[0043] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] like Figure 1 , Figure 2 and Figure 3As shown, the hot melter provided in the embodiment of the present application includes a gripping portion 100, a hot melt portion 200 and a folding bracket 300. The gripping portion 100 is used for a user to hold, and the gripping portion 100 has a first end and a second end, and the second end is convex to form a convex portion 110. The hot melt portion 200 is connected to the first end of the gripping portion 100, and the hot melt portion 200 is configured to hot melt the plastic pipe to be connected.

[0046] The folding bracket 300 is rotatably connected to the protruding portion 110. The folding bracket 300 has a storage state and a supporting state. When the folding bracket 300 is in the storage state, the folding bracket 300 is buckled on the holding portion 100. When the folding bracket 300 is in the supporting state, the folding bracket 300 is rotated out from the holding portion 100. The folding bracket 300 cooperates with the second end of the holding portion 100 to support the hot melter. That is to say, when the folding bracket 300 is in the storage state, the folding bracket 300 is buckled on the holding part 100, and the user can directly hold the holding part 100 and the folding bracket 300 to weld the plastic pipes to be connected. This state is suitable for the situation that the user needs to hold the hot melter to weld the pipes, for example, welding the pipes at a high place. On the other hand, the folding bracket 300 is directly rotated and buckled on the holding part 100, so that the hot melter is stored as a whole. There is no problem that the folding bracket 300 is easily lost due to the separate storage, or the hot melter requires a large storage space and is stored unchanged. In addition, the overall volume of the hot melter can be reduced for easy storage. When the folding bracket 300 is in the supporting state, the folding bracket 300 is rotated out from the holding portion 100. At this time, the second ends of the folding bracket 300 and the holding portion 100 are respectively placed on the ground. The folding bracket 300 and the second end of the holding portion 100 cooperate to support the hot melter, so that the hot melter can be placed on the ground, and the length direction of the hot melt portion 200 is tilted upward. In this state, the user's hand holding the hot melter can be freed, which is convenient for user operation.

[0047] like Figure 3 and Figure 4 As shown, in some embodiments of the present application, the folding bracket 300 includes a first side 310 and a second side 320, the first side 310 and the second side 320 cooperate to form an L-shaped structure, the first side 310 and the second side 320 are both U-shaped structures, the first side 310 and the second side 320 are smoothly transitioned, the first side 310 is buckled on the protrusion 110, and the second side 320 is buckled on the gripping portion 100. This arrangement enables the folding bracket 300 to be buckled on the lower part of the gripping portion 100 in the stored state, and wrapped in the lower part of the folding bracket 300. This arrangement can reduce the volume of the hot melter in the stored state of the folding bracket 300, so that the radial dimension of the gripping portion 100 is maintained at a dimension suitable for human body grasping, which is convenient for users to grasp the gripping portion 100 and increases the comfort of users when holding the gripping portion 100 for work.

[0048] like Figure 1 and Figure 2 As shown, the protrusion 110 and the grip 100 are provided with a receiving groove 130, and the receiving groove 130 is configured to receive the folding bracket 300. That is, when the folding bracket 300 is in the receiving state, the folding bracket 300 is rotated into the receiving groove 130. This arrangement enables the folding bracket 300 to be engaged with the lower part of the grip 100 when it is rotated to be buckled, so that the radial dimension of the grip 100 is maintained at a dimension suitable for human grasping, which is convenient for the user to grasp the grip 100 and increases the comfort of the user when holding the grip 100 to work.

[0049] like Figure 3 As shown, in order to increase the comfort of the user holding the grip 100 , when the folding bracket 300 is in the storage state, the outer side surface of the edge of the folding bracket 300 close to the storage groove 130 is flush with the edge of the grip 100 and the protrusion 110 close to the storage groove 130 .

[0050] For example, in order to ensure that the folding bracket 300 can be stably placed in the storage slot 130 in the storage state and prevent the folding bracket 300 from shaking or rotating out of the storage slot 130 at will, a first clamping portion is provided in the storage slot 130, and a second clamping portion is provided on the folding bracket 300. The second clamping portion cooperates with the first clamping portion to clamp the folding bracket 300 in the storage state in the storage slot 130. Of course, the folding bracket 300 can also be fixed in the storage slot 130 by magnetic attraction or other methods.

