[0025] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0026] The back scratcher includes a handle 30, a telescopic rod 20, and a scratching head 10. The scratching head 10 is connected to the top of the telescopic rod 20, and the bottom of the telescopic rod 20 is inserted into the handle 30. The handle 30 is provided with a central knob 40, which is used to lock the relative position of the handle 30 and the telescopic rod 20. The scratching head 10 has a rigid end face 11 and a soft end face 13 on its two sides, respectively. The rigid end face 11 has a plurality of hard protrusions 12 protruding outward, and the soft end face 13 has a plurality of soft protrusions 14 protruding outward.

[0027] The aforementioned back scratcher features a telescopic rod 20 and a handle 30 locked together via a central knob 40. Users can adjust the length of the back scratcher to suit different body parts (such as the back and legs), enhancing its flexibility. The plug-in design of the telescopic rod 20 and handle 30, combined with the knob lock, ensures that the back scratcher will not retract accidentally during use, improving safety and reducing the overall length for easy portability. The rigid protrusion 12 on the rigid end face 11 of the scratching head 10 is suitable for strong stimulation, such as scratching under heavy clothing, while the soft protrusion 14 on the soft end face 13 is suitable for sensitive skin or gentle massage, meeting different scenarios and user preferences. This solves the problem that back scratchers are generally non-retractable and inconvenient for scratching different parts of the body.

[0028] In this embodiment, the telescopic rod 20 and the scratching head 10 are an integrated structure. The scratching head 10 is arranged in a ring shape, and a hollow opening 15 is formed in the middle of the scratching head 10.

[0029] The integrated design of the telescopic rod 20 and the scratching head 10 reduces connection points, avoids loosening or breakage caused by frequent adjustments, and extends service life; the hollowed-out opening 15 in the middle of the ring-shaped scratching head 10 reduces the overall weight and also reduces the contact area with the skin, avoiding stuffiness and making it suitable for summer or long-term use.

[0030] In this embodiment, the hard protrusion 12 is a conical protrusion with a rounded top.

[0031] The rigid, cone-shaped protrusion concentrates pressure on the local skin, quickly relieving deep itching (such as mosquito bites); the rounded top avoids sharp edges from scratching the skin, reducing the risk of use.

[0032] In this embodiment, the soft protrusion 14 is a strip-shaped protrusion. The strip-shaped protrusion is arranged laterally, and multiple strip-shaped protrusions are arranged at intervals around the circumference of the soft end face 13. The cross-section of the strip-shaped protrusion is triangular, and its top is a rounded transition.

[0033] The soft, horizontally shaped protrusions are distributed circumferentially, conforming to the skin's curves during use and providing gentle friction over a large area, suitable for relaxing muscles or soothing dry skin; reducing skin irritation: the rounded top design of the triangular cross section disperses pressure and prevents discomfort caused by excessive deformation of the soft protrusions 14.

[0034] In this embodiment, one side of the scratching head 10 is recessed inward to form an annular inner groove 16, and an annular soft block 17 is installed on the annular inner groove 16. The soft block 17 forms a soft end face 13 on the outward side, and the soft protrusion 14 and the soft block 17 are an integrated structure.

[0035] The main body of the scratching head 10 can be made of rigid plastic in one piece, while the soft block 17 can be injection molded separately, simplifying the production process; in this way, one rigid end face 11 and one soft end face 13 of the scratching head 10 can be formed.

[0036] In this embodiment, the bottom of the annular inner groove 16 is provided with an outer protruding ring 161 and an inner protruding ring 162. The inner protruding ring 162 and the inner sidewall of the annular inner groove 16 form an inner slot 163. The inner protruding ring 162 and the outer protruding ring 161 form a middle slot 164. The outer protruding ring 161 and the outer sidewall of the annular inner groove 16 form an outer slot 165. The soft block 17 is recessed inward to form an outer ring groove and an inner ring groove corresponding to the outer protruding ring 161 and the inner protruding ring 162. The soft block 17 is embedded in the annular inner groove 16 and is connected to the scratching head 10. The outer sidewall of the soft block 17 abuts against the outer sidewall of the annular inner groove 16.

[0037] The outer protruding ring 161 and the inner protruding ring 162 cooperate with the outer ring groove and the inner ring groove of the soft block 17 to form a multi-level snap-fit ​​structure, ensuring that the soft block 17 will not fall off during scratching; precise positioning: the distribution of the inner slot 163, the middle slot 164 and the outer slot 165 makes it possible to install the soft block 17 without additional alignment, thus improving assembly efficiency.

[0038] In this embodiment, the handle 30 has a storage cavity with a top opening, and the bottom outer periphery of the telescopic rod 20 is provided with an anti-detachment limiting ring 21, with the bottom of the telescopic rod 20 inserted into the storage cavity.

[0039] Portability optimization: The telescopic rod 20 is completely retracted into the handle 30 cavity, reducing the storage volume and making it convenient to carry (such as for travel and outdoor use).

[0040] Anti-drop design: The anti-drop limiting ring 21 is engaged with the top of the storage cavity to prevent the telescopic rod 20 from completely detaching from the handle 30.

[0041] In this embodiment, a plurality of threaded clamping pieces 31 are provided on the top opening of the handle 30. The outer side of the threaded clamping pieces 31 has a threaded groove. The plurality of threaded clamping pieces 31 are arranged circumferentially around the top opening of the handle 30 at intervals to form a threaded clamping head. The handle 30 is threadedly connected to the middle knob 40 through the threaded clamping head. A limiting protrusion 32 is provided on the top inner sidewall of the threaded clamping head.

[0042] Quick locking: Multiple threaded clamping plates 31 engage with the threaded knob 40, allowing the telescopic rod 20 to be tightened or released by rotation, making operation convenient.

[0043] Uniform stress distribution: The circumferentially spaced threaded clamping plates 31 uniformly clamp the telescopic rod 20, avoiding local stress concentration that could lead to deformation;

[0044] Anti-detachment design: The top of the threaded clamping head uses the limiting protrusion 32 to engage the anti-detachment limiting ring 21 of the telescopic rod 20 with the top of the storage cavity, preventing the telescopic rod 20 from completely detaching from the handle 30.

[0045] In this embodiment, both the surface of the central knob 40 and the lower surface of the handle 30 are provided with vertical anti-slip textures.

[0046] Anti-slip performance: The vertical anti-slip texture on the surface of the handle 30 and the middle knob 40 increases friction, preventing slippage caused by sweaty hands or unstable grip, and improving operational safety.

[0047] Tactile differentiation: The difference in tactile feel of the anti-slip texture helps users quickly distinguish the handle 30 from the knob position, facilitating blind operation.

[0048] In this embodiment, the bottom of the handle 30 has a rolling inner cavity 33 with a bottom opening, and a rolling massage bead 34 is disposed in the rolling inner cavity 33, with the massage bead 34 at least partially exposed outside the rolling inner cavity 33.

[0049] Functional expansion: The massage beads 34 at the bottom of the handle 30 can be used as an independent massage tool to press acupoints (such as the palm and sole), realizing multiple uses in one product;

[0050] Rolling massage experience: The massage beads 34 rotate freely in the rolling cavity 33, reducing frictional resistance with the skin and providing a smooth massage sensation.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
