The invention discloses a novel coating device. The novel coating device comprises a base, wherein support plates are vertically arranged on the left and right sides of the top of the base, and transparent plastic plates are vertically arranged on the front and rear sides of the top of the base; a worktable is arranged between the support plates, a hydraulic telescopic rod is arranged at the bottom of the worktable and is hollow, the worktable is hollow, a double-rod hydraulic cylinder is arranged in the worktable, piston rods are arranged at two ends of the double-rod hydraulic cylinder, andL-shaped clamp blocks are connected to the end parts of the piston rods; first slide chutes are formed in the support plates, and cover plates are arranged at the tops of the support plates; and a slide rail is arranged at the top of the worktable, and a slide block is arranged on the slide rail. According to the novel coating device, the situation that the working environment is polluted by harmful gas dispersed from a coating can be avoided, so that the potential threats of the body health of workers are reduced; meanwhile, the spattering of the coating in the coating process can be prevented, so that a procedure for cleaning the spattered coating in a later stage is omitted; and the novel coating device is strong in applicability and can be popularized and used.
