The second connecting portion 122 is provided with a through groove 1221 extending along a first direction, where the first direction is a direction from a side of the second connecting portion 122 facing the first connecting portion 121 to a side facing the driving member 123. When the second connecting portion 122 is sleeved on the first connecting portion 121, the through groove 1221 is communicated with the limit groove 1211, and since the limit piece 124 is movably disposed in the through groove 1221 and the length of the limit piece 124 in the first direction is greater than the length of the limit groove 1211 in the first direction, when the driving piece 123 slides to the first position, the driving piece 123 can drive the limit piece 124 to be partially clamped into the limit groove 1211, one part of the limit piece 124 is disposed in the limit groove 1211, the other part is disposed in the through groove 1221, and the first connecting portion 121 and the second connecting portion 122 are relatively fixed with each other, so that the connection strength is relatively strong. The first position is a position where the driving member 123 slides to push the limiting member 124 to be partially clamped in the limiting groove 1211.

The second position is a position where the driving member 123 slides to a position where the limiting member 124 moves away from the limiting groove 1211 in a direction away from the first connecting portion 121.

The breaking and disassembling device 10 of the embodiment of the present application has a limiting groove 1211 with a first inclined surface 127 and a second inclined surface 128, and a distance between one ends of the first inclined surface 127 and the second inclined surface 128, which are close to the output shaft 111, is smaller than a distance between one ends facing away from the output shaft 111. When the first connecting portion 121 and the second connecting portion 122 are separated, the first inclined surface 127 and the second inclined surface 128 can push the limiting member 124 to quickly retract into the through groove 1221, so that the first connecting portion 121 and the second connecting portion 122 can be quickly separated, and the dismounting efficiency is improved.

Further, the caliber of the side of the through groove 1221 facing the first connecting portion 121 is smaller than the maximum width of the limiting member 124, at this time, since the width of the limiting member 124 is larger than the caliber of one end of the through groove 1221, when the limiting groove 1211 is opposite to the through groove 1221, the limiting member 124 may be partially located in the limiting groove 1211, but the limiting member 124 will not be separated from the through groove 1221. When the first connecting portion 121 and the second connecting portion 122 are separated, the limiting member 124 can be stably located in the through groove 1221, and cannot be separated from the through groove 1221, so that stability of the limiting member 124 in the structure is ensured, and loss of the limiting member 124 is avoided. At this time, when the rescue personnel dismantles the work, also need not to break away from because of the locating part 124 and can't realize the installation, this structure has practiced thrift more time for the rescue process, has improved the efficiency of rescue.

The sliding seat 1232 is slidably disposed on the outer side of the second connecting portion 122, and the sliding seat 1232 further includes a protrusion 1235 and a sliding groove 1234 facing the first connecting portion 121. One end of the elastic member 1231 is disposed on the second connecting portion 122, and the other end is disposed on the sliding seat 1232. The elastic member 1231 pushes the sliding seat 1232 to move to the first position, at this time, the protrusion 1235 is opposite to the through groove 1221, and the protrusion 1235 pushes the limiting member 124, so that a part of the limiting member 124 is located in the through groove 1221, another part of the limiting member is located in the limiting groove 1211, and the first connecting portion 121 and the second connecting portion 122 are relatively fixed, so that the connection strength is relatively strong. When the elastic member 1231 pushes the sliding seat 1232 to move to the second position, the sliding groove 1234 is opposite to the through groove 1221, the limiting member 124 can be separated from the limiting groove 1211 and located in the through groove 1221 and the sliding groove 1234, the first connecting portion 121 and the second connecting portion 122 are separated, at this time, the limiting member 124 does not cross the limiting groove 1211 and the through groove 1221 any more, and the limiting member 124 can completely withdraw from the limiting groove 1211, so as to ensure that the first connecting portion 121 and the second connecting portion 122 are separated smoothly. At this time, the breaking and dismantling device 10 is more stable in structure in the rescue process, and is beneficial to the rescue work of rescue workers. However, when the sliding seat 1232 moves to the second position against the elastic force of the elastic member 1231, the sliding groove 1234 is disposed opposite to the through groove 1221, and the sum of the lengths of the sliding groove 1234 and the through groove 1221 in the first direction is greater than the length of the limiting member 124 in the first direction. The sliding groove 1234 provides the space for the stopper 124 to exit the limiting groove 1211, so that the stopper 124 can be completely located between the through groove 1221 and the sliding groove 1234, and cannot fall off, so as to ensure the stability of the stopper 124 when the first connecting portion 121 and the second connecting portion 122 are separated. In this application, sliding seat 1232 and elastic component 1231 make whole broken equipment 10 structure of tearing open more stable to locating part 124 can not drop from coupling assembling 12, consequently also can not cause the rescue personnel to appear the condition that the part is lost when installing new broken equipment 10 of tearing open, guaranteed broken normal work of tearing open equipment 10, improved rescue efficiency.

