Problems solved by technology

[0003] However, the link mechanism composed of the link group and the trigger is limited by the swing range and position of the trigger, and the design and actuation track of the link are very limited. Most importantly, because the full link The actuation method of the mechanism is affected by the moving space and the direction of the applied force. Much of the force of pressing the trigger will be lost in the useless component force in the relative movement of the complicated connecting rods. To drive the push rod forward, a large force must be applied. power, more laborious
[0004] In addition, this kind of complicated connecting rod system is not only difficult to manufacture and assemble, but also easy to rotate or get stuck at the pivot joints between the connecting rods after a long time of use, which is really inconvenient

Embodiment Construction

[0029] The following examples illustrate possible implementations of the present invention, but are not intended to limit the protection scope of the present invention.

[0030] Please refer to Figure 1 to Figure 5 , The present invention provides a glue gun, which includes a body 10 , a push rod 20 , a push block 30 , a connecting rod set 40 , a trigger 50 and a limiting member 60 .

[0031] The main body 10 has a first end and a second end opposite to each other. The main body 10 includes an operating portion 11 extending downward near the second end to form a handle 12 . In this embodiment, the operation part 11 is in the shape of a side view, an opening is formed between the lower end of the operation part 11 near the first end and the upper end of the handle 12, and the operation part 11 is close to the first end. The lower end at one end is connected with the upper end of the handle 12 through a connecting piece 13 .

[0032] The push rod 20 passes through the operati...

Abstract

The invention provides a glue gun, which comprises a body, a push rod, a push block, a connecting rod group, a trigger and a limiting piece. A grip handle extends out of the body bottom end, the push block and the connecting rod group are located in the body, the limiting piece is located at the rear end of the body, the push rod passes through the limiting piece, the body and the push block, the connecting rod group includes two connecting rods that are arranged along the horizontal direction and form an angle, and one of the connecting rods abuts against the push block. The trigger is pivoted in the body, and one end abuts against a push wheel between the two connecting rods, when the trigger is pressed, the push wheel is pushed upward by the trigger, and then the connecting rod group pushes the push block forward, so that the push block inclines to locate the push rod and drive the push rod to move forward.

Description

technical field [0001] The invention relates to a glue applying device, in particular to a glue gun. Background technique [0002] The glue gun is used to push out the colloid in the glue cartridge in sections, and the known glue gun, such as the Chinese Taiwan patent M406469 or the US patent US 6,640,998, usually uses a push block to match the connecting rod group, and the connecting rod group is connected to the trigger. The trigger pushes the push block through the action of the connecting rod and then drives the push rod to move forward. The trigger is directly pivoted with one of the connecting rods in the connecting rod group, so that the pressing pivot of the trigger can drive the connecting rod group to move . [0003] However, the link mechanism composed of the link group and the trigger is limited by the swing range and position of the trigger, and the design and actuation track of the link are very limited. Most importantly, because the full link The actuation m...
