[0029] A plurality of anti-slip protrusions 24 are integrally connected to one side of the support plate 21 facing the umbrella portion 3 .

[0030] The support portion 12 is integrally connected with a gripping portion 41 , and the gripping portion 41 is located between the support tube 22 and the connecting portion 11 ; the gripping portion 41 is spindle-shaped.

[0031] A placement groove 51 is provided at the upper end of the support portion 12, and the connection portion 11 is rotatably connected to the placement groove 51 through a pin shaft 53, and the axis of the pin shaft 53 is perpendicular to the axis of the support portion 12. A button 52 is slidably connected to the support portion 12, and a clamp is fixedly connected to the button 52. A positioning groove 54 is provided on the connection portion 11, and three positioning grooves 54 are distributed along the axis of the pin shaft 53. When the clamp is placed in the middle positioning groove 54, the connection portion 11 and the support portion 12 are coaxially arranged.

[0032] The button 52 is connected to the support portion 12 via a first elastic member, which is a spring. A pressing groove is formed on the outer wall of the button 52.

[0033] The button 52, the card block and the first elastic member are prior art and will not be described in detail in this embodiment.

[0034] A positioning hole 61 with a circular cross section is provided on the connecting portion 11, a positioning tube 62 is provided in the positioning hole 61, a second elastic member 63 is fixedly connected between the outer wall of the positioning tube 62 and the inner wall of the positioning hole 61, and a plurality of second elastic members 63 are evenly distributed along the axis of the positioning hole 61, and the pin 53 passes through the positioning tube 62 and the two ends of the pin 53 are fixedly connected to the supporting portion 12. Anti-slip components 7 are provided at both ends of the positioning tube 62 to prevent the second elastic member 63 and the positioning tube 62 from slipping out of the positioning hole 61.

[0035] The anti-drop assembly 7 includes a snap ring 71, a retaining ring 72, a mounting groove 73, and a spring piece 74. The snap ring 71 is fixed to the end of the positioning tube 62 and is used to contact the outer wall of the connecting portion 11. The snap ring 71 is integrated with the positioning tube 62, and the snap ring 71 and the positioning tube 62 are coaxially arranged. The mounting groove 73 is opened on the outer wall of the positioning tube 62 and is located at the end of the positioning tube 62 away from the snap ring 71.
