[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and transport gas. It is a driven fluid machine. Gas compression and gas transportation are machines that convert rotational mechanical energy into gas pressure energy and kinetic energy and transport the gas. Fans are mainly divided into two types: axial flow fans and centrifugal fans. Axial flow fans are widely used in various fields of industrial production due to their simple structure and easy installation.

During installation, the abutment seat 314 is slid into the corresponding abutment groove 214, and then the fastening screw 326 is rotated to drive the end cover tube 319 to move to the right, and then the moving seat 317 is driven to move to the right. Through the action of the hinged swing arm 2 318 and the swing arm 1 313, the three abutment seats 314 are driven to expand synchronously, and the inner walls of the abutment groove 214 are tightly abutted, so that the motor 3 can be quickly positioned and the coaxiality requirement of the motor 3 and the second mounting tube 2 is guaranteed. Then, the abutment seat 314 and the two ends of the abutment groove 214 are fixedly connected by a fixing device, thereby ensuring the stability of the motor 3 during use after the connection.

[0064] Then the second mounting tube 2 is placed in the first mounting tube 1, and in the process of moving downward, the positioning seat 411 and the positioning groove 412 are matched to limit the axial direction of the second mounting tube 2 and the first mounting tube 1 after being connected, and then the rotating shaft 429 is rotated to rotate, drive the eccentric wheel 430 to rotate, drive the mounting seat 426 to move upward, and then drive the connecting seat 424 to move upward, and then drive the connecting rods 423 at both ends to move upward, and at the same time drive the four sliding rods 1 420 to move upward, and under the action of the hinged swing arm 1 422 and the pressure plate 421, the pressure plate 421 is tightly pressed on the top surface of the connecting seat 211, and the radial direction of the second mounting tube 2 and the first mounting tube 1 after being connected is fixed, so that the connecting seat 211 and the connecting seat 112 are stably connected, and at the same time, the second mounting tube 2 and the first mounting tube 1 are stably connected, so that the motor 3 in the second mounting tube 2 can be conveniently and quickly maintained without disassembling the pipeline.

[0065] The present invention and its embodiments are described above, which is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it and do not deviate from the purpose of the invention, they can creatively design a structure and embodiment similar to the technical solution, which should fall within the protection scope of the present invention.
