The present disclosure provides a glue-saving mechanism, a glue gun handle, a glue gun and a use method thereof, and relates to the technical field of gluing tools, wherein the glue-saving mechanism is applicable to the glue gun and includes a body and a locking piece; a top end of the locking piece is connected with a rear end of the body, the locking piece is provided with a assembling hole for glue gun ejector rod penetrating the locking piece, and the angle between a front surface of the locking piece and the horizontal direction is greater than 0 and smaller than 90 when a length extension direction of a glue gun ejector rod in a working condition that the glue gun ejector rod is assembled to the glue gun is regarded as a horizontal direction; a guiding structure is provided on the body, and the guiding structure is used for guiding the body to slide forward and backward relative to a glue gun handle in a working condition that the glue-saving mechanism is assembled at a top end of the glue gun handle; and the glue gun handle is mounted with the glue-saving mechanism, and the glue gun has the glue gun handle. The present disclosure has the advantageous effect of controlling the glue to stop outflowing when the glue gun stops gluing so as to save glue.

A dispenser assembly includes a rod, a plunger and a stopper. The rod has a plunger receiving end with a clip receiving recess. The plunger has a rod receiving structure with a rod engaging clip biased to fit to the clip receiving recess of the rod for movement therewith. The stopper has a plunger receiving space that defines an aperture extending through the plunger receiving space with the rod extending through the aperture. The plunger receiving space is dimensioned such that with the rod receiving structure of the plunger located within the plunger receiving space, movement of the rod engaging clip is restricted by contact with surfaces of the plunger receiving space preventing release of the rod from the plunger.

A hand held jacking/levelling-tool is provided comprising a jacking shaft and a frame moving relative to each other during jacking action, a caulking gun jacking mechanism providing the jacking action, two outer legs fastened to one of the frame and the jacking shaft and one middle leg fastened to the other of the frame and the jacking shaft being positioned between a left and right outer leg. Furthermore the jacking/levelling tool comprises a foot fastened at a right angle to each leg and pointing in the same direction. The jacking action causes the jacking shaft to move downward through the frame.

A dispenser for dispensing a viscous material contained in a flexible package has a hollow body extending along a longitudinal axis, a first end with a handle assembly, an opposite second end with a dispensing valve, and a cavity configured to receive the flexible package. A piston is movably disposed in the cavity for engagement with the flexible package to force viscous material from the flexible package. A diverter insert is also disposed in the cavity and is configured to receive the viscous material from the flexible package as the piston moves and divert the viscous material to the dispensing valve.

A caulking gun includes a push disk, a push rod, an adhesive cartridge compartment, a trigger and a gun body; the trigger is hingedly coupled to the middle part of the gun body; the rear end of the push rod is outside the gun body and provided with a braking device; the front end is in the adhesive cartridge compartment through the gun body and provided with a push disk; a push piece for driving the push rod is mounted in the gun body; the front end of the push piece is provided with a return spring; the trigger is provided with a pin position switching device for adjusting the propulsion ratio by adjusting the contact position of the push piece; adjustment of different propulsion ratios enables the caulking gun to be multifunctional to meet the construction requirements of different adhesives.

A dispenser for dispensing a viscous material contained in a flexible package includes a body extending along a longitudinal axis that has a first end, an opposite second end, a cavity configured to receive the flexible package, and a handle assembly coupled to the first end. The handle assembly has a fixed handle, a trigger pivotally coupled to the fixed handle, and a rod extending between the fixed handle and the trigger into the cavity. A plurality of dispensing valves are positioned at the second end of the body and configured to dispense the viscous material, and a piston is movably disposed in the cavity for engagement with the flexible package. As the trigger is pivoted toward the fixed handle, the rod moves along the longitudinal axis toward the piston such that the piston engages the flexible package and the viscous material dispenses through the plurality of dispensing valves.

The present technology is a material dispensing system for controllably dispensing material from a packaging such as a chub pack. The system can include a housing capable of receiving the packaging, at least one nozzle tip including at least one piercing projection capable of piercing the packaging, a piston rod, a motor, and a transmission assembly for converting torque from the motor to a translation output of the piston rod. A ring gear can be operably associated with a planetary gear of the transmission, with a lock block slidingly engageable with the ring gear to prevent it from rotating or to allow the ring gear to rotate freely. A trigger is utilized to control the motor and to operate the lock block.
