Abstract

The utility model discloses a single-speed angular drilling tool pertaining the art field of drilling tool, which comprises a shell and a main shaft, the main shaft drills through the shell, a drilling clamps is fixed coaxially on the end of the exserted part of the main shaft, a main shaft sleeve is fixed in the shell, the main shaft is positioned in main shaft sleeve, a input shaft sleeve is arranged vertically to the main shaft sleeve in the shell, the input shaft is arranged in the input shaft sleeve, meshed bevel gears are fixed at the ends of the input shaft and the main shaft inside of the shell. Connecting the input shaft with an electrical motor to operate the utility model, switching on the motor drives the input shaft rotating, the torque is transferred to the main shaft by the bevel gear, consequently drives the drilling clamp rotating and implement the drilling process, the utility model applied the vertical arrangement of the input shaft and the main shaft, which greatly decreases the height in the direction of the main shaft, the electrical motor diameter size interferes the drilling operation less which easily facilitates the drilling process in internal edge of corner, height-restricted areas, the utility model is especially suitable for the processing of holes.

Description

Single speed angle drilling tool

Technical field

The utility model relates to a kind of electric tool, particularly a kind of drilling tool.

Background technology

In the prior art, a kind of hand-held drilling tool is arranged, comprise the main shaft that links to each other with motor output shaft, motor is arranged in the housing that can grip, and stretches out the outer end of housing on the main shaft and is coaxially installed with drilling attachment; This drilling tool in use, hand-held operation because motor and be clamped in the coaxial setting of drill bit on the drilling attachment, the whole height that makes drilling tool is than higher, the diameter of motor is big, is not easy in the inboard, corner, height-limited place carries out drilling operation.

The utility model content

The purpose of this utility model provides a kind of single speed angle drilling tool, make its can be in the inboard, corner, height-limited place carries out drilling operation easily.

The purpose of this utility model is achieved in that single speed angle drilling tool, comprise housing and main shaft, main shaft passes housing, main shaft stretches out housing outer end and main shaft and is coaxially installed with drilling attachment, be fixed with collar bush in the housing, main shaft is installed in the collar bush, also is provided with the input axle sleeve with the perpendicular setting of collar bush in the housing, be set with power shaft in the input axle sleeve, the awl gear that is meshed is established in the end that is positioned at housing of power shaft and main shaft.

During the utility model work, power shaft is connected with motor, and during machine operation, power shaft rotates, through the awl gear moment of torsion is passed to main shaft, and then drive the drilling attachment rotation, and the drill bit that is clamped on the drilling attachment is attacked, realize drilling operation, the utility model makes the setting that intersects vertically of power shaft and main shaft, height on the major axes orientation is reduced greatly, and the diameter of motor is little to boring influence, make its can be in the inboard, corner, height-limited place carries out drilling operation easily.The utility model is specially adapted to the processing in hole.

For conveniently gripping and being convenient to when attacking firmly, described hull outside is fixed with the gripping handle perpendicular to main shaft.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is the left view of Fig. 1;

Wherein, 1 collar bush, 2 main shafts, 3 drilling attachments, 4 power shafts, 5 input axle sleeves, 6 awl gears, 7 housings, 8 gripping handles.

The specific embodiment

As figure, single speed angle drilling tool, comprise housing 7 and main shaft 2, main shaft 2 passes housing 7, and main shaft 2 stretches out housing 7 outer end and main shafts and is coaxially installed with drilling attachment 3, is fixed with collar bush 1 in the housing 7, main shaft 2 is installed in the collar bush 1, also be provided with the input axle sleeve 5 with collar bush 1 perpendicular setting in the housing 7, be set with power shaft 4 in the input axle sleeve 5, the awl gear 6 that is meshed is established in the end that is positioned at housing of power shaft 4 and main shaft 2; Housing 7 outsides are fixed with the gripping handle 8 perpendicular to main shaft.

Claims

1, single speed angle drilling tool, comprise housing and main shaft, main shaft passes housing, main shaft stretches out housing outer end and main shaft and is coaxially installed with drilling attachment, it is characterized in that: be fixed with collar bush in the housing, main shaft is installed in the collar bush, also is provided with the input axle sleeve with the perpendicular setting of collar bush in the housing, be set with power shaft in the input axle sleeve, the awl gear that is meshed is established in the end that is positioned at housing of power shaft and main shaft.
