Abstract:
1. A positioning device for a turnable table of a saw machine, the saw machine including a base defining a top and bottom surface, a turnable table rotatably located on the base, and a cutting unit arranged on the turnable table, said positioning device comprising: a pivot shaft mounted to the turnable table; a first pressing member coupled to the pivot shaft; a second clamping unit forming a second pivot portion for pivotally coupling on the pivot shaft, a second clench member corresponding to the bottom surface of the base, and a second pressing member corresponding to the first pressing member oppositely extending from the second pivot portion relative to the second clench member; a coupling unit interposed between the first and second pressing members, the coupling unit having a first coupling member pivotally connected to the first pressing member, a second coupling member for pivotally connecting the first coupling member and the second pressing member, and a trigger coupled to the second coupling member; and wherein manipulating the trigger drives the first and second coupling members such that the first and second pressing members are drawn toward or away from each other for pivotally driving the second clench member to unclamp or clamp the base.
