[0002] With the rapid development of science and technology, the construction industry has gradually evolved from manual brick carrying to automated brick transportation. Brick-carrying machines play a significant role in the construction industry, reducing manpower and increasing the efficiency of brick loading.

[0003] For example, patent application number CN202110082789.X discloses a brick-holding clamping mechanism, including a clamping plate top cover and two sets of clamping arm assemblies respectively located on the left and right sides of the clamping plate top cover. A support frame is provided below the clamping plate top cover, and the middle part of the clamping arm assembly is mounted on the support frame through a pin. A hydraulic cylinder is provided on the clamping plate top cover, and the front and rear ends of the hydraulic cylinder are respectively connected to the top of the clamping arm assemblies on both sides. A clamping arm baffle is provided on the lower half of the clamping arm assembly, and a movable clamping plate that can be rotated around the bottom end of the clamping arm assembly is provided at the bottom of the clamping arm assembly. The hydraulic cylinder drives the clamping arm assembly to rotate around the pin to perform the brick-holding action.
