When the single board clamp of the embodiment is used, the single board clamp can conveniently switch the direction of clamping paper. When the veneer is clamped on top of the carrier plate 1, the clamp 5 can clamp the paper transversely, the connecting shaft 4 is positioned at the left end of the limiting chute 2-5, if the veneer clamp is to be converted into clamping the paper longitudinally at the left side of the carrier plate 1, the right end of the clamp 2 can be pulled upwards, the clamp 2 rotates anticlockwise around the connecting shaft 4 until the right part of the clamp 2 is separated from the carrier plate, as shown in fig. 2, then the clamp slides leftwards and downwards relative to the connecting shaft until the connecting shaft 4 is limited by the right end of the limiting chute, as shown in fig. 3, at the moment, the clamping groove is opposite to the left side of the carrier plate 1, the clamp 2 can rotate anticlockwise around the connecting shaft 4 until the left side of the carrier plate 1 is inserted into the clamping groove and clamped by the clamp 2, as shown in fig. 4, at the moment, the veneer clamp can clamp the paper longitudinally at the left side of the carrier plate, and at the same time, the connecting shaft 4 is positioned at the upper end of the limiting chute.

Example 2:

As shown in fig. 6 to 10, the single board clip of the present embodiment is different from embodiment 1 in that the structure of the clip member 2 is different, and the manner of connection of the clip member 2 and the carrier board 1 is also different. In this embodiment, the clamping member 2 also includes a front clamping plate 2-1, a rear clamping plate 2-2, and a clamping groove between the front clamping plate 2-1 and the rear clamping plate 2-2, the front clamping plate 2-1 is also provided with a clamp 5 for clamping paper, and a protruding structure is provided on the inner side of the rear clamping plate 2-2, in this embodiment, the protruding structure is a protruding strip 2-7; when the clamping piece 2 is clamped on the carrier plate 1, the carrier plate 1 is inserted into the clamping groove, the front clamping plate 2-1 and the rear clamping plate 2-2 are respectively arranged on the upper side and the lower side of the carrier plate 1, and the convex strips 2-7 are abutted against the lower bottom surface of the carrier plate 1, so that the carrier plate 1 is clamped by the clamping piece 2; but unlike embodiment 1, a connecting rod 3 is provided between the holder 2 and the carrier plate 1, one end of the connecting rod 3 is hinged with the rear clamping plate 2-2 at the holder hinge hole 2-8, and the other end is hinged with the upper left part of the carrier plate 1 at the carrier plate hinge hole 1-2.

When the veneer clamp of the embodiment is used, the direction of clamping paper can be conveniently switched by the veneer clamp. When the single board clamps the paper transversely at the top of the carrier plate 1, the clamping piece 2 can be pulled upwards to enable the clamping piece 2 to be completely separated from the carrier plate 1 when the paper is to be longitudinally clamped at the left side of the carrier plate 1, in the process, the clamping piece 2 and the connecting rod 3 and the carrier plate 1 are rotated relatively, then the clamping piece 2 rotates anticlockwise relative to the connecting rod 3 and the connecting rod 3 rotates anticlockwise relative to the carrier plate 1 until the clamping groove is opposite to the left side of the carrier plate 1, the clamping piece 2 can be pushed to the left side of the carrier plate 1 until the left side of the carrier plate 1 is inserted into the clamping groove and clamped by the front clamping plate 2-1 and the rear clamping plate 2-2, and at the moment, the single board clamp is converted into the paper longitudinally clamped at the left side of the carrier plate, as shown in fig. 8 and 9.

The above steps can be reversed to pull the clamping member 2 leftwards to separate the clamping member 2 from the carrier plate 1 completely, and in this process, the clamping member 2 and the connecting rod 3 and the carrier plate 1 are rotated relatively, and then the clamping member 2 rotates clockwise relative to the connecting rod 3 and the connecting rod 3 rotates clockwise relative to the carrier plate 1 until the clamping groove is opposite to the top of the carrier plate 1, and the clamping member 2 can be pushed to the top of the carrier plate until the top of the carrier plate 1 is inserted into the clamping groove and clamped by the front clamping plate 2-1 and the rear clamping plate 2-2, at this time, the single plate clamp is converted to clamp the paper at the top of the carrier plate transversely, as shown in fig. 6 and 7.

In this embodiment, when the single plate clamp is switched to the clamping position, the clamping member 2 rotates along with the connecting rod 3 with the carrier plate hinge hole 1-2 as the center of a circle, and the length of the connecting rod 3 between the carrier plate hinge hole 1-2 and the clamping member hinge hole 2-8 is the radius. It may be arranged that the clamping member 2 is located at the center of the top of the carrier plate 1 when the top of the carrier plate 1 is inserted into the opposite clamping groove; when the side of the carrier plate 1 is inserted into the opposite clamping groove, the clamping piece 2 is positioned at the middle position of the side of the carrier plate 1.

