[0007] By adopting the above technical solution, the two cylinders can drive the two moving blocks to slide up and down on the inner walls of the two through slots, which can be used to move the position of the blade body, thereby facilitating the cutting of materials of different sizes and thicknesses.

[0008] In a preferred embodiment, a fixing plate is installed on the top of the connecting frame, and the outer wall of the fixing plate is fixedly connected to the outside of the cylinder.

[0009] By adopting the above technical solution, the fixed plate can be used to position the cylinder, ensuring that the cylinder can be stably set above the connecting frame and that it will not easily shake during operation.

[0010] In a preferred embodiment, the inner wall of the slider is provided with a track groove, and the guide rail is adapted to be disposed on the inner wall of the track groove.

[0011] By adopting the above technical solution, the lifting plate can use the slider to drive the tool holder to slide above the two guide rails, thereby moving the tool holder to a new position to achieve tool changing.

[0012] In a preferred embodiment, a stepper motor is mounted on the outer side of the moving block, and the output shaft of the stepper motor is fixedly connected to the blade body.

[0013] By adopting the above technical solution, a stepper motor can be driven to rotate the blade body, thereby realizing the cutting operation of materials.

[0014] In a preferred embodiment, the fastening plate is disposed on the outside of the towing frame, and the top of the side plate is provided with a clearance groove, and the fastening plate is rotatably connected to the inner wall of the clearance groove.

[0015] By adopting the above technical solution, the towing frame can be fastened and locked using the fastening plate, ensuring that it will not easily fall out of position, thus improving stability. Furthermore, the fastening plate is designed with a clearance groove so that it will not interfere with the side plate when rotating.

[0016] In a preferred embodiment, the size of the movable block is adapted to the inner wall size of the through groove.

[0017] By adopting the above technical solution, the moving block will not swing left or right when it moves up and down on the inner wall of the through groove, thus ensuring stability.

[0018] The beneficial effects of this application are: This tool changing device uses a drag frame to pull a slider at the bottom of the tool holder to slide outside the guide rail, thereby moving the tool holder and tool body to different positions to achieve tool changing. This improves tool changing efficiency, reduces manual intervention, enhances the safety of the tool changing process, reduces the cost of the tool changing device, and improves versatility.

[0023] See Figure 1 and Figure 2 The adjustment mechanism includes two through slots 4, with movable blocks 5 slidably connected to the inner walls of both through slots 4. A blade body 6 is rotatably connected between the two movable blocks 5. The output shaft of a cylinder 7 is fixedly connected to the top of the two movable blocks 5, so that driving the two cylinders 7 can drive the two movable blocks 5 to slide up and down on the inner walls of the two through slots 4, thereby moving the position of the blade body 6, thus facilitating the cutting of materials of different sizes and thicknesses.

[0024] See Figure 1 A fixing plate 8 is installed on the top of the connecting frame 3. The outer wall of the fixing plate 8 is fixedly connected to the outside of the cylinder 7, so that the fixing plate 8 can be used to position the cylinder 7, ensuring that the cylinder 7 can be stably set above the connecting frame 3 and that it will not easily shake during operation.

[0025] See Figure 1 - Figure 3The inner wall of the slider 10 is provided with a track groove, and the guide rail 9 is adapted to be set on the inner wall of the track groove, so that the lifting plate 2 can use the slider 10 to drive the tool holder 1 to slide above the two guide rails 9, thereby moving the tool holder 1 to a new position to realize tool changing.

[0026] See Figure 1 and Figure 4 A stepper motor 19 is installed on the outside of the moving block 5. The output shaft of the stepper motor 19 is fixedly connected to the blade body 6, so that the stepper motor 19 can drive the blade body 6 to rotate, thereby realizing the cutting operation of the material.

[0027] See Figure 2 and Figure 4 The fastening plate 17 is disposed on the outside of the towing frame 14, and the top of the side plate 15 is provided with a relief groove 18.
