Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
The present embodiment is only explanation to the utility model, is not the limitation to the utility model, this field skill
Art personnel can as needed make the present embodiment the modification of no creative contribution after this specification is read, but as long as
It is all protected in the right of the utility model by Patent Law.
Embodiment 1：As shown in Figure 1, Figure 2 and Figure 3, a kind of brake shaft coupling of clothes airing machine is shown, including cylindrical shape
Fixed seat 1, be set in fixed seat 1 for connect driving shaft main connection 2, for connect driven shaft from connector 3 and
Torsional spring 4.Fixed seat 1 is fixed on the stent 8 in clothes hanger host, one end of main connection 2 it is cylindrical and in fixed seat 1
Wall is adapted to, and is adapted to from 3 side of connector for cylindrical surface and with the inner wall of fixed seat 1.
The notch 21 that main connection 2 is equipped with, the section of notch 21 are cyclic annular in fan.Torsional spring 4 is socketed on main connection 2,
The inward at both ends of torsional spring 4 is bent to form hook 41 and two hooks 41 are positioned in interior notch 21；Torsional spring 4 connects according to own resilient tensioning
It touches in 1 inner wall of fixed seat；There is pivoted arm 31 of the section in fan annular from one end of connector 3 is axially extending, pivoted arm 31 extends to notch
In 21 and positioned at two hooks 41 between, main connection 2 and offer to carry out circumferential direction to transmission shaft from the axle center of connector 3
The axis hole of limiting.The cross sectional shape of axis hole can be arbitrary graphic than circular, in order to easy to process general using simple
Geometric figure.In the present embodiment the section of 2 upper shaft hole of main connection be in semicircle shape, for motor axis connection, from connector 3
Upper shaft hole section is in long waist shaped, for the wheel axis connection with reel.
Torsional spring 4 is in, along its axial float, the side wall of main connection 2 is equipped with to be turned round for accommodating in fixed seat 1 in order to prevent
