[0002] Torque wrench, also known as torque wrench, torque wrench, torque adjustable wrench, is a type of wrench. Currently, the common ones on the market are manual torque wrenches, electric torque wrenches, and pneumatic torque wrenches. Among them, some wrenches are equipped with digital display devices, which detect and display the torque when the wrench is in use.

[0003] At present, digital torque wrenches are generally divided into two types according to their length: long handle and short handle. Long handle digital torque wrenches are easier to use, but are easily limited by the use space. Short handle digital torque wrenches can be used in some small spaces, but are more laborious to use. Moreover, when the digital torque wrench is not in use, the display screen is difficult to be effectively protected and is easily damaged by external forces. Therefore, the utility model proposes a foldable digital torque wrench. Utility Model Content

[0027] Example:

[0028] See also Figure 1-4A foldable digital torque wrench comprises a wrench body 1, the bottom end of the wrench body 1 is fixedly connected to a connecting column 2, the outer surface of the connecting column 2 is rotatably connected to a foldable protective handle 3, the outer surface of the foldable protective handle 3 is rotatably connected to a rotating handle 4, a limiting mechanism is arranged between the foldable protective handle 3 and the connecting column 2, the limiting mechanism is used to limit the rotation of the foldable protective handle 3, so that the connection between the foldable protective handle 3 and the connecting column 2 remains fixed.

[0029] In this embodiment, the foldable protective handle 3 is folded on the wrench body 1, and cooperates with the rotating handle 4 to wrap the wrench body 1, so as to protect the digital display device on the wrench body 1. When the digital torque wrench is in use, the rotating handle 4 is rotated to the outer surface of the foldable protective handle 3, and then the limiting mechanism is opened, so that the foldable protective handle 3 can be rotated within the range of 0°-180° on the connecting column 2. The rotated foldable protective handle 3 can be kept fixed at the current angle through the limiting mechanism, and it is more labor-saving to control the wrench body 1 to rotate the bolts and nuts through the fixed foldable protective handle 3.

[0030] Specifically, the limiting mechanism includes a gap gear 51, which is fixedly connected to the connecting column 2, and a fixed block 52 is fixedly connected to the inner surface of the folding protection handle 3. A plug rod 53 is slidably inserted on the fixed block 52, and one end of the plug rod 53 is fixedly connected to a limiting plug block 54, and the limiting plug block 54 is clamped with the gap gear 51. A spring 55 is sleeved on the outer surface of the plug rod 53, and the spring 55 is located between the limiting plug block 54 and the fixed block 52. A slideway 56 is excavated on the folding protection handle 3, and a push block 57 is fixedly connected to the limiting plug block 54, and the push block 57 moves through the slideway 56 to the outside of the folding protection handle 3.

[0031] In this embodiment, when the folding protective handle 3 is rotated, the rotating handle 4 covers the outer surface of the folding protective handle 3, and the push block 57 is pushed to slide in the slide 56, so that the limit block 54 and the insertion rod 53 slide on the fixed block 52, and the limit block 54 is away from the gap gear 51 and compresses the spring 55. When the limit block 54 is not plugged into the gap gear 51, the rotation of the folding protective handle 3 is not restricted, so that it can be rotated on the connecting column 2. After the folding protective handle 3 is rotated to a suitable position, the push block 57 is released, and the elastic force of the spring 55 itself resets the limit block 54. The limit block 54 is plugged into the gap gear 51 to limit the folding protective handle 3, so that the folding protective handle 3 is fixed. The rotation of the wrench body 1 is controlled by the fixed folding protective handle 3, which saves more effort for screws and screw twisting.

[0032] Specifically, the folding protection handle 3 and the rotating handle 4 are both fixedly connected with a magnetic strip 6 , and the two magnetic strips 6 are magnetically connected.

[0033] In this embodiment, when the folding protective handle 3 is folded on the wrench body 1, the rotating handle 4 rotates on the folding protective handle 3. The rotating handle 4 cooperates with the folding protective handle 3 to protect the digital display device on the wrench body 1. After the rotating handle 4 is rotated, the two magnetic strips 6 will contact each other. The two magnetic strips 6 are magnetically connected to keep the rotating handle 4 stable.

[0034] Specifically, the outer surface of the connecting column 2 is fixedly connected to the limited rotation block 7 , and the limited rotation block 7 corresponds to the folding protection handle 3 .

[0035] In this embodiment, the rotation limit block 7 limits the folding protection handle 3 so that the folding protection handle 3 can rotate to a maximum of 180°. This prevents excessive rotation from affecting the use of the digital torque wrench.

[0036] Specifically, an observation window 8 is provided on the foldable protective handle 3 , and the observation window 8 corresponds to the wrench body 1 .

[0037] In this embodiment, the observation window 8 allows the torque value to be observed when the foldable protective handle 3 is folded on the wrench body 1, so that the wrench body 1 can also be used after the foldable protective handle 3 is folded.

[0038] Working principle: When the digital torque wrench is in use, the rotating handle 4 is rotated to the outer surface of the folding protective handle 3, and then the push block 57 is pushed to slide in the slideway 56, so that the limit plug 54 and the plug rod 53 slide on the fixed block 52, and the limit plug 54 is away from the gap gear 51 and compresses the spring 55. When the limit plug 54 is not plugged into the gap gear 51, the rotation of the folding protective handle 3 is not restricted, so that it can rotate on the connecting column 2, and the folding protective handle 3 is rotated to a suitable position. After that, by loosening the push block 57, the elastic force of the spring 55 itself resets the limit plug 54, and the limit plug 54 is inserted into the gap gear 51 to limit the folding protective handle 3, so that the folding protective handle 3 is fixed. By controlling the rotation of the wrench body 1 through the fixed folding protective handle 3, it is more labor-saving to twist the bolts and nuts. When the digital torque wrench is not in use, the push block 57 is pushed again to make the folding protective handle 3 rotate to the wrench body 1 for folding. The folding protective handle 3 cooperates with the rotating handle 4 to protect the wrench body 1.

[0039] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the utility model according to the technical solution and improved ideas of the utility model, which should be included in the protection scope of the utility model.
