Abstract
A torque wrench has a hollow tubular body. A long rod and a short rod are provided in the hollow tubular body. The hollow tubular body is formed with a first through hole and a second through hole respectively corresponding to the long rod and the short rod. A first limiting unit is provided in the first through hole, and a second limiting unit is provided in the second through hole. The first limiting unit enables to slide into a first gap spaced apart between the long rod and the hollow tubular body to limit the swing range of the long rod, and the second limiting unit enables to slide into a second gap spaced apart between the short rod and the hollow tubular body to limit the swing range of the short rod, thereby improving the accuracy of the tripping torque and making the torque wrench easy to calibrate.
Claims10
A torque wrench, comprising a hollow tubular body, one end of the hollow tubular body being connected to a drive head, the other end of the hollow tubular body being connected to a grip, a trip mechanism being provided in the hollow tubular body, the trip mechanism having a long rod and a short rod arranged side by side, a trip member being connected between the long rod and the short rod, the trip member being configured to trip when the trip mechanism reaches a predetermined torque value, the trip mechanism being further connected with an adjustment unit configured to adjust the predetermined torque value;
- a first gap being spaced apart between an inner wall surface of the hollow tubular body and one side of the long rod, a second gap being spaced apart between the inner wall surface of the hollow tubular body and one side of the short rod, an outer wall surface of the hollow tubular body being formed with a first through hole communicating with the first gap and a second through hole communicating with the second gap;
- a first limiting unit, accommodated in the first through hole and having a first sliding member, the first sliding member being slidable in the first through hole, one side of the first sliding member having a first limiting portion extending toward the first gap, another side of the first sliding member being provided with a first pushed portion, the first pushed portion being connected with a first pushing member, the first pushing member being configured to apply a force to the first pushed portion toward the first gap to make the first sliding member having a movement tendency toward the first gap and to make the first limiting portion restricted in the first gap;
- a second limiting unit, accommodated in the second through hole and having a second sliding member, the second sliding member being slidable in the second through hole, one side of the second sliding member having a second limiting portion extending toward the second gap, another side of the second sliding member being provided with a second pushed portion, the second pushed portion being connected with a second pushing member, the second pushing member being configured to apply a force to the second pushed portion toward the second gap to make the second sliding member having a movement tendency toward the second gap and make the second limiting portion restricted in the second gap.
