The torque rod 6 is used to support the arc block 61. The arc block 61 is used to support the driving member 62 and the fixed rod 63, which is convenient for the staff to operate the torque wrench.

[0022] See Figures 1 to 3, in a further embodiment, the sensor 22, the signal transmitter 23, and the display screen 4 are all connected to the data processor 21 through lines. The signal transmitter 23 is also connected to the driving member 62 and the alarm 5 through lines. The data processor 21 serves as the center. The data processor 21 controls each module by receiving and transmitting level signals. The sensor 22, the signal transmitter 23, and the display screen 4 are all prior arts and will not be elaborated in this specification.

[0023] See Figures 1 to 3 , in a further embodiment, the adjustment keys 3 are divided into a value increase key, a value zeroing key, a value decrease key, and several value auxiliary keys. Each value auxiliary key is disposed on one side of the value increase key, and different values are provided on the value auxiliary keys. The sensor 22 is disposed below the adjustment key 3. There are several sensors 22, and each adjustment key 3 is connected to the corresponding sensor 22. When it is necessary to adjust the torque value, the staff presses the value increase key. The value increase key transmits a level signal to the data processor 21 through the sensor 22. The data processor 21 transmits a level signal to the display screen 4, and the display screen 4 displays the increased value. When a larger set value is required, the staff can press the corresponding value auxiliary key. The values on each value auxiliary key are different. After the staff presses the required value auxiliary key and then presses the value increase key, the data processor 21 will increase the value corresponding to the value auxiliary key. When the adjusted value is greater than the predetermined value, the value is decreased by pressing the value decrease key. The values of the value auxiliary keys can be set according to actual needs and will not be elaborated in this specification.

[0024] See Figures 1 to 3 , in a further embodiment, after the value is adjusted, the data processor 21 transmits a level signal to the signal transmitter 23. The signal transmitter 23 transmits a level signal to the driving member 62. The output shaft of the driving member 62 rotates, driving the fixed rod 63 to rotate. The fixed rod 63 drives the corresponding connecting member to rotate, thereby completing the fastening. When the fixed rod 63 completes the fastening, the alarm 5 will emit a sound and transmit a signal to the signal transmitter 23. The signal transmitter 23 causes the driving member 62 to stop working. After the fastening is completed, the staff can press the value zeroing key to zero the data for convenient next use.

[0025] See Figures 1 to 3In a further embodiment, one end of the fixing rod 63 is provided with a plurality of blocks, and the blocks on the fixing rod 63 are used to cooperate with the connecting piece to drive the connecting piece to rotate and complete the fixation. The connecting piece is a connecting piece between the torque wrench and the fixing piece, which is a prior art and is used to assist in the fixation of the torque wrench. It will not be repeated in this specification. The other end of the fixing rod 63 is fixedly connected to the output shaft of the driving piece 62, and the output shafts of the fixing rod 63 and the driving piece 62 are both rotatably connected to the arc block 61.

The driving member 62 is a rotating motor.

[0027] During the implementation of the utility model: when the torque value needs to be adjusted, the staff presses the value increase key, and the value increase key transmits the level signal to the data processor 21 through the sensor 22, and the data processor 21 transmits the level signal to the display screen 4, and the display screen 4 displays the increased value. When the set value needs to be larger, the staff can press the corresponding value auxiliary key, and the values ​​on each of the value auxiliary keys are different. The staff presses the required value auxiliary key and then presses the value increase key, then the data processor 21 will increase the value corresponding to the value auxiliary device. When the adjusted value is greater than the predetermined value, the value of the value auxiliary key is increased. When the value is adjusted, the value can be reduced by pressing the value reduction key. After the value is adjusted, the data processor 21 transmits a level signal to the signal transmitter 23, and the signal transmitter 23 transmits a level signal to the driver 62. The output shaft of the driver 62 rotates, driving the fixing rod 63 to rotate, and the fixing rod 63 drives the corresponding connecting member to rotate, thereby completing the tightening. When the fixing rod 63 completes the tightening, the alarm 5 will sound and transmit a signal to the signal transmitter 23, and the signal transmitter 23 stops the driver 62 from working. After the tightening is completed, the staff can press the value reset key to reset the data to zero for easy use next time.
