It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0040] Reference Figures 1 to 9 The tool shown is for disassembling and assembling a switch machine anti-pinch device. It includes a special connector 18 with a cylindrical pin 2 at one end for insertion into the large screw plug hole 13 of the anti-pinch device 15. A square boss 3 is provided at the end of the special connector 18 away from the cylindrical pin 2. A special ratchet wrench 17 has a housing 4 at one end, inside which a ratchet gear 10 is housed. A square interface 5 is located at the center of the ratchet gear 10, penetrating the housing 4. The square interface 5 is used to engage with the square boss 3. A lever 8 is provided at the end of the special ratchet wrench 17 away from the housing 4 for rotating the ratchet gear 10.

[0041] In some specific embodiments, the dedicated connector 18 also includes a magnet 1, which is disposed on the side of the dedicated connector 18 away from the square boss 3 and is embedded in the dedicated connector 18.

[0042] In some specific embodiments, a strip-shaped hole is provided at one end of the housing 4 near the force-applying rod 8, and the strip-shaped hole extends longitudinally through the housing 4. A first screw hole is also provided on the housing 4, and the first screw hole extends transversely through the housing 4.

[0043] In some specific embodiments, a ratchet forward / reverse selector switch 6 is also included; it is disposed within the strip-shaped hole of the housing 4, with both ends of the ratchet forward / reverse selector switch 6 extending to the outside of the strip-shaped hole. A second screw hole is also provided at the center of the ratchet forward / reverse selector switch 6.

[0044] In some specific embodiments, the upper and lower ends of the ratchet forward / reverse changeover switch 6 are provided with teeth, which mesh with the ratchet gear 10.

[0045] In some specific embodiments, a screw 7 is also included, passing through the first screw hole and the second screw hole, for fixing the ratchet forward / reverse changeover switch 6; the ratchet forward / reverse changeover switch 6 can rotate on the screw 7.

[0046] In some specific embodiments, a ratchet cylindrical pin 11 and a ratchet spring 12 are also included;

[0047] The ratchet spring 12 is located at the end of the ratchet forward / reverse switch 6 away from the ratchet gear 10 and is fixedly connected to the inside of the housing 4;

[0048] The ratchet cylindrical pin 11 is located between the ratchet spring 12 and the ratchet forward / reverse changeover switch 6, with one end fixedly connected to the end of the ratchet spring 12 away from the force-applying rod 8;

[0049] The end of the ratchet cylindrical pin 11 away from the ratchet spring 12 abuts against the ratchet forward / reverse changeover switch 6.

[0050] In some specific embodiments, a rubber sleeve 9 is also included, which is fitted onto the force-adding rod 8 and has anti-slip threads.

[0051] In some specific embodiments, a large screw plug 16 is also included. The large screw plug 16 has a large screw plug through hole 13, and an external thread 14 is also provided along the circumference of the large screw plug 16.

[0052] The working method of this utility model:

[0053] When the switch machine needs maintenance and disassembly of the anti-pinch device 15, the end of the special connector 18 with the cylindrical pin 2 is aligned with the large plug 16, and the two cylindrical pins 2 are aligned with the through holes on the large plug 16. When the special connector 18 contacts the large plug 16, due to the magnetic force of the strong magnet 1 on the special connector 18, the special connector 18 is attracted to the large plug 16. Then, hold the lever 8 of the special ratchet wrench 17 and align the square interface 5 of the ratchet wrench head with the square boss 3 on the special connector 18. After locking in place, slowly rotate the ratchet wrench around the center of the square hole. The rotational force is transmitted from the ratchet wrench to the special connector 18, and then from the special connector 18 to the large plug 16 through the two cylindrical pins 2. The large plug 16 slowly unscrews out of the anti-pinch device 15 until it is removed. Due to the anti-reverse structure of the ratchet wrench, the large plug 16 can be removed in one locking action.

[0054] Similarly, after the anti-squeezing device 15 is repaired, the large plug 16 is first fixed to its original position by hand-tightening. Then, the special connector 18 is attached to the large plug 16. Press the direction change switch on the ratchet wrench to change the anti-reverse direction. Then, attach the ratchet wrench to the square boss 3 of the special connector 18. Then, slowly and forcefully rotate the ratchet wrench until the large plug 16 is tightened and fixed in place.

[0055] By adopting the above-disclosed technical solution of this utility model, the following beneficial effects are obtained:

[0056] This utility model discloses a tool for disassembling and assembling a switch machine anti-pinch device 15, comprising: a special connector 18, one end of which is provided with a cylindrical pin 2 for insertion into the large screw plug through hole 13 of the anti-pinch device 15; a square boss 3 is provided at the end of the special connector 18 away from the cylindrical pin 2; a special ratchet wrench 17, one end of which is provided with a housing 4, inside which a ratchet gear 10 is provided, and a square interface 5 is provided at the center of the ratchet gear 10, penetrating the housing 4; the square interface 5 is used to engage with the square boss 3; a force-applying rod 8 is provided at the end of the special ratchet wrench 17 away from the housing 4 for rotating the ratchet gear 10.
