Specific implementation mode
As shown in Figs. 1-3, the utility model includes box body 1 and chalk outlet 2, which is characterized in that the top of the box body 1
The limiting slot 3 in centre position is run through by axis 4, and the bottom for pressing axis 4 is connect with the centre position of supporting rod 5, the support
The both ends of bar 5 are symmetrically arranged with identical connecting rod 6, and the bottom of the connecting rod 6 is connect with the side wall of supporting plate 7, the supporting plate
7 bottom is provided through the support plate 8 of 1 inner lower of box body, and elastic device 9, institute are additionally provided on the side wall of the box body 1
The top both sides for stating support plate 8 are symmetrically arranged with tilted block 10.
The top of the supporting plate 7 is provided with for the bottommost of arcwall face and arcwall face and places groove 11, the placement groove
11 is corresponding with the chalk outlet 2 of 1 side wall of box body.
The bottom of the supporting plate 7 is connect by spring I 12 with the top of support plate 8.
The elastic device 9 include through 1 side wall of box body pull rod 901 and be sleeved on the outside of pull rod 901 and one end and box
The spring II 902 of 1 inner wall of body connection.
With the above arrangement, when the utility model is used, first by axis 4 is pressed, supporting rod 5, connecting rod are driven by axis 4
6 and supporting plate 7 move down, since the top both sides of support plate 8 are provided with tilted block 10, thus the chalk on 10 top of tilted block be incline
It tiltedly places, so when the top of supporting plate 7 moves down into the bottom margin of tilted-putted chalk, chalk can roll down to supporting plate first
On, chalk will be rolled down to by the inside of supporting plate 7 later places in groove 11, and then unclamps and press axis 4, and powder is driven by 4 return of axis
The pen front position that moves up and return to, unclamps after dropping pull rod 901 outward later, one end of pull rod 901 will collide place it is recessed
Chalk in slot makes chalk be popped up by chalk outlet 2.
