Abstract

A roller device comprises a roller body of a roller. The roller body of the roller is wholly of a cylindrical structure, the roller body of the roller is formed by integrally injecting a roller end, a roller cylinder and a roller tail body, and the roller end is composed of a first outer threaded opening section, a circular truncated cone section and a cylindrical section. One end of the smaller side of the circular truncated cone section is connected with the first outer threaded opening section, the other end of the circular truncated cone section is connected with the cylindrical section, the roller tail body is provided with a second outer threaded opening section, and the bottom of the second outer threaded opening section extends to form a cuboid-shaped sheet body. In this way, the defects that the roller is not beneficial to construction, and execution of the roller is not firm when a connecting part shakes are effectively overcome.
