The utility model discloses a pressing mechanism, including an eccentric wheel with a supporting seat, an eccentric wheel connected with the support seat, and a reference table for locating the L type border under the eccentric wheel. The rotating shaft of the eccentric wheel is fixed to the support seat, and the support seat drives the eccentric wheel to move towards the L border frame when it is under pressure; and the center of rotation of the eccentric wheel is made. The angle between the end of the eccentric wheel and the horizontal plane is A, 0 degrees < A < 90 degrees. By setting the eccentric wheel which is connected with the support seat, the utility model enables the support seat to drive the eccentric wheel to move, and at the same time is used to locate the L type frame by setting the datum table so that the supporting seat drives the eccentric wheel to press the vertical face or the horizontal plane of the L frame when it is under pressure, and the eccentric wheel is acting on the eccentric moment. The downward rotation is pressed on the horizontal or vertical face of the L frame, thus realizing the power only in one direction, and the surface of the two direction of the L frame is clamped simultaneously.
