[0032] As shown in the embodiment of the present disclosure, Figure 3As shown, the telescopic positioning pin 7 is a cylindrical rod and can slide forward and backward in the circular hole on the front side outer wall of the tool support cylinder 4. When the adjusting bracket 5 slides to the last side, the rear end of the telescopic positioning pin 7 is inserted into the circular hole on the front side of the tool 8. When the adjusting bracket 5 slides to the front side, the telescopic positioning pin 7 is separated from the circular hole on the front side of the tool 8. When the tool 8 is installed and adjusted, the adjusting bracket 5 can be pushed forward to the front side first. At this time, the telescopic positioning pin 7 also slides forward. Then the left side of the tool 8 can be inserted into the rectangular cavity inside the tool support cylinder 4 from the opening on the right side of the tool support cylinder 4. At this time, the length of the extended part of the tool 8 can be adjusted. When adjusting, one of the circular holes on the front side of the tool 8 is aligned with the circular hole on the front side outer wall of the tool support cylinder 4. After the adjustment is completed, the adjusting bracket 5 can be released. At this time, the magnet on the rear side outer wall of the tool support cylinder 4 cooperates with the magnet inside the vertical plate on the rear side of the adjusting bracket 5 to push the adjusting bracket 5 to move quickly to the last side. Therefore, the rear end of the telescopic positioning pin 7 is inserted into the circular hole on the front side of the tool 8. Therefore, the left and right sliding of the tool 8 in the tool support cylinder 4 can be limited, and the length of the extended part of the tool 8 can be adjusted.

[0033] As shown in the embodiments of the present disclosure, Figure 1 and Figure 2 As shown, a ring-shaped protruding strip is arranged on the outer wall of the first support circular plate 2, and a plurality of notched grooves are equidistantly arranged on the ring-shaped protruding strip. When the adjusting bracket 5 slides forward, the rotation positioning pin 6 is separated from the notched groove on the outer side of the first support circular plate 2. Therefore, the tool support cylinder 4 can be rotationally adjusted between the first support circular plate 2 and the second support circular plate 3, and the angle of the tool 8 can be adjusted. After the adjustment is completed, the adjusting bracket 5 can be released. At this time, the magnet on the rear side outer wall of the tool support cylinder 4 cooperates with the magnet inside the vertical plate on the rear side of the adjusting bracket 5 to push the adjusting bracket 5 to move quickly to the last side. Therefore, the circular rod on one side of the rotation positioning pin 6 is embedded in the notched groove on the outer side of the first support circular plate 2, and the angle of the tool support cylinder 4 and the tool 8 can be fixed.

[0034] As shown in the embodiments of the present disclosure, Figures 1-4As shown, the rotating positioning bolt 6 is a U-shaped rod, and the outer diameter of the round rod portion of the rotating positioning bolt 6 is equal to the width of the notch groove on the outer side of the first support circular plate 2. When the adjusting bracket 5 slides to the last side, the round rod on one side of the rotating positioning bolt 6 will be embedded in the notch groove on the outer side of the first support circular plate 2. When the adjusting bracket 5 slides to the front side, the round rod on one side of the rotating positioning bolt 6 will be separated from the notch groove on the outer side of the first support circular plate 2. After the adjusting bracket 5 slides forward, the rotating positioning bolt 6 will also be separated from the notch groove on the outer side of the first support circular plate 2. Therefore, the tool support cylinder 4 can also be rotated and adjusted between the first support circular plate 2 and the second support circular plate 3, so as to adjust the angle of the tool 8. After the adjustment is completed, the adjusting bracket 5 can be loosened. At this time, the magnet on the rear outer wall of the tool support cylinder 4 will cooperate with the magnet inside the vertical plate at the rear of the adjusting bracket 5 to push the adjusting bracket 5 to move quickly to the last side, so that the round rod on one side of the rotating positioning bolt 6 will be embedded in the notch groove on the outer side of the first support circular plate 2, thereby fixing the angle of the tool support cylinder 4 and the tool 8.

[0035] In example two, on the basis of example one, as shown in Figures 1-6 A magnet is arranged on the rear outer wall of the tool support cylinder 4, and a magnet is also arranged inside the vertical plate at the rear of the adjusting bracket 5. The two magnets repel each other. When the tool 8 is installed and adjusted, the adjusting bracket 5 can be first pushed forward to the front side, and then the tool 8 can be adjusted in extension and rotation. After the adjustment is completed, the adjusting bracket 5 can be loosened. At this time, the magnet on the rear outer wall of the tool support cylinder 4 will cooperate with the magnet inside the vertical plate at the rear of the adjusting bracket 5 to push the adjusting bracket 5 to move quickly to the last side, thereby locking the state of the tool 8.

[0036] The working principle of the embodiment is as follows: when installing, the tool support base 1 can be fixed in the lathe, when installing the tool 8, the adjusting bracket 5 can be pushed forward to the most forward side, at this time, the telescopic positioning pin 7 will also slide forward, then the left side of the tool 8 can be inserted into the rectangular cavity in the tool support cylinder 4 from the opening on the right side of the tool support cylinder 4, and at this time, the length of the protruding part of the tool 8 can be adjusted, when adjusting, one of the circular holes on the front side of the tool 8 can be aligned with the circular hole on the outer wall of the front side of the tool support cylinder 4, and after the adjusting bracket 5 slides forward, the rotating positioning pin 6 will also be disengaged from the notch groove on the outer side of the first supporting circular plate 2, so the tool support cylinder 4 can be adjusted in rotation between the first supporting circular plate 2 and the second supporting circular plate 3, thereby the angle of the tool 8 can be adjusted, after the adjustment is completed, the adjusting bracket 5 can be loosened, at this time, the magnet on the rear side outer wall of the tool support cylinder 4 can cooperate with the magnet in the vertical plate on the rear side of the adjusting bracket 5 to push the adjusting bracket 5 to move rapidly to the last side, so the round rod on one side of the rotating positioning pin 6 can be embedded in the notch groove on the outer side of the first supporting circular plate 2, thereby the angle of the tool support cylinder 4 and the tool 8 can be fixed, and the rear end of the telescopic positioning pin 7 can be inserted into the circular hole on the front side of the tool 8, so the length of the protruding part of the tool 8 can be adjusted.
