A lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.

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 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 jacking tool capable of achieving up-down fine adjustment is provided, and belongs to the technical field of jacking tools. The jacking tool includes a fixed portion and a lifting portion; the fixed portion includes a base and a guide rod arranged on the base; the lifting portion is provided with a lifting plate, a climbing mechanism, and an adjustment grip for controlling the climbing mechanism; the adjustment grip is pressed to actuate the climbing mechanism, to control the lifting portion and the lifting plate to move up along the guide rod; the lifting portion is further provided with a locking mechanism clamped to the guide rod; the locking mechanism restricts the lifting portion from moving down; the lifting plate is slidably arranged on the lifting portion.

There is provided a dispensing mechanism for a bottle or cartridge. The mechanism includes a lever actuation of which causes a plunger to slidably engage an inner sidewall of the bottle and travel in a first direction towards an outlet of the bottle to expulse fluent material therefrom. The mechanism includes a portion stop connected to a cap and positioned at a defined location along the path of travel of the lever. The distance traveled by the lever is limited by direct contact of a tooth of the lever with the portion stop, thereby limiting the distance traveled by the plunger to limit an expelled amount of the fluent material to a corresponding defined portion. The tooth, when actuated, subjects the portion stop to a load. The tooth is shaped to promote spreading out of the load so as to inhibit damage/wear to and/or deformation of the cap.

A dispensing gun with an onboard tool stowage system is provided and has a frame body that includes a handle housing and a cartridge frame portion extending from said handle housing. The cartridge frame portion is configured for receiving a cartridge of work material therein. The frame body further includes at least one retention structure that has at least one receiving post protruding from said frame body. The dispensing gun further includes at least one accessory tool configured for detachable coupling with said at least one receiving post when stowed thereon, and a drive mechanism that is operably coupled to said frame body. The drive mechanism includes a drive member which passes displaceably into the cartridge frame portion responsive to operation of a trigger operatively disposed in the handle housing.

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 lifting and lowering tool includes a foot configured to be supported on a surface, a bar extending therefrom, and a movable assembly including a housing, a movable platform shaped to support a load that extends from the housing, a lifting actuator configured to incrementally move the movable assembly along the bar away from the foot, a lowering actuator configured to incrementally move the movable assembly along the bar towards the foot, and a release actuator configured to disengage the movable assembly from the bar to allow free movement of the movable assembly along the bar. In embodiments, the movable assembly engages the bar through locking plates that extend through a flange of the movable assembly. In embodiments the release actuator is spaced from the lifting actuator and the lowering actuator to prevent inadvertent actuation of the release actuator. In embodiments a flange of the movable assembly surrounds the bar.
