[0002] As people's living standards improve, using tablets and mobile phones has become a modern lifestyle. Tablets and mobile phones are very portable, but their only drawback is the lack of a fixed support, which is one of the reasons why many people suffer from cervical spondylosis. Holding them for extended periods to watch videos causes fingers to feel sore and strained. However, current phone stands are relatively simple in function; although they are carried with the phone, they offer little beyond serving as a stand. Summary of the Invention

[0003] One objective of this invention is to provide a multifunctional mobile phone holder that combines a portable knife with a mobile phone holder, allowing the portable knife to function as an expandable support leg. This not only provides support for the mobile phone but also provides a concealed portable knife for easy cutting.

[0004] Another objective of this invention is to provide a multifunctional mobile phone holder that, by accommodating various items within the holder, makes reasonable use of the holder's space and enhances its expandability.

[0005] Another objective of this invention is to provide a multifunctional mobile phone holder that, by assembling the blade and elastic element on the same plane, greatly reduces the thickness of the portable knife while achieving damped sliding and positioning of the blade, making it convenient to use and easier to carry due to its thin structure.

[0042] like Figures 1-2 The illustration shows a mobile phone holder 2. The multi-functional mobile phone holder 2 includes a first leg 40, a second leg 50, and a blade 1. The second leg 50 is rotatably connected to the first leg 40. The first leg 40 has a connecting portion 41 and a receiving cavity 44. The connecting portion 41 is located on the back of the first leg 40, allowing the first leg 40 to adhere to the back of the mobile phone. The receiving cavity 44 is located on the front of the first leg 40 to accommodate the second leg 50. The second leg 50 has a slot 51, in which the blade 1 is detachably engaged. The thin-blade blade 1 is inserted into the slot. By combining the portable blade 1 and the mobile phone holder 2, the portable blade 1 serves as an expandable leg, providing not only support for the mobile phone but also a concealed portable blade for convenient cutting.

[0043] like Figures 3-9The cutter 1 shown includes a housing 10, a blade 20, and an elastic element 30. The housing 10 has an internal channel 101, an opening 102, a guide groove 103, and multiple limiting parts 126. The opening 102 is located at the front end of the internal channel 101. The limiting parts 126 are disposed in at least one inner sidewall on both sides of the internal channel 101 and are opened along the horizontal direction of the inner sidewall. The guide groove 103 is opened along the longitudinal axis on the upper surface of the housing 10 and connects the internal channel 101 to the outside. The blade 20 has a cutting surface 21 and a positioning groove 23 located on the opposite side of the cutting surface 21. The positioning groove 23 is located on the rear side of the blade 20 and faces the limiting parts 126 of the housing 10. The elastic element 30 is deformably disposed in the positioning groove 23 and extends from the positioning groove 23 toward the limiting parts 126, so that the blade 20 can be slidably installed in the internal channel 101 at a fixed point. Therefore, its structure is simple and compact, without the need for complex structures and components, realizing the planar structure design of the tool 1, simplifying the design structure, making the tool thickness as thin as possible, making it easy to carry, and at the same time realizing the fixed-point holding of the extension position of the blade 20.

[0044] In some embodiments, the housing 10 further includes a chamfer 105 and a recess 106. The chamfer 105 is obliquely formed at one corner of the housing 10, and the recess 106 is formed on the outer side wall of the housing 10. The recess 106 and the chamfer 105 are adjacent to each other, and the chamfer 105 and the recess 106 allow the tool to be inserted into the slot 51. The slot 51 structure of the second support 50 can be an SD card slot. The chamfer 105 and the recess 106 are close to the front end of the housing 10, so that the opening 102 extends deep into the slot 51, increasing the safety of use.

[0045] In some embodiments, the connecting portion 41 is magnetically annularly disposed on the back of the first support leg 40. By first attaching a magnetic element to the back of the phone and then connecting the connecting portion 41 to the magnetic element, the mounting direction of the phone holder 2 can be rotated, facilitating adjustment of the support angle. Figure 2 As shown.

