Description
Technical Field
The utility model relates to a C type locking pliers of adjusting binding clip length belongs to locking pliers instrument technical field.
Background
The locking pliers not only have large clamping force, but also have the locking function, the C-shaped locking pliers can clamp a workpiece in large size due to the long pliers head, and the deep and wide pliers head can span for clamping, so the C-shaped locking pliers are widely applied to manufacturing, assembly and maintenance workplaces, the C-shaped locking pliers mainly have two forms at present, namely a fixed pliers head and a movable pliers head, and the standard of the C-shaped locking pliers in China has three specifications, namely 125mm,150mm and 250mm. Due to the rapid development of the current society, the sizes of workpieces needing to be clamped and processed in the work of people are larger and larger, the working environments are different, and the requirements for clamping the workpieces are more and more, so that the specifications of C-type locking pliers in the market are developed to more than 10, wherein the maximum specification reaches 600mm, and as long pliers heads of the locking pliers are rigid structures which are riveted by single sections or three sections, a user needs to be provided with a plurality of pliers in different use environments, so that the pliers are inconvenient to carry and high in cost.
There is a 480mm C adjustable locking pliers on the market, the fixed head and the movable head of the pliers are welded with a 40mm square hole sleeve, the long head of an L-shaped rod is arranged in the sleeve, the pliers change the length of the pliers through the extension and the shortening of the long head of the rod in the square hole sleeve, the short heads of the L-shaped rod are oppositely arranged, the workpiece is clamped by a movable claw at the top end of the L-shaped rod, when the L-shaped rod is shortened due to 250mm, the rod tail extending out of the square hole sleeve is respectively positioned above and below the plier handle, the tail rod extending out of the fixed head above influences the gripping of the hand of the user, and the tail rod extending out of the movable head below influences not only the gripping of the hand, but also collides the hand of the user when the head is unlocked and opened, therefore, the two forceps heads of the pair of pliers have to be bent by a large angle at the rear part of the square hole sleeve, so that the hands of an operator have a safe distance when holding and unlocking the pliers, the special pair of pliers structure realizes the adjustment of the length of the forceps heads, but influences the use function of the pliers, the clamping points of the pliers and the pliers bodies are not in the same plane due to the bending of the forceps heads, users feel unaccustomed, the centers of the pliers and the pliers bodies deviate, the use also feels labored, a large operation space is occupied when the pliers are used, and meanwhile, the structure is not suitable for manufacturing small specification sizes, because if the safe distance between the hands and the pliers bodies is obtained when the hands are operated, the bending of the forceps heads is inevitably large, and the pliers cannot be used.
