[0002] With the rapid development of our country over the years, the number of buildings has increased year by year, and many buildings need to be demolished and repaired. Demolition tools can be used in construction projects to demolish concrete structures, temporary supports and other related buildings. Demolition tools include but are not limited to manual demolition tools such as pry axes, pickaxes, shovels, knives, axes, etc., electric demolition tools such as electric saws, electric drills, electric welders, etc. Other major demolition tools include expanders, jacks, etc.

[0003] Demolition tools usually need to handle complex on-site conditions and need to carry tools for multiple purposes. For example, it is necessary to pry open huge rocks and other heavy objects, and then perform demolition operations underneath the heavy objects. Although traditional demolition tools also carry equipment such as expanders and jacks to support heavy objects, the expansion stroke of traditional expanders is relatively small, and jacks need to be coordinated to stabilize the working surface to facilitate the operator to perform the next step. Traditional handheld demolition equipment is difficult to meet the working requirements of this special situation. Generally, large-scale lifting equipment is required to cooperate on site to work, which greatly increases the difficulty of operation. In addition, traditional demolition tools are generally stored in ordinary tool boxes. Although they can meet basic carrying requirements, they are not flexible to use and cannot meet the needs of demolition tools to cope with complex scenarios. Summary of the invention

The rotation of the two threaded rods 311 drives the display board 33 to rise and fall vertically in the box body 31, so that the lifting of the display board 33 is more stable. When the driving rod 521 slides horizontally toward the rear side of the box body 31, the driving rod 521 can drive the driving gear 3111 to rotate forward, thereby driving the display board 33 to rise vertically in the box body 31. When the driving rod 521 slides horizontally toward the front side of the box body 31, the driving rod 521 can drive the driving gear 3111 to rotate reversely, thereby driving the display board 33 to descend vertically in the box body 31. The arrangement of the accessory compartment 313 can facilitate the storage of other smaller demolition tools in the box body 31 .

[0038] like Figure 2 , Figure 7 and Fig.13 - Fig.17As shown, the lifting mechanism 4 includes an upper top plate 41, a lower top plate 42, a support frame 43, a double screw 44, a slider 45, an upper connecting rod 46 and a lower connecting rod 47.

A bit 531 is provided at one end of the adapter rod 53 away from the cutting mechanism 5, and the bit 531 can be engaged in the straight groove 481.

[0039] In this embodiment, when the double screw 44 rotates in the support frame 43, the two sliders 45 slide horizontally in the support frame 43. The symmetrically arranged threads enable the two sliders 45 to slide horizontally close to each other in the support frame 43, or the two sliders 45 to slide horizontally away from each other in the support frame 43 when the double screw 44 rotates in the support frame 43. The two sliders 45 slide horizontally close to each other in the support frame 43, and can drive the upper top plate 41 and the lower top plate 42 to move vertically away from the support frame 43 through the upper connecting rod 46 and the lower connecting rod 47, that is, drive the jacking mechanism 4 to rise, and the two sliders 45 slide horizontally away from each other in the support frame 43, and can drive the upper top plate 41 and the lower top plate 42 to move vertically close to the support frame 43 through the upper connecting rod 46 and the lower connecting rod 47, that is, drive the jacking mechanism 4 to fall; The transmission bevel gear 49 rotates to drive the twin screws 44 to rotate, and the drive interface 442 and the avoidance hole 432 are arranged so that the twin screws 44 can be directly connected to the drive mechanism, thereby directly driving the twin screws 44 to rotate; When the electric cutting machine 51 rotates, the transfer rod 53 is driven to rotate, and the transfer rod 53 can drive the transmission rod 48 to rotate, the transmission rod 48 can drive the transmission bevel gear 49 to rotate, the transmission bevel gear 49 can drive the double screw 44 to rotate, and the double screw 44 can drive the lifting mechanism 4 to rise and fall, that is, the rotation of the electric cutting machine 51 can drive the lifting mechanism 4 to rise and fall.

