Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0024] Please refer to the attached Figure 1-Figure 5 As shown, the utility model provides a technical solution: a special-shaped turning tool, comprising a blade body 10 and a blade head 20, characterized in that one end of the blade body 10 is fixedly connected with a diamond-shaped connecting block 106, a clamping hole 201 is provided on the blade head 20, and the clamping hole 201 is slidably engaged with the diamond-shaped connecting block 106, and a first sliding hole 104 and two second sliding holes 202 are respectively provided on the blade body 10 and the blade head 20, and a fixing mechanism is provided in the first sliding hole 104 and the two second sliding holes 202, and the fixing mechanism includes two clamping blocks 14 slidably installed in the first sliding hole 104 and the two second sliding holes 202, and two fixing blocks 13 are fixedly connected to the sides of the two clamping blocks 14 close to each other, and the two ends of the blade head 20 are conveniently fixed by sliding the two clamping blocks 14 in the two second sliding holes 202 respectively.

[0025] In this embodiment, an L-shaped sliding hole 101 is provided in the blade body 10, and the L-shaped sliding hole 101 consists of a vertical end and a horizontal end. The horizontal end of the L-shaped sliding hole 101 extends into and is connected with the diamond-shaped connecting block 106. A sliding rod 11 is slidably installed at the horizontal end of the L-shaped sliding hole 101. An open groove 111 is provided at one end of the sliding rod 11. Two transmission rods 12 are respectively hinged between the two ends of the open groove 111 and the two fixed blocks 13. By moving the sliding rod 11, the sliding rod 11 is driven by the two transmission rods 12 to pull or push the two blocking blocks 14 to move in the first sliding hole 104 and the two second sliding holes 202.

[0026] In this embodiment, the vertical end of the L-shaped sliding hole 101 is connected to the outer side of the blade body 10, and the other end of the sliding rod 11 is fixedly connected to the push rod 15. The push rod 15 is slidably installed in the vertical end of the L-shaped sliding hole 101 and extends out of the outer side of the blade body 10. The push rod 15 is provided to facilitate the movement of the sliding rod 11.

[0027] In this embodiment, a plurality of grooves 151 are evenly formed on the upper end of the push rod 15 to increase the friction between the finger and the upper end of the push rod 15 .

[0028] In this embodiment, an expansion hole 103 is opened at the connection between the L-shaped sliding hole 101 and the first sliding hole 104. When the two transmission rods 12 are completely retracted into the open groove 111, the two transmission rods 12 are prevented from touching the corners at the connection between the L-shaped sliding hole 101 and the first sliding hole 104, resulting in incomplete retraction.

[0029] In this embodiment, a plurality of first limiting holes 105 and a plurality of second limiting holes 203 are respectively provided in the first sliding hole 104 and the two second sliding holes 202, and a plurality of limiting blocks 141 are evenly fixedly installed on the outer surfaces of the two clamping blocks 14, and the plurality of limiting blocks 141 are respectively slidably installed in the plurality of first limiting holes 105 and the second limiting holes 203, and the two clamping blocks 14 are limited by the plurality of limiting blocks 141 slidingly engaging in the plurality of first limiting holes 105 and the second limiting holes 203.

[0030] In this embodiment, a circular hole 102 is opened on one side of the horizontal end of the L-shaped sliding hole 101, and the other end of the circular hole 102 is connected to the outer side of the blade body 10. A threaded rod 16 is installed in the inner thread of the circular hole 102, and a knob 17 is fixedly connected to the end of the threaded rod 16 close to the outer side of the blade body 10. By rotating the knob 17, the threaded rod 16 moves in the circular hole 102 close to the sliding rod 11, thereby fixing the position of the sliding rod 11.

[0031] In this embodiment, two frame-shaped blades 204 are fixedly connected to the outer surfaces of both ends of the blade head 20 .

[0032] Specifically, when the cutter head 10 on the blade body 10 is disassembled, the knob 17 is first turned to make the threaded rod 16 rotate in the round hole 102 away from the outer surface of the slide rod 11, thereby releasing the fixation of the slide rod 11. Then, the push rod 15 is pulled to move in the vertical end of the L-shaped slide hole 101, so that the slide rod 11 pulls the two transmission rods 12, driving the two clamping blocks 14 to move closer to each other in the first slide hole 104 and the two second slide holes 202. When the two transmission rods 12 shrink into the open groove 111, the two clamping blocks 14 are completely separated from the two second slide holes 202, and the cutter head 20 is pulled to make the clamping hole 201 slide away from the diamond-shaped connecting block 106, so that the cutter head 20 can be removed from the blade body 10 without the aid of additional tools.

[0033] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
