Further, the worker only needs to rotate the threaded rod, so that the limiting block is connected with the second limiting groove after penetrating through the fixing rod, thereby keeping the fixing rod stable. In this process, the rubber sheet and the sealing gasket cooperate to improve the connection tightness between the electrode plastic shell and the fixing ring, thereby improving the sealing effect of the electrode plastic shell, and further reducing the probability of liquid leakage of the electrode plastic shell.

[0020] 2. In the application, when the worker needs to install the electrode bulb, the worker needs to connect the fixing rod with the fixing groove, and rotate the threaded rod, so that the threaded rod moves towards the fixing rod, thereby connecting the limiting block with the second limiting groove after penetrating through the fixing rod, and further keeping the fixing rod stable under the action of the limiting block.
