Description

Technical Field

[0001] This utility model relates to the field of emergency rescue technology, and in particular to a portable pneumatic puncture and demolition tool. Background Technology

[0002] Among pneumatic piercing and demolition tools, the portable finger tool, through the selection of lightweight materials and compact structural design, keeps the overall weight within a range that is easy for a single person to carry. Its small size allows it to be easily stored in a rescue equipment box, meeting the flexible mobility needs in complex rescue scenarios. Pneumatic means that it uses compressed air as a power source, converting compressed air into kinetic energy through an air pump. It does not rely on electricity or fuel and can stably output power in various environments. Piercing and demolition means that it uses a sharp piercing head at the front end to pierce through hard obstacles such as security doors and steel bars through high-frequency impact and continuous pressure, thereby quickly opening up passages.

[0003] Pneumatic piercing and demolition tools are mainly used for emergency rescue, breaking through obstacles such as security doors and steel bars to open rescue channels. In the existing technology, the piercing head is driven by the air pressure provided by the air pump through manual operation, and is kept stable with the help of the support rod component. However, the existing technology has problems. The filter mechanism is inconvenient to clean, which leads to air intake obstruction. This problem results in poor tool working stability, low demolition efficiency, delay in rescue, and inability to work normally due to malfunction. Utility Model Content

The inner wall of the filter screen 208 is rotatably connected to the outer wall of the brush rod 207. The left side of the sealing ring 205 is fixedly connected to the right side of the fixed plate 203.

[0038] Specifically, the front support block 16 of the hollow column 201 fixes the controller 17, the controller 17 regulates the operation of the air pump 13, the bottom support leg 21 and foot pad 22 of the fixed frame 1 stabilize the tool, the filter screen 208 and the brush rod 207 rotate to facilitate cleaning, and the sealing ring 205 enhances the sealing of the fixed plate 203.
