Specific embodiment
Please refer to figs. 1 to 4, that show the specific structures of the preferred embodiments of the invention, include tube socket
10, C clamp part 20, connecting rod 30 and swing pressure arm 40.
The tube socket 10 includes main body 11, and the 11 of the main body are with one for the insertion of rod piece 50 and peace compatible with rod piece 10
Hole 101 is filled, an end face of main body 11, which is integrally extended, multiple elastic clamp arm 12 and an anti-rotation salient point 13, multiple elasticity clamp arm
12 peripheries for surrounding mounting hole 101 are arranged, and are convexly equipped at least one elastic clamp arm 12 for carrying out axial limiting to C clamp part 20
Limiting section 102, which is located therein the outside of an elastic clamp arm 12.In the present embodiment, the multiple elasticity
Clamp arm 12 is integrally extended in the bottom face of main body 11, is offered inverted U-channel 103 in each elasticity clamp arm 12 and is formed with bullet
The tail end of piece 104, each elasticity clamp arm 12 is convexly equipped with limiting section 102, and each limiting section 102 is butted on the lower end of C clamp part 20
On face；The lower end surface of the main body 11 is radially expanded to extend restraining position ring block 14, which is butted on the upper end of C clamp part 20
On face；The elasticity clamp arm 12 is three, which is arc, and the width of the elastic slice 104 gradually increases from upper end to lower end
Greatly.
