Description

Technical Field

[0001] The utility model relates to the technical field of glue guns, in particular to a soft and hard glue gun. Background Art

[0002] A silicone glue gun is a tool for applying glue (or squeezing glue). Silicone is widely used for sealing in construction projects, home decoration, electronic appliances, automobiles and auto parts, ships and containers and other industries. A silicone glue gun is a tool used for the construction and application of silicone or sealant. It is usually made of metal or plastic and has a trigger and a pressure rod to squeeze silicone or sealant out of the hose and apply it to the surface that needs to be sealed or filled. A silicone glue gun can help users precisely control the flow of glue and ensure that the glue is evenly applied to the surface that needs to be treated.

[0003] Traditionally, there are two types of glue guns, one is a glue gun specially used for hard-branch silicone bottles, and the other is a glue gun specially used for soft-branch silicone bottles. As the soft-branch glue gun has a longer soft silicone packaging, all glue gun barrels are also longer, which makes it inconvenient to apply glue in some places with small construction space. Hard-branch packaging of the same weight is more expensive than soft-branch packaging, and the price is high. The material used is mostly plastic bottles, which is not environmentally friendly. At the same time, whether it is a hard-branch or a soft-branch glue gun, most of the glue gun pull rod handles are bent at the end of the pull rod as a handle, which is not convenient to use.

At the same time, it can be freely disassembled and assembled according to construction needs, and can also be used for gluing construction of hard-branch silicone bottles. It has the advantages of flexibility, convenience, and free switching. It solves the problem that it is inconvenient to glue in some places with narrow construction space, hard-branch packaging of the same weight is more expensive than soft-branch packaging, and the material used is mostly plastic bottles, which is not environmentally friendly. At the same time, traditional glue guns, whether they are used for hard or soft branches, have a handle shape of the glue gun pull rod, and most of them bend the tail of the pull rod as a handle, which is not convenient to use.

[0007] Furthermore, a handle is fixedly connected to the lower end of the glue gun body, a through hole is provided in the middle of the glue gun body, and a through hole is provided on the side wall of the through hole.

[0008] Furthermore, a fixing seat is fixedly connected to the outer side of the glue gun body, and a pull rod lock is movably connected to the inner side of the fixing seat. The pull rod lock is arc-shaped, and a movable hole is opened on the surface of the pull rod lock. A fixing spring is fixedly connected between the pull rod lock and the glue gun body.

[0009] Furthermore, an annular thread groove is formed at one end of the glue gun body away from the pull rod lock, and the diameter of the annular thread groove is larger than the diameter of the through hole.

[0010] Furthermore, the pull rod is located on the inner side of the through hole, the right end of the pull rod is fixedly connected with a pull rod handle, and the left end of the pull rod is provided with a connecting groove, which is located in the middle position of the pull rod.

[0011] Furthermore, the circular iron sheet and the plastic propulsion sheet are threadedly connected to the connection groove via fixing bolts, and the diameter of the plastic propulsion sheet is greater than the diameter of the circular iron sheet.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
