[0026] like Figures 1-6 As shown, a grooving device for releasing prestress includes: a cutting machine 1, a slide rail 2 connected to the cutting machine 1, a caster wheel 21 connected to the lower side of the slide rail 2, connecting frames 3 installed at both ends of the slide rail 2, an mounting sleeve 31 connected to the upper side of the connecting frame 3, a rotating rod 4 connected to the mounting sleeve 31, a rotating sleeve 41 fixedly connected to one end of the rotating rod 4, a positioning post 5 rotatably connected to the rotating sleeve 41, the rotating rod 4 being able to rotate around the positioning post 5, a positioning element 6 provided on the upper side of the rotating rod 4, the positioning element 6 being used to fix the position of the rotating rod 4 relative to the positioning post 5, a positioning column 51 extending out of the rotating sleeve 41 fixedly connected to the upper side of the positioning post 5, the positioning element 6 being vertically slidably connected to the positioning column 51, the positioning element 6 being unable to rotate relative to the positioning column 51, and the positioning element 6 having a notch 61 for positioning the rotating rod 4. In this embodiment, the cutting machine 1 can move horizontally along the slide rail 2. The universal wheel 21 can easily change the position of the slide rail 1. The connecting frame 3 is used to connect the mounting sleeve 31 to the slide rail 2. The mounting sleeve 31 and the slide rail 2 move simultaneously. The rotating rod 4 can rotate around the positioning stake 5. After cutting one side is completed, rotating the rotating rod 4 makes the slide rail 2 and the connecting frame 3 move simultaneously, moving the cutting machine 1 to the other side. After the cutting machine 1 rotates to the other side, the positioning piece 6 is moved downward so that the rotating rod 4 is located in the notch. Furthermore, the notch 61 opened by the positioning piece 6 is an arched notch, and there are four notches 61 arranged in a circular array. In this embodiment, the shape of the notch 61 is further defined. The notch 61 of the positioning member 6 is an arched notch. The positioning member 6 falls from above and lands on the rotating rod 4. The arc surface of the notch 61 contacts the rotating rod 4. Each time the rotating rod 4 rotates 90 degrees, it corresponds to an arched notch. The arched notch is set to realize that the rotating rod 4 rotates at an angle of 90 degrees or 180 degrees. The operator can use the arched notch as a reference to rotate the rotating rod 4. During the rotation, the position of the positioning post 5 remains fixed. The universal wheel 21 can reduce the resistance encountered when the rotating rod 4 drives the slide rail 2 to rotate.

[0027] Reference Figure 4 and Figure 5A cylindrical slot is provided at the upper center of the positioning post 5. A rotating post 52 is fixedly connected inside the cylindrical slot of the positioning post 5, and the positioning post 51 is fixedly connected to the upper end of the rotating post 52. In this embodiment, the positioning post 51 and the rotating post 52 are integrally connected, making the structure of the positioning post 51 and the rotating post 52 more stable. The rotating sleeve 41 can move upward along the positioning post 51, or it can be detachably connected, allowing the positioning post 51 and the rotating post 52 to be separated.

[0028] Reference Figure 5 The rotating sleeve 41 is rotatably connected to the rotating column 52. When the positioning member 6 moves upward and disengages from the rotating column 52, the rotating column 52 is no longer restricted by the positioning member 6. In this embodiment, when the rotating column 52 is located within the notch 61 of the positioning member 6, the rotating sleeve 41 cannot rotate under the restriction of the positioning member 6. When the positioning member 6 moves upward and the rotating column 52 is no longer within the notch 61 of the positioning member 6, the rotating column 52 can rotate.

[0029] Reference Figure 5 The lower side of the rotating sleeve 41 extends into the cylindrical groove and is rotatably connected to the rotating column 52. In this embodiment, the positional relationship between the rotating sleeve 41 and the rotating column 52 is further defined, and the rotating sleeve 41 and the rotating column 52 are sleeved and connected; the lower side of the rotating sleeve 41 extending into the cylindrical groove can improve the coaxiality of the rotating sleeve 41 and the rotating column 52.

[0030] Reference Figure 4 A positioning adjustment component 7 is provided between the mounting sleeve 31 and the rotating rod 4, which can fix the mounting sleeve 31 after changing its position on the rotating rod 4. In this embodiment, when the positioning adjustment component 7 is connected to both the mounting sleeve 31 and the rotating rod 4, the position of the mounting sleeve 31 is fixed. After removing the positioning adjustment component 7, the position between the mounting sleeve 31 and the rotating rod 4 can be manually changed.

[0031] Reference Figure 1 The positioning adjustment component 7 is a positioning pin. The rotating rod 4 has multiple first positioning holes 42, and the mounting sleeve 31 has a second positioning hole 311 that is parallel to the axis of the first positioning holes 42 and of equal size. The positioning adjustment component 7 is located in the second positioning hole 311 and the first positioning holes 42. In this embodiment, the positioning adjustment component 7 is further defined such that when the positioning pin is inserted into the first positioning hole 42 and the second positioning hole 311, the position of the mounting sleeve 31 is fixed. The distance between the mounting sleeve 31 and the positioning post 5 can be changed by placing the positioning pin in different first positioning holes 42.

[0032] Reference Figure 3 and Figure 6The positioning post 51 has multiple inwardly recessed vertical grooves arranged in a circular array. The inner side of the positioning member 6 is provided with a vertical protrusion 62 that cooperates with and limits the vertical grooves. In this embodiment, the vertical protrusion 62 and the vertical grooves limit each other, restricting the positioning member 6 to slide vertically relative to the positioning post 51, and preventing it from rotating during the sliding process.

[0033] Reference Figure 1 Push handles 11 are provided on both sides above the cutting machine 1, which can be used to move the cutting machine 1 along the slide rail 2. In this embodiment, the push handles 11 are provided on both sides above the cutting machine 1, which can push the cutting machine 1 in two directions.
