the purpose of indicating mechanism work is achieved through the connection of the pins 32 and the circuit on the outer side, the indicating mechanism works simultaneously with the first electrode assembly 40, the second electrode assembly 50 and the power generation tube in the working process, at this time, the safety sheet 34 is hung on the top of the assembling block 62 in an inverted U-shaped mode, the pressure spring 64 jacks up the assembling block 62 due to the elasticity of the pressure spring, and the safety sheet 34 exerts downward acting force on the assembling block 62 due to the pulling force of the wiring terminal 33, so that the assembling block 62 is stabilized inside the module frame 30.
However, when the voltage-unstable fuse 34 or the terminal 33 in the indicating mechanism is broken, so that the downward acting force of the fuse 34 on the assembling block 62 disappears, the pressure spring 64 drives the assembling block 62 and the mounting block 63 to move upwards due to the elastic force of the pressure spring, the indicating sheet 70 is turned over by 90 degrees, the line fault of a worker is indicated, and the line fault is observed through an indicating window at the top of the module shell 10.
Example 2
In example 1, the above-mentioned indicator sheet 70 has certain defects in use, such as the problem that the indicator sheet 70 is easy to loosen and fall off, and the main reasons for the problem of loosening and falling off are as follows:
firstly, the state of the indicating piece 70 depends on the acting force of the safety piece 34 on the assembling block 62, but when the safety piece 34 is damaged, the acting force disappears, and the indicating function cannot be achieved; secondly, the state of the indicating sheet 70 depends on the position of the push rod 61, and in the present invention, the change of the position of the push rod 61 will cause the change of the state of the indicating sheet 70.
Therefore, in order to solve the above technical problem, the present invention further adopts another preferable technical solution:

When the ejector rod 61 needs to be locked, the buckling piece 22 is assembled on the locking piece 21 to lock the ejector rod, and the specific operation principle is as follows:
when the ejector rod 61 passes through the locking open pipe 212, at the moment, the opening on the locking open pipe 212 is large, after the buckling piece 22 is assembled on the threaded connector 211, the locking pipe 222 enables the opening to gradually shrink by extruding the locking open pipe 212, so that the inner diameter of the locking open pipe 212 is reduced to lock the ejector rod 61, the problem that the ejector rod 61 is loose or slides is avoided, the positioning pin 71 on the lower surface of the indicating piece 70 rotates to enter the positioning groove 631 in the working process, the positioning groove 631 is matched to hook the positioning pin 71, the stability of the ejector rod 61 and the mounting block 63 is greatly improved, and the problem that the indicating piece 70 is loose and falls off due to the sliding of the ejector rod 61 is avoided.
