In the normally open state, and when the door panel 7 is opened to the position, the limiting post 414 will abut against the limiting block 37 to avoid excessive rotation. Referring to the first to fifth figures, when the door panel 7 is closed, the positioning post 422 can be smoothly raised obliquely by the arrangement of the guiding slope 413 and the sliding slope 423 (see FIG. 11). It is resisted to the surface of the rotating member 41.

Referring to the fourth, thirteenth and fourteenth drawings, it can be clearly seen from the fourth figure that the adjusting portion 522 of the positioning member 52 of the holding device 5 has a first length H1 to resist Rely on lock The head of the solid member 56 forms a fixed distance between the positioning member 52 and the pushing member 53, whereby the resetting ability of the elastic member 51 can be fixed, and if the resetting ability of the elastic member 51 is too large, the door panel 7 is closed less smoothly. Referring to the thirteenth and fourteenth drawings, the second length H2 or the third length H3 can be formed by using the adjusting portion (542, 552) by replacing the positioning member (54, 55). The space of the elastic member 51 is increased to lower the resetting ability. Furthermore, the hinge of the present invention can be installed in the left-hand and right-open manners of the door panel 7, so that the door panel 7 can be smoothly maintained in the open positioning state in the left or right opening, and the structure is simple and reliable, and the cost is low.
