[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides a digital display torque wrench with multi-parameter input function as shown in Figures 1-4 which includes a rod body 1 and a wrench head 3. A clamping groove 4 is formed at the end of the rod body 1. A clamping block 5 is fixedly connected to the wrench head 3, and the clamping block 5 is inserted and matched with the clamping groove 4. Both the clamping groove 4 and the clamping block 5 are set as square structures. After the wrench head 3 is inserted into the inside of the clamping groove 4 through the clamping block 5, relative rotation can be prevented.

[0022] A handle 2 is fixedly connected to the end of the rod body 1 away from the wrench head 3. The handle 2 is provided to facilitate the use of the torque wrench.

[0023] To realize the connection between the clamping block 5 and the clamping groove 4, a limiting block 6 is fixedly connected to the end of the clamping block 5 away from the wrench head 3. A first square groove 7 is formed on the limiting block 6, a second square groove 8 is formed on the inner wall of the clamping groove 4, and a third square groove 9 is formed on the outer wall of the rod body 1. The third square groove 9 is communicated with the second square groove 8. The length and width of the second square groove 8 are both larger than those of the third square groove 9. A sliding column 10 is slidably connected to the inside of the third square groove 9. One end of the sliding column 10 located inside the clamping groove 4 is fixedly connected with a square block 11, and the square block 11 is inserted and matched with the first square groove 7. Both the square block 11 and the first square groove 7 are set as square structures. After the square block 11 is inserted into the inside of the first square groove 7, the position of the limiting block 6 is limited to prevent sliding. The square block 11 and the first square groove 7 are set and are square structures, and at the same time the first square groove 7 penetrates through the limiting block 6, which has obvious stability compared with the spring bean in the prior art.

[0024] A spring 12 is sleeved outside the sliding column 10. One end of the spring 12 is fixedly connected to the square block 11, and the other end of the spring 12 is fixedly connected to the inner wall of the second square groove 8.

[0025] A pull plate 13 is fixedly connected to the end of the sliding column 10 away from the square block 11. The pull plate 13 is provided to limit the third square groove 9. In the specific use process, a structure such as a lifting ring cooperating with the pull plate 13 can be set. When it is necessary to remove the wrench head 3, the sliding column 10 can be pulled upward through the lifting ring and the pull plate 13, so that the square block 11 moves upward synchronously.

[0026] To facilitate the quick installation of the wrench head 3 on the rod body 1, a first notch 14 is formed at the end of the square block 11 away from the sliding column 10. The first notch 14 is located on the side of the square block 11 close to the clamping block 5. A second notch 15 is formed at the end of the limiting block 6 away from the clamping block 5. The first notch 14 cooperates with the second notch 15.

[0027] During installation and use, the wrench head 3 is inserted into the inside of the card slot 4 through the clamping block 5. Under the cooperation of the first notch 14 and the second notch 15, the limiting block 6 squeezes the square block 11 to slide upward, and compresses the spring 12 to contract. When the square block 11 corresponds to the first square groove 7, the reset elastic force of the spring 12 causes the square block 11 to be inserted into the inside of the first square groove 7, limiting the position of the limiting block 6, completing the assembly of the wrench head 3 and the rod body 1, with convenient operation and high stability.

[0028] At the same time, by selecting a spring 12 with appropriate elasticity, the square block 11 will not move randomly.

[0029] During disassembly, the sliding column 10 is pulled upward through the pull plate 13, causing the square block 11 to move upward synchronously. The square block 11 is withdrawn from the inside of the first square groove 7, releasing the restriction on the limiting block 6, and the disassembly is convenient.

[0030] By setting structures such as the card slot 4, the clamping block 5, the limiting block 6, the first square groove 7 and the square block 11, when the square block 11 corresponds to the first square groove 7, the reset elastic force of the spring 12 causes the square block 11 to be inserted into the inside of the first square groove 7, limiting the position of the limiting block 6, completing the assembly of the wrench head 3 and the rod body 1, with convenient operation and high stability.

[0031] A digital display device 16 is fixedly arranged on the rod body 1. The digital display device 16 includes structures such as a display screen and an indicator light. Specifically, an operating system is arranged inside the digital display device 16, including a parameter input and display module, a two-dimensional code scanning module, a data sending module, etc., and cooperates with structures such as a motor, a torque sensor, and a rotation angle sensor on the wrench.

[0032] The parameter input and display module is used to preset tightening parameters, display tightening results, and prompt operation information; the parameters include: preset torque, bolt batch number, bolt average torque coefficient, etc.; the two-dimensional code scanning module is used to identify the current operator; the data sending module is used to send operation instructions to structures such as the motor. The parameter input and display module, the two-dimensional code scanning module, the data sending module, etc. are all common existing technologies and will not be elaborated here.
