In tightening applications, the screwdriver must deliver stable torque and carries a certain weight. Prolonged operation can easily lead to operator fatigue and may also affect tightening quality due to human error. In such cases, the screwdriver assist arm becomes a key auxiliary device to address production pain points. As a brand deeply rooted in precision assembly, Danikor has introduced a screwdriver assist arm optimized and upgraded for industrial scenarios, further unlocking its technical value.

1. Balancing Weight + Counteracting Reaction Force to Reduce Operator Burden
When using a handheld screwdriver (especially high-torque models), the operator’s arm must continuously support the tool’s weight, which can easily cause strain on the shoulders, neck, and wrists during long hours of work. The assist arm uses a balancing structure to offset the weight of the screwdriver, allowing the operator to move the tool with minimal effort, significantly reducing physical strain.
During tightening, when the tool outputs high torque, a reaction force is generated. If this is fully borne by the operator, it may cause wrist injuries or even tool misalignment due to the reaction force. Danikor’s screwdriver assist arm can instantly counteract the torque reaction force, so the operator doesn’t need to resist it and can focus solely on aligning the tool with the screw. This ensures operational safety, reduces fatigue, and improves work efficiency.
2. Stabilizing Tool Posture to Eliminate Human Error
When holding a screwdriver manually, arm tremors or uneven force can easily cause the tool to tilt, resulting in “cross-threading”—where the screw and threaded hole are not concentric. This not only damages the threads but also reduces the pass rate. The assist arm’s rigid structure fixes the posture of the screwdriver, ensuring that the tool remains perfectly perpendicular and concentric with the screw during tightening, avoiding the risk of cross-threading.
3. Precise Positioning + Process Control to Improve Process Consistency
In assembly scenarios with multiple screws (such as automotive chassis or motor end covers), the tightening sequence and positional accuracy directly affect the balance of force on the workpiece. Danikor’s screwdriver assist arm can be equipped with high-precision encoders. By presetting the coordinates of tightening points, it ensures that each operation accurately targets the intended screw, preventing incorrect or missed tightening.
As industrial automation advances, the screwdriver assist arm has evolved from a “support tool” to a “quality assurance device.” Through technical optimizations in weight balance, posture stability, and precise positioning, Danikor’s assist arm not only reduces operator burden but also improves tightening quality and production efficiency from the source, becoming a critical support in precision assembly applications.
