Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The purpose of the utility model is to provide an auxiliary tool for opening the iron cover of an oil drum, so as to solve the problems existing in the above-mentioned prior art. The utility model has a simple structure, is easy to use, and effectively improves the working efficiency.

[0024] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] The utility model provides an auxiliary tool for opening the iron cover of an oil drum, such as Figures 1 to 3As shown, it includes: a pry bar mechanism, a fixing assembly and a long arm 1. The pry bar mechanism includes a pry bar arm 2 and two tilting blocks 201. The two tilting blocks 201 are respectively connected to both sides of the bottom of the pry bar arm 2. One tilting block 201 is used to extend under the edge of the oil barrel iron cover, and the position where the pry bar arm 2 contacts the oil barrel iron cover is used as a fulcrum. The pry bar mechanism can be rotated to open the oil barrel iron cover; one end of the long arm 1 is provided with a gripping portion, and the other end of the long arm 1 is used to connect with the top of the pry bar arm 2 through the fixing assembly. The part can be detachably fixedly connected, and the pry arm 2 can slide in the length direction of the long arm rod 1 and maintain the position after sliding, and the length between the gripping part and the connection position of the pry arm 2 and the long arm rod 1 can enable the operator to stand and drive the pry mechanism through the gripping part to lift the oil drum metal cover. By setting the pry mechanism and the long arm rod 1, the head block 201 at the bottom of the pry arm 2 is extended under the edge of the oil drum metal cover, and the contact position between the pry arm 2 and the oil drum cover is used as a fulcrum to easily lift the oil drum cover. The gripping part at one end of the long arm rod 1 makes it convenient for the operator to stand and operate, reduces labor intensity, and improves operating efficiency. The detachable connection and sliding design of the pry arm 2 and the long arm rod 1 make it easy to adjust the position according to actual conditions, which increases the flexibility and applicability of the tool.

[0026] In a preferred embodiment, a slot 202 is provided at the top of the pry arm 2. The long arm 1 is slidably connected to the slot 202 and can be fixed to the pry arm 2 in the slid position by a fixing assembly. The provision of the slot 202 makes the connection between the long arm 1 and the pry arm 2 more stable. The sliding connection facilitates adjustment of the relative position of the two to meet different operational requirements. The fixing assembly fixes the slid position, ensuring the stability of the tool during operation and improving its reliability.

[0027] In a preferred embodiment, the fixing assembly includes a first threaded tube 203, a second threaded tube 203, a first bolt rod 204, and a second bolt rod 204. A first through hole and a second through hole are respectively provided on either side of the slot 202. The first threaded tube 203 and the second threaded tube 203 are respectively fixedly connected to either side of the top of the pry arm 2, with the first threaded tube 203 communicating with the first through hole, and the second threaded tube 203 communicating with the second through hole. The first bolt rod is threadedly connected to the first threaded tube 203, passes through the first through hole, and then extends into the slot 202, tightening one side of the long arm 1. The second bolt rod is threadedly connected to the second threaded tube 203, passes through the second through hole, and then extends into the slot 202, tightening the other side of the long arm 1. With this fixing assembly design, the long arm 1 can be fixed by rotating the bolt rod 204, which is simple and convenient to operate. The design of the double threaded tube 203 and the bolt rod 204 increases the stability of the fixation, ensuring that the pry arm 2 and the long arm 1 do not slide relative to each other during use, thereby improving the safety and reliability of the tool.

[0028] In a preferred embodiment, a guide groove 205 is provided on one side of the top of the slot 202. The guide groove 205 is tilted to increase the opening of the slot 202. The tilted guide groove 205 increases the opening of the slot 202, making it easier for the long arm rod 1 to slide into the slot 202, thereby facilitating the assembly and adjustment of the tool and improving work efficiency.

[0029] In a preferred embodiment, the auxiliary tool for opening the iron cover of the oil drum also includes a hand guard rod 3, which is fixedly connected to the grip portion so that the back of the operator's hand is located between the grip portion and the hand guard rod 3. Adding the hand guard rod 3 can protect the operator's hand during operation, prevent the hand from being hit or compressed, and improve the safety of the operation.

