A long hole that rotates in the 0 degree range is provided on the top surface of the support plate, and a large diameter opening with a tapered peripheral surface is formed at both left and right ends inside this long hole, and a tapered portion and a large diameter opening are formed at one end. Insert the screw shaft provided with the convex part and the head into the main opening provided on the upper surface of the lower end of the pillar, pass it through the long hole of the inner support plate, insert the bullet into it, and connect it to the other end. A hurdle with screws attached to it. (2) Insert a column into the ``-shaped'' support plate provided on the leg tube that is fixed on the ground, and make sure that this column is 99 degrees relative to the leg tube.
A long hole that rotates in the 0 degree range is provided on the top surface of the support plate, and a large diameter opening with a tapered peripheral surface is formed at both left and right ends inside this long hole, and a tapered portion and a large diameter opening are formed at one end. A spiral rod with a convex portion and a head is inserted into the main opening provided on the upper surface of the lower end of the pillar, and is also fitted into the long hole of the inner support plate, and an ammunition is inserted therein. A screw is provided at the end, a locking part of the operating shaft is provided inward of the guide tube, a bullet is provided outward, and inserted into the through hole of the guide tube, and an E-shaped retaining ring is inserted into the groove provided at the tip of the operating shaft. The locking portion of the operating shaft is locked in a round tapered recess formed by a plurality of frame plates provided on the side surface of the upper end of the support.
