Description
Technical field:
The utility model relates to the safety means that a kind of structure is improved, more specifically to a kind of expansive bit protective cover.
Background technology:
Drill bit goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.Head goes out through hole or blind hole in order to drilling on solid material, and can to the cutter of existing hole reaming.Conventional drill bit mainly contains fluted drill, chit drill, centre drill, depth drill and cylindrical drill.With drill bit when boring, can be flown out some bits, and bits easily fly into the positions such as the eyes of people, bring injury to human body, if design a kind of device that can prevent these flying chips from flying out just can address this problem, so it is very useful for designing a kind of expansive bit protective cover.
Utility model content:
The purpose of this utility model is exactly for the deficiencies in the prior art, and provides the safety means that a kind of structure is improved.It is simple that the utility model has structure; easy to use; by the retainer plate of fixing protective sleeve upper edge, protective cover is fixed on above drill bit; movable protective sleeve is wrapped in around drill bit; when drill bit down bores, movable protective sleeve is extruded toward rising, and spring is compressed; the bits that protection drill bit gets out do not splash out, the advantage of the personal safety of protection operator.
Technology solution of the present utility model is as follows:
The safety means that a kind of structure is improved; comprise fixing protective sleeve and movable protective sleeve; a circle in-flanges is provided with bottom described fixing protective sleeve; movable protective sleeve top is provided with a circle flanging; flanging is buckled on in-flanges; fixing protective sleeve top is provided with flange under a circle, and movable protective sleeve top is provided with a circle upper overturning, and upper overturning and lower flange are compressed with a coil spring.
In technique scheme, described fixing protective sleeve upper edge is fixed with a retainer plate, retainer plate is evenly equipped with four trip bolts.
The beneficial effects of the utility model are:
The utility model structure is simple; easy to use; by the retainer plate of fixing protective sleeve upper edge, protective cover is fixed on above drill bit; movable protective sleeve is wrapped in around drill bit; when drill bit down bores, movable protective sleeve is extruded toward rising, and spring is compressed; the bits that protection drill bit gets out do not splash out, the personal safety of protection operator.
Accompanying drawing illustrates:
Fig. 1 is the utility model (being contained on drill bit) structural representation;
Fig. 2 is the A-A structural representation of Fig. 1.
In figure: 10, fixing protective sleeve; 101, retainer plate; 1011, trip bolt; 102, lower flange; 103, in-flanges; 104, spring; 20, movable protective sleeve; 201, flanging.
