持機構、８：スイツチ操作機構。 The drawings show an embodiment of the present invention, in which Fig. 1 is a partially cutaway front view showing the state when not in use, Fig. 2 is a partially cutaway side view of the same, Fig. 3 is a perspective view showing the connector, and Fig. 4 is a partially cutaway front view showing the state when not in use. The figure shows a partially cutaway front view of the operating lever being pulled up and the striking hammer descends to strike the needle and the switch is turned on. Figure 5 is a partially cutaway front view of the striking hammer being pushed up. Figure 6 is a partially cutaway front view of the striking hammer. Partially cutaway front view showing the state where the switch is held near the top dead center and the switch is turned OFF, Figures 7 to 10
The figures show the switch plate, connector plate, and
FIG. 3 is a cross-sectional view showing the relationship between the hammer cam and the switch. In the figure, 2: motor, 3: switch, 4: impact hammer, 5: spring, 6: driving member, 7: holding mechanism, 8: switch operation mechanism.

Claims

[Scope of Claim for Utility Model Registration] (1) A hammer for striking the needle, a spring that biases the hammer in the direction of striking the needle, and a drive that moves the striking hammer in the direction of the spring's energy storage by rotation of a motor. member, a holding mechanism that latches and holds the striking hammer, which is moved in the direction of storing force of the spring by the operation of the driving member, at a predetermined position at the top dead center, and the holding mechanism is operated in conjunction with the ON/OFF operation of the switch. An electric tatsucar characterized by comprising a switch operation mechanism for controlling the operation. (2) The electric tucker according to claim 1, wherein the elastic force of the spring is adjustable from the outside.
