In order to solve the above-mentioned problem, in the prior art, an O-shaped sealing strip or a hardware elastic sheet is generally adopted to fix the PIN needle through frictional interference with the PIN needle so as not to fall.
However, in the practical use process, the O-shaped sealing strip is made of resin materials and is damaged after being inserted by long-time interference, so that the interference point is invalid and the PIN needle cannot be fixed.
The design principle of the hardware spring plate depends on the flexible principle of steel to enable the hardware spring plate to interfere with the PIN needle so that the hardware spring plate cannot fall off, but the toughness of the spring plate can be invalid after long-time plugging and unplugging to cause the interference point to weaken so that the PIN needle falls off.
Therefore, a new structure for preventing the PIN from falling needs to be designed.
