Position of the latch member) is provided to be movable.

To this end, a guide pin 42 is provided on the main body 10, and the latch member 41 has a guide hole 41a coupled to the guide pin 42. Therefore, the latch member 41 is moved in the direction of arrow A while the direction of movement is guided by the guide pin 42 during the reciprocating movement. Here, the formation position of the guide pin and the guide hole can be modified in addition to the above configuration. For example, it is also possible to form guide pins in the latch member and guide holes in the main body.

In addition, in consideration of the design of the vacuum suction port, the latch member 41 may be provided so as not to be exposed to the outside as shown in FIG. 4. In this case, as a means for the user to move the latch member 41 in the direction of an arrow A, an actuating portion 41b is provided on the latch member 41, and the position of the position corresponding to the actuating portion 41b is provided.

In this case, the operation part 41b may be formed in the shape of a working hole into which a sharp tool such as a clip is inserted through the opening 35a, or a working projection shape directly operated by a user's hand. In addition, the present invention may further include at least one separate operating unit installed at a different position from the operating unit 41b as indicated by reference numeral 41c to allow the user to easily operate the operating unit.

In addition, in forming the opening 35a, the opening 35a is operated at the position where the suction force is maximized when the vacuum suction port is attracted to the plate surface S by the rotation of the rotating member 35. The opening 35a is formed so as to be positioned on the? Therefore, when the user vacuums through the vacuum suction port, the opening 35a may guide the tightening degree of the rotating member 35.

In addition, the latch member 41 is rotatably installed in the direction of the arrow B on the main body 10 in the unlocking position. That is, the latch member 41 is installed to reciprocally rotate the guide pin 42 around the rotation center at the release preventing position, and is elastically biased toward the release preventing member 45 by the elastic member 47. . At this time, in order to restrict the rotation angle of the latch member toward the release preventing member at the release preventing position, the release preventing portion 40 further includes a stopper 43 protruding at a predetermined position of the main body 10. It may include.

The anti-loosening member 45 restricts the rotation direction so that the rotatable member 35 can be rotated in only one direction at the anti-loosening position. The plurality of locking jaws 45a and the latch member 41 are restricted. Rotating guide surface 45b). Therefore, a case in which the plurality of locking jaws 45a and the rotation guide surface 45b are formed as shown in FIGS. 2 and 4 will be described as an example.

When the rotating member 35 is rotated in the clockwise direction CW, the latch member 41 is in contact with the rotation guide surface 45b so as not to interfere with the locking step 45a. Therefore, the rotating member 35 is free to rotate in the clockwise direction without interference of the latch member 41.

When the rotation member 35 is to be rotated in the counterclockwise direction CCW, the latch member 41 is caught by the locking jaw 45a and is not rotated. Therefore, the rotation member 35 can be prevented from rotating in the counterclockwise direction at the release preventing position.

On the other hand, as shown in Figure 5, in the unlocking release position, since the latch member 41 does not interfere with the latching jaw (45a), the rotating member 35 is free in the clockwise or counterclockwise direction Rotation is possible.

As described above, the vacuum suction port according to the embodiment of the present invention includes an anti-loosening portion, so that when the latch member is positioned at the anti-loosening position in the vacuum suction state, even if there are external factors such as fine vibration, the screw tightening of the rotating member is released. Can be prevented. Therefore, it is possible to fundamentally solve the problem that the suction force of the vacuum adsorption portion on the plate surface is weakened by loosening the screw so that the vacuum suction port may fall off the plate surface.
