The housing base 21 has an outer shell 211 and an inner shell 212 disposed inside the outer shell 211 . The inner shell 212 has a shell body 213, a locking member 214 movably disposed on the shell body 213, and a second elastic member 215 disposed between the shell body 213 and the locking member 214, The housing body 213 is provided with a locking slot 216 for the second mounting plate 22 to be locked. The locking member 214 can move relative to the housing body 213 in a locking position and a non-locking position. position, the second mounting plate 22 can be clamped in the card slot 216 and fixed on the inner shell 212 by the clamping member 214, and in the non-clamping position, the second mounting plate 22 can be moved away from the inner shell In the shell 212 , the second elastic member 215 always pushes the engaging member 214 to the engaging position, thereby the second mounting plate 22 is detachably fixed on the inner shell 212 . The inner shell 212 can move relative to the outer shell 211, the fixing unit 2 also includes two fasteners 23 that can adjust and fix the inner shell 212 in the outer shell 211, and a detachable set on the outer shell 211 The decorative panel 24 outside and covering the fastener 23 .

The pivot unit 3 pivotally connects the movable part 1 to the fixed unit 2, and includes a pivot plate 31, a link 32, and a casing 211 that pivotally connects the link 32 to the fixed unit 2 A first supporting shaft 34 near the side of the movable member 1 and a first elastic member 33 . One end of the pivot plate 31 is pivotally connected to the movable part 1, and the other end of the pivot plate 31 is pivotally connected to the housing base 21, so that the movable part 1 can rotate in an open position and a closed position relative to the fixed unit 2 In the open position, compared with the closed position, the angle formed by the first mounting plate 11 and the second mounting plate 21 is larger, and one end of the first elastic member 33 abuts against the first supporting shaft 34, the other end is against the pivot plate 31, and when the movable part 1 moves to the closed position, an elastic force is provided to keep the movable part 1 in the closed position, and the linking part 32 has a A first end 321 pivotally connected to one side of the first shaft 34 and a second end 322 on the other side of the first shaft 34. The second end portion 322 of the linking member 32 defines a limiting groove 5 .

The buffer unit 4 is arranged in the accommodating space 20, and includes a follower 41 pivotally connected to the second end 322 of the linkage 32, and a follower 41 pivotally connected to the fixing unit. 2's second pivot 44, and a pressure assembly 42 pivotally connected to the follower 41. The follower 41 has a third end 411 pivotally connected to the second end 322 , and a fourth end 412 pivotally connected to the pressure component 42 . The second supporting shaft 44 , the third end portion 411 and the fourth end portion 412 can be substantially connected to form a triangle.
