[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a gear-type adjustable grip force-saving glue gun, which has the following beneficial effects:

Compared to traditional glue guns, this significantly reduces the force required for operation, decreases user hand fatigue, and improves work efficiency. By adjusting the height of the locking block, one method achieves the concentric effect of traditional use; another method adjusts the height of the locking block, causing the spring and unlocking plate to exert force on the push rod, thus locking it and creating a backward retraction, solving the problem of glue overflow. This results in advantages such as effortless operation, flexible grip adjustment, improved glue application accuracy, and prevention of glue spillage. Attached Figure Description

[0026] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0027] According to an embodiment of the present invention, a gear-type adjustable grip distance labor-saving glue gun is provided.
[0028] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-6 As shown, a gear-type adjustable grip and labor-saving glue gun according to an embodiment of the present invention includes a glue gun body 1. The glue gun body 1 is provided with a glue gun handle 2, a push rod 3, a glue injection stroke adjustment rod 4, an unlocking plate 5, a rack and pinion slider 6, an adjustment ring 7, a trigger gear 8, a trigger 9, a locking block 10, and a glue cylinder 12. The push rod 3 passes through the unlocking plate 5, the adjustment ring 7, and the locking block 10, and extends into the glue cylinder 12. The glue injection stroke adjustment rod 4 is parallel to the push rod 3 above it. A spring is sleeved on the push rod 3. The spring limits the adjustment ring 7 and the unlocking plate 5 respectively. The two ends of the spring limit the adjustment ring 7 and the unlocking plate 5 respectively, ensuring the relative position and movement stability of the adjustment ring 7 and the unlocking plate 5 on the push rod 3. The glue injection stroke adjustment rod 4 is equipped with a limit block 41, which abuts against the adjustment ring 7. A fixing block 71 is located at the bottom of the adjustment ring 7 and is engaged within the rack and pinion slider 6. The trigger gear 8 meshes with the rack and pinion slider 6 and is fixedly mounted on the upper end of the trigger 9. The glue gun handle 2 intersects with the trigger 9. An anti-overflow glue adjustment knob 13 is located between the glue injection stroke adjustment rod 4 and the unlocking piece 5. The glue overflow is controlled by adjusting the anti-overflow glue adjustment knob 13.
[0029] In one embodiment, the rack and pinion slider 6 has a locking slot 61 inside that mates with the fixing block 71. This locking structure allows the adjusting ring 7 to move as the rack and pinion slider 6 moves. The movement of the rack and pinion slider 6 indirectly increases the lever principle, thereby achieving a labor-saving effect.
[0030] In one embodiment, the adjusting ring 7 is further provided with a connecting hole 72, which passes through the push rod 3, allowing the adjusting ring 7 to slide on the push rod 3.
[0031] In one embodiment, the limiting block 41 is threadedly connected to the stroke adjusting rod 4, and the distance of the limiting block 41 on the stroke adjusting rod 4 is controlled by the thread. The position of the limiting block 41 on the dispensing stroke adjusting rod 4 is controlled by rotating the limiting block 41, thereby precisely adjusting the dispensing stroke. The limiting block 41 abuts against the adjusting ring 7; by changing the position of the limiting block 41, the movement range of the adjusting ring 7 can be limited, thus achieving adjustment of the dispensing stroke.
[0032] In one embodiment, the unlocking piece 5 has a slot 51.
[0033] In one embodiment, the locking block 10 is provided with an adjustment groove 101 and a toggle buckle 102. The toggle buckle 102 is located above the adjustment groove 101. The adjustment groove 101 consists of two sets of slots for easy vertical adjustment. Adjusting the height of the locking block 10 achieves two effects: one is the traditional method when concentricity is achieved; the other is adjusting the height of the locking block 10 so that the spring, in conjunction with the unlocking piece 5, exerts force on the push rod 3, thereby locking the push rod 3 and causing a backward movement, thus solving the problem of adhesive overflow. The upper holes of the two sets of slots are loose, while the lower holes are locked.
[0034] In one embodiment, the upper part of the trigger gear 8 is provided with teeth that mesh with the rack of the rack slider 6, and the upper parts of the trigger gear 8 and the trigger 9 are provided with a connecting shaft and are connected to each other through the connecting shaft.
[0035] In one embodiment, the trigger 9 is located at the opposite end of the glue gun handle 2 and is provided with a bearing 91, which is connected to the glue gun body 1. The surface of the trigger 9 is provided with grip texture.
[0036] In one embodiment, a pusher plate is provided on the side of the rubber tube 12, and the pusher plate is connected to the spring by compression.
[0037] Working principle: Rotate the limiting block 41 on the glue injection stroke adjusting rod 4 to adjust the position of the limiting block 41, thereby determining the glue injection stroke. Pull the trigger 9, and the trigger 9 drives the trigger gear 8 to rotate. The trigger gear 8 meshes with the rack and pinion slider 6, driving the rack and pinion slider 6 to move. Since the fixing block 71 of the adjusting ring 7 is engaged in the rack and pinion slider 6, the rack and pinion slider 6 drives the adjusting ring 7 to move. The movement of the rack and pinion slider 6 indirectly realizes the lever principle, thereby achieving the effect of saving effort. The adjusting ring 7 pushes the push rod 3 forward through the spring. The push rod 3 pushes the glue in the glue cylinder 12 to be squeezed out. The locking block 10 is provided with an adjusting groove 101 and a toggle buckle 102. The toggle buckle 102 is located above the adjusting groove 101. The adjusting groove 101 consists of two sets of slots for easy up and down adjustment. By adjusting the height of the locking block 10, one method achieves the traditional effect when concentricity is formed. Another method adjusts the height of the locking block 10 so that the spring, in conjunction with the unlocking piece 5, exerts force on the push rod 3, thereby locking the push rod 3 and causing it to move backward, thus solving the problem of glue overflow.
