As shown in fig. 5, the vertical elastic metal sheet 2 and the pin 6 form a lever structure, the hinge joint of the two is a rotation pivot 61, the vertical elastic metal sheet 2 rotates along the radial direction of the pin 6, and the switching base 5 is provided with a notch 51 for the vertical elastic metal sheet 2 to rotate. The opposite sides of the two vertical elastic metal sheets 2 are provided with first positioning pins 3, the positions of the first positioning pins 3 are higher than or fall on a connecting line of the side locking point 11 and the rotating fulcrum 61 of the equipment 1, the parts, higher than the first positioning pins 3, of the upper parts of the two vertical elastic metal sheets 2 are bent outwards and extend to form unlocking parts 21, and the center position of the switching base 5 is provided with second positioning pins 4. When the pressure angle generated by the side locking point 11 of the equipment 1 to the vertical elastic metal sheet 2 is 90 degrees, the connecting line of the positioning pin I3, the side locking point 11 of the equipment 1 and the rotating fulcrum 61 is collinear with the connecting line of the side locking point 11 of the equipment 1 and the rotating fulcrum 61. The number of the first positioning pins 3 on the vertical elastic metal sheet 2 is at least two, and the number of the second positioning pins 4 is at least one. The fixing modes between the first positioning pin 3 and the vertical elastic metal sheet 2 and between the second positioning pin 4 and the switching base 5 comprise welding, screwing or riveting.
