[0022] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the housing 1 is composed of a housing body 101, a handle block 102 and a support 103. The front surface of the housing body 101 is fixedly connected to the back surface of the handle block 102. The front surface of the handle block 102 is fixedly connected to the back surface of the support 103. A sliding groove is provided on one side of the housing body 101. A working hole is provided on the back surface of the housing body 101. A locking hole and a battery cover groove are provided on the top of the housing body 101. The handle block 102 provides convenience for holding and facilitates the operation of the entire tool by the staff. The support 103 can stably place the tool on the ground when not in use.

[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the demolition member 2 includes a motor 201, a connecting shaft 202, a drill bit 203 and a lower fixing plate 204. The output end of the motor 201 is fixedly connected to one end of the connecting shaft 202. The other end of the connecting shaft 202 is fixedly connected to the front surface of the drill bit 203. The outer wall of the motor 201 near the bottom wall is slidably connected to the inner wall of the lower fixing plate 204. The outer wall of the connecting shaft 202 is rotatably connected to the inner wall of the working hole. The outer wall of the lower fixing plate 204 is fixedly connected to the inner bottom wall of the housing body 101. When the motor 201 is started, the output rotational power is transmitted to the connecting shaft 202, and the connecting shaft 202 then drives the drill bit 203 to rotate. The drill bit 203 demolishes the target object during rotation.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the locking member 3 is composed of an upper fixing plate 301, a threaded rod 302 and a dial 303. The inner wall of the upper fixing plate 301 is threadedly connected to the outer wall of the threaded rod 302 near the bottom end. The top end of the threaded rod 302 is fixedly connected to the bottom of the dial 303. The outer wall of the threaded rod 302 away from both ends is rotatably connected to the inner wall of the locking hole. The inner top wall of the upper fixing plate 301 is in movable abutment with the top of the motor 201. By rotating the dial 303, the threaded rod 302 is driven to rotate. When the threaded rod 302 rotates, the upper fixing plate 301 is restricted by the housing body 101 and cannot rotate with the threaded rod 302, and can only move up and down along its axis.

When the staff needs to adjust the distance that the drill bit 203 extends, by rotating the dial 303 to drive the threaded rod 302 to rotate, when the threaded rod 302 rotates, the upper fixing plate 301 is restricted by the housing 101 and cannot rotate with the threaded rod 302, and can only move upward along its axis, so that the clamping of the motor 201 by the upper fixing plate 301 and the lower fixing plate 204 becomes loose. At this time, the adjusting rod 403 is toggled to slide in the sliding groove. The sliding of the adjusting rod 403 drives the fixed disk 401 and the motor 201 to slide on the lower fixing plate 204, thereby changing the distance that the drill bit 203 extends. After the adjustment is completed, the dial 303 is rotated in the reverse direction to make the upper fixing plate 301 move downward and lock the motor 201 together with the lower fixing plate 204 to prevent the motor 201 from moving during operation. Adjusting the distance that the drill bit 203 extends can ensure that the staff maintains a safe distance during operation and reduces the operation risk.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 shown, the power supply member 5 is composed of a battery box 501, a box cover 502, and a clamping block 503. A box cover 502 is provided above the battery box 501. The front surface of the box cover 502 is fixedly connected to the back surface of the clamping block 503. The outer wall of the clamping block 503 is snap-connected to the inner wall of the housing 101. The outer wall of the box cover 502 is movably abutted against the inner wall of the battery cover groove. The outer side wall and the bottom of the battery box 501 are respectively movably abutted against the inner side wall and the inner bottom wall of the housing 101. After the electric demolition tool is used for a period of time, the staff can open the box cover 502 to conveniently remove the old battery and replace it with a new battery. The clamping block 503 ensures that the box cover 502 can be tightly fixed in the battery cover groove when it is closed, preventing the box cover 502 from accidentally opening or loosening, and also ensuring that the box cover 502 can be easily opened when needed, facilitating the use by the staff.

[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the protective member 6 includes an upper protective plate 601, a limit block 602, a lower protective plate 603 and a mounting plate 604, and the number of the limit blocks 602 is two, the bottom of the upper protective plate 601 near both sides is fixedly connected to the tops of the two limit blocks 602 respectively, and the outer walls of the two limit blocks 602 are movably connected to the inner walls of the lower protective plate 603, the backs of the upper protective plate 601 and the lower protective plate 603 are fixedly connected to the front of the mounting plate 604 by bolts, and the fronts of the upper protective plate 601 and the lower protective plate 603 are fixedly connected to the back of the shell 101, and the upper protective plate 601 and the lower protective plate 603 can be conveniently installed between the mounting plate 604 and the shell 101 by bolts, so that the demolition tools can effectively block the splashes generated during the demolition process when working, and prevent these splashes from hurting the staff.

[0028] The use method and advantages of the utility model: When the electric demolition tool for fire rescue is working, the working process is as follows:

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, the threaded rod 302 is driven to rotate by rotating the toggle plate 303. When the threaded rod 302 rotates, the upper fixed plate 301 is restricted by the shell 101 and cannot rotate with the threaded rod 302, and can only move upward along its axis, so that the clamping of the upper fixed plate 301 and the lower fixed plate 204 on the motor 201 is loosened. At this time, the adjusting rod 403 is toggled to slide in the sliding groove. The sliding of the adjusting rod 403 drives the fixed plate 401 and the motor 201 to slide on the lower fixed plate 204, thereby changing the extension distance of the drill bit 203. After the adjustment is completed, the toggle plate 303 is rotated in the opposite direction to make the upper fixed plate 301 move downward, and the motor 201 is locked together with the lower fixed plate 204 to prevent the motor 201 from moving during operation. Adjusting the extension distance of the drill bit 203 can ensure that the staff maintains a safe distance during work, thereby reducing the operation risk. The upper protective plate 601 and the lower protective plate 603 can be conveniently installed between the mounting plate 604 and the shell 101 by means of bolts, so that the demolition tool can effectively block the splashes generated during the demolition process when working, and prevent these splashes from injuring the staff. After the electric demolition tool has been used for a period of time, the staff can open the box cover 502, conveniently remove the old battery and replace it with a new one. The snap block 503 ensures that the box cover 502 can be tightly fixed in the battery cover slot when closed, preventing the box cover 502 from being accidentally opened or loosened, and also ensuring that the box cover 502 can be easily opened when needed, which is convenient for the staff to use.
