[0021] The present invention provides a cutting tool, including a base plate 101, a blade 102, a mounting mechanism, a pressing assembly, a bracket 103, a screw 104, a pressing plate 105 and two sliding rods 106. The mounting mechanism includes a support member 107, a box body 108, a holding assembly, two sliding members, a plurality of springs 109, two limiting rods 110, two sliding blocks 111, two elastic telescopic rods 112 and a supporting block 113. The holding assembly includes a force-applying member 114, a disc 115, two holding rods 116 and two force-bearing blocks 117. The sliding member includes a slide plate 118 and a connecting block 119. The pressing assembly includes two supporting rods 120 and a pressing block 121. The above-mentioned solution solves the technical problem in the prior art that the cutting tool is fixedly connected to the movable shaft and the blade 102 is fixedly connected to the cutting tool, which makes it inconvenient to replace the blade 102 after the blade 102 becomes blunt, thereby affecting the cutting effect.

[0022] According to this specific embodiment, scale lines are provided on the bottom plate 101 . The paper to be cut is placed on the bottom plate 101 , and the paper is moved to a specified position based on the scale lines, thereby improving the cutting accuracy.

[0023] Among them, the support member 107 is fixedly connected to the bottom plate 101, the box body 108 is fixedly connected to the support member 107, the support member 107 has a guide groove 122, a groove 123, two through holes 124 and two mounting grooves 125, the two sliders 111 are respectively placed in the corresponding mounting grooves 125, the two ends of the elastic telescopic rod 112 are respectively connected to the corresponding sliders 111 and the support block 113, the blade 102 is arranged on the support block 113, the slider 111 has a limiting groove 126, the sliding member and The groove 123 is slidably connected, one end of the limit rod 110 is fixedly connected to the corresponding sliding member, the other end of the limit rod 110 passes through the corresponding through hole 124 and is placed in the corresponding limit groove 126, the abutting component drives the two sliding members to move, the pressing component drives the support block 113 to move, and the two ends of the spring 109 are respectively connected to the corresponding sliding member and the support member 107. When in use, the paper to be cut is placed on the bottom plate 101, and the paper is moved to the specified position based on the scale line. The pressing assembly is then pressed, and the pressing assembly drives the support block 113 to move downward, and the support block 113 drives the blade 102 to move downward until cutting is performed. The elastic telescopic rod 112 is used to drive the blade 102 to reset. After the blade 102 becomes blunt, the two sliding members are driven toward each other by the abutting assembly, thereby driving the two limiting rods 110 to slide out of the corresponding limiting grooves 126 respectively, and then the two sliders 111 are taken out to disassemble the blade 102, and then a new blade 102 is put on. The two sliders 111 are aligned with the two mounting grooves 125, and the abutting assembly is released. At this time, the spring 109 is reset to drive the corresponding slider to move. At this time, the two sliders move relative to each other, which can drive the two limit rods 110 to be inserted into the corresponding limit grooves 126 respectively, and the installation can be completed. In this way, the technical problem in the prior art that the cutting tool is fixedly connected to the movable shaft and the blade 102 is fixedly connected to the cutting tool is solved, which makes it inconvenient to replace the blade 102 after it becomes blunt, thereby affecting the cutting effect.

[0024] Secondly, the two force blocks 117 are respectively fixedly connected to the corresponding sliding members, and the force blocks 117 have a force groove 127. The force-applying member 114 is fixedly connected to the box body 108, and the disc 115 is fixedly connected to the force-applying member 114. One end of the two supporting rods 116 is fixedly connected to the disc 115, and the other ends of the two supporting rods 116 are respectively placed in the corresponding force grooves 127. The force-applying member 114 is rotated, and the force-applying member 114 drives the disc 115 to move. The disc 115 drives the two supporting rods 116 to slide in the corresponding force grooves 127, which can drive the two force blocks 117 to move and then drive the two sliding members to move.

[0025] At the same time, the connecting block 119 is arranged between the corresponding force-bearing block 117 and the corresponding slide 118 . When the force-bearing block 117 moves, the corresponding slide 118 is driven to move by the corresponding connecting block 119 .

[0026] In addition, the two support rods 120 are both slidably connected to the support member 107, and the pressing block 121 is fixedly connected to the two support rods 120. Pressing the pressing block 121 drives the two support rods 120 to move, thereby driving the support block 113 to move.

[0027] Again, the bracket 103 is slidably connected to the base plate 101, one end of the sliding rod 106 passes through the bracket 103 and is fixedly connected to the pressure plate 105, and the screw 104 is used to drive the pressure plate 105 to move. By sliding the bracket 103 to a specified position and then twisting the screw 104, the screw 104 drives the pressure plate 105 to move downward to press the paper to prevent the paper from shifting or warping during cutting.

[0028] When using the cutting tool of the present invention, the paper to be cut is placed on the bottom plate 101, and the paper is moved to the specified position based on the scale line, and then the pressing component is pressed, and the pressing component drives the support block 113 to move downward, and the support block 113 drives the blade 102 to move downward until cutting is performed. The elastic telescopic rod 112 is used to drive the blade 102 to reset. After the blade 102 becomes blunt, the two sliding members are driven to move toward each other through the supporting assembly, thereby driving the two limiting rods 110 to slide out of the corresponding limiting grooves 126 respectively, and then the two sliders 111 are moved downward. The blade 102 can be disassembled by taking it out, and then the two sliders 111 on the new blade 102 are aligned with the two installation grooves 125, and the abutting assembly is released. At this time, the spring 109 is reset to drive the corresponding sliding member to move. At this time, the two sliding members move relative to each other, which can drive the two limit rods 110 to be inserted into the corresponding limit grooves 126 respectively, and the installation can be completed. In this way, the technical problem in the prior art that the cutting tool is fixedly connected to the movable shaft and the blade 102 is fixedly connected to the cutting tool is solved, which makes it inconvenient to replace the blade 102 after the blade 102 becomes blunt, thereby affecting the cutting effect.

[0029] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the utility model.
