Abstract: Disclosed are a pressure coupling hydraulic hybrid power driving circuit and a control method therefor, and an excavator. The pressure coupling hydraulic hybrid power driving circuit comprises a three-way pressure matcher, wherein a first external oil port of the three-way pressure matcher is connected to a first oil port of an actuator element; a second oil port of the three-way pressure matcher and a second external oil port of the actuator element are connected to a hydraulic pump and an oil tank via control valves; and a third oil port of the three-way pressure matcher is connected to an oil port of an energy accumulator. The pressure and the flow at the oil port of the three-way pressure matcher meet the following pressure coupling relationships: (PA1±△P)q1＝P2•q2+PX•q3 and q1＝q2+q3. By adjusting P2 and q2, the function of the energy accumulator as an auxiliary power source cannot be lost due to the change in a load pressure PA1 of the actuator element, and the problems, in the prior art of hybrid power, that the pressure of a hydraulic pump, the load pressure of an actuator element and the hydraulic oil pressure of an energy accumulator are difficult to match, and that energy-saving operation thereof is difficult are thus solved.

Abstract: Safety scissors, comprising two blades (1) which are pivotably connected, the sides of the two blades facing each other are hollows (11), edges (10) of the blades are located at the sides of the blades corresponding to the hollows, and an angle a between a cutting face (12) of each blade and a reference plane (2) perpendicular to a rotation centerline of the blade is less than 90 degrees. The position of the edge of the blade is changed, so as to ensure that the angle a between the cutting face of the blade and the reference plane is less than 90 degrees, so that the position of the edge is not located at upper and lower edges of the blade. In this way, it is equivalent to increasing the angle of the blade, which is usually greater than 90 degrees, and when a finger (5) touches the edge, the pressure of the blade is smaller than that in the prior art, and as the edge is not located at the upper and lower edges of the blade, it is not easy for the finger to touch the edge on the front side. Therefore, the risk of a user being cut can be reduced, and the safety is greatly improved compared with existing scissors.
