The shape and size of the strip groove match the torque adjustment controller, and the torque adjustment controller is clamped in the strip groove, so that the torque adjustment controller can be completely installed by pushing it in from one side, which has the advantages of simple structure and easy assembly.

[0015] In the torque wrench case assembly, a strip-shaped crushing groove is provided in the middle of the rear end surface of the rear cover and is arranged along the length direction of the torque adjustment controller. There are two strip-shaped crushing grooves, and the torque adjustment controller is located between the two strip-shaped crushing grooves. The provision of the strip-shaped crushing grooves can make the strip-shaped grooves more susceptible to compression deformation, which is beneficial to the installation of the torque adjustment controller and enhances the installation stability of the torque adjustment controller.

[0016] In the above-mentioned torque wrench housing assembly, the cross section of the strip-shaped crushing groove is trapezoidal.

[0025] like Figure 1 As shown, the torque wrench housing assembly includes a housing body 1 and a torque adjustment controller 2 disposed outside the housing body 1. The specific structure of the torque adjustment controller 2 and the communication method between the torque adjustment controller 2 and the torque wrench are both existing. For details, reference may be made to an electric wrench with adjustable torque disclosed in the Chinese Patent Library (application number: 201020268793.2), which will not be described in detail here.

[0026] Specifically,

[0027] The housing body 1 includes a handle 1a, a barrel 1b horizontally arranged above the handle 1a, and a rear cover 1c fixed to the rear end of the barrel 1b. The torque adjustment controller 2 is fixed on the rear cover 1c, and the rear cover 1c is provided with a through hole for the cable of the controller to extend into the barrel 1b, and the through hole is arranged opposite to the torque controller.

[0028] like Figure 1 As shown, the torque adjustment controller 2 is in the shape of a long strip, and the length extension direction of the torque adjustment controller 2 is perpendicular to the axial direction of the barrel 1b. The torque adjustment controller 2 is arranged in the middle of the rear end surface of the rear cover 1c, and the upper and lower sides of the rear end surface of the rear cover 1c are provided with heat dissipation ports 1c1 that connect the inner cavity of the rear cover 1c to the outside.

[0029] Heat dissipation ports 1c1 are provided on both the upper and lower sides of the torque regulating controller 2, i.e., the heat dissipation ports 1c1 are not blocked by the torque regulating controller 2, so that the heat concentrated at the rear cover 1c can be discharged faster through the heat dissipation ports 1c1, thereby effectively reducing the working temperature of the torque regulating controller 2, thereby extending the life and working stability of the torque regulating controller 2.

[0030] Further explanation, the heat dissipation opening 1c1 is in strip shape, and the length extension direction of the heat dissipation opening 1c1 and the torque adjustment controller 2 are parallel. At least two heat dissipation openings 1c1 are provided on both upper and lower sides of the rear end surface of the rear cover 1c, and the multiple heat dissipation openings 1c1 on the same side are distributed along the length extension direction of the torque adjustment controller 2. Preferably, two heat dissipation openings 1c1 are provided on both upper and lower sides of the rear cover 1c. The heat dissipation of the rear cover 1c can be further accelerated by setting the heat dissipation openings 1c1 in strip shape and providing a row of heat dissipation openings 1c1 on both upper and lower sides of the rear cover 1c.

[0031] like Figure 1 and Figure 3 As shown, the inner side of the rear end surface of the rear cover 1c has a horizontally arranged strip cover 1d, and the length of the strip cover 1d extends along the length direction of the torque adjustment controller 2.

A tortuous channel is formed between the heat dissipation port 1c1 and the strip cover 1d to connect the inner cavity of the barrel 1b with the outside. On the premise of ensuring the heat dissipation performance, large particles of impurities can be prevented from entering the barrel 1b through the heat dissipation port 1c1, ensuring the stable operation of the torque wrench.

[0032] In this embodiment,

[0033] The strip-shaped cover 1d and the rear cover 1c are an integrated structure to ensure the stability and strength of the connection between the two. Preferably, the strip-shaped cover 1d and the rear cover 1c are made of plastic material and are integrally formed by injection molding.

[0034] like Figure 1 and Figure 2 As shown, the installation method of the torque adjustment controller 2 is as follows: a strip groove 1e is provided in the middle of the rear end face of the rear cover 1c and is arranged along the length direction of the torque adjustment controller 2. The shape and size of the strip groove 1e match the torque adjustment controller 2, and the torque adjustment controller 2 is clamped in the strip groove 1e, so that the torque adjustment controller 2 can be completely installed by pushing it in from one side, which has the advantages of simple structure and convenient assembly. Further explanation: a strip crushing groove 1f is also provided in the middle of the rear end face of the rear cover 1c and is arranged along the length direction of the torque adjustment controller 2. There are two strip crushing grooves 1f, and the torque adjustment controller 2 is located between the two strip crushing grooves 1f. The provision of the strip crushing groove 1f can make the strip groove 1e more susceptible to compression deformation, which is beneficial to the installation of the torque adjustment controller 2 and enhances the installation stability of the torque adjustment controller 2. Preferably, the cross-section of the strip crushing groove 1f is trapezoidal.

[0035] In the actual product, the torque adjustment controller 2 includes a display screen 2a and a torque adjustment button 2b.
