Detailed Description

The present utility model will be described in further detail with reference to the accompanying drawings, for the purpose of making the objects, technical solutions and advantages of the present utility model more apparent.

As shown in fig. 1, a folding preservative film cutting slide comprises: a folder body 1 and a blade 2.

The folder body 2 includes: the upper combined piece 11 and the lower combined piece 12 are connected through a turnover connecting part 13, the turnover connecting part 13 comprises a concave position 131 arranged at the bottoms of the upper combined piece 11 and the lower combined piece 12 and a turnover hinge 132 connected with the upper combined piece and the lower combined piece, and a folding fixing structure 14 is arranged on a folding contact surface of the upper combined piece 11 and the lower combined piece 12.

It should be noted that, the concave portion 131 is used for compensating the convex portion generated by the folding page 132 due to folding, so that the folding page of the upper and lower combined parts 11 and 12 will not protrude from the lower surface of the cutting slide when the upper and lower combined parts are assembled in a folded manner.

The blade 2 has a through hole 21 which can be matched and clamped with the folding fixing structure 14, so that the blade 2 can be inserted between the upper and lower combined parts 11 and 12 to form a cutting slide knife.

As shown in fig. 2, the upper and lower combined parts 11 and 12 are both in an i shape, the upper parts of the upper and lower combined parts 11 and 12 are pressing parts, and the lower parts are sliding parts.

The buckling contact surface of the upper and lower combined parts 11 and 12 is provided with a folding fixing structure 14, the folding fixing structure 14 comprises a bolt 141 positioned on the upper combined part 11 and a plug hole 142 positioned on the lower combined part 12, and the upper and lower combined parts 11 and 12 are in folding buckling connection through the bolt 141 and the plug hole 142.

More preferably, the folding contact surfaces of the upper and lower combined parts 11 and 12 are provided with a blade accommodating concave position 16 matched with the shape of the blade, so that the blade 2 can be accommodated in the accommodating concave position 16 when clamped between the upper and lower combined parts 11 and 12.

As shown in fig. 3, the cutting slide device further comprises a slide groove 3, a first limiting point 31 is arranged at the bottom of the slide groove 3, a second limiting point 32 is arranged on the side wall of the tail end of the slide groove, and the cutting slide knife is slidably installed in the slide groove 3 and can be limited between the first limiting point 31 and the second limiting point 32.

It should be noted that, the two end surfaces of the sliding portion of the cutting slide have inclined wedge-shaped inclined planes 15, so when the sliding portion slides along the sliding groove 3, the wedge-shaped inclined planes 15 may cooperate with the first limiting point 31 and lift along the cambered surface of the first limiting point 31 until the cutting slide is excessively between the first limiting point 31 and the second limiting point 32, and in the process, the lifting of the first limiting point 31 may enable the top surface of the sliding portion to abut against the upper end surface of the sliding groove 3, so as to increase the sliding friction force of the cutting slide at the section, so that the cutting slide has a certain blocking feeling when being dragged to the tail end of the sliding groove 3.

As shown in fig. 4, the blade 2 has at least A, B, C, and may be divided into a single piece or multiple pieces and clamped in the middle of the cutting slide, the blade 2 has an inclined cutting inclined plane 22, and the angle of the cutting inclined plane 22 is 30 ° to 60 °, which can be specifically adapted and replaced according to actual use requirements, especially for film paper products with different toughness and thickness.

The above embodiments are merely for illustrating the technical concept and features of the present utility model, and are not intended to limit the scope of the present utility model to those skilled in the art to understand the present utility model and implement the same. All modifications made according to the spirit of the main technical proposal of the utility model should be covered in the protection scope of the utility model.
