Then, when the pressing is stopped, the sleeve tries to return to the original shape, so that the sleeve is firmly locked to the tip portion of the tool. At this time, the insertion depth of the tool into the sleeve can be defined by bringing the tip of the tool into contact with the tongue piece in the sleeve. Also,
Since the sleeve is elliptical, the tool diameter whose tip can be protected by this tool cap should be not less than the minor diameter of the ellipse and not more than the diameter when deformed into a circle. Of tools. Further, the sleeve has a relatively thick wall at both ends with a long diameter and a relatively thin wall at both ends with a short diameter, so that the sleeve can be easily deformed into a circular shape.

The sleeve 3 is attached to the tip of a tool such as a drill in a state in which the sleeve 3 is deformed into a substantially circular shape by pressing both ends of the long diameter portion with fingers. When the pressing is stopped, the sleeve 3 attempts to return to the original shape, so that the sleeve 3 is firmly locked to the tip of the tool. At this time, the insertion depth of the tool into the sleeve 3 can be regulated by bringing the tip of the tool into contact with the tongue piece 5 in the sleeve 3.
Also, since the sleeve 3 is oval, this tool cap 1
The tool diameter that can protect the tip by the tool should be not less than the minor diameter of the ellipse and not more than the diameter when deformed into a circle, and can be applied to tools of various diameters. it can. Further, the sleeve 3 has a relatively large thickness at both ends A of the major axis, and both ends B at the minor axis.
Is relatively thin, so that it can be easily transformed into a circle.
