DETAIL DESCRIPTION OF THE INVENTION

(10) The present invention will be further described in detail combined with the figures and the embodiments.

Embodiment 1

(11) As shown in FIG. 1-5, glue extruding device 1 for aluminum tube of glue described in this embodiment is composed of a glue tube 2, a glue nozzle 3 and a cap 4 in glue extruding device 1. The tube in this embodiment is aluminum. Glue nozzle 3 is connected to the mouth 21 of glue tube 2 through screw thread. The cap 4 is covered on glue nozzle 3; Glue extruding device 1 adopts clamp tubular structure for lateral extrusion and with opening in front-end and back-end with the same length as glue tube 2. Glue extruding device 1 is integrally formed to be plastic whole piece, which consists of a base 11, two side plates and a retaining clip 15. The base 11 is planar rectangular structure, on which glue extruding device 1 can be placed vertically. In this embodiment, the base 11 adopts plate structure which is relatively simple. It is certain that grid structure can also be used or supporting foot, supporting bar or supporting block can be arranged on bottom surface of the plate; The two side plates are connected at the bottom to left side and right side of the base 11. Using this structure, aluminum tube can be placed vertically and stably, so that the glue in glue tube 2 will not contact with its mouth 21 or cap 4 to reduce the possibility that the mouth 21 is blocked by glue; In this embodiment, the two side plates can be extruded from one direction, one of the plates is a pressing plate 13, with extrudable elastic connection relying mainly on material elastic to the base 11, when it is necessary, the thickness at connection transition region 13c can be reduced to make pressing plate 13 be connected to the base and can be extruded inward through elastic deformation, another side plate is a fixed plate 12 with respect to pressing plate 13 to achieve fixation, in use, pressing plate 13 is pressed inward to extrude glue, pressing plate 13 is designed to realize the function to extrude all glue but do not need to completely squash glue tube 2, this is mainly because there is air in glue tube 2, residual air in the tube can squeeze out all the remaining glue without waste and user is not required to take out glue tube 2 and extrude glue with hands, and under substantially the same pressure, the amount of glue which is extruded is roughly the same; An inclined pressing surface 14 on inner wall of pressing plate 13 is formed to contact outer surface of glue tube 2 and facilitate glue extrusion. There is a matching surface 16 in the side of fixed plate 12, which is also inclined and composed of an inclined baffle in the side of fixed plate 12. Pressing surface 14 and matching surface 16 are smooth slope to make a full contact with outer wall of glue tube 2. The tilt angle is matched with glue tube 2. The inclined surface of fixed plate 12 is longer than the inclined surface of pressing plate 13 to increase contact area of glue extruding device 1 and glue tube 2 to the greatest extent. It is helpful to uniformly distribute extrusion strength and stably place glue tube 2; Retaining clip 15, with one end to connect to the top of fixed plate 12 and a circular through-hole 151 in the middle from which the mouth of glue tube 2 can extend out, is arranged above the base 11. The diameter of circular through-hole 151 is matched with outer diameter of glue nozzle 3. There is an accommodating cavity between the base 11, the two side plates and the retaining clip 15 to place and position the body of glue tube 2 to form clamp tubular structure with the same length as glue tube 2 for lateral extrusion and with opening in front-end and back-end. Glue extruding device 1 is integrally formed to be plastic whole piece. There is a port 151a in the front of circular through-hole 151 to insert the mouth 21 of glue tube 2. The width of port 151a is slightly less than outer diameter of glue nozzle 3. During installation, glue tube 2 is inserted from the side into the area between the side plates of glue extruding device 1, with the mouth 21 extending outside the retaining clip 15 and with threaded connection to glue nozzle 3 and mouth 21. Glue extruding device 1 covers all the body of glue tube 2, so that unexpected press or drop will not cause serious deformation or rupture of glue tube 2, with obvious protective effect; For ease of operation, there is stepped uneven texture structure 131 on outer side of pressing plate 13 for both slippage resistance and artistic appearance because pressing plate 13 is in contact with the fingers of user on the outside. In operation, place glue tube 2 with glue into the device, press its pressing plate 13 on the outside as usual and stop pressing after the amount of glue being extruded is enough. Remove glue tube 2 after the glue in it is used up and place a new glue tube in it for repeated use.

(12) The operation for the embodiment is simple and easy to understand. It takes only two seconds to place glue tube into this device. And users need no instruction to use this device well. It is very easy to use for gesture and method to extrude glue is exactly the same as ordinary use.

Embodiment 2

(13) As shown in FIG. 6-7, Embodiment 2 differs from Embodiment 1 in that side plates of glue extruding device 1 can be extruded from two directions. One of the plates is a pressing plate 13 with extrudable elastic connection to the base 11 and another is a fixed plate 12 with elastic connection in its side to another pressing plate 13a, pressing part 13b of pressing plate 13a is exposed through the opening 12a of fixed plate 12. One end of the retaining clip 15 is connected to upper end of fixed plate 12. Pressing surface of pressing plate 13 is inclined, with its tilt angle to match with outer surface of the tube. And the inclined surface of one side plate is longer than the inclined surface of the other side plate. During extrusion, both sides can be pressed inward to extrude glue. Other design is similar with Embodiment 1.
