[0023] 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.

[0024] Please see Figure 1-6 This utility model provides a technical solution:

[0025] A fascia gun with a retractable handle includes a first connecting post 1, a second connecting post 2 inside the first connecting post 1, a massage head 5 fixedly mounted on the outer surface of the first connecting post 1, a rubber base 4 fixedly connected to the bottom of the second connecting post 2, and a stretching component inside the second connecting post 2. The stretching component is used to drive the first connecting post 1 to extend and retract on the outer surface of the second connecting post 2. The stretching component includes a first connecting block 9, a second connecting block 10, and a third connecting block 11. The first connecting block 9 is fixedly connected to the inner wall of the second connecting post 2, the second connecting block 10 is located inside the first connecting block 9, and the third connecting block 11 is located inside the second connecting block 10. The top of the third connecting block 11 is fixedly connected to the interior of the first connecting post 1. As the third connecting block 11 moves, the first connecting post 1 will extend and retract on the outer surface of the second connecting post 2 because its top is fixedly connected to the interior of the first connecting post 1.

[0026] Furthermore, the extension assembly also includes a first belt 12, a rotating shaft 14, a first pulley 15, and a second pulley 17. The rotating shaft 14 is rotatably connected to the inner wall of the second connecting column 2. Two symmetrically distributed first pulleys 15 are fixedly connected to the outer surface of the rotating shaft 14. The two first pulleys 15 are located outside the first connecting block 9. Two second pulleys 17 are rotatably connected to the top and bottom of the first connecting block 9. A first belt 12 is sleeved between the first pulley 15 and the two second pulleys 17 in the same horizontal direction. The second connecting block 10 is fixedly sleeved with the two first belts 12. The rotation of the drive motor 8 will drive the rotating shaft 14 to rotate together. The rotation of the rotating shaft 14 will drive the two first pulleys 15 on its outer surface to rotate synchronously. The two first pulleys 15 are connected to the second pulleys 17 at the top and bottom of the first connecting block 9 through the first belts 12. Since the first belt 12 is sleeved with the second connecting block 10, the rotation of the first pulleys 15 will drive the second connecting block 10 to move inside the first connecting block 9.

[0027] Furthermore, the top and bottom of the second connecting block 10 are rotatably connected to a third pulley 18, and a second belt 13 is sleeved between the two third pulleys 18. The third connecting block 11 is fixedly sleeved with the second belt 13, and the third connecting block 11 is driven to move synchronously by the second belt 13.

[0028] Furthermore, four mutually symmetrically distributed limiting wheels 16 are rotatably connected to the outer surface of the first connecting block 9, two of which are movably connected to the corresponding first belt 12, and the two limiting wheels 16 and the corresponding first belt 12 are movably connected to each other, which serve as guides and limiters.

[0029] Furthermore, the inner wall of the first connecting block 9 is fixedly connected to two symmetrically distributed first guide rails 19, and the inner wall of the second connecting block 10 is fixedly connected to two symmetrically distributed second guide rails 20. The outer surfaces of the two first guide rails 19 and the two second guide rails 20 are slidably connected to two sliders 21. Four sliders 21 are fixedly connected to the outer surface of the third connecting block 11, and the other four sliders 21 are fixedly connected to the outer surface of the second connecting block 10. The inner walls of the first connecting block 9 and the second connecting block 10 are respectively fixedly connected to two symmetrically distributed first guide rails 19 and second guide rails 20. The outer surfaces of these guide rails are slidably connected to sliders 21. Four sliders 21 are fixedly connected to the outer surface of the third connecting block 11, and the other four sliders 21 are fixedly connected to the outer surface of the second connecting block 10. While the belt drives the system, the guide rail and slider system also provides a stable movement path for the extension component.

[0030] Furthermore, two symmetrically distributed limiting grooves 7 are provided at the bottom of the first connecting post 1, and two symmetrically distributed limiting blocks 6 are fixedly connected to the outer surface of the second connecting post 2. The interior of the two limiting grooves 7 is slidably connected to the corresponding limiting blocks 6. The limiting grooves 7 are designed at the bottom of the first connecting post 1, while the limiting blocks 6 are fixedly installed on the outer surface of the second connecting post 2. When the first connecting post 1 extends or retracts relative to the second connecting post 2, the cooperation between the limiting grooves 7 and the limiting blocks 6 can ensure that the first connecting post 1 moves along the correct trajectory.

[0031] Furthermore, a protective box 3 is fixedly installed on the outer surface of the second connecting column 2. A door is hinged to the outer surface of the protective box 3. A drive motor 8 is fixedly installed on the outer surface of the second connecting column 2. The output end of the drive motor 8 is fixedly connected to the rotating shaft 14. The drive motor 8 is located inside the protective box 3. The door is hinged to the outer surface of the protective box 3, which can protect the motor from interference and damage from the external environment.

[0032] Working principle: When the operator needs to use the fascia gun with its extendable handle, and when the user needs to adjust the length of the fascia gun handle, the drive motor 8 on the outer surface of the second connecting post 2 is activated. The rotation of the drive motor 8 will drive the rotating shaft 14 to rotate as well. The rotation of the rotating shaft 14 will drive the two first pulleys 15 on its outer surface to rotate synchronously. These two first pulleys 15 are connected to the second pulleys 17 at the top and bottom of the first connecting block 9 via the first belt 12. Since the first belt 12 is sleeved with the second connecting block 10, the rotation of the first pulleys 15 will drive the second connecting block 10 to rotate. The first connecting block 9 moves internally, while a second belt 13 is sleeved between the third pulley 18 rotatably connected to the top and bottom of the second connecting block 10. The second belt 13 is fixedly sleeved with the third connecting block 11. Therefore, when the second connecting block 10 moves, it drives the third connecting block 11 to move synchronously via the second belt 13. To ensure the stability of the extension assembly during movement, two symmetrically distributed first guide rails 19 and second guide rails 20 are fixedly connected to the inner walls of the first connecting block 9 and the second connecting block 10, respectively. The slider 2 is slidably connected to the outer surface of these guide rails. 1. Four sliders 21 are fixedly connected to the outer surface of the third connecting block 11, and the other four sliders 21 are fixedly connected to the outer surface of the second connecting block 10. While the belt drives the transmission, the guide rail slider system also provides a stable moving path for the extension component. In order to maintain the stability and accuracy of the first belt 12 during the transmission process, four mutually symmetrically distributed limit wheels 16 are rotatably connected to the outer surface of the first connecting block 9. Two of the limit wheels 16 are movably connected to the corresponding first belt 12, which play a guiding and limiting role. As the third connecting block 11 moves, since its top is fixedly connected to the inside of the first connecting column 1, the first connecting column 1 will extend and retract on the outer surface of the second connecting column 2. The limit groove 7 is designed at the bottom of the first connecting column 1, and the limit block 6 is fixedly installed on the outer surface of the second connecting column 2. When the first connecting column 1 extends and retracts relative to the second connecting column 2, the cooperation between the limit groove 7 and the limit block 6 can ensure that the first connecting column 1 moves along the correct trajectory. During the entire working process, the drive motor 8 is located inside the protective box 3. The outer surface of the protective box 3 is hinged with a box door, which can protect the motor from interference and damage from the external environment.
