6th, the pressure detecting part being equipped with using the utility model can be applied to pressure inspection by the flat-top of flat-head type mine
The downward power on part top is surveyed, pressure detecting part is driven to move downward, when the graphite guide torch being equipped in pressure detecting part enters
During graphite guide electric circle, the entire warning circuit of unicom so that alarm starts to alarm；
7th, the wire guide being equipped with using the utility model pedestal facilitates the power Transmission of entire flat-head type mine laneway,
It avoids damaging conducting wire when staff is in construction operation, so as to avoid generating corresponding security incident；
8th, the graphite guide electric circle and graphite guide torch being equipped with using the utility model, it can be ensured that when warning circuit is closed
Due to using graphite as conductive material without generating spark, so as to reduce security risk；
9th, the utility model is easily installed, detachable and supporting effect is reliable and can send letter when top pressure overload occurs
Breath ensures the flat-head type tunnel mining bracket of work people's life security, has stronger practicability.
