[0056] Further, the inner wall of the positioning arc block 9 is an inclined surface, and the sliding cone block 12 is slidingly connected between the four positioning arc blocks 9.

[0057] The electric push rod 19 is fixedly connected to the bottom wall of the mounting groove 2.

[0058] The upper end of the electric push rod 19 is fixedly connected to the lower surface of the sliding cone block 12.

[0059] The two sliding pipes 10 are fixedly connected to the inner walls of the corresponding two positioning arc blocks 9.

[0060] Further, the two sliding rods 11 are fixedly connected to the inner walls of the corresponding two positioning arc blocks 9, and the two sliding rods 11 slidingly extend into the two sliding pipes 10.

[0061] The two second springs 18 are fixedly connected between the corresponding two positioning arc blocks 9.

[0062] The second spring 18 is sleeved on the outer surfaces of the corresponding sliding rod 11 and sliding pipe 10.

[0063] The four mounting arc plates 7 are slidingly connected to the outer surfaces of the four positioning arc blocks 9.

[0064] Further, the four fixing blocks 15 are fixedly connected to the inner walls of the corresponding mounting arc plates 7.

[0065] The mounting rod 14 is sleeved on the corresponding fixing block 15.

[0072] Further, in the initial state, the first spring 5 is in a state of being squeezed, so that the inner wall of the four positioning arc blocks 9 is in close contact with the outer surface of the sliding cone block 12, and the second spring 18 is also in a state of being squeezed in the initial state;

[0073] In use, the corrugated pipe to be expanded is sleeved outside the four expansion strips 8, so that the lower surface of the corrugated pipe to be expanded is in contact with the upper surface of the four support plates 3. When the electric push rod 19 is started, the electric push rod 19 drives the sliding cone block 12 to move downward. The sliding cone block 12 synchronously gives the four positioning arc blocks 9 a pushing force away from each other during downward movement, so that the four positioning arc blocks 9 are all away from the center. During this process, the first spring 5 and the second spring 18 are further squeezed, so that the first spring 5 and the second spring 18 are further deformed. During this process, the corrugated pipe is expanded, thereby realizing the expansion work of the corrugated pipe, which is convenient and flexible to operate;

[0074] When the expansion of the corrugated pipe is completed, the electric push rod 19 is started to move upward, thereby giving the upper side and the lower side of the positioning arc block 9 a pushing force under the action of the release force of the first spring 5 and the second spring 18, pushing the positioning arc block 9 to move toward the center, thereby realizing the release of the expansion work of the corrugated pipe, which is high in working efficiency and flexible to operate.

The size and shape of the expansion strip 8 are different, and the size and shape of the installation arc plate 7, the fixed block 15, the installation rod 14, the connecting plate 16, the fixed spring 17 and the second spring 18 are unchanged. When the connecting plate 16 is pulled out, the connecting plate 16 drives the installation rod 14 to slide out of the corresponding positioning hole 13. At this time, the fixed spring 17 will be stretched. At this time, the installation arc plate 7 can be separated from the positioning arc block 9. At this time, the expansion strip 8 of different specifications can be replaced, thereby making the present scheme applicable to expansion strips 8 of different specifications, thereby increasing the practicality and applicability of the supporting and positioning mechanism, and improving the flexibility of the expansion of the corrugated pipe.

[0076] Working principle: when the device is used, through the initial state, the first spring 5 is in a state of being squeezed, so that the inner wall of the four positioning arc blocks 9 is in close contact with the outer surface of the sliding cone block 12, and the second spring 18 is also in a state of being squeezed in the initial state;

[0077] In use, the corrugated pipe to be expanded is sleeved outside the four expansion bars 8, so that the lower surface of the corrugated pipe to be expanded is in contact with the upper surface of the four support plates 3, when the electric push rod 19 is started, the electric push rod 19 drives the sliding cone block 12 to move downward, and the sliding cone block 12 synchronously gives the four positioning arc blocks 9 a pushing force away from each other during the downward movement, so that the four positioning arc blocks 9 are all away from the center, and the first spring 5 and the second spring 18 are further extruded during the process, so that the first spring 5 and the second spring 18 are further deformed, and the corrugated pipe is expanded during the process, thereby realizing the expansion work of the corrugated pipe, which is convenient and flexible to operate.

[0078] When the expansion of the corrugated pipe is completed, the electric push rod 19 is started to move upward, and then the upper side and the lower side of the positioning arc block 9 are given a pushing force under the action of the release force of the first spring 5 and the second spring 18, the positioning arc block 9 is pushed to move to the center, and then the expansion work of the corrugated pipe is released, which is high in working efficiency and flexible to operate.

[0079] Further, in the scheme, there are multiple sets of dismounting mechanisms of different specifications, wherein the sizes and shapes of the expansion bars 8 are different, and the sizes and shapes of the mounting arc plates 7, the fixed blocks 15, the mounting rods 14, the connecting plates 16, the fixed springs 17 and the second springs 18 are unchanged, when the connecting plate 16 is pulled out, the connecting plate 16 drives the mounting rod 14 to slide out of the corresponding positioning hole 13, at this time, the fixed spring 17 is stretched, at this time, the mounting arc plate 7 can be separated from the positioning arc block 9, at this time, the expansion bar 8 of different shapes and specifications can be replaced, thereby making the scheme applicable to the expansion bars 8 of different specifications, thereby increasing the practicality and applicability of the supporting and positioning mechanism, and improving the flexibility of the expansion of the corrugated pipe.
