BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The utility model is a schematic diagram of the structure of the combined hot melt adhesive stick. DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] like Figure 1 As shown, a combined hot melt glue stick includes a hot melt glue stick 3, a shell 1 and an end 2. The hot melt glue stick 3 is installed in the shell 1, and the end 2 is threadedly connected to the shell 1. A heating structure is arranged in the end 2 for heating and melting the hot melt glue stick 3 in the shell 1 to form a colloid, thereby achieving the requirements of bonding various products.

[0016] Specifically, the shell 1 is provided with a placement groove 11, a push rod structure 12, a cutting structure 13 and an internal thread 14. The hot melt glue stick 3 is placed in the placement groove 11, and the push rod structure 12 can be movably arranged in the placement groove 11. When the hot melt glue stick 3 melts under the action of the end 2, the push rod structure 13 pushes the hot melt glue stick 3 to move, thereby realizing the extrusion of the colloid. The cutting structure 13 is installed on the outer surface of the shell 1, and is close to the end 2. It is used to cut the hot melt glue stick 3 that has been melted and deformed and cannot be used next time, so as to facilitate the next use. The internal thread 14 is arranged on the placement groove 11, and is close to the end 2.

[0017] Specifically, the push rod structure 12 includes a push rod 122, a push rod operating handle 121 and a push block 123. The push rod operating handle 121 and the push block 123 are respectively installed at both ends of the push rod 122. The push block 123 is movably arranged in the placement groove 11, and is used to push the hot melt glue stick 3 to move. Pressing the push rod operating handle 121 causes the push rod 122 to drive the push block 123 to move, and the push block 123 pushes the hot melt glue stick 3 to move, thereby driving the melted colloid of the hot melt glue stick 3 to be squeezed out.

[0018] Specifically, the cutting structure 13 includes a cutting blade 135, a guide rod 133, a pressing block 132, a spring 134 and a mounting seat 131. The mounting seat 131 is fixed on the housing 1. The cutting blade 135 and the pressing block 132 are respectively installed at both ends of the guide rod 133. The spring 134 is inserted into the guide rod 133. When the hot melt glue stick 3 needs to be cut, the pressing block 132 is pressed to compress the spring 134, drive the guide rod 133 to move, and move the cutting blade 135, so as to cut the hot melt glue stick 3. After releasing the pressing block 132, the spring 134 is reset, driving the pressing block 132 and the cutting blade 135 to reset.

[0019] Specifically, the terminal 2 includes a shell 21 and a heating element 23. The shell 21 is provided with a discharge port 22 and an external thread 24. The heating element 23 is arranged around the discharge port 22. The heating element 23 is used to heat the hot melt glue stick 3 located in the terminal 2, and the formed colloid flows out from the discharge port 22. The shell 21 can be a metal with good thermal conductivity and low hardness, such as copper or aluminum. The heating element 23 can be an active metal oxide, and the active metal oxide can be calcium oxide. The outer surface of the shell 21 is provided with an external thread 24, and the external thread 24 is threadedly connected to the internal thread 14, so that the terminal 2 is assembled on the outer shell 1 to facilitate the replacement of the terminal 2.

[0020] The above-described embodiments are only preferred examples of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent application scope of the present invention should be included in the scope of the patent application of the present invention.
