Description

TECHNICAL FIELD

[0001] The utility model relates to a chafing dish technical field, especially in a novel manual lifting chafing dish. BACKGROUND

[0002] A lifting chafing dish is disclosed in Chinese patent document No. CN213605793U on July 6, 2021, which comprises a pot body, a basket and a lifting mechanism. The pot body is provided with a cooking space and a storage space separated from each other. The basket is arranged in the cooking space in a lifting manner. The lifting mechanism comprises a lifting support, a jacking piece and a shifting piece. The lifting support is rotatably arranged in the storage space. The upper end of the jacking piece abuts against the basket, and the lower end of the jacking piece abuts against the lifting support. When the lifting support rotates, it can drive the jacking piece to lift or lower the basket. The shifting piece is connected to the lifting support to drive the rotation of the lifting support. The lifting chafing dish can drive the rotation of the lifting support by pushing the shifting piece, thereby driving the jacking piece to lift or lower. When the jacking piece rises, it can lift the basket, so that the basket rises. When the jacking piece descends, the basket also descends because the upper end of the jacking piece abuts against the basket. However, the shifting piece is horizontally pushed, which may drive the entire lifting chafing dish to rotate horizontally, resulting in the failure to lift or lower the basket.

[0003] Therefore, it is necessary to make further improvements. CONTENT OF THE UTILITY MODEL
