Referring to fig. 16, two guiding members 18 are disposed at the bottom of the accommodating groove 11, the two guiding members 18 both extend along the height direction of the sleeve 10, the two guiding members 18 are disposed at intervals along the axial direction of the third rotating shaft 80, the two guiding members 18 respectively enclose the bottom of the accommodating groove 11 to form two guiding grooves 17 disposed at intervals along the axial direction of the third rotating shaft 80, and two ends of the third rotating shaft 80 are respectively slidably disposed in the two guiding grooves 17.

Referring to fig. 16, the guide members 18 include a first guide plate 181 and a second guide plate 182, the first guide plate 181 extends vertically from the bottom of the receiving slot 11, the second guide plate 182 extends from the first guide plate 181 in parallel with the bottom of the receiving slot 11, and the second guide plates 182 of the two guide members 18 are arranged in parallel and spaced apart.

Referring to fig. 18, the limiting structure 19 is disposed on one side of the second guide plate 182 facing the bottom of the accommodating groove 11, the limiting structure 19 includes two damping protrusions 191 disposed at an interval, a limiting groove 192 is formed between the two damping protrusions 191, when the third rotating shaft 80 slides to one of the damping protrusions 191, a user can push the third rotating shaft 80 with a slight force, so that the third rotating shaft 80 is limited to the limiting groove 192 through the damping protrusion 191, thereby supporting the stay 60 at a certain specific angle position, and when the supporting angle of the stay 60 needs to be adjusted, the user can push the third rotating shaft 80 with a slight force, so that the third rotating shaft 80 slides out of the limiting groove 192 through the other damping protrusion 191 and slides to the other limiting structure 19 along the guide groove 17.

Referring to fig. 18, the bottom of the receiving groove 11 is provided with a window 111 corresponding to the two guide grooves 17, so that the damping protrusion 191 is prevented from interfering with the bottom of the receiving groove 11, and a user can view the sliding position of the stay 60 through the window 111.

Referring to fig. 15, in order to adapt to the design of the two guiding members 18, a first engaging groove 215 is formed on a side of the supporting plate 21 facing the sleeve 10, and a second engaging groove 216 is formed between the two first engaging grooves 215, when the supporting plate 21 is received in the receiving groove 11, the supporting rod 60 is received in the second engaging groove 216, and the two guiding members 18 are received in the two second engaging grooves 216.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
