Description

Multi-functional leakproof pipe is cut

Technical field

The utility model relates to a kind of pipe to be cut, and especially relates to a kind of multi-functional leakproof pipe and cuts.

Background technology

In industrial and agricultural production and daily life, pipes such as plastic-aluminum pipe, plastic tube have substituted traditional galvanized pipe, are widely used in running water and other fluid tube at present.The great advantage of the use of these plastic-aluminum pipes, plastic tube etc. is easy for installation.Install with the process that is connected in shear with pipe and to cut, but in use, tend to cause external diameter distortion in the pipe after pipe is cut off, so need could connect then with a kind of full circle mouth expander at first with its full circle enlarging.The defective that rounding device now commonly used exists be can only full circle can not enlarging and chamfering, and and pipe cut and do not connect together, use and cumbersome when carrying.

Summary of the invention

The purpose of this utility model is to cut at above-mentioned pipe the problem of rounding device, provides a kind of multi-functional pipe easy to use to cut.

In order to achieve the above object, the utility model mainly is achieved through the following technical solutions.The utility model is cut institute by pipe and is formed, described pipe is cut the fixedly edge of a knife and the movable edge of a knife that comprises that pipe is cut, fixedly the edge of a knife is connected handle respectively with the movable edge of a knife, be provided with the full circle enlarging chamfering device of taper in the main body section of scissors, the full circle enlarging chamfering device of this taper can be the pyramidal structure of triangular and the above many ribs of triangular; Also can be conical, pagoda shape structure; It also can be the sheet pyramidal structure; And the full circle enlarging chamfering device of this taper can be arranged on each position that pipe is cut, as the afterbody of cutting handle at pipe, on the handle that pipe is cut, in the rotating shaft that pipe is cut or the like.

The utility model compared with prior art has following obvious advantage and innovation.(1) simple in structure.This practical structure that has changed traditional rounding device is cut rounding device and pipe dexterously and to be combined.As long as be with pipe to cut, rounding device also therein.(2) easy to use.Because this rounding device can be arranged on each position that pipe is cut as required, use and make full use of the leverage that pipe is cut, very laborsaving, the full circle enlarging is effective.(3) cost is low.Because the utility model is pipe to be cut with putting in order the enlarging chamfering device combine dexterously, has reduced the cost that traditional rounding device is a stand-alone product.

The utility model is applicable to that pipe cuts.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

The specific embodiment

As shown in Figure 1, the utility model is cut institute by pipe and is formed, described pipe is cut the fixedly edge of a knife 2 and the movable edge of a knife 1 that comprises that pipe is cut, fixedly the edge of a knife 2 is connected handle 3,4 respectively with the movable edge of a knife 1, be provided with the full circle enlarging chamfering device 5 of taper in the main body section of scissors, the full circle enlarging chamfering device 5 of this taper can be the pyramidal structure of triangular and the above many ribs of triangular and taper shape, pagoda shape structure.

As shown in Figure 2, full circle enlarging chamfering device 5 of the present utility model is the sheet pyramidal structure, and the position is at the afterbody of handle.

As shown in Figure 3, full circle enlarging chamfering device 5 of the present utility model is a conical structure, and the position is at the middle part of handle.

As shown in Figure 4, full circle enlarging chamfering device 5 of the present utility model is the plane pyramidal structure, and the position is in the rotating shaft of handle.

The utility model is applicable to that pipe cuts.

Claims (1)

1. a multi-functional leakproof pipe is cut, cutting institute by pipe forms, described pipe is cut the fixedly edge of a knife (2) and the movable edge of a knife (1) that comprises that pipe is cut, fixedly the edge of a knife (2) is connected handle (3) and (4) respectively with the movable edge of a knife (1), the theme position that it is characterized in that scissors is provided with tapered full circle enlarging chamfering device (5), and the full circle enlarging chamfering device (5) of this taper is the pyramidal structure of multiple shape.
