Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
Embodiment:
As shown in Figures 1 to 5, the mirror pin without screw structural that the present embodiment provides, comprise mirror leg and the picture frame Connection Element 6 being connected with mirror leg, described mirror leg connectivity port is provided with breach 1, described breach 1 comprises the first breach 2, the contiguous block 3 of the second breach 4 and separation the first breach and the second breach, the width of the first described breach 2 is greater than the width of the second breach 4, i.e. the first breach 2, contiguous block 3, the second breach 4 forms trapezoidal shape, metal installation sheet spring 5 is installed on described breach 1, metal installation sheet spring 5 one end are arranged on and are placed in the first breach 2, other end buckle is on the second breach 4, it is the first round end 10 of bending structure and the second round end 11 that described metal installation sheet spring 5 two ends are provided with one-body molded with metal installation sheet spring, the described free end portion 20 that is positioned at the second round end of the second breach is placed on the end face 4 of contiguous block and the termination 21 of free end portion and the end face of contiguous block 4 are conflicted, second round end of buckle in the second breach 4 and the inwall of the second breach leave gap 5, the size of described gap 5 is basic identical with the lateral separation size that is placed in the free end portion 20 on contiguous block, described picture frame Connection Element 6 is arranged in the first breach 2, the first round end 10 that metal installation sheet spring 5 is positioned at the first breach is fastened and connected with picture frame Connection Element 6, in figure dotted portion label for " 5 " and be to be the structural representation of metal installation sheet spring buckling state, can press free end portion 20 moves to gap, the second round end 11 5 can be moved toward gap, cause the second round end 11 is left to the second breach 4, mirror pin and picture frame Connection Element 6 can be separated.
