Similar word should be construed as the meaning for including rather than exclusive or exhaustive meaning；That is, being " including but not limited to "
Meaning.
Fig. 1 is the external structure schematic diagram of the downhole cable cutter of the utility model embodiment；Fig. 2 is the utility model
The assembling schematic diagram of the shearing mechanism of embodiment；As shown in connection with fig. 2 by Fig. 1: a kind of downhole cable cutter, including shearing mechanism
3；Shearing mechanism 3 includes ontology 31 and cutting assemblies；Cutting assemblies connection on the body 31；31 side of ontology has longitudinal lack
Mouthful；The longitudinal breach are for penetrating into downhole cable in ontology 31；Electricity is snapped down to along downhole cable according to gravity in ontology 31
When cable root, the top of fish connecting with cable root is inserted into 31 in ontology, and is started cutting assemblies and cut downhole cable.
Further, Fig. 3 is the structural schematic diagram of first scissors of the utility model embodiment；In figures 1 and 3, on
State cutting assemblies, including identical first scissors 32 of structure and the second scissors；The upper end of first scissors and the second scissors has respectively
There are blade part, lower end to be respectively provided with distending portion；First scissors and the second scissors are connected in a manner of mirror image each other by axis 33
The two sides of ontology 31；When downhole cable is inserted between the distending portion of the first scissors and the distending portion of the second scissors, the first scissors
And second scissors rotating around axis 33 rotate, the blade part pairing of the blade part of the first scissors and the second scissors；The pairing can be cut
Disconnected downhole cable.
Further, in Fig. 1, downhole cable cutter further includes two weighted levers 2；2 side of weighted lever setting is vertical
To slot；Longitudinal slot is for penetrating into downhole cable in weighted lever 2；Weighted lever 2 is connected to the top of shearing mechanism 3, for mentioning
