[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and 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.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1 , which is the first embodiment of the present invention, provides an elbow head extraction device, which can realize the rapid extraction of the elbow head, and comprises a manipulation component 100, including a hydraulic component 101, a support component 102 installed on the hydraulic component 101, a sliding component 103 installed on the support component 102, and a pulling component 104 installed on the hydraulic component 101; and,

[0031] The hoop component 200 is used to hoop the elbow head to prevent wear. It is installed on the control component 100 and includes a clamping component 201 installed on the pulling component 104 and a buckle component 202 installed on the clamping component 201.

[0032] In summary, through the combined use of the control component 100 and the hoop component 200, the quick extraction of the elbow head can be achieved. The process is easy and labor-saving, solving the problems that the traditional extraction method is laborious and prone to wear the silica gel protective layer on the outer surface of the elbow head.

[0033] Embodiment 2

[0034] Refer to Figures 1 to 4 , which is the second embodiment of the present invention. The difference from the first embodiment is that it further includes a control component 100. In the previous embodiment, the elbow head extraction device includes a control component 100, which includes a hydraulic component 101, a support component 102 installed on the hydraulic component 101, a sliding component 103 installed on the support component 102, and a pulling component 104 installed on the hydraulic component 101.

[0035] Furthermore, the hydraulic component 101 includes a hydraulic pump 101a, a handle 101b installed on the hydraulic pump 101a, and a push rod 101c telescopically connected to the hydraulic pump 101a. When the handle 101b is operated back and forth, the push rod 101c will be pushed forward to extend.

[0036] Furthermore, the support component 102 includes a top plate 102a fixedly connected to the end of the push rod 101c. The top plate 102a is in a "you" shape, a through hole 102b opened on the top plate 102a, three groups of connecting rods 102c fixedly connected to the top plate 102a, and a horseshoe ring 102d fixedly connected to the connecting rods 102c.

[0037] Furthermore, the sliding component 103 includes a sliding sleeve 103a slidably connected to the connecting rod 102c and a fixed frame 103b fixedly connected to the sliding sleeve 103a.

[0038] Furthermore, the pulling assembly 104 includes a fixing ring 104a fixedly connected to the hydraulic pump 101a, two groups of pull rods 104b fixedly connected to the fixing ring 104a, and a blocking member 104c arranged on the pull rod 104b, wherein the pull rod 104b passes through the through port 102b and is slidably connected thereto, and the pull rod 104b is fixedly connected to a fixing frame 103b, and the fixing frame 103b can play a specific role in limiting the two groups of pull rods 104b, so that the pull rods 104b will not move away from each other when a large pulling force is applied to them. When the handle 101b is pressed back and forth, the push rod 101c extends out and will drive the fixing ring 104a to retreat through the reaction force, thereby driving the pull rod 104b to move in the opposite direction away from the horseshoe ring 102d.

[0039] Furthermore, the blocking member 104c includes two sets of mounting grooves 104c-1 provided at the end of the pull rod 104b, a blocking rod 104c-2 rotatably connected to the mounting groove 104c-1, a transmission block 104c-3 fixedly connected to the blocking rod 104c-2, an inclined surface 104c-4 provided on the transmission block 104c-3, a slide groove 104c-5 provided on the pull rod 104b, a push-out block 104c-6 slidably connected to the slide groove 104c-5, and a push-out block 104c-6 fixedly provided on the push-out block

[0040] The elastic member 104c-7 between 104c-6 and the slide groove 104c-5, when not interfered by external force, the ejection block 104c-6 receives the thrust of the elastic member 104c-7, and pushes the blocking rod 104c-2 to an open state through the transmission block 104c-3, and when the blocking rod 104c-2 is tightened in the installation groove 104c-1, the curvature of the outer surface of the blocking rod 104c-2 will be consistent with the curvature of the outer side of the pull rod 104b.

[0041] During use, when the operating handle 101b is pressed back and forth, the push rod 101c will be extended due to the hydraulic pressure. Since the push rod 101c is fixedly connected to the top plate 102a, and the fixing ring 104a is fixedly connected to the hydraulic pump 101a, when the handle 101b is pressed back and forth, the extension of the push rod 101c will drive the fixing ring 104a to retreat through the reaction force, thereby driving the pull rod 104b to move in the opposite direction away from the horseshoe ring 102d.

[0042] In summary, the coordinated use of the hydraulic assembly 101, the support assembly 102, the sliding assembly 103 and the pulling assembly 104 can achieve the effect of pressing the handle 101b to drive the pull rod 104b to move away from the horseshoe ring 102d.

[0043] Example 3

[0044] Reference Figures 5-6, which is the third embodiment of the present invention, is different from the previous two embodiments in that it includes a clamp component 200, which is used to clamp the elbow head to prevent wear. The clamp component 200 is installed on the control component 100, and includes a clamping component 201 installed on the pulling component 104, and a buckle component 202 installed on the clamping component 201.

[0045] Furthermore, the clamping assembly 201 includes a right-angle clamp 201a arranged at the end of the pull rod 104b, two groups of fixed tubes 201b fixedly connected to the right-angle clamp 201a, a rotating tube 201c rotatably connected to the outside of the fixed tube 201b, and a locking ring 201d fixedly connected to the rotating tube 201c, that is, the locking ring 201d is rotatably connected to the fixed tube 201b through the rotating ring. Since the fixed tube 201b is a hollow tube, the pull rod 104b can pass through the center of the fixed tube 201b.

[0046] Furthermore, the buckle assembly 202 includes a buckle seat 202a fixedly connected to one of the sets of locking rings 201d, a mounting seat 202b fixedly connected to the other set of locking rings 201d, a paddle 202c rotatably connected to the mounting seat 202b, and a buckle 202d rotatably connected to the paddle 202c. When the two sets of locking rings 201d are closed, the paddle 202c can be operated to make the buckle 202d on the paddle 202c buckle with the buckle seat 202a, and then the paddle 202c can be pressed until it is flush with the mounting seat 202b to complete the fixation between the two sets of locking rings 201d.

[0047] When the elbow head needs to be pulled out during use, the right-angle clamp 201a can be placed on the inner side of the elbow head, and then the two sets of locking rings 201d can be operated to surround the upper part of the elbow head, and the buckle ring and the buckle seat 202a are fastened, and then the horseshoe ring 102d is placed above the elbow head so that the elbow head is located in the middle of the horseshoe ring 102d, and then the pull rod 104b can be operated to move toward the fixed tube 201b, so that the pull rod 104b passes through the fixed tube 201b. When the pull rod 104b passes through the fixed tube 201b, the blocking rod 104c-2 will automatically retract into the installation groove 104c-1 When passing through the fixed tube 201b, the transmission block 104c-3 on the blocking rod 104c-2 is pushed by the push block 104c-6 to open the blocking rod 104c-2. At this time, the handle 101b can be pressed. As the push rod 101c slowly extends, the reaction force of the extension of the push rod 101c will drive the fixed ring 104a to retreat, thereby driving the pull rod 104b to move in the opposite direction away from the horseshoe ring 102d. Under the action of the blocking rod 104c-2, the right-angle clamp 201a will be driven to move simultaneously with the pull rod 104b, so that the horseshoe ring 102d can be easily pulled out.

[0048] In summary, by using the clamping component 201 and the buckle component 202 in coordination, the surface of the elbow head can be protected during the process of pulling out the elbow head.
