An umbrella base clamping mechanism of a sunshade comprises a sleeve, a threaded connector, a collet and a knob, the sleeve is vertically fixed to the middle of the upper end face of an umbrella base, the threaded connector is fixedly arranged at the upper end of the sleeve in a sleeving mode, a through hole allowing a lower section of the sunshade to be inserted is formed in the middle of the threaded connector, and the knob is arranged on the threaded connector in a sleeving mode and rotationally connected with the threaded connector through threads. The collet is of a conical clamping sleeve structure and is arranged in the rotary knob, the upper end of the collet is fixedly connected with the upper end of the rotary knob, the lower end of the collet is inserted into the through hole of the threaded connector, the inner wall of the upper portion of the through hole is a conical hole inclining downwards, and when the rotary knob is screwed clockwise and moves downwards, the collet moves downwards along with the rotary knob. And the conical surface of the collet is pressed against the conical hole of the screwed joint and is folded inwards to be clamped and locked with the lower section of the sunshade inserted into the sleeve. The device is simple and reasonable in structure and convenient to operate, stress on the lower section of the sunshade is more uniform through the collet, the sunshade is not prone to being damaged, positioning is stable, and safety and reliability are achieved.
一种遮阳伞的伞座夹紧机构，包括套管、螺纹接头、筒夹和旋钮，套管竖直固定在伞座上端面中间位置，螺纹接头固定套设在套管上端，螺纹接头中部开设有供遮阳伞下节插置的贯穿孔，旋钮套设在螺纹接头上、与螺纹接头通过螺纹转动连接，筒夹是锥形类夹套结构，筒夹设置在旋钮内，筒夹上端与旋钮的上端固定连接，筒夹下端插入螺纹接头的贯穿孔中，贯穿孔的上部内壁呈向下倾斜的锥形孔，当旋钮顺时针旋紧向下移动时，筒夹随之向下移动，筒夹的锥面与螺纹接头的锥形孔相抵挤压向内收拢与插入套管内的遮阳伞下节夹紧锁定。本发明结构简单合理、操作方便，通过筒夹对遮阳伞下节的受力更为均匀，不易损坏遮阳伞，定位稳定、安全可靠。
