Abstract

The invention discloses a bridge type wrench. The bridge type wrench comprises a wrench head, an inner sleeve rod, an outer sleeve and a force measurement head, wherein the end part of the wrench head is clamped in an end face clamping groove of a first end of the inner sleeve rod; a second end of the inner sleeve rod is clamped in an end face clamping groove of a first end of the outer sleeve; the end part of the force measurement head is clamped in an end face clamping of a second end of the outer sleeve; sleeve rod locking parts which penetrate through the pipe wall of the outer sleeve are arranged; when the sleeve rod locking parts are positioned in first positions, the inner sleeve rod is fixed relative to the outer sleeve; and when the sleeve rod locking parts are positioned in second positions, the inner sleeve rod can slide relative to the outer sleeve. According to the bridge type wrench, the technical problem that the utilization of a conventional torque wrench is limited by space is solved, and the bridge type wrench can operate at parts which have narrow spaces and do not have operation spaces.

Description

technical field [0001] The invention relates to the field of mechanical tools, in particular to a bridge type wrench. Background technique [0002] Torque wrench is also called torque wrench. Torque is the product of force and distance. When tightening screws, bolts, nuts and other threaded fasteners, it is necessary to control the applied torque to ensure that the thread is tightened and the thread will not be damaged due to excessive torque. Use a torque wrench to operate. First, set a required upper limit of the torque value. When the applied torque reaches the set value, the wrench will make a "click" sound or the wrench connection will bend a little, which means that it has been tightened and no further force is required. [0003] Existing torque wrenches can be divided into: preset torque wrench, digital display torque wrench, MINI type torque wrench, fixed value torque wrench, dial torque wrench. However, these torque wrenches cannot measure torque in grooves, gaps ...
