[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Referring to the drawings Figures 1-3 A vacuum gauge tube, comprising a vacuum gauge tube body 1, the vacuum gauge tube body 1 is placed in a protective shell, the protective shell comprises a box cover 2, a shell body 3 and a base 4, the box cover 2 is installed at the top of the shell body 3, and the base 4 is installed at the bottom end of the shell body 3;

[0028] At least one through groove is formed in the surface of the shell body 3, and a moving plate 3.1 is slidably connected in the through groove along the extension direction of the shell body 3, a limiting protrusion 3.2 is arranged at one end of the moving plate 3.1 close to the vacuum gauge tube body 1, the limiting protrusion 3.2 is in contact with the vacuum gauge tube body 1, and a buffer pad is attached to the end of the limiting protrusion 3.2, so as to buffer the impact force between the vacuum gauge tube body 1 and the limiting protrusion 3.2 during movement, and increase the friction between the limiting protrusion 3.2 and the vacuum gauge tube body 1 in the contact state; the limiting protrusion 3.2 is moved and the vacuum gauge tube body 1 is moved in the shell body 3 by sliding the moving plate 3.1 in the through groove of the shell body 3.

[0029] It can be understood that the outer surface of some vacuum gauge bodies has a stepped layer, and the limiting protrusion 3.2 can be arranged at the stepped layer, so that the limiting protrusion 3.2 is in contact with the stepped layer, and the vacuum gauge tube body 1 is more conveniently pushed.
