Abstract

The utility model relates to a manual screw tap which is provided with a cutting part, a conical part and a conical tail, wherein the cutting part, the conical part and the conical tail are integrally formed, and a guide column is arranged at the front end of the cutting part. The manual screw tap has the advantages of increasing manual tapping efficiency, lowering labor intensity of workers, and increasing working efficiency and workpiece quality.

Description

Hand tap
Technical field
The utility model relates to a kind of Hand tap.
Background technology
Screw tap comes the screw thread in the machining hole by hand, to build processing industry method commonly used, this screw tap is cylindricality, when tapping, Hand tap is difficult for the incision thread Pilot hole, and is difficult to guarantee that the tapping direction is identical with the thread Pilot hole direction, often cause thus the tapping difficulty, affect workpiece quality, even cause screw tap to twist off, user's experience is had relatively high expectations; Need tap wrench when using set tap, the functional limitation of tap wrench is larger, is unfavorable for increasing work efficiency.
The utility model content
The technical problems to be solved in the utility model is: overcome the deficiency in the prior art, a kind of high efficiency is provided, the Hand tap that workpiece quality is high.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of Hand tap, have cutting portion, tapering and cone tail, and described cutting portion, tapering and cone tail are formed in one, and the front end of cutting portion is provided with lead.
Further, the screw on the described cutting portion extends to the outer surface of lead vertically.
Further, the cross section of described cone tail is regular hexagon.
The beneficial effects of the utility model are: the utility model improves the efficient of hand tapping, has reduced labourer's labour intensity, increases work efficiency and workpiece quality.
Description of drawings
Below in conjunction with drawings and embodiments the utility model is further specified.
Fig. 1 is structural representation of the present utility model.
1. cutting portions among the figure, 2. tapering, 3. cone tail, 4. lead.
The specific embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, so it only shows the formation relevant with the utility model.
A kind of Hand tap as shown in Figure 1, have cutting portion 1, tapering 2 and cone tail 3, cutting portion 1, tapering 2 and cone tail 3 are formed in one, and the front end of cutting portion 1 is provided with lead 4, screw on the cutting portion 1 extends to the outer surface of lead 4 vertically, and the cross section of cone tail 3 is regular hexagon.
Above-mentioned embodiment only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of doing according to the utility model Spirit Essence change or modify, and all should be encompassed in the protection domain of the present utility model.
