Embodiment Construction

[0020] Such as Figures 1 to 4 As shown, the tweezers of the present invention include two clamping arms 1 and clamping ends 3, the ends of the clamping arms are connected to the clamping ends, a pair of blades 2 that are staggered and tangent are arranged at the ends of the two clamping arms, and the joints near the head ends of the two clamping arms are provided. There is an adjustment rotating shaft 4 that runs through the two clamping arms.

[0021] The pair of blades and the two clamping arms are integrally formed by extending, bending and flattening the ends of the two clamping arms inwardly. When the clamping arms are opened and closed, the cutting edges of the two blades form a notch with each other. The blade 2 is composed of the extension part 6 of the clamp arm, the cutting plane 7 and the cutting edge 8 of the blade. The angle between the extension part of the clamp arm and the clamp arm is 60-80 degrees. The arm extension forms the facet, and the edge of the face...

Abstract

The invention discloses a pair of tweezers, which simultaneously has a clamping function and a cutting function, can clamp for a long time and is labor-saving and convenient. The tweezers are provided with a pair of blades integrated with two arm locks. Cutting edges of the two blades can form a shear mouth through opening and closing the two arm locks, so that objects can be cut, and when the arm locks are completely closed, the blades are stored between the two arm locks in a staggered manner; the opening and closing angles of the arm locks can be regulated and locked through arranging a regulating rotating shaft, so that an operator does not need to apply force to the arm locks continuously; the tail ends of the arm locks are maintained to be connected with clamping ends, so that the clamping function of the tweezers is not influenced.

Description

technical field [0001] The invention belongs to tweezers. Background technique [0002] Common tweezers only have a clamping function, and other tools must be used when cutting or cutting operations are required, which is less efficient. There have been some tweezers with detachable blades on the market, which have better flexibility but complex structures and high manufacturing process requirements. In actual use, the repeated disassembly and assembly of the blades will aggravate the wear and deformation of the connecting mechanism and greatly shorten the service life. In some experimental production operations, it is required to continuously clamp the same object for a long time. If ordinary tweezers are used, the fingers need to continue to exert force on the clamp arm, which is not only laborious but also prone to finger fatigue, causing the object to fall and unnecessary damage. loss. Contents of the invention [0003] The technical problem to be solved by the prese...
