[0029] At least one guide rail 200 and a driving member 300 arranged on the guide rail 200 are arranged on the base 100. The driving member 300 can drive the cutting module to move on the guide rail 200 for cutting. At the same time, a conductive structure 500 is arranged on the guide rail 200, and the conductive structure 500 can transmit current, control signals, etc., so that when the cutting module slides on the guide rail 200, the controller 900 can control the cutting module to perform cutting work through the conductive structure 500 without using wires.

[0036] The guide rail 200 may be made of insulating material, such as plastic, etc. When the guide rail 200 is made of insulating material, the conductive strip group 510 may be directly disposed on the guide rail 200. When the guide rail 200 is made of metal material, the insulation problem between the guide rail 200 and the conductive strip group 510 needs to be considered.

At the same time, the driving member 300 drives the sliding seat 410 to slide along the guide rail 200, thereby adjusting the trimming positions of the first blade 430 and the second blade 440 to complete the trimming task. The trimming is achieved by driving the first blade 430 and the second blade 440 to move, which has a simple structure and is easy to implement.

[0050] By providing a first guide rail 210, a second guide rail 220 and a third guide rail 230, the first driving member can drive the second guide rail 220 to move along the first guide rail 210, the second driving member can drive the third guide rail 230 to move along the second guide rail 220, and the third driving member can drive the cutting module to move along the third guide rail 230. The first guide rail 210, the second guide rail 220 and the third guide rail 230 are not parallel to each other, providing three moving dimensions, so that the position of the cutting module can be flexibly adjusted to meet the trimming requirements of the green wall.

In normal use, the contraction force of the spring keeps the friction member and the wheel of the universal wheel separated; an external force drives the friction member to move, and since the spring deforms the most when it is located at the rotation center of the friction member, when the spring passes the rotation center of the friction member, the spring begins to contract and the contraction force of the spring drives the friction member to keep in contact with the wheel of the universal wheel, and then the friction between the friction member and the wheel of the universal wheel restricts the rotation of the wheel of the universal wheel, that is, it is in a locked state. An external force drives the friction member to move, causing the spring to reset and pass the rotation center of the friction member again to unlock.
