Problems solved by technology

Due to the whole process from the output power of the motor to the final driving of the staple sheet to press the needle down out of the needle slot, the force is a rigid transmission process, which has the following technical disadvantages: 1) due to the limitation of the motor, structure and cost, generally Electric staplers can only staple 2 to 20 sheets of paper. Under the current deceleration and force-increasing conditions, in order to increase the number of staples, a motor with a larger power and size is required, which will increase the size of the stapler.
2) The needle force is continuously acting on the needle during half of the needle cycle. When the needle is soft and the needle is blunt, the effect of the needle becomes poor, and the needle may not penetrate the paper, and the needle may be caught in the paper. Faults in the book needle slot, etc.
3) When the book needle is clamped in the book needle groove, the staple piece can no longer move down, nor can it return to the initial state, but because a staple cycle is not completed, the circuit breaker will not be disconnected, and the motor will continue to work and will Increasing the output load often leads to burning out the motor
4) Moreover, due to the limitation of the gear set and the box structure, once the needle is clamped, it is generally difficult for the electric stapler to pop out the needle slot and take out the clamped needle
However, the elastic sleeve of this type of model must be made of special memory elastic material, which has defects such as high material cost, difficult control of processing size, and high production cost.

Abstract

The invention relates to an electric energy storage stapling machine, comprising a box which contains a control switch and a circuit, a motor, a gear group for reducing speed and increasing force, and a wheel. The last wheel of the gear group is concentric with the wheel and connected via an eccentric axle, the box contains sliding engaged staple groove and stapling device with some angle, the box contains a flexible energy storage device, a locking releaser for locking and releasing the stapling machine, the middle of the flexible energy storage device is hinged between two inner side walls of the box while its outer end is hooked on the stapling machine and inner end is directly or indirectly hinged on the eccentric axle, the circumference of the wheel is disposed with a dial block for dialing block and locking block and a dial rod for dialing the control switch. The invention has low demand on motor power, and low cost, which it can avoid destroying motor in clamped condition.

Description

technical field [0001] The present invention relates to an office stationery, more specifically, the present invention relates to an electric stapler. Background technique [0002] All staplers have to go through the cycle process of pressing the staples downward and then rising back to the highest position. During this process, the staples may be caught in the staple slots and difficult to remove, resulting in the staple sheet not being able to return. The failure of the initial position, especially for electric staplers, the stapler is installed in the stapler. Once the stapler is stuck or the needle is clamped, the entire stapler will be linked and difficult to recover and raised to the highest level. Position; the existing electric stapler, when the needle is clamped in the needle groove, according to the way the stapler returns to the initial position and the structure is different, it can be divided into motor reverse type electric stapler and The mechanically control...
