Embodiment 1
[0051] Refer to attached figure 1 As shown, the present embodiment mainly discusses how to realize the opening of the movable plate 4 in the whole pen structure, specifically:
[0052] A pen, comprising a penholder 1 and a refill 101 arranged on the penholder 1, a sleeve 2 and a rotating cylinder 3 are sequentially sleeved on the outside of the penholder 1, and the rotating cylinder 3 is rotatably connected to the sleeve 2;
[0053] Refer to attached figure 2 and attached Figure 8 As shown, the sleeve 2 and the drum 3 are respectively provided with a first perforation 201 and a second perforation 301. The positions of the first perforation 201 and the second perforation 301 correspond to each other. When the drum 3 rotates, it drives the penholder 1 to move, so that The refill 101 passes through the first hole 201 and the second hole 301, and is exposed on the top of the drum 3 or hidden in the sleeve 2;
[0054] A movable plate 4 is provided between the sleeve 2 and the ...
Embodiment 2
[0060] On the basis of Embodiment 1, this embodiment describes the specific structure of the movable plate 4 .
[0061] Specifically, refer to the attached Figure 2-4 As shown, there are several first sliding slots 302 , and the several first sliding slots 302 are arranged along the outer periphery of the second through hole 301 , specifically on the inner wall, and each first sliding slot 302 is correspondingly provided with a movable plate 4 . There are a plurality of movable plates 4, which are arranged corresponding to the first chute 302, so that it is convenient to be arranged as a structure such as an arc with sharp corners, and a plurality of sharp corners are combined to form a circular structure, so as to realize the shielding of the first perforation 201, and then the pen The core 101 cannot be exposed through the first through hole 201 . Specifically, when rotating, a plurality of movable plates 4 move toward the top of the first perforation 201 at the same time,...
Embodiment 3
[0065] In this embodiment, the description mainly focuses on the limitation in the movement of the movable plate 4 .
[0066] Refer to attached Figure 5-7 As shown, further, the other side of the movable plate 4 is provided with a limit block 402, through the attachment Figure 8-10 As shown, the outer wall of the sleeve 2 is provided with a limiting slot 202 for the movement of the limiting block 402, specifically, the limiting block 402 is a cylindrical structure. By setting the limit block 402 and the limit groove 202, when the slider 401 slips or the first chute 302 fails to cause the slider 401 to derail, it can play a limiting role, and at the same time, it can realize the movement of the entire movable plate 4. Activity. Refer to attached Figure 5-7 As shown, for the movable plate 4, the limit block 402 is set on the other side, so that the two sides of the movable plate are respectively provided with convex structures to increase its strength. If they are arranged...
