Abstract
The utility model discloses a novel spiral tap mainly comprising a spiral tap head and a tap shank fixedly connected with the spiral tap head, wherein one end of the spiral tap head is also provided with a bit integrated with the spiral tap head; the tail part of the tap shank is connected with a nut through a screw thread arranged on the surface of the tap shank; and the nut is a tetragonal or hexagonal nut. The novel spiral tap is simple in structure, convenient to operate as well as time-saving and labor-saving in operation because the bit is directly arranged at the spiral tap head; and due to the adoption of the design that the detachable hexagonal nut is additionally arranged at the tail part of the tap, the novel spiral tap not only can be matched with a hand-operated spanner tool, but also can be connected with a pneumatic socket tool so as to be wide in application range.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, is a kind of screw tap specifically.
Background technology
At present when the machining screwed hole, at first use drill bit bottoming hole, rear is modal a kind of method with tap tapping because boring and tapping be minute twice independently operation carry out, tend to make bottom outlet and screw tap size not to mate or inharmonious, finally cause screwed hole to tilt or damage; In addition, the regular tap afterbody usually adopts the fixed form of square structure, and is more single, and applicability is not extensive, and fragile.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of can realize simultaneously punching and tapping and the extensive Novel spiral screw tap of the scope of application are provided.
The purpose of this utility model is achieved by the following technical solution: mainly comprise spiral conehead and the taper shank that is connected with it, the first end of described screw conic also is provided with a drill bit, and spiral conehead and drill bit are one-body molded; The afterbody of described taper shank is connected with a nut by being arranged on its surperficial screw thread.
Nut described in the utility model is four jiaos or hex nut.
The beneficial effects of the utility model are: it simple in structure, easy to operate, and drill bit is set directly at the screw tap head, and it is time saving and energy saving to operate; The screw tap afterbody adds the design of dismountable hex nut, can not only cooperate the manual wrench instrument, can also be connected with pneumatic pullover instrument, and the scope of application is extensive.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: as shown in Figure 1, the taper shank 2 that it mainly comprises spiral conehead 1 and is connected with it, described spiral conehead 1 one ends also are provided with a drill bit 3, and spiral conehead 1 is one-body molded with drill bit 3; The afterbody of described taper shank 2 is connected with a nut 5 by being arranged on its surperficial screw thread 4.
Described nut 5 is four jiaos or hex nut.
Embodiment: taper shank mainly adopts rectangular structure, and tailing screw flight partly adopts cylindrical structure, can satisfy general reality and use; When needs during with pneumatic pullover being used, nut can be changed, the outside dimension of nut is variable, according to pullover different size, selects corresponding nut size to get final product.
Certainly, above-mentioned explanation is not limitation of the utility model, and the utility model also is not limited to above-mentioned giving an example; those skilled in the art; in scope of the present utility model, the variation of making, change and add or replace, all should belong to protection domain of the present utility model.
