The staff pulls the pull block 8 to drive the slide plate 6 to move, and the slide plate 6 drives the plug rod 9 to release the limit between the plug hole 10, so that the fixation of the limit block 4 is released, the staff moves the limit block 4 downward to hook the hanger body 1 and the excavator boom, and moves the limit block 4 upward to align the plug rod 9 with the plug hole 10, and the staff pushes the pull block 8 to fix the position of the spring groove 3 to avoid falling off and damage when the staff hooks the excavator boom.

[0023] Reference Figure 3 and 4 As shown, in this implementation scheme: the right end of the slide plate 6 is fixedly connected with a force storage spring 11, the number of force storage springs 11 is two and both are fixedly connected to the right end of the slide plate 6, the right end of the force storage spring 11 is fixedly connected to the right end of the inner cavity of the adjustment box 5, when the staff pulls the pull block 8, the pull rod 7 and the slide plate 6 are driven to move to the right, the slide plate 6 squeezes the force storage spring 11 to compress and store force, and at the same time releases the limit between the insertion rod 9 and the socket 10, when the staff aligns the insertion rod 9 with the socket 10 and releases the pull block 8, the slide plate 6 is quickly pushed to the left under the action of the rebound force of the force storage spring 11, and drives the insertion rod 9 to be inserted into the socket 10 for limiting.

[0024] Reference Figure 4As shown, in the present embodiment: the front end and the rear end of the inner cavity of the regulating box 5 are both provided with a slide groove 12, the front end and the rear end of the slide plate 6 are both fixedly connected with a slider 13, the surface of the slider 13 is slidably connected with the inside of the slide groove 12, and when the staff moves the slide plate 6, the slide plate 6 drives the slider 13 to slide inside the slide groove 12, and the movement trajectory of the slide plate 6 is fixed by the setting of the slide groove 12 and the slider 13, and at the same time, the jamming caused by the misalignment of the slide plate 6 during the movement is avoided.

[0025] Reference Figure 2 As shown, in this implementation scheme: the bottom end of the spring groove 3 is fixedly connected with a thrust spring 14, and the top end of the thrust spring 14 is fixedly connected to the bottom end of the limit block 4. When the staff moves the limit block 4 downward, the thrust spring 14 is squeezed to compress and accumulate force. When the staff hooks the sling body 1 with the excavator boom, the limit block 4 is released, and the limit block 4 moves rapidly upward to be limited under the action of the rebound force of the thrust spring 14.

[0026] Reference Figure 5 As shown, in this embodiment: the front end and the rear end inside the spring groove 3 are both provided with sliding grooves 15, the front end and the rear end of the limit block 4 are both fixedly connected with sliding blocks 16, the surface of the sliding block 16 is slidably connected with the inside of the sliding groove 15, and the staff drives the sliding block 16 to slide inside the sliding groove 15 during the process of moving the limit block 4. The moving trajectory of the limit block 4 is fixed by the setting of the sliding groove 15 and the limit block 4 is prevented from falling off and being damaged.

[0027] Reference Figure 2 As shown, in the present embodiment: a pressure column 17 is slidably connected inside the sling body 1, a pressure block 18 is fixedly connected to the bottom of the pressure column 17, a threaded rod 19 is rotatably connected to the front end of the sling body 1, a threaded hole 20 is provided on the surface of the pressure column 17, and the surface of the threaded rod 19 is rotatably connected to the inside of the threaded hole 20.

[0028] Reference Figure 1 As shown, in this embodiment: the material of the sling body 1 is aluminum alloy. By setting the sling body 1 as aluminum alloy, the rigidity of the sling body 1 can be better used for hook lifting operations, thereby increasing the load-bearing capacity.

[0029] When the staff member aligns the plug rod 9 with the socket 10 and releases the pulling block 8, the sliding plate 6 is quickly pushed to the left under the action of the rebound force of the force storage spring 11, and the plug rod 9 is inserted into the socket 10 for limiting. In the process of moving the sliding plate 6, the sliding plate 6 drives the slider 13 to slide inside the slide groove 12, and passes through the slide groove 12 The setting of the slider 13 fixes the moving trajectory of the slide plate 6 and avoids the slide plate 6 from getting stuck due to misalignment during movement. When the staff makes the limit block 4 move downward, it squeezes the thrust spring 14 to compress and accumulate force. When the staff hooks the sling body 1 with the excavator boom, the limit block 4 is released. Under the action of the rebound force of the thrust spring 14, the limit block 4 quickly moves upward for limiting.
