[0024] In this embodiment, in addition to powering the insulation megohmmeter 1 by shaking the crank 3, the crank 3 can also be removed and the driving device can be used to drive the generator shaft of the insulation megohmmeter 1 to rotate, so as to improve the stability of the rotation of the generator shaft of the insulation megohmmeter 1. The driving device in this embodiment is used to modify the traditional hand-cranked insulation megohmmeter 1. Specifically, the user can clamp the mounting shell 14 on one side of the fixed shell 4 to one side of the insulation megohmmeter 1, and then the user can tighten the locking rod 16. The rotation of the locking rod 16 will cause one end of the locking rod 16 to pass through the threaded tube 15 and the mounting shell 14 in sequence and extend to the inner cavity of the mounting shell 14 to fit the surface of the insulation megohmmeter 1, thereby installing and fixing the driving device on the insulation megohmmeter 1.
