Description

Technical Field

[0001] This utility model relates to the field of polishing device technology, specifically a multi-functional polishing device. Background Technology

[0002] In the restoration of ancient buildings, sanding wooden and stone pillars is a common procedure, and handheld sanders are widely used due to their ease of operation. These sanders are typically powered by a power cord at the end, which extends from the rear or side of the machine. In practice, due to the limited space around the pillars and the need for frequent operator movement, the power cord is easily snagged on surrounding components or subjected to accidental pulling. The power cord exit point of existing sanders is usually a simple fixed sleeve structure. When the power cord is pulled, the tension acts directly on the connection between the power cord and the machine's internal structure. Long-term or sudden pulling can easily lead to loose cable connectors, broken internal wires, or worn insulation, resulting in unstable power supply to the equipment. Summary of the Invention

[0003] The purpose of this utility model is to provide a multifunctional grinding device, which solves the problem of wear at the connection point caused by accidental pulling of the power cord by setting a limiting component with a spiral cable groove.

[0004] This utility model is achieved through the following technical solution: This utility model is a multifunctional polishing device, including a handheld polisher and a column. The end of the handheld polisher is provided with a limiting component. The limiting component has a first fixing block and a second fixing block. The first fixing block and the second fixing block are provided with spiral grooves. The two spiral grooves cooperate to form a spiral cable groove. The second fixing block is provided with a circular groove. A circular magnet is installed in the circular groove. A circular iron block is installed on the outer surface of the first fixing block. The circular magnet and the circular iron block are magnetically connected.

[0005] Furthermore, rubber rings are installed at both ends of the spiral groove.

[0006] Furthermore, the end of the first fixing block has a power cord body, which passes through two rubber rings and is located in a spiral groove.

[0007] Furthermore, both the top of the first and second fixing blocks are equipped with arc-shaped magnets, and the bottom of the handheld grinder is provided with an arc-shaped groove, in which an arc-shaped iron block is installed, and the arc-shaped magnets are magnetically connected to the arc-shaped iron block.

[0008] Furthermore, the handheld grinder has a grinding disc with through holes arranged in a ring shape.

[0009] Furthermore, the grinding disc comes into contact with the outer surface of the cylinder.

[0010] This utility model has the following beneficial effects: This utility model, through the setting of a limiting component with a magnetic fixing block and a spiral cable groove, converts the externally applied linear tension into the torsional deformation of the cable within the spiral cable groove. Through the constraint and guidance of the groove wall, it effectively buffers and absorbs the impact energy, avoids the tension being concentrated on the weak connection point between the power cord and the machine body, and significantly improves the service life and operational reliability of the equipment. This invention utilizes a magnetically attached fixing block and a connection structure with the machine body. By employing the attraction between an arc-shaped magnet and an arc-shaped iron block, the positioning and installation of the limiting component at the end of the grinding machine are achieved. At the same time, it allows the entire limiting component to be easily removed when the power cord needs to be inspected or tidied, facilitating the daily maintenance and pre-operation preparation of the equipment.

[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-4This utility model provides a technical solution: a multifunctional polishing device, including a handheld polisher 1 and a column 10. The column 10 is the part to be repaired. The handheld polisher 1 has a polishing disc 101. The polishing disc 101 has through holes 102 in an annular shape. The polishing disc 101 is in contact with the outer surface of the column 10. The polishing disc 101 polishes the surface of the column 10. During polishing, the dust generated can be effectively discharged through these through holes 102.

[0016] A limiting component is provided at the end of the handheld grinder 1. The end of the handheld grinder 1 is the gripping part, and the limiting component is located at this end to manage and protect the power cord body 9. The limiting component has a first fixing block 2 and a second fixing block 3. The first fixing block 2 and the second fixing block 3 have spiral grooves 301. Rubber rings 6 are installed at both ends of the spiral grooves 301. The end of the first fixing block 2 has the power cord body 9, which passes through the two rubber rings 6 and is located in the spiral groove 301. The rubber rings 6 protect the power cord body 9 from wear when entering and exiting the spiral cable groove. The two spiral grooves 301 cooperate to form a spiral cable groove. The second fixing block 3 has a circular groove 302, and a circular magnet 4 is installed in the circular groove 302. The outer surface of the first fixing block 2... A round iron block 5 is installed on the surface, and a round magnet 4 is magnetically connected to the round iron block 5. When it is necessary to merge the first fixing block 2 and the second fixing block 3, simply align the round iron block 5 with the round magnet 4. The two will automatically attract and fit tightly under the action of magnetic force, thereby sealing the spiral cable groove. When the power cord body 9 is accidentally hooked by an obstacle or pulled by an external force during operation, the pulling force first acts on the spiral section of the cable. The groove wall of the spiral cable groove will constrain the cable, forcing this spiral section of the cable to produce a slight torsional deformation or attempt to rotate in the groove, thereby effectively converting a part of the direct and violent pulling force into a mild torsional force, absorbing the impact energy, and avoiding the pulling force being directly and concentratedly transmitted to the connection point between the power cord body 9 and the internal circuit of the handheld grinder 1.

[0017] The top of the first fixing block 2 and the second fixing block 3 are both equipped with arc-shaped magnets 7. The bottom of the handheld grinder 1 is provided with an arc-shaped groove 103. An arc-shaped iron block 8 is installed in the arc-shaped groove 103. The arc-shaped magnet 7 and the arc-shaped iron block 8 are magnetically connected. When installing the limiting component, after the power cord body 9 has been placed in the spiral cable groove and the first fixing block 2 and the second fixing block 3 have been merged, the entire limiting component is moved toward the end of the handheld grinder 1 until the arc-shaped magnet 7 at the top is embedded in the arc-shaped groove 103 and magnetically connected with the arc-shaped iron block 8 therein.

[0018] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
