1. A stuck staple processing mechanism of an electric stapler, comprising:
a driving mechanism;
a transmission mechanism;
a pop-up staple channel assembly;
a controller; and
a pop-up mechanism, wherein the transmission mechanism is connected with a pop-up switch of the pop-up staple channel assembly through the pop-up mechanism; when the controller controls the driving mechanism to rotate in a staple placing direction, the pop-up mechanism does not make the staple channel assembly act; when the controller controls the driving mechanism to rotate in an opposite direction of staple placing, the transmission mechanism makes the pop-up switch act through the pop-up mechanism to pop up a staple channel of the staple channel assembly, so as to facilitate a removal of a stuck staple;
wherein the pop-up mechanism comprises a side wheel, a lever and a pressing pin, the pop-up switch comprises a key lock assembly, the side wheel is fixed on the transmission mechanism and rotates with the transmission mechanism, a middle part of the lever is rotatably fixed on a machine base, one end of the lever is driven by the side wheel, an other end of the lever is unidirectionally transmitted with the pressing pin, the pressing pin is guided by the machine base and arranged on the key lock assembly of the staple channel assembly, when the side wheel rotates in the staple placing direction, the one end of the lever is driven to be downward and the other end is driven to be upward away from the pressing pin; when the side wheel rotates in the opposite direction of staple placing, the one end of the lever is driven to be upward and the other end is driven to press the pressing pin, and the pressing pin is downward to unlock the key lock assembly of the staple channel assembly and pop up the staple channel of the staple channel assembly.
