The adjusting member 3 is a cylindrical column structure, and the axis of the adjusting member 3 is parallel to the axis of the housing 1. By driving the assembly 4 to drive the mounting assembly to move parallel to the radial direction of the housing 1, the two adjusting members 3 symmetrically mounted on the mounting assembly along the axis of the housing 1 are driven to approach or move away from each other, so as to adjust the distance between the two adjusting members 3 in the radial direction of the housing 1 to adapt to the positioning holes of torque wrenches of different models.

The torque adjusting device of the torque wrench proposed in this application has the beneficial effect of being able to be compatible with the torque adjustment of torque wrenches produced by different models / different manufacturers.

[0031] It should be noted that the housing 1 can adopt a structure with a circular, triangular, rectangular, or polygonal cross-section.

[0032] In an exemplary embodiment of the present application, the driving assembly 4 includes a driving member 401 and a transmission member 402. The transmission member 402 is connected to the mounting member 2, and the driving member 401 is used to drive the transmission member 402 to drive the mounting member 2 to move parallel to the radial direction of the housing 1.

[0033] In this embodiment, the driving member 401 is a micro motor and is a two-way motor with a very slow rotation speed, which can finely adjust the distance between the two adjusting members 3 to adapt to the positioning hole positions of torque wrenches of different models. The transmission member 402 is a gear, and the mounting member 2 is provided with a strip tooth pattern 201, and the mounting member 2 meshes with the tooth pattern of the transmission member 402. By driving the transmission member 402 to rotate by the driving member 401, the two mounting members 2 are driven to approach or move away from each other to adjust the distance between the two adjusting members 3.

[0034] In an exemplary embodiment of the present application, two sliding grooves 101 are provided at one end of the housing 1 in the axial direction. The mounting member 2 is slidably connected to the sliding grooves 101, and the slotting length of the sliding grooves 101 is greater than the length of the mounting member 2.

[0035] In this embodiment, the length of the sliding groove 101 is greater than the length of the mounting member 2, so that the mounting member 2 has a certain range of movement and adjustment within the sliding groove 101, that is, the adjustable distance range between the two adjusting members 3.

[0036] In an exemplary embodiment of the present application, an avoidance groove 102 is provided on the housing 1, and the avoidance groove 102 communicates with the two sliding grooves 101.

[0037] In this embodiment, avoidance grooves 102 are formed in the side walls of two adjacent sliding grooves 101. The depth of the avoidance grooves 102 is the same as that of the sliding grooves 101. The transmission component 402 is installed at the position of the avoidance grooves 102. The avoidance grooves 102 are used to avoid the rotation of the transmission component 402 and prevent interference with the rotation of the transmission component 402.

[0038] In an exemplary embodiment of the present application, a first installation groove 103 and a through hole 104 are provided on the housing 1. The through hole 104 communicates the first installation groove 103 with the avoidance groove 102. The first installation groove 103 is used to install the driving component 401. The driving component 401 is connected to the transmission component 402 through the through hole 104. The transmission component 402 is located in the avoidance groove 102.

[0039] In this embodiment, the driving component 401 is installed in the first installation groove 103. The output shaft of the driving component 401 passes through the through hole 104 from the first installation groove 103 into the avoidance groove 102 and is connected to the transmission component 402. By providing the through hole 104, the output shaft of the driving component 401 can penetrate into the avoidance groove 102, so that the transmission component 402 can be fixed in the avoidance groove 102 and connected to the driving component 401.

[0040] In an exemplary embodiment of the present application, a second installation groove 105 is formed on the housing 1. The second installation groove 105 is used to install the mobile power supply 5. The mobile power supply 5 is electrically connected to the driving assembly 4. The mobile power supply 5 is used to provide power for the driving assembly 4.

[0041] In this embodiment, the mobile power supply 5 is a dry battery. A circuit for connecting the mobile power supply 5 to the driving component 401 is provided inside the housing 1. A forward switch and a reverse switch are provided on the housing 1 to make the driving component 401 rotate forward and reverse, so as to realize the mutual approach or separation of the adjusting components 3.

[0042] In an exemplary embodiment of the present application, the groove walls of the first installation groove 103, the second installation groove 105 and the avoidance groove 102 are all arc-shaped.

