Under the action of the tension spring, the tension spring pulls the movable block 6, the support frame 7 and the sealing cap 8 to move to the left until the limiting strip 10 is movably connected to the limiting frame 9. At this time, the position of the sealing cap 8 does not affect the operator's use of the coupler body 3, and at the same time, the loss of the sealing cap 8 is avoided. And when using the sealing cap 8 next time, similarly adjust the sealing cap 8 to rotate by 180 degrees to seal the coupler body 3.
