The invention discloses a blade lock. On the working condition that a lock is closed, a lock closing groove (9) with an opening in the direction of a spring bolt is formed in the place where a blade clamping tenon (7) makes contact with limiting resistance iron (12); the width of L1 must ensure that the limiting resistance iron (12) can be stopped and a lock can be completely locked when the lock is closed; the width of L2 must ensure that the limiting resistance iron (12) is pulled into the lock closing groove (9) with no barrier; the depth of L3 must ensure that the lock closing clamping tenon (7) can be firmly locked after the limiting resistance iron (12) enters the lock closing groove (9), and meanwhile a clamping angle (8) inside the lock closing groove can stop the limiting resistance iron (12); the length of L4 must ensure that the limiting resistance iron (12) does not make contact with a lower vertex angle (9) of the lock closing groove; the width of L5 will not move the limiting resistance iron from the lower face of the lower vertex angle (11) in the lock opening direction due to the fact that the width of L5 is small. On the working condition that the lock is closed, a slope with the sharp front part and the large rear part is sheared on the side, making contact with the lock closing clamping tenon (7), of the limiting resistance iron (12), the bevel edge of the slope is a guiding slope (14), the limiting resistance iron (12) is pushed into the lock closing groove (9) by means of the unique function of the guiding slope (14), and the phenomenon that a master key can open the lock is successfully avoided.
