[0035] When the pressure plate 206 applies pressure to the electrical equipment, the electrical equipment will generate an upward reaction force, which will drive the pressure plate 206 to move upward in the oil cylinder 205, and then push the hydraulic oil inside the oil cylinder 205 into the fixed bins 212 on both sides through the oil pipe, driving the piston plate 213 in the fixed bin 212 to move downward, driving the upper wedge block 214 to move downward and squeeze each other with the lower wedge block 215, driving the lower wedge block 215 to drive the top plate 216 to move toward the side of the electrical equipment, and then driving the two top plates 216 to apply a certain clamping force to the two sides of the electrical equipment.
