The outer side of the clamping plate 3315 is provided with an elastic buckle 3316, and the clamping plate 3315 and the elastic buckle 3316 are used to fixedly connect the support plate 331 and the follower gear 332.

[0044] The follower gear 332 is provided with a tooth surface 3321 on the side opposite to the driving gear 322, and the tooth surface 3321 is configured as a turbine gear that can be engaged with the worm gear, so that the follower gear 332 can be driven to rotate by the driving gear 322. The follower gear 332 is also provided with a clamping groove 3322 matched with the shape of the clamping plate 3315, and the clamping groove 3322 is arranged away from the tooth surface 3321. When the clamping groove 3322 is adaptively connected with the clamping plate 3315, the elastic buckle 3316 can be buckled on the outer wall of the clamping groove 3322, so as to increase the connection strength between the support plate 331 and the follower gear 332.

[0045] The box shape of the drive box 340 is matched with the inner cavity shape of the cavity 110, so that the drive box 340 can be detachably connected in the cavity 110 on either side of the body 100. The drive box 340 is provided with a drive rod 341, which in this embodiment includes a first body 3411 and a second body 3412. One end of the first body 3411 forms a drive wheel 3413, which is drivingly connected to a motor 343 through a gear set 342. It can be understood that the motor 343 is fixed in the drive box 340, and the motor 343 can be electrically connected to the control box 120 through the first conductive plug 344. Specifically, the first conductive plug 344 is provided on the drive box 340, and when the drive box 340 is fixed in any cavity 110, the first conductive plug 344 can be connected to the conductive connector 121 through the second connecting hole 112, so that the motor 343 can be electrically connected to the control circuit, and the motor 343 can be controlled to start or stop.

[0046] The second body 3412 is movably sleeved on the other end of the first body 2411, and a clutch structure is arranged between the second body 3412 and the first body 3411, the clutch structure includes a first clutch tooth 3414 fixed on the first body 3411 and a second clutch tooth 3415 fixed on the second body 3412, the first clutch tooth 3414 and the second clutch tooth 3415 are in meshing engagement. The movable head 3416 is movably connected to the second body 3412 through the elastic member 345, the movable head 3416 is circumferentially fixed to the second body 3412 and is detachably fixedly fitted in the groove 3231. When the drive box 340 is fixed in any cavity 110, the movable head 3416 can pass through the first connecting hole 111 and be inserted into the groove 3231, so as to drive the engagement tooth 323 to rotate when the drive rod 341 is controlled to rotate. If the drive box 340 is pulled out of the cavity 110, the movable head 3416 can be separated from the groove 3231.

[0047] It should be noted that the above settings of the first body 3411, the second body 3412 and the movable head 3416 can achieve the purpose of driving the movable head 3416 to rotate to drive the access tooth 323 to rotate through the clutch structure between the first body 3411 and the second body 3412, and can also drive the first body 3411 to rotate under the drive of the motor 343 to prevent the motor 343 from being stuck and burned in the case that the access tooth 323 is limited and cannot rotate. On the other hand, through the elastic movement cooperation between the movable head 3416 and the second body 3412, it can be ensured that the movable head 3416 can be correctly clamped in the groove 3231 during fixing the drive box 340 in the cavity 110. This is because the movable head 3416 can be elastically moved, so that the movable head 3416 can be compressed when it touches the outer wall of other structures, until the movable head 3416 is opposite to the groove 3231, then the movable head 3416 can be elastically extended and clamped in the groove 3231, which plays a role in guiding and aligning connection.

[0048] It can be understood that in the embodiment, the other end of the drive box 340 opposite to the movable head 3416 is detachably connected with a decorative cover 346, which can increase the appearance and facilitate the player to hold and move the drive box 340. In other embodiments of the utility model, the drive box 340 can not be provided with the decorative cover 346.

[0049] The box shape of the control box 350 is matched with the inner cavity shape of the cavity 110, so that the control box 350 can be detachably connected in the cavity 110 on any side of the body 100. The control box 350 is provided with an electrically connected second conductive plug 351 and a key assembly 352, and the second conductive plug 351 is arranged outside the control box 350. When the control box 350 is fixed in any cavity 110, the second conductive plug 351 can be electrically connected to the conductive connector 121 through the second connecting hole 112, so that the key assembly 352 can be connected to the control circuit, and then the key assembly 352 can control the start and stop, left rotation and right rotation of the motor 343. It can be understood that the key assembly 352 is arranged outside the cavity 110, so as to facilitate the player to press and operate.

[0050] The working principle of the driving structure provided by the embodiment is that when the driving box 340 and the control box 350 are both inserted into the cavity 110, the motor 343 of the driving box 340 is electrically connected to the electric control box 120 through the first conductive plug 344, and the key assembly 352 of the control box 350 is electrically connected to the electric control box 120 through the second conductive plug 351, so that the key assembly 352 and the motor 343 can be electrically connected into a closed loop, and then the working state of the motor 343 can be controlled through the key assembly 352. At this time, the movable head 3416 is clamped in the groove 3231, and when the motor 343 is started to rotate left or right, the motor 343 can drive the first main body 3411 to drive the second main body 3412 to rotate through the gear set 342, so that the movable head 3416 can drive the access tooth 323 to rotate, and then drive the driving tooth 322 to rotate through the transmission tooth 324, so that the driving tooth 322 can drive the finger mechanism 200 on the support plate 331 to rotate through the driving tooth 322, and then the finger mechanism 200 can present the action of turning up and down. If the support plate 331 rotates to the limit position, the driving tooth 322, the transmission tooth 324, the access tooth 323, the movable head 3416 and the second main body 3412 are all in a state of being unable to rotate, at this time, under the action of the elastic member 345, the first main body 3411 can still rotate relative to the second main body 3412 to ensure the normal work of the motor 343, at this time, the motor 343 can be controlled to stop rotating through the key assembly 352, so as to complete the action of electrically controlling the finger to turn.

[0051] Please refer to Figures 10 to 11 , the driving box structure of another embodiment of the utility model is shown. Among them, the driving box 340 is not provided with the gear set 342, the motor 343 and the first conductive plug 344, and the structure of the driving rod 341 is also different from that of the driving rod structure of the previous embodiment.

[0052] Specifically, the driving rod 341 is rotatably penetrated through both ends of the driving box 340, and the driving rod 341 includes a first protruding end 3417 and a second protruding end 3418 which are respectively exposed to the outside of the driving box 340. The first protruding end 3417 can be exposed on the body 100 and detachably fixed with the decorative cover 346, so that the player can conveniently rotate the driving rod 341 by rotating the decorative cover 346. The movable head 3416 is movably connected to the second protruding end 3418 through the elastic member 345 on the second protruding end 3418. The movable head 3416 is recessed with a sliding groove 3419, which is connected with the limiting block 3410 of the second protruding end 3418 through the sliding groove 3419, so that the movable head 3416 can be movably connected to the second protruding end 3418 and fixed with the second protruding end 3418 in the circumferential direction.

[0053] It should be noted that the movable head 3416 is detachably fixed in the groove 3231, and when the drive box 340 is inserted and fixed in any cavity 110, the movable head 3416 is clamped and fixed with the groove 3231.
