Generally speaking, the welding fixing method is simple, has high installation firmness and low contact resistance, while the bolt installation is easy to replace without damaging the surrounding coating and the coating on the back of the steel plate during replacement. Before installing the sacrificial anode, the surface of the protected metal needs to be prepared. First, the surface of the protected metal is cleaned to remove impurities such as grease and dust on the surface, and then sandpaper or a metal brush is used to remove surface oxides. Finally, it is cleaned with a solvent or an acid solution and rinsed with clean water to ensure close contact between the anode and the protected metal surface. In the prior art, when installing the sacrificial anode, the sacrificial anode is mostly installed on the protected metal surface through the mounting frames at the left and right ends of the sacrificial anode. During the installation process, the relative position between the sacrificial anode and the protected metal surface is fixed. Affected by the installation workers' skills and the size deviation of the installation components, the fit between the sacrificial anode and the protected metal surface is not tight enough, which affects the protection effect of the sacrificial anode.

A replacement hole 3 is provided on the front surface of the shell 1, which is convenient for replacing the sacrificial anode. Both upper and lower surfaces of the shell 1 are provided with clamping holes 4. A cover plate 5 is placed inside the replacement hole 3 to close the replacement hole 3. Both upper and lower ends of the cover plate 5 are provided with elastic clamping plates 6. The triangular plate at the rear end of the elastic clamping plate 6 is clamped with the clamping hole 4. The position of the cover plate 5 and the shell 1 is restricted by the clamping of the elastic clamping plate 6 with the clamping hole 4. The rear end of the shell 1 is an open structure. The rear end between the upper and lower inner walls of the shell 1 is respectively provided with limit plates 7 to restrict the position of the sacrificial anode in the shell 1. A rubber pad 9 is provided on the rear side of the shell 1 to reduce external dust from entering the shell 1. The arc surfaces on the left and right ends of the cover plate 5 are provided with anti-slip grooves 11, which are convenient for applying force to the cover plate 5 and removing the cover plate 5 from the replacement hole 3;

[0022] The pressing mechanism 8 is arranged on the rear side of the cover plate 5. The pressing mechanism 8 includes a guide column 81, a spring 83 and a pressure plate 84. The guide columns 81 are respectively arranged on the rear side of the cover plate 5. The pressure plate 84 is longitudinally slidably connected between the outer arc surfaces of the guide columns 81. The outer arc surfaces of the guide columns 81 are movably sleeved with springs 83. The rear ends of the springs 83 are fixedly connected to the pressure plates 84. The pressing mechanism 8 also includes an internal threaded ring 82. The internal threaded ring 82 is respectively threadedly connected to the screw grooves of the outer arc surfaces of the guide columns 81. The internal threaded ring 82 is respectively fitted with the front ends of the springs 83. The internal threaded ring 82 is rotated, and the internal threaded ring 82 is threadedly connected to the guide columns 81, so that the internal threaded ring 82 moves up and down to adjust the extension and contraction amplitude of the spring 83.

The tension spring 85 is movably sleeved on the outer arc surface of the guide column 81.

Under the elastic force of the spring 83, a backward force is applied to the front surface of the pressure plate 84.
