Fig. 6 A~Fig. 6 D offset (A) location A during triangle 2 is oriented to for swing piece 6 by Fig. 4 swing piece
Sectional view, the sectional view of (B) B location, the sectional view of (C) location of C, the sectional view of (D) D positions.Piece 6 is swung as Fig. 6 A to incline
Oblique occasion, as Fig. 6 B in B location, the gradient for swinging piece 6 is big, corresponding to the occasion, swings piece offsets triangle 2 the
The angle of inclination of inclined plane 51a, 51b of 1 acting surface 51 is big, therefore the face by suction portion 6a, 6b for swinging piece 6 is offset with swinging piece
The inclined plane 51b of triangle 2 is contacted (face contact) along face.If as Fig. 6 C, in location of C, swinging the gradient of piece 6 gradually
Ground diminishes, and the angle of inclination of inclined plane 51a, 51b of the 1st acting surface 51 due to swinging piece counteracting triangle 2 also little by little diminishes,
Therefore similarly, swing piece 6 and swing piece and offset the progress face contact of triangle 2.Then, contact when, contacted be not a little, but
Side.Afterwards, as Fig. 6 D, piece is swung in D positions and offsets triangle 2 in suction portion 4 just above in plane, piece 6 will be swung and led
To not inclined posture.In addition, in Fig. 6 A~Fig. 6 D, the 2nd occasion contacted by suction portion 6b is provided, still, even if

Fig. 7 side view is watched from white arrow direction.It is kept due to swinging piece 6 in the way of pivot joint, therefore as shown in figure 9, because swinging
The inclination of piece 6, it is different with the contact position for swinging piece counteracting triangle 2 to swing piece 6, when being contacted in I positions, swings the inclination of piece 6
Degree is maximum, with diminishing for the gradient for swinging piece 6, and contact position is in II positions, III positions, IV positions, and they are close
The position of suction portion 4.Like this, if the gradient for swinging piece 6 is different, swing piece 6 and swing the contact position of piece counteracting triangle 2
Put also different.In addition, the swing piece of acting surface 3 offsets triangle 2 in each contact position, the inclination with swinging the face that piece 6 is contacted
Degree correspondence, is not limited to above-mentioned 4 positions, no matter in which position, be basically identical shape.
Like this, if the inclination for swinging piece is different, because the contact position for swinging piece with swinging piece counteracting triangle is different,
In addition, in the different position, the gradient tilted respectively with swing piece for swinging piece counteracting triangle is basically identical, therefore no matter puts
Moving plate why the gradient of sample, with swing piece offset triangle contact when, contacted along face.
In addition, no matter because present embodiment swing piece offset triangle curved surface swing piece is inclined with what kind of degree
Tiltedly, swing piece and offset triangle not as before by 1 point, but contacted by face, contact the impact occurred, rub
Wipe not at 1 point, and disperse on the contact surface, can mitigate and swing piece, swing the abrasion that piece offsets triangle.In addition, by because swinging
The inclination of piece, swings the contact position difference that piece offsets triangle, thus dispersible contact position, and abrasion more mitigates.
In addition, in the present invention, because the contact that can not disperse to swing piece with swing piece counteracting triangle by 1 point is caused
Impact, friction, therefore strictly require to contact surface it is identical, in the longitudinal direction of above-mentioned acting surface, closer to suction region,
It is higher in upward direction, reduced with the movement in the direction at the end of acting surface, and it is minimum in the transverse ends of acting surface,
Uprised with being moved to middle, now, non-1 point of the identical such contact surface of the length of multiple points or certain degree can be formed,
Or the time contacted by guiding, by face, distance are touched by point with swinging piece counteracting triangle from by suction portion
Shorten, thus, contacting the impact caused, friction can be disperseed, and so, mitigates abrasion, the purpose of the present invention can be achieved.
