[0002] At present, polytetrafluoroethylene materials are particularly widely used among fluoroplastic materials. Pipes made of polytetrafluoroethylene materials have excellent chemical stability, high and low temperature resistance, corrosion resistance, flame retardancy, sealing, high lubrication and non-stickiness, electrical insulation and good anti-aging ability. When the fluoroplastic pipe is connected to the external pipe, the fluoroplastic pipe needs to be expanded. After searching, the patent with application number 201921540457.6 discloses a fluoroplastic pipe expansion device, including a base, a support plate is vertically fixedly connected to the rear side of the top of the base, and a cylinder is fixedly installed vertically downward in the middle position of the top of the support plate; a support column is vertically fixedly connected to the middle position of the top of the base, and the lower end of the piston rod of the cylinder and the top of the support column are fixedly sleeved with a plug-in sleeve.

[0003] However, during actual use, the applicant found that when expanding the fluoroplastic tube, the distance between the two struts was adjusted to expand the fluoroplastic tube. During this process, the fluoroplastic tube was only pulled in the upper and lower directions, resulting in uneven expansion of the fluoroplastic tube. In view of this, we propose a fluoroplastic tube expansion device. Utility Model Content
