To improve precision in the injection amount of a fuel injection valve, the opening and closing action of a valve body must be performed quickly. In a structure in which the fluid force produced in a seat of a valve body is not transmitted immediately after a needle begins to move, adhesion between an end surface of an anchor and an end surface of a stationary core must be impeded and these end surfaces must be prevented from sticking together. To solve this problem, the present invention is a structure in which a valve body of an electromagnetic fuel injection valve comprises a second valve body in contact with the anchor when the valve is closed, and a first valve body in contact with the anchor while the valve is opening. The second valve body comes in contact with a stroke stopper disposed on the inner periphery of the stationary core when the valve opens, the lengths of the first valve body and the second valve body are stipulated so that the stationary core and the anchor do not come into direct contact and a gap is ensured when the valve opens, and the process of plating the stationary core and the anchor is discontinued.

One side of the pressure bearing plate is connected to the buffer piece and the other side is in conflict with the side wall of the lock tongue. The present invention has the effect that the dead bolt is easily reset by the staff member turning the dead bolt internally through the driving assembly.

The invention belongs to the technical field of robots, and particularly relates to an electric gripper device, which includes: a base frame; two hypocycloidal gear sets, the hypocycloidal gear sets include an external gear and an internal gear, and the diameter of the pitch circle of the external gear is Twice the diameter of the pitch circle of the inner gear, the outer gear meshes with the inner gear, and the outer gear is fixed on the base frame; two output connectors, the first end of the output connector is fixed at the center of the inner gear, and the output connector The second end is provided with a positioning column; the guide rail includes a linear guide groove, and the two positioning columns slide through the linear guide groove; two jaw execution parts, and the two jaw execution parts are respectively connected with the two positioning columns; The drive assembly is used to drive two hypocycloid gear sets and make the centers of the two internal gears rotate synchronously around the centers of the corresponding external gears, so as to realize the opening and closing action of the jaws and eliminate the movement of the linkage mechanism of the existing electric jaws singular point.

The invention provides an image forming device. The drive transmission unit included in the image forming apparatus includes a first drive transmission unit and a second drive transmission unit. The first drive transmission unit transmits the rotational driving force of the motor rotating in the first rotational direction to the toner container, thereby conveying the toner contained in the toner container in a predetermined direction, and restricting the The rotational driving force of the motor rotating in the second rotational direction is transmitted to the toner container. The second drive transmission part transmits the rotational driving force of the motor rotating in the second rotation direction to the container cover, thereby changing the state of the container cover from the closed state to the open state, and restricting the movement to the container cover. The rotational driving force of the motor rotating in the first rotational direction is transmitted to the container cover. Accordingly, the opening and closing operation of the container cover for opening the toner container to the outside can be realized at low cost.

The invention relates to an air conditioner. The air conditioner provided in the invention is characterized by including the components as following: a body, which possesses an air discharge portion for discharging air after conditioning; an open / close panel, which is arranged to be movable for opening the air discharge portion; a driving portion, which is used for driving the open / close panel; a first gear, which can be driven by the driving portion to rotate; a movement guiding portion, which possesses a second gear which is linked to the first gear and can move linearly; and a fixation guiding protion, which fixes the body and possesses a floating-prevented portion for guiding the movement guiding portion to move. A guiding channel is formed on the movement guiding portion for accommodating at least part of the movement guiding portion.

The invention discloses a bag receiving and opening device of a packing machine, and belongs to the field of packing machines. The device comprises a bag receiving and conveying mechanism and a bag opening mechanism; the bag receiving and conveying mechanism includes a bag bearing plate, and a translation mechanism capable of enabling the bag bearing plate to perform a reciprocating motion between a bag receiving station and a bag opening station; the bag bearing plate is provided with an absorbing hole in one side corresponding to the position of a bag opening of a prefabricated bag; the bag opening mechanism includes a bag opening jaw; and the side surface of the bag opening jaw is arched.
