fig. 2 is a schematic structural diagram of the transition sleeve of the present invention.

In the figure, 1-transition sleeve, 2-bolt, 3-opening and 4-threaded hole.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail through the accompanying drawings and embodiments. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

Referring to fig. 1, an embodiment of the utility model provides a pneumatic tool twists rings transition device, its characterized in that: the transition sleeve comprises a transition sleeve 1 and a bolt 2, wherein the top of the transition sleeve 1 is rigidly connected with the threaded end of the bolt 2, and a plurality of groups of axially symmetrical openings 3 are arranged at the lower part of the transition sleeve 1.

In a possible embodiment, the top of the transition sleeve 1 is provided with a threaded hole 4, the inner diameter of the threaded hole 4 is matched with the outer diameter of the threaded end of the bolt 2, and the depth of the threaded hole 4 is smaller than the length of the threaded part of the bolt 2; the transition sleeve 1 and the bolt 2 are connected through threads and then welded and fixed.
