Each driving device 213 is used for driving the corresponding clamping portion 212 to approach or depart from the other clamping portion 212 along the first preset direction a. When each driving device 213 drives the corresponding clamping parts 212 to approach each other along the first preset direction a, the cable 200 can be clamped into the clamping grooves 2121 of the two clamping parts 212, and the clamping grooves 2121 of the two clamping parts 212 together define a clamping area for clamping the cable 200; when each driving device 213 drives the corresponding clamping portion 212 to move away from each other along the first preset direction a, the two clamping portions 212 can be separated from the cable 200 and the distance between the two clamping portions 212 in the first preset direction a is increased, so that a passing space is provided for the obstacle 300 suspended on the cable 200, and the obstacle 300 suspended on the cable 200 can pass through the space between the two clamping portions 212, thereby realizing obstacle crossing.
In the present embodiment, the driving device 213 is a driving structure capable of linearly driving the clamp, such as a linear motor, a hydraulic cylinder, and an air cylinder, provided at one end of the clamp arm 211 remote from the base 10.

Further, each of the clamp units 21 further includes a lock mechanism 214 for holding the clamp portion 212 in a clamped state. The locking mechanism 214 is provided to lock the clamping portion 212 and the cable 200 when the clamping portion 212 is in the clamped state, so as to hold the clamping portion 212 in the state of clamping the cable 200, so that the palm opening and closing device 100 can be stably suspended from the cable 200.
In the present embodiment, the locking mechanism 214 is configured to press the clamping portion 212 to deform the clamping portion 212 along the first predetermined direction a and maintain the clamping state. The locking mechanism 214 deforms the clamping portion 212 along the first preset direction a, so that the clamping portion 212 can tightly abut against the cable 200 in the first preset direction a, the locking effect is better, and the palm opening and closing device 100 can be more stably suspended on the cable 200.
