Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Example 1
A chalk clip convenient for drawing a circle is shown in figures 1-6 and comprises a pen cap 1, a movable opening 2, a holder 3, a fixing ring 5, a spring 6 and a drawing mechanism, wherein the movable opening 2 is formed in the top of the pen cap 1, the holder 3 is connected to the inside of the pen cap 1 in a sliding mode, a first placing opening 4 is formed in the holder 3, the fixing ring 5 is connected to the lower portion of the inside of the pen cap 1, the spring 6 is connected between the upper portion of the fixing ring 5 and the holder 3, and the drawing mechanism is connected to the front side of the middle of the pen cap 1.
Drawing mechanism is including pivot 8, connecting rod 9, the movable rod 10, bolt 11, slider 12, a protection section of thick bamboo 13 and first magnet 14, open 1 middle part front side of pen socket has the second to place mouthful 7, the upper portion rotary type of 1 middle part front side of pen socket is connected with pivot 8, 8 middle parts of pivot are connected with connecting rod 9, connecting rod 9 middle part downside slidingtype is connected with movable rod 10, connecting rod 9 lower part front side thread type is connected with bolt 11, 1 upper portion outside rotary type of pen socket is connected with slider 12, the slider 12 middle part outside is connected with a protection section of thick bamboo 13, protection section of thick bamboo 13 middle part is connected with three first magnet 14 along circumference.
Still including protection mechanism, protection mechanism is including sheltering from lid 15, second magnet 17 and third magnet 18, and the inside downside sliding type of a protection section of thick bamboo 13 is connected with shelters from lid 15, shelters from 15 top openings and has the third to place mouthful 16, shelters from the lid 15 middle part left and right sides and all is connected with second magnet 17, and the 1 lower part left and right sides of pen cover all is connected with third magnet 18, third magnet 18 and the cooperation of second magnet 17.
When people need to use the chalk clip, firstly, the shielding cover 15 is manually grabbed and moved downwards manually, so that the pen cap 1 is opened, then the holder 3 is manually pressed, the holder 3 moves downwards to compress the spring 6, then, chalk is manually squeezed into the lower side of the holder 3 manually, the holder 3 is propped open, then the holder 3 is loosened, the spring 6 is reset to drive the holder 3 to reset upwards, the holder 3 resets upwards to clamp the chalk, when people need to draw a circle, the connecting rod 9 is manually grabbed and rotated forwards, the connecting rod 9 rotates forwards to drive the movable rod 10 to rotate forwards, then, the movable rod 10 is fixed with one point of the blackboard, then, the holder 3 is grabbed by taking the movable rod 10 as the center to rotate for one circle, so that the chalk is driven to rotate around the movable rod 10 for one circle, the effect of drawing the circle is achieved, when people need to adjust the length of the movable rod 10, the bolt 11 is manually rotated, so that the limit of the bolt 11 on the movable rod 10 is cancelled, then the length of the movable rod 10 is manually adjusted, then the bolt 11 is rotated and reset manually, so that the movable rod 10 is limited continuously, when people do not need to draw a circle, the protection cylinder 13 can be rotated manually, thereby leading the protective cylinder 13 to shield the connecting rod 9 and the movable rod 10, preventing the connecting rod 9 and the movable rod 10 from rotating and falling out, when people do not need to use the chalk clip, the lower side of the pen cap 1 is covered by manually grasping the shielding cover 15, thereby protecting the remaining chalk, preventing the shielding cover 15 from falling out by the second magnet 17 and the third magnet 18 attracting each other, then the chalk clip is placed on one side of the magnetic blackboard, and the chalk clip is fixed on the magnetic blackboard through the magnetic force of the first magnet 14, so that people can conveniently take the chalk clip.
