[0002] Circuit breakers are crucial devices in power systems, used to control and protect circuits. To ensure safe operation, circuit breakers are typically equipped with cotter pins as a locking mechanism to prevent accidental closing under non-preset conditions. However, during regular maintenance or repairs, operators need to frequently remove the cotter pins, a process that is both tedious and inefficient. To address this, a circuit breaker cotter pin remover was designed. This remover simplifies the steps for removing cotter pins, saving operators time when using the device. Existing circuit breaker cotter pin removers use a threaded connection to install the remover body inside the handle. After prolonged use, this method can lead to loosening between the remover body and the handle, causing them to separate and reducing the safety of operators when using the equipment.

[0012] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0013] Example 1
[0014] This utility model provides a circuit breaker cotter pin remover, such as... Figures 1 to 5 As shown, the device includes: a remover body 1, a handle 2, and a connecting assembly. The remover body 1 is made of carbon steel, and the handle 2 is made of PVC. The surface of the handle 2 has anti-slip texture (existing technology). The remover body 1 is connected to the handle 2. The connecting assembly includes a threaded part 3, a hexagonal protrusion 4, a moving block 5, a limiting rod 6, and a positioning sleeve 7. The threaded part 3 is a bolt. The hexagonal protrusion 4 is connected to the remover body 1 through the threaded part 3. The remover body 1 is connected to the handle 2 through the threaded part 3. One end of the limiting rod 6 is connected to the positioning sleeve 7, and the other end of the limiting rod 6 is connected to the handle 2. The moving block 5 slides inside the handle 2 and on the outer surfaces of the hexagonal protrusion 4 and the limiting rod 6. There are four limiting rods 6, which are arranged in a circular array on the bottom surface of the positioning sleeve 7 to restrict the moving block 5 during movement. The moving block 5 has a hexagonal groove inside that meshes with the hexagonal protrusion 4 to restrict the rotation of the hexagonal protrusion 4.
[0015] By restricting the hexagonal protrusion 4 by moving block 5, the remover body 1 installed inside handle 2 cannot be removed, thereby avoiding the problem of the remover body 1 installed inside handle 2 separating from handle 2, thus improving the stability and safety of the device during use.
[0016] When in use, if the operator needs to install the remover body 1 inside the handle 2, first insert the end of the remover body 1 with the threaded part 3 into the handle 2, and rotate the remover body 1. This causes the remover body 1 to drive the threaded part 3 to rotate along the threaded groove inside the handle 2, gradually moving it inwards. As the threaded part 3 moves, it drives the hexagonal protrusion 4 and the remover body 1 to move synchronously. When one end face of the hexagonal protrusion 4 is in contact with the surface of the moving block 5, the hexagonal protrusion 4 continues to move, driving the moving block 5 to move synchronously. As the moving block 5 moves, it simultaneously moves along the outer surface of the four limiting rods 6 towards the positioning sleeve 7, and the four limiting rods 6 restrict the moving block 5, making its movement more stable. The movement of the moving block 5 will cause the elastic element... 9. The hexagonal protrusion 4 is compressed and deformed, and rotates along the surface of the moving block 5. When the hexagonal protrusion 4 and the hexagonal groove inside the moving block 5 are engaged with each other, the hexagonal protrusion 4 cannot limit the elastic element 9 through the moving block 5, causing the elastic element 9 to rebound and push the moving block 5 to move in the opposite direction. When the moving block 5 moves, it moves along the outer surface of the hexagonal protrusion 4. At this time, through the cooperation between the moving block 5 and the hexagonal protrusion 4, the remover body 1 cannot continue to rotate, thereby completing the process of installing the remover body 1 inside the handle 2. By restricting the hexagonal protrusion 4 through the moving block 5, the remover body 1 installed inside the handle 2 cannot be removed, thereby avoiding the problem of the remover body 1 installed inside the handle 2 separating from the handle 2, thus improving the stability and safety of the device during use.
[0017] Specifically, a threaded part 3 is fixedly connected to one end face of the remover body 1. The remover body 1 is threaded to the inside of the handle 2 through the threaded part 3. A hexagonal protrusion 4 is fixedly connected to the end of the threaded part 3 away from the remover body 1. A movable block 5 is snapped onto the outer surface of the hexagonal protrusion 4. Four limiting rods 6 are slidably connected inside the movable block 5. The four limiting rods 6 are arranged in a circumferential array around the outer surface of the movable block 5. One end of each of the four limiting rods 6 is fixed inside the handle 2, and the other end of each of the four limiting rods 6 is fixed onto the positioning sleeve 7. The positioning sleeve 7 is snapped onto the inside of the remover body 1.
[0018] To achieve the separation of the pick-up device body 1 and handle 2 in the above example, the following solution is proposed: Figures 2 to 4As shown, it also includes a separation component, which includes a threaded part 8, an elastic part 9, a connecting groove 10, and a movable part 11. The threaded part 8 has an internal mounting groove, which is rectangular. A hexagonal wrench is fitted inside the mounting groove. When the hexagonal wrench drives the movable part 11 and the threaded part 8 to rotate, the connecting groove 10 does not affect the hexagonal wrench during the rotation. The elastic part 9 is a spring. The movable part 11 is sleeved inside the positioning sleeve 7. The threaded part 8 is connected to the movable part 11. One end of the elastic part 9 is connected to the movable part 11, and the other end of the elastic part 9 is connected to the movable block 5. The handle 2 has an internal connecting groove 10. The outer surface of the movable part 11 fits against the inner wall of the positioning sleeve 7 to limit the movement of the movable part 11 inside the positioning sleeve 7. The movable part 11 has internal threads, and the threaded part 8 is engaged with these internal threads.
