The upper end of the first screw 102b is connected to the second movable member 103. The operator drives the first screw 102b to rotate by rotating the rotation button 102c, thereby driving the second movable member 103 to move in the linear direction of the first screw 102b.

[0032] Furthermore, in this embodiment, the second movable member 103 includes a second block 103a connected to the first screw 102b, a guide roller 103c arranged on the second block 103a, and a guide block 300a connected to the guide roller 103c, and a movable clamp 300 is provided on the second block 103a.

[0033] In this embodiment, the movable clamping member 300 includes a movable block body 301 slidably connected to the guide block body 300a, a guide positioning block 302 arranged in the movable block body 301, a clamping rod 303 rotatably connected to the guide positioning block 302, and an elastic sheet 304 arranged in the movable block body 301 and the guide positioning block 302.

[0038] Operation process: The operator can use the first movable member 102 and the second movable member 103 to flexibly adjust the position of the tool, and when performing the feed operation, the operator can also use the movable clamp 300 to make fine adjustments, and the movable clamp 300 has a locking function, so that the tool will not be offset during operation.

[0039] When adjusting the tool position, the operator operates the movable guide rope 308, and the movable guide rope 308 drives the movable block 301 to move, and the clamping strip 305 on the movable block 301 is blocked by the inclined guide strip 306, and the guide strip 306 will "press down" the clamping strip 305, thereby driving the guide positioning block 302 to move downward, and the downward movement of the guide positioning block 302 will be restricted by the clamping rod 303, and at the same time press down the elastic sheet 304, and when the movable block 301 drives the clamping strip 305 After moving over the range of the guide bar 306, the elastic sheet 304 will push the guide positioning block 302 upward, and then the driving motor will reverse, driving the guide wheel to reverse, so that the moving block 301 moves forward, and when the moving block 301 moves forward, the clamping strip 305 is just stuck in the position between the two guide bars 306, and because the guide bars 306 are inclined, the continuous movement of the clamping strip 305 will drive the top block 103d to slide forward, thereby finely adjusting the tool extension distance. Example 2

[0040] Reference Figure 7 , this embodiment is different from the previous embodiment in that: further, a steering component 400 is provided between the first tool holder plate 201 and the top block body 103d. In this embodiment, the steering component 400 includes a rotation control main rod 401 rotatably connected to the top block body 103d, the rotation control main rod 401 extends in the horizontal direction, and a transverse connecting rod 402 is rotatably connected to the rotation control main rod 401, the transverse connecting rod 402 is horizontally arranged, but the angle between the transverse connecting rod 402 and the first pillar is 90°, and an open control ring 403 is also provided on the rotation control main rod 401, and the open control ring 403 is also horizontally arranged, a first motor 404 is provided at the rear end of the rotation control main rod 401, and a connecting rod 405 is provided between the motor shaft of the first motor 404 and the rotation control main rod 401, the first pillar is connected to the side wall of the connecting rod 405, and the end of the first pillar close to the connecting rod 405 is arc-shaped, while the end away from the first pillar is straight.

[0041] Preferably, a circular recessed groove for adjusting the steering component 400 is provided on the upper surface of the top block 103d.

[0042] Preferably, a moving part 406 is provided on the open control ring 403, and the moving part 406 can move in a circle along the open control ring 403 on the open control ring 403, a second motor 407 is provided on the rotation control main rod 401, and a first gear 408 is directly connected to the motor shaft of the second motor 407, and a second gear 409 meshing with the first gear 408 is provided on the transverse connecting rod 402, the transverse connecting rod 402 passes through one end of the first pillar and is fixed to the open control ring 403, and the other end is also fixed on the inner side of the second circular ring, and the length of the transverse connecting rod 402 is the diameter length of the open control ring 403, and then when the second motor 407 is started, the meshing relationship between the gears drives the rotation of the transverse connecting rod 402, thereby realizing the overall rotation of the open control ring 403 in the vertical direction, and in order to prevent the open control ring 403 from obstructing the first pillar when rotating, an opening is opened on the open control ring 403.

[0043] Furthermore, a slide rail is provided on the upper surface of the open control ring 403, and the slide rail is opened along the circle of the open control ring 403. In the present embodiment, the movable member 406 includes a support block 406a slidably connected to the slide rail, and the support block 406a extends outward and maintains a horizontal state.

The elastic connector 104 is a spring provided between the first tool holder plate 201 and the second tool holder plate 203. There are a plurality of springs, and a guide rod is also connected between the first tool holder plate 201 and the second tool holder plate 203, forming a ball hinge at the connection between the first tool holder plate 201 and the second tool holder plate 203 and the guide rod.

[0045] The rest of the structure is the same as that of Example 1.

[0046] Operation process: When adjusting the position state of the machine tool knife, the operator drives the first motor 404 by sending a starting electrical signal to the first motor 404. The first motor 404 drives the rotation of the rotation control main rod 401. The rotation control main rod 401 drives the open control ring 403 to perform a micro-angle rotation adjustment in the first longitudinal dimension through the transverse connecting rod 402. If another angle adjustment is required, the second motor 407 drives the rotation of the transverse connecting rod 402, and then the first gear 408 drives the rotation of the second gear 409. Because the second gear 409 is connected to the transverse connecting rod 402, it will drive the open control ring 403 to perform a micro-angle rotation adjustment in another longitudinal dimension.
