摘要： A tube cutter comprises a main body, a cutting member and a base. The main body has a cutting space and a mounting portion corresponded to the cutting space. The cutting member, which is received in the main body, has a at least a portion protruding into the cutting space. The base has a first clamping portion and a second clamping portion; wherein the base is received in the mounting portion of the main body and can be switched between a first angle and a second angle. The first clamping portion is communicated with the cutting space to clamp a tube with a first predetermined diameter when the base is switched to the first angle. The second clamping portion is communicated with the cutting space to clamp a tube with a second predetermined diameter when the base is switched to the second angle.

摘要： A pipe bender includes: a body, a movable member, a return member, a stationary member, two adjustment members, two transverse positioning assemblies, two longitudinal positioning assemblies and a bending member. The movable member is disposed in the body, and an elastic member is disposed between the movable member and the body. A drive member and the return member are pivoted to the body, and the return member and the drive member are engaged with the rack of the body. The stationary member is fixed to the support portion of the body and arranged in a T-shaped manner with respect to the movable member. The two adjustment members are movably mounted at two ends of the stationary member to adjust a distance therebetween. A rotary block is fixed at the top of each of the adjustment members, and then the pipe bending member is mounted on the movable member.

摘要： A pipe expanding device includes: a clamping assembly including a pipe expanding end, an opposite connecting end, and a receiving space in communication with the pipe expanding end and the connecting end; a pipe expanding assembly movably disposed in the receiving space; a connecting member disposed at the connecting end; and an elastic member disposed in the receiving space and located between the pipe expanding assembly and the connecting member to push the pipe expanding assembly back toward the connecting end after the pipe expanding assembly is moved toward the pipe expanding end. The elastic member is hidden in the clamping assembly and capable of automatically pushing the pipe expanding assembly back to its original position. Therefore, the motion of the pipe expanding assembly won't be affected by the displacement of the pipe expanding tool, and the pipe expanding assembling therefore won't get bent or fall off.

摘要： A tube cutter comprises a main body, a cutting member, a first elastic member and a second elastic member. The main body has a cutting space and a rail. The cutting member is engaging the rail for movement and has at least a portion protruding into the cutting space; wherein the cutting member has a first preload portion and a second preload portion. The first elastic member, which is received in the main body and engaged with the first preload portion, provides a first elastic force on the first preload portion which is parallel to a first normal direction thereby. The second elastic member, received in the main body and rested against the second preload portion, provides a second elastic force on the second preload portion which is parallel to a second normal direction thereby.
