A displacement plate is fixedly mounted on the bottom of the connecting block, and a spraying module is arranged at the bottom of the displacement plate.

[0012] As a further description of the above technical solution:

[0013] The quick-release assembly includes a turntable and a travel rod, a power rod is fixedly installed on the outer wall of the turntable, a bidirectional threaded rod is fixedly installed on the other end of the power rod, the bidirectional threaded rod is rotatably installed on the bottom of the displacement plate through a bracket, and a threaded block is threadedly installed on the outer wall of the bidirectional threaded rod.
