Since the process is carried out by first clamping the two sides of the workpiece and then gripping the periphery of the workpiece, the clamping member does not have the adjacent jaws pinched to the workpiece first, thereby avoiding damage to the workpiece. “When creating a grip to grasp the workpiece, please refer to the first to third figures and the first, the figure ' is to install the creation on the lathe, and place the workpiece (8) on the two - jaws (1 8) and two second central | (1 9) 戸 戸 bow ^ ), with the tie rod (B) screwed to the rod (3 3 2) rod (3 3 2), and the pull tube (cu Luo people g (c) screwed to the pull ring ( 23) Combination screw hole 9 M359385 (232). When the first-stage gripping action of this creation is carried out, please refer to the fifth figure, pull the pulling block (31) to the left with the tie rod (B), and pull the block (31). Pulling the second pull tabs (172) of the two second hook arms 07) to the left with the second pull tabs (311) on both sides, and rotating the two second hook arms (17) with the second drive bumps at the top (171) respectively = hooking the second slider (15)' so that the two brothers and one jaws (19) combined with the two second sliders are clamped inwardly to the left and right sides of the workpiece (Α). The gripping action of the second section, when the gripping action of the second section is carried out, as shown in the sixth and seventh figures, pull the pulling column with the pulling tube (c) to the left, and pull the column (21) to The first pull tab (211) on both sides faces the first pull rod (142) of the two hook arms (14) Rotating the two first-hook arms (14) and hooking the first sliders (the first jaws coupled to the two first sliders (12) with the first driving protrusions (14" at the top respectively (18) Tightly clamp the upper and lower sides of the workpiece (8) inwardly to match the positioning of the two second jaws (10).
