This process requires the use of tools to tighten the bolts one by one, which makes it inconvenient to install. In turn, the operator needs to spend a lot of time replacing the annular cutting tools, resulting in low cutting efficiency for wear-resistant steel plates in actual use. Therefore, it is necessary to design and modify the annular cutting tools for processing wear-resistant steel plates to effectively prevent the inconvenience of installation. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, a ring-shaped cutting tool for machining wear-resistant steel plates comprises a driving shaft 1, a groove 2 is arranged on the front side of the driving shaft 1, a mounting block 3 is movably connected inside the groove 2, a round rod 4 is fixedly connected to the front side of the mounting block 3, a ring-shaped tool 5 is fixedly connected to the surface of the round rod 4, a slide groove 6 is arranged on both sides of the front side of the driving shaft 1, and a slider 7 is movably connected inside the slide groove 6, a compression spring 11 is fixedly connected to the surface of the slider 7, the compression spring 11 is fixedly connected to the slide groove 6, a limit block 8 is fixedly connected to the surface of the slider 7, the limit block 8 is movably connected to the mounting block 3, a fixing rod 9 is fixedly connected to the surface of the slider 7, a driving block 10 is fixedly connected to the surface of the fixing rod 9, a circular ring 12 is threadedly connected to the surface of the driving shaft 1, and the circular ring 12 is movably connected to the driving block 10.

[0022] refer to Figures 2 to 4 A gear ring 13 is fixedly connected to the front of the circular ring 12, and movable grooves 14 are provided at the top and bottom of the front of the driving shaft 1. A movable column 15 is movably connected inside the movable groove 14, and teeth 16 are fixedly connected to the surface of the movable column 15. A tension spring 17 is fixedly connected to the surface of the movable column 15, and the tension spring 17 is fixedly connected to the movable groove 14.

[0023] As a technical optimization scheme of the utility model, through the arrangement of the gear ring 13, the movable groove 14, the movable column 15, the teeth 16 and the tension spring 17, when the driving shaft 1 rotates, the movable column 15 and the teeth 16 will be driven to rotate around the axis of the driving shaft 1. Under the action of centrifugal force, the movable column 15 and the teeth 16 move to the side away from the round rod 4, so that the teeth 16 engage with the gear ring 13, and then lock the gear ring 13, and then lock the circular ring 12 to prevent the circular ring 12 from rotating.

[0024] refer to Figure 1 , Figure 2 and Figure 4 The inner thread of the ring 12 is connected with a bolt 18, the bolt 18 is movably connected with the driving shaft 1, and the surface of the thread is sprayed with anti-rust paint.

[0025] As a technical optimization solution of the utility model, through the setting of the bolt 18, the operator can tighten the bolt 18 so that the bolt 18 is tightly attached to the driving shaft 1, thereby locking the ring 12 to prevent the ring 12 from rotating.

[0026] refer to Figure 2 and Figure 5 , the driving block 10 is spherical.

[0027] As a technical optimization solution of the utility model, the driving block 10 is spherical so that any position on the surface of the driving block 10 is arc-shaped, thereby facilitating the ring 12 to push the driving block 10 to move toward the side close to the round rod 4 .

[0028] refer to Figure 1 , Figure 2 and Figure 4 The inner wall of the ring 12 is set at a guide angle.

[0029] As a technical optimization solution of the utility model, the inner wall of the circular ring 12 is set at a guide bevel, so that when the circular ring 12 contacts the driving block 10, the driving block 10 can be better pushed to move to the side close to the round rod 4.

[0030] refer to Figure 1 , Figure 2 and Figure 4 The surface of the ring 12 is provided with anti-slip grooves, and the number of the anti-slip grooves is several, and the anti-slip grooves are evenly distributed on the surface of the ring 12.

[0031] As a technical optimization solution of the present invention, the anti-slip pattern is provided to increase the friction between the operator's hand and the ring 12 , thereby making it easier for the operator to rotate the ring 12 .

[0032] The working principle and use process of the utility model are as follows: during use, when the operator needs to install the annular tool 5, the operator inserts the mounting block 3 into the groove 2, and then the operator rotates the ring 12 to make the ring 12 move toward the front. In the process of moving toward the front, the ring 12 will push the driving block 10 to move toward the side close to the round rod 4, and then drive the slider 7 and the limit block 8 to move toward the side close to the round rod 4 until the limit block 8 is movably connected with the mounting block 3. At this time, under the action of the limit block 8, the mounting block 3 is prevented from moving toward the front, and then the operator tightens the bolt 18 to lock the ring 12.
