The application discloses a body structure and a printer. The body structure comprises a casing and a printing assembly. The mounting cavity of the casing has a first bottom wall surface and a support surface arranged at intervals in the thickness direction of the body. The printing assembly comprises a print head located in the mounting cavity. The lower edge of the printing area is located between the first bottom wall surface and the support surface or is lower than the first bottom wall surface. The consumable box can be supported on the support surface, and the bottom surface thereof is located between the support surface and the first bottom wall surface or is flush with the support surface. That is, part of the consumable box is accommodated in the space between the support surface and the first bottom wall surface, so that the body structure can be adapted to consumable boxes with different thickness sizes, and the versatility of the body structure is improved. The body structure of the application also ensures that the printing paper is always located in the printing area in the thickness direction of the body, avoids offset printing or empty printing, and guarantees the printing quality.

This utility model discloses a nail gun missing nail reminder and anti-dry-firing structure, relating to the field of electric nail guns. It includes a nail clip installed on the nail gun housing near the nozzle, for inserting nails, with the clip opening communicating with a punch guide; a slider protruding from the nail clip and slidably mounted along its length, with a nail pusher plate installed at the slider head extending into the nail clip, the pusher plate head forked to form a connecting rod actuating end and a nail pushing end. When the slider slides along the nail clip, the pusher end contacts and pushes the nail into the punch guide for the punch to strike; a control board installed inside the nail gun housing, electrically connected to an anti-dry-firing switch; and an anti-dry-firing connecting rod, one end of which is the switch actuating end, and the other end of the nail pusher plate actuating end. This utility model prevents the nail gun from working when there are no nails in the nail clip or approximately 5 nails remain, reminding the user to accurately insert nails into the clip and into the correct positions before the nail gun can continue operating.

The utility model discloses an anti-empty nailing gun which comprises a clip, a gun nozzle and a nail feeding assembly, the clip comprises a first elastic plate and a second elastic plate, the first elastic plate and the second elastic plate form a through groove for the nail feeding assembly to move, the gun nozzle is provided with a safety plate in a sliding mode, and one end, close to the gun nozzle, of the second elastic plate is provided with a limiting plate in a rotating mode. One end of the limiting plate movably abuts against the nail feeding assembly, and the other end of the limiting plate is movably matched with the limiting groove in the safety plate. The nail feeding assembly gradually ascends along with gradual nailing of the gun nails, when the nail feeding assembly abuts against the limiting plate, the limiting plate rotates and is clamped into the limiting groove, then the safety plate cannot retreat to be flush with the gun nozzle, a plate handle fails to be pulled, empty nailing is effectively prevented, and the service life of the nailing gun is prolonged.
