[0027] Embodiment:

[0028] Please refer to Figures 1-4, a new type of mechanical torque wrench, including a wrench body 1. The wrench body 1 includes a main rod 101, a turning head 102 and a connecting pillar 103. The turning head 102 is detachably connected to one end of the main rod 101, and the connecting pillar 103 is fixedly connected to the other end of the main rod 101. A fixing piece 2 is fixedly connected to the circumferential surface of the connecting pillar 103. A folding handle 3 is arranged inside the fixing piece 2. Two circular bumps 4 are fixedly connected inside the fixing piece 2. Two sliding rotation grooves 5 are drilled on the circumferential surface of the folding handle 3, and the two circular bumps 4 are respectively located in the two sliding rotation grooves 5. A jack 6 is drilled on the connecting pillar 103, and the jack 6 corresponds to the folding handle 3.

[0029] In this embodiment, when the mechanical torque wrench is in use, first, the folding handle 3 rotates through the two sliding rotation grooves 5 and the two circular bumps 4, so that one end of the folding handle 3 corresponds to the jack 6. The folding handle 3 slides into the jack 6 through the two circular bumps 4 and the two sliding rotation grooves 5 and penetrates the connecting pillar 103, cooperating with the main rod 101 and the turning head 102 to loosen and tighten the fastener. The penetration length of the folding handle 3 can be adjusted according to the usage situation, enabling the staff to use it with both hands. When the staff uses it with one hand, by adjusting the length, it can be more labor-saving when rotating.

[0030] Specifically, a limiting piece 7 is fixedly connected to the top end of the fixing piece 2, and the limiting piece 7 corresponds to the folding handle 3.

[0031] In this embodiment, the limiting piece 7 is used to limit the rotation angle of the folding handle 3. When the folding handle 3 rotates to correspond to the jack 6, the limiting piece 7 restricts the folding handle 3, enabling the folding handle 3 to accurately insert into the jack 6.

[0032] Specifically, a threaded knob 8 is threadedly connected to the end of the connecting pillar 103 away from the main rod 101, and one end of the threaded knob 8 corresponds to the jack 6.

[0033] In this embodiment, after the folding handle 3 is inserted into the jack 6, the folding handle 3 is positioned by rotating the threaded knob 8, so that the insertion length of the folding handle 3 remains stable, preventing the folding handle 3 from sliding when driving the connecting pillar 103 to rotate.

[0034] Specifically, anti-slip lines 9 are engraved on the circumferential surface of the folding handle 3, and the anti-slip lines 9 correspond to one end of the threaded knob 8.

[0035] In this embodiment, the threaded knob 8 can increase the friction with the folding handle 3 through the anti-slip lines 9, further improving the stabilizing effect on the folding handle 3.

[0036] Specifically, one end of the folding handle 3 is detachably connected with a handle 10. One end of the handle 10 is fixedly connected with a threaded rod 11, and the threaded rod 11 is threadedly connected inside the folding handle 3.

[0037] In this embodiment, when a staff member uses it with one hand, the handle 10 is installed at one end of the folding handle 3 through the threaded rod 11, making it more convenient for the staff member to rotate the folding handle 3.

[0038] Working principle: When a mechanical torque wrench is in use, first, the folding handle 3 rotates through the two sliding grooves 5 and the two circular bumps 4, so that one end of the folding handle 3 corresponds to the jack 6. The folding handle 3 slides into the jack 6 through the two circular bumps 4 and the two sliding grooves 5 and penetrates the connecting pillar 103, and cooperates with the main rod 101 and the wrench head 102 to tighten or loosen the fastener.

[0039] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
