Detailed Description
Referring to fig. 1 to 4, there is shown a specific structure of a preferred embodiment of the present invention, which includes a socket 10 and a lock nut 20.
The tube seat 10 comprises a main body 11, the main body 11 is provided with a mounting hole 101 for inserting the rod piece 30 and matching with the rod piece 30, a clamping part 12 extends out of an opening of the mounting hole 101, a limiting groove hole 102 for extending the elastic salient point 40 is formed in the side surface of the main body 11, the limiting groove hole 102 is communicated with the mounting hole 101, a convex part 13 is arranged beside the limiting groove hole 102, a guide groove 103 for guiding the elastic salient point 40 to enter the mounting hole 101 is formed in the inner side surface of the convex part 13, and the guide groove 103 is connected between one side of the limiting groove hole 102 and the mounting hole 101; in this embodiment, the socket 10 is made of plastic, the mounting hole 101 penetrates through the upper and lower end surfaces of the main body 11, the inner diameter of the lower end of the mounting hole 101 is smaller than that of the upper end, and the clamping portion 12 integrally extends from the lower end surface of the main body 11; the clamping portion 12 includes a plurality of clamping arms 121, the plurality of clamping arms 121 are arranged at intervals along the periphery of the opening of the mounting hole 101, and an external thread 122 is formed on the outer side surface of each clamping arm 121; the convex portion 13 is arc-shaped, and correspondingly, the guiding groove 103 is arc-shaped, and the convex portion 13 is located at a position close to the lower end of one side of the limiting groove hole 102.
