[0002] Folding knives are commonly used tools in industrial manufacturing, but their blades are easily damaged or blunted during use, which shortens the service life of the tool. In order to solve this problem, a common practice is to provide a protective cover on the folding knife. For example, in the utility model patent with application number 202022957899.X, a new type of bending machine is disclosed, on which a protective cover is provided on the folding knife. The main purpose is to prevent the staff from getting injured by contact with the folding knife during use. However, the positioning ability of the folding knife of this structure is relatively weak, and a more stable positioning effect cannot be achieved, which may cause problems during bending.

[0003] In addition, in order to ensure that the bending knife can be firmly positioned at multiple positions, it is usually necessary to use multiple bolts for fixing. However, this method not only increases the complexity of installation, but also the installation effect of multiple bolts is not ideal.

[0004] Therefore, how to enhance the positioning function and facilitate installation while adopting a protective cover structure for the bending knife has become a key problem to be solved in current technology. Utility Model Content

[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 —6. In an embodiment of the utility model, a bending knife protection structure with excellent fitting effect includes a bending knife body 1, a bending knife protection cover 2 and a connecting mechanism 3.

[0033] The bending knife body 1 is a conventional industrial bending knife, mainly including a blade part 4. The bending knife protective cover 2 includes a blade fitting part 5 and a connecting plate part 6. The blade fitting part 5 is fitted on the blade part 4 of the bending knife body 1 in a clamping manner, protecting the blade part 4 from being damaged or blunted during use. The lower side of the connecting plate part 6 is fixedly connected to the blade fitting part 5, and more than 6 connecting mechanisms 3 are arranged on the front side thereof and close to the upper side of the connecting plate part 6.

[0034] The connecting mechanism 3 includes a mounting hole 7, a screw hole 8 and a bolt 9. The connecting plate portion 6 is provided with a mounting hole 7, the bending knife body 1 is provided with a screw hole 8 matching the mounting hole 7, and the bolt 9 passes through the mounting hole 7 and is fixedly connected with the screw hole 8, thereby realizing a fixed connection between the bending knife protective cover 2 and the bending knife body 1.

[0035] The number of connecting mechanisms 3 is specifically 21, and the mounting holes 7 of the 21 connecting mechanisms 3 are combined to form a connecting line, which is parallel to the blade line of the bending knife body 1, thereby ensuring the stability of the connection and the uniform distribution of the connection. The plastic film layer 10 surrounds the combination of the bending knife body 1 and the bending knife protective cover 2, and the topmost gap is blocked after the bending knife body 1 and the bending knife protective cover 2 are tightly matched, so as to better protect the bending knife body 1 and the bending knife protective cover 2, and the mounting hole 7 is blocked by the surrounding of the plastic film layer 10 to prevent the entry of dust or other debris, and when the bolt 9 penetrates the plastic film layer 10, the bolt 9 can be pre-positioned through the plastic film layer 10, so that the staff can use this The 21 bolts 9 penetrate the plastic film layer 10 in turn, and after being pre-positioned in the corresponding mounting holes, the user picks up a screwdriver in turn to tighten the 21 pre-positioned bolts 9 in turn, so as to achieve the effect of facilitating batch positioning and installation to improve efficiency. At the same time, the plastic film layer 10 can be, for example, a structure similar to plastic wrap. On the one hand, it has low cost of use. After it is wrapped around to form a layer, it can be positioned by utilizing the tightened property of its main body. Moreover, when the bolt 9 passes through, this film structure that is easily tightened is relatively easy to be pierced by the action of the screw penetrating into the mounting hole and the screw hole 8, so as to achieve the pre-positioning effect of being tightly wrapped by the film after piercing. The bolt 9 can be a pointed bolt to facilitate piercing, which are all extended implementation methods known to ordinary technicians in this field.

[0036] Embodiment 1:

[0037] The folding knife protective cover 2 is attached to the blade part 4 of the folding knife body 1 by a clamping manner through the blade attachment part 5, so as to protect the blade and prevent it from being damaged or blunted during use, thereby effectively extending the service life of the folding knife.

[0038] At the same time, in order to achieve a stable fixed connection between the bending knife protective cover 2 and the bending knife body 1, the structure adopts an improved connecting mechanism 3. The connecting mechanism 3 includes a mounting hole 7, a screw hole 8 and a bolt 9. The connecting plate part 6 is provided with a mounting hole 7, and the bending knife body 1 is provided with a screw hole 8 that matches the screw hole 8. The bolt 9 passes through the mounting hole 7 and is fixedly connected with the screw hole 8, thereby achieving a fixed connection between the bending knife protective cover 2 and the bending knife body 1. This connection method not only ensures the stability of the connection, but also improves the uniformity and effect of the connection by optimizing the number and distribution of the connecting mechanisms 3.

[0039] In addition, in order to prevent dust or other debris from entering and affecting the connection effect, and to facilitate the pre-positioning of the bolts 9 to improve the sequential tightening of the bolts 9, a plastic film layer 10 is used to seal the top gap and the mounting hole 7. On the one hand, it prevents dust or other debris from entering and plays a role in the use of matching gap inclusion. On the other hand, when the bolts 9 penetrate the plastic film layer 10, it is convenient to pre-position the bolts 9 through the plastic film layer 10. For example, the staff can use this to penetrate 21 bolts 9 in turn through the plastic film layer 10. After pre-positioning in the corresponding mounting holes, the user picks up a screwdriver in turn to tighten the 21 pre-positioned bolts 9 in turn, thereby achieving the effect of facilitating batch positioning installation to improve efficiency, and avoiding the need to pick up a bolt 9 and tighten it with a screwdriver in the prior art, and then pick up another bolt 9 and tighten it with a screwdriver, which requires multiple intermittent cycles of the same step.

[0040] Furthermore, the utility model achieves a more stable installation by using a plurality of bolts 9, and adopts the plastic film layer 10, which not only effectively blocks and seals the top position of the bending knife body 1 and the bending knife protective cover 2, but also improves the pre-positioning efficiency of the bolts 9 through the plastic film layer 10, making batch positioning installation more convenient, thereby enhancing the positioning function of the bending knife body 1, facilitating installation and increasing service life.
