[0006] In some modified embodiments of the present application, the finger roller also includes: the roller has a partial shape change, including diameter change, fillet or chamfer; and / or the outer surface of the roller is physically and / or chemically treated, including grinding, polishing, coating, plating or modification; and / or a shell is coupled to the outside of the roller body as a protective layer or a new outer surface; and / or the roller body is replaced with a quasi-cylindrical body, and the quasi-cylindrical body includes a spindle body or a dumbbell body.

[0007] In some modified embodiments of the present application, the connection form of the connecting part includes one or more combinations of bearing connection, hinge connection, ball and socket connection, pin connection, sliding connection, and fixed connection.

[0008] In some modified embodiments of the present application, the finger pinching portion also has a plate-shaped end portion for the fingertip to fit and apply pressure and friction. The finger pinching portion also has a plate-shaped end portion for the fingertip to fit and apply pressure and friction.

[0009] The present application provides a method for using a finger-kneading roller, characterized in that the method for using the roller comprises: Two fingers pinch the two finger pinches relative to each other, so that the finger pads fit the ends of the finger pinches and apply pressure and friction thereto, the horizontal component of the friction force pushes the roller to roll around the axis on the target working surface, and the vertical component of the friction force causes the roller to produce a rolling effect on the target working surface, and the superposition of the above forces can cause the roller to roll and crush at the same time.

[0010] The present application also provides a method for using a finger-kneading roller, characterized in that the method comprises: The finger roller is used in conjunction with a wiping part before, during or after use; the wiping part includes a wiping tool and / or an attachment, the wiping tool is a material or component used to remove substances adsorbed on the roller surface or to evenly distribute the adsorbed substances, and the attachment is a consumable with a specific function that is adsorbed onto the roller surface or the wiping tool through physical or chemical action; the wiping tool is first dipped in or smeared with the attachment, and then smeared with the outer surface of the roller; or, the outer surface of the finger roller is first dipped in or smeared with the attachment, and then smeared with the wiping tool; or, the outer surface of the finger roller is directly dipped in or smeared with the attachment and applied to a work surface; or, the outer surface of the finger roller is directly smeared with the wiping tool.

Fingers are one of the most flexible parts of the human body. They have a complex bone structure, numerous joints, and rich muscle and nerve distribution, which enables human fingers to perform fine movements, such as grasping, pinching, writing, etc. At the same time, the sensory nerve endings on the fingertips are very dense, making the fingers very sensitive to touch, which is very important for sensing the environment and force feedback. Therefore, although the finger-pinch roller has a smaller working surface range and applied pressure than the traditional handle roller, it has a more dexterous operating experience. For example, in the field of beauty and massage, the finger-pinch roller is more precise, delicate and gentle when applying cosmetics or health products. For example, in the field of medicine and medical treatment, using a finger-pinch roller to apply ointment to the damaged or diseased surface of the body can not only prevent infection, but also keenly perceive force feedback to reduce the patient's pain.

[0013] The above characteristics make this application show its novelty, creativity and practicality in many aspects such as investment, production, transportation, user experience, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] In order to make the purpose, technical scheme and beneficial effects of the implementation methods of the present application clearer, the technical scheme in the implementation methods of the present application will be clearly and completely described below in conjunction with the drawings in the implementation methods of the present application. Obviously, the described implementation methods are part of the implementation methods of the present application, rather than all the implementation methods. Based on the implementation methods in the present application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application. Therefore, the following detailed description of the implementation methods of the present application provided in the drawings is not intended to limit the scope of the present application for protection, but merely represents the selected implementation methods of the present application.

[0017] In the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Embodiment 1

[0018] The finger-kneading roller in the first embodiment of the present application is as follows: Figure 1-1 to Figure 1-4 As shown, the roller body 10 , an integral connecting portion 20 , a first finger pinching portion 31 , and a second finger pinching portion 32 are included.

[0019] The roller body 10 has an outer surface 11, a roller edge 12, a roller side 13, and a roller interior 14, and can be integrally formed using a single material, including but not limited to plastic, rubber, metal, glass, ceramic, wood or felt; a composite process can also be used to couple a new shell to the outer surface as an outer surface or protective layer, and the coupling method can be a fixed connection or a movable connection. The material of the shell can be the same as that of the roller body, or a flexible material or an absorbent material can be used, including but not limited to microfiber material, sponge, soft rubber, activated carbon, diatomaceous earth or natural fiber material; in some embodiments, the roller side 13 can be concave inward or convex outward; in other embodiments, the roller interior 14 can be a hollow structure or a frame structure.

