Abstract
An impact powered torque wrench has a force-applying rod. The force-applying rod is connected to a transmission rod. A transmission shaft is disposed in the transmission rod. Two ends of the transmission shaft are connected to a head unit and a drive unit, respectively. A trip unit and an adjustment unit are provided between the force-applying rod and the transmission rod. An impact unit is provided between the transmission shaft and the drive unit. The drive unit drives the transmission shaft by means of intermittent impact, which increases the output torque and has a higher level of operational safety.
Claims3
An impact powered torque wrench, comprising:
- a force-applying rod;
- a transmission rod, disposed along an axial direction of the force-applying rod, the transmission rod being swingable left and right relative to the force-applying rod;
- a transmission shaft, rotatably disposed in the transmission rod;
- an impact unit, connected to one end of the transmission shaft;
- a drive unit, connected to the impact unit;
- a head unit, connected to another end of the transmission shaft;
- a trip unit, disposed between the force-applying rod and the transmission rod, wherein when the transmission rod is pulled by a user, an acting force is transmitted to the force-applying rod via the tripping unit;
- when the acting force reaches a torsion value, the trip unit trips;
- wherein the impact unit includes a driving member connected to the drive unit, an impact member driven by the driving member, and an output shaft connected to the transmission shaft, the impact member and the output shaft are not connected to each other, when the drive unit drives the driving member to rotate, the driving member drives the impact member to impact the output shaft intermittently, enabling the output shaft to rotate and drive the head unit to actuate.
