Until it disappears (until the inner surface of the upper end of the inner cylinder 20 comes into contact with the shaft rod portion 19), the central portion of the suction disc body 1 is further pressed, and the outer peripheral edge portion 2 is separated from the wall surface A or the like and the suction disc body is formed. 1 is in a completely separated state. This state is shown in FIG. 3 and FIG. 12, and this disengaged state is maintained even when the pressing state of the pressing cylinder 12 is released.

Next, when the pressing cylinder 12 is pressed from the detached state of the suction cup body 1 shown in FIG. 3 and FIG. 12, the step of the cutting edge-shaped engaging projection 17 of the rotor 16 on the guide cylinder 6 is formed. The engagement with the portion 8'is released, and the rotor 16 is simultaneously returned by the elastic force of the spring 21 and is rotated, so that the cutting edge-shaped engaging projection 17 is locked until now. It moves along the axial guide groove 11 next to ′, and along with this movement, the collar portion 19 of the shaft rod 18 and the inner cylinder
The central portion of the suction disc body 1 is pulled upward through the engagement with 20, and the suction state shown in FIGS. 1 and 10 is obtained. In this way, the suction disc body 1 is detached from the wall surface A or the like by a simple one-touch operation of just pressing (knocking) the pressing cylinder 12 once, and from this detached state, the pressing cylinder 12 is pressed once again (knocking). The suction disc body 1 can be sucked again by a one-touch operation.

Further, the operation of the second embodiment will be described. That is, the suction state shown in FIG. 13, that is, the upper cylinder body 36 of the pressing cylinder 35 is projected to the maximum above the opening of the outer cylinder 35, Child 50

(Corresponding to the rotor 16 of FIG. 12) has the same positional relationship as the positional relationship shown in FIG. 12, the upper cylinder body 36 of the pressing cylinder 35 is pressed from the suction state to the wall surface A of the suction plate body 30. Then, the pressing cylinder 35 is pushed down against the elastic force of the spring 45, and the rotor 50 is pressed down against the elastic force of the spring 55, so that the inner cylinder 46 is pressed accordingly. Suction cup body Te 30
The central portion of the suction plate body 30 is pressed and the suction plate body 30 becomes flat. This state is shown in FIG. 14, and the engagement positional relationship between the engagement portion 47 of the inner cylinder 46 and the cutting edge-shaped engagement projection portion 52 of the rotor 50 at this time is the same as that of the 11th embodiment. It is the same as the relationship shown in the figure.

As shown in FIG. 14, the pressing cylinder 35 is pressed to the maximum extent, the cutting edge-shaped engaging projections 52 of the rotor 50 come out of the axial guide groove 44 of the pressing cylinder 35, and a so-called rotary knock mechanism is provided. When the rotor 50 is rotated by the blade 50, the cutting edge-shaped engaging protrusion 52 of the rotor 50 is immediately adjacent to the step portion 41 ′ of the pressing cylinder 35 which has been previously locked by the elastic force of the spring 55. It is pushed down along the axial guide groove 44 until it is locked by the locking portion 40, the central portion of the suction cup body 30 is further pressed, and the outer peripheral edge portion 31
Is separated from the wall surface A or the like, and the suction cup body 30 is completely removed.

The positional relationship between the engagement protrusion 52 and the axial guide groove 44 in the pressing cylinder 35 is the same as the relationship shown in FIG. 10 in the first embodiment. It should be noted that this disengaged state is maintained even if the pressing state of the pressing cylinder 35 is released.

Next, from the detached state of the suction cup body 30 shown in FIG. 15, when the pressing cylinder 35 is pressed to the maximum against the elastic force of the spring 55, the pressing cylinder 35 compresses the spring 45. While being pushed down, the cutting edge-shaped engaging protrusions 52 of the rotor 50 engaged with the engaging portions 47 of the inner cylinder 46 are pushed out of the axial guide grooves 44 of the pressing cylinder 35, and the spring is instantly released. The rotor 50 is rotated by the action of 55 (see FIG. 14), and at the same time, the cutting edge-shaped engaging projections 52 of the rotor 50 are pushed up by the elastic force of the spring 45 into the two pressing cylinders 35. The central portion of the suction cup body 30 is moved upward by being locked to the step portion 41 ′ of the inclined surface portions 42 and 43, and by pulling up the inner cylinder 46 accompanying the pulling up of the rotor 50 by the elastic force of the springs 45 and 55. It is pulled into the adsorption state shown in FIG. In this way, the suction disc body 30 is detached from the wall surface A by a simple one-touch operation of pressing the push cylinder 35 once (knock), and the push cylinder 35 is pressed once (knock) from this detached state.
The suction disc body 30 can be sucked again by a one-touch operation.
