As shown in fig. 1, the utility model provides a post protecting cover of a diffusion pump of a cyclotron, which comprises a cover body 1 and a connecting piece 2, wherein the cover body 1 comprises a separation part 11, one end of the separation part 11 is connected with a containing part 12, the other end of the containing part 12 is connected with a fixing part 13, a positioning structure 131 is arranged on the fixing part 13, the positioning structure 131 is matched with the connecting piece 2, and the containing part 12 is matched with the post 3 of the diffusion pump of the cyclotron. When in use, after the accommodating part 12 is matched with the diffusion pump binding post 3 of the cyclotron, the connecting piece 2 is matched with the positioning structure 131, and the fixing part 13 is fixed on the heating rod protecting shell 4. In addition, an insulator 5 is further arranged between the heating rod protecting shell 4 and the cyclotron diffusion pump binding post 3, so that the heating rod protecting shell 4 and the cyclotron diffusion pump binding post 3 are mutually insulated, and a user is protected from electric shock hazard.

The isolation part 11 is used for shielding one end of the cover body 1 far away from the heating rod protection shell 4 to prevent a user from electric shock. The shape of the material can be changed according to the need, and the material can be square, cylindrical, diamond and other applicable shapes.

The accommodating portion 12 may be cylindrical, or may have other suitable shapes, such as a hollow prism. The end of the accommodating portion 12, which is engaged with the partition portion 11, is closed, and the end of the accommodating portion, which is engaged with the fixing portion 13, is provided with an opening 132, thereby accommodating the cyclotron diffusion pump binding post 3 and protecting the cyclotron diffusion pump binding post 3.
