The invention discloses an intelligent joint film-coating device suitable for grape grafting. The intelligent joint film-coating device comprises a base, wherein an elastic wrist tie band is arranged on one side of the base, an elastic fingerstall is arranged on the side, close to the elastic wrist tie band, of the base, a control switch is arranged on the side, close to the elastic fingerstall, of the base, a second fixing boss is arranged on the side, close to a supporting plate, of the base, and the side, away from the base, of the second fixing boss is connected with one end of a first electric telescoping rod. By arranging a first fixing boss, a first electric telescoping rod, a first fixing press plate, a second fixing press plate, the second fixing boss, a soft press pad and a control switch, the first electric telescoping rod is opened through the control switch, the first electric telescoping rod pushes the first fixing press plate and the second fixing press plate which are connected to fix the position of a joint for grafting two positions, the soft press pad prevents the joint for grafting the two positions from rotating relatively, convenience is brought to grafting, and a better grafting effect is achieved.
