In order to meet the requirement of a user to splice a plurality of fans in a horizontal manner, fan manufacturers design fan frames. For example, taiwan TW M396884 and US2017/0331346 disclose a technical means for splicing fans via additional fixing members, and specifically, the fan frames are provided with coupling grooves or coupling members, and the coupling grooves and the coupling members are respectively provided with through holes for the fixing members to be disposed therein, so that when a user splices the fans, the coupling member on one of the fans is inserted into the coupling groove on the other fan, so that the through holes on the coupling member are aligned with the through holes on the coupling groove, and then the fixing members are inserted into the through holes, so that the fixing members limit the coupling member and the coupling groove. However, the splicing means of the fans relies on the position-limiting function provided by the fixing member, and once a user fails to use the fixing member when splicing the fans, the fans cannot be fixed and are easy to move. In addition, the conventional fixing member is an independent component, and generally, the size of the fixing member is significantly smaller than that of the fans, so that the fixing member is easily lost during the storage process, which causes inconvenience to users.

To improve the above problems, fan manufacturers have changed to splice the fans without using additional fasteners, as disclosed in US10,690,336B and chinese CN 101725571B. For us US10,690,336B, the fans have slots or positioning blocks on their fan frames, so that when a user splices the fans, the positioning blocks of one fan are connected to the slots of another fan, so that the fans form an assembly relationship. However, the conventional solution of directly forming the mechanical connection structure on the fan is prone to cause the misalignment of the mechanical connection structure due to the excessive dimensional tolerance between the fans. Moreover, the conventional fan has a certain gesture when being assembled or disassembled, which causes the complex disassembly and assembly of the conventional fan and is inconvenient for users.
