[0036] The utility model provides a torque meter and a torque wrench.

[0037] See also Figure 1 In one embodiment of the present utility model, the torque table includes:

[0038] The mounting housing 100 comprises a first side surface 110, a second side surface 120 and a third side surface 130 adjacent to the first side surface 110, the first side surface 110 comprises a groove 111, the second side surface 120 and the third side surface 130 are arranged opposite to each other, and both the second side surface 120 and the third side surface 130 are provided with an anti-slip structure 400;

[0039] The display panel 200 is disposed in the groove 111; and

[0040] The control key set 300 is disposed in the groove 111 so that the control key set 300 does not protrude from the first side surface 110 . The control key set 300 is communicatively connected with the display panel 200 .

[0041] In the technical solution of the utility model, the torque meter includes a mounting shell 100, a display panel 200 and a control key group 300, the display panel 200 and the control key group 300 are arranged on the first side 110 of the mounting shell 100, the torque value of the torque wrench is adjusted by the control key group 300, and the torque value is displayed through the display panel 200, and the control key group 300 and the display panel 200 are arranged on the same surface, so that the torque value can be adjusted while viewing; wherein a groove 111 is arranged on the first side 110 of the mounting shell 100, the bottom of the groove 111 is lower than the first side 110, the display panel 200 and the control key group 300 are both arranged in the groove 111, so that the control key group 300 and the display panel 200 are arranged on the same surface, and the torque value can be adjusted while viewing; The panel 200 does not protrude from the first side surface 110, that is, when taking the torque meter, the control key group 300 can be avoided from being accidentally touched, which affects the setting of the torque value and function, improves the convenience of operation, and can also avoid damage to the display panel 200. The control key group 300 does not protrude from the first side surface 110, so that the installation shell 100 is relatively flat, which improves the aesthetics of the torque meter. In addition, anti-slip structures 400 are respectively provided on the second side surface 120 and the third side surface 130 of the installation shell 100. When taking the torque meter, the fingers hold the second side surface 120 and the third side surface 130 respectively. The setting of the anti-slip part provides a better grip and operating experience, increases friction, reduces sliding, and improves the stability of the grip.

[0042] Among them, the installation shell 100 can adopt a square structure, one of the installation surfaces is set as the first side surface 110, the display panel 200 and the control key group 300 are installed on the first side surface 110, and the second side surface 120 and the third side surface 130 adjacent to the first side surface 110 are respectively provided with anti-slip structures 400. When the installation shell 100 needs to be taken, the fingers are on the second side surface 120 and the third side surface 130, so that the first side surface 110 is facing upward, or towards the direction of the user's eyes. On the one hand, the sliding friction is improved, and on the other hand, it is convenient to view the torque value in real time through the display panel 200 when the control key group 300 adjusts the torque value.

[0043] In the embodiment of the present invention, the anti-skid structure 400 is configured as an anti-skid groove, and the second side surface 120 and the third side surface 130 are both recessed toward the inside of the mounting housing 100 to form the anti-skid groove.

[0044] Specifically, see Figure 1 and Figure 2, the anti-skid structure 400 is configured as an inwardly recessed anti-skid groove. Specifically, the middle part of the second side surface 120 is recessed toward the inside of the mounting shell 100 to form an anti-skid groove, and the recess extends from the first side surface 110 toward the surface opposite to the first side surface 110, so that on the second side surface 120, both sides of the anti-skid groove are higher than the anti-skid groove. It can be understood that on the third side surface 130, the anti-skid groove is set the same as the second side surface 120. When the torque meter needs to be grasped, according to usage habits, the thumb and the remaining fingers grasp the second side surface 120 and the third side surface 130 respectively. Taking the thumb grasping the second side surface 120 as an example, since the anti-skid groove is set on the second side surface 120, the thumb can contact the position between the anti-skid groove and the second side surface 120, which is convenient for borrowing force to pick up, improves the stability of the grip, facilitates better grip, and increases the sliding friction. The same is true for the third side surface 130.

[0045] In the embodiment of the present utility model, the control key group 300 includes an adjustment button 310 for adjusting the torque value. A first slot is provided at the bottom of the groove 111. The adjustment button 310 is provided at the first slot so as not to protrude from the bottom of the groove 111.

The torque value set by the torque wrench is adjusted by the up-adjustment button and the down-adjustment button, and the torque value is displayed through the display panel 200. The adjustment button 310 can be a button. By pressing the up-adjustment button or the down-adjustment button to adjust the value, for example, by pressing the up-adjustment button, the torque value is increased, and by pressing the down-adjustment button, the torque value is decreased. When the up-adjustment button or the down-adjustment button is pressed at the same time, the display panel 200 flips the interface. It can also be set as a knob. The setting knob is rotated clockwise to increase the torque value, and the knob is rotated counterclockwise to reduce the torque value. It can be understood that the rotation direction of the knob is not limited to the present embodiment. In addition, a first slot is provided at the bottom of the groove 111. The adjustment button 310 is provided on the first slot, and the top of the adjustment button 310 does not protrude from the bottom of the groove 111, which not only improves the flatness of the surface of the mounting shell 100, but also further avoids accidental touching of the adjustment button 310.

[0048] In the embodiment of the present invention, the control key set 300 further includes a function key 320 . A second slot is disposed at the bottom of the recess 111 . The function key 320 is disposed at the second slot so as not to protrude from the bottom of the recess 111 .
