1. A multi-processing device for an endoscope, comprising:
a plurality of processing units, the plurality of processing units including a most distal processing unit and at least one non-distal processing unit, each processing unit including a capsule body and clamping arms, the clamping arms being accommodated in the capsule body and moving to form an open configuration and a closed configuration, a proximal end of the capsule body being provided with a first limit part that is available for deformation or failure under an external force;
a conveying component including a conveying pipe for accommodating the plurality of processing units and a control member passing through the conveying pipe, a distal end of the conveying pipe being provided with a baffle extending towards an axial center of the conveying pipe, the control member being configured to drive a most distal processing unit in the plurality of processing units to switch from a combination configuration to a release configuration, wherein in the combination configuration, the most distal processing unit among the processing units is connected with the distal end of the conveying pipe, and in the release configuration, the most distal processing unit is separated from the distal end of the conveying pipe; and
an operation component including a handle part connected with a proximal end of the conveying pipe and a sliding part sleeved on the handle part, the sliding part being connected with a proximal end of the control member, and the sliding part configured to drive movement of the control member;
the operation component being configured to drive the at least one non-distal processing unit to move along a direction from the proximal end of the conveying pipe to the distal end of the conveying pipe, so that the most distal processing unit in the at least one non-distal processing unit arrives at the distal end of the conveying pipe;
wherein at least one of the distal end of the conveying pipe or the proximal end of the capsule body is provided with a second limit part, the second limit part is configured to abut against the baffle, and expand and contract along a radial direction of the conveying pipe.
