[0038] Specifically, the working principle of the automatic rotating pencil is as follows: when using the pencil, first check whether the structure of the pencil is intact. After ensuring that the structure is intact, put it into use. The pen case 100 is lifted to make the rotating assembly 400 slide down under the weight, and drive the second protruding teeth 4003 on both sides of the ring 4002 to move, so as to separate the first protruding teeth 3008 on the first sleeve 3001 from the second protruding teeth 4003. At the same time, the second protruding teeth 4003 on the other side of the ring 4002 are pressed against the first protruding teeth 3008 of the second sleeve 3002, and the teeth are adjusted, and the rotating assembly 400 is driven to rotate in a certain angle as a whole, so as to cause the lead head 3004 to follow the round rod 400. 1 is rotated, and when the pen is put down again, the round rod 4001 is squeezed upward, so that the second convex tooth 4003 is again fitted with the first convex tooth 3008 on the first sleeve 3001, and the teeth are rotated in the same direction, so that the lead head 3004 is rotated. Secondly, through the connection and use of the limit sleeve 5002, the counterweight rod 500 and the rotating component 400 are connected, so that the counterweight rod 500 presses the rotating component 400 downward, which is convenient for increasing the activity speed of the rotating component 400. The installation and use of the rubber pad block 5003 is conducive to reducing the impact and shaking caused by the reciprocating movement of the limit sleeve 5002. At the same time, the setting of the sliding ring groove 1002 makes the grip of the pencil more stable.
[0039] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
