The first driving member, the second driving member and the third driving member are respectively used to drive the first clamping member  300 , the second clamping member  310  and the touch member  320  to move. The three driving members can drive the first clamping member  300 , the second clamping member  310  and the touch-control member  320  respectively by various means such as an elastic force or a magnetic force. In an embodiment, the three driving members drive the first clamping member  300 , the second clamping member  310  and the touch member  320  to move by an elastic force. That is, the first driving member is a first elastic member  400 , the second driving member is a second elastic member  410 , and the third driving member is a third elastic member  420 . The first elastic member  400  and the second elastic member  410  are arranged in the first sliding groove  100 . Two ends of the first elastic member  400  are respectively connected to the limit seat  110  and the press seat  303  of the first clamping member  300 . Two ends of the second elastic member  410  are respectively connected to the limit seat  110  and the press seat  303  of the second clamping member  310 . An end of the touch body  3201  facing the limit seat  110  is provided with an accommodating cavity, and the third elastic member  420  is provided in the accommodating cavity. Two ends of the third elastic member  420  are respectively connected to a bottom surface of the mounting groove  111  and a bottom surface of the accommodating cavity. 
     As shown in  FIGS. 8, 9 and 11 , the quick-assembly seat  6  has a clamped state and an unclamped state. In the clamped state, the quick-assembly seat  6  and the quick-release part  2  are clamped together. The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  are far away from each other. The clamping grooves  3013  of the first clamping member  300  and the second clamping member  310  are separated from the two clamping pieces  3202  of the touch member  320  respectively. The third elastic member  420  elastically presses the touch body  3201  to drive the two clamping pieces  3202  to respectively abut against the first surface  3011  of the first clamping member  300  and the first surface  3011  of the second clamping member  310 . 
     As shown in  FIGS. 4, 7, 9, and 11 , in the unclamped state, the quick-assembly seat  6  is separated from the quick-release part  2 . The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  approach each other. The clamping grooves  3013  of the first clamping member  300  and the second clamping member  310  are respectively clamped with the two clamping pieces  3202  of the touch member  320 . The first elastic member  400  and the second elastic member  410  accumulate an elastic force. Two ends of the first elastic member  400  press against the limit seat  110  and the press seat  303  of the first clamping member  300  respectively. Two ends of the second elastic member  410  press against the limit seat  110  and the press seat  303  of the second clamping member  310  respectively. 
     As shown in  FIGS. 4, 6, 7, 9 and 11 , when the quick-release part  2  needs to be connected, the press seat  303  of the first clamping member  300  and the press seat  303  of the second clamping member  310  are oppositely squeezed to drive the first clamping member  300  and the second clamping member  310  to move toward each other. The clamping groove  3013  of the first clamping member  300  and the clamping groove  3013  of the second clamping member  310  are respectively clamped with the two clamping pieces  3202  of the touch member  320 . The first elastic member  400  and the second elastic member  410  accumulate an elastic force. The quick-release part  2  moves along the second direction, and the quick-release part  2  may move toward or away from the first sliding groove  100 . When the quick-release part  2  moves toward the first sliding groove  100 , positions of the first clamping member  300  and the second clamping member  310  to be clamped with the touch member  320  face the first sliding groove  100 . The third elastic member  420  is compressed to accumulate an elastic force. When the quick-release part  2  moves away from the first sliding groove  100 , the positions of the first clamping member  300  and the second clamping member  310  to be clamped with the touch member  320  face away from the first sliding groove  100 . The third elastic member  420  is stretched to accumulate an elastic force. In an embodiment, the quick-release part  2  moves toward the first sliding groove  100 . That is, the quick-release part  2  presses against the touch member  320  toward the first sliding groove  100 , and drives the touch member  320  to move close to the first sliding groove  100  in the second direction until the clamping groove  3013  of the first clamping member  300  and the clamping groove  3013  of the second clamping member  310  are separated from the two clamping pieces  3202  of the touch member  320  respectively. The first elastic member  400  and the second elastic member  410  release the elastic force to drive the first clamping member  300  and the second clamping member  310  to move away from each other. The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  are respectively clamped into clamping slots  24  of the quick-release part  2 . The third elastic member  420  is compressed to accumulate an elastic force. 
     As shown in  FIGS. 4 and 5 , in another embodiment, the driving assembly  40  may also drive the first clamping member  300 , the second clamping member  310  and the touch member  320  to move by a magnetic force. In other words, the first elastic member  400 , the second elastic member  410 , and the third elastic member  420  in the above embodiment are each replaced with two magnets  430 . That is, there are three sets of magnets  430 , with two magnets  430  in each set. The two magnets  430  of the first set are respectively provided on the limit seat  110  and a side of the press seat  303  of the first clamping member  300  facing the limit seat  110 . The two magnets  430  of the second set are respectively provided on the limit seat  110  and a side of the press seat  303  of the second clamping member  310  facing the limit seat  110 . The two magnets  430  of the third set are respectively provided at a bottom of the mounting groove and a bottom of the accommodating cavity of the touch member  320 . The two magnets  430  of each set maintain a repulsive state. When the first clamping member  300 , the second clamping member  310  and the touch member  320  move, the corresponding two magnets  430  accumulate and release a magnetic force, so as to achieve the same effect as the corresponding elastic member accumulating and releasing an elastic force. 
