Description
Technical field
The utility model belongs to a kind of machining tool, is specifically related to a kind of locking pliers of clamping.
Background technology
Be used for common tool that slim workpiece such as clamping sheet metal processes at present and be the pliers of a lever principle of utilization such as common pliers, when holding workpiece, owing to directly have an effect by people's hand, be directly conducted to workpiece by a lever, cause clamping force less, clamped workpiece is got loose, and operation effort and clamping effect are bad.
Summary of the invention
The purpose of this utility model is: the big and operation of a kind of clamping force type locking pliers of twitching one's mouth easily is provided.
The purpose of this utility model is achieved in that the type locking pliers of twitching one's mouth, comprise tong arm and following tong arm, the fixedly connected pincers of going up of the head of last tong arm are chewed, being positioned at pincers chews the head of last tong arm of below and is hinged down to clamp and chews, the other end that following pincers are chewed is hinged with an end of following tong arm, the middle part of following tong arm is hinged a motion bar, protrude downwards at the middle part of motion bar, the other end of motion bar is arranged in the tong arm, between the middle part that described pincers are down chewed and the middle part of last tong arm inboard extension spring is set, the described afterbody of going up tong arm is provided with the adjusting bolt, and make the adjusting bolt prop up an end of the motion bar in the tong arm, the described afterbody of tong arm down is hinged a depression bar, and an end of depression bar is arranged on the below at protrusion place, described motion bar bottom; Described upward pincers are chewed the relative part of chewing with following pincers and are fixedly installed a flat clamp respectively.
The utility model is owing to there is motion bar to be connected between tong arm and the following tong arm, constituted the secondary lever, when holding workpiece, only need very little power workpiece can be clamped, last pincers are chewed with the flat clamp that clamps the relative part setting of chewing down and can firmly sheet-like workpieces such as sheet metal be clamped, depression bar on the following tong arm is used to provoke the protrusion place of motion bar, two pincers is chewed opened; The effect of extension spring is to chew when clamping at two pincers, makes it the clamping force that keeps certain, regulates bolt and is used to regulate motion bar in the position in last tong arm, and the opening and closing degree change that pincers are chewed can adapt to different workpiece processing requests.
In sum, the big and operation of the utility model clamping force easily.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, straight shape of the mouth as one speaks locking pliers, comprise tong arm 5 and following tong arm 3, the fixedly connected pincers of going up of the head of last tong arm 5 chew 7, being positioned at pincers chews the head of last tong arm 5 of 7 belows and is hinged down to clamp and chews 8, the end that following pincers are chewed 8 the other end and following tong arm 3 is hinged, the middle part of following tong arm 3 is hinged a motion bar 4, protrude downwards at the middle part of motion bar 4, the other end of motion bar 4 is arranged in the tong arm 5, following pincers are chewed between the middle part of 8 middle part and last tong arm 5 inboards extension spring 6 are set, the afterbody of last tong arm 5 is provided with regulates bolt 1, and make adjusting bolt 1 prop up an end of the motion bar 4 in the tong arm 5, and the afterbody of following tong arm 3 is hinged a depression bar 2, and an end of depression bar 2 is arranged on the below at protrusion place, motion bar 4 bottom; Last pincers chew 7 and clamp down and chew 8 relative part and fixedly install a flat clamp 9 and 10 respectively.
