[0033] The front and rear ends of the left side of the lifting plate 41 are fixedly connected to the two synchronous plates 43 respectively. The two synchronous plates 43 are set to be staggered, one long and the other short, so that when the two synchronous plates 43 drive the push plates 44 and the sliding plates 45 to move closer to each other, they are in a staggered moving state, thereby avoiding the two sliding plates 45 from colliding with each other when moving against each other to affect the effect of releasing the rotation restriction of the second rotating plate 25.

At the same time, the second rotating plate 25 contacts and squeezes the dislocation with the inclined surface of the sliding plate 45, so that the sliding plate 45 is dislocated to form a rotation restriction on the second rotating plate 25, thereby fixing the horizontal fixed component 3 and the nutrient licking bricks, so as to facilitate the linkage shielding adjustment of rainwater on the lower side.
[0035] The front and rear ends of the upper surface of the lifting plate 41 are respectively fixedly connected to two second fixing plates 46 set in an L shape, the two second fixing plates 46 are respectively fixedly connected to two third fixing plates 47, the two third fixing plates 47 are respectively connected to the clamping shafts fixed at the upper ends of the front and rear sides of the water receiving frame 48 through the fifth circular holes, the upper right ends of the front and rear sides of the water receiving frame 48 are respectively fixedly connected to two fifth fixing columns 491, the two fifth fixing columns 491 are respectively connected to the two sixth circular holes opened at the upper ends of the two reverse thrust plates 49, and the lower ends of the two reverse thrust plates 49 are respectively connected to the two ends of the third fixing column 27 through the seventh circular holes opened.
[0036] The operating steps of the utility model are:
[0037] The nutrition licking brick is placed on the rear pull-out column 31 on the fixing assembly 3 and is in contact with the rear push-up ring 311. Then the front pull-out column 31 is pushed to insert the threaded column 33 into the nutrition licking brick and threadedly connect with the spiral hole on the rear pull-out column 31. In this way, the front and rear push-up rings 311 can clamp and fix the nutrition licking brick.
