[0027] The main rod 1 has a cylindrical tubular structure and serves as the installation base for the F wrench. A pry head 6 is provided at one end of the main rod 1, through which the protective cover of a 200L standard lubricating oil barrel can be opened. A connecting ring 7 is installed at the other end of the main rod 1 to facilitate the combined use of two F wrenches. A first main wrench 2 is welded to the end of the main rod 1 near the pry head 6. The first main wrench 2 has a cylindrical structure. The axis of the first main wrench 2 is parallel to the axis of the connecting ring 7, and the outer diameter of the first main wrench 2 is smaller than the inner diameter of the connecting ring 7 to facilitate the insertion of the first main wrench 2 on another F wrench into the connecting ring 7 to achieve the combined use of two F wrenches. A second main wrench 3 with the same cylindrical structure is welded to the left side of the first main wrench 2. The second main wrench 3 is parallel to the first main wrench 2. The second main wrench 3 cooperates with the first main board to achieve the opening and closing of the large handwheel valve. A first sub-wrench 4 is welded to the main rod 1 on the opposite side of the first main board. The first sub-wrench 4 is also a cylindrical structure, and the first sub-wrench 4 is 180° away from the first main wrench 2, that is, the first sub-wrench 4 is coaxial with the first main wrench 2, so as to realize the opening and closing of the small handwheel valve 9. A second sub-wrench 5 is vertically welded on the left side of the first sub-wrench 4. The second sub-wrench 5 is a rectangular structure, so as to facilitate opening the small lid 10 of the 200L standard lubricating oil barrel, and the second sub-wrench 5 is parallel to the first sub-wrench 4, so that the second sub-wrench 5 cooperates with the first sub-wrench 4 to open the large lid 8 of the 200L standard lubricating oil barrel, so as to achieve full coverage of the opening and closing operations of various manual valves of different structural sizes commonly used on site and 200L standard lubricating oil barrels or solvent barrels, that is, the multifunctional application of the F wrench, thereby avoiding the frequent replacement of tools by staff, improving work efficiency, reducing the space occupied by tools, and avoiding the production of multiple F wrenches of different specifications, reducing the occurrence of random placement and discarding of tools.
[0028] Furthermore, the pry head 6 has a 45° bevel angle.
[0029] The pry head 6 in this embodiment is beveled at a 45° angle to facilitate better prying of the lubricating oil barrel protective cover.
[0030] Furthermore, an anti-slip lining is provided inside the connecting ring 7 .
[0031] In this embodiment, an anti-slip lining (not shown) is installed in the connecting ring 7 to increase the friction between the connecting ring 7 and the second main wrench 3 to prevent the second main wrench 3 from slipping out of the connecting ring 7 during use.
[0032] Furthermore, the surfaces of the first main wrench 2 , the second main wrench 3 , the first auxiliary wrench 4 and the second auxiliary wrench 5 are all provided with anti-slip patterns.
[0033] In this embodiment, anti-slip patterns (not shown in the figure) are provided on the surfaces of the first main wrench 2, the second main wrench 3, the first sub-wrench 4, and the second sub-wrench 5 to increase the frictional force of contact between the first main wrench 2, the second main wrench 3, the first sub-wrench 4, and the second sub-wrench 5 when in use, thereby facilitating the use of the F wrench.
[0034] Furthermore, the main rod 1 has a cylindrical structure, and the outer surface of the main rod 1 is provided with anti-slip lines.
[0035] The main rod 1 in this embodiment adopts a cylindrical structure so that the staff can directly hold the main rod 1 with their hands. In addition, this embodiment also provides anti-slip grooves on the outer surface of the main rod 1 (not shown in the figure) to facilitate the use of the F wrench and prevent the staff from losing their hands during use.
[0036] Furthermore, the first main wrench 2 , the second main wrench 3 , the first auxiliary wrench 4 and the second auxiliary wrench 5 are all made of copper.
[0037] In this embodiment, the first main wrench 2, the second main wrench 3, the first sub-wrench 4 and the second sub-wrench 5 are all made of copper to avoid sparks generated by friction during use, thereby meeting the use requirements of explosion-proof areas.
[0038] When the large handwheel valve needs to be opened or closed, the first main wrench 2 is inserted into the inner side of the large handwheel valve, so that the second main wrench 3 is stuck on the outer side of the large handwheel valve. The staff only needs to manually move the main rod 1 to realize the opening and closing operation of the large handwheel valve.
[0039] When the small handwheel valve 9 needs to be opened or closed, the first pair of wrenches 4 is inserted into the inner side of the small handwheel valve 9, so that the second pair of wrenches 5 are stuck on the outer side of the small handwheel valve 9. The staff only needs to manually move the main rod 1 to realize the opening and closing operation of the small handwheel valve 9.
[0040] When a larger valve needs to be opened or closed, the first main wrench 2 of the first F wrench is first inserted into the inner side of the valve, so that the second main wrench 3 is stuck on the outer side of the valve. Then, the first main wrench 2 of the second F wrench is inserted into the connecting ring 7 at the tail of the first F wrench to increase the torque. Finally, by moving the main rod 1 of the second F wrench, the larger valve can be opened or closed.
[0041] When it is necessary to open the protective cover of a 200L standard lubricating oil barrel, the staff only needs to insert the pry head 6 on the top of the main rod 1 into the bottom of the protective cover and pry it gently to open the protective cover of the lubricating oil barrel; after completion, the second deputy shift's hand plate is then inserted into the small cover 10 of the lubricating oil barrel under the protective cover, so that the second deputy shift's hand plate is stuck in the groove in the middle of the small cover 10 of the lubricating oil barrel. At this time, only the main rod 1 needs to be slightly rotated to open the small cover 10 of the 200L standard lubricating oil barrel;
[0042] If it is necessary to open the large lid 8 of a 200L standard lubricating oil barrel, the staff only needs to insert the first pair of wrenches 4 and the second pair of wrenches 5 into the inner side of the large lid 8 of the oil barrel, so that the first pair of wrenches 4 and the second pair of wrenches 5 are both stuck on the blocking block on the inner side of the large lid 8 of the oil barrel. At this time, only the main rod 1 needs to be slightly rotated to open the large lid 8 of the 200L standard lubricating oil barrel, realizing the multi-functional application of the F wrench, avoiding the staff from frequently changing tools and improving work efficiency.