[0046] In some embodiments, the blade 20, the elastic element 30, and the limiting portion 126 of the housing 10 are located on the same plane, making the tool 1 tend to have a thin-plane structure. The upper surface of the blade 20 faces the guide groove 103. By applying a thrust to the blade 20 in the guide groove 103, the blade 20 can extend outward or retract inward from the opening 102 of the housing 10. At the same time, the deformation of the elastic element 30 enables the blade 20 to slide in a damped fixed-point manner in the internal channel 101, which helps the blade maintain its extended length and greatly reduces the thickness of the tool 1. Thus, by assembling the blade 20 and the elastic element 30 on the same plane, the thickness of the portable tool 1 is greatly reduced, while the damped sliding and positioning of the blade 20 are achieved. This makes it convenient to use, and the thin structure makes it easier to carry.

[0047] In other words, by installing the elastic element 30 inside the blade 20, the blade 20 and the limiting part 126 are on the same plane, thereby achieving a planar thin structure of the tool 1. This avoids the use of a multi-layer three-dimensional structure of actuators, springs and housing teeth. By embedding the elastic element 30 inside the blade 20, traditional actuator accessories are reduced, greatly reducing the thickness of the portable tool and making it easy to carry.

[0048] In some embodiments, the limiting portion 126 has a concave arc-shaped structure. The limiting portion 126 is disposed at intervals in the inner wall of one side along a substantially horizontal direction. The inner wall of the other side is in contact with the cutting surface 21 of the blade 20. A preset distance 120 is provided between adjacent limiting portions 126. The preset distance 120 is suitable for the fixed-point sliding of the blade 20 and maintaining the extended position, thereby preventing shaking and facilitating cutting.

[0049] The housing 10 includes an upper housing 11 and a lower housing 12. A guide groove 103 is formed in the upper housing 10 along the longitudinal axis, and an internal channel 101 is formed in the lower housing 12. A continuously recessed limiting part 126 is provided along the horizontal inner sidewall of the internal channel 101. In other words, the lower housing 12 is provided with a first inner sidewall 122 and a second inner sidewall 123. The internal channel 101 is formed between the first inner sidewall 122 and the second inner sidewall 123. The limiting part 126 is formed at least in the first inner sidewall 122 and / or the second inner sidewall 123. As needed, two elastic members 30 can be used and the positioning groove 23 can be formed on the rear side of the cutting surface 21 of the blade 20. The rear side of the cutting surface 21 cannot extend out of the housing 10.

[0050] Preferably, the limiting part 126 is evenly and continuously distributed along the first inner sidewall 122 to form a generally semi-circular arc tooth structure. The second inner sidewall 123 contacts the cutting surface 21 of the blade 20. The positioning groove 23 is located on the rear side of the blade 20 and faces the first inner sidewall 122. The cutting surface 21 of the blade 20 contacts the first inner sidewall 122 on the opposite side to maintain the stability of the blade 20 in the internal channel 101 and prevent shaking.

[0051] In some embodiments, the limiting portion 126 is provided with a first inclined arc surface 127 and a second inclined arc surface 128. The first inclined arc surface 127 and the second inclined arc surface 128 extend inclinedly from the inner sidewall inward, so that the inner diameter of the limiting portion 126 gradually decreases from the outside to the inside, thereby facilitating the formation of a compression limit with the elastic member 30 and achieving an effective damping effect.

[0052] In some embodiments, the elastic member 30 is provided with a deformation cavity 31, a pair of elastic inclined sections, a connecting section 34, and a pair of positioning sections 35. The elastic inclined sections are respectively inclinedly connected to the connecting section 34 and the positioning section 35. The positioning section 35 extends horizontally outward integrally from the bottom end of the elastic inclined section and abuts against the bottom of the positioning groove 23. The connecting section 34 and the top end of the elastic inclined section are integrally connected. The deformation cavity 31 is formed between the connecting section 34 and the elastic inclined section, so that the top of the elastic member 30 can deformably protrude into the limiting part 126. Thus, when the top of the elastic member 30 extends into the limiting part 126, the first inclined arc surface 127 and the second inclined arc surface 128 compress the top of the elastic member 30, thereby creating resistance to the sliding of the blade 20. The resistance is suitable for the pushing force of an adult's fingertip, making it easy for an adult to smoothly push the blade with the pushing force of their fingertip. The resistance should not be too small to prevent children from accidentally pushing and injuring themselves.