[0020] Preferably, the roller adopts a cylindrical outer surface as the outer surface 11 to facilitate rolling and rolling. In some embodiments, a quasi-cylindrical outer surface may also be adopted. The so-called quasi-cylindrical object refers to an object whose overall shape is similar to a cylinder, with a roughly circular cross-section, and a slight curvature or asymmetry in some parts, such as a spindle body, a dumbbell body, etc.; when there are special requirements, the outer surface 11 of the roller may also be physically and / or chemically treated, including but not limited to grinding, polishing, coating, plating or modification; wherein the coating or plating, for example, plating may refer to a thin layer of metal or plastic applied to the metal surface of certain objects, usually for aesthetic purposes or storage purposes. The plating may be obtained by electrolysis, chemistry, etc., to form a protective film, improve surface properties, and enhance the corrosion resistance, wear resistance and decorative properties of the object. Coating can be applied by spraying or other methods, and a viscous liquid is applied to the surface of an object, and a thin film is formed after solidification, which is mainly used for improving surface characteristics, protection, insulation and decoration. Among them, the modification refers to the change of the properties of a material by physical or chemical means to meet specific use requirements, such as obtaining non-stickiness or reducing surface energy. For example, common types of modified materials include reinforcing agents, flame retardants, antistatic agents, antioxidants, etc., which can improve the strength, hardness, heat resistance and weather resistance of materials such as plastics.

[0021] The roller edge 12 is the transition part between the roller outer surface 11 and the roller side surface 13. Its shape will affect the use effect to a certain extent. It can be modified by rounding 15, chamfering 16, reducing diameter 17, etc. Figure 3-1 to Figure 3-6 As shown; preferably, the rounded corners 15 allow a smooth transition between the outer surface 11 and the side surface 13 of the roller, so that the effect of applying and rolling at the edge 12 of the roller is more uniform, such as when applying plastic materials or massaging the body skin.

[0022] The integral connection part 20 is a component that connects the roller body 10 and the first finger pinch part 31 and the second finger pinch part 32, and it provides connection, support and rolling functions at the same time; Figure 1-1 to Figure 1-4As shown, in this embodiment, a cylindrical rod is used as the integral connection part 20, and the round rod passes through the axial direction of the roller body 10, one end of which is connected to the first finger pinching part 31, and the other end is connected to the second finger pinching part 32. The connected components 20, 31 and 32 can rotate relative to the roller body 10; the connection method between the round rod and the first finger pinching part 31 and the second finger pinching part 32 is a fixed connection, including but not limited to bonding, welding, threaded fastening, snap fastening or mortise and tenon joints. In some embodiments, the connection method can be a movable connection, such as a hinge, a ball joint or a pin, etc. In other embodiments, the connection part and the finger pinching part can also be formed in one piece; The connection method between the integral connection part 20 and the roller body 10 given in this embodiment is a simple mode. In other embodiments, when it is necessary to improve stability and reduce rolling friction, bearing connection, hinge connection, ball socket connection, pin connection, sliding connection, etc. can be used; at the same time, in order to make the roller rotate freely and not easy to fall off, interference fit, clearance fit and other matching methods or positioning devices such as shoulder / step, locking nut, retaining ring / circlip, stop ring, etc. can be used. In other embodiments, in order to save costs and simplify production, the roller body, the connection part and the finger pinch part can also be formed in one piece. In this case, there is no movable mechanism inside the roller, and the position where sliding friction is generated during rotation is the finger pinch part end face 33 and the finger 34.

[0023] Preferably, in the present embodiment, the first finger pinch portion 31 and the second finger pinch portion 32 have a circular plate-shaped end portion 33 for the finger pads to fit and apply pressure and friction; in some embodiments, the end surface 33 of the finger pinch portion may be plate-shaped, where the so-called plate-shaped means that the overall shape of the object is similar to a flat plate, but there are some additional structures or design units, such as edge deformation, bending or uneven surface, such as a circular plate, a square plate, a polygonal plate, a plate with a convex and concave surface, or a plate with irregularly deformed edges, etc.; in other embodiments, the end surface 33 of the finger pinch portion may be surface treated to make the finger pinching more stable and have a better feel, such as etching a groove texture, applying a film or gluing a surface, etc. Embodiment 2

