140N Electric Screwdriver
Traditional electric screwdrivers face fatal defects such as easy falling of accessories and damage to the machine by reaction force during high-altitude operations. The newly upgraded 140N tappable dual-speed electric screwdriver has an original chrome steel matrix tapping system and waist-hanging safety structure, equipped with 21-speed intelligent speed change + 2500mAh ternary lithium battery, which enables safe, efficient, and zero-damage operations in scenarios such as home appliance disassembly and assembly, aluminum alloy drilling, and high-altitude maintenance.
Core technical parameters
140N striking force: three-stage forged steel gear + buffer gap conduction technology, impact efficiency increased by 70%
Dual power mode:
✔ Low-speed gear: 0-400rpm (precise force control to disassemble and assemble precision screws)
✔ High-speed gear: 0-2000rpm (penetrate 6mm aluminum alloy/ceramic tile)
21-speed torque adjustment: from 0.2N.m electronic locking to 140N.m burst mode
10C power battery: 2500mAh capacity supports 90 minutes of continuous high-altitude operation
Analysis of 3 core innovations
1. Chrome steel matrix striking system (compared with competitor performance)
| Components | Solution | Conventional solution |
| Strike block material | 8mm thickened chrome vanadium steel (HRC58 hardness) | 2mm cast iron sheet (easy to break) |
| Force conduction design | Buffer gap + honeycomb matrix to disperse shock | Direct impact on the motor |
| Anti-resonance capability | 4 reinforcing ribs to eliminate 90% of vibration | Component resonance causes abnormal noise |
2. High-altitude operation safety system
Magnetic waist hanging module: 360° rotating buckle, tool shaking amplitude reduced by 80%
Anti-drop chuck: hexagonal handle screwdriver bit automatically locked after insertion (5N pulling force is required to pull out)
3. Fifth-generation brushless motor technology
Oxygen-free copper stator: continuous striking operation temperature rise ≤45℃ (industry average ≥70℃)
Intelligent power compensation: automatically maintains speed error ±3% when voltage fluctuates
4 Scenario solutions
High-altitude air conditioning maintenance
With a 30cm extended screwdriver, the screws of the external unit bracket can be removed with one hand
The waist-hanging design frees both hands, and the safety of climbing operations is improved by 60%
Customized installation for the whole house
21-speed torque adjustment: 1-speed hinge installation (anti-slip wire), 15-speed tapping wood screws
LED ring lighting: the illumination inside the dark cabinet reaches 300lux
Industrial equipment maintenance
140N burst mode: 1 second to remove the M12 rusted flange screws
Three-stage gearbox: withstand the axial impact force of up to 200kg
Emergency repair work
IP54 protection structure: outdoor use as usual on rainy days
Battery visualization: the remaining time is accurate to the minute
Suitable for all users
Time-saving: It only takes 3 seconds to remove the aluminum alloy window frame screws (15 seconds with traditional tools)
Labor saving: The cushioning knocking system reduces hand vibration by 70%
Cost saving: The life of chrome steel parts reaches 50,000 knocks (ordinary models ≤ 3,000 times)
Safety guarantee: The waist-hanging device reduces the risk of falling objects from high altitudes by 92%
The 140N electric screwdriver with strike function redefines the standard of aerial work tools with military-grade chrome steel protection and a 10C power battery. Whether you are a home appliance repairman or an engineering contractor, this professional tool with 21-speed intelligent speed change, waist-hanging safety system, and 140N burst torque will become your ultimate partner in tackling high altitudes, narrow gaps, and humid environments.
