Five, the specific embodiment:

Please see Figure 1, Fig. 2, Fig. 3, Fig. 4, the utility model mainly is made up of support 1, bench board 2, fork 4, swing arm 5, swing arm 6, guide groove 7, supporting base 8, bogie wheel 9, rest pin 10 and actuating device.Numbering 3 is the workpiece that are transferred among the figure.Wherein the central authorities at support 1 are fixed with bench board 2, structural feature of the present utility model is: bench board 2 both sides of A. on support 1 are provided with supporting base 8, bogie wheel 9 is installed on the supporting base 8, on bogie wheel 9, place fork 4, be provided with swing arm 5,6 in the inboard of fork 4, be fixed with guide frame 7 in the outside of supporting base 8, the top of guide frame 7 radially comprises the upper semi-circle of fork 4, and swing arm 5,6 is exposed; B. be provided with actuating device in the outer end of bench board 2, one of this actuating device top and fork 4 is connected.

By Fig. 1, Fig. 2, Fig. 4 as can be known: actuating device is made up of air cylinder driven slide unit 11, tooth bar 12, cylinder 13, gear 14, tooth bar 15, fork plate 16, quarter butt 17,18, vertical affixed fork plate 16 on the face of air cylinder driven slide unit 11 wherein, two fork pockets suit forks 4 of fork plate 16, gear 14 is installed by central authorities at air cylinder driven slide unit 11, the both sides of gear 14 and

tooth bar

12,15 engagements, one of them tooth bar 12 tail end links to each other with cylinder 13, the external end head of two

tooth bars

12,15 all has groove, has the quarter butt 17 and 18 that is fixed in fork 4 bottoms to insert in the groove.

Can further see from Fig. 1, Fig. 2, Fig. 3, Fig. 4: 2～4 bogie wheels 9 and guide frame 7 are respectively arranged on the fork 4 of bench board 2 both sides, the inboard of fork 4 is provided with swing arm 5,6 corresponding to four jiaos of each workpiece 3, the external end head of each swing arm has groove, and a jiao of workpiece 3 places in the groove of a cooresponding swing arm.
