[0032] In the embodiment, the pulling assembly moves in the sleeve 21, the steel ball 26 hits the composite material, and the scale marks 29 on the scale block 22 cooperate with the indication assembly to scale and indicate the hardness test results.
[0033] It should be noted that the clamping block 31 can be made of wear-resistant material to increase the friction between the clamping block 31 and the carbon fiber reinforced composite material sample, so as to ensure that the sample does not slide or displace during clamping.
[0034] Specifically, the pulling assembly includes: an operating rod 23 slidingly arranged inside the sleeve 21, and a limiting block 25 fixedly arranged on the periphery of the operating rod 23; a spring 24 connected at one end to the top end inside the sleeve 21 and connected at the other end to the limiting block 25, for resetting the operating rod 23; a steel ball 26 fixedly arranged at the bottom of the operating rod 23, for hitting the composite material; and an indication assembly arranged on one side of the limiting block 25.
[0035] In the embodiment, the spring 24 is connected at one end to the top end inside the sleeve 21 and connected at the other end to the limiting block 25.
