[0002] A pen holder is a container used to store pens and other stationery. To facilitate finding pens, rotating pen holders have emerged on the market; a simple turn allows you to locate the desired pen. For example, Chinese utility model CN223302441U discloses a rotating pen holder where the holder frame is rotatably positioned on top of a base, and the holder body is mounted on the frame. Additionally, drawers are located at the bottom of each pen body, allowing for the storage of small items such as erasers, thus improving space utilization. While the holder body has multiple drawers, current designs require opening each drawer sequentially to find items. If all drawers could be opened simultaneously, it would save time.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 6As shown, a rotating pen holder includes a base 1 and a cylinder assembly. The cylinder assembly includes a cylinder 2, a turntable 3, and three drawers 4. The lower end of the turntable 3 is rotatably connected to the upper end of the base 1. A connecting shaft 31 is provided between the upper end of the turntable 3 and the lower end of the cylinder 2. The number of connecting shafts 31 corresponds to the number of drawers 4. A receiving cavity 20 is formed between the turntable 3 and the cylinder 2. The drawers 4 are located in the receiving cavity 20. One end of the drawer 4 is rotatably connected to the connecting shaft 31, and the other end of the drawer 4 can rotate into or out of the receiving cavity 20. A connecting rod assembly is provided between each drawer 4. The connecting rod assembly includes a transmission rod 51 and a lever 52 corresponding to the number of drawers 4. One end of the lever 52 is connected to the transmission rod 51. The drawer 4 is provided with a mating part 41 connected to the other end of the lever 52. The cylinder 2 is provided with a drive rod 6 connected to the transmission rod 51. When the drive rod 6 is activated, the transmission rod 51 is driven to drive the lever 52, and the lever 52 causes each drawer 4 to rotate.

[0021] The upper surface of the turntable 3 has a receiving groove 30. The transmission rod 51 is vertically positioned at the center of the receiving groove 30. The lever 52 is located below the drawer 4. The lower surface of the mating part 41 has a mating groove 410. One end of the mating groove 410 has a notch 411. The other end of the lever 52 passes through the notch 411 and is located inside the mating groove 410. The bottom center of the cylinder 2 has a first through hole 201. The upper end of the transmission rod 51 passes through the first through hole 201 and is connected to the drive rod 6. The drive rod 6 is located inside the cylinder 2. The lever 52 is located inside the receiving groove 30. When the drive rod 6 is rotated, the transmission rod 51 rotates accordingly. The lever 52 rotates around the transmission rod 51, causing the drawer 4 to rotate.

[0022] The other end of the lever 52 is provided with an enlarged portion 521, and an indentation 522 is formed between one end of the lever 52 and the enlarged portion 521. The enlarged portion 521 is located within the mating groove 410. The enlarged portion 521 can prevent the other end of the lever 52 from disengaging from the mating groove 410. After the lever 52 rotates, the indentation 522 abuts against one end of the notch 411, that is, against the end of the groove wall of the mating groove 410. After the lever 52 continues to rotate, it drives the mating portion 41.

[0023] The cylinder body 2 has a cylindrical partition 21 inside, and the drive rod 6 is located within the space enclosed by the cylindrical partition 21. The upper end of the drive rod 6 is higher than the cylindrical partition 21, and the outer wall of the upper end of the drive rod 6 has an anti-slip groove 61. The center of the drive rod 6 has a groove 60. The upper end of the drive rod 6 is higher than the cylindrical partition 21 and has an anti-slip groove 61 to facilitate the operation of the drive rod 6. The groove 60 can be used to store pens.

[0024] The transmission rod 51 has a convex shaft 511 at its upper end, and a guide rib 512 on the outer wall of the convex shaft 511. The lower end face of the drive rod 6 has a slot 62 that engages with the convex shaft 511, and the inner wall of the slot 62 has a guide groove 621 that slides with the guide rib 512. The lower end face of the drive rod 6 has a limiting convex ball 63, and the upper end face of the bottom of the cylinder 2 has several limiting holes 22. The slot 62 is circumferentially limited and axially slides with the convex shaft 511. Rotating the drive rod 6 can drive the transmission rod 51 to rotate. The limiting holes 22 are arranged circumferentially with the first through hole 201 as the center. The limiting holes 22 can engage with the limiting convex ball 63 on the rotation path of the limiting convex ball 63 for positioning after the drawer 4 is opened. When opening or closing the drawer 4, the drive rod 6 is pulled upward, the convex shaft 511 slides axially with the slot 62, the limiting convex ball 63 disengages from the limiting hole 22, and then the drive rod 6 can be rotated.

[0025] The transmission rod 51 has a hollow structure. A second through hole 513 is provided on the top surface of the convex shaft 511. A connecting post 622 protrudes from the bottom of the slot 62. The connecting post 622 passes through the second through hole 513 and is located inside the convex shaft 511. A spring 64 is sleeved around the outer circumference of the connecting post 622. A limiting member 65 is provided at the lower end of the connecting post 622. The spring 64 rests between the inner wall of the top of the convex shaft 511 and the limiting member 64. The limiting member 64 is a screw, screwed to the bottom of the connecting post 622, with the lower end of the spring 64 resting against the screw head. This configuration ensures that the drive rod 6 maintains a downward resetting trend, allowing it to quickly approach the bottom surface of the cylinder 2, and also keeping the lower end of the drive rod 6 close to the bottom surface of the cylinder 2.

[0026] The lower end face of the turntable 3 has a protruding rotating shaft 32, the upper end face of the base 1 has a shaft hole 10, the rotating shaft 32 is inserted into the shaft hole 10, and the upper end face of the base 1 has a bearing 11 connected to the lower end face of the turntable 3.

[0027] This utility model's rotating pen holder features multiple rotatably connected drawers 4, which can be simultaneously rotated via a linkage assembly. In use, gently lifting the drive rod 6 disengages the limiting protrusion 63 from the limiting hole 22. Rotating the drive rod 6 causes the transmission rod 51 to rotate, which in turn rotates the lever 52. After rotating to a certain angle, the inner recess 522 of the lever 52 abuts against the end of the mating groove 410. Continued rotation of the lever 52 drives the mating part 41, causing the drawers 4 to slide. The drawers 4 can be opened or closed by rotating the drive rod 6 clockwise or counterclockwise. This rotating pen holder allows all drawers to be opened or closed simultaneously, saving time and making it convenient to use.
