[0022] Reference Figure 1-Figure 4 A fire rescue and demolition device includes a handheld stick body 1 which is a prior art and is made of a lightweight aluminum alloy material. While improving its own strength, it has a higher supporting capacity. The hammer head body 2 is a hammer in the prior art. A groove 3 is opened at the tail end of the handheld stick body 1, which is convenient for firefighters to grab and maximize the function of the device. The knob 4 is only used for adjustment function.

[0023] The hammer body 2 is symmetrically provided with an impact cone 5 for impacting the waste, which is used to increase the impact force of the hammer body 2 impacting the waste, increase the effect of breaking the waste into pieces, and reduce the impact loss of the hammer body 2. The impact cone 5 is fixedly connected to the hammer body 2 by welding, and the connection ability between the two can be improved by welding. The hammer body 2 is fixedly connected to the handheld stick body 1 through an auxiliary compression shaft, and the auxiliary compression shaft is composed of a telescopic shaft and a compression spring. While maintaining a tight connection, it can also play a role in buffering the impact force. The hammer body 2 is symmetrically provided with auxiliary support shafts, which are set on both sides of the hammer body 2 to alleviate the impact force brought by the buffer body 6 and prevent the buffer body 6 from directly hitting the hammer body 2.

[0024] A buffer body 6 for alleviating impact force is provided on the vertical hammer head body 2. The buffer body 6 is made of rubber material, which has low cost and strong buffering capacity. The buffer body 6 is fan-shaped, and both ends are against the auxiliary support shaft, and the two are in a tight state. When the buffer body 6 is impacted, deformation will occur, and with the support of the auxiliary support shaft, the recovery rate after deformation is improved. The buffer body 6 is fixedly connected to the hammer head body 2 through the central spring shaft 7, and the central spring shaft 7 passes through the hammer head body 2 and is connected to the auxiliary compression shaft.

[0025] An inner cavity 10 is provided in the handheld stick body 1, and the inner cavity 10 is used to provide a later adjustment component, and the interior is coated with lubricating industrial butter to maintain the internal operating efficiency. A first central axis 12 and a second central axis 13 are provided in the inner cavity 10. The first central axis 12 is arranged at the end facing the knob 4, and the second central axis 13 is longer as a whole and is arranged at the end facing the hammer head body 2, and the two are fixedly connected by welding, and welding can improve the connection ability.

[0026] The buffer body 6 is symmetrically provided with a pushing body 8 for propping up the waste. The pushing body 8 is used to pry open the waste, improve the rescue ability of the firefighters, and give full play to the ability of one object to serve multiple purposes. The pushing body 8 can temporarily replace the role of the jack with the cooperation of the hydraulic cylinder 9. One end of the pushing body 8 is fixedly connected to the buffer body 6 through an auxiliary shaft. The auxiliary shaft is arranged at the rear end of the pushing body 8 and is fixed above the buffer body 6, and the pushing body 8 is rotatably connected on the auxiliary shaft. The pushing body 8 can only rotate to both sides by being pushed by the hydraulic cylinder 9. A hydraulic cylinder 9 for rotation is provided on the pushing body 8. The hydraulic cylinder 9 is a telescopic booster component, and the hydraulic cylinder 9 is fixedly connected to the central spring shaft 7. Both ends of the hydraulic cylinder 9 pass through the pushing body 8 and are connected to the central spring shaft 7 through the hydraulic component.

[0027] An adjusting ring 11 for adjusting the pushing body 8 is provided in the inner cavity 10, and the adjusting ring 11 is used to lock the current angle of the hydraulic cylinder 9, thereby playing a role of limiting and fixing. The first central axis 12 is fixedly connected to the knob 4, and the knob 4 is fixed to the first central axis 12 by welding. The adjusting ring 11 is adapted to the first central axis 12, and the side wall of the first central axis 12 is against the adjusting ring 11, and a plurality of calipers are provided on the adjusting ring 11, and the calipers are used to capture the rotation movement of the first central axis 12, so that the calipers of the adjusting ring 11 are against and fit with the first central axis 12, thereby achieving a fixing effect, and the second central axis 13 is adapted to the auxiliary compression shaft, and the second central axis 13 is fixed to the auxiliary compression shaft by welding.

[0028] The working principle of the utility model is as follows: the firefighter holds the stick body 1 with both hands according to the on-site conditions and hits the waste in front. During the hitting process, the impact cone 5 will increase the impact effect and improve the splitting state of the waste. In order to improve the displacement and pushing work of the stacked waste, the pushing body 8 is embedded between two wastes, and the knob 4 is turned to extend the length of the hydraulic cylinder 9, so that the pushing body 8 rotates to both sides, forcing the waste on both sides to separate from each other and improving the rescue efficiency of the firefighters.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
