AI Technical Summary
The length of the existing blade is fixed, which leads to insufficient length when cutting materials. It needs to be cut in two times, which can easily lead to dimensional errors.
A combined blade is designed to bolt the movable blade to the first blade, which can be spliced to extend the cutting length and to achieve a removable connection through the fitting of the fixing frame and the hole.
It realizes flexible extension of cutting length, avoids dimensional errors caused by secondary cutting, and improves cutting precision and efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of blades, in particular to a combined blade. Background Art
[0002] A blade is the part of a knife, weapon, or machine whose edge is designed to pierce, cut, or scrape a surface. Blades can be made of materials such as flint, metal (usually steel), ceramic, or other materials.
[0003] According to the investigation, the blades in the prior art are all provided with a cutting edge for cutting a certain material;
[0004] Reference URL (blade in prior art):
[0005] https: / / 14751634.s21i.faiusr.com / 2 / 1 / ABUIABACGAAgouir8AUowuDlJDCgBjigBg%21400x400.jpg
[0006] This will have the following disadvantages:
[0007] The length of the blade is fixed. If the cutting material is too long during cutting, the length of the blade is not enough for the length of the material, which is inconvenient for cutting. If it is cut in two times, the size will not be as precise as that of one cut, and cutting in two times may result in different sizes of the two cuts, which is easy to cause errors.
[0008] In summary, the present application now proposes a combined blade to solve the above-mentioned problems. Utility Model Content
[0009] The purpose of the utility model is to provide a combined blade to solve the problems raised in the above background technology.
[0010] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a combined blade includes a handle; a knife sleeve is detachably mounted on the handle; a bolt is threadedly connected to the knife sleeve, and the bolt passes through the knife sleeve and a first blade is detachably mounted thereon, and a movable blade is detachably mounted on the outside of the first blade; the movable blades are provided in multiple groups and can be spliced and mounted with each other.
[0011] Preferably, a movable blade is further included; fixing frames are fixedly welded on both sides above the movable blade, and one end of the fixing frame exceeds the length of the movable blade body.
[0012] Preferably, one end of the first blade is provided with a hole; and both ends of the fixing frame are provided with a hole.
[0013] Preferably, the hole on the fixing frame and the hole on the first blade are detachably connected by bolts passing through them.
[0014] Preferably, a storage box is fixedly connected to one side of the handle; and a lid is rotatably connected to the bottom of the storage box.
[0015] Preferably, an anti-slip sleeve is installed on the outer side of the handle.
[0016] Preferably, the anti-slip cover is made of silicone.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention uses bolts to detachably mount the movable blade on the first blade, thereby extending the cutting length; holes are provided on both sides of the fixed frame, through which the movable blade can be reconnected to continuously increase the cutting length, thereby avoiding the possibility of errors in the two cutting sizes caused by the fixed blade during secondary cutting; and the bolt fixing / disassembly can facilitate disassembly, replacement or maintenance by the staff.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, it should be noted that the embodiments in this application and the features in the embodiments can be combined with each other unless there is a conflict.
[0026] See also Figure 1-6The utility model provides a technical solution: a combined blade includes a handle 1, the handle 1 has a cylindrical structure, and the handle 1 is held by hand to facilitate the movement of the blade. A knife sleeve 5 is detachably installed on the handle 1 for fixing the position of the blade, and the knife sleeve 5 has a U-shaped structure. An array of bolts 6 is threadedly connected to the knife sleeve 5, and a first blade 8 (a hole is provided at one end of the first blade 8) is detachably installed through the bolts 6 passing through the knife sleeve 5. The first blade 8 is fixed by the bolts 6, and a movable blade 7 is detachably installed on the outside of the first blade 8. The movable blades 7 are provided in multiple groups and can be spliced and installed with each other.
[0027] Specifically, the length of the movable blade 7 can be set according to the specific actual required length (the length of the movable blade 7 of the utility model is smaller than the length of the first blade 8), and a fixing frame 9 is fixedly welded on both sides above the movable blade 7. The fixing frame 9 is a rectangular parallelepiped, and the fixing frame 9 is in a horizontally parallel state. A hole is provided at both ends of the fixing frame 9, and one end of the fixing frame 9 exceeds the length of the movable blade 7 body. From a top view, the structure of the movable blade 7 and the fixing frame 9 is a concave shape.
[0028] Furthermore, the hole on the fixing frame 9 and the hole on the first blade 8 are detachably connected through a bolt 6, which is used to extend the cutting length of the first blade 8. The detachable connection of the bolt 6 facilitates the replacement and maintenance of the blade. If the length is not enough, the connection can be continuously increased through the movable blade 7. After the cutting is completed, it can also be disassembled through the bolt 6.
[0029] It also includes a storage box 3 fixedly connected to one side of the handle 1. The storage box 3 is a rectangular cavity structure. A lid 4 is rotatably connected to the bottom of the storage box 3 for opening / closing the storage box 3. The function of the storage box 3 is to store the movable blade 7.
[0030] An anti-slip cover 2 is also installed on the outside of the handle 1. The material of the anti-slip cover 2 is silicone. When holding the handle 1, it can increase friction and prevent the palms from sweating due to holding the handle 1 for too long, thereby achieving an anti-slip effect.
[0031] The utility model uses a bolt 6 to detachably mount the movable blade 7 on the first blade 8, which has the effect of extending the cutting length. Holes are provided on both sides of the fixing frame 9, and the movable blade 7 can be connected again through the holes to continuously increase the cutting length, thereby increasing the flexibility of the cutting length.
[0032] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
[0033] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "provided with," "connected," etc. should be understood in a broad sense. For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on the specific circumstances.
