Abstract

The utility model relates to a pair of shears for cutting plastic pipes. The shears are provided with a left and a right handles symmetrically hinged and shears blades connected with the handles. Cutting edges are arranged on the shears blades, and arc-shaped grooves are arranged at the cutting edge part of any shears blade. The number of the arc-shaped grooves is two. When the shears are used for cutting plastic pipes of polyvinyl chloride (PVC), etc, pipes on which cutting lines are drawn are put in the arc-shaped grooves, the cutting lines are parallel and level with the arc-shaped grooves, and then, the pair of handles are tightly grasped to make the cutting edge of the other shears blade apply stable shearing force on the pipes. The pipes can be accurately sheared along the cutting lines without adopting complicated fixing measures for the pipes, and the cutting surfaces sheared are smooth. Plastic pipes of polyvinyl chloride (PVC), etc can be simply and accurately cut by the shears.

Description

Cutting plastic pipe scissors

Technical field

The utility model relates to a kind of scissors, particularly relates to a kind of cutting plastic pipe scissors.

Background technology

At present, often adopt saw blade to cut plastic pipes such as PVC.During cutting, generally on the outer wall of tubing, draw line of cut and begin cutting from line of cut.Need in the cutting process tubing is taked loaded down with trivial details fixation, move, the accuracy of influence cutting to avoid the tubing position; In addition, can't guarantee in the cutting process that the center line of saw blade and tubing is perpendicular all the time, cause the cut surface out-of-flatness, also need again tubing to be processed processing.Therefore, how can cut plastic pipes such as PVC simple and direct, accurately is problem demanding prompt solution.

The utility model content

The technical problems to be solved in the utility model provides a kind of cutting plastic pipe scissors, adopts this scissors, can cut plastic pipes such as PVC simple and direct, accurately.

For solving the problems of the technologies described above, the utility model provides a kind of cutting plastic pipe scissors, and it has left-right symmetry and hinged a pair of handle and the shear blade that links to each other with handle, and shear blade is provided with cutting edge, and the cutting edge place of arbitrary shear blade is provided with arc groove.

For can concise description for the purpose of the problem, below this cutting plastic pipe be all abbreviated as this scissors with scissors.

When adopting plastic pipes such as this scissors cut PVC, the corresponding tubing that only needs to finish line of cut places in the arc groove, make line of cut concordant with arc groove, then, a pair of handle of firmly holding with a firm grip makes the cutting edge of another shear blade apply stable shearing force to corresponding tubing, like this, need not take loaded down with trivial details fixation to tubing, also corresponding tubing comparatively accurately can be cut off along line of cut, the cut surface that cuts is comparatively smooth.Therefore, adopt this scissors, can cut plastic pipes such as PVC simple and direct, accurately.

In addition, when adopting plastic pipe such as this scissors cut PVC, also have high efficiency, advantage that labour intensity is low.

The quantity of described arc groove is two.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

Below by embodiment and accompanying drawing thereof the utility model is described in further detail:

Referring to Fig. 1, handle 1 and handle 2 left-right symmetry and hinged by rotating shaft 3, the shear blade that links to each other with handle 1 is provided with cutting edge 4, and the shear blade that links to each other with handle 2 is provided with cutting edge 7, and cutting edge 7 places are provided with arc groove 5 (diameter is 25mm) and arc groove 6 (diameter is 32mm).

When adopting plastic pipes such as this scissors cut PVC, carry out according to following steps:

1) the Cutting Length size quantity with pvc pipe material (diameter is 25mm) is good, and finishes line of cut (not shown this tubing in the accompanying drawing);

2) this tubing is placed in the arc groove 5, make line of cut concordant with arc groove 5, then, firmly hold with a firm grip handle 1, handle 2, make 4 pairs of these tubing of cutting edge apply stable shearing force, and along line of cut to this pipe shearing one circle, until this tubing is comparatively accurately cut off, the cut surface that cuts of cleaning can come into operation a little.

Certainly, above-described only is preferred implementation of the present utility model, should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle, also can make some modification and improvement, these also should be considered as belonging to protection domain of the present utility model.

Claims

1. cutting plastic pipe scissors has left-right symmetry and hinged a pair of handle and the shear blade that links to each other with handle, and shear blade is provided with cutting edge, it is characterized in that: the cutting edge place of arbitrary shear blade is provided with arc groove.

2. cutting plastic pipe scissors according to claim 1 is characterized in that: the quantity of described arc groove is two.
