Abstract
The utility model relates to a converting device for large and small drill bits, which is characterized by comprising a clip head and a sleeve, wherein the tail end of the sleeve is in a taper shape, and three adjustable screws are uniformly distributed in the middle part of the sleeve. The device is in a form similar to that of an electric drill clamping head, a root of the device can be directly installed on an electric drill, the three adjustable screws are uniformly distributed in the middle part, and the distance of the drill bits can be adjusted according to the sizes of the drill bits to achieve the clamping effect. The device is convenient for the operation of an electric hand drill when a large drill bit is used, the production cost is saved and the potential safety hazard is reduced.
Description
Technical field
The utility model relates to a kind of assembling with big or small drill bit conversion equipment.
Background technology
Existing electric hand drill only is suitable for φ 9mm with interior drill bit, when needs use drill bit greater than φ 9mm, can only take usually: the polishing of drill bit root diameter (RD) is dwindled being applicable to the mode of general electric hand drill, or directly used large-scale electric hand drill.Because the polishing drill bit is not only time-consuming and have certain potential safety hazard, and use large-scale electric drill operation very inconvenient, and need replacing electric drill frequently, in addition for the assembling field, the frequency of using big drill bit still is less, and buying large-scale electric drill has increased an expense that practical value is not high unavoidably again.
The utility model content
Technical problem to be solved in the utility model provides the big or small easily drill bit conversion equipment of a kind of replacing, reduces potential safety hazard, saves production cost.
For solving the problems of the technologies described above, the utility model provides a kind of big or small drill bit conversion equipment, and it is characterized in that: comprise dop, sleeve, barrel end is tapered, uniform three expansion screws of sleeve mid portion.
The utility model form class is similar to the electric drill chuck, and root can directly be installed on the electric drill, and uniform three expansion screws of mid portion can be according to its distance of the size adjustment of drill bit to reach the effect of clamping.Production cost is saved in the operation of electric hand drill during big drill bit easy to use, reduces potential safety hazard.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, the utility model comprises dop 1, sleeve 2, and barrel end is tapered, uniform three expansion screws 3 of sleeve mid portion.
Claims (1)
1. one kind big or small drill bit conversion equipment, it is characterized in that: comprise dop, sleeve, barrel end is tapered, uniform three expansion screws of sleeve mid portion.
