[0002] A wrench is a common tool for installation and removal. It is a hand tool that uses leverage to tighten or loosen bolts, screws, nuts, and other threaded fasteners, including those with open or recessed holes. Wrenches are typically made of structural steel, either carbon or alloy.

[0003] Traditional manual wrenches, also known as ordinary wrenches, are mainly used in everyday life and work, and are relatively simple to use. Manual wrenches are mainly divided into single-ended open-end wrenches, double-ended open-end wrenches, adjustable wrenches, box wrenches, Allen wrenches, T-wrenches, L-wrenches, and other types of wrenches.

[0004] Traditional wrenches have a narrow range of applications and are not universally applicable. Although there are existing technologies, such as the adjustable wrench designed by the Chinese invention patent with publication number CN115609517A, which can improve the scope of application to a certain extent, petrochemical companies involve a wide variety of valves and screws, and the abnormal situations on site are varied. For example, it is necessary to open and close small-diameter valves, open and close the doors of the field control cabinet, and tighten or loosen screws. Carrying a large number of wrenches for inspection will increase the burden on the inspection personnel, making it inconvenient for long-term inspections. In addition, due to the large number of categories and specifications, it is not easy to manage tools and equipment, and they are easy to lose.

[0005] Therefore, it is necessary to study a portable inspection tool to solve the above problems or mitigate their impact. Utility Model Content

[0030] The present invention will be further described below with reference to the accompanying drawings.

[0031] like Figure 1 and Figure 2 As shown, the portable inspection tool of this utility model may include a handle 1 and a first wrench 2 and a second wrench 3 both connected to the handle 1;

[0032] The handle 1 is a long strip structure; the first wrench 2 is close to one end of the handle 1 and connected to one side thereto. The first wrench 2 has a C-shaped structure and is used to tighten or loosen external screws or open or close valves; the second wrench 3 is connected to one end of the handle 1 and is used to tighten or loosen internal screws.

[0033] Specifically, handle 1 is designed as a long strip to facilitate one-handed grip and operation by inspection personnel. The first wrench 2, located near and connected to one side of handle 1, is C-shaped and can be fitted over the head of an external screw or secured to a valve handwheel for tightening or loosening the external screw or opening / closing the valve. The second wrench 3, connected to one end of handle 1, is used to tighten or loosen internal screws to open / close the control cabinet door.

[0034] Overall, the portable inspection tool, with its first wrench 2 and second wrench 3 design, can be used to tighten or loosen different types of screws on equipment, open or close valves in chemical plants, and operate control cabinet doors, achieving multiple uses in one tool. This reduces the inspection burden on personnel, simplifies tool management, saves time for personnel to retrieve tools, improves the convenience of personnel operations, and enables the opening and closing of small-diameter valves and control cabinet doors in chemical plants, thereby improving the efficiency of scheduled inspections and checking the operation of control cabinets.

[0035] In one example, the inner side of the first wrench 2 has a plurality of clamping surfaces 21 connected in sequence, which cooperate to form a groove that matches the head of the hexagonal screw. Specifically, the inner side of the first wrench 2 can have grooves with different structures depending on the type of hexagonal screw it is used with. For example, for hexagonal screws, adjacent clamping surfaces 21 form a 120° angle, and the size of the groove formed by the cooperation of the plurality of clamping surfaces 21 matches the size of the hexagonal screw.

[0036] Furthermore, the clamping surface 21 has a ridge-like convex surface, and the slot is a Torx slot. In this way, the first wrench 2 can be used to tighten and loosen various Torx screws, and can also be used for other external angle screws with matching dimensions, thus broadening its applicability.

[0037] In one example, the first wrench 2 includes a first clamping arm 22 and a second clamping arm 23 that are positioned opposite each other. Both the first clamping arm 22 and the second clamping arm 23 are arc-shaped structures, and the two cooperate to form a clamping space for clamping the outer corner screw.

[0038] The first clamping arm 22 is provided with a clamping member 24, which is used to clamp the outer corner screw, which is smaller than the clamping space, against the second clamping arm 23.

[0039] Specifically, a first clamping arm 22 and a second clamping arm 23, both with an arc-shaped structure, are positioned opposite each other. One end of each clamping arm 22 and the corresponding end of the second clamping arm 23 are fixedly connected to and fixed to the handle 1. The other ends of the two arms are spaced apart, forming a clamping space, or slot, between them for clamping external corner screws, thus forming a C-shaped first wrench 2. The first wrench 2 can then be used to clamp external corner screws whose size matches the clamping space. To further improve the applicability of the first wrench 2, a clamping member 24 is provided on the first clamping arm 22. By adjusting the clamping member 24 towards the second clamping arm 23, external corner screws smaller than the clamping space can be clamped against the second clamping arm 23, thereby loosening or tightening external corner screws smaller than the clamping space. The first clamping arm 22 and the second clamping arm 23 can be an integral structure.

