The utility model discloses a clamping mechanism and operation platform, clamping mechanism is used for setting on the lateral wall of operation platform to
resist pressure and place on the object of fixed object of operation platform, and clamping mechanism includes the arm of resistance pressure and support arm, wherein, one end of the arm of resistance pressure and the first end of support arm are rotatoryly connected in the first direction, and the other end of the arm of resistance pressure is used for resisting pressure and the object of fixed object in the Z axle direction, the second end of support arm is provided with rotating
assembly to drive support arm and rotate in the second direction through rotating
assembly, and the plane of first direction and the plane of second direction are perpendicular. Through setting clamping mechanism whole on the lateral wall of operation platform, do not occupy the table space of operation platform to increase the effective operation space of operation platform table face. And, through the rotatory connection in the first direction and the rotatory connection in the second direction, greatly expand the resistance
pressure range of the arm of resistance pressure, improve the resistance pressure coverage of the arm of resistance pressure, and then guarantee the resistance pressure effect.
