Claims

[Claims for Utility Model Registration] (1) A vibratory doweling machine including a drive rod driven by a vibration source and a head attached to the tip of the rod, wherein the head is A cylindrical inner diameter hole, an end wall closing one end of the inner diameter hole, a boss projecting outward in the axial direction from the outer surface of the end wall, and a boss extending axially through the boss and the end wall. A dowel retaining rod is slidably mounted within the through hole, the rod having an enlarged portion at its inner end, the enlarged portion extending from the end wall of the head. The length of the dowel retaining rod has a portion that projects outwardly from the boss when the enlarged portion and the inner surface of the head end wall are engaged. This protruding portion of the dowel holding rod has a diameter that allows the dowel to be held on its outer circumferential surface, and is further provided with temporary fixing means for temporarily fixing the dowel onto this protruding rod portion. , further comprising spring means between the enlarged portion of the dowel retaining rod and the drive rod, the spring means biasing the dowel retaining rod axially outwardly. Dowel machine. (2) The dowel holding rod includes an inner diameter hole extending in the axial direction at the outer end thereof, and a side slot formed in the side wall of the dowel holding rod so as to communicate with the inner diameter hole, and the temporary fixing means is approximately It is a U-shaped elastic wire, and has a curved engagement part bent so that one leg of the U shape protrudes outward, and this wire is closed into the inner diameter hole of the outer end of the protrusion, with the end first. 2. The dowel holding rod according to claim 1, wherein when the dowel holding rod is inserted, the curved engaging portion protrudes from the slot and engages with a dowel attached to the tip of the dowel holding rod to temporarily fix the dowel on the protrusion. Dowel machine. (3) Claim 1 characterized in that the end of the protrusion engages with the dowel and temporarily fastens the dowel using negative pressure.
Doweling machine as described.
