when the motor 6 fails to cause the machine tool main body 2 to rapidly drop, the two first rods 403 drive the two third rods 407 to rapidly move, so as to drive the two sliding plates 406 to rapidly slide towards two sides on the inner wall of the anti-dropping box 405, and at the moment, the two sliding plates 406 can generate very large internal contact stress, so that the non-Newtonian fluid is rapidly changed into a solid, the sliding of the two sliding plates 406 is prevented, the two first rods 403 cannot rotate, the machine tool main body 2 is prevented from dropping, the machine tool main body 2 can be better protected, and the machine tool main body 2 is prevented from dropping due to the failure of the motor 6 in the height adjusting process of the machine tool main body 2, and the machine tool main body 2 is prevented from being damaged;

the motor 6 can drive the reciprocating screw 902 to rotate while rotating, so as to drive the second slide block 9 to slide on the inner wall of the cooling box 8, the second slide block 9 drives the sliding plug 801 to slide back and forth on the inner wall of the cooling box 8 through the two eighth rods 901, under the action of the sliding plug 801, cooling liquid in the cooling box 802 enters the cooling box 8 through the liquid inlet pipe 804, the cooling liquid in the cooling box 8 enters the spiral pipe 803 through the liquid supply pipe 805 to cool the motor 6, the phenomenon that the motor 6 is damaged due to overhigh internal temperature in the working process of the motor 6 is avoided, and the service life of the motor 6 is prolonged;

after the cooling liquid in the spiral pipe 803 cools down the motor 6, can flow back to the cooling box 802 again through drain pipe 806, the heat in the cooling liquid can be got rid of to the fin on the cooling box 802, cools down the cooling liquid for the cooling liquid can be by reuse, prevents the waste of resource.
