The sleeve of the present invention is sleeved on a plug portion 71 of a driving tool 7, and the plug portion 71 is recessed at least. A positioning portion 72 includes a sleeve body 1, a switching member 2 and at least one positioning unit 3.

The sleeve body 1 is provided with an axis 11 and a working portion 12 disposed along the extending direction of the axis 11 and a set of connecting portions 13 for connecting a fastener (such as a screw, a bolt, a nut). The socket portion 13 is provided with a socket space 131 for inserting the socket portion 71. The switching member 2 is movable along the extending direction of the axis 11 and is rotatably disposed on the socket portion 13 .

In the present embodiment, in the direction parallel to the axis 11, the ratio of the length of the socket portion 13 to the length of the working portion 12 is between 0.4 and 0.6, in order to meet the appropriate size of the hand operation. Moreover, the switching member 2 is sleeved on the socket portion 13. The distance from the outer ring wall 25 of the switching member 2 to the axis 11 is substantially equal to the distance from the outer ring wall 25A of the working portion 12 to the axis 11. , but can have a more uniform size for storage. Of course, it can be changed according to requirements in other usage environments, and is not limited to the above.

The at least one positioning unit 3 includes a first receiving portion 31, a second receiving portion 32, and a positioning member 33. The first receiving portion 31 is disposed transversely to the axis 11 at the socket portion 13. The second portion The accommodating portion 33 is movably received in the first accommodating portion 31, and a portion of the locating member 33 protrudes from the first accommodating portion 31. In this embodiment, the positioning member 33 is rolled. The first receiving portion 31 and the second receiving portion 32 are respectively formed as through holes, and the second receiving portion 32 has a smaller aperture than the first receiving portion 31 to prevent the positioning member 33 from coming off. It can be understood that in other embodiments, the second portion can be a groove.

When the switching member 2 is in a locked position, the first receiving portion 31 and the second receiving portion 32 are offset from each other. In the direction of the axis 11 in the lateral direction, the switching member 2 covers the first receiving portion. The opening of the 31 is pressed against the positioning member 33. At this time, the switching member 2 forces a portion of the positioning member 33 to protrude from the socket space 131 for positioning with the positioning portion 72 to reach the sleeve. Connected to the plug portion 71 for the purpose. When the switching member 2 is in a releasing position, the first receiving portion 31 and the second receiving portion 32 completely overlap in the direction of the axis 11 in the lateral direction, so that when the positioning member 33 is received from the socket space 131 When the force is applied, a portion of the positioning member 33 can protrude into the second receiving portion 32 without protruding from the socket space 131. At this time, the positioning portion 72 is disengaged from the positioning member 33, and the insertion is allowed. The connecting portion 71 is pulled away from the socket space 131.

In this embodiment, the number of the at least one positioning portion 72 is two, and the positioning portion 72 is an opening that is symmetrically arranged and communicates with each other. The number of the at least one positioning unit 3 is two, and the positioning unit 3 is The axis 11 is symmetrically disposed at the center. When the switching member 2 is located at the locking position, the positioning members 33 are respectively embedded in the positioning portion 72.

Of course, the aspect of the insertion portion 71 and the positioning portion 72 is not limited thereto. For example, but not limited to, as shown in FIG. 6 and FIG. 7 , the insertion portion 71A is a tool post, and the positioning portion 72A is a recessed groove recessed in the insertion portion 71A. At this time, the sleeve can still be used by the positioning unit 3A in the plug portion 71A.

Referring to FIG. 1 to FIG. 5 again, it is worth mentioning that, since the switching member 2 can be rotated and axially moved relative to the sleeve body 1, the first volume can be increased by two different forms of motion cooperation. The dislocation of the second portion 32 is such that the switching member 2 is not accidentally moved to the release position by an unexpected external force, but must be manipulated by the user to accurately move to the release position. Therefore, the reliability of the sleeve being coupled to the insertion portion 71 for preventing loosening can be greatly improved.

Further, the sleeve further includes a limiting member 51, and the limiting member 51 is positioned on the socket portion 13 (in the embodiment, the limiting member 51 is fastened to the socket portion 13) The outer diameter of the working portion 12 is larger than the outer diameter of the socket portion 13 , and a first step portion 61 is formed at the junction between the working portion 12 and the socket portion 13 . The first step portion 61 is spaced apart from the limiting member 51 by a predetermined distance in the direction of the axis 11 , and the switching member 2 is limited between the first step portion 61 and the limiting member 51 . It can be understood that the predetermined distance is greater than the length of the switching member 2 in the direction parallel to the axis 11 so that the switching member 2 can slide in the direction of the axis 11.

