Technical Field

[0001] This invention relates to the field of assistive feeding equipment technology, specifically a multifunctional feeding device for resting tremor motor dysfunction. Background Technology

At the same time, most existing assistive utensils are single-function (only spoons or forks), requiring frequent replacement, resulting in low eating efficiency. Furthermore, they are not designed with a core structure for "tremor counteraction," failing to fundamentally solve the problem of eating stability for patients and thus limiting their applicability.

[0017] The inner side of the handheld ring 8 is covered with a soft pad to reduce finger friction. The upper end of the anti-vibration device 3, located inside the limiting ring 5, has two semicircles. The two semicircles are limited by rotating the outer shell of the limiting ring 5.

[0018] The clamping device 4 includes a connecting plate 401, a fixed round rod 402, and a first spring 403; the first spring 403 is movably connected to the inner surface of the handle 1 through the fixed round rod 402; one end of the first spring 403 is fixedly connected to the side surface of the connecting plate 401; and the other end of the first spring 403 is fixedly connected to the inner surface of the handle 1.

[0019] The first spring 403 is configured to provide a certain elastic force to the connecting plate 401 to facilitate manual clamping operations.

[0020] The limiting device 6 includes a clamping housing 601, a limiting pressure plate 602, a lifting rod 603, a sliding rod 604, a second spring 605, a torsion spring 606, a rotating disk 607, a limiting disk 608, and a limiting rod 609. Two limiting devices 6 are provided, with identical structures and symmetrically arranged. The clamping housing 601 is fixedly connected to the output end of the anti-vibration device 3 via an extension rod. The limiting pressure plate 602 is slidably connected to the inner surface of the clamping housing 601. The lower end of the sliding rod 604 is fixedly connected to the upper surface of the limiting pressure plate 602, and the upper end of the sliding rod 604 is slidably connected to the inner surface of the clamping housing 601. The second spring 605 is sleeved on the side surface of the sliding rod 604, with the lower end of the second spring 605 fixedly connected to the upper surface of the limiting pressure plate 602, and the upper end of the second spring 605 fixedly connected to the inside of the clamping housing 601. The top sidewall features a rotating disc 607 rotatably connected to the inner surface of a limiting pressure plate 602, with the upper end of the rotating disc 607 fixedly connected to the lower end of a limiting disc 608. A torsion spring 606 is sleeved on the inner sidewall surface of the rotating disc 607. The upper end of the torsion spring 606 is fixedly connected to the lower surface of the limiting disc 608, while the lower end of the torsion spring 606 is fixedly connected to the inner sidewall surface of the limiting pressure plate 602. A limiting protrusion is provided on the outer side of the limiting disc 608, and a limiting rod 609 is fixedly connected to the upper end of the limiting disc 608. The limiting disc 608 is movably connected to the inner surface of the lifting rod 603 via the limiting rod 609. Anti-slip rubber is provided on one and the lower side of the inclined surface of the limiting pressure plate 602, as well as on the inner wall of the clamping housing 601 corresponding to the inclined surface. A groove corresponding to the limiting protrusion is provided on the upper inner sidewall of the clamping housing 601 near the top.

[0021] The angled opening on the limiting pressure plate 602 at the outlet position allows the handpiece to be inserted and shaken up and down to insert it.

[0022] Working principle: Pulling the lifting rod 603 causes it to slide along the side wall of the limiting rod 609. The protrusions on both sides of the limiting rod 609 then drive the limiting disc 608 upwards. Simultaneously, the limiting disc 608 moves upwards, causing the limiting pressure plate 602 to move upwards. When the limiting disc 608 moves into the groove in the clamping housing 601 corresponding to the limiting protrusion on its side, the limiting protrusion moves into the groove via the torsion spring 606, limiting the limiting pressure plate 602. Then, the handheld part of the chopstick 7 is placed in the two sections of the clamping housing 601. Finally, the lifting rod 603 is moved downwards, engaging the slot inside the lifting rod 603. The limiting rod 609 is held and rotated, which in turn drives the limiting disc 608 to rotate, moving the limiting protrusion out of the groove. At the same time, the limiting pressure plate 602 moves downward under the action of the second spring 605. The inclined surface set on the side of the limiting pressure plate 602 near the inner space of the clamping housing 601 pushes one of the chopsticks 7 to the edge for limiting, while the other chopstick is squeezed into another clamping housing 601 for limiting. Then, the limiting ring 5 is rotated to release the limiting of the two antivibration devices 3. At the same time, the antivibration devices 3 are popped open by the first spring 403 through the connecting plate 401. Then, the hand grips the inside of the hand ring 8 to perform the clamping operation.

[0023] Example 2: This embodiment is based on Embodiment 1: Pull up the lifting rod 603 and insert the handle of the spoon or fork into the clamping housing 601. The two sections of the handle are located inside the two clamping housings 601 respectively, and are limited by the compression of the lower end of the limiting pressure plate 602. Furthermore, holes can be drilled in the handle of the spoon or fork, and a protrusion can be provided at the corresponding position at the lower end of the limiting pressure plate 602 to further limit the handle and prevent it from falling off.

[0024] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
