In one embodiment of the present invention, the hood hinge rotating arm 2 includes an upper rotating portion 2a and a lower fixing portion 2b, and the rotating portion is disposed on a base end side of the hood hinge rotating arm 2 and is bolted to the hood hinge fixing base 1 by the pin 3.

As an embodiment of the present invention, the number of the pins 3 is two or more, and the two or more are respectively called a first pin, a second pin, and an nth pin.

As an embodiment of the present invention, the hood hinge rotating arm fixing portion 2b is provided at a distal end side of the hood hinge rotating arm 2 and is bolt-fixed to the hood through a mounting hole 6. The rotating part 2a of the engine cover hinge rotating arm is also provided with a mounting hole 6, so that the engine cover hinge rotating arm 2 can be fixedly connected to an engine cover through bolts.

As an embodiment of the present invention, the hood hinge fixing base 1 and the hood hinge rotating arm 2 are hinged by the pin 3, and the rotating portion 2a of the hood hinge rotating arm is hinged to the hood hinge fixing base 1 and forms a rotating axis, so that the hood hinge rotating arm can rotate around the rotating axis relative to the hood hinge fixing base 1.

As a preferred embodiment of the present invention, one end of the hood hinge rotating arm 2 hinged to the hood hinge fixing base 1 may be hook-shaped. Further, the connecting edge of the hood hinge rotating arm fixing portion 2b and the hood hinge rotating arm rotating portion 2a are fixedly connected through a first pin, and the connecting edge of the hood hinge rotating arm fixing portion 2b may further include a movable groove.

In one embodiment of the present invention, the small flip part 4 is fixedly and detachably attached below the hood hinge rotating arm 2 on the same side as the hood hinge fixing base 1.

As shown in fig. 3, the small spread member 4 has an L-shaped side cross section, and the bend of the L-shape divides the small spread member into a small spread first member 4a and a small spread second member 4 b. One end of the small-sweep first member 4a is connected to the hood hinge rotating arm 2 at a base end thereof close to the hood hinge rotating arm rotating part 2a, and the distance from the apex of the rear edge arc 5 of the hood hinge fixing base 1 to the horizontal straight line of the small-sweep second member 4b is smaller than the length of the small-sweep second member 4 b.
