Of course, there are still many examples of the invention, wherein only details vary. Please refer to FIG. 7 , which is a second embodiment of the present invention. The main difference from the first embodiment is that the diameter of the large cylindrical portion 33 of the joint member 30 is 3/8 inch, while the diameter of the small cylindrical portion 34 is 3/8 inch. The diameter of the large cylindrical portion 43 of the joint member 40 is also 3/8 inch, and the diameter of the small cylindrical portion 44 is also 1/4 inch. Compared with the first embodiment, different specifications can be connected. other sleeves.

Please refer to FIG. 8 , which is a third embodiment of the present invention. The main difference from the first and second embodiments is that the second side surface 312 of the joint 30 is flat and not as large as the first and second embodiments. The cylindrical portion 33 and the small cylindrical portion 34; the second side surface 412 of the joint member 40 is flat without the large cylindrical portion 33 and the small cylindrical portion 34 of the first and second embodiments. The second side surface 312 or the second side surface 412 can also be directly attached to other sleeves of different specifications.

From the above description, it is not difficult to find that the present invention is characterized in that the dismantling tool 100 of the present invention has second side surfaces 312 and 412 through the joints 30 and 40 , and a large cylindrical portion extends from the second side surfaces 312 and 412 . 33, 43 and the small cylindrical parts 34, 44 are stepped and form the structure of the stepped surfaces 35, 45, so that the larger-sized sleeve 400 can be sleeved on the large cylindrical part 33 with its contact hole 401 and abut against the second The side surface 312 can also allow the socket 500 with a smaller size to be sleeved on the small cylindrical portion 44 with its contact hole 501 and abut against the step surface 45, or even the joint members 30 and 40 of the first, second and third embodiments can be mixed. In use, the same joints 30 and 40 can be used to share sockets of different specifications, so that the number of joints 30 and 40 required for the disassembly tool 100 is reduced. Compared with the conventional disassembly tool, the number of the above-mentioned embodiment can be reduced. Half of the number of the engaging parts 30 and 40 can effectively reduce the volume of the dismantling tool 100 , thereby achieving the effect of being convenient for storage and carrying.

The above-mentioned embodiments are only used to illustrate the present invention, but not to limit the scope of the present invention. All the modifications or changes that do not violate the spirit of the present invention belong to the intended protection category of the present invention.
