Description

Technical Field

[0001] The present application relates to the technical field of transfer tools, and more specifically to a coating film transfer device. Background Art

[0002] A coating transfer tool is a tool that can transfer the coating on a coating tape to the surface of other objects, such as correction tape. Existing coating transfer tools generally include a shell, a transfer head and a refill assembly. The refill assembly is equipped with a film tape for transfer. The coating on the film tape is transferred to the surface of other objects through the transfer head. In order to prevent the transfer head and part of the film tape from being exposed and getting dirty, the correction head and the film tape are currently protected by installing a protective cap on the transfer head. However, the protective cap needs to be repeatedly opened and closed in actual use, which is not only cumbersome to use but also easy to lose. Therefore, for example, the utility model patent with publication number: CN204567045U discloses a soft film push nozzle correction tape, including a shell, a correction tape body and a nozzle arranged in the shell; the correction tape body and the nozzle are jointly arranged on a sliding member, the shell is provided with a nozzle opening for the nozzle to be retracted, and the shell is also provided with an arc track, which extends to bypass the edge of the nozzle opening; a soft film is movably installed in the arc track, and the soft film has two connection points located on both sides of the center, one of which is connected to the sliding member, and the other connection point is connected to an operating part extending out of the shell for manual operation; in this technical solution, the nozzle structure is arranged on the shell in a retractable manner, and at this time, there is no need to provide a protective cap for protection, and by The belt body and the pressure nozzle are jointly arranged on a sliding member, and the sliding member drives the pressure nozzle and the correction belt body to extend out of the shell or retract into the shell by sliding. The back and forth sliding action of the sliding member is driven by the soft membrane, and the soft membrane is used to open and close the pressure nozzle opening to prevent the inside of the shell from being contaminated. However, when the correction tape is actually used, it is necessary to first push the operating part to move the soft membrane to open the pressure nozzle opening. After the soft membrane moves to abut against the sliding member, the sliding member is driven to slide, so that the pressure nozzle can extend out of the pressure nozzle opening. The sliding stroke of the operating part is long, and the soft membrane needs to be made long. Therefore, the driving force required for the soft membrane is large. The user needs to use a large force to push the operating part with a finger to make the soft membrane drive the sliding member to slide, and the entire stroke is relatively laborious. Utility Model Content
