Specific implementation mode
The utility model is described in detail below with reference to attached drawing and in conjunction with the embodiments.It should be noted that not rushing
In the case of prominent, the features in the embodiments and the embodiments of the present application can be combined with each other.
In the description of the present invention, it should be understood that the orientation of the instructions such as term " opposite side ", "inner", "outside"
Or position relationship is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of description the utility model and simplification is retouched
It states, does not indicate or imply the indicated device or element must have a particular orientation, with specific azimuth configuration and operation,
Therefore it should not be understood as limiting the present invention.
Fig. 1 shows the utility model spring transmission turning device part schematic diagram.Spring transmission turning device as shown in Figure 1
Including two identical connectors 101, above-mentioned two connector 101 by interconnection 103 structure of pipe 102 and polygonal nut
At, preferably, above-mentioned polygonal nut 103 is hexagonal, and 102 opposed side openings 104 of pipe of two connectors 101, pipe
102 borings make to form an object placing cavity in pipe 102, pin shaft hole 105 and bolt hole are also provided on above-mentioned pipe 102
106, and pin shaft hole 105 and bolt hole 106 are opened and are worn on 102 two opposite outer walls of pipe, it is fixed between two connectors 101
There are spring and reinforcement spring 110, wherein spring to be made of inner spring 107 and the outer spring 108 being socketed in outside inner spring 107,
The rotation direction of thread of inner spring 107 and outer spring 108 is oppositely arranged, and the both ends of inside and outside spring are respectively provided at two connections
In the pipe 102 of part 101, and the two corresponding pin shaft holes 105 and bullet on 101 pipe 102 of connector are passed through by axis pin 109
