[0006] The reciprocating assembly includes a rack mounted on a fixed frame, a rotating rod is rotatably connected to the limiting column, a half gear is fixedly connected to the rotating rod, a tension spring is fixedly connected between the fixed frame and the mounting frame, a crank handle is fixedly connected to one end of the rotating rod, and the teeth of the half gear are meshed with the teeth of the rack.

[0007] Optionally, the mounting frame includes a bottom plate, a connecting column is connected to the bottom plate, a top plate is fixedly connected to the connecting column, and the rack passes through the top plate.

[0008] Optionally, the fixing bracket comprises a mounting plate, a threaded rod is fixedly connected to the mounting plate, a clamping plate is slidably connected to the threaded rod, and a nut is threadedly connected to the threaded rod.

[0009] Optionally, there are multiple groups of tension springs, and the tension springs are evenly distributed on both sides of the fixing frame.

[0010] Optionally, the crank handle comprises a crank fixedly connected to one end of a rotating rod, and a handle is rotatably connected to the crank.

[0011] Optionally, the rotation diameter of the half gear is smaller than the length of the limiting column.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model drives the rack to move upward through the half gear. When the rack drives the fixed frame to reach the highest point, the teeth of the half gear are separated from the rack. Under the tension of the tension spring and the self-gravity of the fixed frame, the fixed frame hits the limit column, and a good screening effect is guaranteed through reciprocating impact. Since the device is a purely mechanical device and is not limited by power supply, the use place and position are more flexible, and the size can be customized according to the use environment, thereby fully realizing the portability effect.
