[0028] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0029] Reference Figure 1 , a rotating shaft frame, including a mounting platform 100, a mounting rod 200 and a fixing seat 300. The mounting platform 100 and the mounting rod 200 are preferably integrally formed. Figure 4 , the mounting platform 100 is provided with a first positioning protrusion 110 along the outer circumference of the mounting rod 200, and a second positioning protrusion 120 is provided along the inner circumference of the mounting rod 200; Figure 2The fixing seat 300 includes an upper cavity 310 and a lower cavity 320, and a partition 330 is provided between the upper cavity 310 and the lower cavity 320. The partition 330 is provided with a through hole 331, and the mounting rod 200 can be inserted into the fixing seat 300 through the through hole 331; a first positioning groove 311 is provided on the partition 330 at a position corresponding to the first positioning protrusion 110 in the upper cavity 310, and a second positioning groove 312 is provided at a circumferential position within the through hole 331 of the partition 330, the first positioning protrusion 110 interacts with the first positioning groove 311, and the second positioning protrusion 120 interacts with the second positioning groove 312; an elastic member 220 is provided in the lower cavity 320, and the elastic member 220 can provide pulling force for the mounting rod 200, so that the mounting platform 100 can be rotated relative to the fixing seat 300 when it rotates, and can be maintained in this position after rotating to a predetermined position. It is understood that the first positioning protrusion 110 and the second positioning protrusion 120 respectively cooperate with the first positioning groove 311 and the second positioning groove 312. The tension provided by the elastic member 220 can ensure that the mounting platform 100 can be accurately stuck in a specific position during the rotation process, achieving a predetermined angle fixation. The cooperation between the first positioning protrusion 110 and the first positioning groove 311 provides low rotational resistance, allowing the mounting platform 100 to rotate freely within a certain angle range, while the cooperation between the second positioning protrusion 120 and the second positioning groove 312 provides additional angular restrictions, effectively limiting the rotation angle of the mounting platform 100 and avoiding instability caused by excessive rotation. In addition, the elastic member 220 is located in the lower cavity 320 and can provide uniform and continuous tension to ensure the locking function between the mounting platform 100 and the fixing base 300. This elastic member 220 effectively enhances stability during rotation and maintains the desired fixed state after the rotation reaches the predetermined angle.

[0030] Furthermore, the height of the first positioning protrusion 110 is lower than that of the second positioning protrusion 120. During the rotation of the mounting platform 100 relative to the fixing base 300, the first positioning protrusion 110 smoothly enters from one first positioning groove 311 to the next, while the second positioning protrusion 120 further restricts the rotation. This ensures the accuracy of the rotation angle and enhances the locking effect of the device.

[0031] In some embodiments, reference Figure 5There are four first positioning protrusions 110, symmetrically distributed along two intersecting vertical lines. There are two second positioning protrusions 120, arranged opposite each other, with the line containing the two second positioning protrusions 120 forming a 45° angle with the two intersecting vertical lines. It can be understood that the symmetrical distribution of the four first positioning protrusions 110 allows the mounting platform 100 to interact evenly with the first positioning groove 311 during rotation, thereby ensuring rotational stability and preventing misalignment. The arrangement of these four positioning protrusions along two intersecting vertical lines increases the precision and stability of the locking point rotation. This effectively distributes the forces during rotation, ensuring more balanced rotation of the mounting platform 100 and preventing mechanical friction or damage caused by misalignment. The number and relative arrangement of the two second positioning protrusions 120 ensure that the second positioning protrusions 120 precisely engage the second positioning groove 312 during rotation, allowing the second positioning protrusion 120 to move within the second positioning groove 312 and be retained in position by the second positioning groove 312.

[0032] Further, refer to Figure 3 、 5 The second positioning groove 312 is symmetrically arranged along the line connecting the first positioning grooves 311 arranged opposite to each other, and the arc of the second positioning groove 312 is 90°. It can be understood that when the first positioning protrusion 110 is engaged with the first positioning groove 311, the second positioning protrusion 120 is located in the second positioning groove 312. Since the arc of the second positioning groove 312 is 90°, the second positioning protrusion 120 will abut against one end of the second positioning groove 312, and the mounting platform 100 will stop rotating relative to the fixed base 300. However, at this time, the mounting platform 100 can be rotated 90° in the other direction along the fixed base 300, and then the first positioning protrusion 110 can be engaged with the first positioning groove 311, and the second positioning protrusion 120 can be engaged with the second positioning groove 312 to achieve positioning and locking. In this way, the rotating shaft frame of the present invention can achieve 90° rotation to the left and right, switching between 0° and 90°.

[0033] In some embodiments, reference Figure 1 、 4 The mounting platform 100 is provided with a connection portion 130 on a side away from the mounting rod 200. It is understood that one end of the fixing base 300 of the rotating shaft stand of the present invention can be connected to a tripod or other bracket, and the connection portion 130 provided on the mounting platform 100 of the rotating shaft stand can be used to connect electronic devices, including but not limited to mobile phones and cameras.

[0034] Further, refer to Figure 4The connecting portion 130 includes opposing connecting arms 131 with mounting holes 132 at their tops. These holes 132 allow for the connection of additional connecting rods, which in turn connect to electronic devices. The connecting rods can rotate relative to the connecting arms 131, enabling not only horizontal rotation but also vertical adjustment at multiple angles. This expands the scope of use and enhances practicality.

[0035] In some embodiments, reference Figure 1 The mounting rod 200 is provided with a latch 210 at its end. One end of the elastic member 220 abuts the partition 330, and the other end abuts the latch 210. It is understood that the latch 210 connects the elastic member 220 to the structure between the mounting rod 200 and the fixing base 300. The latch 210, through the tension of the elastic member 220, ensures that the mounting platform 100 is stably locked in a predetermined position during rotation and secures it in that position, preventing accidental loosening due to external forces or vibration. The tension provided by the elastic member 220 and the close contact of the latch 210 work together to ensure a more reliable rotation of the pivot bracket. The latch 210 is preferably a "C"-shaped latch, with a corresponding mounting opening provided on the mounting rod 200. The elastic member 220 is preferably a spring, which can be mounted on the mounting rod 200 and then secured to the mounting rod 200 via the "C"-shaped latch.

[0036] Further, refer to Figure 1 A first gasket 230 is also provided between the elastic member 220 and the partition 330, and a second gasket 240 is provided between the elastic member 220 and the latch 210. The first gasket 230 is located between the elastic member 220 and the partition 330, effectively reducing direct friction between the elastic member 220 and the partition 330, avoiding wear and premature damage caused by friction, and extending the service life of the elastic member 220 and the partition 330. The second gasket 240 is used to reduce wear when the elastic member 220 contacts the latch 210, avoiding excessive friction caused by direct contact between metal parts, thereby maintaining smoothness and stability during rotation. The second gasket 240 not only helps reduce noise caused by friction, but also alleviates aging or damage to the elastic member 220 and the latch 210 caused by frequent rotation.

[0037] Further, refer to Figure 1The first gasket 230 is provided with an oil reservoir 231 on the side facing the partition 330. The oil reservoir 231 reduces friction between the elastic member 220 and the partition 330 by providing lubrication, thereby improving the smooth rotation and service life of the device. This structure can be a tiny groove, hole, or other oil-retention design that can store and release lubricating oil during rotation, effectively reducing friction between the first gasket 230 and the partition 330.
