Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a screwdriver bit for installing and removing clamp screws. Background Art

[0002] The clamp is a connecting device for connecting grooved pipes, valves and pipeline accessories. It is used to tighten quick connectors. It has good performance, high sealing and easy installation.

[0003] "Clamps" are used in the detachable connection structure of a large number of pipes in current fluid circulation equipment, especially in the clamps of fire protection pipes, which have certain special structures, such as Figure 1 As shown, it includes an upper ring and a lower ring, one end of the upper ring and the lower ring are hinged, the other end of the upper ring is riveted with a clamp screw, and the clamp screw is threaded with a bolt. When the bolt is tightened, it will move on the clamp screw, and the bolt will press against the other end of the lower ring, thereby tightening the other end of the upper ring and the lower ring, thereby completing the installation of the clamp. At the same time, disassembly only requires rotating the bolt in the opposite direction;

[0004] However, due to the special structure of this bolt, there is currently no screwdriver bit that can match this bolt on the market. It can only be tightened, installed and disassembled by relying on an adjustable wrench or manual labor, which is labor-intensive for operators and has low work efficiency. In addition, manual operation cannot accurately control the torque of the bolt tightening. When the torque is too small, the pipeline connection cannot be sealed.