[0024] In the second embodiment, another type of hand-kneading roller is also provided. Figure 2-1 and Figure 2-2 As shown, the roller body 10 and the first finger pinching portion 31 and the second finger pinching portion 32 have the same features as those in the first embodiment, but the connecting portion of the roller is the first connecting portion 21 and the second connecting portion 22, which are respectively coupled to the roller side 13 and extend to the roller interior 14 but are not connected through; In this example, the first connecting portion 21 and the second connecting portion 22 are two cylindrical short rods, and the connection method between them and the finger pinching portion is the same as the feature in the first embodiment; and the coupling between them and the roller body 10 is independent on both sides of the roller. Preferably, two short rods are respectively inserted into the roller interior 14 for a distance to provide connection, support and rolling functions; This embodiment provides a simple mode of connection. In some embodiments, when it is necessary to improve stability and reduce rolling friction, bearing connection, hinge connection, ball and socket connection, pin connection, sliding connection, etc. can be used; at the same time, in order to make the roller rotate freely and not easy to fall off, interference fit, clearance fit and other fitting methods or positioning devices such as shoulders / steps, locking nuts, retaining rings / circlips, and stop rings can be used. Embodiment 3

[0025] In this embodiment, the finger roller is used in the field of thermal management to pre-spread thermal paste. Thermal paste (or heat dissipation paste) is a filled thermal interface material with good thermal conductivity. The material is paste-like or liquid, has a certain viscosity and fluidity, and has no obvious granularity on the surface. The common type of thermal paste is made of thermally conductive fillers filled in a polymer matrix, has a dispersed phase structure, and its thermal conductivity is often dominated by the thermally conductive fillers. There are two traditional ways to apply thermal paste: one is direct pressure packaging method, such as spot coating, five-point method, X-shaped coating method, etc., but these coating methods still have problems: ① It is difficult to apply the right amount without pre-spreading, and overflow may occur; ② It is difficult to avoid enclosing microbubbles; ③ It relies on the pressurization performance of the buckle; the second is pre-spreading and then packaging. Common coating tools include plastic scrapers, silicone rubber finger sleeves, cotton swabs, etc., which still have many problems. For example, for plastic scrapers, ① the scraper requires high skills to use, and it is easy to produce "scratches", "scraping wires", and "peeling"; ② It is picky about the type of thermal paste. The higher the viscosity, the more difficult it is to apply; ③ It is difficult to continuously and stably pressurize the thermal paste, and it is not easy to continuously and stably thin it, so it is difficult to form a high-quality uniform layer and a flat layer.

[0026] The present embodiment provides a pre-spreading tool for thermal paste, which can improve the uniformity, smoothness, compactness, adhesion, cohesion, and resilience of the thermal paste, and obtain a pre-spreading layer with high thermal conductivity, low running-in period, high durability, and improved pit pumping capacity, satisfying the user's pursuit of simplicity and extreme high-quality application, overcoming the thermal paste's picky radiator assembly, and achieving high robustness of the application tool for thermal paste spreading.

[0027] The technical solution of this embodiment is as follows: Figure 4As shown, a roller body 10 has a cylindrical smooth outer surface 11 for coating and / or rolling, and can be repeatedly rolled on a working surface 41 to spread the thermal paste and adjust the dispersed phase structure of the thermal paste; a first finger pinch portion 31, a second finger pinch portion 32 and a connecting portion 20 thereof, wherein the connecting portion 20 is an integral body that runs through the axial direction of the roller, and in other embodiments may be two components independently coupled to the axial direction of the roller; the first finger pinch portion 31 and the second finger pinch portion 32 are configured as components coupled to the connecting portion 20 and extending outward along the axial direction of the roller, and are used for two fingers 40 to relatively pinch the two finger pinch portions and push the roller to move around the axis.

[0028] In some modified embodiments of the present application, the finger pinch roller also includes: the roller part also has a shape change, including diameter change, fillet or chamfer; and / or, the outer surface of the roller is physically and / or chemically treated, including grinding, polishing, coating, plating or modification; and / or, a shell is coupled to the outside of the roller body as a protective layer or a new outer surface, and its material includes but is not limited to polytetrafluoroethylene, high-density polyethylene, nanotechnology coating, silicone coating or ceramic coating; and / or, the roller body is replaced with a cylindrical body, and the cylindrical body includes a spindle body or a dumbbell body. In some other modified embodiments of the present application, the connection form of the connecting part includes a combination of one or more of a bearing connection, a hinge connection, a ball and socket connection, a pin connection, a sliding connection, and a fixed connection. In some modified embodiments of the present application, the finger pinch part also has a plate-shaped end for the fingertip to fit and apply pressure and friction, and the plate-shaped includes a circular plate, a square plate, a polygonal plate, a plate with a convex and concave surface, or a plate with an irregularly deformed edge.

