[0040] According to the above-mentioned preferred technical solution, the workflow of the technical solution is described as follows:

[0041] According to the diagnosis needs, hammers of different weights are selected, and the cylinder 46 is placed between the teeth 36. After rotating the threaded convex strip 33, the teeth 36 are driven to gather together or move away from each other along the slide groove 35 by the coupling between the rotating ring 32 and the comb teeth 37, so as to clamp and fix the cylinder 46. When the plastic handle 11 is held to tap the patient's trunk with the tapping block 43, the pressure sensor 44 will first record the force of the tapping, and the tapping block 43 will shrink into the groove 42, compressing the arc-shaped plastic plate 47 and the airbag spring 48, and using the elastic potential energy of the arc-shaped plastic plate 47 and the airbag spring 48 for buffering. Before knocking, the length of the hammer rod 2 determines the force of the knocking. By pulling the sleeves 25 at the front and rear ends of the hollow tube 24, the hemispherical protrusions 23 are inserted into the slots 26 at different positions in the inner cavity of the sleeve 25, thereby realizing the change in the length between the hollow tube 24 and the sleeve 25. In addition, the C-shaped elastic support sheet 22 has greater elasticity and needs to be pulled by hand to move. The elasticity of the C-shaped elastic support sheet 22 can be used to make the hemispherical protrusions 23 more firmly stuck in the slots 26.
