As shown in fig. 2, 4 and 5, the suction rod 10 includes a negative pressure cylinder 14 fixedly disposed on the circuit board 0, a piston head 15 is disposed inside the negative pressure cylinder 14, a vertical telescopic tube 16 is disposed at the top of the piston head 15, the telescopic tube 16 passes through a guide cylinder 17 at the top of the negative pressure cylinder 14 and extends out of the negative pressure cylinder 14, and a suction cup 18 matched with the suction head 13 is disposed at the upper end of the telescopic tube. The guide cylinder 17 and the negative pressure cylinder 14 are of an integral structure and are integrally formed, in order to improve the sealing property between the telescopic pipe 16 and the guide cylinder 17, a groove facing the telescopic pipe 16 is formed in the inner surface of the upper end of the guide cylinder 17, and a sealing ring 27 is sleeved at the groove.
A side hole 19 is arranged on the side wall of the lower end of the extension tube 16, and the inner cavity of the negative pressure cylinder 14 at the upper part of the piston head 15 is communicated with the tube hole of the extension tube 16 through the side hole 19. The side of the bottom of the negative pressure cylinder 14 is also provided with a one-way exhaust assembly for exhausting gas in the negative pressure cylinder 14 below the piston head 15, the simplest one-way exhaust assembly is an exhaust port arranged on the negative pressure cylinder 14, the end part of the exhaust port is provided with an elastic membrane plug, when internal gas is exhausted, the elastic membrane can be pushed open to realize exhaust, and when external gas enters, the elastic membrane is tightly pressed on the exhaust port to realize plugging, so that one-way communication is formed.

Before the piston head 15 completely reaches the bottom of the negative pressure cylinder 14, a certain amount of gas is still arranged below the piston head 15, so that a certain resilience force is generated, and a prompt effect is also realized to remind an operator of improper insertion. However, as the insertion proceeds, as shown in fig. 3, the gas in the lower section of the negative pressure cylinder 14 is completely exhausted, and the connector 11 is also completely inserted into the interface body 9, at this time, since the bottom surface of the piston head 15 is tightly attached to the bottom surface of the negative pressure cylinder 14 and there is substantially no gas therebetween, the piston head 15 can be tightly attached to the bottom surface of the negative pressure cylinder 14 and no longer rebounds, thereby reminding the operator of the proper insertion.
