The invention discloses a scissor-type gate blocking apparatus with an adjustable blocking width of a gate leaf. According to its technical solutions, the apparatus comprises a shaft and an initiative swing arm . It also comprises an eccentric disk connected with the shaft and eccentrically provided with a plurality of mounted holes of the eccentric disk , an eccentric amount adjusting piece connected with the eccentric disk through the mounted hole of the eccentric disk , a small shaft eccentrically fixed at the eccentric amount adjusting piece , and a connecting rod mechanism adjusting its length retractably and connected with the initiative swing arm . The blocking apparatus has the advantages that it has a simple and practical structure and can adjust the blocking width of the gate leaf within a certain range. 1. A blocking apparatus of scissor-type gate with an adjustable blocking width of a gate leaf , comprises:{'b': '1', 'a main shaft ();'}{'b': '4', 'an initiative swing arm ();'}{'b': 21', '211', '1, 'an eccentric disk (), provided eccentrically with a plurality of mounted holes (), connected with the main shaft ();'}{'b': 22', '21', '211, 'an eccentric amount adjusting piece () connected with the eccentric disk () through the mounted holes ();'}{'b': 223', '22, 'a small shaft () fixed eccentrically at the eccentric amount adjusting piece (); and'}{'b': 3', '4, 'a connecting rod mechanism (), whose length is retractable, connected with the initiative swing arm ().'}2211.
