The inner surface of the upper grip head has been placed equidistant with fixture block, the inner surface of the upper grip head and opens up between adjacent upper fixture block
There is a upper card slot, the inner surface of the lower pliers head equidistantly offers lower bayonet slot, the inner surface of the lower pliers head and is located at adjacent lower card
Lower fixture block is provided between slot.
Preferably, the section of the lower pliers head and upper grip head is in curved nozzle type duckbill structure.
Preferably, the lower surface of the lower pliers head is welded with locating piece, and the inner rotation of locating piece is connected with compression bar.
Preferably, the compression bar is two-part structure, one end is screw thread rod structure, and the other end is circular plate structure.
Preferably, there are three the upper fixture block and lower bayonet slot be respectively provided with, and three upper fixture blocks and three lower bayonet slots are two-by-two
Between correspond clamping.
Preferably, there are three the lower fixture block and upper card slot be respectively provided with, and three lower fixture blocks and three upper card slots are two-by-two
Between correspond clamping.
Preferably, the arc end outer surface of first clamp handle and the second clamp handle is enclosed with non-slip leather case.
The utility model provides a kind of gripping tongs of curved nozzle type, have it is following the utility model has the advantages that
(1), the gripping tongs uses the tong head of curved nozzle type, is capable of increasing the clamping force of binding clip, facilitates operator
Rotation clamp handle is operated, while the fixture block and card slot of the one-to-one correspondence structure in the setting of the corresponding surface of upper grip head and lower pliers head,
So that realizing the clamping corresponding with card slot of the fixture block of corresponding position to above and below clamping object when lower pliers head and upper grip head closure clamping
The clamping effect of both direction further increases the clamping force of binding clip, and preventing binding clip, there is a situation where slip.
(2), the gripping tongs by setting compression bar, and threaded rod one end of compression bar can rotate in locating piece thus
The amplitude size that compression bar removes locating piece is adjusted both to avoid to play the effect that limit is adjusted to the rotational steps of clamp handle
Clamp handle rotates excessive phenomenon, while also can timely adjust clamp handle rotational steps, meets different use demands.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.
Referring to Fig.1-3, a kind of gripping tongs of curved nozzle type, including lower pliers head 1, upper grip head 2, the first clamp handle 4 and the second clamp handle
8, it is rotatablely connected between the first clamp handle 4 and the second clamp handle 8 by pin shaft 3, the inner surface of upper grip head 2 has been placed equidistant with fixture block 9,
The inner surface of upper grip head 2 and card slot 10 is offered between adjacent upper fixture block 9, the inner surface of lower pliers head 1 equidistantly offers
Lower bayonet slot 12, the inner surface of lower pliers head 1 and is provided with lower fixture block 11 between adjacent lower bayonet slot 12.
The section of lower pliers head 1 and upper grip head 2 is in curved nozzle type duckbill structure, and the lower surface of lower pliers head 1 is welded with locating piece
6, and the inner rotation of locating piece 6 is connected with compression bar 7, compression bar 7 is two-part structure, and one end is screw thread rod structure, the other end
For circular plate structure, can rotate compression bar 7 makes it remove or move into locating piece 6, so that the rotational steps to the second clamp handle 8 rise
To the effect of clamping position, prevent the second clamp handle 8 from rotating excessively, there are three upper fixture block 9 and lower bayonet slot 12 are respectively provided with, and on three
Fixture block 9 and three lower bayonet slots 12 correspond clamping between any two, there are three lower fixture block 11 and upper card slot 10 are respectively provided with, and three
Lower fixture block 11 and three upper card slots 10 correspond clamping, the arc end outer surface of the first clamp handle 4 and the second clamp handle 8 between any two
It is enclosed with non-slip leather case 5.
Working principle: in use, palm when held the first clamp handle 4 and the second clamp handle 8, cooperation non-slip leather case 5 is capable of increasing hand
Frictional resistance between the palm and clamp handle, prevents the phenomenon that slipping out of the hand, by upper grip head 2 and lower pliers head 1 close to clamping object, rotation
The first clamp handle 4 and the second clamp handle 8 are opened, separates it under the rotary action of pin shaft 3 by upper grip head 2 and lower pliers head 1, when upper pincers
First 2 and lower pliers head 1 when clamping object, rotating the first clamp handle 4 and the second clamp handle 8 makes its closure, at this time upper grip head 2 and lower pliers head
1 closure, at the same time, upper fixture block 9 and lower fixture block 11 touch clamping object first, with the gradually closure of binding clip, then upper to block
The phenomenon that block 9 and lower fixture block 11 can be gradually increased the chucking power to object, prevent clamping object from falling off, and do not pressed from both sides in binding clip
When holding, upper fixture block 9 and lower fixture block 11 can be respectively embedded into lower bayonet slot 12 and the inside of upper card slot 10 carries out embedded storage, another party
Face, rotation compression bar 7 change its amplitude for removing locating piece 6, clamp handle are enabled to play the work of position limitation protection when rotating to clamp handle
With, prevent clamp handle rotation excessively, then the gripping tongs completely uses.
