[0002] An angle grinder is a multi-functional power tool mainly used for various processing tasks such as cutting, grinding, polishing, and drilling. When an angle grinder cuts materials, it is necessary to control a certain cutting depth to prevent the grinding wheel or other cutting blades from cutting too deeply or too shallowly, which would lead to low cutting efficiency or safety issues. In existing technologies, controlling the cutting depth mostly relies on the user's visual estimation and manual pressure, which is not only prone to errors but also carries significant operational risks. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an angle grinder with adjustable cutting depth, which has the advantage of being able to precisely adjust the cutting depth of the angle grinder, thus solving the problem that existing technologies mostly rely on visual estimation by users, resulting in significant errors and operational risks.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] An adjustable cutting depth angle grinder includes a main body mechanism as the main body of the device. The main body mechanism includes a worktable. A cutting mechanism for easy adjustment of the cutting depth is provided at the bottom of the main body mechanism. An adjustment mechanism for easy adjustment of the cutting angle is provided on the main body mechanism. The cutting mechanism includes a fixed frame fixedly connected to the bottom of the worktable. A round rod is rotatably connected to the fixed frame. Arc-shaped plates are fixedly connected to both ends of the round rod. A connecting rod is fixedly connected between the two arc-shaped plates. A round plate is fixedly connected to both ends of the connecting rod. Two arc-shaped guide rails are fixedly connected to the bottom of the worktable. An angle grinder body is installed between the two arc-shaped plates. Limiting holes are provided on both arc-shaped guide rails. A fixed rod is fixedly connected to the opposite side of each of the two round plates. An adjustment component for easy adjustment of the position of the angle grinder body is provided at the bottom of the worktable.

[0006] Preferably, the adjustment assembly includes a fixed plate and a movable plate. A guide rod is fixedly connected to the fixed plate, and a screw is rotatably connected to the fixed plate. Limit rods are fixedly connected to both sides of the movable plate. The two fixed rods are respectively located on the two limit rods. Rotary rods are rotatably connected between the two arc-shaped plates and the angle grinder body. An adjustment motor for driving the rotary rod is installed on one side of one of the arc-shaped plates.

[0007] Preferably, the length of the connecting rod is the same as the maximum distance between the two arc-shaped guide rails, the connecting rod is located in the two limiting holes, the moving plate and the screw are threadedly connected, the moving plate and the guide rod are slidably connected, and a servo motor for driving the screw is installed at the bottom of the fixed plate.

[0008] Preferably, the adjustment mechanism includes a slot and a square slot formed on the workbench.

[0011] By employing the above technical solution, this utility model provides an angle grinder with adjustable cutting depth, which has at least the following beneficial effects:

[0012] 1. This utility model, by setting a cutting mechanism, enables the device to easily adjust the cutting depth of materials. The servo motor drives the screw to rotate, causing the moving plate to slide on the guide rod. The moving plate drives the two limiting rods to move up and down, which in turn drives the two fixed rods to move. This causes the connecting rod to slide within the limiting hole, causing the round rod to rotate. This causes the grinding wheel of the angle grinder to move upward, making it easy to adjust the relative distance between the grinding wheel and the top of the worktable, thereby determining the cutting depth and improving the cutting effect of the device.

[0013] 2. This utility model enables the device to easily adjust the cutting angle of materials by setting an adjustment mechanism. The micro motor drives the drive gear to rotate. Since the drive gear meshes with the driven gear, the angle of the baffle driven by the driven gear can be easily adjusted and fixed. By placing one end of the material on the baffle, the grinding wheel can cut it at the corresponding angle, ensuring the cutting effect of the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the prior art, the cutting depth of materials is mostly controlled by the user's visual estimation and manual pressure control, which not only has errors but also has a large operational risk. The following describes some embodiments of the present invention with reference to the accompanying drawings, providing an angle grinder with adjustable cutting depth.

[0023] Example 1:

[0024] To ensure the cutting effect of the device, combined with Figure 1 , Figure 2 and Figure 3 As shown, an angle grinder with adjustable cutting depth is proposed. The main body 1 is set as the main body of the device. The bottom of the main body 1 is provided with a cutting mechanism 2, which is used to easily adjust the cutting depth of the material. The main body 1 is provided with an adjustment mechanism 3, which is used to easily adjust the cutting angle of the material.

