Adhesive force test fixture

The utility model discloses an adhesive force test fixture which comprises a U-shaped connector (1) and a T-shaped pin (2). Vertical arms on two sides of the U-shaped connector (1) are provided with two first round holes (3) which are coaxial and have the same diameter. A second round hole (4) is formed at the center of a cross arm of the U-shaped connector (1). A third round hole (5) is formed in the vertical end, close to the bottom, of the T-shaped pin (2). The T-shaped pin penetrates through the second round hole (4) in the U-shaped connector and is connected with the U-shaped connector in a non-fixed mode. Through adoption of the structure that the vertical arms of the U-shaped connector are connected with a part to be tested and the structure that the T-shaped pin and the cross arm of the U-shaped connector form the non-fixed structure, the adhesive force test fixture eliminates shear failure between coatings or between a coating and a base material due to existence of torsion in the testing process, th
