A penetrating shaft and a cam 50b rotating around the shaft are arranged, and the cam 50b is rotated in conjunction with the rotation of the tightening lever 32. The convex portion of the cam 50b rides on the convex portion of the cam 50a. By pressing the convex portion, the width of the slit hole 40b is changed. The cam 50b is configured not to move in the longitudinal direction of the shaft. Further, by adjusting the positions and heights of the protrusions between the cams 50a and 50b, the slit width can be reduced or restored, and the slit width can be appropriately reduced. However, the mechanism for reducing the slit width is not limited to that described above, and any mechanism may be used as long as the slit width can be changed according to the movement of the operation handle 30.

  Moreover, in order to maintain the connection state of the male connection parts 11, 12, 13, and 14 and the female connection parts 21, 22, 23, and 24, in the connection structure 20 for capsule cartridges concerning this embodiment, FIG. As shown by 4, a mechanism capable of holding the final arrival position of the operation handle 30 is employed. That is, as shown in FIG. 4, the operation handle 30 at the final arrival position is movable in the front-rear direction (the direction from the diagonally left front side to the diagonally rearward side of the paper), and the operation handle 30 at the final arrival position. Is moved rearward (backward direction in the drawing), so that the tip of the operation handle 30 is inserted into a holding block hole 55 as a handle operation restricting means. Due to the action of the holding block hole 55, the operation handle 30 cannot move in the vertical direction, and the final arrival position is held. In order to release this state, the operation handle 30 at the final position may be moved from the rear to the front, and the tip of the operation handle 30 can be easily removed from the holding block hole 55 by such operation. 30 can move up and down again.

  As mentioned above, although preferred embodiment of this invention was described, the technical scope of this invention is not limited to the range as described in the said embodiment. Various modifications or improvements can be added to the embodiment.
