A vise with replaceable blades

Abstract

The invention discloses a blade-replaceable vice which comprises a vice head and a vice handle. The vice head comprises a left vice head and a right vice head which are mutually matched. A left clamping groove for assembling a left blade is formed in the left vice head. The left clamping groove comprises a groove bottom, a left groove opening, a right groove opening and an upper groove opening. The section of the groove bottom is larger than that of the upper groove opening. The section of the right groove opening is larger than that of the left groove opening. The left blade is fixed in the left clamping groove through a left bolt. The cutting edge of the left blade is linear. A right clamping groove symmetrical to the left clamping groove is formed in the right vice head. A right blade symmetrical to the left blade is assembled into the right clamping groove. The cutting edges of the left blade and the right blade are provided with arc-shaped wire stripping openings which are matched. The blade-replaceable vice is simple in structure, the blades can be replaced conveniently, the waste vice due to abrasion of the cutting edges can be reused, and the shapes of the cutting edges can be changed to allow the vice to have multiple functions.

Description

technical field [0001] The invention relates to a vise, which belongs to the technical field of electric power fittings. Background technique [0002] The vise is a commonly used tool in electric power construction. The jaws can be used to bend or clamp the wire ends; the teeth can be used to fasten or loosen the nuts; Guillotine cut wire core, steel wire and other hard wire. The vise on the market is divided into alloy steel vise and high carbon steel vise. The price of alloy steel vise is about 400 yuan / piece, and the price of high carbon steel vise is about 20 yuan / piece. Although alloy vise has excellent performance, wear resistance and service life are better than High carbon steel vises, but are not widely used because of their high price. [0003] After the high carbon steel vise is used for a period of time, the following problems will occur due to wear and tear: the knife edge is severely cracked, and steel wire and iron wire cannot be cut; the knife edge is passi...

AI Technical Summary

Problems solved by technology

[0003] After the high carbon steel vise has been used for a period of time, the following problems will occur due to wear and tear: the knife edge is severely cracked, and steel wire and iron wire cannot be cut; the knife edge is passivated, and the wire cannot be stripped;

Since the knife edge and the pliers body are an integrated structure, the worn knife edge cannot be re-polished, and many vises will be discarded just because the knife edge is worn out, resulting in a serious waste of resources.
