Simple transformations made by persons of ordinary skill in the art based on the concept of the present invention should be within the scope of protection required by the present utility model.

The concept of the present invention and the working process under this concept will be described in detail below in conjunction with the accompanying drawings.

Embodiment: please refer to shown in Fig. 2 to Fig. 3, it is the perspective view to the exploded view of the preferred embodiment of the present utility model, can clearly find out that the utility model comprises from the figure:

a subject 1;

a plurality of combining parts 11 respectively formed at both ends of the main body 1, each of the combining parts 11 forming a pivot column 12;

a plurality of metal bases 2 respectively buried in the joint portion 11, and the two ends of the metal base 2 protrude from the joint portion 11; and

Several metal pins 3 are respectively pivoted on the metal base 2 .

A plurality of notches 13 are formed on the main body 1 for the pivotal movement of the metal pins 3, the notches 13 have a limiting surface 131 and a stopper 132, and the metal base 2 is in an L-shape, and the metal The pin 3 and the metal base 2 are combined by a riveting piece 4 .
