The user can also open the folder quickly and easily with his feet, making it more convenient to use.

[0014] When the user steps down on the locking end of the foot pedal, the foot pedal drives the first rotating shaft to rotate the rotating device. At the same time, the large shaft of the stepped shaft slides along the circumference of the first rotating shaft in the first keyway. The rotating device drives the slider to slide toward the upper joint and the lower joint, thereby locking the upper joint and the lower joint. At this time, the first rotating shaft just rotates to align with the large shaft of the stepped shaft in the second keyway. The large shaft of the stepped shaft is embedded in the second keyway under the rebound force of the elastic component. The stepped shaft re-locks the first rotating shaft and the first rotating shaft stops rotating. At this time, the upper joint and the lower joint are locked by the slider, and the folder is in a locked state. The user can also lock the folder quickly and easily with their feet, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Please refer to Figure 1 、 Figure 4 and Figure 10The two ends of the pedal 7 are a locking end 71 and an opening end 72 , respectively. The locking end 71 and the opening end 72 are relatively located on both sides of the first rotating shaft 8 . When the user steps on the locking end 71 of the foot pedal 7 with his foot, the foot pedal 7 drives the first rotating shaft 8 to rotate on the base 41, the first rotating shaft 8 drives the second gear 433 to rotate, the second gear 433 drives the first gear 432 to rotate, the first gear 432 drives the second rotating shaft 431 to rotate on the base 41, the second rotating shaft 431 drives the eccentric wheel 434 to rotate, the eccentric wheel 434 drives the two pull rings 436 to rotate toward the side of the first shaft pin 3, the two pull rings 436 drive the connecting rod 42 to move toward the side of the first shaft pin 3, and the connecting rod 42 drives the slider 6 to slide in the direction close to the upper joint 1 and the lower joint 2, the first clamping platform 61 and the second clamping platform 62 on the slider 6 are respectively embedded in the first clamping groove 12 and the second clamping groove 22. At this time, the slider 6 simultaneously clamps the upper joint 1 and the lower joint 2, so that the upper joint 1 and the lower joint 2 are locked together through the slider 6, and the folder is in a locked state.

[0033] When the user steps on the open end 72 of the foot pedal 7 with his foot, the foot pedal 7 drives the first rotating shaft 8 to rotate on the base 41, the first rotating shaft 8 drives the second gear 433 to rotate, the second gear 433 drives the first gear 432 to rotate, the first gear 432 drives the second rotating shaft 431 to rotate on the base 41, the second rotating shaft 431 drives the eccentric wheel 434 to rotate, the eccentric wheel 434 drives the two pull rings 436 to rotate to the side away from the first shaft pin 3, the two pull rings 436 drive the connecting rod 42 to move to the side away from the first shaft pin 3, the connecting rod 42 drives the slider 6 to slide in the direction away from the upper joint 1 and the lower joint 2, the first card platform 61 and the second card platform 62 on the slider 6 are respectively moved out of the first card slot 12 and the second card slot 22. At this time, the lock of the slider 6 and the upper joint 1 and the lower joint 2 is released, the upper joint 1 and the lower joint 2 are opened, and the folder is in the open state.

[0034] Please refer to Figure 1 、 Figure 3 、 Figures 6 to 9The locking device 5 includes a pedal rod 51, a stepped shaft 52, and a compression spring 53. A seventh groove 511 is defined at one end of the pedal rod 51. The seventh groove 511 is a through groove. The pedal rod 51 is rotatably connected to the upper joint 1 and is located above the open end 72 of the foot pedal 7. A stepped hole 15 is defined at the bottom of the third groove 14 of the upper joint 1 for mating with the stepped shaft 52. The large shaft 521 of the stepped shaft 52 is located within the large hole 151 of the stepped hole 15. The compression spring 53 is sleeved on the small shaft 522 of the stepped shaft 52. The small shaft 522 of the stepped shaft 52 passes through the large hole 151 and the small hole 152 of the stepped hole 15 in sequence, and is then hingedly connected to the pedal rod 51. The small shaft 522 of the stepped shaft 52 is located within the seventh groove 511. The compression spring 53 is located in the large hole 151 of the stepped hole 15 , and the compression spring 53 presses against the end surface of the large shaft 521 of the stepped shaft 52 .

[0035] Please refer to Figure 1 、 Figure 4 and Figure 9 A first keyway 81 in the shape of a racetrack is formed on the circumferential surface of the first rotating shaft 8. A second keyway 82 is formed at the bottom of one end of the first keyway 81. The second keyway 82 mates with the main shaft 521 of the shaft 52. When the upper joint 1 and the lower joint 2 are fastened together, the stepped hole 15 corresponds to the first keyway 81.

