Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0021] Such as Figure 1~4 As shown, a labor-saving PVC pipe cutter includes a left handle 2 and a right handle 1 hinged to each other. The upper end of the left handle 2 is provided with a blade groove 21 for inserting the blade 3. The blade 3 is C-shaped. The blade 3 It is arranged in the blade groove 21 and fixed by the screw 12 and the nut 13. The blade 3 is a toothed blade with serrations 31 on the lower end surface. Shaped concave surface, the bottom edge adjacent to the knife edge is a straight edge, the top edge away from the knife edge is arched, and the sides on both sides have arc transitions, forming a similar D-shaped profile. The wall thickness of the blade 3 at the concave surface 32 is controlled within an appropriate range Inside, the maximum size of the concave surface 32 is usually that its base is greater than the outer di...

Abstract

The invention discloses a PVC pipe cutter, comprising a cutter body formed by hinging a left handle and a right handle. A pipe groove is formed in the upper part of one handle; and a blade is fixed onthe other handle. The PVC pipe cutter is characterized in that a thinned concave surface for reducing the contact between the blade and a PVC pipe is formed on at least one of the front surface and the rear surface of the rear side of a cutter edge of the blade; the blade is a toothed blade; and the rear end of the cutter edge of the blade is thinned, so that when a pipe is cut, large-area contact between the blade and the pipe can be reduced, the extrusion feeling is reduced, and the function of quickly and lightly shearing the pipe is achieved. The PVC pipe cutter is more reasonable in structure, more convenient and labor-saving to operate and lower in manufacturing cost.

Description

technical field [0001] The invention relates to a cutting knife, in particular to a labor-saving PVC pipe cutting knife for cutting pipes. Background technique [0002] The pipe cutter can be applied to pipe cutting of various materials, and has the advantages of a large diameter span and no chips. PVC pipe cutters are mainly used for cutting PVC pipes. Most of the existing PVC pipe cutters are pliers type, mainly composed of large and small handles, push and pull pawls, tail buckles, some springs, blades and ratchets. However, the existing PVC pipe cutter has the disadvantages of laborious cutting and insufficient lightness, and the operation is laborious and inefficient. [0003] After investigation, the existing Chinese patent No. CN200720107773.5 "Pliers Type PVC Pipe Cutter With Portable, Quick and Automatic Knife Retraction" includes a pliers body composed of a small handle and a large handle, and matching blades and ratchets. , large screw, adjusting block and match...
