When the upper hinge base 2 slides relative to the hinge body 1 to the proximal end of the guide groove 12 in the direction away from the hinge body 1, since the first protruding arm 21 is an elastic arm, the elastic force of the first protruding arm 21 can make the first hinge pin 211 cross the stopper strip 13 and enter the clamping area 14, so that the first hinge pin 211 is fixed at the proximal end of the guide groove 12, the hinge assembly is kept at the position of the opening state, and the first hinge pin 211 can rotate around the axis of the first hinge pin 211 when being in the clamping area 14. Similarly, when the lower hinge base 3 slides to the proximal end of the guide groove 12 in the direction away from the hinge body 1 relative to the hinge body 1, since the second protruding arm 31 is an elastic arm, the elastic force of the second protruding arm 31 can make the second hinge pin 311 cross the stopper 13 and enter the engagement area 14, so that the second hinge pin 311 is fixed at the proximal end of the guide groove 12, the hinge assembly is kept at the open position, and the second hinge pin 311 can rotate around the axis of the second hinge pin 311 when in the engagement area 14.

As shown in fig. 11 and 12, in the present embodiment, the first hinge pin 211 and the second hinge pin 311 are a cylinder, and the axial direction of the cylinder is perpendicular to the first protruding arm 21 or the second protruding arm 31, however, in other embodiments, the first hinge pin 211 and the second hinge pin 311 may have other structures, such as a block, without departing from the scope of the present invention.

arms

21 and 31 is sufficiently large, and otherwise is not caught in the guide groove 12, whereas in the present case, since one end of the guide groove 12 is opened, the installation problem of the first and second protruding

arms

21 and 31 is not considered, so that the groove depth of the guide groove 12 can be made deeper, and the lengths of the first and second hinge pins 211 and 311 are also made longer, the elasticity of the first and second protruding

arms

21 and 31 can be made smaller, and when the lengths of the first and second hinge pins 211 and 311 are sufficiently long, the elastic force of the first and second protruding

arms

21 and 31 is smaller, the first hinge pin 211 and the second hinge pin 311 can be effectively prevented from being removed from the guide groove 12, thereby increasing the utility of the hinge assembly.

As shown in fig. 13 and 15, when the first hinge pin 211 is at the proximal end of the guide groove 12, the distance H of the body of the upper hinge base 2 with respect to the hinge main body 1 is greater than the thickness W of the first projecting arm 21, where the body of the upper hinge base 2 is the upper hinge base body 22, and, when the second hinge pin 311 is at the proximal end of the guide groove 12 with respect to the lower hinge base 3, the distance of the body of the lower hinge base 3 with respect to the hinge main body 1 is greater than the thickness of the second projecting arm 31, and the body of the lower hinge base 3 is the lower hinge base body 32.
