Tool for disassembling and assembling coal mining equipment

The tool comprises a main supporting seat, a horizontal sleeve hole is formed in the upper portion of the main supporting seat in a front-back penetrating mode, six sliding cavities are formed in the inner wall of the sleeve hole, the sliding cavities are arranged in a centripetal circumferential equal-angle mode relative to the sleeve hole, six main sliding grooves are formed in the rear portion of the main supporting seat, and the main sliding grooves are communicated with the sleeve hole. The main sliding grooves are arranged in a centripetal circumferential equal-angle mode relative to the sleeve hole, and the main sliding grooves are communicated with the sliding cavities in a front-back corresponding mode. A motor is controlled to rotate, a transmission ring can rotate forwards and backwards through a worm, a worm gear and a main supporting cylinder, and when the rotating direction of the transmission ring is opposite to the eccentric direction of a guide groove, through cooperation of a polished rod, a
