Detailed Description
First embodiment, as shown in fig. 1-5, the present invention comprises a pen holder 1, a pen point 2 is detachably mounted at the bottom end of the pen holder 1, a fixed sleeve 3 is fixedly sleeved at the top end of the pen holder 1, a flexible tube 4 is movably sleeved at the top of the fixed sleeve 3, one end of the flexible tube 4 is fixedly communicated with a pressurizing ball 5, a movable connecting member 6 is fixedly mounted at the side surface of the fixed sleeve 3, a telescopic support rod 7 is fixedly mounted at the side surface of the movable connecting member 6, a pen core 8 is detachably mounted in the pen holder 1, an air bag 9 is fixedly sleeved at the top end of the pen core 8, an upper connecting tube 91 is integrally formed at the top end of the air bag 9, a lower connecting tube 92 is integrally formed at the bottom end of the air bag 9, a second air inlet assembly 93 is fixedly mounted at the bottom end of the upper connecting tube 91, the top end of the upper connecting tube 91 is fixedly communicated with the bottom end of the flexible tube 4, the bottom end of the lower connecting tube 92 is fixedly communicated with the top end of the pen core 8, a first air inlet assembly 10 is fixedly installed on the side surface of the pressure increasing ball 5, a fixed circular plate 101 is fixedly installed on one side inside the first air inlet assembly 10, a spring 102 is fixedly connected to the side surface of the fixed circular plate 101, a movable circular plate 103 is fixedly connected to the right end of the spring 102, a fixing plate 104 is fixedly installed on the other side inside the first air inlet assembly 10, and the side surface of the movable circular plate 103 is attached to the side surface of the fixing plate 104.
In the second embodiment, on the basis of the first embodiment, the inner wall of the telescopic supporting rod 7 is provided with a guide groove 71, the upper end and the lower end of the guide groove 71 are provided with rotating grooves 72, the inner wall of the telescopic supporting rod 7 is provided with a clamping groove 73, a movable rod 74 is movably mounted inside the telescopic supporting rod 7, a clamping block 75 is fixedly mounted on the side surface of the top end of the movable rod 74, a bottom pin 76 is fixedly mounted at the bottom end of the movable rod 74, and the size of the clamping block 75 is matched with that of the guide groove 71.
The working principle is as follows: the air bag 9 is arranged at the top end of the pen core 8, air with certain air pressure is pumped into the air bag 9, so that the pen core 8 can normally discharge ink in the inverted state, and the air in the air bag 9 is supplemented at any time through the arranged pressurizing ball 5; through the flexible bracing piece 7 of side-mounting at fixed sleeve 3, and thereby flexible bracing piece 7 is extendible as the bracing piece to the drawing circle can shorten and do not influence the use of plotting pen.
The first innovation point implementation step:
an air bag 9 is arranged at the top of the pen core 8, and the ink in the pen core 8 is pressed by air pressure in the air bag 9;
when the air pressure of the air bag 9 is insufficient, the pressurizing ball 5 is pressed to enable the air inside the pressurizing ball to enter the air bag 9 through the hose 4 and the second air inlet assembly 93, so that the pressure is provided; then the pressurizing ball 5 recovers to be spherical, and in the recovery process, gas enters the pressurizing ball 5 from the first air inlet assembly 10;
through the first air intake assembly 10, when gas is transported from the right to the left, other air intake assemblies can extrude the movable circular plate 103 to contract the spring 102, so that the gas enters through the fixed plate 104 and the movable circular plate 103, and when the gas is transported from the left to the right, the movable circular plate 103 can extrude the fixed plate 104, the gas cannot pass through, and similarly, the gas can only pass through the second air intake assembly 93 from the top to the bottom.
The implementation step of the second innovation point:
the first step is as follows: when the compasses are needed to be used, the movable rod 74 is lifted slightly upwards, and then the movable rod 74 is rotated ninety degrees, so that the clamping block 75 is matched with the guide groove 71;
the second step: the movable rod 74 is pulled downward;
the third step: finally, the movable rod 74 is rotated ninety degrees, so that the bottom end of the bottom needle 76 can be aligned with the center of a circle to perform circle drawing operation.