[0053] In some embodiments, the elastic element 30 is generally V-shaped, the connecting section 34 is basically straight, and the elastic inclined section has a first elastic inclined section 32 and a second elastic inclined section 33. The first elastic inclined section 32 and the second elastic inclined section 33 are symmetrically bent to connect the connecting section 34 and the positioning section 35. Thus, the elastic element 30 has a multi-fold structure, and the connecting section 34 is not an arc structure to prevent the rebound force of the connecting section 34 from being difficult to control. Moreover, an arc structure is more prone to deformation than a straight bending structure and cannot maintain the rebound force, thus reducing the service life of the portable tool. The elastic element 30 cannot be a U-shaped structure to prevent the blade 20 from being unable to push and getting stuck.

[0054] In other words, the elastic element 30 has a multi-fold inverted V-shaped structure. The bottom width of the elastic element 30 is greater than the top width of the elastic element 30. The width between the elastic inclined sections gradually decreases from the connecting section 34 to the positioning section 35, which facilitates the formation of suitable resistance with the limiting part 126. When the elastic element... Figure 7 As shown, only about 5N of pushing force is needed to push the blade, and the pushing process is relatively smooth. However, when the elastic element 30 has a U-shaped structure and the elastic inclined section has a vertical structure instead of an inclined structure, it is difficult to deform. The resistance between the elastic element 30 and the limiting part 126 is too large, requiring about 20N of pushing force to push it. This is difficult for the average adult's fingertip to push, and it is quite strenuous, and may even cause the blade to jam. When the connecting section 34 has an arc-shaped structure, the inner sidewall between the limiting parts 126 is a horizontal structure, which easily causes the connecting section 34 to deform and make it difficult to achieve the expected rebound force. At the same time, the arc structure also easily causes the connecting section 34 to over-enter the limiting part in the early stage, resulting in increased resistance. Later, due to the inability to recover from the deformation, the resistance decreases, causing instability during product use.

[0055] In some embodiments, an operating part 25 is provided on the rear side of the blade 20. The operating part 25 protrudes from the upper surface of the blade 20 toward the guide groove 103. This not only facilitates increasing the friction between the operator's fingertip and the upper surface of the blade 20 for pushing the blade 20, but also helps limit the extension length of the blade 20 from the housing 10. The protruding position of the operating part 25 prevents the blade 20 from continuing to extend outward, ensuring the cutting stability of the blade 20. Excessive extension length of the blade 20 will cause instability and wobbling during cutting. The size of the operating part 25 is preferably such that it can be covered by the fingertip of an adult's thumb for easy finger pushing.

[0056] The operating part 25 can be a structure with multiple protruding dots, or a diagonal anti-slip structure or a wavy anti-slip structure, which can increase the friction between the fingertip and the upper surface of the blade 20.

[0057] In some embodiments, the shape of the positioning groove 23 is adapted to the deformation space of the elastic member 30, the inner diameter of the positioning groove 23 gradually increases from the outside to the inside, the bottom width of the positioning groove 23 is adapted to the installation of the positioning sections 35 on both sides of the elastic member 30, and the groove depth of the positioning groove 23 is less than the height of the elastic member 30, so that the elastic member 30 can protrude from the positioning groove 23 to the limiting part 126 to form a damping effect.

[0058] In some embodiments, the positioning groove 23 is provided with a groove 231, a pair of positioning inclined surfaces 232, a positioning bottom surface 233, a pair of first straight segments 234 and a pair of second straight segments 235. The width of the groove 231 is smaller than that of the positioning bottom surface 233. The groove 231 faces the limiting part 126. The positioning inclined surfaces 232 obliquely connect the first straight segments 234 and the second straight segments 235. The positioning segments 35 on both sides of the elastic member 30 can elastically abut against the second straight segments 235 and are located above the positioning bottom surface 233. The distance between the groove 231 and the positioning bottom surface 233 is smaller than the height of the elastic member 30. The shape of the positioning groove 23 is suitable for the stable installation of the elastic member 30.

