The upper and lower ends of the two groups of limit blocks 6 are The ends are provided with limit grooves 10, and the two groups of mounting blocks 9 are movably connected with the two groups of limit grooves 10 respectively. The limit block 6 drives the mounting block 9 to move, thereby driving the supporting block 7 to move. A driving motor 4 is installed inside the demolition tool body 1, and the output end of the driving motor 4 is connected to one end of the driving shaft 5. The driving motor 4 drives the driving shaft 5 to rotate. A mounting port is provided at the upper end of the demolition tool body 1 to install a battery panel 18, and the battery panel 18 is electrically connected to the driving motor 4, and the battery panel 18 provides power to the driving motor 4.

[0033] See also Figure 1 - Figure 5The upper end of the slide groove 2 is symmetrically installed with a limit plate 3, and the inner walls of the multiple groups of limit plates 3 are movably connected to the outer walls of the upper ends of the multiple groups of protrusions 8. The inner walls of the two groups of limit grooves 10 are installed with magnetic blocks, and the insides of the two groups of mounting blocks 9 are installed with tooth blocks that attract the magnetic blocks on the inner walls of the two groups of limit grooves 10. The two groups of mounting blocks 9 are installed into the two corresponding groups of limit grooves 10, and the internal magnets of the two groups of mounting blocks 9 are attracted to the magnetic blocks on the inner walls of the two groups of limit grooves 10 respectively, so that the mounting blocks 9 are initially fixedly connected to the limit grooves 10. When the two groups of support blocks 7 move, the protrusions 8 move to the lower end of the limit plate 3, further strengthening the connection between the support block 7 and the limit block.

[0034] See also Figure 1 - Figure 4 The outer wall of the driving shaft 5 is provided with a bidirectional thread groove, and the inner walls of the two sets of limit blocks 6 are threadedly connected to the outer wall of the driving shaft 5. When the driving shaft 5 rotates, the two sets of limit blocks 6 are driven to move relative to each other.

[0035] See also Figure 1 - Figure 6 A second mounting groove 16 is provided at one end of the demolition tool body 1, and a drill bit 12 is movably installed inside the second mounting groove 16. A movable block 13 is installed at one end of the drill bit 12, and a rubber protective layer is provided on the outer wall of the movable block 13. Through the setting of the movable block 13, the drill bit 12 is installed into the second mounting groove 16 and is limited and fixed.

[0036] See also Figure 4 - Figure 6 A slot 11 is provided at one end of the driving shaft 5, and the cross-section of the slot 11 is hexagonal. A block 14 is installed at one end of the movable block 13, and the block 14 is matched and connected with the slot 11. The block 14 is installed into the inside of the slot 11, so that the drill bit 12 is connected to the driving shaft 5.

[0037] See also Figure 1 - Figure 2 The outer wall of the rescue tool body 1 is symmetrically provided with third mounting grooves 17, and two groups of third mounting grooves 17 are respectively installed with battery panels 18. Through the battery panels 18 inside the third mounting grooves 17, the number of backup power supplies is increased, and the use time of the rescue tool is improved.

[0038] See also Figure 1 - Figure 2 The outer wall of the demolition tool body 1 is symmetrically provided with operation grooves 19, and an operation switch electrically connected to the drive motor 4 is installed in a group of the operation grooves 19. The rescue personnel hold the demolition tool body 1 through the operation grooves 19 and control the drive motor 4 through the operation switches.

[0039] The working principle of the utility model is as follows: when the rescue tool is used at the rescue site, the rescue personnel respectively engage the two groups of support blocks 7 into the two groups of first installation grooves 15, thereby reducing the volume of the rescue tool body 1, making it easier for the rescue personnel to carry the rescue tool into the rescue site;

[0040] When performing rescue operations, if it is found that the distance between the obstacles is not enough to put one end of the two groups of support blocks 7 in, the rescuer takes out the drill bit 12 from the second installation slot 16, and then connects the clamping block 14 with the clamping slot 11, so that the drill bit 12 is connected to the drive shaft 5. The rescuer picks up the rescue tool body 1 through the operating slot 19 and aligns the drill bit 12 with the adjacent parts of the two groups of obstacles. The driving motor 4 is started through the operating switch inside the operating slot 19, thereby driving the drive shaft 5 and the drill bit 12 to rotate, and the drill bit 12 partially breaks the obstacles, thereby increasing the space between the obstacles;

[0041] When the space between the obstacles is large enough to accommodate the two groups of support blocks 7, the rescuer removes the drill bit 12 and puts it back into the second installation groove 16, then starts the drive motor 4 to drive the drive shaft 5 to rotate, and the inner walls of the two groups of limit blocks 6 are threadedly connected to the outer wall of the drive shaft 5, so the two groups of limit blocks 6 are displaced. After the two groups of limit blocks 6 move to the center of the slide groove 2, the rescuer turns off the drive motor 4 and takes out the two groups of support blocks 7 from the two groups of first installation grooves 15 respectively;

[0042] After the two groups of support blocks 7 are taken out from the two groups of first installation grooves 15, the rescue personnel respectively install the two groups of installation blocks 9 into the two groups of corresponding limit grooves 10, and the internal magnets of the two groups of installation blocks 9 are respectively attracted to the magnetic blocks on the inner walls of the two groups of limit grooves 10, so that the installation blocks 9 and the limit grooves 10 are initially fixedly connected. Then the rescue personnel put one end of the two groups of support blocks 7 between the obstacles, and the rescue personnel start the driving motor 4. The two groups of limit blocks 6 are displaced, driving the two groups of support blocks 7 to be displaced, and the obstacles are expanded. When the two groups of support blocks 7 move, the protrusion 8 moves to the lower end of the limit plate 3, further strengthening the connection between the support block 7 and the limit block.
