Locking structure for banana canopy sunshade

Abstract

A locking structure for a banana canopy sunshade is specifically provided, and belongs to the field of banana canopy sunshades. The locking structure for the banana canopy sunshade is assembled on an adjustment sleeve. By cooperation between the insertion rod and the crank, the locking structure for the banana canopy sunshade solves the following problem: During adjustment of a height of the existing banana canopy sunshade on a support rod, a bolt needs to be used to fix the banana canopy sunshade on the support rod. As a result, it is more tedious in the adjustment of the banana canopy sunshade on the support rod, the operating intensity of a user is increased, and the operating efficiency is affected.
