Specific embodiment

Below with reference to each attached drawing, by specific embodiment, the utility model in detail, completely describe.

It please refers to shown in Fig. 1-2, the utility model provides a kind of pliers, including binding clip 1, the first clamp handle 2, the second clamp handle 3 And eccentric fixed pin 4, the first clamp handle 2 are connect with binding clip 1 with the second clamp handle 3, the first clamp handle 2 and the junction of binding clip 1 are The junction of first tie point 5, the second clamp handle 3 and binding clip 1 is that the second tie point 6, the first clamp handle 2 and the second clamp handle 3 pass through partially Heart fixed pin 4 is hinged, can adjust the first tie point 5 and the by eccentric fixed pin 4 according to the size and material of different articles The distance of two tie points 6, to realize the corner dimension adjusted between the first clamp handle 2 and the second clamp handle 3, clamp operation is not only very It is laborsaving, and when repairing installation to certain more complicated installations and facilities, do not need to carry it is more various sizes of pliers, It is easy to use.

Eccentric fixed pin 4 includes pin shaft 41 and axle cap 42, and pin shaft 41 is obliquely installed on axle cap 42, the first clamp handle 2 and the Two clamp handles 3 are fixed by different positions in the axial direction of pin shaft 42, to the first tie point 5 and the second tie point 6 Distance is adjusted.

Pliers further includes backing stop structure, and backing stop structure is set between the first clamp handle 2 and the second clamp handle 3, for when without outer The masterpiece used time limits the movement of the first clamp handle 2 and the second clamp handle 3, and the first clamp handle 2 is in the lock state with the second clamp handle 3 at this time, To limit the opening distance of binding clip 1, so that binding clip 1 clamps article, not needing to clamp manually, when operation, is more laborsaving, and Article will not fall off or be displaced, and it is accurate to clamp position.

Backing stop structure includes the first retaining part 71 and the second retaining part 72, and the first retaining part 71 is set in the first clamp handle 2, Second retaining part 72 and the second clamp handle 3 are hinged, and the first retaining part 71 is equipped with several locking tooths 711, the second retaining part 72 be equipped with The retaining pawl 721 that locking tooth 711 is meshed, retaining pawl 721 is meshed with locking tooth 711 and the second pincers of limitation when without external force The automatic moving of handle 3, fit system is simple, and structure is reliable.

First retaining part 71 is structure as a whole with the first clamp handle 2, and manufacture craft is simple, solid firm, it is not easy to damage.

Pliers further includes the first dynamic clamping head and quiet clamping head 8, and the both ends of the first dynamic clamping head and quiet clamping head 8 are separately connected the second clamp handle 3 and Two retaining parts 72, when retaining pawl 721 is detached from locking tooth 711, the first dynamic clamping head and quiet clamping head 8 resets the second retaining part 72. Preferably, the first dynamic clamping head and quiet clamping head 8 is spring, and deformation occurs under external force, is restored to the original state again after removing external force, thus band Dynamic second retaining part 72 resets.

Pliers further includes the second dynamic clamping head and quiet clamping head 9, and the second dynamic clamping head and quiet clamping head 9 is sheathed on outside eccentric fixed pin 4, and the second bullet Property return unit 9 both ends be against the two sides of binding clip 1 respectively so that binding clip 1 opens automatically, operate more laborsaving.

The lateral surface of first clamp handle 2 and the second clamp handle 3 curves inwardly, and according to the principle of ergonomics, clamp handle has Certain radian, it is more laborsaving, convenient for holding.

Anti-slip cover is arranged with outside first clamp handle 2 and the second clamp handle 3, the material of Anti-slip cover is rubber or plastics, in use, increasing The frictional force for adding hand and the first clamp handle 2 and the second clamp handle 3, prevents pliers from slipping, and rubber and plastics are good insulating body, When in electrical field in use, situations such as electric shock can be effectively prevented.

The above is only the preferred embodiments of the utility model, not thereby limit the patent protection model of the utility model It encloses, it is all with equivalent structure transformation made by the utility model specification and accompanying drawing content, directly or indirectly it is used in other Relevant technical field similarly includes within the protection scope of the present utility model.
