[0013] As a further description of the above technical solution:

[0014] The cutting pad is made of 304 stainless steel.

[0015] As a further description of the above technical solution:

[0016] Both ends of the air supply hose are respectively equipped with internal threaded connectors that can be spirally connected to the air outlet helical tube and the air inlet helical tube.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] This utility model discloses a pneumatic metal cutter consisting of four main parts: a high-pressure gas cylinder, a storage box, a pneumatic grinder, and an air supply hose. When not in use, the pneumatic grinder, air supply hose, and cutting pad can be stored between the storage box and its lid. The high-pressure gas cylinder is then concealed between the four support legs of the storage box. Rescuers can easily handle and transport the entire pneumatic metal cutter by gripping the handle. During actual cutting, the air supply hose is installed between the high-pressure gas cylinder and the pneumatic grinder, and the control valve can be operated to control the pneumatic grinder to cut rings, bracelets, or other jewelry worn by the person being rescued. This metal cutter has a reasonable overall layout and compact structure, making it convenient for rescuers to carry and use. Furthermore, rescuers can operate the pneumatic grinder with one hand, effectively reducing the workload and difficulty of cutting rescues, thereby improving the convenience and efficiency of actual cutting rescues.

[0024] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a portable pneumatic metal cutter, including a high-pressure gas cylinder 1, a pneumatic air grinder 3, and an air supply hose 4. The upper end of the high-pressure gas cylinder 1 is detachably equipped with a storage box 2 for storing the pneumatic air grinder 3 and the air supply hose 4. The upper end of the storage box 2 is rotatably equipped with a box cover 202. The right end of the high-pressure gas cylinder 1 is equipped with a control valve 101, and the right end of the control valve 101 is equipped with a pressure gauge 103. The front end of the control valve 101 is connected to an outlet solenoid 102. The front end of the pneumatic air grinder 3 is rotatably equipped with a cutting blade 301, and the rear end of the pneumatic air grinder 3 is connected to an inlet solenoid 302.

[0026] Specifically, such as Figure 1-3 As shown, the four corners at the bottom of the storage box 2 are all fixedly connected with support legs 201 that engage with the outer wall of the high-pressure gas cylinder 1. On the one hand, the storage box 2 can be supported to a certain height off the ground, making it convenient for rescuers to take tools out of the storage box 2. On the other hand, the high-pressure gas cylinder 1 can be hidden and installed under the storage box 2, improving the overall space utilization of the pneumatic metal cutter.

[0027] Specifically, such as Figure 1-3 As shown, a handle 203 is fixedly connected to the upper middle part of the lid 202, which facilitates rescuers to hold, pick up, and transport the storage box 2.

[0028] Specifically, such as Figure 2 and Figure 3 As shown, the inner side of the storage box 2 is provided with a cutting pad 5 to prevent the cutting blade 301 from directly contacting the limb.

Rescuers can hold the handle 203 on the lid 202 to pick up, place, and transport the pneumatic metal cutter as a whole. After arriving at the rescue location, the storage box 2 can be placed on the ground or table using the support legs 201. Then, the lid 202 can be unlocked and unscrewed to access the pneumatic grinder 3, air hose 4, cutting pad 5, or other cutting aids. Take out the air hose 4, cutting pad 5, or other cutting aids from the storage box 2, and then screw the internal threaded connectors 401 at both ends of the air hose 4 between the air outlet screw pipe 102 and the air inlet screw pipe 302 respectively. At this time, the air circuits of the high-pressure gas cylinder 1 and the pneumatic grinder 3 can be connected. The rescuer can adjust the speed of the pneumatic grinder 3 by controlling the opening and closing of the control valve 101. The rescuer can hold the pneumatic grinder 3 with one hand and place the cutting pad 5 between the object to be cut and the limb with the other hand. Then the object to be cut can be cut by the rotating cutting blade 301.
