The connector crimping device according to claim 11, characterized in that: A gear portion (51) is formed on the scale plate (5), and a plurality of tooth grooves (51a) on the gear portion (51) respectively correspond to a plurality of scale marks (50) on the scale plate (5); A locking tooth (61) is formed on the locking member (6), and the locking member (6) is rotatably connected to the rotating member (4) and is rotatable between a locking position and an unlocking position; When the locking member (6) is rotated to the locking position, the locking teeth (61) mesh with the corresponding tooth grooves (51a) on the gear portion (51) to lock the mounting shaft (3) and the rotating member (4) at the predetermined angular position; When the locking member (6) is rotated to the unlocking position, the locking tooth (61) is disengaged from the tooth groove (51a) on the gear portion (51) to allow the mounting shaft (3) and the rotating member (4) to rotate relative to the dial (5).

13. The connector crimping device according to claim 7, characterized in that: Also includes: A sensor (7) is fixedly mounted on the first moving block (1) and is used to detect a moving distance of the second moving block (2) relative to the first moving block (1) in the first direction (Z).

14. The connector crimping device according to claim 13, characterized in that: A reference block (8) is mounted on the second moving block (2), and the reference block (8) has a reference surface (8a) perpendicular to the first direction (Z); The sensor (7) is fixedly mounted on the block body (10) of the first moving block (1) and faces the reference surface (8a) of the reference block (8) to detect the distance between the sensor (7) and the reference surface (8a); The moving distance of the second moving block (2) relative to the first moving block (1) in the first direction (Z) is equal to the moving distance of the reference surface (8a) relative to the sensor (7).

15. The connector crimping device according to claim 13, characterized in that: The sensor (7) is a laser distance sensor, an ultrasonic distance sensor or an infrared distance sensor.

16. The connector crimping device according to claim 1, characterized in that: Also includes: A driving device is connected to the first moving block (1) and is used to drive the first moving block (1) and the second moving block (2) to move together along the first direction (Z).
