[0023] Please refer to Figure 1 Figure 6 The utility model provides technical scheme: based on thermoplastic elastomer deburring tool, including handle 1 and connecting part 3, connecting part 3 is composed of scraping head 31, connecting block 32 and insertion hole 33, scraping head 31 is fixedly installed in the top of connecting block 32, and insertion hole 33 is set up in the outer wall of connecting block 32;The top of handle 1 is fixedly connected with mounting seat 2, and the outer wall of handle 1 is provided with anti-skid sleeve 4, the top of mounting seat 2 is provided with mounting groove 21, the inner wall of mounting seat 2 and the middle part of mounting groove 21 are provided with positioning groove 23, the outer diameter of connecting block 32 is adapted to the inner diameter of mounting groove 21, and the inner wall of positioning groove 23 is provided with limiting assembly 5 for fixing connecting block 32.

[0024] Through handle 1, mounting seat 2 can be installed, because the top of mounting seat 2 is provided with mounting groove 21, so that connecting block 32 is inserted into mounting groove 21, and limiting assembly 5 is inserted into insertion hole 33, so that connecting block 32 can be limited, and then different sizes and shapes of scraping head 31 can be freely fixed;

[0025] Conversely, limiting assembly 5 is stretched outward, so that it is separated from insertion hole 33, and connecting block 32 is released from the limitation, and connecting block 32 and scraping head 31 are taken out from mounting groove 21, and then the problems that the integrated design of the scraper cannot meet the use requirements under different conditions, and when different sizes or shapes of scraping heads are needed, many scrapers must be purchased, and the use and storage are inconvenient are solved;

[0026] And because the outer wall of handle 1 is provided with anti-skid sleeve 4, when the device is used, the hand feeling is comfortable, the hand fatigue is reduced, the slipping phenomenon is avoided, and the safety is improved.

[0027] Please refer to Figure 2 Figure 3 ​​The top of the mounting seat 2 and the outer wall annular array of the mounting groove 21 have three clamping grooves 22, the outer wall annular array of the connecting block 32 has three clamping blocks 34, and the limiting assembly 5 is located on the outer wall of the mounting groove 21, and the insertion hole 33 is located on the outer wall of the connecting block 32.

[0028] Through the connecting block 32, the three clamping blocks 34 can be installed. Since the top of the mounting seat 2 and the outer wall annular array of the mounting groove 21 have three clamping grooves 22, when the scraping head 31 is installed, the three clamping blocks 34 are inserted into the three clamping grooves 22, the connecting block 32 is located in the mounting groove 21, and the insertion hole 33 is flush with the limiting assembly 5, thereby facilitating the limiting of the connecting block 32 by the limiting assembly 5.

[0029] Referring to Figure 4 , Figure 5 , the limiting assembly 5 includes an insertion rod 51, a limiting ring 52, and a spring 53. The limiting ring 52 is fixedly installed on the outer wall of the insertion rod 51. The insertion rod 51 and the limiting ring 52 are respectively inserted into the inner wall of the positioning groove 23. The positioning groove 23 is in communication with the clamping groove 22. The insertion rod 51 penetrates into the clamping groove 22. One end of the spring 53 is fixedly connected with one side of the inner wall of the positioning groove 23. The other end of the spring 53 is fixedly connected with the limiting ring 52. The outer side of the insertion rod 51 is fixedly connected with a protruding block 54. The inner side of the insertion rod 51 is designed in an inclined manner.

[0030] Through the insertion rod 51 in the limiting assembly 5, the limiting ring 52 and the protruding block 54 can be installed. Since the inner side of the insertion rod 51 is designed in an inclined manner, and the left and right ends of the spring 53 are fixedly connected with the positioning groove 23 and the limiting ring 52, the connecting block 32 is inserted into the mounting groove 21. The bottom of the connecting block 32 slides along and presses the insertion rod 51, driving the limiting ring 52 to slide outward along the positioning groove 23. At this time, the spring 53 is compressed. When the insertion rod 51 coincides with the insertion hole 33, the spring 53 pushes the limiting ring 52 to drive the insertion rod 51 to reset. The insertion rod 51 is inserted into the insertion hole 33, limiting the connecting block 32, thereby being able to freely fix different sizes and shapes of the scraping head 31.

