[0008] Since the first gear, the second gear, the lead screw and other devices are provided, when the user drives the second gear through the connecting shaft, since the second gear is meshed with the first gear, the first gear will also rotate, and the second gear will also drive the lead screw to rotate, so that the lead screw drives the block to move up or down. At the same time, since the driving devices are all in the device box, they will not be corroded by the liquid in the connecting box and thus be damaged, thereby increasing stability.

[0009] As a preferred technical solution of the utility model, the right side of the connecting shaft passes through the device box to be connected with the torsion switch, and a protective block is provided on the top of the screw rod.

[0010] The adoption of the above technical solution enables the user to control the device by twisting the switch when rotating the connecting shaft, thereby increasing the operability of the device.

[0011] As a preferred technical solution of the utility model, a plurality of brackets are provided on the outside of the fixed shaft, and the brackets are connected to the inner side of the device box.

[0012] The adoption of the above technical solution enables the screw and the lead screw to be threadedly connected for operation, and the bracket can enable the fixed shaft to support the screw, thereby making the operation of the device more stable.

[0013] As a preferred technical solution of the utility model, a plurality of connection columns are provided on the top of the outer side of the connection box, and the top of the connection column is bolted to the device box.

[0014] The adoption of the above technical solution can make the connection between the connection box and the device box tighter, and will also become more stable when the equipment is in operation.

[0015] As a preferred technical solution of the present utility model, the first protective pad has a certain inclination, and the third protective pad on the right side of the stopper also has a certain inclination.

[0016] The adoption of the above technical solution can make the block fit the water inlet and the water outlet perfectly without causing damage to the surface of the device.

[0017] As a preferred technical solution of the present utility model, the bottom of the connection box is connected to the bottom shell, and the top of the bottom shell supports the water inlet and the water outlet.

[0018] The above technical solution enables the user to disassemble the inside of the connection box by disassembling the bottom shell, and when the device is running, the bottom shell can effectively protect the water inlet and the water outlet.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. Due to the arrangement of the first gear, the second gear and the lead screw, when the user drives the second gear through the connecting shaft, the second gear meshes with the first gear, so the first gear will also rotate, and the second gear will also drive the lead screw to rotate, so that the lead screw drives the block to move up or down. At the same time, since the driving devices are all in the device box, they will not be corroded by the liquid in the connection box and thus be damaged, thereby increasing stability;

[0021] 2. Through the setting of the device box, when the user replaces the parts inside the device box, it will not affect the equipment inside the connection box, and the device box can effectively protect the driving components. Through the first protective pad, the second protective pad, the third protective pad and other devices, the block can perfectly fit the water inlet and the water outlet without damaging the surface of the device.
