The operating personnel can flexibly adjust the rotating speed of the rotating shaft structure 1 and the release frequency of the ink by pressing the three independent buttons arranged on the speed controller 6 according to specific experimental conditions.

[0029] In the structure, an electric motor 7 is further included, which is arranged on the end of the rotating shaft structure 1 and is electrically connected with the speed controller 6. The electric motor 7 rotates the rotating shaft structure 1, and the speed controller 6 controls the speed of the electric motor 7.

[0030] To make the specific structure of the handheld protection structure 2 clear, the handheld protection structure 2 includes a baffle 21, which is arc-shaped in cross section, is arranged on the rotating shaft structure 1, and is in clearance fit with the rotating shaft structure 1. The baffle 21 can effectively block the ink splashing generated in the marking process, avoiding the pollution of the ink to the operator or the surrounding environment.
