Reference numeral (12) is an inverted dish-shaped metal fitting, in which a ring-shaped magnet (7) is mounted inside, fixed by the magnetic force of the magnet, and a mounting hole (13) is formed in the center of the upper surface. (14) is a connector made of synthetic resin, and has a head (14A) having a diameter larger than the mounting hole (15) formed at the tip of the arm (9) at the upper end and a split groove (16) at the lower end. Glans (14
B) is formed between both parts (14A) and (14B) with a body part (14C) having a smaller diameter than the mounting hole (15). With this structure, first, the glans (14B) is first inserted into the mounting hole (15) of the arm from the upper surface, and then the glans is reduced in diameter into the mounting hole (13) of the mounting tool (12). When plugged in,
After insertion, the glans (14B) expands its diameter by its own elastic force as shown in Fig. 7 to prevent it from coming off. Thus, the magnet (7) is attached to the arm (9).

As shown in the figure, the protrusion (10) is inserted into the long width portion (L) of the deep groove (11A). Next, the arm (9) is rotated as shown by the broken line in FIG. 1 to rotate to the canister suction position (Z). In this state (see FIG. 4), even if the arm (9) is pulled forward, the protrusion (10) and the deep groove (11A) are engaged with each other to prevent the arm from coming out forward, so the can is removed. The arm does not come off when it is used.
