Clamping mechanism with detachable positioning member

A clamping mechanism, comprising:

• a positioning member;
• a support plate defining a through hole;
• a frame fixed to the support plate and defining a receiving groove, wherein the frame comprises a bottom plate and two side plates extending from an edge of the bottom plate in parallel, each side plate defining a pivot hole and an assembly hole;
• a fastening assembly rotatably received in the receiving groove of the frame, wherein the fastening assembly comprises a fastening member sleeved on the pivot shaft, a pivot shaft extending through the pivot holes of the side plates, and an elastic member compressed between the bottom plate and the fastening member, the positioning member extends through the through hole of the support plate, and is clamped between the fastening member and the frame under an elastic force of the elastic member;
• and
• an operating assembly resisting the fastening member and configured to push the fastening member, thereby driving the fastening member away from the positioning member, wherein the operating assembly comprises an operating pole extending through the assembly holes of the side plates, a resisting member sleeved on the operating pole, and a pin fixing the resisting member to the operating pole.
