The invention discloses a hoisting and fixing device for an MJS drill rod. The hoisting and fixing device comprises a hoisting rope, a hoisting ring, a fixing screw, a sleeve, a circular pipe, a locking pin, a hoisting beam, the MJS drill rod, a horizontal hoisting pipe and a vertical hoisting hole site, a hoisting beam is arranged at the bottom end of the hoisting ring; the hoisting rings and the hoisting beam are fixed through fixing screws; a lifting rope is arranged at the upper end of the lifting ring; a sleeve is arranged at the bottom end of the hanging beam; the two sides of the middle upper end of the side face of the sleeve are each provided with a vertical hoisting hole site, and the positions of the two vertical hoisting hole sites are symmetrical. The lifting beam and the vertical lifting hole site are fixed through a lifting fixing rod; round pipes are arranged on the two sides of the middle of the side face of the sleeve correspondingly, and the positions of the two round pipes are symmetrical. A locking pin is arranged in the circular tube, and the circular tube and the locking pin are matched for use; a horizontal hoisting pipe is arranged on the sleeve on one side of the circular pipe; and the MJS drill rod is arranged in the casing pipe. The device is reasonable in design, convenient to operate and high in working efficiency, and the cavity shape has a large mode volume on the crystal, so that a large light beam filling factor is achieved, and high-efficiency fundamental frequency light output is ensured.
