DETAILED DESCRIPTION

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Example 1, by Figure 1 The present invention relates to a protective screw with an anti-corrosion coating, comprising a head 1, a rod body 4 fixedly connected to the bottom of the head 1, a rotating groove 3 provided at the top of the head 1, and an auxiliary mechanism 2 provided at the top of the head 1, the number of auxiliary mechanisms 2 being two.

[0024] Specifically, by Figures 2-4 The auxiliary mechanism 2 includes a top frame 201 fixed to the top of the head 1. An inner shaft 209 is rotatably connected inside the top frame 201. An adjusting plate 203 is fixedly sleeved on the outer side of the inner shaft 209. The adjusting plate 203 is parallel to the top frame 201 and has a through hole 2010. A sleeve block 207 is fixedly connected inside the top frame 201, and the top of the adjusting plate 203 abuts against the top of the sleeve block 207. An abutment bracket 202 is fixedly connected to the top of the top frame 201. A guide post 208 is fixedly connected inside the top frame 201, located below the adjusting plate 203. The outer side of the guide post 208... A guide block 2012 is movably sleeved on the side. A plug rod 2011 is fixedly connected to the side of the guide block 2012 near the adjustment plate 203. The adjustment plate 203 is provided with a plug hole 2013 on the side near the guide block 2012. The plug rod 2011 is inserted into the plug hole 2013. A sleeve block 207 is fixedly sleeved on the outside of the guide post 208. A spring 206 is fixedly connected between the sleeve block 207 and the guide block 2012. The spring 206 is sleeved on the outside of the guide post 208. A lever 204 is fixedly connected to the outside of the guide block 2012. A side groove 205 is provided on the outside of the top frame 201. The lever 204 is slidably connected to the side groove 205.

[0025] In the initial state, the insertion rod 2011 is inserted into the insertion hole 2013, and the spring 206 is stretched. First, the lever 204 is moved to slide along the side groove 205, which drives the guide block 2012 to slide along the guide post 208. At this time, the spring 206 is stretched again, and the insertion rod 2011 is moved until it is removed from the insertion hole 2013, releasing the restriction effect on the adjusting plate 203. Then, the adjusting plate 203 is rotated around the inner shaft 209 until it abuts against the abutment bracket 202. At this time, the adjusting plate 203 is perpendicular to the top frame 201. Then, the lever 204 is released. At this time, the spring 206 returns to its original position, which drives the guide block 2012 to slide along the guide post 208 and approach the sleeve block 207. At the same time, the insertion rod 2011 moves horizontally until it abuts against the adjusting plate 203, thus limiting the adjustment plate 203. Finally, the outer rod body is passed through the two through holes 2010 and rotated to twist and disassemble the rod body 4.

[0026] Specifically, by Figure 1 As shown, the outer surface of shaft 4 is coated with an anti-rust coating, which is an epoxy zinc-rich primer;

[0027] In use, an epoxy zinc-rich primer is applied to the outer surface of the shaft 4, which can firmly adhere to the surface of the shaft 4 and remain stable in various complex chemical environments, thereby ensuring the anti-rust effect of the shaft 4.
