AI Technical Summary
Existing accounting voucher holders have a reduced service life because the torsion springs need to withstand a large torsional angle, which can lead to metal fatigue or breakage.
The design incorporates a rotating first clamp and a second clamp, along with a rotating plate, a torsion spring, and a second spring. By separating the rotating plate from the first clamp, the torsion spring stops rotating, and the second spring provides clamping force, thus increasing clamping stability.
When holding thicker documents, the torsion spring no longer twists, reducing the risk of metal fatigue damage, increasing the durability of the document holder, and ensuring continuous clamping effect.

[0034] Example
[0035] like Figures 1-6 As shown, the accounting voucher holder includes a first clamping rod 11 and a second clamping rod 12 that are rotatably connected. The two are rotatably connected by a rotating shaft 13. A first clamping plate is rotatably connected to one end of the first clamping rod 11, and a second clamping plate is fixed to one end of the second clamping rod 12. The accounting vouchers are held by the first clamping plate and the second clamping plate.
[0036] In one embodiment, such as Figures 2-4 As shown, a rotating plate 21 is provided between the first clamping rod 11 and the second clamping rod 12. A rectangular slit 111 is provided on the first clamping rod 11. Initially, the rotating plate 21 is locked in the rectangular slit 111. The rotating plate 21 is rotatably connected to a rotating shaft 13. A torsion spring is sleeved on the rotating shaft 13. The torsion spring is located between the rotating plate 21 and the second clamping rod 12. The torsion spring is used to provide force to the second clamping rod 12 and the rotating plate 21. Initially, the rotating plate 21 and the first clamping rod 11 are locked together as one unit, that is, the torsion spring is used to provide force to the second clamping rod 12 and the first clamping rod 11 for clamping accounting documents.
[0037] In one embodiment, such as Figures 2-5As shown, the bottom of the rotating plate 21 is connected with the clamping block 22 through the slide rail, and the clamping block 22 is initially clamped on the first clamping rod 11. In the initial state, the rotating plate 21 is clamped on the first clamping rod 11, and the rotating plate 21 rotates together with the first clamping rod 11. At this time, the first clamping rod 11 acts on the torsion spring through the rotating plate 21, and the torsion spring applies force to the first clamping rod 11, so that the first clamping plate of the first clamping rod 11 and the second clamping plate of the second clamping rod 12 clamp the accounting voucher.
[0038] In one embodiment, as shown in Figures 2-5 As shown, the top of the second clamping rod 12 is provided with a top block 121, and the top block 121 is matched with the clamping block 22 through the clamping groove 122, so that the clamping block 22 is separated from the first clamping rod 11. When the first clamping rod 11 is parallel to the second clamping rod 12, the top block 121 extrudes the clamping block 22, so that the clamping block 22 is separated from the first clamping rod 11. When the first clamping rod 11 and the second clamping rod 12 are gradually rotated to the parallel state, the top block 121 acts on the clamping block 22. With the top block 121 continuing to approach the clamping block 22, the clamping groove 122 extrudes the two ends of the clamping block 22 to separate from the limiting block 113, and the two clamping blocks 22 are located below the rotating plate 21, so that the rotating plate 21 and the first clamping rod 11 are separated. Because the elastic coefficient of the second spring 24 is greater than that of the torsion spring, the first clamping rod 11, the second clamping rod 12 and the rotating plate 21 remain in a relatively stable state.
[0039] In one embodiment, as shown in Figures 2-5 As shown, the bottom of the rotating plate 21 is connected with the clamping block 22 through the slide rail, and the clamping block 22 is initially clamped on the first clamping rod 11. In the initial state, the rotating plate 21 is clamped on the first clamping rod 11, and the rotating plate 21 rotates together with the first clamping rod 11. At this time, the first clamping rod 11 acts on the torsion spring through the rotating plate 21, and the torsion spring applies force to the first clamping rod 11, so that the first clamping plate of the first clamping rod 11 and the second clamping plate of the second clamping rod 12 clamp the accounting voucher.
[0040] In one embodiment, as shown in Figure 6As shown, the first clamping rod 11 is provided with a limiting block 113 on the inner side, the limiting block 113 is used for limiting the sliding position of the clamping block 22, and the rotating plate 21 is synchronously rotated with the first clamping rod 11, the rotating plate 21 is constrained to rotate with the first clamping rod 11 through the limiting block 113, and the second spring 24 is in a stretched state in the initial state, the purpose of the limiting block 113 is to prevent the rotating plate 21 from rotating towards the direction close to the second clamping rod 12 under the pulling force of the second spring 24, so as to cause the rotating plate 21 to separate from the first clamping rod 11, and ensure that the first clamping plate of the first clamping rod 11 can exert force on the accounting voucher.
[0041] In one embodiment, as shown in Figures 2-6 The clamping block 22 is provided with two clamping blocks 22, and the two clamping blocks 22 are located on both sides of the rotating plate 21 and are slidably connected with the rotating plate 21 through a sliding rail, and the first spring 23 is arranged between the two clamping blocks 22, the first spring 23 is configured to reset the two clamping blocks 22 to the initial position after the clamping block 22 is released by the top block 121, and when the first clamping rod 11 and the second clamping rod 12 are not in the parallel state and are in the open state, the first spring 23 resets the two clamping blocks 22, so that the clamping block 22 is clamped in the limiting block 113 of the first clamping rod 11, and the rotating plate 21 can rotate with the first clamping rod 11.
[0042] In one embodiment, as shown in Figures 2-6 The angle between the inclined edge of the clamping block 22 and the vertical surface is 60 degrees, so that the clamping block 22 is driven to slide through the clamping groove 122 of the top block 121, and the component force in the moving direction of the clamping block 22 is increased.
[0043] The technical scope of the utility model is not limited to the content in the above description, and those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical thought of the utility model, and these deformations and modifications should all belong to the protection scope of the utility model.
