AI Technical Summary
Existing remote-controlled bomb disposal equipment's wire cutter has poor cutting effect and requires frequent refilling of explosives. Furthermore, a single cutting head may cause the wire to slip, posing a safety hazard.
The movable blade, driven by a push rod motor, works in conjunction with a fixed blade. The movable blade is designed in the shape of a hook. The push rod motor moves the movable blade closer to or away from the fixed blade to form a closed cutting area, ensuring stable wire cutting. The guide groove improves the stability of movement and supports quick blade replacement.
It achieves reliable and stable wire cutting, avoids slippage, simplifies equipment preparation procedures, and improves operational safety and efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of remote control bomb disposal equipment technology, and in particular to a wire cutter for remote control bomb disposal equipment. Background Technology
[0002] In counter-terrorism operations, the specialized dismantling of various types of explosive devices is often required, which mainly involves the precise cutting of related wires. However, improper operation during the dismantling process, such as accidentally cutting the wrong wire, can lead to catastrophic consequences, causing significant casualties, incalculable economic losses to the country, and inflicting deep psychological trauma on the victims' families.
[0003] A search revealed a Chinese patent document disclosing a remotely controlled wire cutter for bomb disposal equipment [Application No.: 2021213157887; Publication No.: CN214842822U]. This wire cutter uses a propellant device to generate instantaneous explosive force to drive the internal cutting head. However, it requires refilling with propellant after use, and because it only has a single cutting head, its cutting effect may be unsatisfactory. Therefore, it is necessary to design a wire cutter for remotely controlled bomb disposal equipment. Summary of the Invention
[0004] The purpose of this application is to provide a wire cutter for remotely controlling bomb disposal equipment.
[0005] To achieve the above objectives, this application provides the following technical solution: a wire cutter for remote-controlled bomb disposal equipment, comprising a hollow base, characterized in that a fixed blade is installed at the front end of the base, a movable blade cooperating with the fixed blade is slidably installed at the front end of the base, a push rod motor is installed at the rear end of the base, the push rod motor is electrically connected to the control box of the remote-controlled bomb disposal equipment via a circuit, the push rod end of the push rod motor is connected to the movable blade, and under the action of the push rod motor, the movable blade can move closer to or away from the fixed blade; the blade edge of the fixed blade is straight, and the blade edge of the movable blade is hook-shaped.
[0006] The number of fixed blades is two, which are arranged symmetrically relative to the movable blades.
[0007] The front end of the base is also provided with a guide groove for guiding the movable blade.
[0008] The movable blade is connected to the push rod end of the push rod motor via a connecting pin.
[0009] In summary, the technical effects and advantages of this utility model are as follows:
[0010] In this invention, the wire to be cut is placed into the cutting edge of the movable blade, and the push rod motor drives the movable blade to move backward. The wire is cut by the movable blade and the fixed blade. Because the cutting edge of the movable blade is designed in a hook shape, the wire can remain stable during the cutting process and will not slip off the movable blade. In addition, through the cooperative work with the two fixed blades, the wire can be reliably cut in one go. After the cutting is completed, the entire wire cutter only needs to be reset to be ready for the next use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0018] like Figures 1-4As shown, the wire cutter used in this remote-controlled bomb disposal equipment includes a hollow base 3, a fixed blade 2 installed at the front end of the base 3, a movable blade 4 that cooperates with the fixed blade 2 slidably installed at the front end of the base 3, and a push rod motor 1 installed at the rear end of the base 3. The push rod motor 1 is electrically connected to the control box of the remote-controlled bomb disposal equipment through a circuit. In practice, the wire cutter can be installed on the remote-controlled bomb disposal equipment using existing technology. The connection between the push rod motor 1 and the control box of the remote-controlled bomb disposal equipment through a circuit is also existing technology, and its circuit does not need to be redesigned. The push rod end of the push rod motor 1 is connected to the movable blade 4, and under the action of the push rod motor 1, the movable blade 4 can move closer to or away from the fixed blade 2. The blade edge of the fixed blade 2 is straight, and the blade edge of the movable blade 4 is hook-shaped. With this structure, after the wire is inserted into the movable blade 4, as the movable blade 4 moves, the blade edge of the movable blade 4 will contact the base. Thus, before cutting, a closed cutting area is formed between the movable blade 4 and the fixed blade 2, and the wire is not easy to slip off the movable blade 4, ensuring the reliability and stability of the cutting operation.
[0019] There are two fixed blades 2, which are arranged symmetrically relative to the movable blades 4.
[0020] The base 3 also has a guide groove 3a at the front end for guiding the movable blade 4. With this structure, the guide groove 3a can make the movable blade 4 move more smoothly and reliably.
[0021] The movable blade 4 is connected to the push rod end of the push rod motor 1 via the connecting pin 5. With this structure, the movable blade 4 can be easily disassembled and replaced simply by removing the connecting pin 5.
[0022] In this invention, the wire to be cut is placed into the cutting edge of the movable blade 4, and the push rod motor 1 drives the movable blade 4 to move backward. The wire is cut by the movable blade 4 and the fixed blade 2. Because the cutting edge of the movable blade 4 is designed in the shape of a hook, the wire can remain stable during the cutting process and will not slip off the movable blade 4. In addition, through the cooperative work with the two fixed blades 2, the wire can be reliably cut in one go. After the cutting is completed, the entire wire cutter only needs to be reset and is ready for the next use.
[0023] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.
[0024] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