[0025] To precisely adjust the cutting depth of the material, a cutting mechanism 2 is proposed. A fixed frame 201 is fixedly connected to the bottom of the worktable 101. A round rod 202 is rotatably connected to the fixed frame 201. Arc-shaped plates 203 are fixedly connected to both ends of the round rod 202. A connecting rod 205 is fixedly connected between the two arc-shaped plates 203. Round plates are fixedly connected to both ends of the connecting rod 205. Two arc-shaped guide rails 206 are fixedly connected to the bottom of the worktable 101. The length of the connecting rod 205 is the same as the maximum distance between the two arc-shaped guide rails 206. An angle grinder body is installed between the two arc-shaped plates 203. 204. Limiting holes 207 are provided on both arc-shaped guide rails 206. Connecting rods 205 are located in the two limiting holes 207. Fixing rods 208 are fixedly connected to the opposite sides of the two circular plates. An adjustment component 209 is provided at the bottom of the worktable 101. The adjustment component 209 is used to easily adjust the position of the angle grinder body 204. A fixed plate 2091 and a moving plate 2094 are provided. A guide rod 2092 is fixedly connected to the fixed plate 2091. The moving plate 2094 and the guide rod 2092 are slidably connected. A screw 2093 is rotatably connected to the fixed plate 2091. A threaded connection is made between the screw 2094 and the guide rod 2093. A servo motor for driving the screw 2093 is installed at the bottom of the fixed plate 2091. Limit rods 2095 are fixedly connected to both sides of the moving plate 2094. Two fixed rods 208 are respectively located on the two limit rods 2095. Rotating rods are rotatably connected between the two arc-shaped plates 203 and the angle grinder body 204. An adjusting motor 2096 for driving the rotating rod is installed on one side of one arc-shaped plate 203. The servo motor drives the screw 2093 to rotate, causing the moving plate 2094 to slide on the guide rod 2092, thus moving the moving plate 2094. The two limiting rods 2095 move up and down, enabling them to drive the two fixed rods 208 to move. This causes the connecting rod 205 to slide within the limiting hole 207, resulting in the rotation of the round rod 202. Consequently, the grinding wheel of the angle grinder body 204 moves upward, allowing for easy adjustment of the relative distance between the grinding wheel and the top of the worktable 101. This determines the cutting depth and improves the cutting effect of the device. Simultaneously, by adjusting the motor 2096, the relative distance between the angle grinder body 204 and the arc plate 203 can be easily adjusted, further enabling adjustment of the cutting depth and ensuring the cutting effect of the device.

[0026] Example 2:

[0027] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that in the prior art, when controlling the cutting depth, the user mostly relies on visual estimation and manually presses down to control the cutting depth, which not only has errors but also has a large operational risk. However, when cutting materials, if the materials can only be placed on a plane, the cutting angle is relatively simple, which is not conducive to meeting different needs.

[0028] To meet the needs of different cutting angles, combined with Figure 1 and Figure 4 As shown, an adjustment mechanism 3 is proposed. A slot 301 and a square groove are formed on the worktable 101. A support rod is rotatably connected within the slot 301, and a baffle 302 is fixedly connected to the support rod. A driven gear 303 is rotatably connected within the square groove, and a micro motor is installed within the square groove. A driving gear 304 is fixedly connected to the drive shaft of the micro motor. One end of the support rod is fixedly connected to the driven gear 303. The driven gear 303 and the driving gear 304 mesh with each other. The micro motor drives the driving gear 304 to rotate. Because the driving gear 304 meshes with the driven gear 303, the angle at which the driven gear 303 drives the baffle 302 can be easily adjusted and fixed. By placing one end of the material above the baffle 302, the grinding wheel can cut it at the corresponding angle, ensuring the cutting effect of the device and thus meeting the needs of different cutting angles.

[0029] To facilitate the easy connection and fixation of various mechanisms, a main mechanism 1 is proposed. A workbench 101 is provided, with multiple support columns 102 fixedly connected to the bottom of the workbench 101. A through hole 103 is provided on the workbench 101, and a protective cover 104 is installed on the workbench 101. The protective cover 104 is made of transparent material. The multiple support columns 102 support the entire device. The through hole 103 facilitates the observation of the cutting depth of the grinding wheel. The protective cover 104 prevents debris from flying and protects the personal safety of the workers.
