Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 , the utility model provides a technical solution:

[0019] A lifting tool comprises a connecting plate 1, wherein convex blocks 2 are provided at both ends of the connecting plate 1 through fixing members 3. By using the fixing members 3, the connecting plate 1, the second cross bar 6 and the first cross bar 4 can be quickly fixed together, thereby realizing the rapid installation of the lifting tool, and at the same time, it is also convenient for the rapid disassembly of the lifting tool, thereby facilitating the transportation of the lifting tool; a cross bar 4 is provided on one side of one of the convex blocks 2, and a cross bar 2 6 is provided on the other convex block 2, and a connecting head 7 is provided at one end of the second cross bar 6, and an impeller connecting plate 8 is installed on the connecting head 7, so that the impeller can be installed on the impeller connecting plate 8, thereby facilitating the movement of the impeller; wherein, the first cross bar 4, the connecting plate 1 and the second cross bar 6 are assembled to form a U shape, which is convenient for the installation of the impeller and can deliver the impeller into place, further facilitating the installation of the impeller and improving the work efficiency of the impeller installation.

[0020] In the present invention, a circular hole is provided on one end face of the convex block 2, and the fixing member 3 includes a fixing rod 301 arranged in the circular hole, a T-shaped cavity 303 provided in the fixing rod 301, and a vertical plate 304 arranged in the middle of the T-shaped cavity 303. An extrusion rod 306 is symmetrically slidably provided at one end of the T-shaped cavity 303, and the extrusion rod 306 movably passes through the fixing rod 301, and a movable plate 302 is provided in the extrusion rod 306, and an insertion rod 305 is provided on the side of the movable plate 302. A fixing hole is provided on the inner wall of the circular hole to cooperate with the insertion rod 305, and the insertion rod 305 movably passes through the T-shaped cavity 303 and extends into the fixing hole. A plurality of reset springs 307 are evenly provided between the movable plate 302 and the vertical plate 304. By using the reset spring 307, it is convenient to squeeze the movable plate 302, thereby facilitating the automatic reset of the insertion rod 305.

[0021] In the present invention, the outer wall of one end of the extrusion rod 306 is wrapped with a flexible rubber material to improve the flexibility of the extrusion rod 306 and avoid cutting hands when using the extrusion rod 306, thereby improving the comfort of using the extrusion rod 306.

[0022] In the utility model, a plurality of mounting holes 5 are evenly provided on the cross bar 4, so as to facilitate the connection of the cross bar 4 to the crane, thereby facilitating the lifting of the impeller.

[0023] Working principle: When the utility model is used, when lifting the impeller, the impeller is first installed on the impeller connecting plate 8, and then the cross bar 1 4 is connected to the hoist through a link, and the impeller is driven to move by the hoist to lift the impeller to a suitable position, wherein a U shape is formed between the cross bar 1 4, the connecting plate 1 and the cross bar 2 6, so that the cross bar 2 6 can be easily extended into the impeller installation cavity, thereby facilitating the impeller to be lifted to a suitable position;

[0024] Among them, after the impeller is hoisted, in order to facilitate the transportation of the tool, the tool needs to be disassembled, specifically: press the two extrusion rods 306, and the movement of the extrusion rods 306 drives the movable plate 302 to move, thereby driving the insertion rod 305 to move, so that the insertion rod 305 moves into the T-shaped cavity 303, and then the fixing rod 301 is released to release the fixation between the cross bar 1 4, the cross bar 2 6 and the connecting plate 1, so that the cross bar 1 4, the cross bar 2 6 and the connecting plate 1 exist independently, so as to facilitate the transportation of the tool; when installing the tool, the convex blocks 2 at the ends of the cross bar 1 4 and the cross bar 2 6 are respectively inserted into the two ends of the connecting plate 1, and then the fixing parts 3 are respectively inserted into the circular holes of the convex blocks 2, and then the fixing parts 3 are loosened, and under the action of the reset spring 307, the insertion rod 305 is inserted into the fixing hole to realize the assembly of the tool.

[0025] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
