Preferably, described tripping gear also comprises a unhook pin, and unhook bonding pad soldered is between the pin and unhook pin of piezo-resistance, and the unhook pin connects with the conductive strips that are connected terminals.
Preferably, described flexible member below is provided with sensitive switch, in case when flexible member flicked the unhook bonding pad, sensitive switch just moved, the signal of action is passed to signal receiving end.
Preferably, described flexible member is a compression spring, is looped around on the mobile jib that is packaged in the tripping gear, can move up and down on mobile jib.
Preferably, described unhook pin is one-body molded, comprise one with the welded plate of unhook bonding pad soldered, and the pin bayonet socket that the insertion conductive strips draw-in groove of end is set.
Preferably, described pin bayonet socket is " V " type, tightly buckle conductive strips draw-in groove.
Preferably, described pin bayonet socket comprises the first straight plate and the second straight plate, and the described first straight plate and the second straight plate are connected smoothly, and connects the 3rd straight plate that the one and second straight plate is 100-120 angle angle above the described second straight plate.
Preferably, described piezo-resistance also is provided with a distant news device, and by the signal brace temperature or the current status of piezo-resistance is passed to signal receiving end.
By technique scheme, the beneficial effects of the utility model are:
When piezo-resistance is subjected to extraneous very large disturbance, the temperature of piezo-resistance raises, because the unhook bonding pad is a soldered, then pad melts, the compression spring flicks the unhook bonding pad in installing fully, thereby makes equipment and electric power system out of touch, the security performance height, simple in structure, easy to use.
