Wherein, at least one clamping mechanism 20 is movably arranged on the frame 10 along a first direction. Each clamping mechanism 20 is capable of clamping or releasing the pull-cord 200. Specifically, the hauling rope 200 is a steel rope.

The two clamping mechanisms 20 are configured to clamp the leash 200 in a staggered manner in sequence. The clamping mechanism 20, which is movably coupled to the frame 10, is configured to be movable in a forward direction in a first direction to feed the traction rope 200 when clamping the traction rope 200, and to be movable in a reverse direction in the first direction to clamp the traction rope 200 again when releasing the traction rope 200.

According to the conveying device 100 provided by the embodiment of the application, the two clamping mechanisms 20 can clamp the traction rope 200 in sequence in a staggered manner, namely when one clamping mechanism 20 loosens the traction rope 200, the other clamping mechanism 20 clamps the traction rope 200 in sequence in a staggered manner, and the conveying device 100 is ensured to clamp the traction rope 200 all the time.

In one embodiment, the first clamping mechanism is fixed and the second clamping mechanism is movably connected to the frame 10. The transport device 100 includes a drive mechanism 40, and the second clamping mechanism is coupled to the drive mechanism 40. Then, when the first clamping mechanism clamps the traction rope 200, the second clamping mechanism releases the traction rope 200, and at the same time, the driving mechanism 40 drives the second clamping mechanism to move in the first direction in the reverse direction and clamp the traction rope 200 again. When the second clamping mechanism clamps the traction rope 200, the driving mechanism 40 drives the second clamping mechanism to move forward along the first direction to deliver the traction rope 200, and at this time, the first clamping mechanism releases the traction rope 200. So as to reciprocate. The delivery device 100 achieves the purpose of delivering the pull-cord 200 while still gripping the pull-cord 200.

In another embodiment, the first clamping mechanism and the second clamping mechanism are both movably disposed on the frame 10 along the first direction, and the conveying mechanism includes two driving mechanisms 40, which are respectively defined as a first driving mechanism and a second driving mechanism. The first clamping mechanism is connected with the first driving mechanism, and the second clamping mechanism is connected with the second driving mechanism. Then, when the first clamping mechanism clamps the traction rope 200, the second clamping mechanism releases the traction rope 200, and at the same time, the first driving mechanism drives the first clamping mechanism to feed the traction rope 200 in the forward direction of the first direction, and the second driving mechanism drives the second clamping mechanism to move in the reverse direction of the first direction and clamp the traction rope 200 again. When the second clamping mechanism clamps the pulling rope 200, the second driving mechanism drives the second clamping mechanism to convey the pulling rope 200 forward along the first direction, and the first driving mechanism drives the first clamping mechanism to move reversely along the first direction and clamp the pulling rope 200 again. So as to reciprocate. The delivery device 100 achieves the purpose of delivering the pull-cord 200 while still gripping the pull-cord 200.

Further, each driving mechanism 40 includes two second driving members 41, and the two second driving members 41 are disposed on two opposite sides of the clamping mechanism 20 along the second direction, so as to ensure smooth movement of the clamping mechanism 20.

Further, two clamping blocks 21 are slidably connected with the frame 10 to be movable in the second direction with respect to the frame 10 to change the clamping width of the clamping space 22 in the second direction. Thus, by changing the interval between the two clamping blocks 21 in the second direction, the clamping width of the clamping space 22 can be adjusted to clamp or release the traction rope 200.
