Detailed Description

The following detailed description of embodiments of the present invention is made with reference to the accompanying drawings.

The utility model comprises a U-shaped plate 1 with a downward opening, a rectangular plate 2 is arranged below the U-shaped plate 1, a plurality of vertical first vertical rods 3 are arranged at the upper end of the rectangular plate 2, a plurality of second vertical rods 4 corresponding to the first vertical rods 3 one by one are arranged in the U-shaped plate 1, the first vertical rods 3 are eccentrically arranged with the corresponding second vertical rods 4, the upper end of the first vertical rod 3 is hinged with a horizontal connecting rod 5, the other end of the connecting rod 5 is hinged with the second vertical rods 4, and the rectangular plate 2, the U-shaped plate 1, the plurality of first vertical rods 3, the second vertical rods 4 and the connecting rod 5 form a parallelogram structure; the U-shaped plate 1 is internally provided with a worm 6 which is arranged along the front-back direction and can rotate, one side of the worm 6 is meshed with a horizontal worm wheel 7, the worm wheel 7 rotates to be fixed on the U-shaped plate 1, the rectangular plate 2 is provided with a vertical pin 8, the upper end of the pin 8 is hinged with the worm wheel 7, and the pin 8 is not coaxial with the worm wheel 7.

In order to realize the rotation of the worm 6, two ends of the worm 6 penetrate through the side plates of the U-shaped plate 1 and are arranged outside the U-shaped plate 1, a small gear 9 is fixed at the end part of the worm 6, a plurality of wheels are arranged on the front side plate and the rear side plate of the U-shaped plate 1, a large gear 10 which is coaxially fixed is arranged on each wheel, and the large gear 10 is meshed with the small gear 9.

In order to ensure that the axes of the rectangular plate 2 and the duct piece are kept parallel when the duct piece is leveled, the outer sides of the front side plate and the rear side plate of the U-shaped plate 1 are provided with horizontal flat plates 11, the lower side of one end, far away from the U-shaped plate 1, of each flat plate 11 is provided with a vertical plate 12, and the front side and the rear side of a grinding tool can be clamped by the two vertical plates 12 for limiting.

It is worth noting that the outer edge of the rectangular plate 2 can be designed to be of an upturned structure, and the phenomenon that concrete is scattered when the rectangular plate 2 is at a concrete accumulation position can be effectively prevented.
