Preferably, described installing plate is fixed on by way of welding on the uncoupling rod bracket.
Preferably, described installing plate is platy structure.
The beneficial effects of the invention are as follows：Overall construction design of the present invention rationally, it is simple, be easy to make, using safety, can
Lean on, reequiped on existing car also easily, it is practical.The present invention on the screw rod of fixing bolt by setting upper and lower spiral shell
Line section, when the vehicle is running, the upper thread segment of fixing bolt is threadedly coupled with the screwed hole of installing plate, and its lower surface is pressed on car
On hook shadoof, anti-jump effect is good, effectively prevents uncoupling rod from producing improper displacement, it is to avoid the automatic uncoupling of vehicle coupler；When need
When operating uncoupling rod, rotating the fixing bolt makes lower thread segment be threadedly coupled with the screwed hole, and uncoupling rod is upward
Lift, it is possible to normal operating, it is easy to use, and connected between upper thread segment and lower thread segment by light bar segment, when need to
On when lifting uncoupling rod, only need to will be after upper thread segment unclamps, lifting fixing bolt, simplifies operating process upwards, saves
Operating time.
