[0031] The sealant extrusion device can adjust the accommodation length of the semicircular base 2, can be adjusted for sealant barrels of different sizes, and is also convenient for placing the sealant barrel. Specifically, when the sealant barrel needs to be loaded, pull the movable front cover 1 forward to provide a longer installation space. After installation, the length space can be shortened by tightening the positioning nut 26, or the linear motor can be directly started to push the extrusion plate 19 to shorten the length space. When the sealant barrels of different lengths are required, the accommodation length of the semicircular base 2 can be adjusted by twisting the positioning nut 26. In order to prevent the glue from continuously overflowing after shutdown, the following control program is installed in the electronic control unit. When the forward button 10 is released, the linear motor automatically reverses a certain distance, for example, automatically reverses 2-3mm, so that no extrusion occurs between the extrusion plate 19 and the piston of the sealant barrel.

[0032] In this embodiment, the front parts of both sides of the semicircular base 2 are provided with insertion holes, and the rear end of the movable front cover 1 is provided with positioning rods 7 that can be inserted into the insertion holes. The matching of the insertion holes and the positioning rods 7 increases the connection strength between the movable front cover 1 and the semicircular base 2.

[0033] In this embodiment, the linear motor includes a motor body 21 and a screw sleeve disposed in the motor body 21 and driven to rotate; a screw rod 22 is spirally connected in the screw sleeve, a connecting seat 27 rotatably connected to the screw rod 22 is fixedly connected to the rear end of the extrusion plate 19, and a guide rod 20 is disposed on both sides of the screw rod 22 at the rear end of the extrusion plate 19, and the guide rod 20 penetrates the fixed rear cover 3 and is connected by a connecting rod 23. During the gluing operation, the forward button 10 is pressed, the motor body 21 drives the screw sleeve to rotate forward, and the screw rod 22 is driven to move forward under the guidance of the guide rod 20 to push the extrusion plate 19, and vice versa, the reverse button 11 is pressed to withdraw the extrusion plate 19.

[0034] In this embodiment, a removable rechargeable battery 4 is installed at the rear end of the fixed rear cover 3. Through such an arrangement, it is possible to provide fast battery life by replacing the removable rechargeable battery 4.

[0036] In this embodiment, a telescopic pull rod is provided at the lower end of the front handle 5, and a support pad 6 is provided at the lower end of the telescopic pull rod. Through such a setting, the length of the front handle 5 can be adjusted. When the front handle 5 is not in use, the telescopic pull rod can be pulled out and prevented from falling on the ground, so that the height of the head is higher than the height of the tail end, reducing glue overflow.

[0037] In this embodiment, vertical grooves are provided on the left and right sides of the U-shaped groove 28; a plug plate 16 capable of being inserted into the vertical groove is provided at the rear end of the extrusion nozzle 15, and the extrusion nozzle 15 is provided with a left-right symmetrical two-half structure; a limiting groove 25 is provided at the rear end of the movable front cover 1, an internal thread is provided on the inner wall of the rear end of the extrusion nozzle 15, and inner recesses 18 are provided on both sides of the semicircular base 2.

[0038] Through such a configuration, on the one hand, the limit groove 25 is used to limit the front end of the sealant barrel from lifting and slipping during the process of squeezing out the glue, and on the other hand, through the use of the detachable two-half structure of the extrusion nozzle 15, after the glue is applied, the extrusion nozzle 15 can be pulled out of the vertical groove, and the extrusion nozzle 15 can be opened and cleaned, so that the extrusion nozzle 15 can be reused and environmentally friendly. Since the extrusion nozzle 15 is installed first and then the sealant cylinder is installed, after the sealant cylinder is installed in place, the fingers can rotate the sealant cylinder body at the position of the inner recesses 18 on both sides to screw it into the internal thread of the extrusion nozzle 15.

[0039] In this embodiment, a U-shaped support block 17 is provided at the front side of the movable front cover 1; the two sides of the extrusion nozzle 15 are squeezed and engaged in the inner U-shaped surface of the U-shaped support block 17. With such a configuration, the left and right halves of the extrusion nozzle 15 can be squeezed and pressed by the side of the U-shaped support block 17.

[0040] In this embodiment, in order to further increase the connection stability between the two halves of the extrusion nozzle 15, one half of the extrusion nozzle 15 is provided with a convex strip 29 on the upper side and a groove on the lower side; the other half of the extrusion nozzle 15 is provided with a groove that can seal and engage the convex strip 29 on the upper side and a convex strip 29 that can seal and insert into the groove on the upper side. The surfaces of the convex strip 29 and the groove are both coated with a sealing coating.
