The table top needs special treatment, has the characteristics of corrosion resistance, strong impact resistance and the like, and can be matched with different use requirements due to the selection of various table tops; the configured drawer and cabinet door are convenient for a user to store tools; a power supply hole is reserved in the table corner, and a power supply socket is convenient to install. The working table is divided into light, medium and heavy working tables and purpose-made working tables. Various wall-mounted cabinets, single cabinets, double cabinets and the like are flexibly configured according to needs, and desktop parts such as a hanging plate, an electric appliance plate, a lamp top plate, an adjusting foot cup, wheels, a shelf and the like can be additionally arranged, so that various choices are provided, and the requirements of various stations can be met. When the workbench is used in the field of part machining, people often use the workbench to carry out assembly line type assembly in order to improve production efficiency, the length of the workbench is often insufficient, the workbench needs to be additionally spliced, but the conventional workbench is not easy to be combined into a whole, the structural strength of a joint is insufficient, and actual machining and use are influenced. In addition, the workstation is bulky, occupies great space, and is inconvenient to accomodate and transport.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a car wash station [201621434702.1] comprising a plurality of car wash stations spliced together, wherein at least two car wash stations are detachably spliced together; the connecting rod piece is used for splicing and positioning two adjacent car washing platforms; one end of the connecting rod piece is a fixed end and is fixedly arranged at the bottom of the first car washing platform; the other end is a connecting end, faces and extends into the bottom of the adjacent second car washing table, the connecting end is provided with a plug head part, the thickness of the plug head part is larger than the gap between the uppermost step and the table top when the second car washing table is opened, and the thickness of the plug head part is smaller than the gap between the uppermost step and the table top when the second car washing table is folded, and when the ladder post is perpendicular to the table top, the gap between the uppermost step and the table top is smaller. According to the invention, when the second car washing platform is not completely opened, the connecting end of the connecting rod piece extends into the lower part of the second car washing platform, and after the second car washing platform is completely opened, the connecting end of the connecting rod piece is buckled and positioned by the uppermost step and the table top, so that the connection of the two car washing platforms is completed.

The problem that the workbench is inconvenient to store is solved to a certain extent by the scheme, but the scheme still has a plurality of defects, such as insufficient structural strength of joints during splicing and the like.
