[0002] A hot melt glue gun is a tool used to heat and melt hot melt glue strips or rods, and then apply or spray the melted glue onto the objects to be bonded through a nozzle. It is a common handheld hot melt glue tool widely used in household, handicraft and industrial fields. However, some of the existing high-performance hot melt glue guns do not have good heat insulation, which may not only affect the service life of the hot melt glue gun shell, but also may scald the user. Therefore, technicians in this field have provided a heat-insulating high-performance hot melt glue gun to solve the problems raised in the above background technique. Content of the Utility Model

[0003] The purpose of the utility model is to provide a heat-insulating high-performance hot melt glue gun to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] A heat-insulating high-performance hot melt glue gun includes a hot melt glue gun body; a glue rod melting cavity is arranged in the middle of the interior of the hot melt glue gun body, and several PTC thermosensitive elements are arranged at the left end of the outer side of the glue rod melting cavity. A PTC thermosensitive element fixing frame is arranged in the middle of the lower side of the PTC thermosensitive elements; inner clamping blocks are arranged at the lower middle parts of the front and rear sides of the PTC thermosensitive element fixing frame, an inner clamping block clamping groove is arranged in the middle of the outer surface of the inner clamping block, and a fixing block is arranged in the middle of the interior of the inner clamping block clamping groove; several VRM heat dissipation fins are arranged at the left ends of the front and rear inner surfaces of the hot melt glue gun body; a glue rod socket is arranged in the middle of the right surface of the hot melt glue gun body, and a glue rod is arranged in the middle of the interior of the glue rod socket; an anti-scalding sheath is arranged in the middle of the left side of the hot melt glue gun body, and a glue outlet is arranged in the middle of the left side of the anti-scalding sheath; a non-slip grip for the hot melt glue gun body is arranged at the right end of the lower side of the hot melt glue gun body, a glue outlet trigger is arranged at the upper left end of the non-slip grip for the hot melt glue gun body, and a lithium battery is arranged in the middle of the interior of the non-slip grip for the hot melt glue gun body. The lithium battery is electrically connected to the PTC thermosensitive elements; lithium battery pressing plates are arranged on the left and right sides in the middle of the interior of the non-slip grip for the hot melt glue gun body, several telescopic springs are arranged at the upper and lower ends of the left side of the lithium battery pressing plates, and several lithium battery pressing plate sliding grooves are arranged on the upper and lower sides of the lithium battery pressing plates; several bracket rotating shaft fixing blocks are arranged at the left end of the lower side of the hot melt glue gun body, a bracket rotating shaft is arranged in the middle of the front surface of the bracket rotating shaft fixing blocks, and a bracket is arranged at the front end of the outer side of the bracket rotating shaft.

[0006] Preferably, on the left and right sides in the middle of the interior of the anti-slip grip of the hot glue gun body, there are lithium battery backing plates. At the upper and lower ends on the left side of the lithium battery backing plates, there are a number of telescopic springs, and on the upper and lower sides of the lithium battery backing plates, there are a number of lithium battery backing plate sliding grooves; at the left end of the lower side of the hot glue gun body, there are a number of bracket rotating shaft fixing blocks.

[0007] Compared with the prior art, the beneficial effects of the present utility model are:

[0008] 1. First, insert the glue stick into the interior of the glue stick hot melting cavity through the glue stick socket, then start the PTC thermistor by the lithium battery and preheat it. Then, the PTC thermistor will heat the glue stick inside the glue stick hot melting cavity. As the temperature of the PTC thermistor rises, the glue stick inside the glue stick hot melting cavity will be melted. Then, press the glue discharging trigger with a finger, and the melted glue stick will be discharged through the glue outlet. And there is a heat insulation sheath on the outer side of the glue outlet, which can thus play a good heat insulation effect on the glue outlet, avoiding the situation that the user is scalded by high temperature. And the PTC thermistor is installed on the PTC thermistor fixing frame, which can not only avoid the situation that the high temperature affects the service life of the outer shell of the hot glue gun body due to the direct contact between the PTC thermistor and the inner surface of the hot glue gun body during the working process, but also can well avoid the situation that the user is scalded due to a large amount of heat gathering on the inner surface of the hot glue gun body. And the VRM heat dissipation fins can also absorb the heat gathering on the inner surface of the hot glue gun body, thereby further improving the heat insulation and safety of the hot glue gun body. When it is necessary to replace the PTC thermistor, at this time, directly press the fixing block until the fixing block is completely separated from the inner block card slot, and then the PTC thermistor fixing frame can be removed, and then the PTC thermistor on the PTC thermistor fixing frame can be replaced, and further, the heating power of the hot glue gun body can be adjusted, thereby improving the practicability of the device; the PTC thermistor is installed on the PTC thermistor fixing frame, which can not only avoid the situation that the high temperature affects the service life of the outer shell of the hot glue gun body due to the direct contact between the PTC thermistor and the inner surface of the hot glue gun body during the working process, but also can well avoid the situation that the user is scalded due to a large amount of heat gathering on the inner surface of the hot glue gun body, and further improve the heat insulation and safety of the hot glue gun body.

[0009] 2. After the hot glue gun body is used up, at this time, the bracket can be rotated through the bracket rotating shaft until the bracket is rotated to the vertical state, and then the hot glue gun body is horizontally placed through the anti-slip grip of the hot glue gun body and the bracket, thereby avoiding the situation that the melted glue flows back due to the wrong placement of the hot glue gun body.