[0030] In a preferred embodiment, the hand guard 3 is L-shaped and made of a rubber rod. The L-shaped hand guard 3 is more ergonomic and can better protect the hand. The rubber rod has a certain elasticity and can absorb some of the pressure during operation, improving the comfort of operation.

[0031] In a preferred embodiment, the auxiliary tool for opening the metal lid of an oil drum further includes a protective soft cover 102, which is detachably fixed to the handle. The protective cover 102 increases friction on the handle, preventing hand slippage during operation and improving operational stability. The detachable design facilitates replacement and cleaning of the protective cover 102, keeping the tool clean and in good condition.

[0032] In a preferred embodiment, the grip portion is provided with an annular mounting groove, to which the protective soft cover 102 is detachably fixed. The annular mounting groove provides a stable mounting position for the protective soft cover 102, ensuring that the protective soft cover 102 does not shift during use. The detachable connection makes the installation and removal of the protective soft cover 102 more convenient and quick.

[0033] The working principle of the auxiliary tool for opening the metal lid of an oil drum provided by this utility model is as follows: The long arm lever 1 introduced in the design of the new oil drum lid opening tool is a key feature, which embodies the application of the lever principle. The lever principle is a fundamental concept in physics that involves using levers to amplify the effect of force. In this tool, the design of the long arm lever 1 allows the operator to apply a small force at one end of the lever, which is amplified by the lever's pivot point (fulcrum) to generate a larger force at the other end, thus easily prying the oil drum lid open.

[0034] Pivot Point Location: The fulcrum of a tool is typically located near the tool head, where it contacts the oil drum cap. This design maximizes force output from the handle end. When the operator applies downward force at the distal end of the boom 1, the head near the fulcrum transfers this force to the oil drum cap with greater pressure.

[0035] Force Distribution and Efficiency: Due to the long boom 1, the operator can generate high torque without exerting significant force. Torque is the product of force and the lever arm (the distance from the fulcrum to the point of force application). The use of the long boom 1 significantly increases the lever arm length, thereby increasing torque. This means that even a relatively small force can effectively pry open a tightly secured oil drum lid.

[0036] Safety and Ergonomics: Ergonomics and safety were also considered in the design. The long boom allows the operator to use the tool without bending over, which not only improves work efficiency but also significantly reduces the risk of back and waist injuries. Furthermore, the handle is designed for grip comfort and anti-slip properties, ensuring tool stability during operation and preventing accidents caused by slippage.

[0037] Through the above design and working principle, this new oil drum lid opening tool not only improves operational efficiency, but also greatly improves operational safety and comfort.

[0038] The combination of the long arm 1 and the pry arm 2 significantly reduces the force required to open the oil drum lid. The long arm 1 design allows the user to operate while standing, reducing the need to bend over frequently, thereby improving operating efficiency and reducing labor intensity.

[0039] Increased operational safety: The tail of the long arm 1 is equipped with an annular groove 101 and an embedded protective soft cover 102, which enhances friction at the grip and prevents hand slippage. In addition, the L-shaped hand guard 3 provides bottom protection, preventing the hand from being hit or pressed during operation, thus increasing user safety.

[0040] Improved user comfort: The protective soft cover 102 not only increases grip friction but also provides a more comfortable grip through its material, reducing hand fatigue that can occur during prolonged operation. Furthermore, the elastic rubber rod (hand guard 3) can absorb some of the pressure during operation, further enhancing comfort.

[0041] Easy Adjustment and Maintenance: The pry lever mechanism is connected to the long arm 1 via a sliding slot 202, allowing the position of the pry lever arm 2 to be easily adjusted as needed. The design of the fixing assembly ensures that once adjusted, the pry lever arm 2 is firmly fixed in the desired position. This design not only makes the tool more flexible, but also facilitates daily maintenance and possible component replacement.

[0042] Easy to carry and store: The design of the tool allows the pry arm 2 to be easily separated from the long arm 1, which allows the entire tool to be disassembled into smaller parts when not in use, making it easy to carry and store, suitable for on-site and mobile operations.
