Furthermore, the compressed air from the front ends of the inner passages 141 can be further distributed to the jaw driving devices 16, 17, 18, 19 through a plurality of gas pipes (not shown but including the pipe joints 137). The pneumatic cylinders 162, 172, 182, and 192 provide propulsive power of the pneumatic cylinders 162, 172, 182, and 192.

Thereby, the compressed air can send the gas of the inner passages 141 of the rotating main shaft 14 to the inlet/outlet ports of the pneumatic cylinders 162, 172, 182, and 192 through the gas pipes, thereby making the air pressures The cylinders 162, 172, 182, 192 drive the jaws 121, 122, 123, 124 to perform a pinch action.
值得注意的是，在送氣的過程中，由於該些氣體管件主要係設置在該夾爪機構12內，(只有少部分，例如管接頭137，係位在該轉盤11內)，因此當該轉盤11、該夾爪機構12及該旋轉主軸14三者受該驅轉裝置15(第二圖)帶動而相對該支撐套筒14旋轉時，該些氣體管件之複雜管線不會發生纏繞糾結的問題。再者，該些夾爪驅動裝置16、17、18、19之氣壓缸161、171、181、191可驅動該些夾爪121、122、123、124同步地接近或遠離該轉盤11的軸心線X1，藉以夾住圓形或正方形的管件。不僅如此，由於該夾爪機構12具有兩個獨立的第一從動輪126以及該第二從動輪128，因此其中一對的夾爪驅動裝置16、17之氣壓缸161、171與另一對的夾爪驅動裝置18、19之氣壓缸181、191可分別驅動該第一對夾爪121、122與該第二對夾爪123、124，使其位移量不同，藉以夾住橢圓形或長方形的管件。 It is worth noting that during the air supply, since the gas pipe members are mainly disposed in the jaw mechanism 12 (only a small portion, such as the pipe joint 137, is located in the turntable 11), therefore, the turntable 11. When the jaw mechanism 12 and the rotating spindle 14 are driven by the driving device 15 (second drawing) to rotate relative to the supporting sleeve 14, the complicated pipelines of the gas pipes do not have the problem of winding entanglement. . Furthermore, the pneumatic cylinders 161, 171, 181, 191 of the jaw driving devices 16, 17, 18, 19 can drive the jaws 121, 122, 123, 124 to synchronously approach or away from the axis of the turntable 11. Line X1, by which a circular or square tube is clamped. Moreover, since the jaw mechanism 12 has two independent first driven wheels 126 and the second driven wheel 128, the pneumatic cylinders 161, 171 of the pair of jaw driving devices 16, 17 and the other pair The pneumatic cylinders 181, 191 of the jaw driving devices 18, 19 respectively drive the first pair of jaws 121, 122 and the second pair of jaws 123, 124 to have different displacement amounts, thereby sandwiching an elliptical or rectangular shape.
