[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1-4 This utility model provides a circuit breaker operating wrench that solves the problems of inconvenient operation and electric shock hazards associated with traditional circuit breaker operating handles in confined spaces. Through optimized structural design, it achieves convenient operation and safety protection in confined spaces. Details are as follows:

[0032] I. Overall structure and design of individual components;

[0033] 1. Wrench Body: The wrench body is made of 45# steel, which has sufficient strength and rigidity to meet the force required to apply to the circuit breaker handle during operation, ensuring that the wrench is not easily deformed or damaged during long-term use. The wrench body is integrally molded into a lever structure with a handle head 1, a bending part, and a gripping part 3. The gripping part 3 is in the form of a handle, and the size and shape of the handle are adapted to the human hand gripping habits, improving the comfort during operation.

[0034] The bent portion of the wrench is bent at 150° relative to the gripping portion 3. This specific angle design allows the gripping portion to be pushed and pulled along the normal direction of the locating pin 4, making it easy to move the circuit breaker handle 5. This structural design effectively extends the operating lever arm, allowing the operator to easily move the circuit breaker handle from a distance without having to get close to the circuit breaker. It is especially suitable for confined spaces, avoiding the problem of operators being unable to apply force due to space constraints.

[0035] 2. Wrench Sheet Metal Kit 6: The wrench sheet metal kit 6 is used for fixed connection with the molded case circuit breaker. As a key positioning component for wrench operation, the wrench sheet metal kit 6 is equipped with a press-fit positioning pin 4. The positioning pin 4 serves two purposes: firstly, it provides rotational positioning for the wrench, ensuring that the wrench moves along a preset trajectory during operation; secondly, the positioning pin 4 acts as a fulcrum for the wrench, using the lever principle to allow the operator to lift or press down the molded case circuit breaker handle 5 with less effort, reducing operational intensity.

[0036] 3. Positioning Hole 2 Design: The position of the positioning hole 2 of the wrench is determined through dynamic simulation and optimization using 3D software. During the simulation, the matching accuracy between the wrench and the positioning pin 4, the movement trajectory and operating stroke of the circuit breaker handle 5 are fully considered to ensure that during operation, the wrench head 1 can accurately align with and lift or press down the circuit breaker handle 5, ensuring the stability and reliability of each operation and avoiding operational failure or handle damage due to inaccurate positioning.

[0037] 4. Insulation Design: The faceplate is covered with an insulating sleeve made of high-quality insulating material. This sleeve not only has excellent electrical insulation properties, effectively blocking current conduction and preventing electric shock accidents caused by accidental contact with live parts during operation, but also has excellent wear resistance, able to withstand long-term gripping and environmental friction, ensuring that the insulating sleeve is not easily damaged during long-term use and maintains a stable insulation effect.

[0038] II. Material selection and manufacturing process;

[0039] 1. The materials to be selected are as follows:

[0040] Wrench body: Made of 45# steel, balancing strength and cost while meeting structural strength requirements; the surface is galvanized for rust prevention, improving the wrench's corrosion resistance and extending its service life.

[0041] Insulating sleeve: Select materials with good insulation properties (such as high-strength insulating rubber or heat-shrinkable insulating materials) to ensure that its insulation resistance meets relevant safety standards, while also having a certain degree of elasticity and wear resistance to meet the grip covering requirements.

[0042] 2. The manufacturing process is as follows:

[0043] The wrench body is processed using laser cutting technology. Laser cutting has high precision, which can ensure the dimensional tolerance of each part of the wrench, ensure the fitting accuracy of the positioning hole 2 and the positioning pin 4, and the accuracy of the bending angle.

[0044] All edges of the wrench body are chamfered to remove burrs generated during processing, preventing operators from being cut when holding or operating the wrench and improving product safety.

[0045] The insulating sleeve is wrapped around the surface of the grip part 3 of the wrench using a heat-shrink tubing process. After heat shrinking, the insulating sleeve fits tightly with the grip part 3 without loosening or wrinkling, ensuring the stability of the operator's grip while ensuring that the insulation performance of the insulating sleeve is not affected.

[0046] III. When using the wrench described in this utility model to operate the circuit breaker, the steps are as follows:

[0047] First, take the wrench sheet metal kit 6 ( Figure 2) and molded case circuit breakers ( Figure 3 ) Secure the connection to ensure that the wrench sheet metal kit 6 is installed firmly and the positioning pin 4 is in the correct position;

[0048] The operator holds a wrench ( Figure 1 The holding part 3 of the wrench inserts the positioning hole 2 of the wrench into the positioning pin 4 on the wrench sheet metal kit 6, so that the wrench and the wrench sheet metal kit 6 form a stable rotational connection.

[0049] Depending on the circuit breaker's opening and closing requirements, the operator pushes the lever holding part 3 clockwise or counterclockwise.

[0050] When it is necessary to close the circuit, push the holding part to make the wrench head 1 lift the molded case circuit breaker handle 5 to complete the closing action.

[0051] When it is necessary to open the circuit breaker, push the holding part to make the wrench head 1 press down on the molded case circuit breaker handle 5 to complete the opening action.

[0052] Through the above operations, with the help of the fulcrum of the positioning pin 4 and the lever arm design of the 150° bend, the operator can easily complete the operation from a position away from the circuit breaker without having to go into a confined space.

[0053] In summary, this utility model, through the design of the 150° bending part and the holding part 3, combined with the fulcrum effect of the positioning pin 4, extends the operating lever arm. Operators can move the circuit breaker handle from a distance by pushing and pulling the holding part, without having to adjust their operating posture in a confined space, thus greatly improving operating efficiency. At the same time, the precise design of the positioning hole 2 ensures the stability of operation and avoids operational delays caused by positioning deviations, making it particularly suitable for opening and closing operations in emergency situations.

[0054] In addition, the insulating sleeve covering the circuit breaker has good insulation performance, effectively blocking the current conduction between the operator and the live parts, thus physically preventing electric shock accidents. Furthermore, the remote operation design reduces the chance of the operator coming into contact with the live parts of the circuit breaker, further reducing safety hazards and ensuring the personal safety of the operator.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
