Description

Technical Field

[0001] The present application relates to the technical field of stationery products, and more specifically to a coating transfer tool. Background Art

[0002] A film transfer tool, also known as correction tape or correction tape, is a tool that can transfer the film on a film tape to the surface of other objects. Its function is similar to correction fluid. It is applied to paper to cover typos and can be rewritten immediately, providing convenience for learning and work. The film transfer tool mainly includes a shell and a refill assembly installed inside the shell. Currently, the shell is divided into a one-piece shell and a split shell. The one-piece shell cannot be disassembled, so the refill assembly inside the shell cannot be replaced. The correction tape needs to be discarded together with the shell after use, which wastes a lot of resources. The first shell and the second shell of the split shell are generally detachably connected. The user can remove and replace the internal refill assembly by disassembling the first shell and the second shell. The first shell and the second shell are tightly fitted or snap-fitted through connecting columns and connecting holes. Not only is disassembly and assembly laborious and cumbersome, but the snaps also have a relatively short lifespan under long-term switching conditions. For example, the Chinese utility model patent with publication (announcement) number CN207373990U discloses a roll-up stationery, including a front shell, a functional device, an inner shell, a back cover and a cover plate. The functional device is assembled in the inner shell. The front shell has a chamber with an opening at the front end. The functional device and the inner shell are placed in the chamber of the front shell, so that the pressure head of the functional device extends from the opening and the inner shell portion remains outside. The cover plate is installed at the opening to block the pressure head. The back cover is installed at the rear end of the front shell, and the back cover can be buckled into the inner shell to fix the various components in the front shell and the back cover. Its characteristic is that a protruding downward hook is formed on the top side of the inner shell downward and backward, and a protruding upward hook is formed on the top side of the back cover downward and forward. The back cover is buckled on the inner shell and is fixed by the upward hook of the back cover. The rocker is fixed by hooking the downward hook of the inner shell; in this technical solution, a rocker is provided and an upward hook is formed on the free end of the rocker, and the fixed end of the rocker can be installed in the installation opening formed on the top side of the back cover, and the free end of the rocker is located in the back cover and extends forward, and the rocker and the upward hook are manufactured independently and assembled on the back cover through the installation opening, and the upward hook is separated from the downward hook of the inner shell by pressing the rocker, and the rocker is supported by the support rod to ensure that the upward hook has elasticity. The length of the rocker is limited, that is, its force arm is short, the required pressing force is large, and it is more laborious to use, and the rocker is also subjected to the supporting force of the support rod and the fixing force of the back cover while being subjected to the pressing force. The rocker is subjected to large force and is easy to break, and there are problems such as poor installation stability and short service life. Summary of the Invention

The refill assembly 2 is connected to the second shell 3 so that the second shell 3 is in a covered state. The refill assembly 2 is limited in the first shell 1. The second shell 3 is opened by rotating so that the refill assembly 2 can be taken out from the first shell 1, so that the refill assembly 2 can be replaced after use or damage, thereby improving utilization rate and reducing use cost.

[0028] The second shell 3 is connected to the inner and outer shells of the second shell 3, and the connecting member 4 is provided with a lock 41. The lock 41 is connected to the core replacement component 2 so that the second shell 3 is locked relative to the core replacement component 2. The lock 41 is separated from the core replacement component 2 by force so that the second shell 3 is unlocked relative to the core replacement component 2. By adding the connecting member 4 with the lock 41, the second shell 3 is connected to or separated from the core replacement component 2 through the lock 41 of the connecting member 4. When the lock 41 is connected to the core replacement component 2, the second shell 3 is locked relative to the core replacement component 2. The second shell 3 is in the closed state. When the lock 41 is disengaged from the replacement core assembly 2, the second shell 3 is rotated and unlocked relative to the replacement core assembly 2, and the second shell 3 is in a rotatable open state. The user can replace the replacement core assembly 2 by applying force to the lock 41. The connecting piece 4 is provided to be connected inside and outside the second shell 3.

On the other hand, the first opening 31 cooperates with the switch 43 to limit the connecting member 4 in the second shell 3, which can prevent the connecting member 4 from detaching from the second shell 3, and is more reliable to use. In actual use, the user only needs to press the switch 43 to unlock the second shell 3. The structure is simple and reliable, and the disassembly and assembly operation is labor-saving.
