る。In the conventional driving type anchor, a pin made of a solid material is used as a spreading pin.
It may be slightly conical towards the front end.
The front end edge of the expansion pin presses the expansion segment formed by the longitudinal slit outward and wedges into the bore. Since the outer diameter of the expanding pin corresponds approximately to the diameter of the vertical hole of the expanding sleeve, the end face edge of the expanding pin is tapered from the cylindrical portion of the vertical hole at the time of driving. Immediately after the transition to the abutment against the inner surface of the section. The transition is also provided with a joint for the open pivoting movement of the expansion segment, so that only an extremely short lever arm is available to push the expansion segment open. As a result, a high initial impact energy is required, which may lead to compression or chip scraping on the inner surface of the tapering section of the spreading sleeve. This may impede the complete driving of the expansion pin with a narrow bore, and thus the orderly locking of the driving anchor cannot be achieved.
Also, since a large driving energy is required at the start of the expansion process, the driving anchor itself is also largely displaced toward the bottom of the drilled hole, which causes the end face edge of the driving anchor to move. , It is buried in the bottom of the tapered hole. Therefore, the opening and swiveling operation of the expansion segment becomes more difficult especially in the drilled hole provided with the undercut portion.

囲における固定では固定リスクが高められてしまう。Due to the above-mentioned drawbacks, known implantable anchors often cannot be fully expanded and tidyed in place, even with the application of high impact energy. As a result, the retention coefficient becomes small, and the fixing risk is increased particularly in the fixing in the range where there is a risk of breakage.

る。SUMMARY OF THE INVENTION The object of the present invention is to improve the driving anchors of the type mentioned at the outset, in order to drive the expanding pins into the expanding sleeve, with a clearly reduced driving force. It is an object of the present invention to provide a drive-type anchor that requires only force and that can fully drive the expanding pin.

When the expansion pin is driven in, the portion abuts on the inner surface of the section at a predetermined distance from the transition section from the cylindrical portion of the vertical hole section to the tapered section.

になる区分へ完全に打込むことが可能となる。According to the present invention, the expanding pin is provided at the front end surface of the expanding pin so that the expanding pin is separated from the joint of the expanding segment. It only acts on the inner surface of the tapering section of the expansion sleeve after a certain distance. This results in a favorable lever ratio, which makes it possible to press the expanding segments away from each other only with a significantly reduced driving energy.
The thrust of the expanding pin directed to the bottom of the drilled hole is sufficiently converted into a radial force component. When the expansion segment that has been opened and swung by the front end face edge of the spigot is driven continuously, the original expansion pin is driven until the spigot is attached to the bottom of the drill hole. Since the bottom of the hole is tapered and the spigot partially enters the bottom of the hole, the expanding pin can be driven completely into the tapered section of the vertical hole.

の内面のほぼ真ん中に当接するようになる。Therefore, it is possible to obtain an orderly and sufficiently fixed state of the driving type anchor having a holding coefficient of an appropriate height by using a relatively small driving energy. A particularly advantageous lever ratio is obtained when the diameter of the spigot corresponds approximately to the average diameter of the tapering section and the length of the spigot corresponds to approximately half the length of said section. This causes the end edge of the spigot to abut approximately the center of the inner surface of the tapered section.
