[0002] Sockets are often used to drive the driven parts to rotate, and can be replaced with different types of driven parts. They are often used to install / remove fasteners (such as bolts, screws and nuts) in processing plants. In actual use, sockets are used in conjunction with driving tools, such as combining with wrenches to increase the force arm to generate greater torque, and combining with power tools to save labor consumption.

[0044] The following are only examples to illustrate possible implementations of the present invention, but are not intended to limit the scope of protection of the present invention. The "one" or "at least one" preceding the nouns mentioned in the text does not limit the quantity, and it can also be "plural" according to needs. This change in quantity is also within the scope of protection, which is stated in advance.

[0045] Please refer to Figures 1 to 8 , which shows an embodiment of the utility model. The sleeve of the utility model includes: a main body 1 and a buffer ring 2.

[0046] The body 1 is defined in a circumferential direction 51, a radial direction 52 and an axial direction 53. The body 1 includes an outer wall 11 and a plurality of embedded grooves 12. The plurality of embedded grooves 12 are respectively recessed in the outer wall 11 along the radial direction 52. The plurality of embedded grooves 12 are arranged at intervals in the circumferential direction 51 to define a plurality of abutting portions 16. Any abutting portion 16 is between two embedded grooves 12 in the circumferential direction 51. The buffer ring 2 is sleeved on the outer wall 11 along the axial direction 53 to form a geometric polygon 3. The geometric polygon 3 includes a plurality of embedded portions 31 and a plurality of corner portions 32. The plurality of embedded portions 31 are embedded in the embedded grooves 12, and the plurality of corner portions 32 abut against the abutting portion 16. Each of the embedded portions 31 preferably protrudes out of the embedded groove 12 in the radial direction 52, so as to provide comprehensive protection in the circumferential direction 51.

[0047] In this embodiment, the outer contour of the cross-section of the buffer ring 2 is circular, which is convenient for disassembly and assembly to the main body 1; and the buffer ring 2 can be detached from the main body 1, which is convenient for replacement or choosing to only take the main body 1 for use; in addition, the main body 1 can also quickly identify the size and classify by assembling the buffer rings 2 of different colors.

[0048] When a collision occurs, the buffer ring 2 sleeved on the outer wall 11 can effectively absorb the impact force to protect the structural integrity of the main body 1. Moreover, when stored, the buffer ring 2 can keep adjacent objects away from the sleeve to reduce wear and collision.

[0049] It is worth mentioning that the buffer ring 2 is circular when not assembled on the outer wall 11. When the buffer ring 2 is sleeved on the outer wall 11, it will be deformed into the geometric polygon 3 due to the multiple embedded parts 31 and the multiple corner parts 32. When the sleeve falls, the structure of the geometric polygon 3 can not only absorb shock and buffer, but also effectively prevent the fallen sleeve from continuing to rotate and move, so that the user can quickly pick it up on the spot / nearby.

[0050] Preferably, the friction coefficient of the buffer ring 2 is greater than that of the body 1, so as to generate a greater resistance after falling to prevent the sleeve from rotating. In this embodiment, the buffer ring 2 is made of rubber and the body 1 is made of metal.

[0051] More specifically, the main body 1 is cylindrical, each of the embedded grooves 12 extends in a straight line, and each of the abutting portions 16 is arc-convex. In addition, the main body 1 further includes a set of connection holes 17 and a driving hole 18. The set of connection holes 17 is polygonal for the drive tool to be inserted, and the driving hole 18 is polygonal for the driven member to be inserted. The number of the plurality of embedded grooves 12 is equal to the number of the hole edges of the driving hole 18. The plurality of embedded grooves 12 are respectively parallel to the hole edges of the driving hole 18, so that the shape of the geometric polygon 3 is equal to the shape of the driving hole 18, so that the user can know the shape of the driving hole 18 by observing the shape of the geometric polygon 3. In this embodiment, the number of the plurality of embedded grooves 12 is four, and the four embedded grooves 12 define four abutting portions 16. When viewed along the axial direction 53, the extension of the four embedded grooves 12 is rectangular, and the four abutting portions 16 are rectangular corners.

[0052] More specifically, each of the embedded groove portions 12 includes a groove bottom wall 13 and two groove side walls 14. The two groove side walls 14 are respectively arranged on two opposite sides of the groove bottom wall 13 in the axial direction 53. Each of the groove side walls 14 and the groove bottom wall 13 is provided with an angle 15, and the angle of the angle 15 is not less than 90 degrees. The embedded portion 31 is respectively against the groove bottom wall 13 and the two groove side walls 14, whereby the embedded portion 31 can contact the embedded groove portion 12 in three different directions, thereby improving the combination stability of the embedded portion 31 and the embedded groove portion 12, so that the embedded portion 31 is not easy to separate from the embedded groove portion 12.

[0053] Preferably, the angle of the angle 15 is greater than 90 degrees, so that the embedding portion 31 forms two gap spaces 4 with the two groove side walls 14 on the two opposite sides in the axial direction 53, respectively. When the buffer ring 2 is to be removed, the user can use fingers or other components to reach into the gap space 4 to pull and hook the embedding portion 31 out of the embedding groove portion 12.

[0054] Finally, please refer to Fig. 9A sleeve of another embodiment includes: the main body 1A and the geometric polygon 3A. The main body 1A includes the outer side wall 11A, and the geometric polygon 3A integrally protrudes from the outer side wall 11A so that the two form a stepped configuration; wherein the sleeve can be integrally formed through various processing methods such as forging and turning. In this embodiment, the main body 1A is cylindrical, and the geometric polygon 3A is rectangular plate-shaped. The geometric polygon 3A includes a plurality of corner portions 32A and a plurality of connecting portions 33, and the connecting portion 33 is connected between two of the corner portions 32A, and the size of each corner portion 32A protruding from the outer side wall 11A is larger than the size of each connecting portion 33 protruding from the outer side wall 11A.
