Among many beauty equipment, the leg beauty equipment for leg line exercise occupies an important position. However, there are some problems with the existing leg beauty equipment on the market, such as complex product structure, cumbersome operation, and the need for users to actively exert force for exercise.

[0003] For example, the utility model with the Chinese patent application number CN202320149126.X specifically relates to a lower limb stretching trainer, which includes a support rod, a support beam, and a cotton pad. The four support rods are supported on both sides, and each side is connected by two rods through hinges and inserts. The bottom end of the right support rod is connected to the support beam, and the bottom end of the left support rod is connected to a roller. Although the above trainer can build the lower limbs, it requires users to actively exert force for exercise to achieve the leg beauty effect, which greatly reduces the user experience during use. Summary of the Utility Model

[0008] Two support seats are provided at the middle part of the frame at intervals left and right, and a crank mechanism is rotatably connected to the two support seats;

[0009] The rear sides of the two leg placement boxes are respectively movably connected to the left and right output ends of the crank mechanism through connecting rods;

[0010] A driving mechanism for driving the circumferential movement of the crank mechanism is further provided at the lower part of the frame, and the output end of the driving mechanism is connected to the crank mechanism, thereby driving each connecting rod to push the two leg placement boxes back and forth.

[0011] Compared with the prior art, the advantages of the utility model are as follows:

[0012] 1. Through the cooperation of the crank mechanism and the connecting rod, each connecting rod is driven by the crank mechanism to push two leg placement boxes forward and backward, enabling the user to perform beautiful leg exercises by shaking the legs with the forward and backward movement of the leg placement boxes without having to exert force independently during use.

[0013] 2. The utility model is provided with a driving mechanism to drive the circumferential movement of the crank mechanism, and then drive the connecting rod to push the leg placement box forward and backward. Its structure is simple, the operation is convenient, and the force transmission path is clear, greatly improving the user experience. BRIEF DESCRIPTION OF THE DRAWINGS
