[0029] The following further describes the present application in detail with reference to the accompanying Figures 1-4 drawings.

[0030] An embodiment of the present application discloses a socket strip. Referring to Figure 1 , the socket strip includes a socket strip main body 1 and a connecting wire 2 connected to the socket strip main body 1. A protective member 3 is provided between the socket strip main body 1 and the connecting wire 2. The protective member 3 includes a protection part 31 and a connecting part 32 rotatably connected to the protection part 31. The connecting part 32 clamps the socket strip main body 1, and the protection part 31 is provided with a protection hole 33 for the connecting wire 2 to pass through.

[0031] Referring to Figure 2 , the protection part 31 includes a rotating cylinder 311, a rotating hemisphere 312 rotatably connected to the rotating cylinder 311, and a protective sleeve 313. One end of the rotating cylinder 311 is connected to the connecting part 32. A rotating groove 314 for the flexible rotation of the rotating hemisphere 312 is provided at the end of the rotating cylinder 311 away from the connecting part 32. One end of the rotating hemisphere 312 away from the rotating cylinder 311 is connected to the protective sleeve 313. The protection hole 33 penetrates through the rotating cylinder 311, the rotating hemisphere 312, and the protective sleeve 313. The rotating hemisphere 312 is a hollow hemisphere. The diameter of the opening at the end of the rotating groove 314 close to the protective sleeve 313 is larger than the diameter of the protection hole 33. An elastic member 315 is provided on the inner wall of the rotating hole 3116 where the protective sleeve 313 is located. The elastic member 315 includes the connecting wire 2. In this embodiment, the elastic member 315 is made of rubber with deformation ability, and the connecting member is further protected by the elastic member 315. In other embodiments, the elastic member 315 can also be other materials such as silica gel or sponge with deformation ability. The protection part 31 includes a rotating cylinder 311, a rotating hemisphere 312, and a protective sleeve 313. Through the rotational connection between the rotating hemisphere 312 and the rotating cylinder 311, the rotation at the connection between the connecting wire 2 and the socket strip main body 1 is transferred to between the rotating cylinder 311 and the rotating hemisphere 312, and the wear between the edge of the rotating hemisphere 312 and the connecting wire 2 is less, thereby reducing the wear of the connecting wire 2 and extending the service life of the socket strip.

[0032] Referring to Figure 3, the rotating cylinder 311 includes an upper rotating cylinder 3111 and a lower rotating cylinder 3112. A buckle 3113 is provided at the edge of the upper rotating cylinder 3111, and a slot 3114 for inserting the buckle 3113 is formed at the edge of the lower rotating cylinder 3112. The width of the slot 3114 is slightly smaller than the width of the buckle 3113, and the upper rotating cylinder 3111 and the lower rotating cylinder 3112 are in interference fit. When installing the rotating ball 312, first place the rotating ball 312 in the lower rotating cylinder 3112, and then buckle the upper rotating cylinder 3111 with the lower rotating cylinder 3112. Through the arrangement of the upper rotating cylinder 3111 and the lower rotating cylinder 3112, the installation of the rotating ball 312 is simple and convenient. In this embodiment, the upper rotating cylinder 3111 and the buckle 3113 are integrally formed. In other embodiments, the upper rotating cylinder 3111 and the buckle 3113 can also be connected by other methods such as thermal welding.

[0033] Refer to Figure 3 and Figure 4 , the connecting portion 32 includes a connecting piece 322 connected to the lower rotating cylinder 3112 and a mating piece 321 rotatably connected to the upper rotating cylinder 3111. The connecting piece 322 and the mating piece 321 jointly clamp the socket strip body 1. The connecting piece 322 is integrally formed with the lower rotating cylinder 3112.

[0034] The mating piece 321 includes a clamping portion 3211 for clamping the socket strip body 1, a connecting block 3212 connected to the clamping portion 3211, and a force-applying portion 3213 provided at one end of the connecting block 3212 away from the clamping portion 3211. The connecting block 3212 is rotatably connected to the upper rotating cylinder 3111. In this embodiment, the clamping portion 3211 and the connecting block 3212, and the connecting block 3212 and the force-applying portion 3213 are integrally formed.

[0035] Through the arrangement of the force-applying portion 3213, the mating piece 321 and the upper rotating cylinder 3111 form a lever model. Pressing the force-applying portion 3213 can make the clamping portion 3211 open and close up and down, so that the connecting portion 32 can be adapted to socket strip bodies 1 of different size specifications, thereby broadening the adaptation range of the protection member 3.

[0036] Refer to Figure 4, two rotating pieces 3115 are convexly provided on the outer periphery of the upper rotating cylinder 3111. A rotating shaft 4 is arranged between the rotating piece 3115 and the connecting block 3212. The rotating piece 3115 is provided with a rotating hole 3116 for the rotating shaft 4 to pass through, and the connecting block 3212 is provided with a through hole 3214 for the rotating shaft 4 to pass through. A torsion spring 5 is sleeved on the rotating shaft 4 to keep the matching piece 321 in a state of always clamping the socket main body 1. One end of the torsion spring 5 abuts against the outer peripheral surface of the upper rotating cylinder 3111, and the other end of the torsion spring 5 abuts against the side of the matching piece 321 close to the upper rotating cylinder 3111. Through the arrangement of the torsion spring 5, the matching piece 321 is always kept in a state of clamping the socket main body 1, thereby strengthening the connection between the protection member 3 and the socket main body 1 and making the connection between the protection member 3 and the socket main body 1 more stable.

[0037] The implementation principle of a socket in an embodiment of the present application is as follows: A protection member 3 is arranged between the socket main body 1 and the connecting wire 2. The protection member 3 includes a connecting portion 32 capable of clamping the socket main body 1 and a protection portion 31 connected to the connecting portion 32. The protection portion 31 includes a rotating cylinder 311, a rotating hemisphere 312 and a protection sleeve 313. By the rotational connection between the rotating cylinder 311 and the rotating hemisphere 312, the rotation locus of the connecting wire 2 is transferred, and the contact between the rotating hemisphere 312, the rotating cylinder 311 and the connecting wire 2 is less, reducing the wear of the protective layer of the connecting wire 2, thereby reducing the rupture of the protective layer, and further extending the service life of the socket.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application shall be covered within the protection scope of the present application.