[0036] Please refer to Figure 1 、 Figures 6 to 9 When the user steps on the pedal rod 51, the pedal rod 51 rotates around the upper joint 1 and drives the stepped shaft 52 to move along the stepped hole 15 in the direction away from the first rotating shaft 8. The large shaft 521 of the stepped shaft 52 moves toward the small hole 152 of the stepped hole 15 and compresses the compression spring 53. When the large shaft 521 of the stepped shaft 52 moves out of the second key groove 82, the locking of the stepped shaft 52 on the first rotating shaft 8 is released. The user continues to step down to the open end 72 of the foot pedal 7, and the foot pedal 7 drives the first rotating shaft 8 It rotates on the base 41, thereby releasing the lock between the slider 6 and the upper joint 1 and the lower joint 2. When the user's foot is released, the large shaft 521 of the stepped shaft 52 is stuck in the first key groove 81 under the action of the rebound force of the compression spring 53. At the same time, although the rebound force of the compression spring 53 is not completely released, due to the rotation of the first rotating shaft 8, the alignment of the second key groove 82 and the stepped hole 15 is offset, and the large shaft 521 of the stepped shaft 52 cannot be embedded in the second key groove 82, so that the folder can be opened quickly and conveniently.

[0037] When the folder needs to be locked, the user steps on the locking end 71 of the foot pedal 7 with his foot, and the foot pedal 7 drives the first rotating shaft 8 to rotate on the base 41. The large shaft 521 of the stepped shaft 52 slides along the circumference of the first rotating shaft 8 in the first key groove 81. When the slider 6 locks the upper joint 1 and the lower joint 2, the first rotating shaft 8 just rotates to the position where the second key groove 82 is aligned with the stepped hole 15. The large shaft 521 of the stepped shaft 52 is re-embedded in the second key groove 82 under the action of the rebound force of the compression spring 53, and the stepped shaft 52 locks the first rotating shaft 8. At this time, the first rotating shaft 8 stops rotating, thereby locking the folder conveniently and quickly, and the locking device 5 can effectively prevent the accidental rotation of the foot pedal 7, which may cause the upper joint 1 and the lower joint 2 to be accidentally opened.

[0038] Please refer to Figure 2 and Figure 9 Due to the first key groove 81, when the upper joint 1 and the lower joint 2 are in the open state, the large shaft 521 of the stepped shaft 52 is embedded in the first key groove 81 under the rebound force of the compression spring 53, thereby effectively preventing the first rotating shaft 8 from automatically rotating and causing the rotating device 4 to automatically switch to the locked state.

[0039] In summary, the foot pedal 7 is connected to the rotating device 4 via the first rotating shaft 8. When the user steps on the opening end 72 of the foot pedal 7, the rotating device 4 drives the slider 6 to move away from the upper joint 1 and the lower joint 2. Without the slider 6 connected, the upper joint 1 and the lower joint 2 are in the open state. When the user steps on the locking end 71 of the foot pedal 7, the rotating device 4 drives the slider 6 to move toward the upper joint 1 and the lower joint 2. The slider 6 engages the first and second engaging grooves 12 and 22, respectively, via the first and second engaging grooves 61 and 62. The slider 6 connects the upper joint 1 and the lower joint 2 together, and the folder is locked. By rotatably connecting the pedal rod 51 to the upper joint 1, the stepped shaft 52 is hingedly connected to the pedal rod 51. When the user steps on the pedal rod 51, the pedal rod 51 drives the stepped shaft 52 to move in the stepped hole 15, and the large shaft 521 of the stepped shaft 52 compresses the compression spring 53. When the large shaft 521 of the stepped shaft 52 moves out of the second key groove 82, the stepped shaft 52 releases the lock on the first rotating shaft 8. At this time, the first rotating shaft 8 can be rotated by the foot pedal 7. When the stepped shaft 52 enters the second key groove 82 under the action of the rebound force of the compression spring 53, the automatic rotation of the first rotating shaft 8 can be prevented. Since the pedal rod 51 is arranged above the open end 72 of the foot pedal 7, the user only needs to step on it once to simultaneously release the lock of the stepped shaft 52 on the first rotating shaft 8 and the lock of the slider 6 on the upper joint 1 and the lower joint 2. By providing the compression spring 53, the user only needs to step on the locking end 71 of the foot pedal 7 once to simultaneously lock the slider 6 to the upper joint 1 and the lower joint 2, and the stepped shaft 52 to the first rotating shaft 8. Therefore, the operation is more convenient, and the user can easily and quickly lock and open the folder with his feet.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solutions of the present invention.
