[0038] 2, refer to Figures 1-4 In some embodiments, hydraulic control handle 400 includes seat body 410, first plunger 420, liquid guide pipe 430 and trigger 440;Seat body 410 is installed on any telescopic leg 200, and a liquid storage cavity 411 and a liquid outlet 412 communicating with the liquid storage cavity 411 are arranged in the seat body 410, and hydraulic medium is filled in the liquid storage cavity 411;First plunger 420 is arranged in the liquid storage cavity 411;One end of liquid guide pipe 430 communicates with liquid outlet 412, and the other end communicates with hydraulic locking assembly 300;Trigger 440 is rotationally connected to seat body 410 and has a first position and a second position that can be switched with each other;When trigger 440 is switched from the first position to the second position, first plunger 420 is pushed and slides in the liquid storage cavity 411, so that the hydraulic medium is extruded into liquid guide pipe 430 through liquid outlet 412;Or when trigger 440 is switched from the second position to the first position, the force acting on first plunger 420 is removed, so that the hydraulic medium flows back to the liquid storage cavity 411 through the liquid outlet 412.

[0039] With the hydraulic control handle 400 controlling the hydraulic locking assembly 300 to be unlocked as an example, specifically, in the initial state, the trigger 440 is away from the telescopic leg 200 and is in the first position, when the trigger 440 is switched from the first position to the second position (i.e. the trigger 440 moves towards the telescopic leg 200), the trigger 440 will push the first plunger 420 to slide in the liquid storage cavity 411, and then extrude the hydraulic medium in the liquid storage cavity 411 to overflow through the liquid outlet 412 and enter the liquid guide pipe 430, and then along the liquid guide pipe 430 to perform hydraulic unlocking on the hydraulic locking assembly 300; when the telescopic leg 200 is unfolded to the position, the trigger 440 is released, the first plunger 420 loses external power and resets under the pressure of the hydraulic medium, of course, in order to ensure the stability of the reset of the first plunger 420, the fifth elastic member 450 can be arranged in the liquid storage cavity 411 to provide the reset power, at this time, the trigger 440 is switched from the second position to the first position again.

[0040] 3. With reference to Figures 1-4 In some embodiments, the trigger 440 is connected with the seat body 410 through the clutch structure 500, so that the trigger 440 has an operating state and a folding state, the trigger 440 can be switched between the first position and the second position when in the operating state, and the trigger 440 is close to or abuts against the telescopic leg 200 when in the folding state; as a preferred embodiment of the clutch structure 500, the clutch structure 500 includes a clutch block 510, a top block 520, a first elastic member 530 and a second elastic member 540; the clutch block 510 is movably arranged on the trigger 440 and has a third position and a fourth position, and the clutch block 510 is provided with an empty slot 511; the top block 520 is movably arranged on the trigger 440 and abuts against the first plunger 420; the first elastic member 530 abuts against the clutch block 510 and the trigger 440 respectively, and is used for driving the clutch block 510 to switch from the fourth position to the third position; the second elastic member 540 abuts against the top block 520 and the trigger 440 respectively, and is used for driving the top block 520 to reset; the top block 520 can abut against the outer wall of the clutch block 510 when the clutch block 510 is in the third position, so that the trigger 440 enters the operating state; or the top block 520 can extend into the empty slot 511 when the clutch block 510 is in the fourth position, so that the trigger 440 enters the folding state.

[0041] Specifically, taking the example of switching the trigger 440 from the operating state to the folding state, when the trigger 440 is in the operating state, the clutch block 510 is in the third position, and the top block 520 abuts against the outer wall of the clutch block 510 at this time. When the trigger 440 is pressed, the clutch block 510 will be driven to drive the top block 520 to move towards the first plunger 420, thereby causing the hydraulic medium in the liquid storage cavity 411 to overflow through the liquid outlet 412 and enter the liquid guide pipe 430, and then follow the liquid guide pipe 430 to hydraulically unlock the hydraulic locking assembly 300; when it is needed to fold the photographic support, the clutch block 510 is first pressed to switch from the third position to the fourth position, so that the top block 520 will enter the empty slot 511 on the clutch block 510, and then the trigger 440 is pressed again, which will increase the depth of the top block 520 extending into the empty slot 511, and the second elastic member 540 is compressed until the trigger 440 is close to or attached to the telescopic foot 200 Figure 4 , thereby reducing the angle of the trigger 440 opening outward, i.e., further reducing the space occupied by the photographic support when it is folded; it should be noted that the intervention of external force is needed to overcome the friction between the parts and the elastic force of the second elastic member 540 when the trigger 440 enters the folding state, and the second elastic member 540 can drive the top block 520 to reset when the trigger 440 enters the operating state, i.e., drive the top block 520 to disengage from the empty slot 511, so that the clutch block 510 can enter the third position from the fourth position under the drive of the first elastic member 530.

[0042] 4. Refer to Figures 1-4 In some embodiments, the integrated telescopic support foot further comprises a power assisting structure 600 connected between the seat body 410 and the trigger 440.

The power assisting structure 600 not only provides power when the trigger 440 is switched from the operating state to the folding state, but also enables the trigger 440 to remain in the folding state to avoid the trigger 440 from returning to the operating state.

[0043] 5. Refer to Figures 1-4 In some embodiments, the top block 520 is provided with a waist-shaped slot 521 extending in the direction of the elastic force of the second elastic member 540, and the trigger 440 is provided with a limiting portion 522 extending into the waist-shaped slot 521. The limiting portion 522 and the waist-shaped slot 521 cooperate to limit the movement of the top block 520, which can prevent the top block 520 from disengaging from the slot on the trigger 440 and also limit the movement stroke of the top block 520.

[0044] 6. Refer to Figures 1-4 In some embodiments, the seat body 410 is provided with a pressure relief cavity 720 in communication with the liquid storage cavity 411 through a pressure relief hole 710, and further comprises a fourth elastic member 730 arranged in the pressure relief cavity 720 and a second plunger 740, one end of the fourth elastic member 730 abuts against the side of the second plunger 740 away from the pressure relief hole 710, and the other end abuts against the pressure relief cavity 720; because the user may use excessive force when operating the trigger 440, thereby causing excessive pressure on the components and causing damage to the components, the arrangement can allow the hydraulic medium to enter the pressure relief cavity 720 through the pressure relief hole 710 when the pressure is too large, and be absorbed by the fourth elastic member 730, thereby avoiding excessive pressure in the liquid storage cavity 411 and the liquid guide pipe 430.
