A first rotating shaft 1102 is rotatably connected to the inner circle of the convex frame 1101. Connecting plates 1103 are fixedly connected to the front and rear sides of the first rotating shaft 1102. A second rotating shaft 1104 is fixedly connected to the bottom of the inner side of the connecting plate 1103. The clamping component 12 includes a sleeve 1201.

[0031] Furthermore: The sleeve 1201 is connected to the puller main body 3 through the connecting component 11, making the movement range of the sleeve 1201 more flexible. When the device is in use, the clamping protrusion 1203 can be used at more variable angles to clamp the internal structure of the high-voltage motor, facilitating the use by the staff. At the same time, the clamping protrusions 1203 are arranged at the bottoms of the inner and outer sides of the pulling arm 1202, enabling the device to position the structure from both the inner and outer sides during use, increasing the applicability of the device during use.

[0032] Embodiment 2

[0033] Refer to Figure 1 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 , and on the basis of Embodiment 1, it is further obtained that the limiting mechanism 2 includes a support component 21, a twisting component 22, and a positioning component 23. The support component 21 is arranged on the top of the puller main body 3. The twisting component 22 is arranged inside the support component 21. The positioning component 23 is arranged on the outer circle of the twisting component 22.

[0034] The support assembly 21 includes a fixing frame 2101 which is fixedly connected to the top of the puller main body 3 at a position inside the pull arm 1202. At the inner top of the fixing frame 2101, a fixing shaft 2102 is fixedly connected. An outer ring of the fixing shaft 2102 is rotatably connected with a rotating frame 2103. At the top of the rotating frame 2103, a fixing cylinder 2104 is fixedly connected. The twisting assembly 22 includes a threaded cylinder 2201 which is fixedly connected to the inside of the fixing cylinder 2104. An inner ring of the threaded cylinder 2201 is rotatably connected with a threaded rotating shaft 2202. At the inner side of the threaded rotating shaft 2202, a twisting disc 2203 is fixedly connected. The positioning assembly 23 includes a hexagonal threaded pipe 2301 which is threadedly connected to the outer ring of the threaded rotating shaft 2202. The hexagonal threaded pipe 2301 is slidably connected to the inside of the outer side of the fixing cylinder 2104. An outer ring of the hexagonal threaded pipe 2301 is fixedly connected with a limiting sliding piece 2302. The limiting sliding piece 2302 is slidably connected to the inner ring of the fixing cylinder 2104. At the outer side of the hexagonal threaded pipe 2301, a cushion block 2303 is fixedly connected.

[0035] Further: After the pull arm 1202 completes the positioning of the component through the cooperation of the clamping protrusion 1203 and the puller main body 3, the staff can adjust a plurality of cushion blocks 2303 to make the cushion blocks 2303 fit with the inner side of the pull arm 1202 to complete the positioning of the pull arm 1202, so that the pull arm 1202 will not turn over and disengage during the use of the device, increasing the stability of the device during use.

[0036] During the actual operation process, when this device is in use and the puller is needed to disassemble the high-voltage motor, the staff first clamp the pull arm 1202 located on the outer ring of the puller main body 3 at the bottom of the outer ring or the inner ring of the disc to be disassembled. Then the staff make the bottom of the puller main body 3 fit with the top axis center of the disc. Then rotate the inner turntable of the puller main body 3 to tighten the pull arm 1202 with the puller main body 3. Then the staff turn over the fixing cylinder 2104 and rotate the twisting disc 2203. The rotation of the twisting disc 2203 drives the rotation of the threaded rotating shaft 2202. The rotation of the threaded rotating shaft 2202 drives the hexagonal threaded pipe 2301 to move outwards. The outward movement of the hexagonal threaded pipe 2301 drives the cushion block 2303 to move outwards. The outward movement of the cushion block 2303 fits with the inner side of the pull arm 1202. At this time, the positioning process of the pull arm 1202 is completed, so that the pull arm 1202 cannot be misaligned and turned inwards under the tightened state, ensuring the stability of the pull arm 1202 during the use process. Then the staff continue to rotate the inner turntable of the puller main body 3, and can pull the part outwards through the pull arm 1202 and the clamping protrusion 1203 to complete the disassembly.