In some embodiments, the length of the sliding groove 1234 in the first direction is smaller than the length of the limiting element 124 in the first direction, when the sliding base 1232 moves to the second position against the elastic force of the elastic element 1231, at this time, a part of the limiting element 124 is located in the through groove 1221, another part of the limiting element 124 is located in the sliding groove 1234, and the limiting element 124 can avoid being separated from the through groove 1221 when being withdrawn from the limiting groove 1211, so that the limiting element 124 is lost. Therefore, when the stopper 124 exits the stopper groove 1211, the stopper 124 can be positioned between the through groove 1221 and the sliding groove 1234 to ensure the stability of the stopper 124, preventing the stopper 124 from being separated from the through groove 1221.

In the breaking and disassembling device 10 of the present embodiment, the second connecting portion 122 forms the clamping groove 126 toward one end of the breaking and disassembling device 13, one end of the elastic member 1231 is disposed in the clamping groove 126, and the other end is disposed in the sliding seat 1232. When the sliding seat 1232 moves to the first position, one end of the sliding seat 1232 is slidably disposed in the clamping groove 126. At this time, the sliding seat 1232 is located in the clamping groove 126 and cannot be separated from the clamping groove 126, so that the whole structure is more stable. In addition, one end of the elastic member 1231 is disposed in the clamping groove 126, and the other end of the elastic member is disposed in the sliding seat 1232, so that the elastic member 1231 can be effectively protected, and the elastic member 1231 is prevented from being exposed outside for a long time, so that the elastic member 123 cannot be driven back and forth under the action of elastic potential energy of the elastic member 1231, and therefore the first connecting portion 121 and the second connecting portion 122 cannot be rapidly connected and disconnected.

The breaking and disassembling device 10 of the present embodiment further includes a limiting ring 125, wherein the limiting ring 125 is of a rigid structure, and has strong stability, and the limiting ring 125 is disposed on the second connecting portion 122 and faces one side of the sliding seat 1232, so as to limit the movement of the protruding block 1235 on the second connecting portion 122 toward the sliding seat 1232.

And, lead to groove 1221 and be located between draw-in groove 126 and the spacing ring 125, when elastic component 1231 promotes the sliding seat 1232 and removes to lug 1235 butt spacing ring 125, the one end that sliding seat 1232 is close to draw-in groove 126 still is located draw-in groove 126, and sliding seat 1232 can not break away from this moment, and overall structure is more stable.

Further, the connection surface between the protrusion 1235 and the sliding groove 1234 is configured as a slope 129, the slope 127 is inclined toward the second connection portion 122, and a distance between an end point of the slope 129 near the end of the second connection portion 122 and the clamping groove 126 is smaller than a distance between an end point far from the end of the second connection portion 122 and the clamping groove 126. Therefore, when the sliding seat 1232 slides to enable the limiting member 124 to be located in the limiting groove 1211, the inclined surface 129 pushes the limiting member 124 to be clamped into the limiting groove 1211, and when the inclined surface 127 abuts against the limiting ring 125, the sliding seat 1232 stops sliding. At this time, the bump 1235 presses against the stopper 124, so that the stopper 124 is located in the stopper groove 1211 and the through groove 1221, thereby realizing the connection of the first connection portion 121 and the second connection portion 122. Therefore, when rescue workers perform work, the connection between the breaking and disassembling device 10 and the connecting assembly 12 is more stable, so that the rescue efficiency is effectively improved.
