The creative department provides an improved cupper structure.It is mainly composed of a main cupping cup and an extended cupping cup.The main cupping cup does not need to be separated from the air extraction device to replace the cupping cups of different sizes.The main cup body can be disassembled and assembled in series according to the requirements and different sizes of the extended cupping cup.The air density of each cup is connected with each other.In addition to adjusting and improving the absorption strength of cupping,The adsorption area of the extended cupping cup can be increased by the opening of the adsorption interface of the cupping cup.And then make this creation to achieve the convenience of cupping.本創作係提供一種拔罐器結構改良，其主要係藉由一主拔罐杯及一延伸拔罐杯所相對構組而成；本創作藉由該主拔罐杯不需自抽氣裝置拆離更換不同尺寸的拔罐杯，而可因需求與不同尺寸大小延伸拔罐杯之作拆卸串聯組裝主杯體，並令各杯體氣密相互連通，除可調整增進拔罐的吸附強度外，藉由該延伸拔罐杯之吸附接口呈喇叭開口形態更可增進其吸附面積，進而使本創作達到拔罐使用的便利之實用進步性者。
