[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0027] Example 1

[0028] Reference Figures 2 to 5 , which is the first embodiment of the present utility model, provides a sealing strip bending device, which includes a telescopic component 200, a limiting component 300 and a main body component 100. The three can cooperate to retract the gun head, so that the retractable gun head can easily reach both narrow spaces and deep areas.

[0029] The telescopic assembly 200 includes a telescopic part 201, including a telescopic rod 201a, a moving frame 201b, a rotating block 201c and a rotating rod 201d. The moving frame 201b is fixed to one end of the telescopic rod 201a, the rotating block 201c slides in the moving frame 201b, and the rotating rod 201d is hinged to one side of the rotating block 201c.

[0030] The telescopic rod 201a is hinged to one end of the gun head 102. When the length of the gun head 102 needs to be adjusted, the rotating rod 201d is rotated. The rotation of the rotating rod 201d can drive the rotating block 201c to rotate, so that the rotating block 201c slides in the moving frame 201b, driving the moving frame 201b to move, and the moving frame 201b will drive the telescopic rod 201a to move. The movement of the telescopic rod 201a can drive the gun head 102 to move, so that the gun head 102 can be extended and retracted in the heating air gun 101.

[0031] The limiting assembly 300 is arranged on the rotating rod 201d, and includes a limiting member 301, including a limiting strip 301a and a limiting frame 301b. The limiting strip 301a is arranged on the rotating rod 201d, and the limiting frame 301b is sleeved on the outside of the limiting strip 301a.

[0032] After the gun head 102 is moved to the specified position, in order to prevent the rotating rod 201d from rotating on its own, the limiting bar 301a is engaged with the limiting frame 301b, so that the rotating rod 201d can be limited to prevent the gun head 102 from moving on its own. When it is necessary to release the limit on the rotating rod 201d and move the gun head 102, the squeezing plate 302a is squeezed, and the squeezing plate 302a can drive the limiting bar 301a to separate from the limiting frame 301b, thereby releasing the limit on the rotating rod 201d, and then the rotating rod 201d can be rotated.

[0033] Example 2

[0034] Reference Figures 2 to 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0035] Specifically, the telescopic assembly 200 further includes a rotating member 202 disposed on a rotating rod 201d, and a rotating disk 202a is fixed to one end of the rotating rod 201d.

[0036] The rotation of the pressing plate 301c drives the rotating disk 202a to rotate, and the rotation of the rotating disk 202a drives the rotating rod 201d to rotate.

[0037] Specifically, a moving rod 202b is fixed on the top of the rotating disk 202a, a moving block 202c is fixed on the top of the moving rod 202b, and a limiting block 202d is provided on one side of the moving block 202c.

[0038] When the rotating disk 202a rotates, it drives the moving rod 202b to rotate. The rotation of the moving rod 202b drives the moving block 202c to rotate. The rotation of the moving block 202c squeezes the limit block 202d to make it move. When the moving block 202c moves to separate from the limit block 202d, the limit block 202d returns to its original position. In this way, the reciprocating rotating disk 202a can play a damping role when rotating. The damping effect prevents the rotation of the rotating disk 202a from being too flexible or too rapid, and the operator can more accurately control the rotation angle and speed when adjusting.

[0039] Specifically, a positioning frame 202e is sleeved on the outer side of the limiting block 202d, the positioning frame 202e and the limiting block 202d are movably connected, and a first spring 202f is provided in the limiting block 202d.

[0040] The positioning frame 202e is used to support the limit block 202d to prevent the limit block 202d from shifting. When the limit block 202d is squeezed, a pulling force can be applied to the first spring 202f. When the moving block 202c is separated from the limit block 202d, the rebound force of the first spring 202f can drive the limit block 202d to return to its original position.

[0041] Specifically, a support box 202g is sleeved on the outside of the positioning frame 202e, and the support box 202g is sleeved on the outside of the rotating rod 201d. The support box 202g and the rotating rod 201d are movably connected.