[0059] In some embodiments, the elastic member 30 is formed by bending metal wire. Under normal conditions, the bottom width of the elastic member 30 is smaller than the width of the positioning bottom surface 233 of the positioning groove 23. When the elastic member 30 is squeezed by the limiting part 126, the top end of the elastic member 30 is subjected to the squeezing force, and the positioning segment 35 of the elastic member 30 extends in the direction of the second straight segment 235. When the top end of the elastic member 30 is against the inner wall of the internal channel 101, the elastic member 30 undergoes downward deformation, and the positioning segment 35 continues to extend in the direction of the second straight segment 235. When the top end of the elastic member 30 moves to the next limiting part 126, the elastic member 30 rebounds and is restricted by the limiting part 126.

[0060] In some embodiments, the upper housing 11 and the lower housing 12 are both metal parts. If plastic is used, it may be easy to break, resulting in a shortened service life. The blade 20 is a metal structure and is installed in the internal channel 101. The upper housing 11 and the lower housing 12 can be integrally formed by laser welding or riveting to ensure that there is no excess gap or looseness between the blade 20 and the housing 10. This also helps to maintain the connection stability between the elastic element 30 and the limiting part 126, and achieve long-term stability of the damping effect.

[0061] In some embodiments, the preset distance 120 between the limiting portions 126 is approximately 0.4 mm to 0.9 mm, the radius of the limiting portion 126 is approximately 0.25 to 0.5 mm, the height of the elastic member 30 is approximately 3 mm to 3.2 mm, the width of the positioning segments 35 on both sides of the elastic member 30, i.e., the bottom width of the elastic member 30, is approximately 6.5 to 7.5 mm, and the thickness of the housing 10 is approximately 1 mm to 3 mm. The width of the connecting segment 34 is suitable for partially entering the limiting portion 126, and the first inclined arc surface 127 and the second inclined arc surface 128 respectively abut against the top of the elastic inclined segment of the elastic member 30.

[0062] The preset spacing 120 between the limiting parts 126 can be approximately 0.4mm, 0.5mm, 0.6mm, 0.65mm, 0.7mm, 0.72mm, 0.75mm, 0.77mm, 0.8mm, 0.82mm, 0.85mm, 0.87mm, or 0.9mm; the radius of the limiting part 126 can be approximately 0.25mm, 0.26mm, 0.27mm, 0.28mm, 0.29mm, 0.3mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.37mm, 0.4mm, 0.43mm, 0.46mm, or 0.5mm. When the width of the limiting part 126 increases, the elastic element 30 needs to be enlarged as well, resulting in a larger space required for the positioning groove 23, which can easily weaken the strength of the blade 20.

[0063] Preferably, the preset distance 120 between the limiting parts 126 is 0.8 mm, and the radius of the limiting part 126 is 0.3 mm. When the preset distance 120 is too large, such as reaching 1 mm, the blade 20 is prone to shaking during use, affecting the cutting process.

[0064] The height of the elastic element 30 can be approximately 3mm, 3.02mm, 3.04mm, 3.05mm, 3.06mm, 3.07mm, 3.09mm, 3.1mm, 3.12mm, 3.14mm, 3.15mm, 3.16mm, 3.18mm, or 3.2mm. Under normal conditions, the width of the positioning sections 35 on both sides of the elastic element 30 is approximately 6.5mm, 6.6mm, 6.7mm, 6.8mm, 6.9mm, 7mm, 7.1mm, 7.2mm, 7.3mm, 7.4mm, or 7.5mm. When the height of the elastic element 30 is approximately 3.05mm to 3.15mm, the pushing force is approximately 5 to 10N, allowing for relatively smooth pushing.

