Alternatively, as shown in fig. 11-13 and 16, the motor bracket 12 is provided with a first opening 91, the motor cover 5 is provided with a second opening 92, and the first opening 91 and the second opening 92 form a through hole 9 for the motor shaft 41 of the motor 4 to pass through; the motor bracket 12 is provided with a limiting rib at the first opening 91, and/or the motor cover 5 is provided with a limiting rib 8 at the second opening 92 to limit the movement of the motor 4 along the axial direction of the motor shaft 41.

A through hole 9 surrounded by the first opening 91 and the second opening 92 at the same end of the motor 4 is used for enabling a motor shaft 41 of the motor 4 to extend out of the motor bracket 12 and the motor gland 5 in the left-right direction (namely the Y-axis direction in fig. 13) so as to facilitate the connection and matching of the motor shaft 41 of the motor 4 and the wind wheel; the limiting rib 8 is in a semicircular prismatic structure and is matched with the shape of the first opening 91 or the second opening 92; the limiting ribs 8 are convexly arranged on the motor support 12 and/or the motor gland 5 and positioned at the end part of the motor 4, and are used for limiting the motor 4 to move along the axis direction of the motor shaft 41 (namely, the Y-axis direction in fig. 13) so as to avoid the damage of the connection fit between the motor shaft 41 and the wind wheel caused by the movement of the motor 4 along the axis direction of the motor shaft 41 and ensure the stability of the motor 4 in the wind pipe machine.

Furthermore, preferably, the motor bracket 12 and the motor gland 5 are both provided with a limiting rib 8 to further enhance the limiting effect of the motor bracket 12 and the motor gland 5 on the motor 4 in the axial direction of the motor shaft 41; specifically, spacing muscle 8 on the motor gland 5 sets up the both ends that are located 41 axial directions of motor shaft at motor gland 5, spacing muscle 8 on the motor support 12 sets up the both ends that are located 41 axial directions of motor shaft at motor support 12, wherein, spacing muscle 8 on the first support 121 sets up the one side that deviates from second support 122 at first support 121, spacing muscle 8 on the second support 122 sets up the one side that deviates from first support 121 at second support 122, thus, in order to reduce the occupation space of motor support 12 and motor gland 5 in the tuber pipe machine, in order to avoid spacing muscle 8 on the first support 121 and spacing muscle 8 on the second support 122 to set up too closely and lead to motor support 12 and motor gland 5 to have the bigger condition emergence that is used for holding motor 4 of size in 41 axial directions of motor shaft.