[0031] Referring to Figure 2 , Figure 6 , the outer wall of the handle 1 is provided with a protrusion 11. The inner wall of the anti-skid sleeve 4 is provided with a groove matched with the protrusion 11. The protrusion 11 is located in the groove. The anti-skid sleeve 4 is arc-shaped, and the anti-skid sleeve 4 is made of rubber material. The outer wall of the anti-skid sleeve 4 is designed in a concave-convex manner.

[0032] The convex 11 is arranged on the outer wall of the handle 1, which can limit the anti-skid sleeve 4 and avoid the anti-skid sleeve 4 from slipping. Since the anti-skid sleeve 4 is made of rubber material, the rubber can be elastically deformed under stress, which can increase the actual contact area with the contact surface, improve the static friction, and since the anti-skid sleeve 4 is arc-shaped and the outer wall of the anti-skid sleeve 4 is designed in a concave-convex shape, the anti-skid sleeve 4 can not only improve the comfortable feeling and reduce hand fatigue during use of the device, but also avoid the slipping phenomenon and improve the safety.

[0033] During work, the mounting seat 2 can be installed through the handle 1. Since the top of the mounting seat 2 is provided with the mounting groove 21, the connecting block 32 is inserted into the mounting groove 21, and the limiting component 5 is inserted into the insertion hole 33, the connecting block 32 can be limited, and then different sizes and shapes of the scraping head 31 can be freely fixed.

[0034] Conversely, the limiting component 5 is stretched outward to be separated from the insertion hole 33, the connecting block 32 is released from the limitation, and the connecting block 32 and the scraping head 31 are taken out from the mounting groove 21, which solves the problem that the scraping knife integrated design cannot meet the use requirements in different situations, and when the scraping head with different sizes or shapes is needed, multiple scraping knives must be purchased, which brings inconvenience to use and storage.

[0035] Since the outer wall of the handle 1 is provided with the anti-skid sleeve 4, the anti-skid sleeve 4 can not only improve the comfortable feeling and reduce hand fatigue during use of the device, but also avoid the slipping phenomenon and improve the safety.

[0036] The three clamping blocks 34 can be installed through the connecting block 32. Since the top of the mounting seat 2 and the outer wall of the mounting groove 21 are provided with three clamping grooves 22, the three clamping blocks 34 are inserted into the three clamping grooves 22 when the scraping head 31 is installed, the connecting block 32 is located in the mounting groove 21, and the insertion hole 33 and the limiting component 5 are flush, which facilitates the limiting component 5 to limit the connecting block 32.

[0037] The limiting ring 52 and the convex block 54 can be installed through the insertion rod 51 in the limiting component 5. Since the inner side of the insertion rod 51 is designed in an inclined shape, and the left and right ends of the spring 53 are fixedly connected with the positioning groove 23 and the limiting ring 52, the connecting block 32 is inserted into the mounting groove 21, the bottom of the connecting block 32 slides along the insertion rod 51 and presses the insertion rod 51 to drive the limiting ring 52 to slide outward along the positioning groove 23. At this time, the spring 53 is compressed, and when the insertion rod 51 coincides with the insertion hole 33, the spring 53 pushes the limiting ring 52 to drive the insertion rod 51 to reset, the insertion rod 51 is inserted into the insertion hole 33, the connecting block 32 is limited, and then different sizes and shapes of the scraping head 31 can be freely fixed.

[0038] The convex 11 is arranged on the outer wall of the handle 1, which can limit the anti-skid sleeve 4 and avoid the anti-skid sleeve 4 from slipping. Since the anti-skid sleeve 4 is made of rubber material, the rubber can be elastically deformed under stress, which can increase the actual contact area with the contact surface, improve the static friction, and since the anti-skid sleeve 4 is arc-shaped, the outer wall of the anti-skid sleeve 4 is designed in a concave-convex shape, so that the anti-skid sleeve 4 can not only improve the comfortable feeling and reduce hand fatigue during use, but also avoid the slipping phenomenon and improve the safety.

[0039] In summary, the connecting block 32 is inserted into the mounting groove 21, the limiting assembly 5 is inserted into the insertion hole 33, the connecting block 32 is limited, and the scraping head 31 is fixed, so that the scraping head 31 of different sizes or shapes can be freely replaced, which is convenient for use and storage.

[0040] Meanwhile, the contents not described in detail in the specification all belong to the prior art known to those skilled in the art.