[0051] like Figure 5 As shown, the end of the protrusion 110 away from the gripping portion 100 is provided with an installation site for the folding bracket 300, and a limiting notch is provided at the installation site, and the wall surface in the limiting notch facing away from the hot melt portion 200 is a limiting surface 111. Figure 4 As shown, one end of the first side 310 away from the second side 320 is rotatably connected to the installation site, and one end of the first side 310 away from the second side 320 has a limiting matching surface 330, and the limiting matching surface 330 cooperates with the limiting surface 111 to limit the folding bracket 300 from continuing to rotate. That is, in the supporting state of the folding bracket 300, the folding bracket 300 rotates out from the storage slot 130, and at the end of the rotation of the folding bracket 300, the limiting matching surface 330 is attached to the limiting surface 111, and the limiting surface 111 prevents the folding bracket 300 from continuing to rotate, so that the folding bracket 300 can be stably placed on the ground and cooperate with the support foot 120 to support the hot melt. Exemplarily, when the end of the rotation of the folding bracket 300, that is, the limiting surface 111 prevents the folding bracket 300 from continuing to rotate, the lower surface of the folding bracket 300 and the lower surface of the support foot 120 are located in the same plane, so that the folding bracket 300 and the support foot 120 can better cooperate to support the hot melt.

[0052] In some embodiments of the present application, Figure 1 As shown, in order to make the hot melt more stable when placed on the ground, a support foot 120 is provided at the first end of the gripping portion 100, and the support foot 120 extends to at least one side of the gripping portion 100 to form a foot-stepping position 121, and the foot-stepping position 121 is configured for the user to step on. When the folding bracket 300 is in the supporting state, the folding bracket 300 cooperates with the support foot 120 to support the hot melt. That is, when the folding bracket 300 is in the supporting state, the folding bracket 300 and the support foot 120 are respectively placed on the ground to support the hot melt, and when the user is in use, the user steps on the foot-stepping position 121, so that the hot melt is more stable when placed on the ground, and the hot melt is prevented from shifting or tilting when in use.

[0053] Exemplarily, the supporting feet 120 extend to both sides of the gripping portion 100 to form foot positions 121. This arrangement is convenient for users to use. Users can step on the foot position 121 with their left foot or with their right foot according to their needs.

[0054] In some embodiments of the present application, Figure 2 and Figure 5 As shown, in order to increase the stability of the support foot 120 and reduce its sliding, the side of the support foot 120 facing the ground is provided with anti-slip grooves 122.

[0055] Exemplarily, the support leg 120 is a circular structure, and the anti-slip pattern 122 is a plurality of arc grooves or arc protrusions arranged around the center of the support leg 120. This arrangement can increase the overall aesthetics of the hot melter.

[0056] like Figure 5 As shown, in some embodiments of the present application, the hot melt section 200 includes a hot melt plate 210 and a plurality of hot melt die sets, each of which includes a first hot melt die set 220 and a second hot melt die set 230 that match each other, and each hot melt die set is applicable to different sizes of plastic pipes to be butted. In other words, each hot melt die set includes a first hot melt die set 220 and a second hot melt die set 230 that match each other, and the radial sizes of the first hot melt die set 220 and the second hot melt die set 230 are different. The first hot melt die set 220 is used to heat the first pipe section, and the second hot melt die set 230 is used to heat the second pipe section that is butted with the first pipe section, and different hot melt die sets are applicable to hot melt butt-joining plastic pipes of different models and sizes.

[0057] In order to reduce the length of the hot melt plate 210, and then reduce the length of the hot melter as a whole, so as to make the hot melter more compact, a hot melt die head assembly installation site is provided on the hot melt plate 210, and any hot melt die head assembly can be detachably connected to the hot melt die head assembly installation site. In other words, the user can replace the hot melt die head assembly according to the needs to adapt to the hot melt butt joint of plastic pipes of different sizes. This setting enables the hot melter to be applicable to the hot melt butt joint of plastic pipes of different sizes on the basis of being compact, and has a wide range of applications.
