In order to dissipate this heat and ensure the normal operation of electronic components, the industry uses fans to cool electronic components. Traditional fans generally include a stator, a rotor, and a frame that houses the stator and rotor. The rotor usually includes a hub and several fan blades that are evenly arranged around the hub and radiate outward. In the existing technology, two cooling fans are connected and fixed to achieve series connection between the fans. However, the existing cooling fan series assembly has technical problems such as inconvenient connection structure and low assembly efficiency. Utility Model Content

[0003] The purpose of this invention is to provide an adjustable telescopic series cooling fan, which aims to solve the technical problem that the assembly of existing cooling fans is not simple enough.

[0004] To achieve the above objectives, this utility model provides an adjustable telescopic tandem cooling fan, including a mounting bracket, a drive device, fan blades, and several connecting members. Two sliding grooves are provided on each of the two non-adjacent sides of the mounting bracket. The two sliding grooves on the same side are located at opposite ends of the side, and one end of each sliding groove connects to the end of the side. The connecting members are partially slidably disposed within the sliding grooves. The drive device is fixedly mounted on the mounting bracket, and the fan blades are fixedly mounted on the rotating end of the drive device.
