Further, described helmet is enclosed within shell, and lower contact two ends are overlapped in shell and connected with outer casing respectively, and plug is enclosed within connected with outer casing.
Further, described elasticity volume pin comprises the elasticity volume pin I be located on cage assembly and the elasticity volume pin II be located on frame assembly.
Further, elasticity volume pin I is located at described outer casing end and connects with helmet inner chamber and hold, and lower contact and connected with outer casing socket-connect and hold.
Further, elasticity volume pin II is located at skeleton upper end tube connector and the socket link of frame assembly.
Further, elasticity volume pin II is located at skeleton lower end and the plug link of described frame assembly.
Further, described skeleton lower end is connected with adopting screw between lower contact.
Further, the connection between shell and lower contact, the connection between lower contact and connected with outer casing all adopt positioning key to add threaded collar connection.
Compared with prior art, the beneficial effects of the utility model are:
The fixed connection structure of this logger skeleton and shell, this structure locates in the anti-rotation of socket and plug and cage assembly the anti-rotation form all adopting alignment pin fixing, the requirement that tool housing wall thickness is relatively thin can not only be realized, and can when the arbitrary connector in not dismounting skeleton two ends, realize frame assembly and cage assembly is completely independent, the uniformity that the phase place of tool housing assembly and frame assembly is transmitted can be ensured, simultaneously instrument assembling and keep in repair simple and easy to do.
