[0035] Working principle:

[0036] When the concrete mixer truck for building construction is used, when the worker needs to add concrete into the feeding hopper 5, if the worker stands on the left side of the feeding hopper 5, the left handle 14 is pulled outwards, at this time, the movement of the handle 14 can drive the movement of the left positioning rod 15, at this time, the left positioning rod 15 will be separated from the positioning groove 16 arranged in the left supporting plate 13, and the movement of the left handle 14 can drive the movement of the driving rod 10, at this time, the driving rod 10 will slide in the circular groove 9, the synchronous block 12 will slide in the synchronous groove 11, the movement of the two limiting round plates 17 can be driven synchronously by the movement of the driving rod 10, when the right limiting round plate 17 moves, the right positioning rod 15 and the right positioning groove 16 are separated, and then the worker rotates the handle 14, at this time, the rotation of the handle 14 can drive the rotation of the driving rod 10, the rotation of the supporting rod 8 can be driven by the rotation of the driving rod 10, and the rotation of the protective cover plate 7 can be driven by the rotation of the supporting rod 8, after the protective cover plate 7 is rotated by 180 degrees, the positioning of the protective cover plate 7 can be realized by inserting the positioning rod 15 into the positioning groove 16.

[0037] If the worker stands on the right side of the feeding hopper 5, the positioning rod 15 and the positioning groove 16 can be separated by pushing the handle 14, and then the handle 14 is rotated.

[0038] At the same time, the movement of the handle 14 can drive the deformation of the spring 19, so that the clamping of the positioning rod 15 and the positioning groove 16 is facilitated, and the rotation of the rotating ring 18 is facilitated under the cooperation of the spring 19 when the handle 14 is rotated.
