[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] The utility model provides Figure 1-4 The electric heat shrink sleeve heating device shown in the figure comprises a hand-held handle 1, a power cord 4 is connected to the right end of the hand-held handle 1, and the power cord 4 is connected to the power supply through a plug 3 connected to the other end. A hinge connection 11 is arranged at the left end of the hand-held handle 1, and a heating fixture 2 with a variable angle is connected to the inner side of the hinge connection 11. A heating wire 13 is arranged inside the heating fixture 2, and a ceramic heat insulation layer 14 is arranged inside the heating fixture 2. At the left end, an upper fixed plate 10 and a lower fixed plate 8 are fixed at the upper and lower positions. A stainless steel bolt 5 is inserted and connected to the inner side of the upper fixed plate 10. A connecting rod 6 with an adjustable angle is installed at the inner side of the stainless steel bolt 5. A rotatable plate 7 is installed at the lower end of the connecting rod 6. The rotatable plate 7 and the bolt column 9 at the lower end can rotate. A threaded barrel 12 is fixed at the lower end of the lower fixed plate 8, and the rotatable plate 7 is sleeved at the inner position of the threaded barrel 12.

[0023] The use of the heating wire 13 for heating avoids the risk of explosion and fire that may be caused by the presence of open flames, greatly improving the safety of the workplace. The staff can easily control the heating work by holding the handle 1, and can accurately control the heating temperature and time to ensure the heating effect and quality of the heat shrinkable tape. Compared with traditional fire heating methods, heating with the heating wire 13 is more environmentally friendly, does not produce harmful gases and smoke, and is also more energy-efficient and can reduce energy consumption.

[0024] like Figure 2 and Figure 4 As shown, the hand-held handle 1 is installed with the heating fixture 2 through a hinge connection 11, and the power cord 4 is connected to the power supply through the plug 3. After the plug 3 is inserted into the power supply, the heating fixture 2 generates heat, and the heating fixture 2 generates a heat source through the electric heating wire 13 at the internal position. The heating fixture 2 is unfolded through the hinge connection 11 to adapt to heat shrink sleeves of different pipe diameters. The heating fixture 2 is tightly connected through the upper fixing plate 10 and the lower fixing plate 8. When the upper fixing plate 10 and the lower fixing plate 8 are fitted, they can be fixed by ordinary bolts. A through hole is provided at the upper end position of the upper fixing plate 10, and the stainless steel bolt 5 passes through the through hole of the upper fixing plate 10. The stainless steel bolt 5 is connected to the bolt column 9 through the connecting rod 6, and the angle between the stainless steel bolt 5 and the connecting rod 6 can be changed. A threaded barrel 12 is fixed at the lower end position of the lower fixing plate 8, and the bolt column 9 is connected to the threaded barrel 12 through the thread at the outer wall position.

[0025] When fixing the pipe diameter, the stainless steel bolt 5 and the bolt column 9 are inserted through the through hole in the upper fixing plate 10, and the bolt column 9 is rotated into the internal position of the threaded tube 12. At the same time, the rotation of the bolt column 9 and the rotatable plate 7 generate rotation. Since the pipe diameter wrapped inside the heating clamp 2 is too large, the heating clamp 2 is in an expanded state, which causes the angle between the stainless steel bolt 5 and the connecting rod 6 to change. When the bolt column 9 is rotated until the stainless steel bolt 5 fits the upper fixing plate 10, it can adapt to different pipe diameters.
