By using above-mentioned technical proposal, the technique effect that the utility model is reached is：This product is drilled by improving
The structure of toothed portion, enabling to the work of perforate becomes extremely smooth, and is not in that drilling tooth breaks either perforate
The device directly stuck phenomenon in hole, has effectively saved the waste of the manufacture material of this product, and improve perforate product
Yields.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is dimensional structure diagram of the present utility model.
Fig. 2 is free of drill bit, the cross-sectional view of spring to be of the present utility model.
Embodiment
Reference picture 1,2, is a kind of hole making drill disclosed in the utility model, including body, and the upper end of body is bare terminal end 12,
Inward-facing offer in the lower end of body is provided with collared hole 14, collared hole 14 in the middle part of cavity 13, the bottom of chamber of cavity 13
The drill bit 15 that head is stretched out outside cavity is installed, spring 16 is arranged with drill bit 15, collared hole 14 is towards the hole outside cavity
Provided with neck 17 is expanded at mouthful, spring 16 is located at the end in cavity and is fixed on expansion neck 17.Wherein, body is by drilling tooth
Fixing body 10, drill bit fixing body 11 and the part of bare terminal end 12 3 composition, the external diameter of drilling tooth fixing body 10 are installed more than drill bit
