[0021] Please refer to Figures 1 to 5 As shown in the drawings, the present application discloses a torque wrench structure 100 with wireless transmission torque value, which comprises:

[0022] A pipe body 10, which has a container groove 11 inside and a handle 12 at the rear end, the handle 12 can rotate at the rear end of the container groove 11, and the handle 12 is provided with a torsion adjusting seat 13, which can move forward and backward in the container groove 11 with the rotation of the handle 12, and the container groove 11 is provided with a resilient element 14, one end of the resilient element 14 is in contact with the torsion adjusting seat 13, and the outer wall of the rear end of the pipe body 10 is provided with a long hole 15, and the front end of the pipe body 10 is fixed with a torsion wrench head 16.

[0023] A trip alarm device 20 is arranged in the container groove 11 of the pipe body 10, which includes an upper jaw 21, a lower jaw 22, a trip pad 23, a needle height adjusting sleeve 24 and a trip detection needle 25, the front end of the upper jaw 21 is connected to the torsion wrench head 16, the rear end of the upper jaw 21 has a shallow groove 211, the front end of the lower jaw 22 is provided with a groove 221 corresponding to the shallow groove 211, and a through hole 222 is arranged in the center axis, and the rear end of the lower jaw 22 is in contact with the other end of the resilient element 14, the trip pad 23 is arranged between the upper jaw 21 and the lower jaw 22, and the two end faces are in contact with the shallow groove 211 and the groove 221 respectively, the needle height adjusting sleeve 24 is arranged in the through hole 222 of the lower jaw 22, and the trip detection needle 25 is arranged in the needle height adjusting sleeve 24 and contacts the trip pad 23, the trip detection needle 25 has a wire 251.

[0024] Wherein, through the position change of the torsion adjusting seat 13 in the container groove 11 of the pipe body 10, the elastic force of the resilient element 14 on the lower jaw 22 can be adjusted, the closer the torsion adjusting seat 13 is to the lower jaw 22, the greater the elastic force of the resilient element 14 will be.

[0025] A Bluetooth circuit board 30 is arranged outside the pipe body 10 and is electrically connected to the trip detection needle 25, more specifically, the trip detection needle 25 is connected to the Bluetooth circuit board 30 through the long hole 15 of the pipe body 10, the Bluetooth circuit board 30 can wirelessly transmit the set torque value to a receiving end (not shown) through Bluetooth wireless transmission, the receiving end can be a smart phone or a computer, so as to synchronize the display or store the record torque setting value.

[0026] The specific operation process is as follows, referring to Figure 6 and with Figure 5As shown, before operation, the present application can be rotated by the handle 12, so that the torsion adjusting seat 13 pushes against the elastic element 14 in the pipe body 10, and the elastic compression force of the elastic element 14 is used to adjust the torsion value. The elastic element 14 is pressed against the lower clamping jaw 22, so that the upper clamping jaw 21 and the lower clamping jaw 22 clamp the escape pad 23, and the escape detection needle 25 contacts the escape pad 23 to transmit a signal.

[0027] Referring to Figure 7 and in combination with Figure 2 As shown, at this time, an action of loosening or tightening can be performed on a screw (not shown) by applying an action force to the screw through the torsion wrench head 16, and at the same time, the torsion wrench head 16 also generates a reverse action force. When the action force of the torsion wrench head 16 between the upper clamping jaw 21 and the lower clamping jaw 22 is too large (the screw reaches the set torsion value), the escape pad 23 is separated from the shallow groove 211 of the upper clamping jaw 21 and the groove 221 of the lower clamping jaw 22, and at the moment when the escape detection needle 25 is separated from the escape pad 23, an escape signal is sent. The escape signal is transmitted back to the Bluetooth circuit board 30, the Bluetooth circuit board 30 processes the escape signal into a digital torsion value, and then transmits the escape signal to the receiving end by a Bluetooth wireless transmission mode, so as to synchronously display or store and record the torsion value.
