In state-they are placed next to each other. In this state, the blocking member 80 and the reaction force member 80 'are weakly touched or simply abutted by the ends 92, 92' of the springs 90, 90 '.

Hereinafter, the operation relationship of the fastening unit 60 according to the present invention with reference to FIGS.

As described above, the blocking member 80 is a guide groove 74 of the fixing bracket 70 with one side of the body 81 weakly touched or simply abutted by the end 92 of the spring 90. Is located across. In the inoperative state, the body 81 of the blocking member 80 is in a position to close the groove 73-more specifically, the engaging groove 75 (FIG. 7 state). In this state, a force is applied to the blocking member 80 to press the spring 90. More specifically, the end portion 92 of the spring holding the blocking member 80 is centered around the screw 97 as a fixing member. When the shaft is rotated in the direction of the arrow in FIG. 7, the groove 73 is opened. When the force is removed, the blocking member 80 is returned to its original position by the restoring force of the spring 90. The groove 75 is closed again. Therefore, the force is applied to the blocking member 80 to axially rotate to seat the lower end of the connecting rod 23 of the slide unit 20 (see FIG. 3) in the coupling groove 75 while the groove 73 is opened. Remove or simply push the connecting rod 23 in the groove 75 direction while the blocking member 80 is axially rotated while the connecting rod 23 is positioned in the groove 75 while the blocking member 80 is again spring ( Since the groove 73 is closed by returning to the original position by 90, the slide unit 20 is coupled to the fastening unit 60 via the connecting rod 23 (FIG. 8 state). On the other hand, in this state, the reaction force member 80 'is pushed by the connecting rod 23, and is in the state of being axially rotated while pressing the spring 90'. Now, in order to separate the connecting rod 23 from the groove 75, the groove 73 may be opened by axially rotating the blocking member 80 (FIG. 9 state). In this state, as described above, since the reaction force member 80 'is axially rotated while pressing the spring 90', the reaction force member 80 'is returned to its original position by the force of the spring 90'. Axial rotation (arrow direction) will exert a force to push the connecting rod 23 out of the groove 75. Therefore, the connecting rod 23 can be easily separated from the groove 75. On the other hand, the extension portion 83 of the blocking member 80 functions as a pressurizing portion that makes it easier to apply a force when applying a force to axially rotate the blocking member 80.

When in the non-operational position of the blocking member 80 and the reaction force member 80 'as shown in FIG. 7, these members 80, 80' press the springs 90, 90 'at this position. The shaft rotation in the opposite direction is limited by the screws 97 and 97 'which are fixing members. As such, the screws 97 and 97 'serving as the fixing members not only serve to fix the coil portions 91 and 91' of the spring to the fixing bracket 70, but also the members 80 and 80 'are inoperative. It also serves as a stopper for limiting the rotation of the spring in the opposite direction to the direction in which the spring is pressed.

In the above described the present invention with reference to the accompanying drawings, those skilled in the art will recognize that various modifications are possible. For example, a straight blocking member may be used without the extension 83 serving as the above-mentioned pressing part, and a rivet instead of a screw may be used as the fixing member. In addition, the fastening unit in which the grooves and the members are positioned in the mirror symmetry as in the embodiment shown in FIG. 4 may be manufactured.
