[0032] Specifically, the locking member 201 includes a limiting block 201a and a fixing block 201b. The fixing block 201b is fixed to the top of the heating rod 104, and the limiting block 201a is arranged on the top of the fixing block 201b.

[0033] A limiting hole is set on the fixing block 201b, and the limiting block 201a is set in the limiting hole. After the heating rod 104 is placed in the locking nut 105, the limiting block 201a is engaged with the limiting hole on the fixing block 201b, so that the heating rod 104 can be fixed to prevent the heating rod 104 from falling off.

[0034] Specifically, the locking member 201 further includes a movable rod 201c and a pressing plate 201d. The movable rod 201c is fixed to the top of the limiting block 201a, and the pressing plate 201d is fixed to one end of the movable rod 201c.

[0035] When it is necessary to release the limit on the heating rod 104 and take the heating rod 104 out of the locking nut 105, the movable rod 201c is moved, and the movable rod 201c moves to drive the limit block 201a to separate from the limit hole on the fixed block 201b, so that the limit on the heating rod 104 can be released, and the heating rod 104 can be removed. The setting of the pressing plate 201d is convenient for the user to press the movable rod 201c.

[0036] Specifically, the locking member 201 further includes a movable disk 201e and a fixed plate 201f. The movable disk 201e is fixed to the bottom of the movable rod 201c.

[0037] When the movable rod 201c is moved, the movable disk 201e can be used to support the movable rod 201c to prevent it from shifting. There are two fixed plates 201f, both fixed on the top of the fixed block 201b. The fixed block 201b can be used to support the movable disk 201e to prevent it from shifting.

[0038] Specifically, the locking member 201 further includes a rotating column 201g and a torsion spring 201h. The rotating column 201g is fixed to one side of the movable disk 201e, and the torsion spring 201h is sleeved on the outer side of the rotating column 201g.

[0039] The rotating column 201g is plugged into one side of the fixed plate 201f, and the rotating column 201g is movably connected to the fixed plate 201f. One end of the torsion spring 201h is fixed to one side of the fixed plate 201f, and the other end is fixed to one end of the rotating column 201g. When the movable rod 201c is moved, the movable disk 201e can be driven to rotate. The rotation of the movable disk 201e drives the rotating column 201g to rotate. The rotation of the rotating column 201g can apply a torsional force to the torsion spring 201h, and the movable rod 201c can be moved. The movable rod 201c moves to drive the limit block 201a to separate from the limit hole on the fixed block 201b, so that the heating rod 104 can be released from the limit, and the heating rod 104 can be removed. After the heating rod 104 is installed in the locking nut 105, the movable rod 201c is loosened. At this time, the force of the rotation of the torsion spring 201h can drive the limit block 201a to re-engage with the limit hole on the fixed block 201b, so that the heating rod 104 can be limited again.

[0040] Specifically, the reset member 202 includes a reset plate 202a and a support frame 202b. The reset plate 202a is disposed at one end of the heating rod 104, and the support frame 202b is fixed to one side of the reset plate 202a.

[0041] After the heating rod 104 is installed in the locking nut 105, the reset plate 202a will be squeezed. When the heating rod 104 needs to be removed, the heating rod 104 can be moved by the rebound of the reset plate 202a, so that the heating rod 104 can be taken out. The support frame 202b is used to support the heating rod 104 on one side of the reset plate 202a to prevent the heating rod 104 from shifting.

[0042] Specifically, the reset member 202 also includes a first movable column 202c, a first support sleeve 202d and a spring 202e. The first movable column 202c is fixed to one side of the positioning plate 103, the first support sleeve 202d is sleeved on the outside of the first movable column 202c, the first support sleeve 202d and the first movable column 202c are movably connected, and the spring 202e is fixed to one end of the first movable column 202c.

[0043] After the heating rod 104 is installed in the locking nut 105, the reset plate 202a will be driven to move. The movement of the reset plate 202a can drive the first support sleeve 202d to move. The spring 202e is fixed to the inner wall of the first support sleeve 202d, and the first support sleeve 202d is fixed to one side of the reset plate 202a. When the first support sleeve 202d moves, an extrusion force can be applied to the spring 202e. When the heating rod 104 needs to be taken out, the first support sleeve 202d can be driven to move by the rebound force of the spring 202e. The movement of the first support sleeve 202d drives the reset plate 202a to move. The heating rod 104 can be ejected from the locking nut 105 by the movement of the reset plate 202a. The first movable column 202c is used to support the first support sleeve 202d to prevent the first support sleeve 202d from deflecting.

[0044] Example 3

[0045] Reference Figure 3 and Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0046] Specifically, the reset member 202 further includes a second movable column 202f and a second support sleeve 202g. The second movable column 202f is fixed to one side of the positioning plate 103. The second support sleeve 202g is sleeved on the outside of the second movable column 202f. The second support sleeve 202g is movably connected to the second movable column 202f.

[0047] When the reset plate 202a moves, the reset plate 202a will also drive the second support sleeve 202g to move. By moving the second support sleeve 202g on the second movable column 202f, one end of the reset plate 202a can be supported to prevent the reset plate 202a from shifting when moving. The setting of the second movable column 202f can support the second support sleeve 202g.

[0048] When in use, when the heating rod 104 needs to be installed in the locking nut 105, first press the pressing plate 201d. The movement of the pressing plate 201d can drive the movable rod 201c to move. When the movable rod 201c moves, the movable plate 201e can be driven to rotate. The rotation of the movable plate 201e drives the rotating column 201g to rotate. The rotation of the rotating column 201g can apply a torsional force to the torsion spring 201h. The movement of the movable rod 201c can drive the limit block 201a to move and lift it. Then, the heating rod 104 is installed in the locking nut 105. After the heating rod 104 is installed in the locking nut 105, the reset plate 202a will be driven to move. The movement of the reset plate 202a can drive the first support sleeve 202d to move. When the first support sleeve 202d moves, a squeezing force can be applied to the spring 202e. At this time, in order to prevent the spring from The rebound force of 202e drives the reset plate 202a to move, and the heating rod 104 needs to be limited. The pressing plate 201d is released, and the rotating force of the torsion spring 201h can drive the limit block 201a to engage with the limit hole on the fixed block 201b, so that the heating rod 104 can be limited, so that the installation of the heating rod 104 can be completed. When the heating rod 104 needs to be removed, the pressing plate 201d is first pressed, and the pressing plate 201d drives the movable rod 201c to move. The movement of the movable rod 201c drives the limit block 201a to separate from the limit hole on the fixed block 201b, so that the heating rod 104 can be released from the limit. Then, the reset plate 202a is driven to move by the rebound force of the spring 202e, and the movement of the reset plate 202a drives the heating rod 104 to move, so that the heating rod 104 can be taken out of the locking nut 105.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
