The invention discloses a synthesis method of a novel responsive amino modified polyether organic silicon surfactant. The method comprises the following steps: sequentially adding quantitative silicone oil with a high hydrogen content, D4, MM, and concentrated sulfuric acid into a reactor, starting a stirrer, heating to 50-60 DEG C, regulating the pH value of the product to 7.0 by using sodium carbonate after the required viscosity is reached, carrying out suction filtration by using a filter flask to obtain colorless transparent silicone oil with a low hydrogen content; adding quantitative PHMS, allyl glycidyl ether and an epoxy stabilizer into the reactor in sequence, introducing protective N2 into the reactor, starting the stirrer, raising the temperature to 80 DEG C, carrying out a reaction for 1 h at a constant temperature of 90 DEG C, then adding allyl polyoxyethylene acetate and chloroplatinic acid into the reactor, and carrying out a reaction until the mixture becomes transparent. Through a hydrosilylation reaction, allyl polyoxyethylene acetate and allyl glycidyl ether are introduced into a polysiloxane chain of hydrogen-containing silicone oil to prepare a modified polyether organic silicon intermediate, and the hydrophilicity is improved through the introduction of polyoxyethylene.

An electronic device includes a peripheral wall defining an opening, a frame defining an internal receiving space, a tray, a stopping piece, a button, and an elastic piece. The tray receives a storage device and is slidably received in the receiving space. The stopping piece is fixed between the opening and the frame. The stopping piece blocks the tray when the tray is wholly received in the receiving space. The button is connected to the stopping piece and configured to drive the stopping piece to release the tray when the button is pressed. The elastic piece pushes the tray to pass to be partly exposed out of the opening when the stopping piece releases the tray.
