[0034] A plurality of locking mechanisms are arranged inside the mounting plate 2, and a plurality of connecting channels 11 and a plurality of annular grooves 12 are opened inside the mounting plate 2, wherein the locking mechanisms, the connecting channels 11, the annular grooves 12 and the mounting holes 5 are arranged one by one, and the connecting channels 11 are connected to the mounting holes 5 through the annular grooves 12, and the annular grooves 12 are arranged coaxially with the mounting holes 5;

[0035] The locking mechanism includes a connecting frame 13, an annular frame 14 and a supporting spring 32; wherein the connecting frame 13 is movably arranged in the connecting channel 11, the annular frame 14 and the supporting spring 32 are both movably arranged inside the annular groove 12, and the supporting spring 32 is located below the annular frame 14, and the connecting frame 13 and the annular frame 14 are fixedly arranged; wherein an inclined portion 15 is formed on the annular frame 14, and the inclined portion 15 is used in conjunction with the convex portion on the wiring piece 10;

[0037] When the conductive post of the electron tube needs to be inserted into the mounting hole 5 in the mounting plate 2 so that the conductive post of the electron tube enters the interior of the terminal 6, the locking ring 3 is rotated according to actual needs so that the locking ring 3 presses the connecting frame 13. After the connecting frame 13 moves vertically in the connecting channel 11, the annular frame 14 is driven to press the supporting spring 32. At the same time, the inclined portion 15 on the annular frame 14 presses the convex portion on the terminal 6, so that the terminal 6 further strengthens the locking strength with the conductive post of the electron tube to avoid loosening.
