[0029] In the embodiment: by arranging the connecting assembly 5, when the public head shell 1 and the female head shell 2 are connected, the connecting ring block 4 of the female head shell 2 is inserted into the connecting ring groove 3 of the public head shell 1, in the inserting process, the connecting block 504 will extrude the clamping block 501 in the connecting ring groove 3, the clamping block 501 will move away from the side of the connecting block 504 under the pressure of the connecting block 504, when the connecting block 504 is completely inserted into the connecting ring groove 3, the clamping block 501 will be clamped into the inside of the clamping groove 505, so that the public head shell 1 and the female head shell 2 are firmly connected, when it is needed to separate the public head shell 1 and the female head shell 2, the lifting block 11 on the moving rod 502 is pulled, the moving rod 502 drives the clamping block 501 to move towards the inside of the public head shell 1, so that the clamping block 501 is separated from the clamping groove 505, at this time, since the clamping block 501 is no longer limited by the clamping groove 505, the female head shell 2 can be taken off from the public head shell 1, so that the convenience in connection is improved.

[0030] Specifically, as shown in Figure 3 , Figure 6 , the inside of the public head shell 1 is provided with an annular groove 8, and the shielding shell 601 is movably connected in the annular groove 8.

[0031] Specifically, as shown in Figure 3 , Figure 6 , the top and the bottom of the inner wall of the annular groove 8 are provided with mounting grooves 9, the inside of the top mounting groove 9 is rotatably connected with a screw rod 602, the surface of the screw rod 602 is threadedly connected with a threaded block 603, and the threaded block 603 is fixedly connected to the top of the shielding shell 601.
