a C transmission step (404) is arranged at one end of the sleeve I (4) provided with the E threaded hole (403); correspondingly, a D transmission step (502) which is used for being in transmission fit with the C transmission step (404) is arranged on the end, which is used for being butted with the No. i sleeve (4), of the No. ii sleeve (5); after the sleeve No. i (4) and the sleeve No. ii (5) are butted, a rotating gap exists between the C transmission step (404) and the D transmission step (502); the other end of the II sleeve (5) is provided with a B transmission ring (503) which has the same pattern as the head of the dismounting tightening bolt (6), and the size of the B transmission ring (503) is larger than that of the head of the dismounting tightening bolt (6);
the length of the screw rod for detaching the puller bolt (6) meets the requirement that the screw rod can enter a B groove body (401) inside the sleeve (4) No. i when the screw rod is sequentially screwed into an F threaded hole (501) and an E threaded hole (403) until the head of the puller bolt (6) is detached and abuts against the A transmission ring (203) under the condition that the sleeve (4) No. i is in butt joint with the sleeve (5) No. ii.
6. The full thread stud disassembly and assembly tool of claim 5, wherein: the C transmission step (404) and the D transmission step (502) are both of fan-shaped structures.
7. The full thread stud disassembly and assembly tool of claim 6, wherein: the radian of the C transmission step (404) and the D transmission step (502) is 100 DEG and 150 deg.
8. A method for disassembling a full-thread stud is characterized by comprising the following steps: the method removes the full threaded stud from the threaded hole using the full threaded stud removal tool of claim 5;
the disassembly steps are as follows:
A. screwing an i-shaped sleeve (4) of the assembled full-thread stud disassembling tool onto a disassembling object, so that the outer end of the disassembling object extends into the B groove body (401) to be abutted against a screw rod of a disassembling jacking bolt (6);
B. the sleeve of the automatic wrench is sleeved into a B transmission ring (503) on a No. ii sleeve (5), then the automatic wrench is started, the automatic wrench drives the No. ii sleeve (5) to rotate, after a D transmission step (502) on the No. ii sleeve (5) and a C transmission step (404) on the No. i sleeve (4) form transmission fit, the No. ii sleeve (5) drives the No. i sleeve (4) to rotate, as the lead of the E threaded hole (403) is larger than that of the D threaded hole (402), a disassembly jacking bolt (6) gradually compresses an object to be disassembled, the friction force between the disassembly object and the thread of the D threaded hole (402) gradually rises to meet the disassembly requirement, and then the No. i sleeve (4) drives the disassembly object to rotate through the friction force until the disassembly object is separated from the threaded hole.
