The traction device comprises a positive and negative pressure device, a Luer connector and a separable traction line, the separable traction line further comprises a silica gel suction cup, a silica gel tube and a conical head which are sequentially connected, the separable traction line is the silica gel tube, the shore hardness of the separable traction line is 40-60 degrees, and the shore hardness of the separable traction line is 40-60 degrees. The inner surface area of the silica gel suction cup is divided into a frosted surface and a smooth surface, the frosted surface area is arranged on the side, close to the tail end of the silica gel suction cup, of the inner side wall of the silica gel suction cup, and the smooth surface area is adjacent to the frosted area. The observation angle of the capsule endoscope can be freely controlled, the defects that the capsule endoscope stays in the esophagus for a short time, the omission ratio is low, the observation angle is single, assembly is tedious, and disas
