[0032] As shown in Figure 3 And Figure 4 The middle part of the lock body 1 is provided with the executing assembly 4, the executing assembly 4 includes the extension rotating rod 42, the friction force detection piece, the short protruding block 46, the long protruding block 47 and the lock cylinder 48, the friction force detection piece is arranged at the arc surface of the extension rotating rod 42, the friction force detection piece includes the resistance box 43, the resistance block 44 and the spring sheet 45, the resistance box 43 is fixedly installed at the arc surface of the extension rotating rod 42, the resistance block 44 is slidably connected in the resistance box 43, the resistance block 44 is fixedly installed in the resistance box 43, and the other end of the resistance block 44 is in contact with the resistance block 44.

[0033] The lock cylinder 48 is fixedly installed in the inside of the positioning groove 3, the two short protruding blocks 46 symmetrically arranged are fixedly installed on the inner arc surface of the lock cylinder 48, and the friction force detection piece is located between the two short protruding blocks 46. The top of the resistance block 44 is in contact with the short protruding block 46, the top of the short protruding block 46 adopts an arc structure, the end of the extension rotating rod 42 is fixedly installed with the electric rotating rod 41, and the electric rotating rod 41 is fixedly installed on the side of the lock shell 2.