     When the quick-release part  2  needs to be disassembled, the press seat  303  of the first clamping member  300  and the press seat  303  of the second clamping member  310  are oppositely squeezed to drive the first clamping member  300  and the second clamping member  310  to move toward each other. The clamping groove  3013  of the first clamping member  300  and the clamping groove  3013  of the second clamping member  310  are respectively clamped with the two clamping pieces  3202  of the touch member  320 . The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  are respectively separated from the clamping slots  24  of the quick-release part  2  such that the quick-release part  2  is unclamped. 
     In another embodiment, the quick-release part  2  may be mounted without pressing the touch member  320 . That is, the quick-release part  2  may directly be moved relative to the quick-assembly seat  6  to be clamped. The first clamping member  300  and the second clamping member  310  need to move for a distance of L1 from the state of being clamped with the quick-release part  2  to the state of being clamped with the touch member  320 . When the quick-release part  2  is not mounted, the touch member  320  may also be pressed to drive the first clamping member  300  and the second clamping member  310  of the quick-assembly seat  6  to move away from each other to achieve a clamped state. At this time, the quick-release part  2  is not mounted on the quick-assembly seat  6 . Then, the quick-release part  2  can also be mounted without pressing to drive the first clamping member  300  and the second clamping member  310  to move toward each other to be clamped with the touch member  320 . Specifically, the quick-release part  2  is directly moved close to the quick-assembly seat  6  along the second direction. The clamping slots  24  of the quick-release part  2  respectively press against the clamping flanges  3022  of the two hooks  302  to drive the first clamping member  300  and the second clamping member  310  to move toward each other. After the two clamping members  2  move for a distance of L2, the clamping slots  24  of the quick-release part  2  correspond to the positions of the two clamping flanges  3022  respectively. The first clamping member  300  and the second clamping member  310  move away from each other under the action of the corresponding elastic members until they are respectively clamped into the clamping slots  24  of the quick-release part  2 . L2 is less than L1, such that when the clamping slots  24  of the quick-release part  2  respectively correspond to the positions of the two clamping flanges  3022 , the first clamping member  300  and the second clamping member  310  are not yet clamped with the touch member  320 . Thus, the first clamping member  300  and the second clamping member  310  can move away from each other to be respectively clamped into the clamping slots  24  of the quick-release part  2 . 
     In another embodiment, the touch member  320  of this embodiment may have a longer length. When the quick-release part  2  moves close to the quick-assembly seat  6 , the quick-release part  2  first presses the touch member  320 , such that the touch member  320  compresses the third elastic member  420 . The two clamping pieces  3202  of the touch member  320  are respectively separated from the clamping groove  3013  of the first clamping member  300  and the clamping groove  3013  of the second clamping member  310 . The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  move away from each other. At this time, the quick-release part  2  is not yet clamped with the two hooks  302 . The quick-release part  2  continues to compress the third elastic member  420 , and edges of the clamping slots  24  of the quick-release part  2  respectively press against the clamping flanges  3022  of the two hooks  302 . In this way, the first clamping member  300  and the second clamping member  310  move toward each other. When the clamping slots  24  of the quick-release part  2  correspond to the positions of the two clamping flanges  3022 , the first clamping member  300  and the second clamping member  310  move away from each other under the action of the corresponding elastic members until they are respectively clamped into the clamping slots  24  of the quick-release part  2 . Compared with the above embodiment, in this embodiment, the touch member  320  is triggered before the quick-release part  2  is clamped with the two hooks  302 , which facilitates the mounting of the quick-release part  2 . 
     As shown in  FIGS. 9, 11 and 12 , the present invention further provides a quick-release assembly, including the quick-release part  2  and the quick-assembly seat  6 . The quick-release part  2  includes a quick-release body  21 . A side of the quick-release body  21  facing the quick-assembly seat  6  is provided with the clamping slots  24 . The clamping slots  24  are respectively clamped with or separated from the hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310 . Specifically, a side of the quick-release body  21  facing the quick-assembly seat  6  is provided with a mounting cavity  23 . A side wall of the mounting cavity  23  is provided with the clamping slots  24  along a circumferential direction, such that the quick-release part  2  can be clamped with the quick-assembly seat  6  in all directions, which is convenient for use. 
