Description

Tube knife capable of drilling various material

A kind of pipe cutter that bores multiple material, it relates to the daily hand-held tool of boring.

In the general daily life, often need on materials such as rubber, timber, leather, cardboard, hole, the method of drilling normally adopts bit drills system, but must rely on electric drill when boring system, even aid or equipment such as drilling machine, thereby it is extremely inconvenient, it is more inconvenient when particularly family uses, and running into need when soft materials such as rubber, leather are holed, utilize drill bit also can't process, can only adopt iron nail or chisel to cut a hole system bit by bit with conventional approach, thus take a lot of work, time-consuming, hand is vulnerable, and the circular hole of making, circularity and size are all undesirable.

The purpose of this utility model is to bore the difficulty in rounding hole by hand on multiple soft material and propose a kind of profile and draw the problem that cutter solves processing circular hole on multiple soft prepared material for the T tube shape in order to overcome in the daily life.

The utility model is realized by following measure.It is fixed into a T font integral body by cross bar and montant.Cross bar is a flat strips body, and one of right-hand member system can be hung the cross bar hole of depositing, but the through hole or the screwed hole of a compression fit of side system, and montant is cylindrical, is shaped on several cutting pointed tooths on the termination.There is a dark blind hole center, cuts open the hole in the side that its outside diameter surface has a confession to withdraw from smear metal.

This utility model has following advantage:

1, it has solved daily life, particularly needs to bore on than soft material the difficult problem in rounding hole in the family, and it can be on rubber, leather, cardboard, plank, and is convenient, promptly process and need the measured circular hole of matter.

2, can be used to replace tradition to use that the bank cutter is opened tropical fruit (tree), coconut is got the Coconut Juice method, and replace holing, can prevent that coconut palm water from flashing and meet hygienic requirements with this hand-held tool, and safe and reliable.

Accompanying drawing and drawing explanation:

1 one kinds of pipe cutter stereograms that can bore multiple material of accompanying drawing

Accompanying drawing 2 the utility model operation charts

1 cross bar, 2 cross bar hole, 3 through holes or screwed hole, 4 montants, 5 sides are cutd open hole, 6 cutting pointed tooths, 7 glued boards, 8 dark blind holes.

Below by embodiment and accompanying drawing a kind of pipe cutter that bores multiple material of the utility model is described further:

It is pressed into riveted joint or is utilized screw thread to spin by cross bar 1 and montant 4 and constitutes a T font integral body.Cross bar 1 adopts No. 20 steel plates to make the prolate bar shaped, makes through hole or the screwed hole 3 that gently is press-fitted, the cross bar hole 2 that is used for depositing extension in one of one side system of cross bar at middle side; Columniform montant 4 adopts the manufacturing of T8 carbon steel, in dark blind hole 8 of bottom face center system, on the cross bar external diameter, mill and make the sidepiece hole 5 that cutting is withdrawed from a confession, be shaped on several cutting pointed tooths 6 on the bottom face, montant is quenched, be pressed into again or screw in through hole or the screwed hole 3, and become the pipe cutter of a T shape integral body, as shown in Figure 1, the surface is carried out coated and is handled and to form.Its operation method as shown in Figure 2.

Claims

A kind of pipe cutter that bores multiple material is characterized in that, it is fixedly connected into a T font integral body by cross bar (1) and montant (4), and cross bar is the flat strips body, and right-hand member has one can hang the cross bar of depositing (2), and a through hole or screwed hole (3) are arranged in the middle of the side; Montant (4) is cylindrical, is shaped on several cutting pointed tooths (6) on the bottom face, in a dark blind hole (8) is arranged in the heart, be shaped on the side that a confession withdraws from cutting at external diameter surface and cut open hole (5).
