Product Description
When A pushes down, B and C simultaneously move outward and parallel to the ground, achieving the goal of clamping the workpiece.
2. When A is loosened upward, B and C simultaneously move inward and parallel downward, achieving the purpose of loosening the workpiece.
Note: When A is loosened upward, because there is a stainless steel spring inside, B and C will not move upward together with A. Instead, they will simultaneously move inward and parallel downward.
