ABSTRACT:
A striding shank fixing device includes an insert tube, a guide tube, and an adjusting member. The guide tube has plural position holes, and the adjusting member has a hole for the guide tube to pass through and a position projection to fit in one of the position holes to secure the adjusting member with the guide tube at an adjusted location. A thumb screw screws through the adjusting member to press a driving strip to push forcefully against a vertical side of a wall to secure the shank fixing device striding on the wall so the shank of a parasol may be inserted in the insert tube and stabilized by a thumb screw screwing through the insert tube and pressing against a driving block in the insert tube and pressing against the shank to support the parasol stably.