[0043] In this embodiment, since the outer wall surfaces of the micro motor and the dry battery are both arc-shaped surfaces, by designing the groove walls of the first installation groove 103 and the second installation groove 105 as arc-shaped surfaces, the driving component 401 and the mobile power source 5 are tightly attached to the wall surfaces of the first installation groove 103 and the second installation groove 105, reducing the designed diameter of the housing 1, which is beneficial to the lightweight effect of the adjusting device; since the transmission component 402 is a gear, the avoidance groove 102 is provided with an arc-shaped groove wall according to the diameter of the transmission component 402, reducing the cutting width of the wall surface of the sliding groove 101, and avoiding the occurrence of non-contact parts between the installation component 2 and the wall surface of the sliding groove 101, resulting in the installation component 2 falling into the avoidance groove 102, making the end of the installation component 2 abut against the wall surface of the avoidance groove 102, so that the installation component 2 cannot move, causing the problem that the distance between the adjusting components 3 cannot be adjusted.

[0044] In an exemplary embodiment of the present application, it further includes a first cover plate 106 and a second cover plate 107. The first cover plate 106 is used to close the first installation groove 103, and the second cover plate 107 is used to close the second installation groove 105.

[0045] In this embodiment, both the first cover plate 106 and the second cover plate 107 are arc-shaped cover plates. The first cover plate 106 and the second cover plate 107 are respectively engaged with the first installation groove 103 and the second installation groove 105 in a snap-fit manner, thereby sealing the first installation groove 103 and the second installation groove 105.

[0046] In an exemplary embodiment of the present application, it further includes a third cover plate 109. The third cover plate 109 is connected to the end of the housing 1. The third cover plate 109 is provided with a through groove 109a corresponding to the sliding groove 101. The through groove 109a is used for passing through the adjusting component 3, and the adjusting component 3 is slidably connected to the through groove 109a.

[0047] In this embodiment, the third cover plate 109 is a circular cover plate. The third cover plate 109 is connected to one end of the housing 1 where the adjusting assembly is provided. The third cover plate 109 is provided with two through grooves 109a corresponding to the sliding groove 101 in the thickness direction. The grooving track of the through groove 109a is the same as the grooving track of the sliding groove 101. The adjusting component 3 passes through the through groove 109a, and the adjusting component 3 is slidably connected to the through groove 109a. When the adjusting component 3 is inserted into the positioning hole of the torque wrench and the housing 1 is rotated, the through groove 109a can provide radial support for the adjusting component 3, so that the adjusting component 3 can bear a greater torque and reduce the risk of the adjusting component 3 being broken.

[0048] In an exemplary embodiment of the present application, the housing 1 is provided with an operating component 108, and the operating component 108 is used to drive the housing 1 to rotate.

[0049] In this embodiment, the operating component 108 is a cylindrical handle provided on the housing 1. The handle extends radially along the housing 1 and is located at one end of the housing 1 axially away from the adjusting assembly. When the torque adjusting device is in use, an operator turns on the switch on the housing 1, adjusts the distance between the adjusting components 3 according to the model of the torque wrench, inserts the adjusting components 3 into the positioning holes of the torque wrench, and the operator rotates the housing 1 through the handle to adjust the torque of the torque wrench. The handle can reduce the labor intensity of the operator when rotating the housing 1.

[0050] Working principle: The operator determines the position of the positioning hole according to the model of the torque wrench whose torque needs to be adjusted, turns on the switch on the housing 1 to adjust the distance between the adjusting components 3 to match the position of the positioning hole of the current torque wrench. When the switch is turned on, the driving component 401 is powered on with the mobile power source 5, and the driving component 401 drives the transmission component 402 to rotate. The transmission component 402 drives the mounting component 2 to move along the length direction of the sliding groove 101, thereby driving the adjusting components 3 to approach or move away from each other to adjust the distance between the adjusting components 3. After the distance between the adjusting components 3 matches the position of the positioning hole of the current torque wrench, the adjusting components 3 are inserted into the positioning holes of the torque wrench, and the operator holds the handle and rotates the housing 1 to adjust the torque of the torque wrench. By adopting the technical solution of the present application, the adjusting components 3 can be adjusted according to the positions of the positioning holes of torque wrenches produced by different models / different manufacturers, thus having the beneficial effect of being able to be compatible with the torque adjustment of torque wrenches produced by different models / different manufacturers.
