Specifically, push rod 1 and 4 sliding connection of gluey rifle shell, fixed grab handle 3 is located one side of push rod 1, and fix on gluey rifle shell 4, then user's one end is held on fixed grab handle 3, promote the packing element through the push rod 1 that is located fixed grab handle 3 top side, realize the action of current beating glue, furthermore, the one end of action pole 5 is articulated mutually with the articulated department of gluing rifle shell 4 last, it has ejector pad 7 to articulate on the action pole 5, connect on push rod 1 through ejector pad 7 one end, the other end is connected on action pole 5, when then having realized action pole 5 and swinging, drive ejector pad 7 and promote the purpose of push rod 1. The other end of action bars 5 is connected with activity grab handle 2 through connecting rod 6, activity grab handle 2 articulates on gluing gun shell 4, and all be located the same one side of push rod 1 with fixed grab handle 3, therefore, as shown in fig. 4,

action bars

5 and 6 looks pin joints of connecting rod form the power arm to

action bars

5 and 4 looks pin joints of gluey gun shell, as thick dotted line AC shows, the point that action bars 5 and ejector pad 1 are connected reaches

action bars

5 and 4 looks pin joints of gluey gun shell and form resistance arm, as thick dash-dot line AB shows, because the length of power arm is good at the length of resistance arm, consequently, the size of power is less than the size of resistance, thereby not only realized rotating activity grab handle 2 and driven action bars 5 and swung the mesh that thereby drive ejector pad 7, and realized carrying out laborsaving mesh through the lever principle of 5 different formation of stress point.

As shown in fig. 1 to 3, a guide post 42 is arranged inside the glue gun shell 4, the push rod 1 is slidably connected to the center of the guide post 42, and one end of the action rod 5 is hinged on the guide post 42.

Specifically, glue gun shell 4 inside and set up installation cavity 41, guide post 42 is located the inside wall of installation cavity 41, and activity grab handle 2 and fixed grab handle 3 all with guide post 42 on one side relative. In addition, a guide hole matched with the push rod 1 is formed in the guide column 42, and the push rod 1 is connected with the guide column 42 in a sliding mode through the guide hole, so that the push rod 1 can slide in a guiding mode through the guide hole. Furthermore, the symmetrical both sides of guide post 42 are equipped with articulated post 43, and the symmetrical both sides of one end wherein of action bars 5 are equipped with the hinge hole with two articulated posts 43 size looks adaptations, and action bars 5 pass through the hinge hole and articulate on articulated post 43.

As shown in fig. 2 and 3, the movable handle 2 is provided with a centering hinge hole 21 and a rotating hinge hole 22, the rotating hinge hole 22 is located at one end of the movable handle 2, and the rotating hinge hole 22 is located at one side of the centering hinge hole 21; the movable grab handle 2 is hinged on the glue gun shell 4 through a centering hinge hole 21, and the movable grab handle 2 is hinged with the connecting rod 6 through a rotating hinge hole 22.

Specifically, as shown in fig. 4, a resistance arm is formed between the centering hinge hole 21 and the rotating hinge hole 22, as shown by a thick dotted line DF, and taking any one of the force points at the position where the movable grip 2 contacts with the hand of the user as a point E, a power arm is formed between the centering hinge hole 21 and the force point E, as shown by a thick dotted line DE, because the length of the power arm is longer than that of the resistance arm, the magnitude of the power is smaller than that of the resistance, and the purpose of saving labor is further achieved by a lever principle that the force points of the movable grip 2 are formed differently.

As shown in fig. 3, the middle part of the action rod 5 is provided with a fixing groove 51 matched with the push block 7, the fixing groove 51 and the movable grab handle 2 are positioned at the same side of the action rod 5, and one end of the push block 7 is hinged on the fixing groove 51; the other end of the push block 7 is provided with a through hole 71 matched with the push rod 1, and the push block 7 is connected with the push rod 1 in a sliding mode through the through hole 71.

Specifically, the fixing groove 51 of the action lever 5 is located on the side facing the side where the glue cartridge is placed, that is, the side facing the side where the push rod 1 pushes the glue toward one end of the glue cartridge. Therefore, when the action rod 5 swings forwards, the pushing block 7 connected between the push rod 1 and the action rod 5 is driven to push forwards, and the purpose that the pushing block 7 pushes the push rod 1 is achieved.

As shown in fig. 1 to 3, the glue gun with labor-saving structure further comprises a spring 8 matched with the push rod 1; an installation cavity 41 is arranged in the glue gun shell 4, one end of a spring 8 is fixed on the inner side wall of the installation cavity 41, and the other end of the spring 8 is fixed on the push block 7.

Specifically, the spring 8 is threaded on the push rod 1, and therefore, when the push block 7 is pushed to push the push rod 1 forward by pressing the movable grip 2, the spring 8 is compressed at the same time. When the movable grab handle 2 is loosened, the spring 8 pushes the push block 7 to the original position under the action of elastic deformation recovery, so that the purpose of automatic reset of the movable grab handle 2 is realized, and the problem that a user resets the movable grab handle 2 by himself is solved.

As shown in figure 1, the glue gun with the labor-saving structure further comprises a stopping plate 9, a stopping hole 91 is formed in the stopping plate 9, the diameter of the stopping hole 91 is larger than that of the push rod 1, and one end, penetrating through the stopping hole 91 and the stopping plate 9, of the push rod 1 is hinged to the glue gun shell 4.

Specifically, when the push block 7 is pushed to the original position by the elastic deformation recovery of the spring 8, the push rod 1 is prevented from returning along with the action of the push block 7 by the action of the retaining hole 91.

As shown in fig. 2, the glue gun with labor-saving structure further comprises a retaining spring 10 matched with the push rod 1, wherein the push rod 1 penetrates through the retaining spring 10; one end of a retaining spring 10 is fixed on the glue gun shell 4, and the other end of the retaining spring 10 is fixed on a retaining plate 9.
