When the round handle 32 is pressed, the third spring 33 is stretched, and the first extension column 35 and the second extension column 36 move toward the extension plate 3, so that the first pawl 23 and the second pawl 24 are separated from the surface of the positive ratchet 2. When the round handle 32 is released, the third spring 33 will return The second extension column 36 is released from the extension plate 3, and the operating disk 14 can rotate normally. By setting the first extension column 35 and the second extension column 36, the staff can choose whether to press the round handle 32 according to the actual situation, so that when the staff repairs heavier objects, the process of turning the objects is easier, which is convenient for the staff to use the equipment, and increases the practicality and convenience of the equipment. The position of the connecting rod 42 can be changed by pulling the slider 41. Through the provided slide groove 4 and the slider 41, when the equipment is working, when the staff needs to clearly observe the object being repaired, the connecting rod 42 can be moved to make the lamp 43 The device is closer to the operating panel 14, which is convenient for the staff to observe the items to be repaired, and reduces the phenomenon that the staff cannot observe the items to be repaired due to the light source being too far away, thereby increasing the practicality of the equipment and facilitating the staff to use the equipment.
