The top of described column can be connected at certain angle scope rotary type by a connection piece with aforesaid upper rack posts middle part, the middle part of described column is provided with the relative column locking mechanism of slippage up and down, and an end of this locking mechanism is then hinged with the lower end of aforementioned lower fulcrum bar.

As preferably, described locking mechanism comprises

Sliding sleeve, hollow can move up and down by opposed column outer wall, and described lower fulcrum bar then is articulated on this sliding sleeve; And

Be used for aforementioned sliding sleeve is positioned the nut that screws of described column outer wall, be located at aforementioned sliding sleeve one side revolvably.

For realizing packing up and to open, described column is provided with a hand-operated mechanism, and this hand-operated mechanism is connected with a stay cord, and this stay cord passes the column inner chamber and is connected by the pulley that is provided with in the column inner chamber and with aforesaid short umbrella rib disc.

As preferably, described hand-operated mechanism comprises

Shell is located at described column outer wall; And

Crank handle, inner end radially are arranged in described column and are connected with described stay cord, and the outer end then is the force side.

Described column bottom dismountable type is provided with an extension rod.Can prolong setting.

Compared with prior art, advantage of the present utility model is: be in the umbrella stand under the open mode, as long as locking mechanism slippage up and down, can realize angle adjustment fast, swift to operate, overall structure is simple relatively, easy to assembly again, again because column is in the state of a umbrella support all the time, so wind resistance is not affected.
