The scissor frame 17 is driven to extend and retract vertically by a power unit. Below the base frame 16 are a push rod shaft 18 for connecting the production line chain and rollers 19 for rolling on the production line platform. The power unit drives the scissor frame 17 to extend and retract vertically, thereby enabling the worktable 1 to move up and down. The base frame 16 moves with the production line chain via the push shaft 18, and the rollers 19 roll on the production line platform.

[0037] The specific structure of the scissor frame 17: The scissor frame 17 includes a front scissor assembly and a rear scissor assembly.
