[0024] Example 1

[0025] A guide sleeve type tool rest, such as Figure 1-Figure 4 As shown, it includes a first rotating frame 1 and a moving bolt 2 fixedly arranged on one side of the first rotating frame 1, characterized in that the moving bolt 2 is fixedly connected with a horizontal fastening ring 4 through a supporting column 3, there are at least two supporting columns 3, and the two supporting columns 3 are both threadedly screwed with the moving bolt 2, and a height moving frame 5 is arranged above the moving bolt 2, and the height moving frame 5 is fixedly connected with an upper fastening ring 7 through an arc support rod 6, and the arc support rod 6 is fixedly connected to the height moving frame 5. When the staff rotates the first rotating frame 1 to rotate the moving bolt 2, the two supporting columns 3 are located in relative positions and the thread directions inside them are different, so that the two horizontal fastening rings 4 are supported by the two supporting columns 3. The upper fastening ring 7 is moved under the support of the arc support rod 6 by adjusting the height position of the height moving frame 5, and the upper fastening ring 7 and the two horizontal fastening rings 4 are moved simultaneously, so as to adjust the size of the guide sleeve in the middle of the device, and can timely adjust the device specifications according to the size of the processing material, and can improve the scope of use of the device.

[0026] like Figure 1-Figure 4 As shown, a rotating support block 8 is inserted into the side of the movable bolt 2 away from the first rotating frame 1. There are at least two rotating support blocks 8, and the two rotating support blocks 8 are respectively located on both sides of the two support columns 3. The rotating support block 8 is used to support the fixing and stability of the movable bolt 2 during rotation, and is characterized in that a fixed limit block 9 is fixedly arranged between the two rotating support blocks 8, and the fixed limit block 9 is located between the two support columns 3. The movable bolt 2 is slidably connected with the fixed limit block 9. When the first rotating frame 1 drives the movable bolt 2 to rotate, its position is fixed during rotation under the support of the rotating support blocks 8 and the fixed limit blocks 9 on both sides, and at the same time, it can drive the two support columns 3 to move. The fixed limit blocks 9 limit the positions of the two support columns 3 to ensure that the support columns 3 are within a controllable range when moving.

[0027] like Figure 1-Figure 4 As shown, the rotating support block 8 and the fixed limit block 9 are fixedly connected to the fixed support plate 10 at the same time, and the fixed support plate 10 is slidably connected to the sliding support rod 11 through the sliding support chamber 12. The sliding support chamber 12 is located at the upper end of the fixed support plate 10, and the sliding support rod 11 is plugged into the support column 3. When the support column 3 moves, it will drive the sliding support rod 11 to slide under the support of the sliding support chamber 12. The sliding support chamber 12 and the fixed support plate 10 support the two sliding support rods 11 when sliding, and the rotating support block 8 and the fixed limit block 9 when fixedly supporting them, thereby ensuring the stability of the two support columns 3 when moving and the accuracy of the direction.

[0028] Example 2

[0029] A guide sleeve type tool rest, such as Figure 1-Figure 4 As shown, the fixed support plate 10 is fixedly connected to fixed support blocks 13 on both sides of the relative sides, and a height movable frame 5 is arranged on the upper ends of the two fixed support blocks 13 at the same time. At least two height adjustment bolts 14 are screwed and connected to the upper ends of the height movable frame 5. The height adjustment bolt 14 passes through one end of the height movable frame 5 and is slidably connected to the fixed support block 13. By rotating the height adjustment bolt 14, the height adjustment bolt 14 adjusts the height position of the height movable frame 5 under the support of the fixed support block 13. By adjusting the two height adjustment bolts 14 on both sides at the same time, under the support of the two fixed support blocks 13, the stability of the height movable frame 5 when driving the upper device to move is guaranteed.

[0030] like Figure 1-Figure 4As shown, one end of the fixed support plate 10 away from the rotating support block 8 is fixedly connected with at least two fixed blocks 15, and the fixed block 15 is used to fix the support device for use. The fixed block 15 is fixedly connected with a second rotating frame 17 by a rotating bolt 16, and the rotating bolt 16 is threadedly screwed with the fixed block 15. The rotating bolt 16 is rotated at the same time by rotating the second rotating frame 17. Under the fixed support action of the fixed block 15 and the fixed support plate 10, the second rotating frames 17 on both sides are rotated at the same time, so that the device can be fixed and stably, thereby ensuring the reliability of the device when in use.

[0031] Working principle: the staff rotates the first rotating frame 1 to make the movable bolt 2 rotate. The two support columns 3 are located in relative positions and the directions of the threads inside them are different, so that the two horizontal fastening rings 4 move to opposite positions under the support of the two support columns 3. At the same time, by adjusting the height position of the height movable frame 5, the upper fastening ring 7 moves under the support of the arc support rod 6, and the upper fastening ring 7 and the two horizontal fastening rings 4 are moved simultaneously, so as to adjust the size of the guide sleeve in the middle of the device. The device specifications can be adjusted in time according to the size of the processed material, and the range of use of the device can be improved. At the same time, when the first rotating frame 1 drives the movable bolt 2 to rotate, the position of the movable bolt 2 is fixed under the support of the rotating support blocks 8 and the fixed limit blocks 9 on both sides. At the same time, it can drive the two support columns 3 to move. The fixed limit blocks 9 limit the positions of the two support columns 3 to ensure that the support columns 3 are within a controllable range when moving.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
