Novel semi-automatic chain opening and closing machine

The invention relates to the technical field of antiskid chain machining equipment, and particularly discloses a novel semi-automatic chain opening and closing machine which comprises a rack and a driving mechanism, the driving mechanism is arranged on the rack and comprises a motor and a driving rotating shaft connected with the motor, and the two ends of the driving rotating shaft are connected with a first driving mechanism and a second driving mechanism. The first driving mechanism and the second driving mechanism are connected with a chain opening mechanism and a chain pressing mechanism correspondingly, and the chain opening mechanism and the chain pressing mechanism conduct opening and pressing on chain rings on a chain correspondingly. According to the technical scheme, the motor is matched with the driving mechanism to enable the chain pressing mechanism and the chain opening mechanism to work on a chain ring, the noise of the equipment is low, the environmental protection requirement is met, the phy
