[0024] In this embodiment, the pushing mechanism 4 can drive the two laser lamps 10 to swing at the same time, which can not only adjust the direction of the laser lamp 10, but also prevent the soil from contacting the laser lamp 10, with high safety. The two electric telescopic rods 42 are installed in opposite positions and distributed up and down, so as to avoid interfering with each other.

[0025] Specifically, a pair of long grooves 11 are formed on the top surface and the back surface of the second bucket body 2 , and a pair of sliding blocks 12 slidably connected to the long grooves 11 are welded to the upper inner wall and the back surface of the first bucket body 1 .

[0026] In this embodiment, the stability of the second bucket body 2 during sliding can be improved.

[0027] Specifically, the transmission mechanism 7 includes a pair of transmission sprockets 71, and a transmission chain 72 is connected between the two transmission sprockets 71. One of the transmission sprockets 71 is fixedly connected to one end of the telescopic long shaft 8, and the other transmission sprocket 71 is fixedly connected to the shaft of the protective shell 9.

The length of the entire loader bucket increases, and the capacity increases accordingly, and the work efficiency is greatly improved;

[0032] When the construction area is narrow (for example, the shoveled soil, sand, gravel, etc. are stored in a narrow place), the bucket of normal length is longer and the bucket is disturbed and cannot enter the narrow area.

Under the connection of the telescopic long shaft 8, the angles of the two laser lights 10 with protective shells 9 can be flexibly adjusted to illuminate the ground (or soil, sand, gravel, wall, etc.), and the position of the bucket can be determined in advance, which is convenient for the bucket to be quickly inserted into the narrow area.
