[0002] The origin of bicycle frames is closely related to the development of bicycles. Since the 20th century, with the continuous advancement of materials science and manufacturing processes, the materials and manufacturing technologies of bicycle frames have also been constantly developing. From the initial iron and steel materials, they have gradually evolved to high-performance materials such as aluminum alloys, titanium alloys, and carbon fiber. These materials not only make the frames lighter and stronger, but also significantly improve shock absorption and rigidity, meeting different riding needs and competitive requirements. At the same time, manufacturing processes have also evolved from traditional welding and forging to advanced CNC machining and mold forming, greatly improving the precision and quality of the frames.
[0003] In the existing technology, welding is a common way to connect various parts in the bicycle frame manufacturing process, leaving weld seams. This tool can be used to finely grind the weld seams to make the surface smooth and flat, which not only improves the aesthetics of the frame, but also eliminates welding stress. However, the frame is not fixed during the grinding process, which can easily cause shaking and displacement, affecting the grinding quality. In addition, a lot of dust is generated during the grinding process, which affects the surrounding environment.
[0004] Therefore, a convenient handheld grinding tool for bicycle frames is proposed. Utility Model Content

[0029] Based on Embodiment 1, a preferred embodiment of the conveniently clamped handheld grinding tool for bicycle frames provided by this utility model is as follows: Figure 1-4As shown: The sanding and dust collection assembly 5 specifically includes: a dust collection cylinder 511, fixedly installed between the inner walls of the collar 3; a filter sleeve 512, fixedly installed on the top of the dust collection cylinder 511; air vents 513, circumferentially equidistantly opened on the outer wall of the filter sleeve 512; a top cylinder 514, fixedly installed on the top of the filter sleeve 512; a connecting block 515, circumferentially equidistantly fixedly installed on the bottom of the dust collection cylinder 511; a protective ring 516, fixedly installed on the outer wall of the connecting block 515; a locking block 517, fixedly installed between the inner walls of the filter sleeve 512; a motor 518, fixedly installed on the bottom of the inner wall of the top cylinder 514; a sealing frame 519, disposed between the inner walls of the filter sleeve 512; a filter screen 5111, fixedly installed between the inner walls of the sealing frame 519; a rotating rod 5115, disposed inside the dust collection cylinder 511; and a dust collection pipe 5117, circumferentially equidistantly and evenly connected to the outer wall of the dust collection cylinder 511.
[0030] The output end of the motor 518 is fixedly equipped with a rotating shaft, and the other end of the rotating shaft moves through the bottom of the inner wall of the top cylinder 514, the top of the locking block 517 and extends to the bottom of the locking block 517.
[0031] The outer wall of the filter sleeve 512 has a hole, and an arc plate 5112 is engaged between the inner walls of the hole. One side of the arc plate 5112 is fixedly connected to the outer wall of the sealing frame 519. The other side of the arc plate 5112 and the outer wall of the filter sleeve 512 are respectively fixedly installed with groove blocks 5113. Magnets 5114 are fixedly installed between the inner walls of the groove blocks 5113, and the magnets 5114 attract each other.
[0032] The top of the rotating rod 5115 is fixedly connected to the other end of the rotating shaft. The outer wall of the rotating rod 5115 is fixedly fitted with a fan impeller 5116. The bottom of the rotating rod 5115 moves through the bottom of the inner wall of the vacuum cleaner 511 and extends to the bottom of the vacuum cleaner 511. The bottom of the vacuum cleaner pipe 5117 has suction ports evenly spaced at equal intervals. The bottom of the rotating rod 5115 is fixedly installed with a grinding wheel 5118.
[0033] In this example, the grinding and dust collection component 5 can be set up to perform grinding and dust collection. The motor 518 is started to drive the rotating shaft and the rotating rod 5115 to rotate, which drives the grinding wheel 5118 to grind the frame. The protective ring 516 can protect the grinding wheel 5118. When the rotating rod 5115 rotates, it drives the fan impeller 5116 to rotate and generate airflow.

After the bottom bracket of the bicycle frame is fixed, the frame can be further pressed and limited with one hand, while the other hand can be used for grinding. The grinding device can be easily carried through the handle 1. Pressing the button 2 starts the motor 518. The rotating shaft and rotating rod 5115 rotate, driving the grinding wheel 5118 to grind the frame. The protective ring 516 can protect the grinding wheel 5118. When the rotating rod 5115 rotates, it drives the fan impeller 5116 to rotate and generate airflow. Dust enters the suction pipe 5117 through the suction port, then enters the suction cylinder 511 and the filter sleeve 512. The dust is filtered by the filter screen 5111. The filtered air is discharged through the vent hole 513. Pull out the bottom groove block 5113 and magnet 5114. Separate the two magnets 5114. The sealing frame 519 and filter screen 5111 can be removed from the filter sleeve 512. The filter screen 5111 can be cleaned. At the same time, the dust inside can be poured out through the vent hole 513, thus achieving the functions of clamping, grinding and dust collection.
