DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1-5 The utility model discloses an electric stapler, including a stapler body 1, the stapler body 1 including a base 11 and an upper shell 12 arranged on the top of the base 11, a nail channel 16 is movably arranged on the top of the base 11, a nail sheet seat 15 is hinged on the top of the base 11, a driving seat 151 is arranged on the top of the nail sheet seat 15, a nail sheet 152 is arranged at the bottom of one end of the nail sheet seat 15, and the bottom end of the nail sheet seat 15 extends to the inside of the nail channel 16, and a driving mechanism 2 for driving the nail sheet seat 15 to swing back and forth is also arranged inside the upper shell 12.

[0026] The driving mechanism 2 includes a motor 21 and two driving gears 22 . The motor 21 is connected to the two driving gears 22 via a gear set 23 . An eccentric shaft 24 is disposed between the two driving gears 22 . The eccentric shaft 24 is sleeved with the driving seat 151 .

[0027] Specifically, two brackets 13 are fixedly provided inside the upper shell 12 and are respectively located on both sides of the nail channel 16. The two driving gears 22 are rotatably provided on the two brackets 13. The position of the eccentric shaft 24 is staggered from the center of the driving gear 22. The gear set 23 is rotatably provided on one of the brackets 13. The motor 21 is fixedly provided on one of the brackets 13. The motor 21, the battery 111, the switch 14 and the paddle switch 112 are electrically connected. The switch 14 is pressed to start, and the paper to be bound is inserted between the base 11 and one side of the upper shell 12 and contacts the paddle switch 112. After the paddle switch 112 is triggered, the motor 21 is started to rotate, and the motor 21 drives the two driving gears 22 to rotate through the gear set 23, and the two driving gears 22 synchronously drive the eccentric shaft 24 to rotate. When the eccentric shaft 24 rotates, it contacts the driving seat 151. When the eccentric shaft 24 is located below the center of the driving gear 22, the eccentric shaft 24 contacts the inner bottom of the driving seat 151, so that the driving seat 151 drives the nail sheet holder 15 and the nail sheet 152 to be pressed down, thereby binding the staples and the paper together. When the eccentric shaft 24 is located above the center of the driving gear 22, the eccentric shaft 24 contacts the inner top of the driving seat 151, so that the driving seat 151 drives the nail sheet holder 15 and the nail sheet 152 to rise and disengage from the staples, so that the staples at the back move forward for replenishment.

[0028] Specifically, a switch 14 is provided at the inner top of the upper shell 12, a battery 111 is provided inside the base 11, and a paddle switch 112 is provided at the top of the base 11 below one end of the nail channel 16. The setting of the paddle switch 112 eliminates the need for the user to manually control the switch 14 for binding, thereby greatly improving the binding efficiency.

[0029] Specifically, a torsion spring is provided at the hinge between the nail plate seat 15 and the base 11 , and a spring plate 17 is movably provided on the top of the base 11 . One end of the spring plate 17 is hooked and engaged with the bottom of the nail channel 16 , and the other end extends to one side of the spring plate 17 .

[0030] Specifically, a button 121 located on one side of the spring sheet 17 is movably embedded in one side of the upper shell 12. By pressing the button 121 to abut against one end of the spring sheet 17, the hook at the other end of the spring sheet 17 is disengaged from the nail channel 16. Driven by the contraction of the elastic band 18, a part pops up, and the user can pull the nail channel 16 to load staples through the push button 162. After the staples are loaded, the nail channel 16 is pushed to reset by the push button 162. The staples inside the nail channel 16 abut against the slide seat 161. The slide seat 161 pushes and stretches the elastic band 18 as the nail channel 16 is reset. The slide seat 161 continues to abut against the staples under the action of the elastic band 18, so that after one staple is used, the following staples can be replenished in time. When the nail channel 16 is re-engaged with the hook at one end of the spring sheet 17, the spring of the nail channel 16 is completed. The torsion spring is compressed when the spring sheet 17 is pressed, and the spring sheet 17 can be reset by releasing the spring sheet 17.

[0031] Specifically, a charging interface 19 located below the push button 162 is embedded on one side of the base 11 , and the battery 111 can be charged through the charging interface 19 .

[0032] Specifically, a slide seat 161 is movably provided inside the staple channel 16 , and the top of the slide seat 161 is connected to the surface of the elastic band 18 . Under the action of the elastic band 18 , the slide seat 161 continuously resists the staples.

[0033] Specifically, an elastic band 18 is further provided inside the upper shell 12, and a hanging nail located above one end of the nail channel 16 is provided inside the upper shell 12. One end of the elastic band 18 is fixed inside the upper shell 12, and the other end bypasses the hanging nail and is connected to the end of the nail channel 16 away from the hanging nail.

[0034] Specifically, a push button 162 is provided at one end of the nail channel 16 and one end of the push button 162 extends to one side of the upper shell 12 , and the push button 162 is used to facilitate pushing and pulling the nail channel 16 .

[0035] In summary, for this electric stapler, when the paper touches the toggle switch 112, the belt motor 21 is triggered to start. When the motor 21 starts, the eccentric shaft 24 touches the staple seat 15 and swings reciprocally to bind the staples to the paper. The operation method is simple and fast. The toggle switch 112 is controlled by the switch 14, adopting a double-insurance method to avoid accidental touch of the toggle switch 112. By pressing the button 121, the staple channel 16 can be ejected with one key, which facilitates the replacement of staples and makes the use more convenient. It is powered by a rechargeable battery 111, making it more portable.
