The plurality of limit blocking blocks 5 are respectively adapted to the plurality of through openings. The elastic column 51 passes through the fixed ring 4 and extends into the hollow insert 3. The elastic column 51 is adapted to the plurality of limit blocking blocks 5.

[0027] The fixing ring 4 is provided with a through slot 6 , and a through hole is provided on the outer wall of the fixing ring 4 away from the through slot 6 . The through hole is the same as the hollow insert 3 and the through slot 6 . The through hole and the hollow insert 3 are both adapted to the elastic column 51 .

[0028] The disassembly and assembly mechanism 2 also includes a limit plug plate 7, two limit blocks 8, two positioning blocks 9, two round rods 11 and two telescopic springs 12. Limit slide grooves are provided inside both sides of the through groove 6. The limit plug plate 7 is slidably installed on the through groove 6. The two limit blocks 8 are respectively fixedly installed on the outer walls of both sides of the limit plug plate 7. The two limit blocks 8 are respectively adapted to the two limit slide grooves.

[0029] The outer walls of the two limit blocks 8 on the side away from each other are both provided with concave grooves, and the two positioning blocks 9 are respectively installed in the two concave grooves.

[0030] The two round rods 11 are fixedly installed in the two limiting slide grooves, respectively, and the two limiting slide grooves are slidably connected to the two positioning blocks 9 respectively.

[0031] The limit plug plate 7 is provided with a pull opening, and a handle plate 13 is fixedly mounted on the pull opening.

[0032] Choose one of the following based on usage:

[0033] 1. The insertion hole 1 on the hollow insert 3 is a through hole, and one end of the hollow insert 3 with a through hole passes through the insertion hole 1 on the cathode plate body 1, so that the limit stopper 5 can contact the outer wall of the other side of the cathode plate body 1;

[0034] 2. The insertion hole 1 on the hollow insert 3 is not a through hole, and the inner wall of the insertion hole 1 needs to be provided with a limit slot that matches the limit blocking block 5, so that the limit blocking block 5 can enter the limit slot for limit fixing.

[0035] The working principle of the alkaline etching solution electrolysis cathode plate provided by the utility model is as follows:

[0036] The first step: the present application selects 2, pulls the limit plug plate 7 by the handle plate 13 to move, causing the limit plug plate 7 to move in the direction away from the fixing ring 4, so that the elastic column 51 on the fixing ring 4 leaks out (the length of the elastic column 51 is slightly larger than the length of the hollow insert 3 and the fixing ring 4, so when the limit plug plate 7 is inserted into the fixing ring 4, the elastic column 51 can be squeezed, and the multiple limit blocking blocks 5 can be squeezed by the elastic column 51, so that the limit blocking blocks 5 are exposed through the through opening, and at the same time, due to the elastic effect of the elastic column 51, the elastic column 51 can be used to squeeze and limit the limit plug plate 7), and then the elastic column 51 is pulled out, and the elastic column 51 is squeezed in the absence of the elastic column 51. Under the action of pressure, the limit blocking block 5 can enter the hollow plug tube 3 through the through opening, and then the hollow plug tube 3 is inserted into the second plug hole on the cathode plate body 1 through the socket one on the cathode plate electrode. Similarly, the elastic column 51 is inserted into the hollow plug tube 3 through the through hole on the fixing ring 4, and then the multiple limit blocking blocks 5 are squeezed by the elastic column 51, so that the limit blocking blocks 5 enter the limit slot through the through opening, and then the handle plate 13 is released. The limit plug plate 7 will be inserted into the limit plug plate 7 under the action of the telescopic spring 12, and then the limit plug plate 7 is pushed hard, so that the limit plug plate 7 squeezes the elastic column 51 to form a limit fixation.
