Detailed description of the invention
In order to explain technical scheme of the present invention further, below by specific embodiment, the present invention will be described in detail.
As shown in Figures 1 to 6, it is a kind of umbrella rib type rotary pressing mechanism 100 that the present invention relates to, and wherein, comprises holder 1, screw rod 2, Mobile base 3, multiple hinge seat 4 and multiple pressing plate 5, wherein:
This holder 1, middle part has screw 11;
This screw rod 2, has bar portion 21 and head 22, and this head 22 diameter is greater than bar portion 21, this bar portion 21 and holder 1 screw 11 threaded engagement, and screw rod 2 can be moved up and down relative to holder 1;
This Mobile base 3, is set in bar portion 21, and between head 22 and holder 1; Concrete, be also provided with separation pad 9 between this Mobile base 3 and holder 1, this separation pad 9 is also set in the bar portion 21 of screw rod 2;
