If the upper surface 30 of the lower end of the cylindrical body 23 without the longitudinal grooves 26 of the pushing body is positioned above each of the convex parts 19 by moving the collar 18 from above each convex part 19,
The upper surfaces 30 come into contact with the respective convex portions 19 to lock the pusher.

As described above, in the present invention, a notch is provided on the circumferential surface of the flange at the lower end of the upper lid guide tube, and the lower end of the vertical rib that can be inserted into the notch on the cylindrical peripheral wall of the pusher is connected to the lower surface of the flange. Since it is molded flush, it is possible to reliably prevent the pusher from coming off even if it is misused.

That is, even if the operating knob is operated while lowering the pushing body at the position where the operating knob is extended, the vertical rib will not descend and separate from the clamping part while being clamped by the clamping part of the operating knob. This completely prevents the operation knob from moving.

In addition, both the upper cover and the pusher have a simple structure and can be locked with just an operating knob, so the number of parts is extremely small. Assembling is very simple because the assembly is accomplished by simply inserting the other seats into the notch and into the recesses of the collar of the guide tube from above, turning the pusher, and aligning the vertical ribs within the clamping portion.
