In one embodiment, referring to fig. 3 and 4, the handset clip assembly 30 includes: the mobile phone holder comprises a support arm 31 and a mobile phone holder body 32, wherein the support arm 31 extends along a first direction (i.e. the vertical direction in fig. 1), the support arm 31 comprises a fixing piece 33 and a telescopic piece 34 which extend along the first direction, an accommodating space 331 is formed in the fixing piece 33, the telescopic piece 34 is telescopically arranged in the accommodating space 331, one end of the telescopic piece 34 extends outwards from the accommodating space 331 and is connected to the mobile phone holder body 32, and a locking mechanism is arranged between the telescopic piece 34 and the fixing piece 33 and used for limiting the telescopic piece 34 to slide relative to the fixing piece 33 when the telescopic piece 34 stretches out. The handset grip body 32 is provided with an elastic grip space 321 for gripping the handset, and is rotatably provided at the front side of the support arm 31.

In the non-use state, the telescopic member 34 is retracted in the accommodation space 331 of the fixed member 33, and the locking structure is in the non-locking state; when the mobile phone clamp is used, the mobile phone clamp main body 32 is pulled upwards, the telescopic piece 34 drives the mobile phone clamp main body 32 to slide upwards relative to the fixing piece 33 until the locking structure is in a locking state, so that the telescopic piece 34 is fixed relative to the fixing piece 33, and then the mobile phone is clamped in the elastic clamping space 321. Through the telescopic structure of the mobile phone clamp assembly, the axial length of the mobile phone clamp assembly is reduced when the mobile phone clamp assembly is not in use, the mobile phone clamp assembly is convenient to store, and for the foldable photographic support, as the length of the mobile phone clamp assembly is shortened, under the condition that the length of the foldable photographic support is fixed, the contraction length of the telescopic rod assembly 20 (namely the length of the telescopic rod assembly 20 when all pipes are in contraction) is prolonged, the same extension length is met, fewer pipes are needed, and the product cost is low.

Referring to fig. 5-9, in one embodiment, the locking mechanism includes a positioning recess 332 provided on a wall of the accommodating space 331 and a resiliently retractable positioning protrusion 351 provided on the telescopic member 34 and cooperating with the positioning recess 332, and when the telescopic member 34 is extended, the positioning protrusion 351 is caught in the positioning recess 332.

The elastic member 36 keeps providing an outward pushing force to the positioning member 35, and when the expansion member 34 is extended, the positioning convex portion 351 is quickly snapped into the positioning concave portion 332 to complete the locking action; when the expansion member 34 is retracted into the fixing member 33, the urging force of the elastic member 36 makes the positioning protrusion 351 abut against the inner wall of the accommodating space 331 to generate a larger friction force, so that the expansion member 34 is not easily slid out of the accommodating space 331.

Referring to fig. 9 and fig. 18 to fig. 20, in one embodiment, the outer surface of the positioning protrusion 351 has an arc-shaped compression area P1, and the inner wall of the positioning recess 332 has a compression area P2, when the expansion member 34 is in the extended state and the pressure applied between the expansion member 34 and the fixing member 33 exceeds a preset bearing (the preset bearing is designed according to the actual requirement and should be greater than the weight of the electronic device), the compression area P2 will press the compression area P1, so that the positioning protrusion 351 is retracted. The advantage of this design is that when the user wishes to perform the folding operation, the user only needs to press down on the telescopic member by hand, and once the applied force reaches a certain standard, the positioning convex portion will retract and separate from the positioning concave portion 332, so that the telescopic member 34 slides into the preset accommodating space 331. The structure not only allows the user to directly press the positioning convex part to realize folding, but also can be completed by applying pressure to the telescopic piece, thereby greatly improving the use convenience. At the same time, the design also reduces the damage risk possibly suffered by the positioning convex part and the positioning concave part under the action of excessive force.

In one embodiment, the outer surface of the positioning protrusion 351 includes an arc surface 3511 with an outer diameter gradually increasing from the top to the root, the compression area is located on the arc surface 3511, the inner wall of the positioning recess 332 near one end of the expansion element 34 is a circumferential surface (or is an arc surface matched with the outer surface of the positioning protrusion 351), and the compression area P2 is located on the inner wall of the positioning recess 332 near one end of the expansion element 34. When the folding operation is performed, the mobile phone holder main body 32 or the telescopic member 34 is pressed, and the inner hole of the positioning concave portion 332 presses the surface of the positioning convex portion 351, so that the positioning member 35 is retracted toward the inside of the telescopic member 34 against the elastic force of the elastic member 36, thereby the folding operation is performed without pressing the positioning member 35 alone, and the convenience of use is improved.

In one embodiment, the bottom of the mounting groove 341 is provided with a mounting sleeve 342 protruding toward the positioning member 35, the positioning member 35 is provided with a groove 352 opposite to the mounting sleeve 342, the mounting sleeve 342 extends into the groove 352, the elastic member 36 is a spring, and the elastic member 36 is mounted in the mounting sleeve 342. The placement of the two ends of the resilient member 36 within the mounting sleeve 342 and the recess 352, respectively, stabilizes the positioning of the resilient member 36 and thereby provides a more stable resilient force.
