TECHNICAL FIELD

[0001] The utility model relates to the technical field of beak forceps, and particularly relates to beak forceps with an anti-static function. BACKGROUND

[0002] With the continuous development of modern science and technology, especially the rapid progress of electronic technology towards miniaturization and precision, the sensitivity of electronic components and devices is also increasing. In these environments sensitive to static electricity, the traditional beak forceps have exposed serious problems in use.

[0003] In the prior art, ordinary beak forceps are prone to generate static electricity during shearing, trimming and other operations due to the friction, extrusion and other interactions between the forceps body and the object being operated. Once the static electricity is generated, it will gradually accumulate on the forceps body. When the static electricity accumulates to a certain extent, static discharge may occur inadvertently. The energy released by this static discharge is extremely harmful to small and precise electronic components. SUMMARY

Thus, the torsion of the clockwork 52 is limited, the lead wire 55 is prevented from being retracted, and the operation convenience and comfort during the whole long-time operation are improved.

[0025] Working principle:

[0026] The plier body 1 is the main part of the oblique mouth pliers, which is used to perform cutting and other operation tasks. The sleeve ring 2 fixedly connected to the outer side of the plier body 1 is rotatably connected with the connecting handle 4 through the pin shaft 3. This connection mode enables the plier body 1 and the connecting handle 4 to relatively rotate, so as to realize the opening and closing action of the oblique mouth pliers and meet the normal use function. In the normal holding state, the compression spring 6 is in a certain compression state, which provides a certain holding elasticity for the user and increases the holding comfort. When the user releases the holding, the elastic recovery force of the compression spring 6 helps the whole holding part 5 to recover to the initial state, so as to prepare for the next holding and operation.

[0027] In use, the metal cover plate 58 is taken out from the hollow handle 51, and then the metal cover plate 58 is turned over, so that the metal hook 50 is located away from the lead wire 55.

The metal hook 50 is connected with external grounding facilities, so that the static electricity generated on the plier body 1 can be effectively conducted away, and the accumulation of static electricity on the plier body 1 is avoided.

[0028] In the process, when the wire 55 is pulled out from the hollow handle 51, the wire 55 is gradually released from the surface of the winding drum 54, and the winding drum 54 and the rotating shaft 53 are rotated, at this time the rotating of the rotating shaft 53 will generate a certain torsional force on the spring 52, so that the spring 52 is gradually tightened and stores elastic potential energy. When the operation is completed, the spring 52 will gradually restore to its original state under the action of its own elastic potential energy, drive the rotating shaft 53 to rotate in the opposite direction, and drive the wire 55 and the metal cover plate 58 to reset, so that the metal hook 50 is retracted into the hollow handle 51, at this time the magnetic attraction ring 57 can be attracted to the metal cover plate 58 by magnetic force and clamped on the surface of the hollow handle 51, thereby improving the convenience of use of the beak forceps.

[0029] When long-time operation is required, the knob 562 in the limiting component 56 is rotated, so that the threaded rod 563 is rotated, at this time the sliding plate 564 slides on the inner wall of the fixed shell 561, and the arc-shaped pressing plate 566 is pressed on the surface of the spring 52 through the connecting rod 565, thereby limiting the torsion of the spring 52 and preventing the wire 55 from being retracted, thereby improving the operation convenience and comfort during the entire long-time operation process.
