Document Type and Number:
Japanese Patent JP2023069279
Kind Code:
A
Abstract:
To provide an improved rotation mechanism of a jaw in a pipe expanding tool for expanding an end of a pipe.SOLUTION: The expanding tool has a wedge, a plurality of jaws, a spring, and a first rotary member. The wedge can be reciprocated along a first axis between a first position and a second position. The plurality of jaws are movable about the first axis to a closed position and an open position radially outward from the closed position, and are rotatable about the first axis. The plurality of jaws are configured to move from the closed position to the open position in response to movement of the wedge from the first position to the second position and to move from the open position to the closed position in response to movement of the wedge from the second position to the first position. The first rotary member is integrally rotatable with the plurality of jaws and engages the plurality of jaws. The first rotary member is configured to rotate in only one direction around the first axis by the elastic force of the spring.SELECTED DRAWING: Figure 2
