The invention can quickly install the transmission shaft sleeve 7 and the transmission shaft rod 6 by arranging the transmission connecting shaft sleeve and the transmission shaft rod 6 and then arranging the locking buckle 62 which is quickly installed on the transmission shaft rod 6, particularly, when the installation is carried out, firstly, the inserting block 61 is rotated to the state that the position of the avoiding groove 602 corresponds to the inserting rod 611 and corresponds to the limiting locking groove 601, the transmission shaft sleeve 7 is inserted into the groove of the axis of the fan 51, when the insertion is in place, the transmission shaft sleeve 7 is rotated to ensure that the transmission block 71 arranged on the transmission shaft sleeve 7 corresponds to the groove opening of the transmission locking groove 501, then, the transmission shaft rod 6 is inserted, in the insertion process, the connecting block below the transmission block 71 corresponds to the groove opening of the limiting locking groove 601, the locking buckle 62 is continuously inserted inwards, namely, the locking buckle 62 is gradually squeezed, so that the locking buckle 62 is pushed against the connecting block 711, then, the connecting block 711 is inserted into the transmission locking groove 501501, and then continuously inserted until the locking buckle 62 penetrates through the transmission shaft sleeve 7, and then the insertion block 61 is pulled, so that the insertion block 61 drives the insertion rod 611 to be pulled out of the insertion slot 603, then the locking buckle 62 is not extruded by the insertion rod 611, when the locking buckle passes through, under the elastic force of the third elastic element 6211, the locking buckle 62 is ejected and abuts against the side wall on the transmission shaft sleeve 7, after the insertion block 61 is pulled out, so that the protruding fixed stop block 612 is inserted into the locking buckle 62, and then the locking buckle 62 is abutted, that is, the connection tightness between the locking buckle 62 and the transmission shaft sleeve 7 can be further improved.
When the fan 51 needs to be cleaned, the fan 51 can be quickly detached, specifically, when detaching is performed, the insertion block 61 is directly pulled out outwards, the insertion block 61 drives the insertion rod 611 to be pulled out, then the insertion block 61 is rotated until the insertion rod 611 corresponds to the notch of the slot 603, the avoidance groove 602 at this time is located at the notch position of the limiting locking groove 601, then the insertion rod 611 is inserted into the slot 603 under the elastic force of the second elastic piece 6131 and then abutted to the inclined surface 621 formed on the limiting buckle 62, then the pressing is performed directly, in the process that the insertion rod 611 abuts to the inclined surface 621, the inclined surface 621 is gradually squeezed, so that the locking buckle 62 moves along the squeezing direction of the inclined surface 621, namely, the insertion rod 611 contracts into the transmission shaft lever 6, and then the fan 51 can be directly pulled out to clean the fan 51.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
