They are suitable for power such as nuclear power, wind power, hydropower, thermal power, as well as shipping, metallurgy, transportation, cement, construction, aviation and other fields. It is a professional bolt tightening tool that uses hydraulic power to provide high torque output and is used for the installation and removal of bolts. It is generally composed of a hydraulic torque wrench body, a hydraulic torque wrench special The patent, CN214081178U, discloses a dual-head hydraulic wrench, comprising a main hydraulic wrench body, a first wrench head, and a second wrench head. The main hydraulic wrench body comprises a connecting block at its upper end, each of which houses a blocking block. The blocking blocks are provided at their left and right ends, respectively, with a first baffle and a second baffle. A retaining spring is provided between the first and second baffles.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 3 The utility model provides a technical solution: a double-head hydraulic wrench, including a hydraulic wrench body 1, the hydraulic wrench body 1 includes two wrench heads 3, a connecting groove 2 is opened in the wrench head 3, a first connecting plate 5 and a second connecting plate 6 are installed between the two wrench heads 3, and sliders 8 are installed at the ends of the first connecting plate 5 and the second connecting plate 6. An auxiliary plate 11 is installed on the slider 8, and an auxiliary head 13 is installed in the auxiliary plate 11. The auxiliary head 13 corresponds to the connecting groove 2, and a blocking plate 12 is installed on the auxiliary plate 11.

[0021] In this embodiment, a hydraulic connecting head 4 is installed on the hydraulic wrench body 1, a slide groove 7 is opened on the side of the wrench head 3, a slider 8 corresponds to the slide groove 7, a groove is opened in the slider 8, and a mounting rod 10 is elastically fitted in the groove. The mounting rod 10 is fixedly connected to the auxiliary plate 11 by bolts.

[0022] Specifically, the slider 8 can be slid, and the slider 8 slides in the slide groove 7, thereby driving the installation rod 10 to slide, so that the installation rod 10 drives the auxiliary plate 11 to slide, and the auxiliary plate 11 can be moved away from the connecting groove 2, and the connecting groove 2 can be fully opened.

[0023] A spring 9 is fixed between the mounting rod 10 and the groove wall of the groove.

[0024] Specifically, the mounting rod 10 is pulled upwards, so that the spring 9 is stretched, thereby driving the auxiliary plate 11 to move upwards, preventing the connecting groove 2 from limiting the auxiliary head 13 .

[0025] The auxiliary plate 11 is rotatably connected to the auxiliary head 13 , one end of the auxiliary head 13 is located in the connecting groove 2 , friction lines are provided in both the auxiliary head 13 and the connecting groove 2 , the auxiliary plate 11 is rotatably connected to the blocking plate 12 , and the blocking plate 12 is located above the auxiliary head 13 .

[0026] Specifically, the auxiliary head 13 can be completely blocked by the blocking plate 12 to prevent dust from entering the auxiliary head 13 and the connecting slot 2. In addition, the auxiliary head 13 can be inserted into the connecting slot 2 to change the diameter of the connecting slot 2 and expand the scope of application of the device.

[0027] Magnetic blocks 16 are fixed to the ends of the first connecting plate 5 and the second connecting plate 6 , and the two magnetic blocks 16 correspond to each other. A clamping block 14 is fixed to one of the magnetic blocks 16 , and a clamping slot 15 is provided on the other magnetic block 16 , and the clamping block 14 corresponds to the clamping slot 15 .

[0028] When it is necessary to open one of the connecting slots 2 separately, the first connecting plate 5 or the second connecting plate 6 can be pried to make the clamping block 14 lose the clamping relationship with the clamping slot 15, so that one of the sliders 8 can be slid separately to open one of the connecting slots 2 separately, which is convenient for the use of the hydraulic wrench body 1.

[0029] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
