[0029] See Figures 1 to 8 This utility model provides an adjustable glue gun, including a fixed handle 1, a push rod 2 movably inserted into the fixed handle 1, and a movable handle 3 hinged to the fixed handle 1. A nest 4 is movably fitted onto the push rod 2, and the outer surface of the nest 4 has a threaded portion 9. An adjustment knob 5 is threaded onto the threaded portion 9. Rotating the adjustment knob 5 causes the nest 4 to slide along the push rod 2 via the threaded portion 9. A push block 7 is also provided on the other side of the nest 4, and the push block 7 is fixedly fitted onto the push rod 2. Therefore, after the nest 4 slides, the push block 7 can push the push rod 2 to move as a whole. The movable handle 3 is used to push the push block 7 and the push rod 2 laterally, and the adjustment knob 5 is used to... Adjusting the position of the nest 4 and the push block 7 adjusts the movement distance of the push block 7. The push block 7 is used to push the push rod 2 to extend and retract. By adjusting the position of the push block 7, the pushing distance of the push block 7 to the push rod 2 can be adjusted. The fixed handle 1 is provided with a mounting groove 8, and the adjustment knob 5 is installed in the mounting groove 8. The movable handle 3 is provided with a connecting shaft 6, which abuts against the push block 7. The movable handle 3 is used to push the push block 7 and the push rod 2 to move laterally through the connecting shaft 6. The adjustment knob 5 is used to adjust the position of the push block 7, thereby adjusting the movement distance of the push block 7, which is to adjust the pushing distance of the push rod 2 to the end of the colloid tube, thus realizing the adjustment of the colloid extrusion amount.
[0030] In some embodiments, such as Figure 4As shown, one end of the fixed handle 1 is threadedly connected to a colloid frame 10, and the colloid frame 10 is provided with a sliding cavity 11. The external colloid tube is installed in the sliding cavity 11. The end of the push rod 2 is provided with a push plate 12, which is movably disposed in the sliding cavity 11. When in use, the push rod 2 drives the push plate 12 to push the colloid tube to be extruded.
[0031] In some embodiments, such as Figures 2-5 As shown, a return spring 14 is embedded in the connecting seat 13 of the colloid holder 10. A groove 15 is provided on the end face of the push block 7. The other end of the return spring 14 abuts against the groove 15. The return spring 14 pushes the push block 7 to reset through the groove 15. The lateral movement distance of the push block 7 is limited to the end face of the connecting seat 13. After adjustment by the knob 5, the return spring 14 pushes the push block 7, shortening its stroke and reducing the amount of colloid extruded by the handle 3 in a single operation. The push rod 2 passes through the nest 4 and has a handle 17 connected to its end. A locking piece 16 is provided between the hand 17 and the nest 4. The locking piece 16 is fitted on the push rod 2 and its hole diameter is larger than that of the push rod 2. One end of the nest 4 is provided with a limiting spring 18, which is fitted on the push rod 2. The other end of the limiting spring 18 pushes the locking piece 16 to flip and lock the push rod 2. After the locking piece 16 is offset to one side and flipped, its inner hole is stuck on the surface of the push rod 2, locking the push rod 2 so that it cannot slide automatically. The locking piece 16 can be moved to unlock it and pull out the push rod 2 so as to install the colloid tube into the sliding cavity 11.
[0032] In some embodiments, such as Figure 7 and Figure 8 As shown, cylindrical positioning seats 19 are provided on both sides of the mounting groove 8. The nest 4 passes through the positioning seat 19. A positioning block 20 is provided through the inner wall of the positioning seat 19. The side wall of the nest 4 is provided with a positioning groove 21 corresponding to the positioning block 20. After assembly, the positioning block 20 is inserted into the positioning groove 21. At this time, the nest 4 cannot rotate axially along the positioning seat 19. The positioning block 20 is set parallel to the push rod 2 and the nest 4. At this time, the nest can only move back and forth along the direction of the positioning block 20. The adjusting knob 5 drives the nest 4 to move through the internal thread. The positioning block 20 converts the rotational movement of the nest 4 into a transverse movement, thereby realizing the movement of the push block 7 to adjust the amount of glue dispensing.
[0033] This utility model provides an adjustable glue gun. By rotating the adjustment knob, the push block can be moved towards the glue tube, thereby adjusting the position of the push block. This allows for adjustment of the stroke of the push block each time the movable handle moves, controlling the amount of glue dispensed per squeeze. This makes it more convenient in actual use, preventing excessive glue dispensing and overflow. The knob adjustment operation is also convenient and quick.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
