[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a demolition device.

[0037] Embodiment 1:

[0038] Reference Figure 1 and Figure 2 The breaker includes a limit seat 1, a cutter 2 and a transmission column 3. A limit slot 11 is provided at one end of the limit seat 1. The limit slot 11 is used to limit the nut. In the present embodiment, the limit slot 11 is provided in a circular shape to fit the shape of the nut and improve the stability of the nut limit. A connecting hole 12 is provided at the other end of the limit seat 1 along its length direction. The connecting hole 12 extends to the limit slot 11 so that the connecting hole 12 is connected to the limit slot 11. The cutter 2 is slidably connected to the connecting hole 12, the transmission column 3 is threadedly connected to the connecting hole 12, and the end of the cutter 2 away from the limit slot 11 is rotatably connected to the transmission column 3. The sliding of the cutter 2 can be achieved by rotating the transmission column 3.

[0039] In practical application, the limiting seat 1 is first sleeved on the rusty nut, so that the nut abuts against the groove wall of the limiting groove 11 to limit the nut. At this time, the cutter 2 is aligned with the nut cutting position, and then the transmission column 3 is rotated. The transmission column 3 drives the cutter 2 to slide and connect to the connecting hole 12, so that the cutter 2 abuts against the nut. Then the transmission column 3 is continued to be rotated, and the cutter 2 starts to cut the nut. In this process, only the transmission column 3 needs to be rotated to realize the cutting and disassembly of the nut. The operation is simple and convenient, so it is convenient to cut and disassemble the nut. In addition, since the transmission column 3 is threadedly connected to the connecting hole 12, and the cutter 2 is rotatably connected to the transmission column 3, the cutter 2 slowly cuts the nut, so that the cutter 2 stably cuts the nut, which can effectively reduce the occurrence of the cutter 2 breaking, so as to increase the service life of the cutter 2.

[0040] In some embodiments, an observation hole 13 is provided on one side of the limit seat 1, and the observation hole 13 is located at one end of the connection hole 12 close to the limit slot 11, so that the observation hole 13 is connected to the limit slot 11 and the connection hole 12 at the same time. Before the transmission column 3 is rotated, the cutter 2 is entirely located in the connection hole 12, and the observation hole 13 is provided to facilitate observation of the position of the cutter 2 close to the limit slot 11, so that the position of the nut limit in the limit slot 11 can be adjusted, so that the cutter 2 is accurately aligned with the cutting position of the nut.

[0041] Reference Figure 2 and Figure 3 In some embodiments, the cutter 2 is provided with a rectangular slide groove 21 along its length direction, and the limit seat 1 is located at the end of the connecting hole 12 close to the limit groove 11 and protrudes to form a slide bar 14. The shape of the slide bar 14 is adapted to the shape of the slide groove 21, so that the slide bar 14 slides and is limited in the slide groove 21, so that the cutter 2 can slide more stably along the length direction of the limit seat 1, so as to ensure that the cutter 2 can stably cut the nut, thereby improving the stability of the nut cutting.

[0042] Reference Figure 1 In some embodiments, the end of the transmission column 3 away from the cutter 2 is arranged in a regular hexagonal column shape. In practical applications, the transmission column 3 can be rotated by using tools, such as a hexagonal wrench cooperating with the end of the transmission column 3 away from the cutter 2, so that it is convenient for the staff to apply force to rotate the transmission column 3, and further facilitate the cutting and disassembly of the nut.

[0043] In some embodiments, a rotation groove 31 is provided at one end of the transmission column 3 away from the cutter 2. The rotation groove 31 is a regular hexagonal groove, and the transmission column 3 can be rotated by using a tool, such as an electric wrench that cooperates with the rotation groove 31, so as to facilitate the rotation of the transmission column 3, thereby further facilitating the cutting and disassembly of the nut.

[0044] The implementation principle of this embodiment is as follows: in actual application, the limit seat 1 is first sleeved on the rusty nut, so that the nut abuts against the groove wall of the limit groove 11 to limit the nut. At this time, the cutter 2 is aligned with the cutting position of the nut, and then the transmission column 3 is rotated. The transmission column 3 drives the cutter 2 to slide and connect to the connecting hole 12, so that the cutter 2 abuts against the nut, and then the transmission column 3 is continued to be rotated, and the cutter 2 starts to cut the nut. In this process, the nut can be cut and disassembled by only rotating the transmission column 3. The operation is simple and convenient, so it is easy to cut and disassemble the nut.

[0045] Furthermore, since the transmission column 3 is threadedly connected to the connecting hole 12, and the cutter 2 is rotatably connected to the transmission column 3, the cutter 2 slowly cuts the nut, and the cutter 2 stably cuts the nut, which can effectively reduce the occurrence of breakage of the cutter 2 and increase the service life of the cutter 2.

[0046] Embodiment 2:

[0047] Reference Figure 4 and Figure 5 , the other structures of this embodiment are the same as those of the embodiment 1, except that the cutter 2 includes a cutter head 22 and a cutter column 23, wherein a rotation groove 32 is provided at one end of the transmission column 3 close to the cutter column 23, and the cross section of the rotation groove 32 is set in a "T" shape, and correspondingly, the end of the cutter column 23 away from the limiting groove 11 is set in a "T"-shaped column and is located in the rotation groove 32, so as to realize the rotation of the cutter column 23 and limit it in the rotation groove 32, so as to limit the cutter column 23 from being separated from the transmission column 3, thereby ensuring the working stability of the cutter 2. At the same time, the cutter head 22 is detachably connected to the end of the cutter column 23 close to the limiting groove 11, and the cutter head 22 of different shapes can be replaced according to the actual working conditions to improve the applicability of the demolition device, and the damaged cutter head 22 can also be repaired to reduce the maintenance cost of the demolition device.

[0048] Reference Figure 5 In some embodiments, a plug-in column 221 is formed protruding from one end of the cutter head 22 near the cutter column 23, and a plug-in slot 231 is correspondingly provided at one end of the cutter column 23 near the cutter head 22. The plug-in column 221 is inserted into the plug-in slot 231 to realize a detachable connection between the cutter head 22 and the cutter column 23. In other embodiments, it can also be realized by a snap-on structure. Among them, the cutter 2 also includes a fastener 24, which is threadedly connected to the cutter column 23 and penetrates the plug-in column 221 to improve the installation stability between the cutter head 22 and the cutter column 23, so as to ensure the stability of the cutter 2 in cutting the nut. It should be noted that the fastener 24 is located in the cutter column 23 as a whole.

[0049] In some embodiments, a positioning column 222 is protruded from one end of the cutter head 22 near the cutter column 23, and a positioning groove 232 is opened at one end of the cutter column 23 near the cutter head 22. The positioning column 222 is inserted into the positioning groove 232 to achieve positioning installation between the cutter head 22 and the cutter column 23, thereby facilitating accurate installation of the cutter head 22 and the cutter column 23.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
