[0018] (2) The telescopic cutter head is controlled and extended by controlling the adjustment of the tool sleeve. When the telescopic cutter head is retracted, the two linkage rods are in conflict with the bottom surface of the water storage sleeve, thereby driving the linkage plate to move in the clockwise direction. Driven by the linkage plate, the rotating column rotates, thereby driving the fan-shaped plate to rotate. After the fan-shaped plate rotates, it drives the interference limit plate to rotate. After the interference limit plate moves, it drives the limit block to slide in the limit groove and drives the guide rod to slide in the limit groove. Under the push of the guide rod, the cutter head can be driven to move. At the same time, after the linkage plate moves, the spring is continuously compressed, so that the push rod and the cutter head are in conflict, which is helpful for adjusting the angle of the fine boring tool during operation, and can cope with boring and milling at different angles, thereby improving the use effect.

A through hole 32 is opened on the outer wall of the cutter head 11, and a plurality of anti-skid teeth 33 are arranged on the upper and lower sides of the inner side of the through hole 32. The anti-skid rod 34 is interlaced with the through hole 32 and used in conjunction with the anti-skid teeth 33. A limiting box 31 is arranged in an annular shape inside the cutter head 11, and a linkage plate 30 is slidingly arranged on the inner side of the limiting box 31, and the linkage plate 30 is in conflict with the first chuck 25.

[0035] Embodiment 2, as Figures 1 to 3As shown, on the basis of Example 1, the present invention provides a technical solution: the adjustment component 553 includes a rotating column 15 rotatably installed on the outer edge of the telescopic cutter head 6, the outer surface of the rotating column 15 is fixedly connected with a linkage plate 18, the upper surface of the linkage plate 18 is fixedly connected with two linkage rods 13, the linkage rods 13 correspond to the tool sleeve adjustment 2, the middle part of the linkage plate 18 is movably provided with a push rod 16, the push rod 16 is located on the lower outer surface of the linkage plate 18 and is provided with a spring 8, the outer surface of the rotating column 15 is fixedly connected with a fan-shaped plate 21, the bottom end of the fan-shaped plate 21 is fixedly connected with a resistance limiting plate 9, the resistance limiting plate 9 is provided with a limiting groove 20, the inner side of the limiting groove 20 is slidably provided with a limiting block 19, the bottom end of the limiting block 19 is fixedly connected with a guide rod 37, the upper surface of the cutter head 11 is provided with a limiting groove 17, and the guide rod 37 is slidably in contact with the limiting groove 17.

[0036] In this embodiment, the control tool sleeve adjustment 2 is used to control the telescopic cutter head 6 to perform a telescopic operation. When the telescopic cutter head 6 contracts, the two linkage rods 13 are in conflict with the bottom surface of the water storage sleeve 4, thereby driving the linkage plate 18 to move in the clockwise direction. Driven by the linkage plate 18, the rotating column 15 rotates, thereby driving the fan-shaped plate 21 to rotate.

[0037] The following is a detailed description of the working principle of this precision boring tool with adjustable angle and diameter.

[0038] like Figure 1-8As shown, when the user uses this tool, the user places the fine boring tool in the tool groove 14 on the tool head 11 and pushes it into the positioning groove 36. When sliding in, the linkage plate 30 is pushed to slide in the limiting box 31, so that the other side of the linkage plate 30 extends out and pushes the first chuck 25 to move. After the first chuck 25 moves, it drives the first connecting rod 24 and the second connecting rod 27 to rotate an angle respectively, thereby driving the first limit block 29 and the second limit block 35 to rotate to the upper and lower end surfaces of the boring tool 10 to engage with them respectively. At the same time, under the movement of the first chuck 25, the bayonet 26 can be pushed to be inserted into the hole on the boring tool 10. When the first connecting rod 24 rotates, the first linkage disk 22 rotates, thereby driving the rotating head 23 to rotate, driving the anti-skid rod 34 to move in the through port 32, and constantly rubbing against the anti-skid teeth 33. At this time, the installation of the fine boring blade is completed. When it needs to be replaced, it is only necessary to manually push the anti-skid rod 34 to reset it. When milling, start 5 to send out the water in 4 and spray it on the milled workpiece to prevent milling debris from splashing, which helps to quickly install and replace the fine boring tool and improve the overall movement efficiency. The telescopic tool head 6 is controlled and telescopic by controlling the tool sleeve adjustment 2. When the telescopic tool head 6 shrinks, the two linkage rods 13 are in conflict with the bottom surface of the water storage sleeve 4, thereby driving the linkage piece 18 to move in the clockwise direction. Driven by the linkage piece 18, the rotating column 15 rotates, thereby driving the fan plate 21 to rotate. After the fan plate 21 rotates, it drives the conflict limiting piece 9 to rotate. After the conflict limiting piece 9 moves, it drives the limit block 19 to slide in the limit groove 20, and drives the guide rod 37 to slide in the limit groove 17. Under the push of the guide rod 37, the tool head 11 can be driven to move. At the same time, after the linkage piece 18 moves, the spring 8 is continuously compressed, so that the push rod 16 conflicts with the tool head 11, thereby completing the operation of the fine boring tool.

[0039] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
