Further, the upper surface of the mechanism cover in the application is provided with chain guiding 1, wherein chain guiding 1 is used for
When mechanism cover is connected with five anti-interlockings, the chain installation for being oriented to 1 pair of five anti-interlocking can be passed through.
In addition, the upper surface of the mechanism cover in the application, which is additionally provided with, draws axis hole 2 and air plug hole 3, microswitch support
Position 7 and observation window mounting hole 4 are used to place the ground connection operating shaft in five anti-interlockings and behaviour are isolated specifically, drawing axis hole 2
Make the devices such as axis.Air plug hole 3 is for the installation or replacement to aviation plug.Wherein, for will be hindered in circuit when aviation plug
It is connected between disconnected place or isolated obstructed circuit, to make current flowing to realize scheduled function.Since mechanism cover is sealing
State, therefore air plug hole 3 can needed when aviation plug first just can be by mechanism cover deblocking to avoid installing or replacing by being arranged
The step of row is replaced.In addition, the application is also provided with microswitch support level 7 at the top of mechanism cover, wherein microswitch supports
