Its end passes through the opening 125 and the rotation port 123 and is installed with the backstop bearing 31 and the planetary reducer 33. The drive motor 34 is mounted on the right housing 13 and is installed with the planetary reducer 33. The drive motor 34 drives the planetary reducer 33 to rotate the rotating shaft 32.

[0019] The speed control switch 4 is located in the outer casing 1 and is connected to the controller 11. The controller 11 is connected to the drive motor 34. The speed control switch 4 controls the rotation speed of the drive motor 34. After the cable tie is tied, its tail first passes through the front part of the cable tie channel 212, then passes through the cutting edge 211 and the rear part of the cable tie channel 212 in sequence, and finally enters the rotating shaft 32. The rotating shaft 32 pulls the cable tie through the cutting blade holder 21. After the cable tie is tightened, the cutting blade holder 21 rotates to drive the cutting blade 22 to cut the tail of the cable tie at the cutting edge 211. That is, the cutting blade 22 is rotated so that its blade head rotates from a horizontal state to cut the cable tie and break it.

[0020] A notch is provided between the left shell 12 and the right shell 13. The two notches are joined together to form a switch port. The speed control switch 4 is movably installed in the switch port through an elastic reset member.

[0025] In this embodiment, the drive motor is connected to and driven by a planetary reducer. The planetary reducer and the shaft have the same diameter, which can increase the tension of the cable tie while avoiding excessive load on the drive motor. At the same time, an anti-backlash bearing is added to prevent excessive binding force and prevent the motor from reversing after a power outage. The binding is more secure, reducing the equipment failure rate and extending the service life of the cable tie machine.

[0026] The controller 11 is equipped with an overcurrent protection module, which monitors the current of the drive motor and feeds it back to the controller to control the switching of the drive motor. By monitoring the current of the tightening protection, the power can be automatically cut off after tightening. This eliminates the need for manual observation of whether tightening has occurred and protects the drive motor from overcurrent damage, thus extending its service life.

[0027] This embodiment uses current regulation to simplify the tool structure, resulting in a smaller, lighter, and longer-lasting tool. The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
