Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic cutting machine equipment, in particular to a portable multifunctional air-breathing pneumatic cutting machine. Background Art

[0002] In firefighting and rescue operations, rescuers often have to face high-temperature toxic gases to carry out demolition and obstacle clearance operations. Therefore, rescuers must wear personal protective equipment, carry air respirators to provide necessary life support, and use cutting machines to carry out operations. For example, in handling fires in residential buildings, when setting up ladders to rescue trapped people on the second or third floors, they often encounter obstacles such as anti-theft windows. Rescuers need to carry bulky toothless saws for demolition, which involves complicated operations and a high risk of falling.

[0003] In the prior art, the air respirator and the cutting machine are two different sets of equipment. In actual use, firefighters need to carry both equipment at the same time to enter the rescue site for rescue operations, which is not convenient enough. For example, the authorized patent document with application number CN202322255797.7 discloses a split fire-fighting cutting machine. It includes a cutting machine, and also includes: a power connection socket, which is arranged on the top of the motor of the cutting machine and is electrically connected to the motor; a data line, the power connection socket is electrically connected to the external lithium battery pack through the data line; the two ends of the data line include a connected male plug connector and a female plug connector; the male plug connector includes: a male shell, a conductive column and a positioning pin a; two conductive columns are symmetrically plugged into the male shell, and one positioning pin a is plugged into the male shell and is located between the two conductive columns; the female plug connector includes: a female shell, a conductive slot and a positioning pin b; two conductive slots are symmetrically plugged into the female shell. The lithium battery is separated from the cutting machine by the data cable and arranged outside, which reduces the overall weight of the cutting machine and thus reduces the labor intensity of the operators.

[0004] The above patent states that the air respirator and the cutter are two different sets of equipment. In actual use, firefighters need to carry both types of equipment to enter the rescue site for rescue operations, which is not convenient enough. Therefore, we need to provide a portable multifunctional air-breathing pneumatic cutter. Utility Model Content
