The heating tube body 101 and the mounting head body 102 are recorded in the prior art as "including a heating tube body, a mounting head is threadedly connected to one side of the heating tube body, a high-temperature resistant insulating layer is fixedly installed on one side of the interior of the heating tube body, a magnesium oxide rod is fixedly installed on one side of the high-temperature resistant insulating layer, and a heating wire is wound around the outer side of the magnesium oxide rod, a pair of conductive rods are installed through the interior of the high-temperature resistant insulating layer, and one side of the conductive rod is respectively welded to the two ends of the heating wire, and the other side of the conductive rod is respectively welded with a high-temperature resistant wire, the interior of the heating tube body is filled with insulating magnesium oxide, an extension rod is fixedly installed on one side of the mounting head, a tail stock is threadedly connected to one side of the extension rod, and a pair of connecting heads are embedded and installed on one side of the tail stock", and the pressing component 10 is pressed. 4 can drive the transmission rod 105 to move, and the movement of the transmission rod 105 can drive the two inclined rods 106 to rotate. When the angle between the two inclined rods 106 and the transmission rod 105 becomes smaller, the two transmission rods 105 drive the two sliders 107 to slide on the installation head body 102 and approach each other. When the angle between the two inclined rods 106 and the transmission rod 105 becomes larger, the two transmission rods 105 drive the two sliders 107 to slide on the installation head body 102 and move away from each other. The movement of the two inclined rods 106 can drive the two sliders 107 to slide on the installation head body 102. The sliding of the two sliders 107 can drive the two reinforcement plates 108 to fix the connection between the heating tube body 101 and the installation head body 102.

[0023] The connecting rod 115 is slidably connected to the mounting head body 102, penetrates the mounting head body 102, and is fixedly connected to the transmission rod 105.

The first spring 117 is fixedly connected to the pressing plate 116 and is fixedly connected to the mounting head body 102, and is located between the mounting head body 102 and the pressing plate 116. Pressing the pressing plate 116 can drive the connecting rod 115 to move toward the side close to the mounting head body 102, and the transmission rod 105 can be driven to move through the connecting rod 115. At the same time, the pressing plate 116 can be reset by the resilience of the first spring 117, and then the connecting rod 115 can be reset.

[0025] In addition, the limit block 111 is slidably connected to the mounting head and is located on a side of the mounting head body 102 close to the connecting rod 115. The second spring 112 is fixedly connected to the limit block 111 and the mounting head body 102 and is located between the limit block 111 and the mounting head body. The connecting rod 115 has a plurality of limit holes. The limit block 111 cooperates with the corresponding limit holes to limit the connecting rod 115.

The movement of the pull rod 113 can drive the limit block 111 to move away from the connecting rod 115, contacting the limit of the connecting rod 115.

[0027] When it is necessary to fix the connection between the heating tube body 101 and the mounting head body 102, the pressing plate 116 is released, and the resilience of the first spring 117 pushes the pressing plate 116 to drive the transmission rod 105 on the connecting rod 115 to move, and the transmission rod 105 drives the two inclined rods 106 to rotate.
