A lift frame 4 is arranged near the RF heads 2 on the frame 1; six ball grooves are arranged inside the RF mother sockets 3, and steel balls 5 are arranged inside the ball grooves. Extrusion rings 6 are slidably connected to the RF mother sockets 3 near the steel balls 5, and movable grooves 7 are arranged on the inner walls of the extrusion rings 6. Fixed grooves 8 are arranged on the outer surfaces of the bottoms of the RF heads 2, and the movable grooves 7 and the fixed grooves 8 are matched with the steel balls 5. The four extrusion rings 6 are fixedly connected through connecting plates 9, and the RF mother sockets 3 are fixedly connected to the frame 1; telescopic mechanisms 10 for synchronously controlling the extrusion rings 6 are arranged on both sides of the bottom of the connecting plates 9; and the lift frame 4 is provided with a clamping mechanism 11 for quickly taking and placing the RF heads 2 near the RF heads 2.

[0024] It should be noted that the user clamps the RF head 2 inside the lifting frame 4 through the locking mechanism 11, and then controls the connecting plate 9 to move downward through the telescopic mechanism 10. The connecting plate 9 moves while driving the extrusion ring 6, so that the movable groove 7 on the extrusion ring 6 moves to the ball groove, increasing the moving range of the steel ball 5, and then controls the lifting frame 4 to move downward. The lifting frame 4 moves downward while driving the RF head 2, so that the RF head 2 is inserted into the inside of the RF mother socket 3, and then controls the connecting plate 9 to move upward through the telescopic mechanism 10. The connecting plate 9 drives the extrusion ring 6, so that the extrusion ring 6 squeezes the steel ball 5, and then a small part of the steel ball 5 moves to the inside of the fixing groove 8, thereby achieving the purpose of fixing the connection between the RF head 2 and the RF mother socket 3, and realizing the docking and fixing of the RF head 2 and the RF mother socket 3, improving the stability of the connection between the RF head 2 and the RF mother socket 3, and solving the problem that the current communication base station test docking device can be moved for docking, but because the docking point has no fixed function, the connection is relatively unstable, which easily leads to poor model transmission performance.

When the RF head 2 completely enters the U-shaped groove 14, the spring 17 generates elastic recovery to push the limiting bead 16. The limiting bead 16 fixes the RF head 2 through the U-shaped groove 14 on the lifting frame 4. When the RF head 2 needs to be taken out, just pull the RF head 2 toward the outside of the U-shaped groove 14 with force.
