The present invention provides a glue gun, comprising a movable handle and a fixed handle, wherein the movable handle is connected to fixed handle via a pivot pin shaft; the movable handle is further provided with an actuating member, and the actuating member is provided with an actuating part cooperating with a push member; and a spacing between the pivot pin shaft and the actuating part is sized to be switchable between two or more gears, such that the magnitude of the force applied by the actuating member on the push member is changed. The gear in the present invention can be adjusted to enable switching between a fast feed and a powerful feed, thereby enabling a user to make adjustment according to actual requirements.

An applicator is proposed comprising an outer sleeve having a cylindrical inner surface and a receiving space for a flowable substance to be applied and an inner sleeve which can be displaced in the outer sleeve and in which a frangible ampule containing the flowable substance is disposed and which has an opening connecting an interior of the inner sleeve to the receiving space of the outer sleeve and an activation means upon whose activation the ampule breaks.

An electrically powered handheld dispensing device used to dispense viscous materials from a cartridge in a drip-free manner. The dispensing device having a cartridge locking mechanism that affirmatively locks a material cartridge in place, limiting its axial motion in the cartridge holder. The dispensing device having a plunger assembly containing dogs that bite into the inner surface of the material cartridge piston after a plunger makes contact with the material cartridge piston. The dispensing device having a motor control circuit that automatically reverses the drive motor at high speed to reverse the piston inside the material cartridge to a predetermined distance when the user releases the trigger control, which may also suck material back from the cartridge nozzle tip preventing drips. A manually operated gear-release mechanism disengages the plunger assembly from the gear drive transmission, enabling rapid movement of the plunger in either direction for the loading or unloading of full or partially expended material cartridges.

Drug delivery devices and related methods of assembly are disclosed. The drug delivery device may include a main housing having an interior surface defining an enclosed space, and an exterior surface releasably attachable to a patient. A container may be disposed in the enclosed space and include a reservoir containing a drug and a stopper. A drive assembly may also be disposed in the enclosed space and configured to move the stopper through the reservoir to expel the drug from the reservoir. The drive assembly may include a rotational power source and a gear module. The gear module may include a mounting plate and a plurality of gears rotatably connected to the mounting plate. Furthermore, the mounting plate may be separate from the main housing.

A fluid dispenser assembly having a fluid reservoir (R), a dispenser member (5), and a dispenser orifice (62). The fluid reservoir (R) includes a piston (42) movable in leaktight sliding contact in a slide cylinder (41) over a maximum stroke between a start position that corresponds to a substantially full state of the reservoir, and an end position that corresponds to a substantially empty state of the reservoir. The dispenser assembly has a detector (35) arranged outside the fluid reservoir (R) and acts remotely to detect a determined physical property that enters into a small detection field that covers an alert position of the piston that is closer to the end position than to the start position. The piston (42) carries the detectable determined physical property and the detector (35) delivers, in response to a detection of the physical property, at least one alert signal perceptible to a user.

An improved system and method for loading paint continuously to a paintbrush. A substantially cylindrical container can comprise a first orifice, a second orifice, a void, a plunger, a rod, a biasing device, and a paint-dispenser. The first orifice at a front end of the container. The second orifice at a back end of the container. The void that can be within the container can be fillable with the paint. The rod can be slidably mounted within the second orifice and the ring. The biasing device can be positionable into expanded state, and extracted state. Further, wherein the biasing device can move relatively to the amount of paint that can placed within the void. The paint-dispenser can be connectable with the container through a hose, the paint dispenser can comprise a button. The button once actuated can be capable of releasing the paint to a paintbrush bristles.

A paint dispenser is described. In one embodiment, the paint dispenser can comprise a paint tube and a body. The paint tube can comprise an opening. The body can connect with the paint tube. The body can be capable of containing paint dispensable from the opening. Further, the body can comprise a pair of rail tracks, a pair of rack tracks, a pair of rails, a pair of racks, a pair of pinions, a pair of grips, a pair of axes, a pair of torsion spring, and a button. Each of the rails can be mounted within each of the rail tracks. Each of the racks can be mounted within each of the rack tracks. The pair of pinions can be at the center of middle layer of the body such that each of the pair of racks can come in contact with the outer edges of each pinion.

A glue gun, including: a main body, one end of the main body formed as an accommodation part for accommodating a glue cylinder; a first handle and a second handle, the first handle coupled to the second handle by a pivot pin shaft, one of the first handle and the second handle configured as a fixed handle, the other configured as a movable handle pivotable relative to the fixed handle, the fixed handle coupled to the other end of the main body, wherein the movable handle is provided with an actuating member, the actuating member configured to push a push member of the glue gun; at least one of the actuating member and the pivot pin shaft is configured to be adjustable in position to vary a distance between the actuating member and the pivot pin shaft, resulting in a switching between at least two gear positions.
