[0013] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the preferred embodiments of the present invention are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the patent claims of the present invention. Based on the examples in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figure 1 and Figure 2 As shown, the rust-proof screw involved in this embodiment includes a rotating part 1 and a stud part 2, the stud part 2 is provided with a spiral guide groove 3, the rotating part 1 is provided with an oil filling groove 4, and the oil filling groove 4 and the guide groove 3 are connected to an oil guide channel 5, part of which is provided on the rotating part and the other part is provided on the stud part.

[0017] Furthermore, the depth direction of the oil filling groove 4 is consistent with the axial direction of the stud portion 2.

[0018] Furthermore, the length extension direction of the oil guide channel 5 is consistent with the axial direction of the stud portion 2 .

[0019] In this embodiment, the screw is screwed into the threaded hole on the connecting component. When the two are rusted due to long-term exposure to the air, the screw is difficult to remove. At this time, an external filling tool can be taken out, lubricating oil or rust remover can be added, and lubricating oil or rust remover can be added to the oil filling groove 4. The agent is transported along the oil guide channel 5 and the guide groove 3, and penetrates the connection between the outer wall of the screw and the inner wall of the threaded hole for lubrication.

[0020] Example 2

[0021] See also Figure 1 and Figure 2 As shown, the rust-proof screw involved in this embodiment is further configured as follows on the basis of embodiment 1: a step 6 close to the bottom of the groove is provided in the oil filling groove 4, and a soft rubber plug 7 with one end against the step is embedded in the oil filling groove 4.

[0022] Furthermore, the soft rubber plug 7 is buried in the oil filling groove 4 .
