The inner surface of the tool holder housing 1 is rotatably connected to the rotating block 201, the outer surface of the rotating block 201 is provided with a snap-fitting groove 202, the inner surface of the rotating block 201 is fixedly connected to the shutter 203, the inner surface of the tool holder housing 1 is fixedly connected to the tension spring 204, one end of the tension spring 204 is fixedly connected to the sliding rod 205, and the outer surface of the sliding rod 205 is fixedly connected to the snap-fitting block 206. Through the arrangement of the rotating block 201, the snap-fitting groove 202, the shutter 203, the tension spring 204, the sliding rod 205 and the snap-fitting block 206, during use, the shutter 203 can be opened. The size of the gap at the center can be changed by rotation. Multiple shutters 203 can clamp different parts of the tool handle respectively, so that each clamping part fits with the tool handle, increasing the clamping accuracy. The rotating block 201 is fixed to the outside of the shutter 203 for rotating the shutter 203. The engaging groove 202 on the outside of the rotating block 201 increases the friction to facilitate rotation. The engaging block 206 is connected to the tool holder housing 1 through the sliding rod 205 and is constrained by the tension spring 204. After adjusting the shutter 203, the tension spring 204 drives the engaging block 206 to make it close to the engaging groove 202 on the rotating block 201 to limit its rotation, thereby fixing the current engaging gap of the shutter 203. Since different shutters 203 can clamp different areas on the tool handle, it is suitable for clamping tool handles of different shapes and sizes in different areas.

[0023] Furthermore, the engaging grooves 202 are distributed in a ring shape on the outer surface of the rotating block 201, the rotating blocks 201 are distributed evenly, the shutters 203 are distributed evenly, the engaging grooves 202 are distributed in a ring shape on the periphery of the rotating block 201, and part of the engaging grooves 202 are exposed when the rotating block 201 is rotated to any angle.

After adjusting the shutter 203, the tension spring 204 drives the engaging block 206 to make it close to the engaging groove 202 on the rotating block 201 to limit its rotation.

[0025] Furthermore, the synchronous locking mechanism 3 includes a fixed buckle 301, a limiting protrusion 302, a movable buckle 303, a limiting groove 304, a mounting base 305, a locking latch 306 and a handle 307. The top surface of the tool holder housing 1 is fixedly connected with the fixed buckle 301, the outer surface of the fixed buckle 301 is provided with a limiting protrusion 302, the top surface of the tool holder housing 1 is slidably connected with the movable buckle 303, the inner surface of the movable buckle 303 is provided with a limiting groove 304, the top surface of the fixed buckle 301 is fixedly connected with the mounting base 305, the inner surface of the mounting base 305 is slidably connected with the locking latch 306, and the outer surface of the locking latch 306 is fixedly connected with the handle 307. The locking cam 306 of the handle 307 is adjusted to lock the positions of the two mounting bases 305. The locking cam 306 of the handle 307 is adjusted to lock the positions of the two mounting bases 305.

[0027] Furthermore, the top surface of the movable buckle 303 is fixedly connected to the mounting base 305, and the outer surface of the mounting base 305 is slidably connected to the handle 307. Since the latch 306 and the handle 307 are respectively located on both sides, rotating only one side will be blocked by the other side. Both hands must be used to rotate the handle 307 at the same time to rotate the latch 306.

[0028] Working principle: A high-precision tool bar clamping device. During use, the shutter 203 can change the size of the gap at the center by rotating. Multiple shutters 203 can clamp different parts of the tool handle respectively. The rotating block 201 is fixed to the outside of the shutter 203 for rotating the shutter 203. The engaging groove 202 on the outside of the rotating block 201 increases the friction force for easy rotation. The engaging block 206 is connected to the tool holder housing 1 through the sliding rod 205 and is constrained by the tension spring 204. After adjusting the shutter 203, the tension spring 204 drives the engaging block 206 to make it close to the rotating block The locking groove 202 on 201 limits its rotation. The fixed buckle 301 and the movable buckle 303 are hollow inside for placing the knife rod. When the fixed buckle 301 and the movable buckle 303 are flush, the mounting base 305 is in the same plane. The internal locking latch 306 is adjusted by the handle 307 to connect the mounting bases 305 on both sides to lock the position of the fixed buckle 301 and the movable buckle 303. At the same time, the handle 307 can be turned to rotate the locking latch 306 to unlock or close the locking latch 306 to limit the movement of the buckle, thus completing a high-precision knife rod clamping device.
