される、等々の欠点がある。C. Problems with the prior art However, when drilling a blind hole h in the column C at an angle of approximately 45 degrees, as shown in FIG. A drill d equipped with a guide pin P is driven to drill a hole using an electric tool D. However, since the drilling angle is obliquely inclined to the surface of the column C, the drill d comes into contact with the surface, and the part of the claw of the drill ( It is fine while the blade (acting for cutting) is entering, but as it progresses further and reaches the blade part (acting for cutting), the rotation of the power tool D becomes extremely tight, as if momentarily restraining it. If the tool is subjected to a large reverse torque, the tool being held may be thrown out of both hands, resulting in injury, or even if the tool is able to withstand excessive torque and is held, due to the characteristics of Drill d, the drilling progress speed will rapidly increase. , instantly penetrates to the bottom of the
There are drawbacks, such as the fact that instead of a blind hole, a through hole corresponding to the diameter of the drill is drilled, which necessitates the rebuilding of the pillar C.

的を充分達成し得る優れた効果を奏する。 However, drilling was started, and as mentioned above, the blade of the drill d began to cut into the pillar C, and the power tool D
Even if it is subjected to instantaneous reverse torque, the lever L is restrained in contact with the lower surface of the column C at its lower bent portion, and the upper part is held by the grip g, so that the worker cannot The drilling work can be continued without receiving any reverse torque, and even if the drill D's blade is pulled strongly toward the column, it can be done simply by hand as in the past. Unlike the case where the power tool D is gripped only by force, which is unstable and has a weak holding force, the lower part is restrained by the lower surface of the column C at the bent part, and the upper part is gripped with one hand. Therefore, excessive drilling can be easily prevented simply by gripping the grip g so as to resist the retraction force.Furthermore, during this operation, the ram L
Even if the upper surface of the column C approaches and is displaced, since the sleeve T is rotatably fitted to the bent part of the lever, the lower surface of the column C can be moved by the amount of displacement, and the worker will not be able to avoid abnormalities. This invention has excellent effects that can fully achieve the purpose of the present invention, such as making it possible to complete the ideal drilling operation extremely easily without requiring excessive force.
