In another embodiment, based on the above embodiments, as shown in fig. 1, 2 and 5, the stopper further includes a lever 145 engaged with the link 143, specifically, the lever 145 is slidably connected to the second housing 102 and at least partially located outside the second housing 102, which is convenient for a user to operate, a side wall of the link 143 is provided with a chute 1430 engaged with the lever 145, two ends of the chute 1430 are respectively provided with a first stopper slot 1431 and a second stopper slot 1432 engaged with the lever 145, the chute 1430 is inclined along a rotation direction of the link 143, when the lever 145 slides to an end of the chute 1430 far away from the boss 142 (i.e., the first stopper slot 1431), the link 143 drives the lock catch 141 to move towards the boss 142 under the action of the stopper elastic member 144, and when the lever 145 slides to an end of the chute 1430 near the boss 142 (i.e., the second stopper slot 1432), the link 143 presses the stopper elastic member 144, the catch 141 moves away from the boss 142.

1431 and 1432 are used to stably lock or unlock the shift lever 145, and in other embodiments, two limit positions may be provided between the shift lever 145 and the handle housing 10 to achieve the above-mentioned effect.

In another embodiment, on the basis of the above embodiments, as shown in fig. 2 and fig. 7, the central shaft 134 is fixedly connected with a coaxial ratchet wheel 133, the hand-held part 1 is provided with a pawl 130 which is matched with a ratchet wheel 133, in particular, the pawl 130 limits the rotation of the ratchet wheel 133 (namely, a middle shaft 134) to the direction of the resilience force of a coil spring 137, therefore, the fixed connection between the central shaft 134 and the hand-held part 1 is realized through the matching of the ratchet wheel 133 and the pawl 130, and in addition, the rotation of the ratchet wheel 133 can be adjusted to drive the coil spring 137 to tighten or loosen, i.e., the position at which the bar 136 is engaged with the rotary wheel 135 at the initial moment, can be adjusted, it is noted that, since the vertical movement includes both upward and downward directions, at the initial moment (i.e. after the load is installed), the rotating wheel 135 can be adjusted to be matched with the position approximately in the middle of the bar-shaped rod 136 through the ratchet wheel 133, and the vertical damping mechanism 13 can better damp the vertical upward and downward directions.

In another embodiment, on the basis of the above embodiments, as shown in fig. 1 and fig. 2, the side wall of the ratchet wheel 133 is provided with a thread protrusion 1331 coaxial therewith; the vertical shock absorbing mechanism 13 further comprises a limit nut 1330 matched with the threaded boss 1331 and a cover plate 1332 fixedly connected with the hand-held part shell 10; the cover plate 1332 is provided with a limit nut guide groove 1333, the outer ring of the limit nut 1330 and the inner ring of the limit nut guide groove 1333 are provided with a limit structure matched with each other, and the limit structure can be specifically matched with a protrusion and a groove, a polygon, an ellipse and other shapes. The limiting structure of the limiting nut 1330 and the limiting nut guide groove 1333 can limit the movement of the limiting nut 1330 in the guide groove along the axial direction thereof without rotating; since the ratchet wheel 133 drives the threaded protrusion 1331 to rotate and simultaneously drives the limit nut 1330 to move along the axial direction of the limit nut guide slot 1333 during the adjustment process, the limit nut 1330 can move to the threaded end of the threaded protrusion 1331 in the first direction and to the end of the limit nut guide slot 1333 (i.e., the inner wall of the cover plate 1332) in the second direction, the embodiment can determine the two positions according to the specific stroke of the coil spring 137, thereby protecting the coil spring 137 during the adjustment process.

In another embodiment, on the basis of the above embodiment, the vertical damping mechanism further includes a position sensor for measuring a vertical position of a first end of the vertical damping mechanism, a controller and a motor, wherein the controller receives a vertical position signal from the position sensor and generates an output signal for controlling the motor to operate, the motor includes a rotating end provided with a motor shaft and a fixed end carrying a motor core, the rotating end is coaxially and fixedly connected with the rotating wheel, and the fixed end is fixedly connected with the handheld portion housing; the position sensor is specifically a sensor with an Inertial Measurement Unit (IMU) and is used for measuring the vertical position of the first end 131 (load) of the vertical damping mechanism, the controller receives a vertical position signal from the position sensor and generates an output signal for controlling the action of the motor, and specifically, the position sensor is fixedly installed at the first end 131 of the vertical damping mechanism, and the controller is installed inside the motor and is in communication connection with the motor; the motor comprises a rotating end provided with a motor shaft and a fixed end carrying a motor iron core, the rotating end is fixedly connected with a rotating wheel 135, specifically, the rotating wheel 135 is coaxially and fixedly connected with the motor shaft, and the fixed end is fixedly connected with the handheld part shell 10; in this embodiment, the torque of the motor drives the rotating wheel 135 and the bar rod 136 to move relatively, so that the first end 131 of the vertical damping mechanism moves along the direction opposite to the vibration direction, and thus the first end 131 of the vertical damping mechanism is positioned at the determined position in the vertical direction, which can further accurately control the first end 131 of the vertical damping mechanism to be always positioned at the determined position in the vertical direction.

