[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] Example 1:

[0031] A type of beveling tool, such as Figures 1-4As shown, the device includes a handle 1 and a support mechanism 2 slidably connected thereto. An adjustable chamfering mechanism 3 is provided at the end of the handle 1. The chamfering mechanism 3 includes an L-shaped support rod 301. Two cutting blades 302 are rotatably connected to the bottom of the L-shaped support rod 301. A lever 303 is provided between the two cutting blades 302. The lever 303 controls the rotation of the cutting blades 302 through a connecting rod 304. The adjustable chamfering mechanism 3 at the end of the handle 1 allows the user to adjust the angle of the cutting blades 302 according to actual needs, thereby achieving precise chamfering of different parts of the pipe or workpiece, improving the accuracy and efficiency of the chamfering operation.

[0032] See Figure 3 One of the connecting rods 304 has a threaded connection to a locking bolt 305 on one side. The locking bolt 305 is used to fix the cutting blade 302. The fixing function of the locking bolt 305 also improves the accuracy and consistency of the chamfering operation and ensures the reliability of the chamfering quality.

[0033] See Figure 3 The support mechanism 2 includes a sliding frame 201, with support plates 202 fixedly connected to both sides of one end of the sliding frame 201. The presence of the support plates 202 increases the contact area between the chamfering device and the pipe or workpiece, thereby improving stability.

[0034] See Figure 3 The two support plates 202 are set at a 90-degree angle. A wear-resistant plate 203 is fixedly connected to the front side of the support plate 202. The addition of the wear-resistant plate 203 reduces friction and wear between the support plate and the pipe, extends the service life of the chamfering tool, and reduces maintenance costs.

[0035] See Figure 3 The front end of the L-shaped support rod 301 is provided with a sliding groove 306, and a pressure rod 307 is slidably connected inside the sliding groove 306. The presence of the pressure rod 307 can also press the pipe tightly to prevent shaking or displacement during the chamfering process, thereby improving the accuracy and safety of the chamfering operation.

[0036] See Figure 3 A pressure spring 308 is provided between the pressure rod 307 and the sliding groove 306. The top of the pressure rod 307 is threaded with a fixing bolt 309 for fixing. The fixing bolt 309 threaded on the top of the pressure rod 307 allows the user to tighten it to achieve fixation, further improving the accuracy of the chamfering operation.

[0037] See Figure 3 The sliding frame 201 is threaded with a fixed handle 204. The fixed handle 204 passes through the keyway 101 on the handle 1 to lock the support mechanism 2. The fixed handle 204 passing through the keyway 101 on the handle 1 makes the operation of the fixed handle 204 more convenient, and also increases the overall structural strength of the chamfering tool.

[0038] The implementation principle of this utility model is as follows: First, when it is necessary to cut the chamfer of the outer ring, the cutting blade 302 is slid outward until it is exposed on the left side;

[0039] Then, by operating the lever 303 on the L-shaped support rod 301, the angle of the two cutting blades 302 can be adjusted through the connecting rod 304. Then, tighten the locking bolt 305 on one side of one of the connecting rods 304 so that the locking bolt 305 is pressed against the L-shaped support rod 301, thereby ensuring that the cutting blade 302 will not change its angle due to external force during operation.

[0040] Then, insert the pipe between the pressure rod 307 and the left cutting blade 302. At this time, the pressure rod 307 presses the inner wall of the pipe under the pressure of the pressure spring 308. Tighten the fixing bolt 309 so that the outer wall of the pipe and the left cutting blade 302 are pressed together. Slide the sliding bracket 201 so that the pipe can contact the support plate 202. Tighten the fixing handle 204 on the sliding bracket 201 to lock the support mechanism 2.

[0041] Hold the handle 1 and manually rotate the chamfering tool so that the cutting blade 302 can perform the chamfering operation;

[0042] When it is necessary to chamfer the inner corner, pull out the right-side cutting blade 302, then insert the pipe into the right-side cutting blade 302 so that the right-side cutting blade 302 presses against the inner wall of the pipe, slide the sliding bracket 201 so that the pipe can contact the support plate 202, and tighten the fixed handle 204 on the sliding bracket 201 to lock the support mechanism 2.

[0043] Manually rotate the chamfering tool so that the cutting blade 302 can perform the chamfering operation.

[0044] Example 2:

[0045] See Figure 4 One of the support plates 202 has a through hole 4, and a fixing ring 5 is fixedly connected to the rear side of the support plate 202. The through hole 4 passes through the support plate 202 at an angle, so that space can be left for the grinding head to grind. The addition of the fixing ring 5 provides users with a convenient way to fix other tools or accessories, further expanding the application range and usage flexibility of the chamfering tool.

[0046] The implementation principle of this utility model is as follows: First, when it is necessary to use an electric grinder for grinding, remove the cutting blade 302 on the right side, then insert the grinding end of the electric grinder into the through hole 4, and tighten the fixing bolt on the fixing ring 5 to fix it.

[0047] Then insert the pipe into one side of the pressure rod 307. At this time, the pressure rod 307 presses the inner wall of the pipe under the pressure of the pressure spring 308. Tighten the fixing bolt 309, slide the sliding bracket 201 so that the pipe can contact the support plate 202, and tighten the fixing handle 204 on the sliding bracket 201 to lock the support mechanism 2.

[0048] Turn on the electric grinder and manually rotate the chamfering tool so that the electric grinder can perform the chamfering operation.
