One end of the spring 17 engaged with the spring 17 is engaged with the main body 2 and the other end is engaged with the opener 11 so that the opener 11 always rotates toward the main body 2. The surface that contacts the outside of the main body 2 bulges inward to protrude the locking part 18, and the locking part through hole 19 passes through the sliding groove 13 at the part where the locking part 18 contacts.
is bored so that the locking part 18 of the opener 11 can protrude into the sliding groove 13, and resists the elasticity of the bullet 15, which is equipped with a sliding member 14 that can slide inside the sliding groove 13. At the position where the opener 11 slides and locks with the stopper 16', it engages with an engaging groove 20 drilled at a position where the protruding portion of the locking portion 18 of the opener 11, which is a part of the sliding surface, makes contact. Then, the opener 11 moves the spring 1 around the shaft 12.
Unless the sliding member 14 rotates against the elastic force of the bullet 7, the sliding member 14 is formed so as to remain immobile against the bullet 15.

By slightly rotating the sliding rotation with the guide plate 3, the center pointing distance of the Cheza-7 can be slightly changed.

とによって微少の調整をも行える。11j In the fine adjustment mechanism 27, both ends of the movable range of the adjustment piece 30, which moves forward and backward by applying rotational motion to the operating shaft 29, are set in the radial direction of the cam play 1-3, and the ends of the movable range of the adjustment piece 30 are set in the radial direction of the starting end X of the movable range. If we connect the radial direction of the terminal end y with the concentric circular line 2, we get the working distance l, and during this adjustment, the diagonal line The movable distance of the adjustment piece 30 becomes longer in proportion to the angle 0, and therefore the working distance 1 also becomes longer.In order to increase the accuracy of fine adjustment, the angle of the acute angle 0 can be increased to make fine adjustments. I can do it.

This movement is slid within the cam plate connecting piece 22 o JIR 23 and only the action in the two circular directions is transmitted to the cam plate h connecting piece 22 (1, this action is transferred to the cam plate h connecting piece 22 Then slide the sliding member 14 onto the main body 2 with a
The cam tz- 3 acts on the main body 2 by the amount of rotation 17, and the chaser 7 moves within the chaser sliding groove 6 in accordance with the amount of rotation.

効果を有するも尚である。The movement in and out of the conventional chaser in the radial direction is exclusively done by cam play!・Only sliding rotation is performed between the chaser and the main body, so it is very difficult to make minute movements in and out of the chaser, and it is a technology that is almost impossible to accurately achieve the desired minute movement under that operating state. In this invention, the desired degree of rotation a of the cam plate t-3 is achieved by movement by rotation of the adjustment piece 30, which is several ten times as large as the operation @29, and the movement means is actuated by a screw movement. Moreover, it has the effect of preventing occurrence of phenomena due to deviation from desired operation during the operation of the die and the rad.
