Features are set on the trigger. The trigger sensor detects the trigger pull signal and transmits it to the host to control feeding, air supply and motor start. There is a trigger return spring between the trigger and the housing, and the lower claw of the trigger moves upward. An upper claw mechanism is arranged above the lower claw. 2. The hand-held automatic cable tie tool according to claim 1, characterized in that: it also includes a counting gear sensor, the counting gear sensor is arranged in the axial direction of the counting gear and is arranged next to the counting gear, and features are set on the counting gear, The counting gear sensor can detect this feature and send a signal to control the motor to stop moving and complete a cable tie working cycle. 3. The hand-held automatic cable tie tool according to claim 1, characterized in that: the binding tightness adjustment mechanism includes an adjustment screw, a vernier, an adjustment spring, and a slider, and the slider, the adjustment spring, and the vernier are coaxial Installed on the adjusting screw, one end of the adjusting screw is sleeved on the frame and the adjusting screw can only rotate around its own axis, the other degrees of freedom of the adjusting screw are limited by the frame, the vernier It is threadedly connected with the adjusting screw, and the vernier has a structure to prevent rotation. When the adjusting screw is rotated, the vernier moves along the axis of the adjusting screw and compresses or releases the adjusting spring. There is a fork-shaped structure, the slider is arranged adjacent to the fork-shaped structure above the planetary wheel base, the elastic force of the adjustment spring acts on the slider, and the slider then acts the elastic force on the planetary wheel base On the upper fork structure and make the fork structure above the planetary wheel base close to the frame, the strapping tightness adjustment mechanism locks the planetary wheel base by elastic force, and rotates the adjustment screw of the strapping tightness adjustment mechanism That is to adjust the size of the elastic force, that is, to set the threshold for cutting by the cutter, that is, to adjust the tightness of the bundle. 4. The hand-held automatic cable tie tool according to claim 1, wherein the upper claw mechanism includes an upper claw, a swing lever, and a cam follower, and one end of the upper claw is connected to the swing lever, The other end of the swing rod is connected with the cam follower, and the cam follower is controlled by the cam, and an upper and lower claw connector is provided between the lower claw and the upper claw, and the upper claw and the lower claw and Both the upper and lower claw connectors have grooves to guide the cable tie. After the trigger is pulled, the lower claw swings upward through the trigger link, and the upper claw, the lower claw and the upper and lower claw connectors form a closed circle; the cable tie is compressed The air is pushed into the closed circle formed by the upper claw, the lower claw and the connecting parts of the upper and lower claws for positioning. The upper claw swings inward under the drive of the motor, so that the tail of the cable tie penetrates into the hole in the head of the cable tie. The movement of the lower claw is controlled by the trigger. , The trigger link is manually controlled, and the trigger reset spring resets; when the spring is at the reset position, the upper jaw and the lower jaw are in an open state. 5. The hand-held automatic cable tie tool according to claim 1, characterized in that: the feeding tube is a flexible square-section feeding tube. 6. The hand-held automatic cable tie tool according to claim 1, characterized in that: the periphery of the active winding wheel and the passive winding wheel is designed as a tooth shape, and the active winding wheel and the passive winding wheel are respectively After being assembled with the driving winding gear and the passive winding gear, the driving winding wheel shaft and the passive winding wheel shaft, regardless of the rotation to any angle orientation, the peripheral teeth of the driving winding wheel and the passive winding wheel The shape is always convex and concave relative to each other. 7. The hand-held automatic cable tie tool according to claim 1 or 3, characterized in that: the binding tightness adjustment mechanism adopts an adjustment screw, a slider, an adjustment spring, and a vernier, and the elastic force of the binding tightness adjustment mechanism Lock the base of the planetary wheel, set the resistance for the cutting action of the cutter, and ensure that the winding action takes precedence over the cutting action; when the cutter cuts the tie, the binding tightness adjustment mechanism pushes the planetary wheel base to rotate around the axis of the sun gear Reset the cutter.
