Abstract
An auxiliary guide device of a handheld drill gun comprises a guide sleeve and a fixed sleeve which is installed on the handheld drill gun, the guide sleeve is in an annular shape provided with a notch, guide strips are installed on the inner wall of the guide sleeve along the axial direction of the guide sleeve, and guide sliding grooves matched with the guide strips are formed in the outer wall of the fixed sleeve. Three anti-inclination supporting legs are installed on the outer wall of the guide sleeve, each anti-inclination supporting leg is composed of a supporting leg drivepipe and a supporting leg body, one end of each supporting leg drivepipe is fixedly connected with the guide sleeve, the other end of each supporting leg drivepipe is provided with an internal thread, and each supporting leg body is connected with each supporting leg drivepipe through an external thread which is circumferentially installed on each supporting leg body. During hole-drilling operation, fixation of the guide sleeve is kept under the action of supporting of the anti-inclination supporting legs, and the axial direction of the guide sleeve faces to the hole-drilling direction all the time. The handheld drill gun faces to the hole-drilling direction all the time under the action of guiding of the guide sleeve and the fixed sleeve, the hole-drilling direction is kept to be unchanged, and inclination is prevented. The lengths of the anti-inclination supporting legs are adjusted through rotation of the supporting leg bodies, the orientation of the guide sleeve is adjusted, and therefore requirements of hole-drilling in different angles are satisfied.
Description
Technical field
The utility model relates to a kind of hand held electric drill, and specifically a kind of hand-held bores the auxiliary guide of rifle.
Background technology
Hand held electric drill is people at the instrument of producing, often can using in the life, such as on the wall or bore installing hole etc. on the equipment.Because this boring bar tool relies on hand-held operation, in use often can run into because hand-held shakiness causes the situation of hole scattering.In case the boring deflection, the lighter can make drill bit stuck, can cause drill rod breaking, cause damage of equipment when serious.Therefore, the people for often not using hand held electric drill is difficult to finish boring work.
The utility model content
Technical problem to be solved in the utility model provides the auxiliary guide that a kind of hand-held bores rifle, can play the guiding operation when boring, places hole scattering.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be: a kind of hand-held bores the auxiliary guide of rifle, comprise fairlead and the fixed cover that is arranged on the hand drill, fairlead is for being with ring-type jaggy, be axially arranged with gib block along it on the inwall of fairlead, outer wall at fixed cover is provided with the guide chute that matches with gib block, be provided with three anti-bias supporting legs at the fairlead outer wall, anti-bias supporting leg is comprised of supporting leg sleeve pipe and leg, one end of supporting leg sleeve pipe is fixedly connected with fairlead, the other end is provided with internal thread, and leg is connected with the supporting leg sleeve pipe by the external screw thread that its circumference arranges.
The axial angle of described anti-bias supporting leg and fairlead is greater than 45 °.
The beneficial effects of the utility model are: during bore operation, rely on the supporting role of anti-bias supporting leg to make fairlead keep fixing, and its axially all the time towards with boring direction.Guide effect by fairlead and fixed cover makes hand drill all the time towards boring direction, keeps boring direction constant, prevents deflection.Adjust the length of anti-bias supporting leg by the rotation leg, with adjust fairlead towards, thereby the boring that realizes different angles needs.

The specific embodiment
As shown in the figure, a kind of hand-held bores the auxiliary guide of rifle, comprise fairlead 2 and the fixed cover 3 that is arranged on the hand drill 1, fairlead 2 is for being with ring-type jaggy, be axially arranged with gib block 201 along it on the inwall of fairlead 2, outer wall at fixed cover 3 is provided with the guide chute 301 that matches with gib block 201, be provided with three anti-bias supporting legs 4 at fairlead 2 outer walls, anti-bias supporting leg 4 is comprised of supporting leg sleeve pipe 401 and leg 402, one end of supporting leg sleeve pipe 401 is fixedly connected with fairlead 2, the other end is provided with internal thread, and leg 402 is connected with supporting leg sleeve pipe 401 by the external screw thread that its circumference arranges.
The axial angle of described anti-bias supporting leg 4 and fairlead 2 is greater than 45 °.
During bore operation, rely on the supporting role of anti-bias supporting leg 4 to make fairlead 2 keep fixing, and make its axially all the time towards with boring direction.Guide effect by fairlead 2 and fixed cover 3 makes hand drill all the time towards boring direction, keeps boring direction constant, prevents deflection.Adjust the length of anti-bias supporting leg by the rotation leg, with adjust fairlead towards, thereby the boring that realizes different angles needs.
