The baffle is used for sheltering from the pressure section of presser foot to it is impaired to avoid the pressure section to receive external contact.
Preferably, the first shell is provided with a notch for avoiding the pressure foot, and the first shell and the second shell are fixed so that the side wall of the connecting section of the pressure foot is contacted with the side wall of the first shell. The arrangement is used for limiting the inclined deformation of the connecting section so as to ensure the pressing of the pressing section on the circuit board.
Preferably, the second shell is provided with two press feet, and the press feet are contacted with the edge of the circuit board. The contact area of the presser foot and the circuit board is increased under the condition of minimum consumable materials by the arrangement, so that the pressing and fixing effects of the circuit board are guaranteed.
The utility model has the advantages of the circuit board is fixed more stable, the controller uses more stable.
