Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a split type pull rod comprises a threaded pipe 1, wherein two ends of the threaded pipe 1 are respectively in threaded connection with a first screw rod 2 and a second screw rod 3, threads on the first screw rod 2 and the second screw rod 3 are reverse threads, through holes 5 are formed in the end portions of the first screw rod 2 and the second screw rod 3, pin shafts 6 are inserted into the through holes 5, U-shaped forks 7 are sleeved outside the pin shafts 6, connecting plates 8 are welded at the end portions of the U-shaped forks 7, protruding blocks 9 are welded outside the threaded pipe 1, two groups of protruding blocks 9 are arranged on the protruding blocks 9, the two groups of protruding blocks 9 are symmetrically welded outside the threaded pipe 1, the threaded pipe 1 is convenient to rotate, a perforation 10 is formed in one side of each group of the protruding blocks 9, the perforation 10 is convenient for rotating the protruding blocks 9 by using a force applying rod, nuts 4 are in threaded connection with the outer portions of the first screw rod 2 and the second screw rod 3, after the lengths of the first screw rod 2 and the second screw rod 3 are adjusted, tightening the nut 4 locks the threaded pipe 1 against rotation of the threaded pipe 1.
