The connection: ί;, the nozzle 4 in the figure is set on the rear shaft 30 and two; r' and the nozzle 4° can be connected to the external vacuum in the present embodiment. In the example, the rear axle is a screw 51, and the screw is two Through the through hole Μ channel 52', the inside is through the sturdy shell hole 3 2 and the nozzle 4 〇. Please refer to the figure to Fig. 3, the embodiment (4) is intended to be - In the drawings, the above-mentioned vacuum suction moving mechanism 91 is not shown, the t stomach imitation straight 1 series is set at 91], and the pivot arm 911 mountain includes a pivot arm on the arm 911, the body 90 The other-known group is provided with the above-mentioned pivoting arm 91 of the vacuum suctioning and moving mechanism 91], and as can be seen from FIG. 3, the moving vacuum suction device of the moving mode is moved downwards and turns. Lace [S] Set 匣70, at 6 201228893 The 匣70 content is provided with a plurality of objects 7 1 such as film or paper. At this time, the first telescopic suction cup set at the front end of the front shaft 10 1 2 will be adjacent to the adsorbed material 7 1. Please refer to FIG. 1 to FIG. 5, wherein FIG. 4 is a second schematic diagram of the operation of the preferred embodiment of the present invention, and FIG. 5 is a cross-sectional view of FIG. It can be seen from the figure that the first telescopic suction cup 12 assembled at the front end of the shaft 10 is adjacent to the suctioned object 7 1 , and the external vacuum connected by the suction nozzle 40 can be connected. (Unillustrated) vacuuming operation is performed. At this time, the second telescopic chuck 33 assembled at the front end of the rear axle 30 is retracted (as shown in FIG. 5) due to the vacuum relationship, and the front axle 10 is simultaneously The first telescopic chuck 12 assembled at the front end of the front axle 10 absorbs the sucked object 7 1 and will be The suction 7 1 is taken out of the magazine 70 by a distance. The aforementioned slip distance can be compared by the reference numerals Η and Η 1 of Figs. 3 and 4.