[0065] Preferably, the height of the elastic body 30 is approximately 3.1 mm, the depth of the positioning groove 23 is approximately 3 mm, and the width of the positioning sections on both sides of the elastic body 30 is 7 mm.

[0066] In some embodiments, the thickness of the housing 10, i.e. the overall thickness of the portable knife 1, can be approximately 1 mm, 1.1 mm, 1.2 mm, 1.3 mm, 1.4 mm, 1.5 mm, 1.6 mm, 1.7 mm, 1.8 mm, 1.9 mm, 2 mm, 2.2 mm, 2.4 mm, 2.6 mm, 2.8 mm, or 3 mm. The thickness of the housing 10 can be customized as needed and is not limited herein.

[0067] Preferably, the thickness of the shell 10 is approximately 1.4mm to 2mm. The thickness of the shell 10, i.e. the overall thickness of the portable knife 1, can be approximately 1.4mm, 1.45mm, 1.5mm, 1.55mm, 1.6mm, 1.65mm, 1.7mm, 1.75mm, 1.8mm, 1.85mm, 1.9mm, 1.95mm, or 2mm.

[0068] In some embodiments, the blade 20 is provided with a bottle opening 24, which is located on the opposite side of the cutting surface 21 of the blade 20. The bottle opening 24 is located on the front side of the blade 20 relative to the positioning groove 23, so as to be used to open the bottle cap. The housing 10 further includes a hanging hole 104, which is opened at one corner of the rear end of the housing 10 for hanging on a key ring.

[0069] The shell 10 can be a right-angle structure, a rounded corner structure, or an oblique corner structure.

[0070] In use, first install the phone holder 2 onto the back of the phone via the connecting part 41. The blade 1 is then elastically inserted into the slot 51 of the second support leg 50. When supporting the phone, open the second support leg 50 outwards, allowing the outer end of the blade 1 to rest against a table or other platform. When cutting an object, remove the blade 1 from the slot 51, press the operating part 25 with the pad of your thumb, and apply pushing force to extend the blade 20 along the internal channel 101 from the opening 102, overcoming the squeezing resistance between the top of the elastic member 30 and the limiting part 126 of the inner wall, thus... The blade 20 slides at a fixed point, achieving a damped pushing feel. When the finger stops pushing, the top of the elastic element 30 is squeezed into the limiting part 126, which keeps the blade 20 in the position of the internal channel 101, preventing the blade 20 from retracting or wobbling during cutting. It also helps to keep it in the retracted position, preventing the blade 20 from suddenly loosening and extending, thus improving the safety of using the portable knife 1. When the operating part 25 abuts against the front end of the guide groove 103, the blade 20 reaches its maximum extension position, preventing the knife 1 from extending too far and causing wobbling during cutting. Since the elastic element 30 is installed in the positioning groove 23 of the blade 20, the actuator of the traditional utility knife is eliminated, so that the blade 20, the elastic clip 30 and the limiting part 126 are on the same horizontal plane, which helps the portable knife 1 to meet the requirements of a sheet shape and is easy to carry. At the same time, the bottle opening 24 on the portable knife 1 also helps to open the bottle cap. After use, the knife 1 is placed in the slot 51.

[0071] In some embodiments, such as Figures 12-13 As shown, the first leg 40 is further provided with a storage groove 42, which is opened on the upper surface of the first leg 40. The first leg 40 is further provided with a clamping part 421, a locking member 43, and a locking groove 422. The locking member 43 is elastically installed in the locking groove 422, which is located on at least one side of the storage groove 42. The clamping part 421 is disposed on the inner side of the storage groove 42, and the locking member 43 can elastically lock the clamping part 421, so that the clamping part 421 clamps the cotton swab 5 or toothpick 4, etc.

[0072] In some embodiments, such as Figure 14 As shown, the first leg 40 is further provided with a storage slot 42, which is opened inside the first leg 40 and is suitable for storing the card 3.

[0073] Thus, by accommodating various items in the phone holder 2, it makes reasonable use of the space available for the phone holder and enhances the expandability of the phone holder 2.