     As shown in  FIGS. 4, 9 and 11 , the quick-release body  21  may be made of a magnetic material, such as metal, which is convenient for magnetic connection with the first magnetic member  11  in the seat body  1 , and is convenient for assembly with the quick-assembly seat  6 . Alternatively, the quick-release body  21  may be made of a non-magnetic material, such as plastic. In addition, a second magnetic member  22  is provided on the side of the quick-release body  21  facing the quick-assembly seat  6 . When the quick-release body  21  is close to the quick-assembly seat  6 , the first magnetic member  11  and the second magnetic member  22  approach each other due to magnetic attraction. Thus, the quick-release body  21  presses against the touch body  3201  to move toward the third elastic member  420  in the second direction. When it moves to a certain extent, the two clamping pieces  3202  of the touch member  320  are separated from the clamping groove  3013  of the first clamping member  300  and the clamping groove  3013  of the second clamping member  310  respectively. The first elastic member  400  and the second elastic member  410  respectively release elastic forces to drive the first clamping member  300  and the second clamping member  310  to move away from each other. The hook  302  of the first clamping member  300  and the hook  302  of the second clamping member  310  move away from each other to be clamped into the clamping slots  24  of the quick-release body  21  respectively. In this way, the quick-release part  2  and the quick-assembly seat  6  can be quickly assembled, and after assembly, the quick-release part  2  and the quick-assembly seat  6  are not easily separated, achieving stable connection. 
     As shown in  FIGS. 9, 11 and 13 , the quick-assembly seat  6  further includes a first connection structure connected to the base  10 , and the quick-release part  2  further includes a second connection structure connected to the quick-release body  21 .

The second connection structure is used to connect a mobile phone  4 , and the first connection structure is used to connect a bicycle, such that the mobile phone  4  is connected to the bicycle through the quick-release assembly. 
     As shown in  FIGS. 11 and 12 , in an embodiment, the second connection structure is a mobile phone case  25 . The mobile phone case  25  may be bonded to the side of the quick-release part  2  facing away from the quick-assembly seat  6  by super glue. A side of the mobile phone case  25  facing away from the quick-release part  2  is provided with an limiting groove  251 . The mobile phone case  25  is adapted to the model of the mobile phone  4  such that the mobile phone  4  can be stably mounted in the limiting groove  251  of the mobile phone case  25 . 
     As shown in  FIGS. 9, 10 and 13 , in this embodiment, the first connection structure may be a rotating assembly  3 . The rotating assembly  3  includes a first gripping member  31 , a second gripping member  32 , a rotating seat  33  and a supporting member  34 . One end of the supporting member  34  is connected to the quick-assembly seat  6 . The supporting member  34  and the quick-assembly seat  6  may be detachably connected, or may be fixedly connected by welding or integral molding. In this embodiment, the supporting member  34  and the quick-assembly seat  6  are integrally molded. The other end of the supporting member  34  is rotatably connected to the rotating seat  33  by a first tightening screw  35 . The first tightening screw  35  can adjust the tightness between the supporting member  34  and the rotating seat  33 , thereby adjusting the relative position of the supporting member  34  and the rotating seat  33 . In this way, the supporting member  34  is configured to rotate relative to the rotating seat  33  in a third direction to adjust the position of the mobile phone  4 . An end of the rotating seat  33  away from the supporting member  34  is rotatably connected to the first gripping member  31  by a second tightening screw  36 . The second tightening screw  36  can adjust the tightness between the rotating seat  33  and the first gripping member  31 , thereby adjusting the relative positions of the rotating seat  33  and the first gripping member  31 . In this way, the rotating seat  33  is configured to rotate relative to the first gripping member  31  in a fourth direction to adjust the position of the mobile phone  4 . The third direction may be perpendicular to the fourth direction. Limit slots  38  are respectively provided at opposite parts of the first gripping member  31  and the second gripping member  32 . Two sides of the second gripping member  32  are respectively provided with connecting holes, and two corresponding sides of the first gripping member  31  are respectively provided with threaded mounting holes. During mounting, the limit slots  38  defined by the first gripping member  31  and the second gripping member  32  are buckled on the joystick  5  of the bicycle. Two connecting screws  37  respectively pass through the connecting holes of the second gripping member  32  and are respectively threadedly connected to the threaded mounting holes of the first gripping member  31 , such that the rotating assembly  3  together with the mobile phone  4  is detachably mounted on the bicycle. 
     As shown in  FIGS. 10 and 13 , a rider can adjust and fix the mobile phone  4  at a suitable position when using the mobile phone  4  to take pictures of riding scenery along the way. First, a screwdriver is used to loosen the tightening screw  35  and the second tightening screw  36 . Then the supporting member  34  and the rotating seat  33  are rotated until the quick-assembly seat  6  and the mobile phone  4  are rotated together to a target position. Finally, the screwdriver is used to tighten the first tightening screw  35  and the second tightening screw  36 . 
     As shown in  FIGS. 9, 11 and 13 , the present invention further provides a photographing apparatus, including a photographing device and the above quick-release assembly.