Furthermore, the first abutting portion 21 and the second abutting portion 22 are disposed on opposite sides of the switching member 2, and the first abutting portion 21 is interposed between the second abutting portion 21 and the second abutting portion 22 The abutting portion 22 is between the first step portion 61. After the switching member 2 is rotated such that the first receiving portion 31 is disposed in line with the second receiving portion 32 in the direction parallel to the axis 11 , when the first abutting portion 21 abuts the first step portion 61 The switching member 2 is located at the release position, and when the second abutting portion 22 abuts the limiting member 51, the switching member 2 is located at the locking position.

It is to be noted that, in order to let the user know whether the first volume 31 and the second volume 32 are on the same line. A first indicator portion 41 is disposed on the sleeve body 1 . The first indicator portion 41 is opposite to the first axis portion 31 in the direction parallel to the axis 11 , and the second indicator portion 42 is disposed on the switch member 2 . The second indicator portion 42 is corresponding to the second housing portion 32 in the direction parallel to the axis 11 , and the user only needs to see whether the first indicator portion 41 is aligned with the second indicator portion 42 , which is very convenient.

Preferably, a second step portion 62 is further disposed on the sleeve portion 13. The base member 23 is further disposed on the switch member 2, and the two ends of an elastic member 53 abut the second step portion 62 and the base portion respectively. 23, further, the second abutting portion 22 has a tendency to approach the limiting member 51 in a normal state. In this way, when the external force is removed by the switching member 2, the switching member 2 can be quickly and automatically moved to the locking position, so that the sleeve can be quickly coupled to the insertion portion 71, and the rotation can be further rotated. The switching member 2 is such that the first receiving portion 31 and the second receiving portion 32 are not in the same straight line to improve the reliability of the anti-looseness. In addition to this, the elastic member 53 It can provide a certain supporting force to the switching member 2, so that it is less susceptible to being moved by an unexpected external force to increase stability.

In another preferred embodiment, the switching member 2 is further provided with a shielding portion 24, the shielding portion 24 is laterally connected to the second abutting portion 22, when the second abutting portion 22 abuts the limiting member 51, The blocking portion 24 covers the limiting member 51 in the direction of the axis 11 in the lateral direction to block the external object from contacting the limiting member 51. Thus, the structure of the limiting member 51 can be ensured to be stable and stable. It is located at the socket portion 13.

Similarly, the first abutting portion 21 is laterally connected to the base portion 23 and covers the second step portion 62. The first abutting portion 21, the base portion 23 and the socket portion 13 define an internal space 27 The elastic member 53 is accommodated in the internal space 27. In this way, the first abutting portion 21 can protect the structure and deformation of the elastic member 53 from external influences to ensure smooth movement of the switching member 2.

In another preferred embodiment, the switching member 2 is further provided with a non-slip structure 52 for pressing a finger 8 against the finger 8 to improve the stability of the switching member 2 and avoid slipping. Further preferably, the ring wall 25 is further provided with at least one recess 26 outside the switching member 2, and the second receiving portion 32 is disposed on the recess 26, and the finger 8 is pressed against the recess 26 to control the switching. In the case of the second part, the design of the recess 26 can increase the contact area between the switching member 2 and the finger portion 8, thereby improving stability. In this embodiment, the number of the at least one recess 26 is one and is a ring groove type.

In addition, two through holes 132 are formed in the socket portion 13 , and the through holes 132 are symmetrically arranged around the axis 11 to further provide different combinations. For example, but not limited to, when the second volume portion 32 of the through-hole type corresponds to the two through holes 132, the sleeve and the insertion portion 71 can be connected through the plug, or the sleeve can be It is also impossible for the cylinder to be positioned on the tool elevator by this means.

In summary, the sleeve of the present invention is simple in structure and simple in operation, and the user only needs to quickly insert the plug portion of the driving tool when rotating and moving the switching member to the release position. Moreover, as long as the finger is released, the elastic member can quickly push the switching member to move and the first and second portions are misaligned, and Hold in the locked position. In addition, the user can further rotate the switching member, so that the first receiving portion is more difficult to be driven by the external force and aligned with the overlapping second hole to increase the reliability of the anti-loose.
