[0028] Example three: the bottom of the supporting part 52 is provided with protrusions on both sides, the protrusions being slidably installed in the first sliding groove 7.

[0029] The difference between the embodiment four and the embodiment one is that the driving handle 4 comprises the trigger 10, the pushing member 11 and the second elastic element 12, the driving handle 4 is rotationally connected with the mounting frame 3, the bottom of the pushing member 11 is rotationally connected with the top of the trigger 10, the second elastic element 12 is installed between the trigger 10 and the pushing member 11, the two ends of the second elastic element 12 abut against the trigger 10 and the pushing member 11 respectively, and the top of the pushing member 11 is in contact with the rack 9.

When the adjusting rod 14 slides to the rear end of the second sliding slot 13, the elastic element 6 normally works at this time, and the front and back movement of the clamping abutting plate 5 can be adjusted, and the front and back movement can realize the anti-dripping function of the glue gun; when the adjusting rod 14 slides to the front end of the second sliding slot 13, the spiral part 61 abuts against the glue pipe bracket 1, the connecting part 62 abuts against the supporting part 52 at this time, and the clamping abutting plate 5 cannot move forward, and the closing of the anti-dripping function of the glue gun is realized.

[0036] In the prior art, a self-locking plate is arranged behind the metal rod, and the metal rod is pulled back by the spring after the pushing is completed, so that the pressure in the rubber tube is released backward, thereby achieving the effect of preventing overflow of the glue. However, the reliability of the metal rod pulled by the static friction between metals is poor, and the phenomenon of unstable anti-overflow of the glue may occur after long-term use.

[0037] In summary, in the specific implementation, the extrusion push rod 2 is inserted through the rubber tube bracket 1, the bottom of the extrusion push rod 2 is provided with a rack 9, and the rack 9 is limited by the clamping abutting plate 5 arranged in the mounting rack 3 when moving in the mounting rack 3. The extrusion push rod 2 is inserted in the middle of the clamping abutting plate 5, and the bottom of the clamping abutting plate 5 is elastically supported by the elastic element 6 arranged thereon, so that the clamping abutting plate 5 can be clamped and abutted with the rack 9, thereby effectively preventing the extrusion push rod 2 from rebounding after being pushed forward, and the clamping abutting plate 5 can move forward along the first sliding groove 7 under the current condition. When the trigger 10 is released, the extrusion push rod 2 is driven during the backward movement of the pushing piece 11, the clamping abutting plate 5 is driven to retreat by the rack 9 of the extrusion push rod 2, and stops at the rear end of the first sliding groove 7, the rack 9 of the extrusion push rod 2 is engaged with the clamping abutting plate 5, and stops at the same time, thereby achieving the function of preventing dripping of the glue gun.

[0038] When the adjusting rod 14 moves to the front end of the second sliding groove 13, the elastic element 6 is driven forward by the adjusting rod 14 and makes the spiral part 61 abut against the rubber tube bracket 1, and the connecting part 62 abuts against the clamping abutting plate 5, so that the clamping abutting plate 5 cannot move in the first sliding groove 7, thereby achieving the simple switching of the functions of the glue gun without anti-dripping and anti-dripping.
