The detection component 3 is used to detect the center line of the ear 11 of the leaf spring 1 and the longitudinal center line of the leaf spring 1 (refer to Figure 2) verticality is measured. Specifically, the detection component 3 includes: a support column 31, a swinging member 32, a sleeve column 33 and a measuring member 34. The sleeve column 33 is cylindrical, and the sleeve column 33 is sleeved in the ear 11 of the leaf spring 1. The sleeve column 33 is adapted to the inner hole of the ear 11 of the leaf spring 1, so as to realize the use of the sleeve column 33 to replace the setting state of the inner hole of the ear 11 of the leaf spring 1 as a whole, so as to facilitate the detection of the setting state of the inner hole of the ear 11 of the leaf spring 1 and the verticality of the leaf spring 1. A U-shaped groove 311 is provided on one side of the support column 31, and the opening direction of the U-shaped groove 311 of the support column 31 is parallel to the longitudinal center line of the leaf spring 1. The support column 31 is provided with a connecting hole (not shown in the figure) in the U-shaped groove 311, so as to facilitate the subsequent connection of the swinging member 32 in the U-shaped groove 311 of the support column 31. The swing member 32 is V-shaped, and the V-shaped opening of the swing member 32 is arranged in a direction parallel to the longitudinal center line of the leaf spring 1, and measuring ends 321 are respectively arranged at both ends of the V-shaped opening of the swing member 32. The swing member 32 is respectively abutted against the upper and lower parts of the sleeve column 33 through the two measuring ends 321. The swing member 32 is provided with a first connecting shaft 322 away from the V-shaped opening, and the swing member 32 is rotatably connected to the U-shaped groove 311 of the support column 31 through the first connecting shaft 322.
