Abstract: The present disclosure provides an adsorption structure. The adsorption structure includes an adsorption member, a negative pressure mechanism, a starting mechanism and a release mechanism. The adsorption member is used for adsorbing other objects. A first cavity provided with an opening is formed in the adsorption member. The opening of the first cavity is used for forming a sealing structure with surfaces of other objects. The negative pressure mechanism is provided with a second cavity for generating a negative pressure, and the second cavity is communicated with the first cavity. The starting mechanism, is used for starting the negative pressure mechanism. The release mechanism is used for balancing a pressure intensity in the first cavity and an atmospheric pressure to enable the adsorption member to release an adsorbed object.
