[0013] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0014] Example 1 like Figure 1-4 As shown, this embodiment discloses a driving device for a crab simulation colored light, including: a torso frame 1, a crankshaft 2, a pincer 3, a leg rod 4, a swing assembly 5, and a drive motor 6. The two ends of the crankshaft 2 are respectively disposed at the front and rear ends of the torso frame 1. The drive motor 6 is disposed on the torso frame 1, and its output end is connected to the main journal of the crankshaft 2 through a first chain and sprocket assembly 7. A first connecting rod 9 is connected to the connecting rod journal of the crankshaft 2. The other end of the first connecting rod 9 is connected to one end of a leg connecting rod 10. The middle part of the leg connecting rod 10 is rotatably connected to the torso frame 1. The other end of the leg connecting rod 10 is connected to the leg rod 4. The swing assembly 5 is connected to the crankshaft 2 through a second chain and sprocket assembly 8. The pincer 3 is disposed on the swing assembly 5.

[0015] In use, the drive motor 6 is started first. The output end of the drive motor 6 drives the crankshaft 2 to rotate through the first chain and sprocket assembly 7. The rotation of the crankshaft 2 drives the first connecting rod 9 to move up and down in the vertical direction, which in turn pulls the end of the leg link 10 connected to the first connecting rod 9 to swing up and down. The middle part of the leg link 10 is rotatably connected to the torso frame 1. The other end of the leg link 10 and the end connected to the first connecting rod 9 form a reverse linkage, so that the leg link 10 moves in a seesaw manner, which finally drives the leg rod 4 to swing up and down to simulate the walking posture of a crab.

[0016] The rotation of crankshaft 2 will also drive the swing assembly 5 to swing left and right in the horizontal direction through the second chain sprocket assembly 8. The pincers 3 are set on the swing assembly 5 and will swing left and right together with the swing assembly 5 to simulate the posture of a crab waving its pincers.

[0017] Example 2 like Figure 1-4As shown, this embodiment is based on embodiment one. The swing assembly 5 includes two swing plates 51. One end of the two swing plates 51 is connected by a swing connecting rod 52. The other end of the two swing plates 51 is rotatably connected to the torso frame 1 by an inner connecting rod 53. The clamp 3 is sleeved on the inner connecting rod 53. A transmission rod 54 is sleeved on the swing connecting rod 52. The other end of the transmission rod 54 is connected to a transmission shaft 55 by a second connecting rod 56. The transmission shaft 55 is disposed on the torso frame 1. The transmission shaft 55 is connected to the crankshaft 2 by a second chain and sprocket assembly 8.

[0018] The crankshaft 2 rotates, driving the transmission shaft 55 to rotate via the second chain and sprocket assembly 8. One end of the second connecting rod 56 is fixedly connected to the transmission shaft 55, and the other end is sleeved on the transmission rod 54. The rotation of the transmission shaft 55 drives the second connecting rod 56 to rotate, which in turn drives the transmission rod 54 to slide up and down on the swinging connecting rod 52 and swing the swinging connecting rod 52 left and right. The swing plate 51 then swings left and right around the connection point between the inner connecting rod 53 and the torso frame 1, causing the inner connecting rod 53 to swing left and right, which in turn causes the clamp 3 to swing left and right.

[0019] Furthermore, the torso frame 1 has an extension plate 11 extending outward in the front direction, and the swing plate 51 is rotatably connected to the extension plate 11.

[0020] Furthermore, the axis of the middle part of the inner connecting rod 53 is offset from that of the end part of the inner connecting rod 53, so that the middle part can swing when the two ends of the inner connecting rod 53 rotate.

[0021] Example 3 like Figure 1-4 As shown, this embodiment is based on Embodiment 1. The torso frame 1 includes an upper frame 12 and a lower frame 13. Several crossbars 14 are spaced apart on the upper frame 12, and bearing mounting seats 15 are provided on the crossbars 14. The main shaft of the crankshaft 2 passes through the bearing mounting seats 15. The crankshaft 2 is mounted through the bearing mounting seats 15, ensuring the installation stability of the crankshaft 2.

[0022] Example 4 like Figure 1-4 As shown, this embodiment is based on Embodiment 1. A cylinder 16 is sleeved in the middle of the leg link 10. The cylinder 16 is rotatably connected to a second bearing mounting seat 17, which is disposed on the torso frame 1. By rotatably connecting the cylinder 16 to the second bearing mounting seat 17, the middle of the leg link 10 can rotate to form a seesaw-like structure.

[0023] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
