Preferably, the adjusting portion 14 is disposed near the head of the handle 11.

[0036] The fixed plate lip 12 is fixedly arranged on the head of the handle 11, and the fixed plate lip 12 is arranged close to one side of the handle 11, and the clamping surface of the fixed plate lip 12 faces the central axis of the handle 11;

[0037] The movable plate lip 13 is provided with a first working surface 131 and a second working surface 132, which are respectively located on opposite sides of the movable plate lip 13. The movable plate lip 13 is detachably provided on the head of the handle 11, and is provided close to the side of the handle 11 away from the fixed plate lip 12. The movable plate lip 13 is provided with a mating thread that is transmission-connected to the adjustment portion 14; by rotating the adjustment portion 14, the movable plate lip 13 can be driven to move toward or away from the fixed plate lip 12;

[0038] When the movable plate lip 13 approaches the fixed plate lip 12, the movable plate lip 13 and the fixed plate lip 12 can clamp the parts between the movable plate lip 13 and the fixed plate lip 12, and then the handle 11 can be pulled to drive the parts to rotate, thereby realizing the removal / installation of the parts;

[0039] Of course, by adjusting the direction of the movable plate lip 13, the first working surface 131 or the second working surface 132 can be matched with the clamping surface of the fixed plate lip 12 to assemble and disassemble different parts;

[0040] There are two detachable cutter heads 2, which are respectively arranged on the fixed plate lip 12 and the movable plate lip 13. The axis of the detachable cutter heads 2 is perpendicular to the movable direction of the movable plate lip 13, and the disassembly ends of the two detachable cutter heads 2 extend from the same side of the adjustable wrench 1, so that the two detachable cutter heads 2 can be inserted into the two disassembly holes of the pressure plate of the angle grinder grinding wheel. Then, the handle 11 is pulled to realize the removal or installation of the pressure plate of the angle grinder grinding wheel. Of course, by rotating the adjustment part 14, the distance between the two detachable cutter heads 2 can be adjusted to adapt to the removal or installation of the pressure plates of angle grinder grinding wheels of different sizes.

[0041] The multifunctional disassembly and assembly tool combines a wrench, a pipe wrench and a grinding disc disassembly and assembly tool into one. In the daily maintenance of blast furnace hot blast stoves, the number of tools required to be carried by maintenance personnel can be reduced, thereby alleviating the maintenance burden of maintenance personnel.

[0042] In order to better understand the adjustment of the direction of the movable plate lip 13, this embodiment takes the initial state as the first working surface 131 and the clamping surface are matched (see Figure 1) is used as an example to illustrate that the direction of the movable plate lip 13 is adjusted by the following steps:

[0043] Rotate the adjusting portion 14 to move the movable plate lip 13 away from the fixed plate lip 12 and out of the head of the handle 11;

[0044] The maintenance personnel can adjust the direction of the movable plate lip 13 so that the second working surface 132 of the movable plate lip 13 faces the direction of the fixed plate lip 12, and then install the movable plate lip 13 on the head of the handle 11 and rotate the adjustment part 14 to move the movable plate lip 13 toward the fixed plate lip 12 (see Figure 3 );

[0045] At this point, maintenance personnel can use the multifunctional disassembly and assembly tool to disassemble and assemble the pipeline.

[0046] In some embodiments, the first working surface 131 cooperates with the clamping surface to enable installation and removal of nuts and bolts;

[0047] The second working surface 132 cooperates with the clamping surface to realize the installation and removal of the pipeline. In order to make the second working surface 132 and the clamping surface better clamp the pipeline, a plurality of bite teeth 1321 are provided on the second working surface 132. The plurality of bite teeth 1321 are arranged along the length direction of the second working surface 132. Figure 3 , to increase the roughness of the second working surface 132. This prevents relative rotation between the second working surface 132, the clamping surface, and the pipeline when the second working surface 132 and the clamping surface clamp the pipeline, thereby facilitating installation and removal of the pipeline. Preferably, the second working surface 132 is provided with an arcuate surface that is recessed toward the center of the movable plate lip 13. This arcuate surface increases the contact area between the second working surface 132 and the pipeline, further increasing the friction between the second working surface 132 and the pipeline, thereby making the multifunctional assembly and disassembly tool more convenient to use.