For example, the front clamping plate 2-1 and the rear clamping plate 2-2 are symmetrical in front-back, and the clamping piece hinge hole 2-8 is positioned at the center of the rear clamping plate 2-2; when the top of the carrier plate 1 is inserted into the clamping groove, the clamping piece hinge holes 2-8 are positioned at the center of the top of the carrier plate 1; when the left side part of the carrier plate 1 is inserted into the clamping groove, the clamping piece hinge holes 2-8 are positioned at the middle position of the left side part of the carrier plate 1; an auxiliary design line segment is drawn between the middle position of the top of the carrier plate 1 and the middle position of the left side part of the carrier plate 1, the carrier plate hinge hole 1-2 is arranged on the middle vertical line of the auxiliary design line segment, and the position of the carrier plate hinge hole 1-2 on the middle vertical line is adjusted, so that the distance between the carrier plate hinge hole 1-2 and the middle position of the top of the carrier plate 1 or the middle position of the left side part of the carrier plate 1 is equal to the length of the connecting rod 3 between the carrier plate hinge hole 1-2 and the clamping piece hinge hole 2-8. Therefore, whether the clamping piece 2 transversely clamps the paper at the top of the carrier plate 1 or longitudinally clamps the paper at the side part of the carrier plate 1, the clamping piece 2 can be positioned at the middle position of the corresponding side of the carrier plate 1, and the clamp 5 can also clamp the middle position of the corresponding side of the paper.

For another example, the clamp hinge hole 2-8 is not provided at the center of the rear clamping plate 2-2, and the distances between the clamp hinge hole 2-8 and the left and right ends of the rear clamping plate 2-2 are a and b, respectively, and b > a; the lengths of the longitudinal long side and the transverse wide side of the carrier plate 1 are H and L respectively, and H is more than L; the distance between the carrier plate hinge hole 1-2 and the top of the carrier plate 1 and the distance between the carrier plate hinge hole 1-2 and the left side of the carrier plate 1 are equal and are c; the length of the connecting rod 3 between the carrier plate hinge holes 1-2 and the clamping piece hinge holes 2-8 is d; when the top of the carrier plate 1 is inserted into the clamping groove, the connecting rod 3 is arranged to be parallel to the transverse broadside of the carrier plate 1; when the left side part of the carrier plate 1 is inserted into the clamping groove, the connecting rod 3 is parallel to the longitudinal long side of the carrier plate 1; the above length relationships are set to H-l=2 x (b-a), and h+l=4 x (d+c), which also ensures that the clamping member 2 can be located at the middle position of the corresponding side of the carrier plate 1, and the clamping member 5 can be located at the middle position of the corresponding side of the paper, regardless of whether the clamping member 2 clamps the paper laterally on the top of the carrier plate 1 or clamps the paper longitudinally on the side of the carrier plate 1.

This is because, when the top of the carrier plate 1 is inserted into the clip groove, the clip hinge holes 2-8 are spaced from the left side of the carrier plate 1 by a distance (c+d); the distance between the hinge holes 2-8 of the clamping piece and the center position of the top of the carrier plate 1 is (c+d) -L/2, and the lengths are brought into the above-mentioned length relations, namely, the distance between the hinge holes 2-8 of the clamping piece and the center position of the top of the carrier plate 1 is (H-L)/4; the distance between the hinge hole 2-8 of the clamping member and the center position of the rear clamping plate 2-2 is b- (b+a)/2, and the length relationships are brought into the above-mentioned respective length relationships, namely, the distance between the hinge hole 2-8 of the clamping member and the center position of the rear clamping plate 2-2 is (H-L)/4. The distance between the hinge holes 2-8 of the clamping piece and the center position of the top of the carrier plate 1 is equal to the distance between the hinge holes 2-8 of the clamping piece and the center position of the rear clamping plate 2-2, and the clamping piece 2 is positioned at the center position of the top of the carrier plate 1.

When the left side part of the carrier plate 1 is inserted into the clamping groove, the distance between the clamping piece hinge holes 2-8 and the top of the carrier plate 1 is (c+d); the distance between the clamping piece hinge holes 2-8 and the center position of the left side part of the carrier plate 1 is H/2- (c+d), and the lengths are brought into the above-mentioned length relations, namely, the distance between the clamping piece hinge holes 2-8 and the center position of the left side part of the carrier plate 1 is (H-L)/4; while the distance between the hinge hole 2-8 of the clamping member and the center position of the rear clamping plate 2-2 is still (H-L)/4.

Example 3:

The single board clip of this embodiment is different from embodiment 2 in the manner of connecting the clip 2 and the carrier 1. In this embodiment, when the clamping member 2 is flexibly connected with the carrier plate 1 through the long spring and the clamping member 2 switches the direction of clamping paper, the clamping member 2 is pulled out of the carrier plate 1, then the clamping groove is opposite to the top or the side of the carrier plate 1, and then the clamping member 2 is pushed to the top or the side of the carrier plate until the top or the side of the carrier plate is inserted into the clamping groove, so that the paper can be clamped by the single plate at the top or the side of the carrier plate, and the operation is convenient. In this embodiment, the clamping member 2 may be flexibly connected to the carrier plate 1 by a string.

The foregoing is merely exemplary of the present invention and is not intended to limit the scope of the present invention; modifications and equivalent substitutions are intended to be included in the scope of the claims without departing from the spirit and scope of the present invention.
