DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 The utility model provides a new technical solution: an electric scissors device with a protective mechanism, comprising a housing 1, a tool movement device is arranged inside the housing 1, a maintenance device is arranged outside the housing 1, and a protective mechanism is arranged at the front of the housing 1;

[0024] The tool movement device includes a rectangular plate 3, a motor 4 is fixedly connected to the upper surface of the rectangular plate 3, a control box 14 is fixedly connected to the lower surface of the rectangular plate 3, a first bevel gear 5 is fixedly connected to the output shaft of the motor 4, a first transmission shaft 7 is rotatably sleeved on the outer surface of the inner support frame 2, a second bevel gear 6 is fixedly connected to the outer surface of the first transmission shaft 7, and the first bevel gear 5 is meshedly connected with the second bevel gear 6;

[0025] Among them, the first transmission shaft 7 extends to one end of the inner support frame 2 and is fixedly sleeved with a gear 8, the outer surface of the inner support frame 2 is fixedly connected with a second transmission shaft 10, the outer surface of the inner support frame 2 is bolted with a fixed blade 15, the outer surface of the second transmission shaft is rotatably sleeved with a fan gear 9, the gear 8 is meshed with the fan gear 9, the outer surface of the fan gear 9 is fixedly connected with a limiting column 13, the movable blade 12 is screwed to the outer surface of the fan gear 9, and a screw 11 is provided between the fan gear 9 and the movable blade 12. This design facilitates the removal of the blade. Due to the start-up of the motor 4, the first bevel gear 5 is driven to rotate through the output shaft of the motor 4, and then the first transmission shaft 7 is driven to rotate through the meshing of the first bevel gear 5 and the second bevel gear 6;

[0026] Among them, the rotation of the first transmission shaft 7 drives the rotation of the gear 8, and then the engagement of the gear 8 with the fan gear 9 drives the rotation of the fan gear 9. Since the fan gear 9 is an incomplete fan gear, the movable blade 12 swings up and down, and the movable blade 12 cooperates with the fixed blade 15 to achieve the shearing work. Since the movable blade 12 and the fixed blade 15 are both arranged to be bolted, it is convenient to disassemble the tool. When the tool shearing encounters difficulties or the shearing encounters a dangerous situation, the control system of the control box 14 senses that its shearing force is too large, and the control module of the control box 14 will send a shutdown command to the motor 4 to avoid damage to the existing shearing equipment motor due to overload operation and safety problems encountered in shearing, thereby improving the service life of the motor and the safety of the staff.

[0027] Furthermore, the maintenance-friendly device includes a cover plate 17, which is screwed to the side surface of the shell 1, and a threaded hole group 16 is provided on the upper surface of the cover plate 17, and the corresponding side surface of the shell 1 is provided with the same threaded hole group 16. When the operator needs maintenance, he only needs to unscrew the screws and remove the cover plate 17, and then add lubricating oil and remove the blade, thereby avoiding the inconvenience of replacing props of the existing shearing equipment, complicated maintenance work, and reduced work efficiency. It provides convenience for the operator, reduces the operator's workload, and improves work efficiency.

[0028] Furthermore, the protective mechanism includes a protective cover 22, which is fixedly connected to the outer surface of the housing 1. When the tool is shearing, it prevents the impact generated when shearing the workpiece and the flying chips from causing damage to the operator. On the other hand, it also prevents the operator from touching the blade during use and causing scratches on the body, thereby improving its safety performance.

[0029] Furthermore, a switch 19 is slidably connected to the outer surface of the shell 1, a cover plate 17 is fixedly connected to the upper surface of the shell 1, a charging port 20 and a power cord outlet 21 are provided on the rear side of the shell 1, and a fingerprint recognition mechanism 18 is fixedly connected to the upper surface of the shell 1. The control box 14 is used to control the fingerprint recognition mechanism 18. The mechanism can be charged and can also work using a power cord, thereby improving the performance of the device and the versatility of use. The switch 19 and the cover plate 17 are both electrically connected to the control module of the control box 14. When using the device, fingerprint recognition must be performed first. Long press the cover plate 17 for fingerprint recognition. Only when the fingerprint recognition is passed can the switch 19 play a control role. When the switch 19 is pressed, the device is started, and the switch 19 is pressed again to turn off the device.

[0030] Working principle: When using the device, first perform fingerprint recognition, and long press the cover 17 for fingerprint recognition. When the fingerprint recognition is passed, the switch 19 can play a control role. When the switch 19 is pressed, the device is started, and the switch 19 is pressed again to turn off the device. When the switch 19 is turned once, the device is started, and the control module in the control box 14 sends a start command to the motor 4, and the motor 4 starts to work. The output shaft of the motor 4 drives the rotation of the first bevel gear 5, and then the first bevel gear 5 is engaged with the second bevel gear 6 to drive the rotation of the first transmission shaft 7. The rotation of the first transmission shaft 7 drives the rotation of the gear 8, and then the gear 8 is engaged with the fan gear 9 to drive the rotation of the fan gear 9. Since the fan gear 9 is an incomplete fan gear, the movable blade 12 swings up and down, and the movable blade 12 cooperates with the fixed blade 15 to achieve shearing.

[0031] Furthermore, when an emergency situation occurs where the shearing force is overloaded, the control system of the control box 14 senses that the shearing force is too large, and the control module of the control box 14 will issue a shutdown command to the motor 4 to avoid damage to the existing shearing equipment motor due to overload operation and safety problems encountered in shearing.

[0032] Furthermore, when the operator needs to perform maintenance, he only needs to unscrew the screws, remove the cover plate 17, add lubricating oil, and remove the blade.

[0033] Furthermore, when charging is needed, the charging power cord is inserted into the charging port 20 to achieve charging. When high power or heavy load work is required, the power cord at the power cord outlet 21 is used to plug in and work.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
