The 21V brushless ratchet wrench can be used in confined space operations such as stage truss construction and automobile chassis repair. With its 3.5cm ultra-narrow head design and intelligent power system, it redefines the standard of professional-grade power tools. It becomes the secret weapon for the efficient operation of industry personnel.
Six core technological breakthroughs
1. Ultra-thin head space conqueror
► 3.5cm extremely narrow design, easily penetrates into mechanical gaps that traditional tools cannot reach ► No need to twist and insert, truss connection/engine compartment operation efficiency increased by 60% ► Quick-release chuck supports changing sleeves in seconds, equipped with 1/4″&3/8″ dual-specification adapters
2. Brushless power system
◆ Copper winding brushless motor, continuous output of 45N.m strong torque ◆ Intelligent temperature control technology ensures 800W high-power stable output ◆ Compared with carbon brush motor, the life is extended by 3 times, truly maintenance-free
● Push-type electronic speed regulation: heavy pressure directly reaches 210rpm high-speed mode, light pressure achieves 30rpm precision assembly ● 0.2-second emergency stop response, immediate braking when releasing the hand
Dual-mode intelligent switching
● One-button forward and reverse switching (supports mechanical/electronic dual locking) ● Built-in operation memory function, automatically maintains the last speed setting
Ultra-long battery life power pack
● Using 21700 power cells, the battery capacity is increased by 40% ● Intelligent BMS management system achieves: ● Triple temperature protection (-20℃~60℃ wide temperature range operation) ● Capacity retention rate > 80% after 2000 cycles ● 5-level power indicator + low voltage vibration reminder
Multi-scenario application test
Stage engineering case
In the assembly of 3.2-meter-high trusses, the bolt tightening work that takes 30 minutes with traditional wrenches only takes 8 minutes with this product, and there is no need to adjust the position repeatedly.
Automobile maintenance test
It only takes 9 seconds from start to finish to remove the front wheel bearing nut of the Toyota Corolla (standard torque 210N.m), which is 25% more efficient than pneumatic tools.
Warehouse shelf installation
When installing a shelf with a height of 1.5m, 32 M8 bolts are tightened in the narrow gap between the columns without changing tools.
