Detailed Description

As shown in fig. 1, the detachable high-tension lead screw comprises a lead screw 1 and a plurality of nuts 2, wherein the plurality of nuts 2 are in threaded connection with two ends of the lead screw 1, and in this embodiment, the specific number of the nuts 2 is two.

As shown in the figures 2-3, the screw rod 1 comprises a first screw rod 1-1 and a second screw rod 1-2, and the first screw rod 1-1 and the second screw rod 1-2 form a complete screw rod. The lower end face of the screw rod I1-1 is cut with a lower section 1-1-1, the upper end face of the screw rod II 1-2 is cut with an upper section 1-2-1 matched with the lower section 1-1, and the upper section and the lower section are combined together to form a complete cylindrical structure. The lower section 1-1-1 and the upper section 1-2-1 are connected together through a countersunk head bolt 1-3, and the section angle of the lower section 1-1-1 and the upper section 1-2-1 is an obtuse angle, so that the connection stability of the upper section and the lower section is ensured, and the connection strength is improved.

As shown in fig. 4-5, the nut 2 includes a nut split 2-1 and a nut split 2-2, and the two nut splits form a complete nut. The outer wall of the nut split body II 2-1 or the outer wall of the nut split body I2-2 is welded with a rocker 2-3, and the rocker 2-3 is rotated to realize that the nut 2 moves on the screw rod 1.
