Patent attributes
The present invention relates to a locking device for retaining one end part of a horizontal bar. The locking device includes a housing and a retaining block. The housing has an inclined groove defining a closed end and an open end, and the open end is above the closed end so that the end part of the horizontal bar is able to be rested in the closed end of the inclined groove of the housing. The retaining block is rotatable with respect to the housing between a first position where the retaining block is located in the inclined groove for retaining the end part of the horizontal bar, and a second position where the retaining block is moved out of the inclined groove for allowing the end part of the horizontal bar to be removed from the housing.
