[0019] See also Figure 1-4 The utility model provides a technical solution: a sharp knife with a replaceable handle, comprising a handle 2 and a blade 1, wherein the blade 1 is provided in the middle of the two handles 2, and the handles 2 and the blade 1 are symmetrically provided with mounting holes 3 on one side of the outer wall, and the inner walls of the two mounting holes 3 are slidably connected with fixing bolts 4, and the outer walls of one side of the two handles 2 are fixedly connected with protrusions, and the two protrusions are both penetrated and opened into the handle 2 on the other side;

[0020] A threaded hole 5 is formed through the outer wall of one end of the two protrusions, one end of the threaded hole 5 extends to the outside of the handle 2 and is threadedly connected to a fixing screw 6, one end of the fixing screw 6 extends to the outside of the handle 2 and is fixedly connected to a fixing block 7, and a sliding cavity is formed through the inside of the two handles 2 on one side of the mounting hole 3, and the inner walls of several sliding cavities are slidably connected to limit blocks 8;

[0021] One ends of several limit blocks 8 extend through the holes to the corresponding fixing bolts 4, and movable grooves are opened on the outer walls of both sides of the two knife handles 2 relative to the position of the sliding cavity. One ends of several movable grooves extend through the corresponding sliding cavity and are slidably connected to the limit buckles 9, and the outer walls of one ends of several limit buckles 9 are against the corresponding limit blocks 8.

[0022] Among them, the inner wall of one side of several sliding cavities relative to the position of the limiting buckle 9 is penetrated by limiting holes 10, and one end of several limiting buckles 9 extends into the corresponding limiting holes 10, so as to use the limiting holes 10 to limit the limiting buckle 9.

[0023] Among them, one end of the two limiting buckles 9 on the same side both extend out of the corresponding moving grooves and are fixedly connected to the mounting block 11 , so that the limiting buckles 9 can be limited by using the mounting block 11 .

[0024] Among them, the outer walls of one end of several limit blocks 8 are fixedly connected with springs 13, and the other ends of several springs 13 are fixedly connected to the corresponding tool handles 2, so that the limit blocks 8 can be driven to move by the springs 13.

[0026] Specifically, when using the utility model, the limiting buckle 9 is pressed inwardly to separate the limiting buckle 9 from the knife handle 2, and the mounting block 11 is moved outward. The mounting block 11 drives the limiting buckle 9 to move out of the knife handle 2, and the fixing screw 6 is driven out of the threaded hole 5 through the fixing block 7. The spring 13 pushes the fixing block 7 to move out of the fixing bolt 4, and the fixing bolt 4 is moved out of the mounting hole 3. The old knife handle 2 is separated from the blade 1, and the new knife handle 2 is abutted against the blade 1, and the fixing bolt 4 is inserted into the mounting hole 3.