[0048] In some embodiments, the fixed plate lip 12 and the movable plate lip 13 are both provided with a step hole 15, and the two disassembly and assembly heads 2 are respectively provided in the step holes 15 on the fixed plate lip 12 and the movable plate lip 13. Figure 2 The tail end of the disassembly head 2 is provided with a limiting screw head 3 to prevent the disassembly head 2 from passing through the step hole 15, so that the structure of the multifunctional disassembly tool is more stable.

[0049] Preferably, the depth of the large hole of the above-mentioned step hole 15 is greater than the height of the limiting screw head 3, so that when the disassembly head 2 is installed in the step hole 15, the limiting screw head 3 is completely immersed in the step hole 15, so as to reduce the volume of the multifunctional disassembly tool and facilitate the use of the multifunctional disassembly tool in a small space.

[0050] It should be noted that the above-mentioned step hole 15 is composed of a large hole and a small hole, the large hole and the small hole are connected, and the large hole and the small hole are coaxially arranged, and the diameter of the large hole is larger than the diameter of the small hole; in this embodiment, the cross-sectional shape of the disassembly tool head 2 is circular, the diameter of the small hole matches the diameter of the cross-section of the disassembly tool head 2, and the diameter of the small hole is smaller than the size of the limiting screw head 3, so that the disassembly tool head 2 can pass through the small hole smoothly, and the limiting screw head 3 can only be stuck at the step connecting the large hole and the small hole.

[0051] In some embodiments, the multifunctional disassembly and assembly tool further includes a locking nut 4;

[0052] The side wall of the disassembly cutter head 2 is provided with an external thread matching the locking nut 4, see Figure 2 The disassembly end of the disassembly head 2 passes through the step hole 15 and is connected to the locking nut 4. The disassembly head 2 can be locked by the locking nut 4 to prevent the disassembly head 2 from falling off the fixed plate lip 12 or the movable plate lip 13, so that the structure of the multifunctional disassembly tool is more stable.

[0053] In some embodiments, a disassembly groove for facilitating the insertion of a disassembly tool is provided on the side of the limiting screw head 3 facing away from the disassembly tool head 2. The disassembly tool can easily twist the disassembly tool head 2, making the installation and removal of the disassembly tool head 2 more convenient. Preferably, the disassembly groove can be in the shape of a cross, a straight line, or a regular hexagon. The three shapes of disassembly grooves correspond to the cross-shaped screwdriver, the straight-shaped screwdriver, and the hexagonal wrench in the prior art, respectively.

[0054] In some embodiments, the cross-sectional shapes of the disassembly ends of the two disassembly blade heads 2 are respectively a "cross" shape and a "one" shape, see Figure 2 During use, the two disassembly and assembly heads 2 can be used to respectively disassemble / assemble screws with "cross" and "I" shaped nail caps, so that the use of the multifunctional disassembly and assembly tool is more convenient.

[0055] In some embodiments, two opposite side walls of the handle 11 are respectively provided with a first scale mark (not shown in the figure) and a second scale mark (not shown in the figure);

[0056] The marking values of the first scale mark increase from the tail of the handle 11 to the head of the handle 11;

[0057] The marking values of the second scale mark increase from the head of the handle 11 to the tail of the handle 11. The maintenance personnel can select the first scale mark or the second scale mark to measure the object to be measured according to needs and habits.

[0058] In some embodiments, anti-slip grooves are provided on the side walls of the handle 11 to increase the roughness of the handle 11 through the anti-slip grooves, thereby increasing the friction between the maintenance personnel's hands and the handle 11 during use, thereby making the multifunctional disassembly and assembly tool safer during use.
