[0029] The specific implementation process of the utility model is as follows: when the delivery robot with good shock absorption effect needs to be used, the indicator light belt 10 is pushed to contact the vertical part of the large-area chassis 6, so that the insertion rod 11 is inserted into the vertical part of the large-area chassis 6. In this process, the end of the insertion rod 11 squeezes the horizontal part of the guide plate 12 to push the guide plate 12 downward, and the spring 14 is deformed, and finally the block 13 and the surface of the insertion rod 11 move. Under the action of force, the block 13 moves along the surface of the insertion rod 11. When the block 13 slides into the insertion hole on the surface of the insertion rod 11, the spring 14 restores the deformation to push the block 13 to insert the insertion rod 11, and the insertion rod 11 is limited, so that the insertion rod 11 drives the indicator light belt 10 to be placed stably, which is convenient for the operator to quickly disassemble and use;

[0030] The setting of the roller 2 facilitates the movement of the delivery robot. When the roller 2 encounters impact or vibration, the roller 2 pushes the telescopic rod 16 to move under the action of force, so that the telescopic rod 16 slides along the inside of the installation tube 15 and drives the fixed plate 17 to move. The shock-absorbing spring 18 is deformed to absorb and release the impact force, thereby avoiding the shaking problem of the accessory robot.

[0031] During this process, when the roller 2 moves, it can drive the fixed plate 20 to move, and the inner wall of the damping friction hole 19 squeezes the damping friction ball 22 to push the telescopic plate 21 to move, and drive the fixed plate 20 to move, and the elastic member 24 is deformed, and finally the damping friction ball 22 is separated from the base 1. Under the action of force, the damping friction ball 22 slides along the inner wall of the base 1. When the damping friction ball 22 slides into the next damping friction hole 19, the elastic member 24 restores the deformation to push the damping friction ball 22 to insert into the damping friction hole 19, and the cycle repeats. Under the action of the damping friction hole 19, the damping friction ball 22 and other structures, the excess deformation stress generated by the shock-absorbing spring 18 can be processed by friction loss to avoid the problem of excess shaking of the shock-absorbing spring 18.
