Abstract
A manual drilling protective sleeve is characterized by the inclusion of an inner sleeve and an outer sleeve, wherein the inner sleeve is provided with internal threads, the outer sleeve and the inner sleeve are in clearance fit with each other, the front end of the outer sleeve is matched with the surface shape of drilling workpiece, and a viewing port is formed on the side surface at the front end of the outer sleeve. The drill bit angle are prevented from being inclined due to the vibration of hands by utilizing the manual drilling protective sleeve, so as to ensure that the axial line of the electric (pneumatic) drill is perpendicular to the workpiece surface, reduce the shaft fluctuation during the drilling process to the utmost extent, meet the assembly requirements of such fastening pieces as bolts, rivets and the like, and ensure the safe and reliable connection.
Description
Technical field
The utility model relates to a kind of boring protection instrument, especially relates to a kind of hand drill protective sleeve.
Background technology
Present now wagon drill hole method, armrest is held electricity (wind) and is bored and finish fully.Because the position that existing car need be holed is uncertain, the situation that all may occur holing in positions such as level, vertical, arc surfaces, and hand-held electricity (wind) bores the perpendicularity of uncontrollable main shaft, so occurring the axis in hole easily tilts, not vertical with plate face situation also just can't satisfy the matching requirements of securing members such as bolt, rivet.
The utility model content
The purpose of this utility model provides a kind of boring protective sleeve, and this protective sleeve can be realized vertical with workpiece at an arbitrary position, thereby gets out the eyelet of vertical surface of the work, satisfies matching requirements.
For achieving the above object, the utility model provides a kind of hand drill protective sleeve, it is characterized in that: comprise interior cover, overcoat; interior cover has internal thread; overcoat cooperates with interior cover gap, and the overcoat front end matches with the surface configuration of boring workpiece, and observation panel is opened in the side of overcoat front end.
The utility model has avoided causing owing to the vibration of hand the inclination of drill bit angle effectively, the axis that guarantees electricity (wind) brill constantly is vertical with surface of the work, the axle that reduces to greatest extent in the boring procedure is beated, and satisfies the matching requirements of securing members such as bolt, rivet, guarantees to connect safe and reliable.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
With reference to accompanying drawing, form the column type protective device by overcoat 1, interior cover 2, interior cover has internal thread, and overcoat cooperates with interior cover gap, and interior Analysis of Nested Design becomes female thread structure, can be fixed on the drillstock of electricity (wind) brill by screw thread; The internal diameter of overcoat is worked into the size with interior cover crest clearance precision-fit, front end is processed according to the surface configuration of boring workpiece, is evagination as the drilling part surface, and the front end of overcoat just is processed into indent, simultaneously open observation panel 3, to make things convenient for the centering of bore position in the side of overcoat front end.
During work, one holds electricity (wind) bores, and one holds the overcoat of protective sleeve, and it is tight that overcoat front end and surface of the work are pasted, and drill bit is done the rectilinear motion of vertical surface of the work under the guiding of interior cover, can finish the existing wagon drill hole of any position.
Claims (1)
1. hand drill protective sleeve, it is characterized in that: comprise interior cover, overcoat, interior cover has internal thread, and overcoat cooperates with interior cover gap, and the overcoat front end matches with the surface configuration of boring workpiece, and observation panel is opened in the side of overcoat front end.
