[0028] 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.

[0029] Reference Figure 1-3 The utility model provides an embodiment: an electric ear tag pliers with adjustable stroke, comprising a fixed jaw 1, a swinging jaw 2 is provided on the fixed jaw 1, a trigger 3 is provided under the fixed jaw 1, a housing 4 is provided on the trigger 3, a gear 5 is provided in the housing 4, a rack 6 is provided under the swinging jaw 2, a first control board 7 is provided in the housing 4, a second control board 8 is provided on the fixed jaw 1, a wear-resistant washer 9 is provided on the swinging jaw 2, a reducer 10 is provided in the housing 4, a motor 11 is provided in the housing 4, a battery 12 is provided in the housing 4, and the fixed jaw 1 A first rotating shaft 13 is provided on the rack 6, a tightening bolt is provided on the rack 6, and a set screw 15 is provided on the rack 6. Through the fixed connection between the fixed jaw and the swing jaw, and the close combination with the shell, a strong and durable clamp body structure is provided, which can withstand repeated use and rough operation. The stroke of the device is adjustable and can be adjusted according to the ear thickness of different animals. It can not only improve the accuracy of the ear tag clamp's pressing stroke, but also reduce the ear injury of livestock during marking, thereby avoiding stress response of livestock due to pain during marking and ensuring the personal safety of staff.

[0030] In addition, the reducer 10 is connected to the motor 11, the motor 11 is connected to the battery 12, the first rotating shaft 13 connects the motor 11 and the reducer 10, the trigger 3 is mechanically connected to the first control panel 7, the fixed jaw 1 and the swing jaw 2 are vertically arranged, the reducer 10 is arranged between the housing 4 and the motor 11, the fixed jaw 1 and the swing jaw 2 are made of metal alloy, and through the cooperation of the battery, the motor and the reducer, the electric ear tag pliers can automatically complete the clamping and installation of the ear tag, which greatly reduces the work intensity of the user.

[0031] Working principle: The trigger 3 is mechanically connected to the first control board 7 to trigger the motor 11 to start. The motor 11 is fixedly connected to the battery 12 to provide a stable power supply. The rotational power of the motor 11 is transmitted to the reducer 10 through the first rotating shaft 13 to reduce the speed and increase the torque. The reducer 10 is fixed to the housing 4, and the opening and closing stroke of the swinging jaw 2 is accurately adjusted through the meshing of the gear 5 and the rack 6. The opening and closing of the swinging jaw 2 is accurately controlled by a Hall element controller. When the trigger triggers the motor to start, the gear 5 starts to rotate, and the rotation drives the rack 6. Because the rack 6 is connected to the swinging jaw 2, the ear tag clamp can be opened and closed. The distance between opening and closing is realized by the Hall element through magnetic induction. By changing the orientation of the magnet, the opening and closing stroke of the swinging jaw 2 of the ear tag clamp can be changed. This design reduces the labor intensity of the user and improves the accuracy and efficiency of ear tag installation.

[0032] An adjusting bolt is provided above the rack 6 of the swing jaw 2, and a set screw is provided on the side above the rack 6, which is used to tighten the adjusting bolt to prevent it from loosening during operation. A magnet is installed at the eccentric part of the end face of the adjusting bolt, and the orientation of the magnet can be changed by rotating the adjusting bolt. The magnet is used to sense the Hall element on the second control board 8, and the second control board 8 is equipped with two Hall elements A and B. When the magnet swings to the A Hall element position, the jaws stop opening, and when the magnet swings to the B Hall element position, the jaws stop closing. The orientation of the magnet is changed by rotating the adjusting bolt, so that the opening and closing of the swing jaw 2 can be adjusted to achieve precise marking.
