[0002] Torque value is crucial for the use of hydraulic wrenches, but most of the existing hydraulic wrenches need to test the torque value conventionally. They need to get the pressure value MPa through testing on the hydraulic press, and then use the torque calibration wrench to calibrate the torque value Nm, and then adjust the torque according to the value, which requires repeated calibration. In the existing public technology, the Chinese utility model patent with publication number 201821444637.X proposes a digital display hydraulic pulse wrench, which uses an induction gasket installed on the main shaft to transmit magnetic permeability, and then uses a sensor and a data cable to transmit it to the terminal controller. The terminal controller is designed to convert the numerical mode to display the torque value in front of the user, with intelligent display and accurate reading.

[0025] A U-shaped fixing frame 4 is provided at the upper end of the oil pressure pulse wrench body 1, and both sides of the U-shaped fixing frame 4 are fixedly connected to the oil pressure pulse wrench body 1 through fixing screws 5. A seat rod 8 is provided at the upper end of the U-shaped fixing frame 4, and a through hole 9 is opened in the middle position of one side of the seat rod 8. A hole sleeve 10 is fixedly connected to the outer side of the through hole 9, and a limit clamping shaft 11 is movably connected inside the hole sleeve 10. The front end surface of the limit clamping shaft 11 is an inclined surface, and a spring 12 is fixedly connected between the rear end of the limit clamping shaft 11 and the rear end of the hole sleeve 10;

[0026] A bottom shell 13 is provided at the bottom end of the terminal controller 3, and the front and rear ends of both sides of the bottom shell 13 are fixedly connected to the terminal controller 3 by fixing screws 14. The bottom shell 13 is integrally formed with a clamping rod 15, and the clamping rod 15 is clamped and connected with the seat rod 8. The lengths of the bottom shell 13, the clamping rod 15 and the seat rod 8 are equal. A limiting clamping hole 16 is provided in the middle position of one side of the clamping rod 15, and the front end of the limiting clamping shaft 11 is clamped and connected with the limiting clamping hole 16. Among them, through the arrangement and coordination of the above-mentioned structure, the terminal controller 3 can be further fixedly installed on the oil pressure pulse wrench body 1, and the assembly and disassembly is simple and the fixation is stable.

[0027] In the present embodiment, the utility model is provided with a U-shaped fixing frame 4, a seat rod 8 and a limit clamping shaft 11 on the oil pressure pulse wrench body 1, and a bottom shell 13 and a clamping rod 15 are provided at the bottom end of the terminal controller 3. The terminal controller 3 is connected to the oil pressure pulse wrench body 1 through a data cable 2, and is further fixedly installed on the oil pressure pulse wrench body 1 through the clamping cooperation of the clamping rod 15, the seat rod 8 and the limit clamping shaft 11. This can effectively prevent the terminal controller 3 from swinging when the oil pressure pulse wrench body 1 is in use, thereby affecting the use of the terminal controller 3 and the oil pressure pulse wrench body 1. The utility model is simple and convenient, and has better use.

[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, further, a seat cover 6 is fixedly connected to the middle position of the upper end of the U-shaped fixing frame 4, and a rotating shaft 7 is rotatably connected inside the seat cover 6, and the upper end of the rotating shaft 7 is fixedly connected to the bottom end of the seat rod 8, wherein, when the rotating shaft 7 rotates relative to the seat cover 6, because the rotation of the rotating shaft 7 relative to the seat cover 6 has a certain friction resistance, the rotating shaft 7 can be fixed after the rotation adjustment, and the terminal controller 3 can be prevented from rotating on its own.

[0029] In this embodiment, the utility model is further provided with a seat cover 6 and a rotating shaft 7 between the U-shaped fixing frame 4 and the seat rod 8. When in use, the rotating shaft 7 is rotated relative to the seat cover 6 to flexibly adjust the use angle of the terminal controller 3, so that the numerical value on the terminal controller 3 can be read and used when used at different angles. It is simple and convenient to use and has better performance.

[0030] The use process and working principle of the utility model are as follows: when in use, the terminal controller 3 electrically connected to the oil pressure pulse wrench body 1 through the data line 2 is further fixedly installed on the oil pressure pulse wrench body 1, and the specific operation is as follows: first, the clamping rod 15 at the bottom end of the terminal controller 3 is laterally inserted into the seat rod 8 from one side of the seat rod 8. During the insertion of the clamping rod 15 relative to the seat rod 8, the front end of the limit clamping shaft 11 is squeezed by the inserted clamping rod 15, and the front end of the limit clamping shaft 11 is temporarily retracted into the through hole 9, and the spring 12 is elastically stretched. After the clamping rod 15 is inserted into place relative to the seat rod 8, the limit clamping hole 16 is aligned with the through hole 9, and the squeezing force on the front end of the limit clamping shaft 11 disappears. Under the rebound force of the spring 12, the limit clamping shaft 11 rebounds by itself, and the limit The front end of the positioning clamp shaft 11 automatically pops out of the through hole 9 and is clamped in the limiting clamp hole 16 to further limit and fix the clamp rod 15 after being inserted into place, thereby completing the further fixed installation of the terminal controller 3 on the oil pressure pulse wrench body 1. After that, the use angle of the terminal controller 3 can be further adjusted by rotating the rotating shaft 7 relative to the seat cover 6. Since the rotation of the rotating shaft 7 relative to the seat cover 6 has a certain friction resistance, the rotating shaft 7 can be fixed after the rotation adjustment, which can prevent the terminal controller 3 from rotating on its own. Finally, the oil pressure pulse wrench body 1 can be started for corresponding use. Among them, the specific connection and use of the oil pressure pulse wrench body 1, data cable 2, and terminal controller 3 are existing public technologies and will not be further described here.

[0031] In addition, the contents not described in detail in this embodiment are all prior art and common knowledge.

[0032] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
