The present invention relates to a holding device of a belt wheel structure, including two arm plates, and a connecting member. Each arm plate is pivoted with the connecting member by a locking member. Each arm plate has a first end provided with a fixing snap, and a second end pivoted with a movable snap by a securing member. Each movable snap has a base portion screwed with the securing member, thereby positioning and locking the movable snap on the respective arm plate. The fixing snap is protruded with a snap tooth, and each movable snap is laterally protruded with a snap tooth, so that the snap tooth of the fixing snap may mate with the snap tooth of each movable snap to be inserted into a belt wheel structure for holding and securing the belt wheel structure.
