In this embodiment, the connection and engagement of the hydraulic cylinder 162, the transmission lever 163, the grip 164, and the actuating lever 165 are the same as those of the structure of the hydraulic jaw puller, but in this embodiment, the jaws are not provided in the pressing member 160, and the base 161 is provided, so that the entire pressing member 160 can be attached to the first and

second brackets

110 and 120.

Specifically, the actuating lever 165 extends into the accommodating space formed by the first fulcrum plate 110 and the second fulcrum plate 120, and can abut against the deformed position of the hook lifting lever, and the actuating lever 165 can be moved forward or backward by manually operating the grip handle 164, and when the actuating lever is moved forward, a pressing force can be applied to the deformed position of the hook lifting lever, so that the hook lifting lever can be bent and corrected in the shape defined by the limit pin 140 and the actuating lever 165. In this embodiment, the hydraulic cylinder 162, the transmission rod 163, the grip 164 and the start rod 165 may be directly assembled with the base 161 by using an existing hydraulic puller, or may be separately fabricated and assembled. The whole tool is about 12 kg in weight, convenient to carry, suitable for single independent operation, free of requirements on operation environment, time-saving and labor-saving, and capable of achieving the effect of quickly bending.

Further, referring to fig. 2, the end of the actuating lever 165 remote from the hydraulic cylinder 162 is provided with a recess 166 for pressing against the hook lifting lever. The cross-sectional shape of the groove 166 is a single-segment arc or a multi-segment spliced arc, and can be matched with the shape of the hook lifting rod to partially clamp and limit the hook lifting rod, so that the contact area between the starting rod 165 and the hook lifting rod is increased, and the hook lifting rod is prevented from being displaced in the process of applying a pressing force.

Referring to fig. 1 and 2, in order to facilitate the connection between the base 161 and the hydraulic cylinder 162, as a specific embodiment, the pressing member 160 further includes a sleeve 167 connected to the hydraulic cylinder 162, the base 161 is sleeved outside the sleeve 167, and the base 161 is in threaded engagement with the sleeve 167. The sleeve 167 is connected to the hydraulic cylinder 162 in the same manner as the sleeve 167 and the hydraulic cylinder 162 are connected to a jaw hydraulic puller, it being understood that the sleeve 167 is connected to the housing of the hydraulic cylinder 162 and is not driven. The actuating rod 165 is inserted into the sleeve 167 and can be extended and retracted by the hydraulic cylinder 162, thereby applying a pressing force to the deformed position of the hook lifting rod. In this embodiment, the base 161 is threadedly engaged with the sleeve 167 to facilitate replacement and repair of the base 161.

Referring to fig. 1 and 2, in order to connect the base 161 to the first plate 110 and/or the second plate 120, as an embodiment, the first plate 110 and the second plate 120 are provided with at least two shackles 180 arranged at intervals, and the base 161 is erected on the shackles 180. In this embodiment, the base 161 is connected to the first plate 110 and the second plate 120 by shackles 180. Shackle 180 includes a hanging ring 182 and a bolt 184, and is typically a D-shackle. The shackle 180 can be disassembled to realize the compression of the piece 160, so that the whole tool is of a detachable structure and can be carried conveniently. In addition, the base 161 is detached from the first support plate 110 and the second support plate 120, so that the first support plate 110 and the second support plate 120 form an opening, the first support plate 110 and the second support plate 120 can be directly hung and sleeved at the deformation position of the hook lifting rod by using the opening, the hook lifting rod does not need to be detached, the bending process is simplified, and then the base 161 is installed on the shackle 180, so that the whole pressing piece 160 can be installed on the first support plate 110 and the second support plate 120, and the hook lifting rod is limited in the accommodating cavity 170.

Further, referring to fig. 1, the base 161 has a first arm and a second arm symmetrically disposed, and the first arm and the second arm are disposed on the corresponding shackle 180. Specifically, the first arm and the second arm are both mounted on the corresponding hanging ring 182, and the first arm and the second arm are symmetrically arranged with respect to the axial direction of the starting rod 165, and can be better fitted with the hanging ring 182, and can also be reduced in weight and light and portable compared with the plate-like shape, the block-like shape, and the like.

To ensure that the base 161 does not detach from the shackle 180 during a turndown, the shackle 180 includes, as a specific embodiment, a suspension loop 182 having a slip-resistant pattern, the suspension loop 182 engaging the first and second arms. First arm and second arm cooperate with different link 182 respectively, because the existence of anti-skidding decorative pattern, when first arm and second arm frame located different link 182, rely on great frictional force for first arm and second arm are difficult to break away from link 182, and then make base 161 can not break away from shackle 180, thereby make when exerting the pressure effort, actuating lever 165 can not break away from the hook lifting lever, guarantee that actuating lever 165 can exert the pressure effort that is used for transferring the turn to the hook lifting lever constantly.

As another embodiment, the portions of the first and second arms that extend beyond shackle 180 are provided with locking members. When the first arm and the second arm support are arranged on the shackle 180, specifically on the hanging ring 182, locking members are arranged on the parts of the first arm and the second arm exceeding the corresponding hanging ring 182, and the locking members can be limiting nuts in threaded fit with the first arm and the second arm, or ropes or wires for binding the first arm and the second arm with the corresponding hanging ring 182 respectively. Of course, other types of locking members are possible and not limiting.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