[0040] Working principle: When storing handheld electric demolition tools, electric drills and other handheld electric demolition tools can be placed in the storage box 3, and the cutting mechanism 5 can slide in the storage compartment 2, so that a variety of electric handheld demolition tools can be stored in the protection box 1, which is convenient to carry. The storage compartment 2 is composed of a detachable movable plate, which can be removed during work, which is not only convenient for taking out the handheld electric demolition tools in the storage compartment 2, but also allows the two storage boxes 3 to form a separate storage box, which can be used flexibly, and the lifting mechanism 4 is fixed to both sides of the protection box 1 by bolts, which can also be removed and used separately, and finally realizes the integration of a variety of demolition tools in the protection box 1, and a variety of demolition tools can be carried at one time during the demolition task, so that they will not be missed, which is convenient to use, and can be flexibly disassembled and transformed during use to adapt to different working conditions; When the top cover 32 slides on the top of the box body 31 and completely covers the top of the box body 31, the pressure plate is pressed on the locking plate, and then the display plate 33 is completely fixed. Then, by installing a lock on the lock hole, the handheld electric rescue tool in the box body 31 can be locked. At this time, the rack of the driving rod 521 is engaged with the driving gear 3111, the display plate 33 is fixed, that is, the driving rod 521 is fixed in the guide rail 315, and the driving rod 521 cannot slide horizontally, that is, the cutting mechanism 5 is fixed in the storage bin 2, which effectively protects the storage bin 2 and the handheld electric rescue tool stored in the storage box 3, and is convenient for carrying the handheld electric rescue tool; When using the demolition tool, the movable plates are removed in order, the storage compartment 2 is opened, and then the top cover 32 is removed from the top of the box body 31. Then, the electric cutting machine 51 is pushed and pulled to drive the driving rod 521 on the bracket 52 to slide horizontally in the guide rail 315. The horizontal sliding of the driving rod 521 can drive the driving gear 3111 to rotate, and the rotation of the driving gear 3111 can drive the threaded rod 311 on the rear side of the box body 31 to rotate. At the same time, the rotation of the threaded rod 311 on the rear side of the box body 31 can drive the threaded rod 311 on the front side of the box body 31 to rotate through the transmission chain 34. When the driving rod 521 slides horizontally toward the rear side of the box body 31, the driving rod 521 can drive the driving gear 3111 to rotate forward, thereby driving the display board 33 to rise vertically in the box body 31. When the driving rod 521 slides horizontally toward the front side of the box body 31, the driving rod 521 can drive the driving gear 3111 to rotate reversely, thereby driving the display board 33 to descend vertically in the box body 31. Thus, it is convenient to take out the handheld electric demolition tool from the box body 31, and the two threaded rods 311 rotate to drive the display board 33 to vertically rise and fall in the box body 31, so that the lifting of the display board 33 is more stable; In a special working condition where a heavy object needs to be supported and then a demolition operation is performed, the electric cutter 51 is pulled backward so that the bit 531 can be stuck in the straight groove 481, and the electric cutter 51 is started. When the electric cutter 51 rotates, the transfer rod 53 is driven to rotate, and the transfer rod 53 can drive the transmission rod 48 to rotate, and the transmission rod 48 can drive the transmission bevel gear 49 to rotate, and the transmission bevel gear 49 can drive the double screw 44 to rotate; When the double screw 44 rotates in the support frame 43, the two sliders 45 slide horizontally in the support frame 43. The symmetrically arranged threads enable the two sliders 45 to slide horizontally close to each other in the support frame 43 when the double screw 44 rotates in the support frame 43, or the two sliders 45 slide horizontally away from each other in the support frame 43; The two sliders 45 slide horizontally close to each other in the support frame 43, and can drive the upper top plate 41 and the lower top plate 42 to move vertically away from the support frame 43 through the upper connecting rod 46 and the lower connecting rod 47, that is, drive the jacking mechanism 4 to rise, and the two sliders 45 slide horizontally away from each other in the support frame 43, and can drive the upper top plate 41 and the lower top plate 42 to move vertically close to the support frame 43 through the upper connecting rod 46 and the lower connecting rod 47, that is, drive the jacking mechanism 4 to fall, so that the rotation of the double screw 44 can drive the jacking mechanism 4 to rise and fall, that is, the rotation of the electric cutting machine 51 can drive the jacking mechanism 4 to rise and fall; The setting of the drive interface 442 and the avoidance hole 432 allows the double screw 44 to be directly connected to the drive mechanism, thereby directly driving the double screw 44 to rotate. The jacking mechanism 4 on one side of the protective box 1 can be driven to rise and fall by the electric cutting machine 51, and the jacking mechanism 4 on the other side of the protective box 1 can be driven to rise and fall by other electric tools such as an electric drill, so that the jacking mechanisms 4 on both sides of the protective box 1 can lift the heavy objects, form a stable working space at the location of the protective box 1, and reinstall the upper slide plate 21 in place. The operator can push the electric cutting machine 51 horizontally in the storage bin 2 to perform demolition operations under the heavy objects, effectively ensuring the operator's operating safety.
