摘要： A pneumatic rust-removing tool includes a main body having a chamber and an opening at a front end of the chamber, an impact block reciprocatingly moveable back and forth in the chamber, a spring disposed in the chamber, a mount disposed in the chamber and located between the impact block and the spring, rust-removing needles disposed with the mount and extending through the opening, and a slide sleeve disposed to the main body in a way that the slide sleeve is moveable back and forth relative to the main body. The slide sleeve is provided with a plurality of through holes, through which the rust-removing needles extend respectively. As a result, the pneumatic rust-removing tool can quickly adjust the exposed lengths of the rust-removing needles to adapt to different operational scenarios, thereby enhancing work efficiency and reducing the economic burden on the user.

摘要： A constant torque module for a power tool includes a transmission ring member, which has a core shaft, two accommodations and two drive blocks, two buffer units disposed respectively in parts of the accommodations such that each of the two accommodations remains a receiving space, an internal shaft member, which has two inner protrusions extending into the receiving spaces and being contactable with the two buffer units respectively, a shaft notch engaged with the core shaft, and a shaft rod having an engagement portion, and an external shaft member including two outer protrusions contactable with the two drive blocks respectively, and a shaft tube having an engagement notch engaged with the engagement portion of the internal shaft member. As such, the constant torque module outputs different torques when it rotates in reverse directions and has the advantages of high rotational speed, good working efficiency and low manufacturing cost.

摘要： An impact device includes a transmission shaft, an impact cylinder, two first impact pins and a first ring. The transmission shaft has an impacted section disposed in the impact cylinder, an extending section extending along an axis, a first protrusion extending toward a first radial direction, and two first concave surfaces located at the first protrusion. The impact cylinder has two elongated protrusions and two first radial holes separated by the elongated protrusions. The first impact pins are received in the first radial holes in parallel to the axis and abuttable against the first concave surfaces. The first ring is sleeved onto the impact cylinder and the first impact pins and has a first narrow groove in which one elongated protrusion is located, and a first wide groove in which the other elongated protrusion is movably located. The impact device has sufficient torque output and long lifetime.
