A mounting groove is opened at the bottom of the limiting piece 8. A magnet 9 is fixedly mounted in the mounting groove. The limiting piece 8 and the magnet 9 abut against the top of the connecting plate 71. A set of handle grooves 10 are opened on both sides of the U-shaped plate 2. At least two sets of mounting holes 11 are opened through the mounting plate 1.

[0027] The positioning mechanism 6 is set on the mounting sleeve 3. The positioning mechanism 6 includes a connecting piece 61, a positioning rod 62 and a collar 63. The outer surface of the mounting sleeve 3 is provided with a connecting piece 61 that fits therein. The outer surface of the mounting column 4 is provided with two sets of positioning grooves. Two sets of positioning rods 62 are fixedly installed on the side of the connecting piece 61 that is close to the mounting sleeve 3. Both sets of positioning rods 62 pass through the mounting sleeve 3 and are inserted into the corresponding positioning grooves. The top of the connecting piece 61 is fixedly installed with a collar 63.

[0028] The positioning mechanism 6 also includes a fixing rod 64, an anti-detachment plate 65, a first spring 66, and a pull ring 67. The fixing rod 64 is fixedly installed on the outer surface of the mounting sleeve 3. An anti-detachment plate 65 is fixedly installed at one end of the fixing rod 64. The first spring 66 is sleeved on the fixing rod 64. The collar 63 is movably sleeved on the fixing rod 64. The two ends of the first spring 66 are fixedly connected to the collar 63 and the anti-detachment plate 65, respectively. A pull ring 67 is fixedly installed on the side of the connecting piece 61 facing away from the mounting sleeve 3. By using the positioning mechanism 6 on the mounting sleeve 3, the tool head 5 can be disassembled and assembled simply by pulling the pull ring 67 to insert and remove the positioning rod 62 onto the mounting post 4. The operation is simple and the disassembly and assembly are quick. This solves the problem that in some existing tools, the tool head is disassembled and assembled by bolts, which requires the use of tools to turn the bolts and manually tighten the tool, which is time-consuming, labor-intensive, and inefficient.

The two ends of the second spring 76 are fixedly connected to the connecting plate 71 and the sleeve 74, respectively. Through the adjustment mechanism 7, the cutter head 5 can be changed to the required angle according to the processing needs. At the same time, under the action of the limiting plate 8 and the magnet 9, the adjustment mechanism 7 can be locked to ensure the stability of the cutter and the effectiveness of the device, which is conducive to the promotion and use of the device.

[0030] A cutting device comprising a cutting tool according to any one of the foregoing claims.

[0031] Working principle: When disassembling or assembling the cutter head 5, pulling the pull ring 67 moves the connecting piece 61 outward. The collar 63 slides on the fixing rod 64 and compresses the first spring 66. The connecting piece 61, along with the two sets of positioning rods 62, is pulled outward until it disengages from the positioning groove on the mounting post 4. Then, the mounting post 4 can be removed from the mounting sleeve 3 and the cutter head 5 can be replaced. After replacement, releasing the pull ring 67 causes the two sets of positioning rods 62 to reset and reposition the mounting post 4 under the rebound action of the first spring 66. When adjusting the angle of the cutter head 5... When the limiting plate 8 is rotated so that it no longer limits the connecting plate 71, the mounting sleeve 3 is lifted and the connecting plate 71 is raised through the connecting post 72. The various inserts 73 on the connecting plate 71 are disengaged from their respective positioning holes, and the second spring 76 is compressed. At this time, the mounting sleeve 3 can be rotated to rotate the cutter head 5 to the required angle and then released. Under the rebound action of the second spring 76, the various inserts 73 are reset to be repositioned and the limiting plate 8 is reset, so that the magnet 9 is attracted to the connecting plate 71 and limits the connecting plate 71.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
