3、 Structural analysis
Head system:
Double sided ratchet head+ratchet torque square head: compatible with dual specifications, covering multiple types of bolts (such as hexagonal and square heads), flexible switching, and improved job compatibility.
Central functional area:
Directional paddles: One click switching between forward and reverse, quickly adapting to fastening/disassembly needs, with high operational efficiency.
Large LCD screen: high-definition real-time display of torque values, units, and working modes, clear and visible in low light environments, bidding farewell to "blind twisting".
Communication port: Supports torque data export (such as connecting to computers/mobile devices), facilitating quality traceability and process analysis, and adapting to digital production lines.
Buzzer: When the set torque is reached, it will sound and light dual alarms (beep+screen display prompt), forcing standardized operation and avoiding human error.
Operation buttons (C/U/V, etc.): Implement functions such as mode switching, unit conversion, data storage/clearing, etc., with simple and efficient interaction.
Tail and handle:
Battery cover: quick release design, easy to replace battery, ensuring continuous operation; The built-in battery has stable battery life (specific parameters can be found in the manual).
Anti slip handle: Ergonomic curved surface+anti slip texture, comfortable grip, reduces long-term operation fatigue, and improves grip stability.
4、 Core functional highlights
High precision torque control:
The accuracy reaches ± 1% (within the full range), ensuring that each tightening strictly meets the standards and avoiding the risk of "over tightening, fracture, under tightening, and loosening".
Multi mode adaptation:
Tracking mode: dynamically display applied torque, adapt to debugging scenarios, and monitor the entire tightening process.
Peak mode: Record the maximum torque during the tightening process for easy review of key nodes afterwards.
Preset mode: Set the target torque, automatically sound an alarm when it meets the standard, and enforce standardized operating procedures.
Flexible switching of units:
Supports switching between N · m, ft · lb, kgf · cm units, covering metric/imperial standards, and adapting to torque specifications in multiple industries such as automotive, electronics, and home furnishings.
Data management:
Built in storage module, capable of recording multiple sets of torque data; Combining communication functions to achieve data export and information management, assisting in quality traceability and process optimization.
Durability and reliability:
The main body is made of chromium vanadium alloy steel, which is impact resistant, corrosion-resistant, and stable and reliable in dealing with complex working conditions such as oil pollution/vibration; The internal sensors have undergone rigorous calibration, resulting in low precision degradation over long-term use.
5、 Typical application scenarios
Automotive interior assembly: precise torque control for seat screws, central control module, headlight fixation, etc., to avoid damaging plastic parts.
Electronic equipment maintenance: tighten screws on mobile phones, laptops, and industrial controllers to ensure the lifespan of components.
Small mechanical installation: Assembling core components of drones, robots, and power tools to enhance product stability.
Home and DIY: Installation of cabinet hinges, bathroom hardware, and fitness equipment, balancing precision and ease of operation.
