Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0031] Depend on Figure 1 As shown, it is a structural schematic diagram of a single-body multifunctional operating tool in this embodiment, including a middle-end connecting rod 1, a wrench body 2 and an extension cover plate 3, wherein the top of the middle-end connecting rod 1 is provided with a wrench body 2 for tightening bolts, and the end of the middle-end connecting rod 1 is provided with an extension cover plate 3 on the side away from the wrench body 2, and the inside of the middle-end connecting rod 1 is provided with a mounting mechanism 4 for assisting the extension cover plate 3 in mounting and disassembling.

[0032] During use, the distance between the two groups of wrenches at the end of the wrench can be flexibly adjusted through the use of the wrench body 2, so that the wrench body 2 can be docked with nuts of different specifications, and the middle-end connecting rod 1 is pressed, and the docking nut is rotated using the lever principle to achieve the purpose of disassembling the component. The operation of the expansion cover 3 itself can be docked with different fixings, which expands the scope of application of the equipment itself and ensures the working quality of the equipment itself.

[0033] Depend on Figure 3 As shown, it is a structural schematic diagram of the installation mechanism 4 in this embodiment, the installation mechanism 4 includes a docking plate 41, a docking groove 42 and a docking assembly 43, the docking plate 41 is fixedly installed on the side of the extension cover 3, and a docking groove 42 for sliding with the docking plate 41 is opened inside the middle-end connecting rod 1, and the docking assembly 43 is installed inside the middle-end connecting rod 1.

[0034] During use, by using the docking component 43 and releasing the clamping connection of the docking component 43 with the docking plate 41, the expansion cover 3 can be directly removed from the end of the middle connecting rod 1, and then the structure of the expansion cover 3 itself and the various components in the expansion cover 3 are used to disassemble and assemble different reinforcement parts, thereby improving the scope of application of the equipment itself and ensuring the working quality of the equipment itself.

[0035] By the attached Figure 4As shown, it is a structural schematic diagram of the docking component 43 in this embodiment, the docking component 43 includes a docking block 431, a pushing top plate 432 and a spring group 433. A movable groove is opened inside the middle-end connecting rod 1, and the movable groove is connected to the docking groove 42. The docking block 431 is slidably installed in the movable groove. The docking block 431 is engaged with the docking plate 41, and the pushing top plate 432 is fixedly installed on the upper surface of the docking block 431. The spring group 433 is arranged at the end of the docking block 431.

[0036] During use, the top plate 432 is pushed, and the docking block 431 slides into the movable groove under the drive of the top plate 432. At this time, the docking block 431 and the docking plate 41 are released from the clamping, and the spring group 433 is in a force storage state. Subsequently, the extension cover 3 can be removed from the end of the middle connecting rod 1, and the structure of the extension cover 3 itself can be used to disassemble different reinforcement parts. When the top plate 432 is released, the spring group 433 will release its accumulated elastic force and push the docking block 431 to the side close to the docking plate 41, so as to facilitate the subsequent installation of the extension cover 3.

[0037] By the attached Figure 4 As shown, the docking block 431 is composed of a limiting plate and a trapezoidal plate. The limiting plate is slidably installed inside the movable groove. A matching locking groove is provided at the connection between the movable groove and the docking groove 42. The trapezoidal plate is fixedly installed on the side of the limiting plate, and the trapezoidal plate is slidably connected to the locking groove.

[0038] The installation of the limit plate during use limits the overall movement range of the docking block 431 to prevent the docking block 431 from being directly ejected from the moving groove under the elastic force of the spring group 433. The establishment of the trapezoidal plate allows the docking block 431 to automatically slide into the moving groove when the docking plate 41 enters the docking groove 42, thereby facilitating the overall installation of the expansion cover 3.

[0039] By the attached Figure 4 As shown, the docking plate 41 is rectangular in shape as a whole, and inclined portions are provided on both sides of the docking plate 41.

[0040] During use, the installation of the inclined parts on both sides of the docking plate 41 facilitates the cooperation between the docking plate 41 and the trapezoidal plate in the docking block 431, thereby squeezing the position of the docking block 431. The shape of the docking plate 41 itself is limited so that the docking plate 41 itself can act as a flat-blade screwdriver to disassemble and assemble specific nuts and fixings, so that the docking plate 41 itself can be fully utilized.

[0041] By the attached Figure 5As shown, it is a structural schematic diagram of the expansion cover 3 in this embodiment, the expansion cover 3 includes a disassembly top cover 31, a hexagonal rotating column 32 and a placement bottom groove 33, the disassembly top cover 31 is arranged at the end of the middle-end connecting rod 1, the hexagonal rotating column 32 is fixedly installed on the lower surface of the disassembly top cover 31, and the hexagonal rotating column 32 is provided with a plurality of groups, and each group of hexagonal rotating columns 32 has different specifications, and the middle-end connecting rod 1 is provided with a placement bottom groove 33 for plugging in with the hexagonal rotating column 32.

[0042] During use, a limit block is installed at the end of the disassembled top cover 31, and a limit groove is opened inside the middle end connecting rod 1 to dock with the limit block, so as to assist in the quick installation of the disassembled top cover 31. The installation of multiple groups of hexagonal rotating columns 32 at the bottom end of the disassembled top cover 31 allows the hexagonal rotating columns 32 to be disassembled and assembled according to hexagon socket bolts and fixings of different specifications, so as to assist the operation and use of the device as a whole.

[0043] By the attached Figure 5 As shown, the expansion cover 3 further includes a hexagonal rotation groove 34 , and the disassembly top cover 31 is provided with a hexagonal rotation groove 34 , and there are a total of multiple groups of hexagonal rotation grooves 34 , and each group of hexagonal rotation grooves 34 has a different size.

[0044] During use, the hexagonal rotating groove 34 is set so that when the wrench as a whole is rotated for hexagonal nuts or fixings of certain sizes, the hexagonal rotating groove 34 can directly fit on the outside of the nut or fixing, and the nut or fixing can be disassembled and assembled without adjusting the position of the components inside the wrench body 2, thereby saving operation time and improving overall work efficiency.

[0046] During use, the expansion cover 3 is disassembled from the end of the middle connecting rod 1. At this time, the storage slot 51 is completely exposed, and the cross disassembly head 52 stored in the storage slot 51 can be taken out, and the cross disassembly head 52 can be inserted into the installation socket 53. By utilizing the operation of the cross disassembly head 52, the cross nuts and fixings can be quickly disassembled and assembled, further expanding the scope of use of the equipment itself.

[0047] By the attached Figure 6As shown, the cross disassembly head 52 is composed of a bottom connecting block and a cross rotating member, and the bottom connecting block is fixedly connected to the cross rotating member. During use, the cross disassembly head 52 can accurately and stably disassemble and assemble the cross nuts and fixings, and multiple groups of cross disassembly heads 52 of different sizes can be placed inside the storage slot 51, making the practical effect of the equipment itself more efficient.

[0048] By the attached Figure 6 As shown, the bottom connecting block is made of a magnet with magnetic properties, and the inside of the mounting socket 53 is filled with a magnetic block that is attracted to the bottom connecting block. During use, the magnet of the bottom connecting block is installed to facilitate the docking of the mounting socket 53 and the cross disassembly head 52, thereby speeding up the docking between the components.

[0049] By the attached Figure 1 As shown, a circular hanging groove is provided inside the middle connecting rod 1.
