[0015] The technical solution of the utility model is described below in conjunction with the accompanying drawings and implementation methods.

[0016] like Figure 1 As shown, a threaded sleeve removal tool includes a threaded push rod 2, a rod sleeve 2a is provided on the top of the threaded push rod 2, and a cone 2b is provided on the bottom. The cone 2b is convenient for quick positioning during use; the threaded push rod 2 and the rod sleeve 2a are both provided with sockets, and the horizontal positions of the sockets of the two correspond.

[0017] A horizontal force rod 1 is inserted into the socket of the rod sleeve 2a, and the horizontal angle between the threaded top rod 2 and the horizontal force rod 1 is 90°. Limiting iron balls 1a are respectively provided at both ends of the horizontal force rod 1, and the diameter of the limiting iron balls 1a is larger than the diameter of the socket of the rod sleeve 2a.

[0018] The threaded top rod 2 comprises an upper rod body and a lower rod body, wherein the upper rod body is smooth, the lower rod body is provided with a plurality of threads, and a three-claw adjustment sleeve 3 is provided on the outside of the lower rod body.

[0019] The three-jaw adjustment sleeve 3 includes a first connecting nut 3a, which can reciprocate up and down along the threaded push rod 2. The outer wall of the first connecting nut 3a is symmetrically provided with three horizontally arranged screws 3b. The horizontal angle between the three screws 3b on the outer wall of the first connecting nut 3a is 120°, and a limit nut 4 is provided at the end of the screw 3b.

[0020] A movable claw hook 5 is passed through the middle of the screw rod 3b. Specifically, the movable claw hook 5 includes a ring 5a. The inner wall of the ring 5a is smooth and is passed through the screw rod 3b. A connecting rod 5b is provided at the bottom of the ring 5a. A groove 5c is provided at the side wall of the connecting rod 5b near the bottom. The force direction of the connecting rod 5b is consistent with the movement direction of the threaded push rod 2, and it is not easy to slip when used.

[0021] The utility model is easy to manufacture and can be used for daily standard parts processing.
