[0023] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: an adjustable tool holder, including a frame body 1, a groove 2 is opened on one side of the frame body 1, a plurality of limit grooves 3 are opened on the other side of the frame body 1, a clamping block 4 is arranged inside the frame body 1, a protrusion 5 is fixedly connected to the outer wall of the clamping block 4, the outer wall of the protrusion 5 is slidably connected to the inner wall of one of the limit grooves 3, a fixing block 6 is fixedly connected inside the frame body 1, a threaded rod 7 is threadedly connected inside the fixing block 6, a rotating handle 20 is fixedly connected to one end of the threaded rod 7, and a clamping block 2 8 is rotatably connected to the outer wall of the threaded rod 7, a rotating block 21 is rotatably connected to the outer wall of the rotating block 21, one side of the outer wall of the rotating block 21 abuts against the outer wall of the protrusion 5, a protrusion 2 9 is fixedly connected to the lower surface of the frame body 1, a shell 12 is arranged on the lower surface of the frame body 1, and a fixing component is arranged inside the shell 12.

[0024] Specifically, the position of the clamping block 4 can be flexibly adjusted by inserting the protrusion 5 connected to the clamping block 4 into the limiting groove 3 at different positions set inside the frame 1, so that the position of the tool can be adjusted so that the tool can be aligned with the workpiece position, and then the clamping block 4 and the protrusion 5 are fixed inside the frame 1 by rotating the rotating block 21, thereby reducing the operating difficulty and improving the work efficiency. By rotating the rotating handle 20 to rotate the threaded rod 7, the clamping block 2 8 can be pressed tightly against the outer wall of the tool to prevent the tool from moving, thereby improving the stability of the tool holder. This height adjustment method has low operating difficulty, saves time, and improves the work efficiency.

[0025] Reference Figure 1 and Figure 2 The fixing component includes a strong spring 11, one end of the strong spring 11 is fixedly connected to the inner wall of the shell 12, and the other end of the strong spring 11 is fixedly connected to a pad 10, the outer wall of the pad 10 abuts against the lower surface of the protrusion 29, and the outer wall of the protrusion 29 is rotatably connected to a rotating block 17, the inner wall of the rotating handle 20 is fixedly connected to a hinge seat 14, and a hydraulic rod 15 is rotatably connected inside the hinge seat 14, and a fixed shaft 16 is fixedly connected to the output end of the hydraulic rod 15, and the outer wall of the fixed shaft 16 is rotatably connected to the inside of the rotating block 17, and the rotating block 17 is rotatably connected to a connecting shaft 18, and one side of the outer wall of the connecting shaft 18 is fixedly connected to the inner wall of the shell 12, and a plurality of limit grooves 3 are linearly distributed from bottom to bottom inside the frame 1, and a sliding block 19 is fixedly connected to the lower surface of the shell 12, and a groove 2 13 is opened inside the shell 12, and the outer wall of the rotating block 17 is slidably connected inside the groove 2 13.

[0026] Specifically, the hydraulic rod 15 drives the rotating block 17 connected to the fixed shaft 16 to rotate, so that the frame 1 can be tilted, and then the tool can be tilted to meet different processing requirements, thereby achieving the effect of improving the flexibility of the device. When the frame 1 is tilted, the strong spring 11 enables the pad 10 to always support the frame 1 connected to the protrusion 2 9 to prevent the tilted frame 1 from shaking, thereby achieving the effect of improving the stability of the tool holder. The sliding block 19 on the lower surface of the outer shell 12 can make the frame 1 slide more stably in the track of the external equipment, thereby facilitating the movement of the frame 1.

[0027] Working principle: When the adjustable tool holder is needed, first, the position of the clamping block 4 can be flexibly adjusted by placing the protruding block 5 connected to the clamping block 4 into the appropriate limiting groove 3, thereby achieving the effect of changing the position of the cutter head and avoiding the trouble of constant adjustment of the traditional gasket. After the clamping block 4 is positioned, the cutter head is placed into the frame 1 from the groove 2, and then the rotating handle 20 is turned to make the clamping block 2 8 connected to the threaded rod 7 press the outer wall of the cutter head to achieve the effect of firmly fixing the position of the cutter head. The rotating block 21 on the outer wall of the rotating frame 1 can limit the clamping block 4 and the protruding block 5 inside the frame 1, thereby reducing the difficulty of operation. The rotating block 21 is connected to the frame 1 by bolts. After locking the position, the bolts can be tightened to ensure that the rotating block 21 is not loose. , rotating the rotating handle 20 can make the threaded rod 7 press the clamping block 2 8 against the outer wall of the cutter head under the restriction of the fixed block 6, so as to increase the stability of the tool holder. The hydraulic rod 15 arranged inside the shell 12 can drive the rotating block 17 to rotate so as to tilt the frame 1, which can meet the processing requirements of different workpieces and increase the flexibility of the tool holder. Then, a pad 10 is arranged on the lower surface of the protrusion 2 9, and the force generated by the reset of the strong spring 11 makes the pad 10 close to the outer wall of the protrusion 2 9, so as to achieve the effect of supporting the inclined frame 1, avoiding the angle of the inclined frame 1 from changing during the processing, providing support for the frame 1, and improving the work efficiency at the same time. The sliding block 19 arranged on the lower surface of the shell 12 enables the frame 1 to slide stably on the track set by the equipment, and adjust the processing depth according to the needs.
