[0026] The fixed elbow clamp 120 is arranged on the bottom surface of the mounting plate 100. At this time, the bottom surface of the mounting plate 100 forms a sample placement area 130. The sample is placed in the sample placement area 130 and is clamped and fixed by the fixed elbow clamp 120. At this time, the surface of the sample to be tested is exposed within the range of the ball drop hole 101.

[0027] The ball-dropping guide tube 140 is placed on the top surface of the mounting plate 100 and aligned with the ball-dropping hole 101 . The ball drops along the ball-dropping guide tube 140 and impacts the surface of the sample to be tested from the ball-dropping hole 101 .

[0028] During the actual test, the height of the support feet 110 is adjusted to ensure that the mounting plate 100 always remains level, eliminating the influencing factor of the uneven test surface when the exterior trim profile is placed on the ground. Combined with the accurate length of the ball drop guide 140, the accuracy of the ball drop height is guaranteed and the impact is at the exact position, thereby improving the accuracy of the test results.

[0029] Preferably, the support feet 110 are arranged at various corners of the mounting plate 100, and the support feet 110 are threadedly connected to the mounting plate 100 to adjust the height of the corresponding position of the mounting plate 100, thereby ensuring that the mounting plate 100 is always in a horizontal state by adjusting the height of each support foot 110.

[0030] Preferably, the end face of the ball dropping duct 140 is provided with a positioning plate 150, and the positioning plate 150 is horizontally placed on the top surface of the mounting plate 100, and the through hole of the ball dropping duct 140 and the ball dropping hole 101 are located on the same vertical line. Through the setting of the positioning plate 150, not only can the ball dropping duct 140 be firmly seated on the top surface of the mounting plate 100, but it can also be accurately aligned with the ball dropping hole 101, thereby ensuring the accuracy of the test results.

[0031] Preferably, a recessed groove is provided on the bottom surface of the mounting plate 100 to form a sample placement area 130 , and the fixed elbow clamp 120 is located in the sample placement area 130 , so as to facilitate fixing the installation position of the sample.

[0032] Preferably, at least one pair of fixed elbow clamps 120 are provided to clamp the two ends of the surface to be tested of the sample, thereby more securely clamping the sample to ensure that the sample remains stable and avoids displacement during the impact of the falling ball, and by applying balanced pressure to both ends of the sample, the force on the sample is evenly distributed in the entire test area to avoid local stress concentration, thereby obtaining more accurate and consistent test results.

[0033] Preferably, the fixed elbow clamp 120 includes a control handle 121, a rocker arm 122 and a chuck 123. The control handle 121 and the rocker arm 122 are connected by a connecting rod 124. The chuck 123 is arranged at the end of the rocker arm 122. The chuck 123 is lifted or pressed down by the control handle 121. The overall operation is simple, and it is convenient to clamp the sample.