[0019] The engagement of threaded part 2 8 and moving part 11 allows the hexagonal protrusion 4 and moving block 5 to separate, avoiding the problem that the remover body 1 cannot be separated after being installed inside the handle 2, thereby improving the safety when separating the remover body 1 and handle 2.
[0020] When in use, if the operator needs to separate the remover body 1 from the handle 2, a hex wrench is installed inside the mounting groove of the threaded part 2 8. The operator then uses the hex wrench to rotate the threaded part 2 8. As the threaded part 2 8 rotates, it rotates along the internal thread of the moving part 11, causing the moving part 11 to slide inside the positioning sleeve 7. At this time, the positioning sleeve 7 restricts the moving part 11, making the movement of the moving part 11 more stable. When the moving part 11 moves, the elastic part 9 pulls the moving block 5 to move synchronously. When the moving block 5 moves, it moves along the outer surface of the hexagonal protrusion 4 until the hexagonal protrusion 4 and the moving block 5 separate. At this time, since the restriction of the moving block 5 on the hexagonal protrusion 4 is released, when the operator rotates the remover body 1 in the opposite direction, the remover body 1 separates from the handle 2. Through the cooperation of the threaded part 2 8 and the moving part 11, the hexagonal protrusion 4 and the moving block 5 are separated, avoiding the problem that the remover body 1 cannot be separated after being installed inside the handle 2, thereby improving the safety when separating the remover body 1 from the handle 2.
[0021] Specifically, one end of the movable block 5 is fixedly connected to an elastic element 9, and the other end of the elastic element 9 is fixedly connected to the movable element 11. The movable element 11 slides inside the positioning sleeve 7. The movable element 11 is threadedly connected to a threaded element 8. The threaded element 8 rotates inside the handle 2. The handle 2 has a connecting groove 10 inside, and the threaded element 8 has an installation groove inside. The installation groove is vertically aligned with the connecting groove 10.
[0022] Working Principle: When using this device, if the operator needs to install the remover body 1 inside the handle 2, first insert one end of the remover body 1 with the threaded part 3 into the handle 2, and rotate the remover body 1. This causes the remover body 1 to drive the threaded part 3 to rotate along the threaded groove inside the handle 2, gradually moving it inward. As the threaded part 3 moves, it drives the hexagonal protrusion 4 and the remover body 1 to move synchronously. When one end face of the hexagonal protrusion 4 is in contact with the surface of the moving block 5, the hexagonal protrusion 4 continues to move, driving the moving block 5 to move synchronously. As the moving block 5 moves, it simultaneously moves along the outer surface of the four limiting rods 6 towards the positioning sleeve 7, and the four limiting rods 6 restrict the moving block 5, making the movement of the moving block 5 more stable. The movement of the moving block 5 compresses and deforms the elastic element 9, causing it to rotate along the surface of the moving block 5. When the hexagonal protrusion 4 and the hexagonal groove inside the moving block 5 are engaged, the hexagonal protrusion... Block 4 cannot limit the elastic element 9 by the movable block 5, causing the elastic element 9 to rebound and push the movable block 5 to move in the opposite direction. When the movable block 5 moves, it moves along the outer surface of the hexagonal protrusion 4 (at this time, the operator rotates the threaded part 8. When the threaded part 8 rotates, it rotates along the internal thread of the movable part 11 and drives the movable part 11 to move towards the hexagonal protrusion 4. When the movable part 11 moves, it pushes the movable block 5 to move synchronously through the elastic element 9, so that the movable block 5 completely wraps the hexagonal protrusion 4). At this time, through the cooperation between the movable block 5 and the hexagonal protrusion 4, the remover body 1 cannot continue to rotate, thus completing the process of installing the remover body 1 inside the handle 2. By restricting the hexagonal protrusion 4 by the movable block 5, the remover body 1 installed inside the handle 2 cannot be removed, thereby avoiding the problem of the remover body 1 installed inside the handle 2 separating from the handle 2, thus improving the stability and safety of the device during use. When the operator needs to separate the remover body 1 from the handle 2, a hex wrench is installed inside the mounting groove of the threaded part 2 8. The operator then uses the hex wrench to rotate the threaded part 2 8. As the threaded part 2 8 rotates, it rotates along the internal thread of the moving part 11, causing the moving part 11 to slide inside the positioning sleeve 7. At this time, the positioning sleeve 7 restricts the moving part 11, making the movement of the moving part 11 more stable. When the moving part 11 moves, the elastic part 9 pulls the moving block 5 to move synchronously. When the moving block 5 moves, it moves along the outer surface of the hexagonal protrusion 4 until the hexagonal protrusion 4 and the moving block 5 separate. At this time, since the restriction of the moving block 5 on the hexagonal protrusion 4 is released, when the operator rotates the remover body 1 in the opposite direction, the remover body 1 separates from the handle 2. Through the cooperation of the threaded part 2 8 and the moving part 11, the hexagonal protrusion 4 and the moving block 5 are separated, avoiding the problem that the remover body 1 cannot be separated after being installed inside the handle 2, thereby improving the safety when separating the remover body 1 from the handle 2.
[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
