The processing module 202 is electrically connected to the pressure sensor 207. The change of the elastic force of the reset spring 2013 will cause the force exerted on the hydraulic oil to change. When the push rod 5 is reset and closed, the pressure sensor 207 detects that the pressure exerted on the hydraulic oil exceeds When it goes out of the preset range, the hydraulic oil pump 2015 will replenish the hydraulic oil in the airbag 2010, so that the force of the return spring 2013 is always within the applicable range.