[0042] The support box 202g is fixed to one side of the heating gun 101. The support box 202g can support the rotating rod 201d to prevent the rotating rod 201d from deflecting.

[0043] Specifically, the limiting assembly 300 further includes a pressing member 302 disposed on the rotating disk 202a, and an extrusion plate 302a is fixed to one end of the limiting bar 301a.

[0044] There are two squeezing plates 302a, both of which are fixed to one end of the limiting strip 301a. The limiting strip 301a can be moved by pressing the squeezing plates 302a.

[0045] Specifically, a positioning block 302b is sleeved on the outer side of the extrusion plate 302a, and the positioning block 302b is movably connected to the extrusion plate 302a.

[0046] The positioning block 302b is fixed to one side of the rotating disk 202a. The positioning block 302b can support the extrusion plate 302a to prevent the extrusion plate 302a from deflecting when moving.

[0047] Example 3

[0048] Reference Figures 1 to 5, which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0049] Specifically, a limiting groove X corresponding to the limiting strip 301 a is formed on the limiting frame 301 b.

[0050] A return spring is fixed to one side of the extrusion plate 302a. When the extrusion plate 302a is squeezed, an extrusion force is applied to the return spring. At this time, the extrusion plate 302a can drive the limiting strip 301a to separate from the limiting slot X provided on the limiting frame 301b. When the extrusion plate 302a is released, the rebound force of the return spring can drive the extrusion plate 302a to return to its original position, so that the limiting strip 301a is engaged with the limiting slot X provided on the limiting frame 301b, thereby limiting the rotating disk 202a.

[0051] Specifically, it also includes a main body component 100, which is arranged on one side of the support box 202g, including a heating air gun 101 and a gun head 102. The heating air gun 101 is fixed on one side of the support box 202g, and the gun head 102 is located inside the heating air gun 101.

[0052] A positioning strip is fixed on the inner wall of the heating air gun 101 , and the gun head 102 slides on one side of the positioning strip. A heating chamber is fixed on one side of the gun head 102 for generating heat to be ejected from the gun head 102 , and the heating air gun 101 is used to support the gun head 102 .

[0053] Specifically, a handle 103 is fixed to the bottom of the heating gun 101 .

[0054] The provision of the handle 103 makes it convenient for the user to hold the heating air gun 101 .

[0055] When in use, when the gun head 102 needs to be retracted or extended, the squeezing plate 302a is squeezed, and the squeezing force can be applied to the return spring at this time, and the squeezing plate 302a can drive the limiting bar 301a to separate from the limiting groove X provided on the limiting frame 301b, thereby releasing the limit of the rotating disk 202a, and then the rotating disk 202a is rotated. When the rotating disk 202a rotates, it will drive the moving rod 202b to rotate, and the rotation of the moving rod 202b will drive the moving block 202c to rotate, and the rotation of the moving block 202c will The limit block 202d is squeezed to move it, and when the limit block 202d is squeezed, a pulling force can be applied to the first spring 202f. When the moving block 202c moves to separate from the limit block 202d, the rebound force of the first spring 202f can drive the limit block 202d to return to its original position. In this way, the reciprocating rotating disk 202a can play a damping role when rotating. The damping effect prevents the rotation of the rotating disk 202a from being too flexible or too rapid, and the operator can more accurately control the rotation angle and speed when adjusting.

[0056] When the rotating disk 202a rotates, it drives the rotating rod 201d to rotate. The rotation of the rotating rod 201d can drive the rotating block 201c to rotate, so that the rotating block 201c slides in the moving frame 201b, driving the moving frame 201b to move, and the moving frame 201b drives the telescopic rod 201a to move. The movement of the telescopic rod 201a can drive the gun head 102 to move, so that the gun head 102 can be extended and retracted in the heating air gun 101. After the gun head 102 is moved to the specified position, the extrusion plate 302a is released, and the rebound force of the return spring can drive the extrusion plate 302a to return to its original position, so that the limit bar 301a is engaged with the limit slot X provided on the limit frame 301b, thereby limiting the rotating disk 202a.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
