Hand-hold pincers with parallel jaws

Abstract

The invention relates to a hand-hold pincers with parallel jaws, which comprise a movable pincer, a fixed pincer and a fixed seat, wherein the movable pincer is pivoted with the fixed seat; a translational component is also arranged; a translational slide block and the fixed pincer are always parallel in the clamping process through the position matching of a guide rod, the translational slide block and the fixed pincer, which ensures that a clamped element can be stressed evenly in the clamping process and is not easy to slip; and a reset element is also arranged and can push back the translational slide block and the movable pincer together after the clamping action is completed so as to facilitate operation. The hand-hold pincers can also be used for clamping seals; the fixed pincer and the translational slide block can be provided with impression blocks with anti-counterfeiting marks so as to strengthen the anti-counterfeiting function of lead seals; simultaneously, the hand-hold pincers are also provided with a limit non-return component, so a lead seal cannot be taken out between the impression blocks even though the lead seal is not clamped halfway in the clamping process, and the hand-hold pincers clamp the lead seal to a preset thickness and then loosen the lead seal so as to improve the security of the lead seal.

Description

technical field [0001] The invention relates to a hand tool, in particular to a hand-held pliers with parallel jaws. Background technique [0002] In the prior art, the two jaws of the hand-held pliers complete the clamping action at a certain angle. The Chinese patent No. CN99103236.5 discloses a safety tongs. "X" shape, the two jaws are always at a certain angle during the clamping process until the jaws are completely closed, and the clamping force at each point in the jaws is uneven, and the clamped part is prone to slipping during the clamping process Phenomenon. Contents of the invention [0003] The purpose of the present invention is to provide a hand-held pliers with parallel jaws, which has a simple structure, the two jaws are always kept parallel during the clamping process, the clamped parts are evenly stressed in the jaws, and the operation is convenient. [0004] Above-mentioned technical purpose of the present invention is achieved through the following te...
