[0022] This application provides a double-sided writing folding clip, which solves the problem that folding clips cannot facilitate writing on both sides of the paper.
[0023] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.
[0024] Example:
[0025] like Figure 1 , Figure 2 As shown, this utility model provides a double-sided writing folding clip, which includes: a bushing 1, a folding plate 2, a first clamping piece 3, and a second clamping piece 4;
[0026] The bushing 1 is provided with a clamping shaft and two sets of folding shafts. The two folding shafts 2 are respectively hinged to the bushing 1 through the corresponding folding shafts. The first clamping piece 3 and the second clamping piece 4 are both hinged to the bushing 1 through the clamping shaft.
[0027] A torsion spring is provided on the clamping shaft. One end of the torsion spring is connected to the first clamping plate 3, and the other end is connected to the second clamping plate 4. The first clamping plate 3 and the second clamping plate 4 are clamped together by the torsion spring.
[0028] like Figure 1 , Figure 2 As shown, the clamping shaft and the two sets of folding shafts are parallel to each other, and the axes of the three shafts are arranged in a triangular pattern.
[0029] like Figure 1 , Figure 2 As shown, the first clamping piece 3 and the second clamping piece 4 are arranged in an alternating manner, so that each of the first clamping piece 3 and the second clamping piece 4 has a section that does not participate in clamping, which serves as the force point for opening the clamping piece.
[0030] like Figure 1 , Figure 2 As shown, the outer wall of the first clamping plate 3 is provided with a first pusher 5, and the outer wall of the second clamping plate 4 is provided with a second pusher 6. The first pusher 5 and the second pusher 6 also serve as the force points for opening the clamping plates, and are used when it is inconvenient to apply force to the non-clamping sections of the first clamping plate 3 and the second clamping plate 4.
[0031] like Figure 1 As shown, the hinge 2 has an avoidance opening 7, which provides avoidance space for the first pusher 5 and the second pusher 6, preventing the hinge 2 from interfering with the first pusher 5 or the second pusher 6.
[0032] like Figure 1 , Figure 2As shown, the outer end of the bushing 1 has two outer shaft holes for installing two folding shafts; the inner end of the bushing 1 has an inner shaft hole for installing a clamping shaft; the two bushings 1 are respectively installed at both ends of the clearance opening 7.
[0033] like Figure 1 , Figure 2 As shown, the first clamping piece 3 and the second clamping piece 4 are both eccentrically arranged relative to the clamping shaft, so that the axis of the clamping shaft is located between the first clamping piece 3 and the second clamping piece 4, ensuring the clamping contact area of the first clamping piece 3 and the second clamping piece 4 and improving the paper clamping effect.
[0034] like Figure 1 As shown, when the two folds 2 are parallel, the distance between them is greater than the thickness of the first clamping piece 3 plus the thickness of the second clamping piece 4, so that when the paper clamped by the folding clamp does not exceed the rated thickness, the fold 2 closes flat and will not open.
[0035] In summary, compared with the prior art, the present invention has the following beneficial effects:
[0036] In this embodiment of the utility model, the folding clamp is provided with two sets of folding shafts and one clamping shaft. The two folds 2 are respectively hinged to the corresponding folding shafts. The first clamping piece 3 and the second clamping piece 4 are both hinged to the clamping shaft. The clamping shaft is provided with a torsion spring that drives the first clamping piece 3 and the second clamping piece 4 to clamp each other, which ensures that the paper can be clamped and fixed. As the first clamping piece 3 and the second clamping piece 4 rotate around the clamping shaft, the clamped paper can be flatly placed on any fold at any angle, which is convenient for writing on both sides of the paper.
