[0012] In the figure, 1, fixed seat; 2, blade body; 3, mounting seat; 4, positioning assembly; 5, mounting groove; 6, positioning seat; 7, positioning hole; 8, positioning rod; 9, connecting spring; 10, pull rod; 11, sliding part; 12, positioning groove; 13, fixing column. DETAILED DESCRIPTION
[0013] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
[0014] like Figure 1 , Figure 2 As shown, the replaceable blade comprises a fixing seat 1 and a blade body 2. The blade body 2 can be a long strip blade of different types. The blade body 2 is fixedly mounted on the fixing seat 1 through a mounting seat 3. A slot for mounting the blade body 2 is provided at the front end of the mounting seat 3. A positioning component 4 for positioning the blade body 2 is provided on the mounting seat 3. A mounting slot 5 for mounting the positioning component 4 is provided on the mounting seat 3. A positioning seat 6 is provided at the front end of the mounting seat 3 and at a position relative to the blade body 2. The positioning seat 6 restricts the blade within the slot, thereby improving the blade For stability in use, a positioning hole 7 cooperating with the positioning component 4 is provided on the blade body 2, and the positioning component 4 includes a positioning rod 8 and a connecting spring 9. One end of the positioning rod 8 extends into the mounting groove 5 and cooperates with the positioning hole 7, and the other end of the positioning rod 8 extends out of the mounting groove 5 and is connected with a pull rod 10. A sliding portion 11 is provided on the positioning rod 8, and the connecting spring 9 is arranged between the mounting seat 3 and the sliding portion 11. The positioning rod 8 slides up and down in the mounting groove 5 under the action of the connecting spring 9, and a positioning groove 12 is also provided on the mounting seat 3 for the positioning rod 8 to partially extend into.
[0015] To elaborate further, when the blade needs to be disassembled after being worn out due to long-term use, the pull rod 10 is pulled to move the sliding part 11 upward, and the positioning rod 8 is driven to move upward at the same time. The positioning rod 8 releases the positioning of the blade positioning hole 7, and different types of blades can be replaced for processing. When installing the blade, first pull the pull rod 10 to move the sliding part 11 upward, and the positioning rod 8 is driven to move upward at the same time. The connecting spring 9 is compressed. When the blade is installed along the slot, the pull rod 10 is then released, the connecting spring 9 rebounds, and the positioning rod 8 passes through the positioning hole 7 of the blade and extends to the positioning groove 12 of the mounting seat 3.
[0016] To be more specific, the mounting base 3 is fixedly mounted on the fixing base 1 via a plurality of fixing columns 13 , wherein the fixing columns 13 are respectively arranged horizontally and vertically.
[0017] To be more specific, a through hole is provided on the mounting seat 3 at a position relative to the positioning slot 12 for facilitating the adjustment of the positioning assembly 4 .
[0018] To be more specific, the positioning seat 6 is fixedly mounted on the mounting seat 3 by fixing bolts.
[0019] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
[0020] Although the terms such as the fixing seat 1, the blade body 2, the mounting seat 3, the positioning assembly 4, the mounting groove 5, the positioning seat 6, the positioning hole 7, the positioning rod 8, the connecting spring 9, the pull rod 10, the sliding part 11, the positioning groove 12, the fixing column 13, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only for more convenient description and explanation of the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
