[0030] Further, one end of the card block 8 is set as a right-angled triangle block, and the right-angled triangle block passes through the channel groove 11 and is slidably inserted into the card slot 10.

Figure 1 , Attachment Figure 5 and attached Figure 6 As shown, it is easy to control the device so as to achieve autonomous movement of the device.

[0034] Working principle: when the loading bar module 4 is needed, the bottom of the loading bar module 4 can be slidably sleeved on the outer surface of the limit slider 3. As the loading bar module 4 slides, when one side of the loading bar module 4 contacts the card block 8, the card block 8 is squeezed and slides back to the inside of the limit slider 3 along the channel groove 11, and the push block 7 is squeezed by the card block 8 and moves away from the strong magnetic block 9. The user can also pull the pull rod 26 to assist the push block 7 to move, and the reset spring 6 will be compressed. When the loading bar module 4 continues to slide until the channel groove 11 is aligned with the card slot 10, the card block 8 is no longer squeezed, and under the rebound effect of the reset spring 6 and the magnetic attraction of the strong magnetic block 9, the push block 7 moves closer to the strong magnetic block 9. The two groups of card blocks 8 move in the opposite direction, and the pushing block 7 pushes the two groups of card blocks 8 to move in the opposite direction. The two groups of card blocks 8 slide through the channel grooves 11 and are inserted into the two groups of channel grooves 11 respectively. The pushing block 7 and the strong magnetic block 9 attract each other with strong suction force, and the two will not be easily separated, so that the loading bar module 4 will not slide easily, so as to achieve the purpose of fixing the L-shaped vehicle body 1 and the loading bar module 4. If the loading bar module 4 is not needed, the pull rod 26 can be pulled to separate the pushing block 7 from the strong magnetic block 9, and the card block 8 is pulled by the pushing block 7, and the two groups of card blocks 8 move in the center. After the two groups of card blocks 8 are separated from the channel grooves 11, the loading bar module 4 is slid along the outer surface of the limit slider 3 until the loading bar module 4 is separated from the L-shaped vehicle body 1.

[0035] The L-shaped vehicle body 1 is equipped with a plurality of existing components to realize the following functions: pressing the power switch 22 can turn the power on and off, plugging an external charging cable into the charging socket 23 can charge the device, pressing the start button 17 can make the device work, rotating the delay start rotary button 18 can extend the time to start working, the LCD screen 19 can display working data, the metal keyboard 20 can input data instructions, pressing the emergency stop button 21 can shut down the device urgently, the driving signal light 24 can emit light when the device is working, the radar sensor 25 can detect the position and distance of obstacles, the radar sensor 25 will transmit the position and distance signal of the obstacle to the control system in the L-shaped vehicle body 1, the control system will transmit the signal to the driving system in the L-shaped vehicle body 1, and finally the L-shaped vehicle body 1 can stop moving or turn to avoid obstacles. The above are all existing mature technologies and will not be elaborated on here, thereby realizing the autonomous movement of the device;

[0036] If the collision rod 5 accidentally hits an obstacle, the impact force generated will be transmitted from the collision rod 5 to the screw sleeve 16, and then transmitted from the screw sleeve 16 to the second telescopic rod 15, so that the second telescopic rod 15 slides inside the first telescopic rod 13 and squeezes the buffer spring 14, and the impact force of the buffer spring 14 is buffered during the expansion and contraction of the buffer spring 14, so that the impact force will not cause too much impact on the material. If the collision rod 5 is damaged, the second telescopic rod 15 can be rotated to separate the second telescopic rod 15 from the screw sleeve 16, and then a new collision rod 5 and screw sleeve 16 are replaced, and the new screw sleeve 16 is threaded on the outer surface of the second telescopic rod 15. If the second telescopic rod 15 and the first telescopic rod 13 are damaged, the first telescopic rod 13 can be rotated to separate the first telescopic rod 13 from the screw rod 12, and the first telescopic rod 13 is threaded on the outer surface of the screw rod 12 after replacing the new first telescopic rod 13 and the second telescopic rod 15. The above is the entire working principle of the utility model.
