When the user needs to replace the movable collet 11 and the fixed collet 30 to hold the object due to the demand of the operation (as shown in the eighth figure), It is only necessary to press the pressing portion 51 of the quick release member 50. As shown in the fourth and sixth figures, when the fixing rod 40 is in the state in which the fixing chuck 30 is fixed, the elastic member 55 is forced to be pressed as the quick-release member 50 is pressed by the pressing portion 51. The disassembling member 50 is pivoted with the positioning shaft portion 53 as an axis, and the fixing rod Because the two pivot portions 41 are pivotally slid in the pivot hole 52, they can be horizontally displaced from the fixing holes 21 of the cross bar 20, so that the fixing chuck can be detached.
反之當該固定夾頭30要固定時，則放開該按壓部51，令施力於該彈性件55之外力消失，使其快拆件50自動回位，同時帶動該固定桿40向內水平位移而穿套該橫桿20之固定孔21，令該固定夾頭30固定於橫桿20上(如第四、六圖所示)。On the contrary, when the fixing chuck 30 is to be fixed, the pressing portion 51 is released, so that the force applied to the elastic member 55 disappears, and the quick-release member 50 is automatically returned, and the fixing rod 40 is driven to the horizontal level. The fixing hole 21 of the cross bar 20 is inserted through the fixing rod 30 so that the fixing chuck 30 is fixed to the cross bar 20 (as shown in Figs. 4 and 6).
綜上所述，本創作在同類產品中實有其極佳之進步實用性，同時遍查國內外關於此類結構之技術資料、文獻中亦未發現有相同的構造存在在先，是以，本創作實已具備新型專利要件，爰依法提出申請。In summary, this creation has its excellent progress and practicality in the same kind of products.
