Description

Technical Field

[0001] This utility model relates to the field of barbecue equipment technology, and in particular to a skewer driving mechanism and barbecue equipment. Background Technology

[0002] Chinese Patent CN201821542327 .1 discloses a rotating grill oven, including an oven body. The internal space of the oven body is divided into an upper rotating layer and a lower combustion chamber by a horizontally arranged partition. Two planetary gears are vertically arranged at intervals on the upper part of the rotating layer. The two planetary gears are arranged opposite each other and connected by a connecting rod between their sun gears. A skewer holder is fixedly arranged on the opposite surface of each planetary gear. The side wall of the skewer holder has a through hole, and a screw is threaded into the through hole. The skewer holder and the screw cooperate to form a threaded clamping mechanism. The side wall of each skewer holder on a planetary gear has a notch for inserting a skewer. The notch is offset from the axis of the screw. Tightening the screw causes one end of the screw to clamp the skewer against the inner wall of the skewer holder. The skewer holders on the two opposite planetary gears clamp the two ends of the skewer respectively. However, this skewer clamping structure is complicated to operate and requires users to spend a relatively long time clamping the skewer, which affects the user experience. Utility Model Content
