The first advantageous point of the present invention is explained by the following:

before the work begins, the retraction block 21 is extended out, the retraction block spring 22 is in a normal state, the extension pipe 26 is retracted inside the extension base pipe 25, the extension pipe spring 27 is in a compressed state, when the extension pipe spring is connected with a driving connection end of a double-drive draught fan of an automobile, the draught fan drives a connection rod to enter the inside of the connection buckle through groove 12 through the abutting buckle through groove 29, and the connection rod is connected and fixed through the fixing block after passing through the connection buckle through groove 12;
