Nope, those things are glued together pretty well. I have no idea what module they used, how it is secured in there, length, etc......Most of these cheap lasers, especially the 532nm, are not meant to be repaired. They are modules and no two modules are the same (not true but you get the idea).
If it was a diode based laser then yes, it could be repaired (if it used a 12mm module to hold it). Even then it might not be possible, depends on the driver condition, space, etc....
Those lasers are basically disposable lasers. LaserBtb is far superior in quality and will last you many many years when handled properly but even those, when they die, they get tossed out.
I bought a cheap dead LaserBtb 405nm laser to see if I could open it and replace the diode, but I have YET to get it opened. I bought it over 3 months ago and its been a pain in the arse! The lasers finish is DESTROYED and it still wont open!
