When the camera 42 needs to be erected by using the invention, the lock mechanisms a10 at all the hinged parts between the round rod D6 and the round rod C5 in the rod mechanism A1 and the hinged part between the rod mechanism A1 and the cylinder a47 are firstly opened, the lock mechanism B11 which is matched with the cylinder a47 and the rotary column 4 on the ring sleeve 9 in a rotating mode is opened, and the lock structure between the round rod E16 and the round rod F17 in the rod mechanism B15 is opened.

The procedure for opening the lock mechanism a10 is as follows:

turning the bolt 13 in the lock mechanism a10 causes the bolt 13 to disengage from the locking slot 8 in the respective hinge pin 7, and completing the opening of the lock mechanism a10 when the bolt 13 disengages from the locking slot 8.

The procedure for opening the lock mechanism a10 is as follows:

the bolt 13 in the lock mechanism B11 is rotated so that the bolt 13 is disengaged from the locking groove 8 on the corresponding rotary column 4, and the opening of the lock mechanism B11 is completed when the bolt 13 is disengaged from the locking groove 8.

The procedure for opening the lock between the round bar E16 and the round bar F17 is as follows:

and (3) rotating the threaded sleeve 20, wherein the threaded sleeve 20 drives the round rod G21 to move towards the tail end of the round rod F17, the conical tip at the tail end of the round rod G21 releases the pressing on the two locking blocks 19, and the pressing between the two locking blocks 19 and the inner wall of the round rod E16 is released, so that the opening of the locking structure between the round rod E16 and the round rod F17 is completed.

After the lock mechanisms a10 and B11 in the rod mechanism A1, the lock mechanism a10 between the rod mechanism A1 and the cylinder a47, the lock mechanism B11 between the cylinder a47 and the rotary column 4 on the ring sleeve 9, and the lock mechanism between the round rod E16 and the round rod F17 in the rod mechanism B15 are opened, the round rod C5 and the round rod D6 in each rod mechanism A1 are completely opened with respect to the corresponding round rod B3 so that the rod mechanism A1 is completely unfolded to the linear state. After the two lever mechanisms A1 are completely deployed, the lock mechanisms a10 that are opened in each lever mechanism A1 are respectively locked again.

The flow of the locking mechanism a10 is as follows:

the bolts 13 in the lock mechanism a10 are turned so that the bolts 13 are reinserted into the corresponding locking grooves 8 in the corresponding hinge pins 7, and the relocking of the lock mechanism a10 is completed when the bolts 13 are inserted into the locking grooves 8.

Then, the round bar F17 in the bar mechanism B15 is extended to a desired length with respect to the round bar E16 and the round bar E16 is locked again with the round bar F17 by turning the screw sleeve 20 and bringing the two locking pieces 19 by the round bar G21.

Then, the relative divergence angle between the two lever mechanisms A1 and the divergence angle of the lever mechanism B15 with respect to the two lever mechanisms A1 are adjusted according to the height to which the camera 42 is to be erected. After the relative positions of the two rod mechanisms A1 and B15 are adjusted, the lock mechanism A10 at the hinged position between the rod mechanism A1 and the cylinder A47 and the lock mechanism B11 at the rotating position between the cylinder A47 and the upper rotary column 4 on the ring sleeve 9 are locked, so that the relative positions of the two rod mechanisms A1 and B15 are fixed.

Then, the lock mechanism a10 between the round bar E16 and the lower end cylinder C29 of the platform mechanism 22 in the bar mechanism B15 is opened, and after swinging the pedestal 23 to the horizontal state, the lock mechanism a10 between the round bar E16 and the lower end cylinder C29 of the platform mechanism 22 is locked again to fix the horizontal position of the pedestal 23.

When the trapezoidal socket 43 of the camera 42 passes over the driving inclined plane a31 on the inverted trapezoidal bar 30 and then starts to interact with the driving inclined plane B36 on the stopper 35, the stopper 35 moves vertically downward along the sliding slot D26 under the action of the trapezoidal socket 43 of the camera 42 and the driving inclined plane a31, and the spring B37 is further compressed. The limiting block 35 drives the fixture block B40 on the sliding sleeve 39 to insert into the gap between the fixture blocks a46 on the corresponding racks 32 and lock the positions of the racks 32 to a certain extent, so as to lock the relative positions of the two inverted trapezoidal strips 30 to a certain extent.