[0040] Furthermore, the first clamping arm 22 is provided with a through threaded hole 25, and the clamping member 24 is a screw. The clamping member 24 can be threadedly engaged with the threaded hole 25 to adjust the feed depth in the direction of the second clamping arm 23. In this way, the first wrench 2 can adjust the feed depth in the direction of the second clamping arm 23 by rotating the clamping member 24, thereby enabling the clamping of external angle screws of different sizes. Preferably, the diameter of the threaded hole 25 can be 6mm, and its internal thread can be designed as an M6×30mm thread, that is, the clamping member 24 is an M6×30mm threaded rod.

[0041] Furthermore, a knob 26 is connected to the end of the clamping member 24 away from the second clamping arm 23. The knob 26 is used to manually adjust the feed depth of the clamping member 24. By rotating the clamping member 24 by the knob 26, the feed depth of the clamping member 24 can be easily adjusted by the inspector, which is convenient and labor-saving, so as to achieve fast and accurate clamping.

[0042] In one example, the first wrench 2 has an opening 27 on the side away from the handle 1, which is used to lock onto the valve handwheel to open or close the valve.

[0043] Furthermore, the width of the opening 27 gradually decreases along the direction away from the handle 1. Specifically, the spaced ends of the first clamping arm 22 and the second clamping arm 23 are both wedge-shaped cut surfaces to form a trapezoidal opening 27 from a side view, which can better fix the valve handwheel and make it less prone to slippage. The width of the distal end of the opening 27 away from the handle 1 can be 12-20 mm.

[0044] In one example, the second wrench 3 can be an Allen wrench, with a length of 1 / 5 to 1 / 3 of the handle 1. This length design avoids the inconvenience caused by excessively long tools and facilitates the application of force. The length of the second wrench 3 can be 15 to 45 mm to facilitate the opening and closing of the cabinet door of the field control cabinet for inspection by the inspection personnel.

[0045] In one example, the end of handle 1 furthest from the second wrench 3 has an anti-slip design, such as adding anti-slip protrusions or textured surfaces, to prevent slippage during use and facilitate operation. To enhance grip stability and comfort, the surface of handle 1 can also be covered with an anti-slip material, such as rubber or silicone, and handle 1 can be designed in an ergonomic shape and size. Furthermore, handle 1 can be designed as a cuboid.

[0046] In one example, the end of the handle 1 furthest from the second wrench 3 may have a through-hole 11 for storing the tool. The diameter of the hanging hole 11 may be 8–15 mm.

[0047] It should be noted that the portable inspection tool of this utility model is highly practical, simple to manufacture, and inexpensive, and can be made directly by modifying existing wrenches. For example, the ring-shaped wrench head of a box wrench can be cut off and used as the first wrench 2, which is welded to the left side of the handle 1. A wedge-shaped cut is made on the ring-shaped wrench head to form an opening 27, through which the opening of small-diameter valves can be adjusted. Then, by adding a movable bolt as a clamping part 24 to the ring-shaped wrench head, the distance between the bolt and the inner ring of the ring-shaped wrench head can be adjusted to achieve the purpose of flexibly disassembling and installing various external screws. Finally, a small section of an internal hex wrench is welded to the upper end of the handle 1 near the ring-shaped wrench head as the second wrench 3, so as to realize the cabinet door of the portable switch control cabinet.

[0048] In summary, the beneficial effects of this utility model compared with the prior art include at least the following:

[0049] This portable inspection tool can further optimize the inspection workload of inspection personnel, simplify tool management, and has low manufacturing cost and wide application range. Standard-sized small F-wrenches, due to their width, are prone to slippage when opening and closing small-diameter valves. The wedge-shaped opening of the first wrench improves the efficiency of opening and closing small-diameter valves. The inspection tool can be applied to different scenarios by rationally combining frequently used wrenches, improving the speed at which operators can handle abnormal situations discovered during inspections and further optimizing the abnormal situation handling process.

[0050] This portable inspection tool integrates multiple functions into a single tool, which not only improves inspection efficiency but also reduces the burden on inspection personnel. Its unique design allows inspection personnel to easily handle various maintenance tasks, making it an ideal tool for industrial production and equipment maintenance.

[0051] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