Specifically, when the first end 131 of the vertical damping mechanism vibrates vertically (for example, due to slight fluctuation caused by the user's step), the position sensor acquires the actual vertical position of the load and then transmits a signal of the actual vertical position to the controller, the position sensor can acquire the actual vertical position of the load in real time or periodically and transmit the actual vertical position to the controller, the controller has preset vertical position information therein and judges whether the actual vertical position is deviated (different) from the preset vertical position based on the received signal of the actual vertical position; when the actual vertical position is higher than the preset vertical position, that is, it means that the first end 131 of the vertical shock-absorbing mechanism has a rapid downward falling motion, at this time, the position controller drives the rotating wheel 135 to rotate upward along the bar-shaped rod 136 through the rotation of the driving motor, so that the bar-shaped rod 136 moves downward relative to the handheld portion housing 10, thereby offsetting the shake of the first end 131 of the vertical shock-absorbing mechanism in the vertical direction and positioning the load at a certain position in the vertical direction; similarly, when the actual vertical position of the first end 131 of the vertical shock absorbing mechanism is lower than the preset vertical position, that is, it means that the first end 131 of the vertical shock absorbing mechanism has a rapid downward falling motion, at this time, the position controller drives the rotating wheel 135 to rotate downward along the bar-shaped rod 136 through the rotation of the driving motor, so that the bar-shaped rod 136 moves upward relative to the handheld portion housing 10, which can also counteract the shaking of the first end 131 of the vertical shock absorbing mechanism in the vertical direction and position the load at the determined position in the vertical direction. The mode of motor active damping and coil spring passive damping is adopted in the embodiment, and compared with the mode of singly adopting passive stability augmentation, the mode of actively augmenting stability by utilizing the position sensor, the controller and the motor has shorter response time, and can carry out accurate displacement compensation.

In another embodiment, on the basis of the above embodiments, as shown in fig. 2 and 5, the stopper further includes a boat switch 146 cooperating with the controller, and the controller receives the first direction signal and the second direction signal of the boat switch 146 and respectively generates a control signal for controlling the motor to drive the rotating wheel 135 to rotate upward along the bar-shaped bar 136 and to drive the rotating wheel 135 to rotate downward along the bar-shaped bar 136. Particularly, the bar-shaped rod 136 is automatically recovered and the vertical damping mechanism is locked by driving a motor to rotate through a ship-shaped switch 146; when the controller receives a first direction signal of the ship-shaped switch 146, the generated control motor drives the rotating wheel 135 to rotate upwards along the bar-shaped rod 136, namely, the bar-shaped rod 136 is recovered into the cavity 103, and when the boss 142 is matched with the lock catch 141, automatic locking is realized under the action of the stop elastic piece 144; when the controller receives a second direction signal of the ship-shaped switch 146, the generated control motor drives the rotating wheel 135 to rotate downwards along the bar-shaped rod 136, at this time, the operating lock catch 141 is separated from the boss 142, and the bar-shaped rod 136 moves upwards relative to the handheld portion 1, so that unlocking is realized. In addition, when vertical damper carries on the triaxial cloud platform, this embodiment can realize automatic switch-over triaxial mode and four-axis mode.

In another embodiment, as shown in fig. 2 and 5, the shift lever 145 not only can be engaged with the connecting rod 143 to unlock and lock the bar 136, but also the shift lever 145 can trigger the first direction signal and the second direction signal of the ship switch 146 in the above two states to engage with the ship switch. In the using process, when the shifting lever 145 is located in the first direction signal, the motor drives the rotating wheel 135 to rotate upwards along the bar-shaped rod 136, the lock catch 141 is subjected to the elastic force of the stopping elastic piece 144, the bar-shaped rod 136 moves to the position where the boss 142 is matched with the lock catch 141, the lock catch 141 is automatically matched with the boss 142, when the shifting lever 145 is located in the second direction signal, the shifting lever 145 drives the lock catch 141 to move towards the opposite direction of the elastic force of the stopping elastic piece 144, namely, the shifting lever 142 is separated, and the bar-shaped rod 136 moves upwards relative to the handheld portion 1, so that automatic unlocking is achieved.

In a further embodiment, a second silica gel layer 32 is disposed between the quick release seat 15 and the first end 131 of the vertical shock absorbing mechanism (top end of the bar-shaped rod 136), so as to isolate the load of the first end 131 of the vertical shock absorbing mechanism from the handheld portion 1, thereby reducing the influence of the vibration of the vertical shock absorbing mechanism 13 on the load, and further improving the shooting stability. In other embodiments, the first silica gel layer 31 may be further added at the bottom of the quick release base 15, or both of the two places may be provided with silica gel layers.