[0029] The technical principles and beneficial effects of this embodiment are as follows: The fundamental reason why the scraper produces the many negative technical problems mentioned above is its operation method and mechanism. At the macro level, the scraper obtains sliding friction and shear slip force by "sticking and pulling". Excessive shear slip force will bring negative problems, such as scraping and peeling. At the same time, sliding friction depends on the contact area and friction coefficient, and for thermal paste with high viscosity, it is easy to adhere to more substances when it is detached; at the micro level, shear stress can only make the solid particles in the dispersed phase spread horizontally, but cannot achieve the effect of making it denser; relatively speaking, the roller obtains rolling friction and vertical pressure by "repeated rolling". Due to its smaller friction, smaller contact area, larger pressure and high-frequency repetitive operation, it reduces the negative effect of shear force while increasing the compacting effect of pressure. This can be compared to the "rolling noodles" and "road roller" in reality, or the Poisson effect (lateral deformation effect) in plastic mechanics to explain the effect of vertical pressure on horizontal spreading and thinning.

[0030] In the actual operation process, the finger-pinch roller has a cylindrical smooth outer surface. By repeatedly rolling on the working surface, a low-disturbance basic pre-paving layer can be obtained, and through a repeatable rolling friction method, the thixotropy of the thermal paste is fully utilized to adjust the dispersed phase structure inside, on the top and bottom surfaces of the thermal paste, so that the thermal paste can achieve high continuity, high stability and high adaptability of the dispersed phase structure under the influence of its own thixotropy, so that the spread layer obtained under the previous rolling will form a better rolling layer after the next rolling. This rolling method can improve the adaptability of thermal paste paving. During the entire process of thermal paste paving, especially in the later stage of paving or even the final stage, it can be repeatedly rolled at a faster speed and with any pressure of the hand without worrying about the sensitivity of the scraper to pressure and shear force. Even in the later stage of spreading or even the final stage, the pre-spreading layer is already thin, uniform in thickness and can be more tightly attached to the surface of the heat source, and it can continue to be rolled repeatedly. However, the pre-spreading layer will not be easily disturbed or even partially damaged by subsequent rolling because it is already thin. That is, the thinning and properties of the pre-spreading layer are easily inherited by subsequent rolling, thereby continuously optimizing the thinness, thickness uniformity, and the fit between the bottom surface of the pre-spreading layer and the micro-pits (or excluding gas to build more heat conduction paths). However, the use of a scraper method shows the opposite situation due to its sensitivity to thinness and force.

[0031] Finally, the finger-kneading roller fully adjusted the dispersed phase structure inside, on the top and on the bottom of the pre-spreading layer (such as reduced spacing between fillers, uniform spacing between fillers, redistribution of the skeleton structure of large and small fillers, cohesion, compactness, adhesion and resilience), as well as the flatness and smoothness of the top surface, and the embedding degree of the bottom surface (the degree and proportion to which the pre-spreading layer can overcome the shear force and be embedded in the micro-pits after repeated rolling). Among them, the flatness and smoothness of the top surface can reduce or avoid the closure of micro-bubbles formed after buckling; the embedding degree of the bottom surface can exclude more gas in the micro-pits, thereby forming more heat conduction pathways, and forming a press-embedded anchoring effect, thereby producing a certain negative pressure adsorption effect that resists peeling, which can achieve improved anti-pumping capabilities during the high and low temperature cycles of work. The compactness and cohesion are improved to achieve an improved bonding force of the pre-spreading layer, thereby improving the integrity of the flaky thin layer of the pre-spreading layer. At the same time, the spacing between fillers is reduced, the spacing between fillers is uniform, and the skeleton structure of large and small fillers is re-distributed. The thermal conductivity, cohesion, compactness, adhesion, and resilience of the pre-spreading layer are all improved, and the top surface of the pre-spreading layer presents a certain degree of smoothness and reflectivity. As a result, the running-in period can be predicted and shortened, the attenuation is slowed down, and the thermal conductivity and durability are improved.

[0032] In other embodiments of the present application, the finger-pinching roller is used in the fields of beauty and massage, medicine and healthcare, stationery or chemical industry, and the finger-pinching roller includes a roller body, a finger-pinching part and a connecting part. Preferably, the outer surface or shell of the roller body is made of a flexible material or an adsorptive material.

Optionally, the shape of the roller body is cylindrical, including but not limited to a spindle or a dumbbell. Optionally, engraving, etching, printing, electroplating, chemical plating, machining, photolithography, thermal transfer, decals, 3D printing and other processes are used on the outer surface of the roller body or the new shell to form a specific pattern.
