DETAILED DESCRIPTION

[0017] The technical solutions in the utility model are further described below with reference to the drawings and examples.

[0018] As shown in the drawings, Figures 1-3 The utility model discloses a galvanized part coating adhesion hammering test device, which comprises a base 1, a vertical plate 2, limiting tracks 8, a mounting rod 5 and a hammer head 7. The vertical plate 2 is fixed on the top of the base 1. The top of the base 1 is provided with a mounting seat 3. One end of the mounting rod 5 is rotatably connected to the mounting seat 3 through a rotating shaft 6. The hammer head 7 is fixed on the other end of the mounting rod 5. The limiting tracks 8 are two and both are arc-shaped. The two limiting tracks 8 are symmetrically arranged between the side wall of the vertical plate 2 and the top of the base 1. A channel for the sliding of the mounting rod 5 is formed between the two limiting tracks 8. The bottom of the base 1 is further provided with a plurality of support assemblies. The end of the base 1 is provided with a horizontal mounting groove 9. A positioning rod 10 is slidably arranged in the mounting groove 9. A spring 11 is further arranged in the mounting groove 9.
