When it is necessary to install the upper housing 3 or the lower housing 2, the user can snap the convex ring 4 on the upper housing 3 or the lower housing 2 into the interior of the snap ring 5 to position the upper housing 3 or the lower housing 2. Fastening bolts 6 extending into the interior of the convex ring 4 are installed on both sides of the antenna body 1. Both the upper housing 3 and the lower housing 2 are detachably connected to the antenna body 1. The fastening bolts 6 can install the upper housing 3 and the lower housing 2 on the antenna body 1 and can seal the antenna body 1.

[0038] Referring to Figures 1-4 , an installation platform 7 is installed inside the antenna body 1. A plurality of installation holes 8 are provided on the installation platform 7. The provision of the plurality of installation holes 8 facilitates the installation of micro medical device components. A toroidal body 10 is installed below the interior of the lower housing 2. A transfer member 11 is provided on one side of the toroidal body 10. The transfer member 11 is an arc-shaped conductive metal sheet. The transfer member 11 is in contact with the inner wall of the lower housing 2. Since the transfer member 11 is a conductive metal sheet, it can conduct electricity. The contact between the transfer member 11 and the inner wall of the lower housing 2 can improve the stability of the transfer member 11. And a bent portion 15 is provided at the top of the transfer member 11. The provision of the toroidal body 10 facilitates the installation of the transfer member 11. A metal cylinder 13 is installed at the top of the toroidal body 10. And a conductive column 14 is provided at the top of the metal cylinder 13. The provision of the conductive column 14 can conduct electricity. A positioning groove 12 is provided on one side of the top of the lower housing 2. The bent portion 15 is located inside the positioning groove 12. The provision of the positioning groove 12 facilitates the bent portion 15 to be stuck inside it to position the bent portion 15.

[0039] Specifically, the pressure relief component 9 includes a cavity 902 formed above the interior of the upper housing 3 and a plurality of pressure relief holes 901. Above the interior of the cavity 902, a plurality of springs 903 are installed, and the bottom end of the spring 903 is connected to a piston 905. The thickness of the piston 905 is greater than the diameter of the pressure relief hole 901. When the air pressure inside the antenna body 1 increases due to temperature rise, the piston 905 is pushed upward by the air pressure and compresses the spring 903, causing the spring 903 to be compressed. A ventilation hole 904 is formed at the bottom of the cavity 902. When the piston 905 moves upward and no longer blocks the pressure relief hole 901, the gas inside the antenna body 1 can enter the pressure relief hole 901, thereby achieving the purpose of pressure relief and heat dissipation. The piston 905 is slidably connected to the cavity 902, and the outer wall of the piston 905 fits against the inner wall of the cavity 902, so that the piston 905 can slide inside the cavity 902 and improve the stability of the piston 905 during movement.

[0040] Embodiment 2:

[0041] Based on the above Embodiment 1, in order to prevent hydraulic fluid from entering the antenna body 1 through the pressure relief hole 901, the following structure is provided.

[0042] Refer to Figure 1 、 Figure 2 and Figure 5 , a waterproof and breathable membrane 906 is installed at the top of the pressure relief hole 901, so that gas can be discharged through the waterproof and breathable membrane 906, while liquid cannot enter the pressure relief hole 901 through the waterproof and breathable membrane 906.

[0043] The working principle of the present utility model is as follows: First, when the lower housing 2 and the upper housing 3 need to be installed on the antenna body 1, first snap the convex ring 4 into the snap ring 5 to position the upper housing 3 or the lower housing 2. At the same time, the bent portion 15 is snapped into the positioning groove 12 on the lower housing 2. Then, screw the fastening bolt 6 into the convex ring 4 to fix the upper housing 2 and the lower housing 3. In this way, the installation of the antenna body 1 with the lower housing 3 and the upper housing 2 can be completed;

[0044] When the components inside the antenna main body 1 work, heat will be generated. As the temperature rises, the air pressure inside the antenna main body 1 will increase. The piston 905 will move upward under the push of the air pressure and compress the spring 903. When the piston 905 moves upward and no longer blocks the pressure relief hole 901, the gas inside the antenna main body 1 can enter the interior of the pressure relief hole 901 and be discharged through the waterproof breathable membrane 906, so as to achieve the purpose of pressure relief and heat dissipation, prevent the heat inside the antenna main body 1 from being too high and accelerate the damage speed of the components. At the same time, after the pressure relief is completed, the spring 903 stretches and then pushes the piston 905 to move downward and reset, so that the piston 905 blocks the pressure relief hole 901, avoiding the interior of the antenna main body 1 from communicating with the outside through the pressure relief hole 901. The setting of the waterproof breathable membrane 906 allows the gas to pass through and prevents the liquid from seeping into the pressure relief hole 901.
