are foundation structure pattern one big opening clamp of the present utility model.The hypomere of caliper 1 is a lever, the epimere of caliper 1 and two

microscler holder arms

2,3 riveted joints,

holder arms

2,3 forms big opening clamping jaw, caliper 1 can be the structure that is fixed into the one interlock with

holder arms

2,3, also can be as Fig. 5, shown in Figure 6 holder arms 2 be made movable structure, promptly make holder arms 2 unidirectional foldings, when

drawing lever

10,11 snap closes 4 location in by means of the lock catch arm 4 that is installed on the caliper 1, holder arms 3 location fastenings, holder arms 2 system of exerting pressure is transferred the object pincers tight.On the inside arc shape clamping face of two

holder arms

2,3, respectively be shaped on two

rows folder tooth

20,30 at interval, every row has 4 monodentates, two holder arms, 2,3 tops do not contact, be applicable to the big footpath of clamping object, the open and close movement track of

holder arms

2,3 is similar to parabola, thereby all can be retained to rare relative three row folding teeth can effectively contact the clamping object when clamp different-diameter object.Above-mentioned

holder arms

2,3 is respectively constituted by two identical shaped

intermediate plates

21,22 and 31,32, all be shaped on the

circular hole

23,33 of 2 spacing symmetries on each intermediate plate, the bigger straight-neck rivet 5 of the less stage casing of two ends riveting post 51 diameters 50 diameters of axle, form structure with its riveted joint and between two intermediate plates, have the grip block 6 of the various jaw of different purposes in order to converting means with spacing L hollow.Wherein Fig. 7, Figure 8 shows that the structure that grip block 6 is installed, the clamping face of this grip block 6 is made difform jaw according to the clamping purposes, the other end then is shaped on two

buckle grooves

61,62 relatively, in order to chimeric with the stage casing cylinder 50 of the straight-neck rivet 5 of riveting

intermediate plate

21,22 and 31,32, thereby grip block 6 is embedded the hollow part of

intermediate plates

21,22 and 31,32, it is fastening with screw 7, packing ring 8 again by screw 210 and 310.The conversion pattern of above-mentioned grip block 6 jaws is in respect of hose clamp jaw (as Fig. 7), tubule brank mouth (as Figure 10), dull and stereotyped tong chops (as Figure 11), wire terminal bar hold (as Figure 12), slotting broken pressurized tank jaw (as Figure 13) etc.

The different shape that the

buckle groove

61,62 of above-mentioned grip block 6 can be made into as shown in Figure 9 is to reach best chimeric effect.

Embodiment 2:

When need with folder energetically when pulling object, lean end 63 (see figure 10)s for what can respectively thicken that its outer margin arc-surface of one deck and the clamp

internal tooth

30,20 of dehiscing greatly join at the part both sides end face beyond grip block 6 embeds between two

intermediate plates

21,22 and 31,32.

Embodiment 3:

For the clamp combined altitudes of avoiding dehiscing greatly is subjected to the restriction of working space, the

intermediate plate

21,22 and 31,32 of

holder arms

2,3 can adopt two-way bending to make the structure 9 (seeing Figure 14) that is parallel misalignment with caliper 1.Also convertible installation has the grip block 6 (seeing Figure 15) of different types jaw in the

holder arms

2,3 of the clamp of dehiscing greatly.

Owing to adopt technique scheme, the utlity model has of many usesly, folder is pulled firmly anti-Press, use reliable convenient and economical and practical advantage.
