For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following is an explanation of the embodiments of the present utility model based on the overall structure of the present utility model.

[0022] See also Figure 1-4A detachable trimming knife for a trimming machine comprises a mounting seat 1, a mounting groove 2 is provided on the top of the mounting seat 1, a blade 3 is installed inside the mounting groove 2, arc grooves 301 are provided on the rear end surfaces of both ends of the blade 3, pressing mechanisms 4 are installed on the front end surfaces of both ends of the mounting seat 1, the rear end surface of the mounting groove 2 is connected with a connecting groove 5, and the two ends of the connecting groove 5 are connected with through grooves 6 that penetrate through the two ends of the mounting seat 1, and a limiting mechanism 7 is installed inside the through groove 6.

[0023] like Figure 1-4 As shown, the pressing mechanism 4 includes a first mounting plate 401 installed at the bottom of the front end surface of both ends of the mounting seat 1, and a second mounting plate 402 fixed to the two ends of the mounting seat 1 is arranged on the top of the first mounting plate 401, and a pressing block 403 is rotatably connected to the top center of the second mounting plate 402, and mounting holes 404 that penetrate to the bottom of the first mounting plate 401 are opened at the front and rear ends of the top of the second mounting plate 402. When installing the blade 3, the pressing block 403 is first rotated to the long side end parallel to the mounting groove 2, and then the blade 3 is installed inside the mounting groove 2, and then the long side end of the pressing block 403 is rotated to be perpendicular to the mounting groove 2. Because the first mounting plate 401 and the second mounting plate 402 can be made of elastic plates, the second mounting plate 402 can be tightly squeezed toward the first mounting plate 401 by threading the screw in the mounting hole 404, so that the pressing block 403 tightly presses the blade 3.

[0024] like Figure 1-4 As shown, the limiting mechanism 7 includes a fixing block 701 installed at the front and rear ends of the side of the through slot 6 away from the blade 3, one end of the fixing block 701 is connected to a first spring 702, the other end of the first spring 702 is connected to a connecting block 703, and the opposite end of the connecting block 703 is installed with a limiting seat 704 that can fix the position of the blade 3. When installing blades 3 of different sizes, when installing the blade 3 into the installation slot 2, the blade 3 can be fixed by squeezing the limiting seat 704 toward the blade 3.

[0025] like Figure 1-4 As shown, the limiting seat 704 includes a limiting plate 7041 fixed at the opposite end of the connecting block 703, and the limiting plate 7041 is provided with grooves 7042 equidistantly at one end facing the blade 3, and a second spring 7043 is installed inside the groove 7042, and the other end of the second spring 7043 is connected to a rolling seat 7044. In the process of squeezing the limiting plate 7041 toward the blade 3, the rolling seat 7044 set therein will abut against the position corresponding to the arc groove 301, and then compress the second spring 7043 to have a certain clamping force on the blade 3, and the elastic expansion and contraction of the second spring 7043 enables the rolling seat 7044 to clamp blades 3 of different sizes.

[0026] like Figure 1-4As shown, the side of the limiting plate 7041 away from the blade 3 is in an arc structure, and the setting of the limiting plate 7041 away from the blade 3 is in an arc structure, which facilitates the movable plate 12 to squeeze the limiting plate 7041 and move toward the blade 3.

[0027] like Figure 1-4 As shown, connecting seats 8 are installed on the rear end faces of both ends of the mounting seat 1, and the rear end face of the connecting seat 8 is provided with a third spring 9 in a circumferential array, and the rear end of the third spring 9 is connected to a connecting plate 10, and the front end face of the connecting plate 10 is connected to a connecting rod 11 that is movable and penetrates the connecting seat 8, and the front end face of the connecting rod 11 is connected to a movable plate 12. When it is necessary to clamp the blade 3, the staff first moves the extended end of the connecting plate 10 toward the rear side so that the movable plate 12 no longer contacts the arc structure of the limiting plate 7041. At this time, the limiting seat 704 is moved in a direction away from the blade 3 by the rebound force of the first spring 702. At this time, the blade 3 can be smoothly inserted into the mounting groove 2. After the blade 3 is placed in, the extended end of the connecting plate 10 is released, and the movable plate 12 is reset by the elastic force of the third spring 9. While the movable plate 12 is reset, it will squeeze the limiting plate 7041, so that the rolling seat 7044 clamps the blade 3.

[0028] Working principle: When installing the blade 3, first rotate the pressure block 403 until the long side end is parallel to the installation slot 2, then the staff moves the extended end of the connecting plate 10 toward the rear side so that the movable plate 12 is no longer in contact with the arc structure of the limiting plate 7041. At this time, the limiting seat 704 moves in a direction away from the blade 3 through the rebound force of the first spring 702. At this time, the blade 3 can be smoothly inserted into the installation slot 2. After the blade 3 is inserted, the extended end of the connecting plate 10 is released, and the elastic force of the third spring 9 makes the limiting seat 704 move away from the blade 3. The movable plate 12 is reset, and at the same time, the movable plate 12 will squeeze the limit plate 7041, so that the rolling seat 7044 clamps the blade 3, and then the long side end of the pressing block 403 is rotated to be perpendicular to the mounting groove 2. Because the first mounting plate 401 and the second mounting plate 402 can be made of elastic plates, the second mounting plate 402 can be tightly squeezed toward the first mounting plate 401 by a screw threaded connection inside the mounting hole 404, so that the pressing block 403 tightly presses the blade 3.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
