A lowering mechanism for a hand held jacking tool comprises a caulking gun jacking mechanism. The lowering mechanism comprises a lowering plate on top of the holding plate, a pushing lever connected with a hinge attachment to the lowering plate at a rear end, wherein the pushing lever is pivoting around a pivot structure connected to the lever or holding plate a distance backward from the hinge attachment, causing the lowering plate to grip the jacking shaft when the lever is pushed downwards and then, in turn, pushing the holding plate downwards and loosening it from the jacking shaft and moving it down along the jacking shaft a distance determined by the pivoting action of the lever. The lowering plate is held in place by a spring biasing the lowering plate towards the holding plate.

A resiliently deformable member for use in an apparatus for dispensing a viscous material from a container, such as an apparatus consisting of a container for holding the viscous material and a dispensing gun. The resiliently deformable member has a relaxed state and a compressed state. In use, the resiliently deformable member applies a force between the container and the dispensing gun to modulate the flow of the material from the container.

A glue gun, including: a main body with one end formed as an accommodation part for accommodating a glue cylinder; a fixed handle connected to another end of the main body; a movable handle pivotally connected to the fixed handle; a push rod with one end located in the accommodation part; a brake provided on the push rod; and a movable member provided on the main body, where the movable member is configured to lock the brake, so as to continuously apply a force on the glue cylinder, and release the brake to release the force applied by the brake on the glue cylinder.

A caulking gun for dispensing material includes a stock, a cartridge keep, a push rod longitudinally moveably mounted in the stock with one end having a plunger engaging a cartridge piston in the cartridge keep, a catch on the rod, a trigger coupled to the catch via an axle and pivoting about a pivot point, and a device for varying thrust output exerted on the rod when pressing the trigger for a given strength exerted on the trigger that allows axle displacement between at least first and second positions. The trigger has an upper part with a trigger bridge with two long holes. The thrust output varying device includes a ratio bridge element put over the trigger bridge and trigger and linked to the trigger bridge via the axle traversing the holes. By displacing the axle either between fixed values or continuously and the thrust output can be varied between fixed values or continuously.

A device for scraping caulk is adapted to be used with a caulk gun. The device includes a base plate having a central void and an elongated portion extending from the base plate along an axis perpendicular to the base plate. The device can be fitted between a caulk tube and a caulk gun to allow the application of caulk and the scraping/reshaping of the caulk in a single run. The device can include different replacement tips useful for different applications and different desired results.

Caulking systems and caulking system accessories are described herein.

A station for covering a bread roll half of a bread roll with a sauce in a preparation line of a fast food restaurant, comprising: a table by which a user standing at a front side can cover a bread roll half with sauce, a container comprising the sauce and arranged over the table at a working distance from the front side and from which an outlet nozzle oriented towards the table protrudes at a vertical distance from the table, so that the bread roll half which is to be covered with sauce can be placed on the table below the outlet nozzle, and a pressure actuator that can be actuated by the user and which is designed to dispense the sauce from the container onto the bread roll half when actuated by the user.

A reversible and reusable caulk dispenser for use with a caulk gun. The caulk dispenser has a tubular cartridge with a plunger inside the cartridge near a first open end of the cartridge and an end cap with a nozzle that can be attached at an open second end of the cartridge. A foil packet of caulk or sealant material is inserted in the cartridge of the dispenser. A closed end of the packet is positioned adjacent the plunger while an open end of the packet is at the end of the cartridge where the end cap is attached. The dispenser is used in a standard caulk gun and the caulk material expelled through the nozzle as the caulk gun is operated. When the packet is emptied the dispenser can be reused with a new packet inserted and the end cap attached now to the opposite end of the cartridge.

A cutter and a caulking gun having the same are provided. The cutter is configured to be connected to a caulking gun having a connecting member which is disposed on the caulking gun and includes a first assembling portion. The cutter includes a main body including a base and a cutting portion connected with the base, the cutting portion includes a cutting blade, and the base includes a second assembling portion configured to be detachably connected with the first assembling portion.

A caulking gun includes a carrier for carrying a caulk cartridge, an assembly for the carrier, a gun body and a push rod. The assembly is for disposing between the gun body and the carrier and includes a seat portion and a spacing portion. The seat portion includes a seat wall for being connected between the gun body and the carrier. The spacing portion includes at least one projection portion disposed on the seat wall for being abutted between the gun body and the carrier in a manner that the gun body and the carrier are rotatable relative to each other. The carrier is rotatably connected with the gun body through the assembly, and the carrier is slidable relative to the at least one projection portion. The push rod is movably connected to the gun body and disposed through the assembly, and extends into the carrier.
