A toothbrush capable of inhibiting damage of an oral cavity of a user that includes: a head section that has a bristle implanting surface on a front end side; a handle section that is disposed on a rear end side from the head section and has a handle section main body; and a neck section that is disposed between the bristle implanting surface and the handle section. The toothbrush has a deforming portion that is located on the rear end side from the bristle implanting surface and is deformed, while stress characteristics associated with bending due to an external force acting on the head section are in a plane stress condition.

A cleaning device is provided that includes a handle, a cleaning implement, a flexible neck, and a collar. The cleaning implement depends from one end the handle. The flexible neck is positioned to allow flexion of the handle. The collar moves with respect to the flexible neck between a first position where movement of the flexible neck is unrestricted by the collar and a second position where movement of the flexible neck is restricted by the collar.

A cleaning wheel structure, which mainly comprises a cleaning unit, a universal joint and an elastic element, wherein the cleaning unit comprises a plurality of clamping jaws disposed around the circumference of the shaft thereof, and each of the clamping jaws has a positioning groove, the universal joint is disposed between the plurality of clamping jaws, the elastic element is disposed between the universal joint and the cleaning unit, wherein the outer surface of the universal joint is convexly provided with a positioning portion for embedding with the positioning grooves, with the above structure, when the cleaning unit is stuck and cannot be driven to rotate by the universal joint, the positioning portion repeatedly pushes each of clamping jaws outwardly to rotate and to be embedded in the next positioning groove, so that the universal joint no longer drives the cleaning unit.

A cleaning device is provided that has a handle configured to provide flexion in a first orientation but to provide rigidity in a second orientation. In this manner, the user can use the handle in the first orientation to allow the cleaning device to flex into hard to reach places and can use the same handle in the second orientation to apply differing levels of cleaning force.

The head of the toothbrush, rotating on its axis 180 degrees and 90 degrees to each side. A button is placed in the handle of the toothbrush with is connected to a lever, when the button is moved forward or backwards, it will apply force to the rotating pin. This is done by either using a gear system or simply attaching the lever to the side of the pin in order to transfer kinetic energy. The top of the rotating pin is attached to the part of the toothbrush that holds the bristles, which through rotating pushing or pulling the button can rotate the bristles 90 degrees each side or 180 degrees total. The bristle components can be composed of flexible material. This bristle part can be replaced or changed. Shorter, longer, wider, narrow, soft and harder bristle attachments can be used, based on the individual's needs.

A paint brush system, including a number of bristles held together inside the paint catch funnel and at also a bristles holder of the base providing a paint catch funnel circumferentially and about a lower enclosed area about each of the bristles, therein forming of the catch funnels of the base of the paint brush; whereas the paint catch funnel is connected to the upper part of the head, and between a bottom head and the top connector of the flex accordion-like neck, the neck is inserted and locked into the bottom head; at the bottom of the flex accordion-like neck, linearly repeatedly and extensively an element and also providing a transversely aspect of the flex accordion-like element and providing from an uppermost to a bottommost, and of the repeatedly element accordion ends; and further a threaded nonslip handle is provided at the end of the paint brush system.

A gun bore cleaner comprising a scrubber segment, a brush assembly segment and a cord segment. The central brush assembly is flexible or hinged so that it can bend and can be inserted into the narrow breech of a firearm without partial disassembly of the firearm. There is a brush integral to the brush assembly and bristles emanating from the scrubber assembly. The scrubber assembly, brush assembly and cord are separable for cleaning and substitution for bristle and brush diameter to be compatible with varying bore dimensions.

A pet comb generally includes a comb plate and a handle. The comb plate is provided with a plurality of comb strips at its front surface and a base portion at its rear surface. The handle is constructed of a spring element, which is attached with a connection portion and an enlarged main grip portion at two opposite ends thereof, and a covering, which has a concave neck portion formed integrally with the spring element, such that the enlarged main grip portion abuts on a rear end of the concave neck portion. The connection portion of the handle is fixedly attached to the base portion of the comb plate, such that the handle is at a predetermined angle to the comb plate. As such, the comb plate together with the comb strips can be easily operated by the handle to groom a pet.