When the trapezoidal socket 43 of the camera 42 is completely inserted between the two inverted trapezoidal strips 30 and meets the limiting strip 24 at one end of the pedestal 23, the trapezoidal socket 43 of the camera 42 is just separated from the limiting block 35, the limiting block 35 instantly pops up by a small extent under the reset action of the spring B37, and the pressing plate 50 on the limiting block 35 abuts against the trapezoidal socket 43 of the camera 42, so that the fixture block B40 on the sliding sleeve 39 at the lower end of the limiting block 35 is still located in the gap between the fixture blocks a46 and keeps locking the two inverted trapezoidal strips 30.

The upward spring of the limiting block 35 limits the trapezoidal socket 43 of the camera 42 between the two inverted trapezoidal strips 30 and the limiting strip 24, so that the position of the camera 42 on the pedestal 23 is fixed, and the camera 42 is prevented from being thrown out of the pedestal 23 due to violent sliding.

When two rod mechanisms A1 which are matched with the rod mechanism B15 to support the camera 42 in a three-legged manner are impacted, the hinge pins 7 at all the hinged positions rotate to a small extent, the sliding blocks 12 of all the lock mechanisms A10 slide to a small extent under the action of the corresponding hinge pins 7, and the two plate springs 14 deform correspondingly, so that the impact on the hinged positions is effectively buffered, and the impact damage on all the hinged positions below the platform mechanism 22 in the invention is weakened.

When two rod mechanisms A1 which are matched with the rod mechanism B15 to support the camera 42 in a three-legged manner are impacted, the rotary columns 4 at all rotation matching positions can rotate in a small range, the sliding blocks 12 of all lock mechanisms B11 can slide in a small range under the action of the corresponding rotary columns 4, and the two plate springs 14 deform correspondingly, so that impact on the rotation matching positions is effectively buffered, and impact damage on all rotation matching positions below the platform mechanism 22 is weakened.

After the impact, the sliding blocks 12 in the lock mechanisms A10 and B11 are respectively reset instantly under the reset action of the corresponding two plate springs 14, and the sliding blocks 12 drive the structures fixedly connected with the hinge pins 7 or the rotary columns 4 to swing back and reset through the bolts 13.

When the invention is needed to be used for taking a picture in motion, the unlocking ring sleeve 9 is used for rotating the lock mechanism B11 between the column 4 and the cylinder A47, rotating the lock mechanism A10 between the cylinder A47 and the round rod A2 in the rod mechanism A1, and rotating all the lock mechanisms A10 and all the lock mechanisms B11 except the round rods D6 and C5 in the rod mechanism A1.

The round bar C5 in each bar mechanism A1 is bent and locked to a certain extent relative to the round bar B3, then the two bar mechanisms A1 are swung to a certain extent relative to the ring sleeve 9 and rotated to a certain extent relative to the ring sleeve 9 to be locked, then the round bar B3 in the bar mechanism A1 is rotated to a certain extent relative to the round bar A2 to be locked, finally the round bar C5 and the round bar D6 in the two bar mechanisms A1 are just clamped and fixed on two sides of the waist of a person, the bar mechanism B15 is arranged on the shoulder, then the lock mechanism A10 between the unlocking cylinder C29 and the round bar E16 adjusts the pedestal 23 to be horizontal and then is locked, and therefore the erection of the two bar mechanisms A1 and the bar mechanism B15 on the person is completed, and the stable photographing in the movement is facilitated.

When the ground unevenness that rod mechanism A1 and rod mechanism B15 located, through two rod mechanism A1 round bar C5 of unblock and round bar B3 and round bar C5 and round bar D6 between the lock mechanism A10 with round bar C5 for round bar B3 upper hem and with round bar D6 for round bar C5 lower hem in every rod mechanism A1, through making the terminal shrink of round bar D6 realize the effective shrink of short rod mechanism A1 length in every rod mechanism A1 to adaptation unevenness ground.

The telescopic length of the rod mechanism B15 is then adjusted to achieve stable support of the present invention on uneven ground while maintaining the height of the pedestal 23.

In conclusion, the beneficial effects of the invention are as follows: the tripod support device realizes triangular support through the two rod mechanisms A1 and the one rod mechanism B15, the two rod mechanisms A1 serving as main supports realize the height adjustment of the tripod by adopting the combination of a rotating structure and a hinging structure with higher strength, and the two rod mechanisms A1 can achieve the effect of stabilizing the camera 42 during running in a mode of rotating, bending, clamping and fixing the two rod mechanisms A1 on the waist of a photographer when the photographer needs to take a picture during running.

The rod mechanism B15 which is used as an auxiliary support and adopts a telescopic structure can drive the camera 42 on the platform mechanism 22 to carry out larger-amplitude pushing or zooming operation towards the scenery when the scenery needs to be pushed or zoomed out.
