In addition, the second end and the fourth end, at which the first binding staple receiving groove 244 and the second binding staple receiving groove 245 are respectively formed, are respectively adjacent to the driving part 230. For example, the first and second strapping

To facilitate a clearer understanding of the present embodiment, a detailed description of a specific binding action process of the electric binding machine 200 of the present embodiment is given below:

after the binding nails are preset in the binding nail accommodating grooves 243, the driving motor 221 is started to rotate the motor shaft in the clockwise direction. At this time, the main transmission member 222 is driven by the motor shaft to rotate clockwise, so as to drive the first transmission member 231 in transmission connection therewith to rotate counterclockwise, and at the same time, the first bundling member 241 in transmission connection therewith rotates clockwise, at this time, the second end is close to the fourth end, so that the bundling jaw is continuously reduced; meanwhile, the second transmission member 232 is driven by the first transmission member 231 to rotate clockwise, so as to drive the second bundling member 242 to rotate counterclockwise, so that the fourth end is close to the second end, the bundling opening is further narrowed, the bundling opening is closed until the bundling space is compressed, and the bundling nail completes the bundling action along with the intersection and coincidence of the second end and the fourth end.

And oppositely, the motor shaft rotates towards the anticlockwise direction, so that the second end and the fourth end are far away from each other until the initial position is restored. The specific process is the same as the above binding process, and is not described herein again.

Preferably, the main transmission member 222, the first transmission member 231 and the second transmission member 232 are respectively of a gear structure. A first rack which is externally meshed with the first transmission piece 231 is arranged at the first end of the first bundling piece 241; the third end of the second bundling member 242 is provided with a second rack gear externally engaged with the second transmission member 232.

The working process of the binding nail feeding part 250 is specifically as follows: a predetermined set of binding nails is provided on the binding nail mounting member 251, and one of the binding nails is mounted in the binding nail mounting groove 243 by moving the movable limiting member 252 to approach one side of the binding portion 230 under the elastic action of the second elastic member 253. When the binding portion 230 performs one binding operation, the binding nail binds to the target object, and the movable limiting member 252 is continuously pushed by the elasticity of the second elastic member 253 to slide the remaining binding nail group toward the side close to the binding 230, and then one of the binding nails is positioned in the binding nail mounting groove 243, so that the binding portion 240 binds to the next target object.

The specific operation of installing the rechargeable power supply 201 on the installation casing 210 is as follows: applying a force to the operating member 262 to press the first elastic member 263, so that the stop block 261 is hidden in the space, and the slider 12 of the rechargeable power supply 201 is arranged on the mounting housing 210 along the length direction of the slide rail 216 until the power supply groove 11 is matched and connected with the electric connection terminal 217; and releasing the pressure, so that the limit block 261 protrudes from the slide rail 216 and is connected with the limit groove 13 in a matching manner, and the limit effect on the rechargeable power supply 201 is further realized.

[ second embodiment ]

Referring to fig. 11-12, a structure of a rechargeable battery pack 100 according to a second embodiment of the present invention is schematically shown. The rechargeable battery pack 100 may be used as the rechargeable power source 201 of the electric power binding machine 200 as described in the first embodiment above.

With continued reference to fig. 12, the power supply mounting case 10 includes, for example, a slider 12, and a stopper groove 13 provided on the slider 12. For example, when the rechargeable battery pack 100 is connected to an electrical appliance having a slide rail cooperatively connected with the slide block 12, the rechargeable battery pack 100 is disposed on the slide rail in the connection process, so that the slide block 12 is cooperatively connected with the slide rail to push the rechargeable battery pack 100 to slide to the power supply groove 11 and the portion of the electrical appliance cooperatively connected with the electrical appliance, and at this time, the two plug terminals 31 are connected to the power connection terminals of the electrical appliance to supply power to the electrical appliance.

Furthermore, the limiting groove 13 enables the rechargeable battery 100 to be installed on the electrical appliance, and the rechargeable battery 100 is connected with the limiting part of the electrical appliance in a matching manner, so that the connection between the rechargeable battery and the limiting part is more stable, and the rechargeable battery 100 is not easy to fall off from the installation position of the electrical appliance.

Preferably, the charging circuit board 30 is further provided with a plurality of display lamps 34 and a switch 35, for example. The plurality of display lamps 34 are used to display the power condition of the rechargeable battery pack 100. For example, each of the display lamps 34 represents the same charge of the rechargeable battery pack 100, when the rechargeable battery pack 100 is fully charged, the plurality of display lamps 34 are all on, and when the accumulated decreased charge is greater than the charge represented by one of the display lamps 34, one of the display lamps 34 is turned off; when the accumulated decreased amount of electricity is larger than the amounts of electricity represented by the two indicator lights 34, one indicator light 34 is turned off until all indicator lights are turned off.

Referring to fig. 13, each plug connector 31 preferably includes, for example, a first plug portion 32 for mating connection with the electrical appliance and a second plug portion 33 for connecting the first plug portion 32. Wherein the first plug part 32 is connected with the second plug part 33 at a certain angle. For example, when the first plugging portion 32 is used for connecting the electrical appliance, the contact surface of the first plugging portion and the electrical appliance is relatively larger and the contact point is tighter due to the squeezing effect, so that poor contact caused by loose plugging points in a long-term plugging process is prevented.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
