[0026] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0027] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0028] In the present invention, unless otherwise expressly specified or limited, when a first feature is "above" or "below" a second feature, it may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediary.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only implementation methods.

[0030] Physical quantities in formulas, unless otherwise specified, should be understood as basic quantities of the International System of Units (SI) basic units, or derived quantities derived from basic quantities through mathematical operations such as multiplication, division, differentiation or integration.

[0031] Example:

[0032] refer to Figure 1-Figure 3The cam 2 is provided with a plurality of locking means, and the locking means 21 is provided with a plurality of locking means, and the locking means 22 is provided with a plurality of locking means, and the plurality of locking means 23 are provided with a plurality of locking means, and the plurality of locking means 24 are provided with a plurality of locking means. A blade 4 is installed on the clamping seat 3, and a handle 11 is slidably fitted on the knife handle 1. The handle 11 is connected to a threaded rod 12, and a connecting hole 22 is provided on the mounting frame 2. The connecting hole 22 can be a threaded hole, and the other end of the threaded rod 12 is connected to the connecting hole 22. A limiting through hole 111 is provided on the handle 11, and the rod body of the threaded rod 12 passes through the limiting through hole 111 and is threadedly fitted with the connecting hole 22, so that the mounting frame 2 is fixed to the knife handle 1 through the locking bolt 34, and the head of the threaded rod 12 is engaged with the limiting through hole 111. Because the head of the threaded rod 12 is stuck on the handle 11, the threaded rod 12 can be rotated by rotating the handle 11, and then the mounting frame 2 can be detachably fixed to one end of the knife handle 1 by tightening the threaded rod 12, which facilitates the replacement of the tool clamping seat 3, thereby reducing the impact of replacing the blade 4 or the knife seat on production efficiency.

[0033] refer to Figure 1 and Figure 2 The angle positioning pins include a first angle positioning pin 31 and a second angle positioning pin 32 which are respectively fixed at the two ends of the bottom of the tool holder 3 by interference fit or fixation. The diameters of the first angle positioning pin 31 and the second angle positioning pin 32 are different. Thus, the first angle positioning pin 31 and the second angle positioning pin 32 of different diameters can prevent the tool holder 3 from being installed upside down, thereby preventing mistakes. The angle adjustment hole includes an arc-shaped first angle adjustment hole 23 and a second angle adjustment hole 24. The first angle positioning pin 31 slides with the first angle adjustment hole 23, and the second angle positioning pin 32 slides with the second angle adjustment hole 24. The arc-shaped design of the first angle adjustment hole 23 and the second angle adjustment hole 24 enables more angle adjustments to be made to the blade 4. At this time, the second locking hole 21 is opened as an arc-shaped long waist hole, and the locking bolt 34 slides with the second locking hole 21. One end of the locking bolt 34 passes through the first locking hole and the second locking hole 21 and locks the tool holder 3 on the mounting frame 2 through a nut. Thus, the blade 4 can be adjusted to more angular positions through the first angle adjustment hole 23 , the second angle adjustment hole 24 and the second locking hole 21 .

[0034] refer to Figure 2 and Figure 3 As another embodiment, the angle adjustment hole can also be a pin hole opened according to the set angle, and the second locking hole 21 is a threaded hole that matches the angle adjustment hole. However, in this way, the adjustable angle of the blade 4 can only be adjusted to a fixed angle according to the angle of the pin hole and the threaded hole opened at the set angle. One end of the locking bolt 34 can be directly threadedly connected to the second locking hole 21, so that the locking bolt 34 is rotated to lock the mounting frame 2 on the knife handle 1.

[0035] refer to Figure 1 and Figure 2 The bottom of the shank 1 is interference-fitted or fixedly connected with a first mounting positioning bolt 13 and a second mounting positioning bolt 14 of different diameters. The mounting frame 2 is provided with a first mounting positioning hole 25 respectively cooperating with the first mounting positioning bolt 13 and a second mounting positioning hole 26 cooperating with the second mounting positioning bolt 14. The first mounting positioning hole 25 or the second mounting positioning hole 26 is a long waist hole. The design of the long waist hole can reduce the processing and installation accuracy requirements. The first mounting positioning bolts 13 and the second mounting positioning bolts 14 of different diameters also play a role in preventing the mounting frame 2 from being installed upside down, thereby preventing mistakes.

[0036] refer to Figure 2 and Figure 3 The tool holder 3 is provided with a large blade groove 35, into which the blade 4 is mounted. To accommodate the mounting of the small blade 4, a small blade groove 36 is provided in the blade groove, so that both large and small blades 4 can be mounted in one tool holder 3, saving costs. A pressure cap 37 for clamping the blade 4 is screwed to the tool holder 3, thereby clamping the blade 4 in the blade groove.

[0037] refer to Figure 1 , mounting ears 15 are screwed to both sides of the handle 1, so as to facilitate the installation of the bevel cutter on an external cutting device.

[0038] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
