The specific embodiment

As shown in Figure 1, the specific embodiment of the invention comprises headstock 1, arm sheet 2, connecting axle 3 and spring leaf 4, and headstock 1 has a room 11, and arm sheet 2 has a cam part 21, and cam part 21 places room 11 1 sides to wear pivot with connecting axle 3, wherein:

Room 11 bottom surfaces of headstock 1 are provided with stator 12 (before being assembling among Fig. 1/bending state not) as yet and stopping object 13;

Arm sheet 2 is provided with a fluting 22 in adjacency cam part 21 places;

Spring leaf 4 is a U matrix body, and spring leaf 4 has continuous but relative at interval an end and the other end, and wherein an end is a fixed part 41, and the other end is force section 42.

The present embodiment group immediately, (and readding Fig. 3) as shown in Figure 2, spring leaf 4 fits in room 11 bottom surfaces of headstock 1 with fixed part 41, the fluting 22 that force section 42 is through at arm sheet 2 presses on cam part 21, and be butted on fixed part 41 edges of spring leaf 4 with stopping object 13 correspondences of room 11 bottom surfaces, and fix to be pressed against another edge of fixed part 41 after stator 12 bendings.

According to the foregoing description, when hinge folded, then as shown in Figure 3, arm sheet 2 was taken in towards the room 11 of headstock 1, and can be contained in spring leaf 4 superjacent air spaces.
