The first spring 8 is sleeved on the outer side of the support frame 6. Tightening the fastening cap 7 can push the first spring 8 to press against the condensation plate 5, thereby enhancing the positioning and stabilization effect.

[0026] Furthermore, a positioning cap 11 is sleeved on the top end of the plate frame 3, a vertical axis 12 passes through the interior of the positioning cap 11, and the vertical axis 12 is fixed to the top end of the plate frame 3, a second spring 13 is sleeved on the outer side of the vertical axis 12, and the second spring 13 is located between the positioning cap 11 and the plate frame 3, and the plate frame 3 can be connected and assembled by passing the vertical axis 12 through the positioning cap 11.
