[0027] The driving mechanism comprises a pushing mechanism and a reset mechanism, wherein the pushing mechanism is connected to the first fastening member (6), and the reset mechanism is connected between the first fastening member (6) and the operating rod (2). The pushing mechanism comprises a push button (63), and the reset mechanism comprises an elastic reset member (8). The elastic reset member 8 in this example is a spring, but may also be an elastic member such as a shrapnel or a torsion spring. The reset mechanism is used to keep the first fastening member in a position where it can be connected to the second fastening member, and the pushing mechanism is used to push the first fastening member away from the connection with the second fastening member.

[0028] The operating rod (2) is provided with a slide groove (21), the slide groove (21) extends along the length direction of the operating rod 2, the first buckle member (6) comprises a slider (61), the slider (61) is slidably connected in the slide groove (21), the slider (61) is provided with a buckle portion (62), the buckle portion (62) is a first barb (621), and the first barb (621) is connected to the lower end surface of the slider (61). The push button (63) is connected to the upper end surface of the slider (61) and is located above the operating rod 2.

[0029] The elastic reset member (8) is sleeved on the torsion arm at one end of the torsion spring (5). A first protrusion (22) is provided on the lower end surface of the operating rod (2) near the main shaft (4), and a guide groove (221) is provided on the first protrusion (22) for the torsion arm at one end of the torsion spring (5) to pass through. A through hole (611) is provided on the slider (61). The torsion arm at one end of the torsion spring (5) passes through the guide groove (221), the elastic reset member (8) and the through hole (611) in sequence, and is slidably connected with the slider (61). One end of the elastic reset member (8) abuts against the first protrusion (22) and is connected thereto, and the other end abuts against the slider (61) and is connected thereto. The elastic reset member (8) keeps the first buckle member 6 at the end of the slide groove 21 away from the main shaft 4. The torsion arm at one end of the torsion spring 5 can serve as a guide rod for the slider and the elastic reset member.

[0030] The second fastening member (7) is a second barb (71), and the first barb (621) can be connected to the second barb (71) by being fastened to each other. The upper surface of the second barb (71) is an inclined surface 710, and the inclined surface 710 faces the first fastening member 6, that is, the main shaft 4. The end of the first barb (621) is provided with a straight wall (6211), and the end of the second barb (71) is provided with a straight wall (711).

[0031] The working principle and action process of the folder clamp in this example:

[0032] Locking process: Press the operating rod 2 with your finger, the operating rod 2 rotates downward around the main shaft 4, the first hook (621) at the lower end of the first fastener 6 contacts the inclined surface of the second hook (71), as the operating rod 2 continues to rotate downward, the first fastener 6 is subjected to the component force of the inclined surface of the second hook (71) reacting to the first hook (621) in the direction of the main shaft 4, so the first fastener 6 will slide along the torsion arm of the torsion spring 5 in the direction of the main shaft 4. When the first hook (621) moves to the end of the inclined surface of the second hook (71), the first fastener 6 will slide along the torsion arm of the torsion spring 5 away from the main shaft due to the spring restoring force, and then the first hook (621) hooks the second hook (71), and the locking is completed at this time.

[0033] Unlocking process: The finger is pressed on the push button 63 of the first fastener 6. Due to the anti-accidental touch design, the second hook (71) and the first hook (621) are both provided with a straight wall at the end. Therefore, it is impossible to unlock by directly pushing the push button 63 in the direction of the main shaft 4. The finger must first press the push button 63 downward for a certain distance, and then push the push button 63 in the direction of the main shaft 4 to make the first hook (621) disengage from the second hook (71). Then, due to the restoring force of the torsion spring 5, the operating rod 2 rotates upward to complete the unlocking.

One end of the elastic reset member (8) abuts against the second protrusion (23), and the other end abuts against the slider (61), and the elastic reset member (8) keeps the first buckle member 6 located at the end of the slide groove 21 close to the main shaft 4.

[0036] The upper surface of the second barb (71) is an inclined surface 710, which faces the first fastener 6 and faces away from the main shaft 4. The end of the first barb (621) is provided with a straight wall (6211), and the end of the second barb (71) is also provided with a straight wall (711).

[0037] The working principle and action process of the folder clamp in this example:

[0038] Locking process: Press the operating rod 2 with your finger, the operating rod 2 rotates downward around the main shaft 4, the first hook (621) at the lower end of the first fastener 6 contacts the inclined surface of the second hook (71), as the operating rod 2 continues to rotate downward, the first fastener 6 is subjected to the component force of the inclined surface of the second hook (71) reacting to the first hook (621) away from the main shaft 4, so the first fastener 6 will slide along the torsion arm of the torsion spring 5 away from the main shaft 4. When the first hook (621) moves to the end of the inclined surface of the second hook (71), the first fastener 6 will slide along the torsion arm of the torsion spring 5 toward the main shaft due to the spring restoring force, and then the first hook (621) hooks the second hook (71), and the locking is completed at this time.

[0039] Unlocking process: the finger presses the push button 63 downward for a certain distance, and then pushes the push button 63 away from the main shaft 4 to make the first barb (621) disengage from the second barb (71). Then, due to the restoring force of the torsion spring 5, the operating rod 2 rotates upward to complete the unlocking.

As the operating rod 2 continues to rotate downward, the third hook 622 enters the buckle hole 72 through the opening 721. At this time, release the push button 63, and the first buckle 6 slides away from the main shaft 4 under the action of the elastic reset member (8). The third hook 622 reaches the end of the buckle hole 72 away from the opening 721, and the locking is completed.
