Description

A kind of manual simplified punch tool

Technical field

The utility model relates to punch device field, is specifically related to a kind of manual simplified punch tool.

Background technology

Existing boring device generally uses electric drill, but due to electric drill price more expensive, generally can not possess in every household, only professional staff just can possess; On the other hand, owing to electric drill to be had electricity just can hole, in the process of boring, noise is also bigger, inadequate energy-conserving and environment-protective. Traditional Manual drilling device generally uses circular level and smooth drill bit, does not have point of fixity in the process of boring, especially, when carrying out rubber plug and punch, it is easy to slide, make troubles to boring.

Authorization Notice No. is the utility model patent of CN200967100Y, disclose Manual pressure hole puncher, it is made up of leverage, drilling rod, drilling rod power-assisted cover, handle and drill bit, it is characterised in that drilling rod power-assisted cover is set to cylindrical, upper end is provided with box thread, and bottom is provided with male thread; This punch tool has the following disadvantages, its one, this punch tool is fixing good not to object when holing, it is easy to slide; Its two, this punch tool is only provided with screw thread, and punch tool is not provided with the edge of a knife, in rotation process could not cutting object very well, so still comparing effort during boring, inconvenient.

Practical novel content

The utility model provides a kind of manual simplified punch tool, the problem solving existing manual punch effort and easily sliding.

The utility model solves the problem by the following technical programs:

A kind of manual simplified punch tool, comprising handle and open tube, the middle part of handle is fixedly connected with one end of open tube, and the open tube the other end is set to the tooth shape mouth of pipe, wherein, the tooth of the described tooth shape mouth of pipe is arcuate serrated, and namely the arc trend of each arcuate serrated is same direction, and the arc-shaped side in this arcuate serrated has the curved edge of tangent plane, vertical edge is the vertical edge of a knife of tangent plane, in punch tool rotation process, object can be cut by curved edge, is conducive to boring; In addition, after life-time service edge of a knife rust, it may also be useful to person is easy to curved edge to sharpen, the more laborsaving convenience of punching is made;The top of arcuate serrated is most advanced and sophisticated, and this tip has fixed action when holing.

Using to be convenient for people to left-handed or the right hand, the arc of the curved edge of the arcuate serrated on the described tooth shape mouth of pipe moves towards in arranging clockwise or counterclockwise, more selects to people.

In order to can make arcuate serrated better cut need boring object and arcuate serrated blunt after can better sharpen, it is preferred that the vertical edge of a knife in arcuate serrated becomes 10 ° of-65 ° of angles with the tangent line of the curved edge in another adjacent arcuate serrated.

Cause the sliding phenomenon of hand to prevent hand in use procedure from perspiring, described handle is provided with rubber coating or other anti-skidding covers, it is also possible to prevent metal handle from getting rusty further, it is to increase the work-ing life of this cork drill.

Advantage of the present utility model and effect be:

1. by the open tube mouth of pipe is provided with arcuate serrated, the arc-shaped side of arcuate serrated is set to the curved edge of tangent plane, and on the one hand, punch tool is in rotation process, and object can be cut by curved edge, is conducive to boring; On the other hand, after life-time service edge of a knife rust, it may also be useful to person is easy to curved edge to sharpen, the more laborsaving convenience of punching is made.

2. the top of arcuate serrated is most advanced and sophisticated, and this tip has fixed action when holing, and makes boring more stable.

3., further, by the curved edge of the arcuate serrated on the tooth shape mouth of pipe is provided with clockwise and counterclockwise two kinds of trends, it is convenient for people to select to move towards clockwise and counterclockwise according to left hand accustomed to using or the right hand.

Accompanying drawing explanation

Fig. 1 is a kind of perspective view implementing mode of the utility model;

Fig. 2 is a kind of two dimensional structure schematic diagram implementing mode of the utility model;

Fig. 3 is the two dimensional structure schematic diagram that another kind of the utility model implements mode.

Number in the figure: 1 handle, 2 open tubes, 3 tips, 4 curved edges, 5 arcuate serrated, the 6 tooth shape mouths of pipe, the 7 vertical edges of a knife.

Embodiment

Below in conjunction with embodiment, the utility model is described in further detail.

In the enforcement mode described in Fig. 1, the manual simplified punch tool of one described in the utility model, comprise handle 1 and open tube 2, handle 1 and open tube 2 all adopt metallic substance or other strong material to make, the radius of open tube 2 is 0.2-5cm, prevent corrosion, at the surface painting last layer paint of handle 1 and open tube 2; The medium position of handle 1 welds with one end of open tube 2, and handle 1 is symmetrical about open tube 2, and handle 1 is provided with rubber coating or other anti-skidding covers.

Open tube 2 the other end is set to the tooth shape mouth of pipe 6, wherein, the tooth of the tooth shape mouth of pipe 6 is arcuate serrated 5, the arc of curved edge (4) moves towards in arranging clockwise or counterclockwise, the number of arcuate serrated 5 is 3-6, the number of arcuate serrated can become big along with the radius of open tube and increase, and user can select the radius size of the open tube oneself needed. Arc-shaped side in arcuate serrated 5 is the curved edge 4 of sharp tangent plane, and vertical edge is the vertical edge of a knife 7 of tangent plane, when holing, object can be cut by curved edge 4, making boring more efficient and convenient, the top of arcuate serrated 5 is most advanced and sophisticated 3, and most advanced and sophisticated 3 have fixed action.

In the enforcement mode described in Fig. 2, Fig. 2 is that arcuate serrated 5 arc-shaped side moves towards two dimensional structure schematic diagram clockwise, wherein, the curved edge 4 of the sharp tangent plane of arcuate serrated 5 moves towards clockwise, when this manual punch rotates clockwise, object is cut by the curved edge 4 of the sharp tangent plane of arcuate serrated 5, accelerates arcuate serrated 5 and enters object, makes boring more laborsaving, convenient.

In the enforcement mode described in Fig. 3, Fig. 3 is that arcuate serrated 5 arc-shaped side moves towards two dimensional structure schematic diagram counterclockwise, wherein, the curved edge 4 of the sharp tangent plane of arcuate serrated 5 moves towards counterclockwise, when this manual punch rotates clockwise, object is cut by the curved edge 4 of the sharp tangent plane of arcuate serrated 5, accelerate arcuate serrated 5 and enter object, make this cork drill can meet the use of different people, people can buy according to the use habit of oneself when buying, the better demand meeting society.

Below the better embodiment that the utility model is created has been carried out concrete explanation, but the utility model is not limited to embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite not running counter to the utility model creative spirit, and these equivalent modification or replacement are all included in the scope of the application.
