の取付角度を変更する技術思想は有していない。The former mounting mechanism merely aims to improve the reliability at the time of mounting, and does not consider the operability related to the change of the mounting angle of the side handle at all. Therefore, here, the engagement depth of the concave and convex portions is set deep in order to obtain a high coupling force, and in order to eliminate the interference between the two and make the side handle rotatable, it is necessary to loosen the wing bolt considerably to remove the side handle. It is necessary to greatly increase the inner diameter of the cylindrical portion of the above. Therefore, the usability related to the angle change is very poor. In addition, since separate components are provided for each of the functions of the rotation stopper and the stopper, the shape becomes complicated and the manufacturing cost increases. on the other hand,
The latter is configured only for the purpose of facilitating the position adjustment relating to the axial movement of the handle and increasing the reliability in the positioning state, and changes the mounting angle of the handle in the circumferential direction. I do not have a technical idea.

A side handle mounting mechanism for fixing the two by inserting a cylindrical insertion portion of the side handle whose inner diameter can be adjusted into the mounting portion of the side handle on the main body side, wherein the outer periphery of the mounting portion on the main body side is fixed. In the meantime, a plurality of convex portions are provided at predetermined intervals in the circumferential direction, while a plurality of fitting convex portions corresponding to the concave portions formed between the respective convex portions are formed on the inner peripheral surface of the insertion portion on the side handle side in the circumferential direction. Provided along the outer periphery of the mounting portion on the main body side,
When the side handle is attached, a stopper for restricting the advance of the fitting convex portion is provided so as to protrude forward between at least two of the convex portions, and furthermore, both side edges of each convex portion in the main body axial direction and the side thereof. To both side edges of each fitting projection corresponding to the edge,
An inclined surface which inclines outward in the circumferential direction of the attachment portion or the insertion portion is formed, respectively.

動させることができる。When the insertion portion of the side handle is inserted into the side handle mounting portion of the main body, the fitting projection on the inner peripheral surface of the insertion portion is fitted into the recess between the projections of the mounting portion, thereby preventing the side handle from rotating. The stopper provided forward between the protrusions of the mounting portion regulates the forward movement of the fitting protrusion on the side handle side, and prevents the side handle from coming off in the axial direction. Also, when changing the mounting angle of the side handle once fixed, if the inner diameter of the insertion part is slightly increased, the protrusions on the side handle side and the fitting protrusion on the main body side will interfere with each other due to the inclined surfaces provided on both side edges. Is reduced, so that the convex portion can easily get over the fitting convex portion, and can be rotated with the side handle attached to the main body.

FIG. 2 is a front view of the gear housing 1. The protrusions 4, 4,... And the stoppers 6, which are provided around the mounting portion 3, have both side surfaces inclined outward in the circumferential direction of the mounting portion 3. Slope 4
a, 4a, 6a, and 6a, and each inclined surface has an angle θ 1 of 30 degrees as shown in FIG. Similarly, FIG. 4 is a cross-sectional view of the side handle 2. On both side surfaces of the fitting projection 15, inclined surfaces 15 a, 15 a which are respectively inclined outward in the circumferential direction of the insertion portion 7 are formed. 5, the angle θ 2 is 60 degrees as shown in FIG. Since the projections 4 and the fitting projections 15 have inclined surfaces on both sides, when the fitting projections 15 of the side handle 2 and the projections 4 of the gear housing 1 are fitted to each other, the gear housing 1 When the mounting angle of the side handle 2 is changed after the side handle 2 is mounted on the gear housing 1, the inner diameter of the side handle 2 is slightly increased. It is possible to rotate the side handle 2 with the side handle 2 fitted, and it is easy to change the mounting angle of the side handle. In particular, it is easier to rotate the angle of the inclined surfaces if the inclination of the rotating side (side handle 2 side) is gentler than that of the main body side (gear housing 1 side). It is a preferable example that the angle is about 30 degrees and the angle of the fitting projection 15 side is about 60 degrees.

2 is loosened so that the inner diameter of the insertion portion 7 is enlarged, and the inner diameter of the fitting projection 15 is made larger than the outer diameter of the stopper 6 on the gear housing 1 side. After rotating to an arbitrary angle, the wing bolt 12
Is tightened, the fixing bases 10, 11 and the split groove 7b are narrowed, and the fitting projections 15, 15 of the side handle 2 are
And the side handle 2 is fixed at that position (FIG. 6). At this time, the projection 4 and the fitting projection 15
Is a detent that prevents the rotation of the side handle 2, and the stopper 6 is a stopper that restricts the advancement of the fitting projections 15, 15 in the recesses 5, 5. Even if an external force acts on the side handle 2, the side handle 2 is securely fixed (FIG. 7). In particular, two stoppers 6, 6
By simply arranging 6, regardless of the angle of the side handle 2, the fitting projection 15 can be easily prevented from coming off. Therefore,
Even if the components relating to the rotation stopper and the stopper are separately provided, a rational configuration with less processing and molding can be obtained, and the cost increase can be minimized. Conversely, when removing the side handle, loosen the wing bolt 12 and insert the
Can be removed in the direction of the tip of the hammer drill. However, in this embodiment, since the thickness of the projection 4, the fitting projection 15, and the stopper 6 is small,
Regardless of whether the side handle is attached or detached, the change of the inner diameter of the insertion portion 7 by the wing bolt 12 is small, and the labor for attaching and detaching is reduced. Also side handle 2
Is fixed once, the fitting angle between the fitting projections 15 and the projections 4 is weakened by only slightly loosening the wing bolts 12, and the inclined surfaces 4a, 4a, 15a, 15a of the two.
Thus, the rotation of the side handle 2 is facilitated as described above, so that the mounting angle can be easily changed without loosening the wing bolt 12 to the maximum or removing the side handle 2 one by one. In particular, in this embodiment, the side handle is made of synthetic resin, and the side handle itself has elasticity, so that the degree of freedom is generated on the side handle side to reduce the resistance to the convex portion and the stopper on the gear housing side. In addition, the attachment / detachment and rotation operations can be performed more smoothly.

It is possible to easily change the mounting angle. In addition, by arranging at least two stoppers in front of the protrusions for stopping rotation, a reasonable structure can be easily obtained in which the stopper function is easily obtained, and the components relating to the stopper and the stopper are separately provided. However, less processing and molding is required, and cost increase can be minimized.
