A plurality of guide grooves 3 are provided on the outer wall of the second seat body 2; a plurality of push rods 4 penetrate through the outer wall of the second seat body 2. Connecting blocks 5 are respectively fixedly provided at the lower ends of the push rods 4. A sealing assembly 6 for positioning the tubing is fixedly provided on the bottom surface of the connecting block 5, and the sealing assembly 6 is located inside the first seat body 1, which is convenient for pushing the sealing assembly 6 to move to fix the tubing; a linkage assembly 7 that is threadedly sleeved on the outer wall of the second seat body 2 and is used to simultaneously adjust the movement of the sealing assembly 6. The linkage assembly 7 includes a guide block 71 slidably disposed inside the guide groove 3, which can guide the guide block 71 to make the vertical up and down movement of the guide block 71 more stable. A fixing block 72 is fixedly provided at one end of the guide block 71. A chute 73 is provided on the bottom surface of the fixing block 72. A slider 74 is slidably disposed inside the chute 73, which can guide the slider 74 to make the horizontal movement of the slider 74 more stable. The lower end of the slider 74 is fixedly connected to the upper end of the push rod 4, which is convenient for driving the push rods 4 to move simultaneously.

[0029] As Figure 2 and Figure 3 shown, the sealing assembly 6 includes four slips 61, and the outer ring surface of the slips 61 is conical, which can be closely attached to the inner wall of the first seat body 1. Card slots 62 are respectively provided on the outer walls of the slips 61. A sealing ring 63 is sleeved inside the card slots 62, which is convenient for expanding the sealing ring 63, facilitating the installation or disassembly of the tubing. A first sealing block 64 is fixedly clamped on the outer wall of the sealing ring 63, which can eliminate the gap between the slips 61 during the mutual extrusion process and improve the sealing performance.

[0030] As Figure 1 、 Figure 2 and Figure 4 shown, the linkage assembly 7 further includes a threaded collar 75 threadedly sleeved on the outer wall of the second seat body 2, which is convenient for moving the threaded collar 75 vertically upward or downward. A guide groove 76 is provided on the bottom surface of the threaded collar 75. A guide block 77 is slidably disposed inside the guide groove 76, which can drive a plurality of guide blocks 77 to move simultaneously. The lower end of the guide block 77 is fixedly connected to the fixing block 72, which is convenient for driving the fixing block 72 to move vertically up and down simultaneously.

[0031] Furthermore, flanges 8 are respectively fixedly provided at the opposite ends of the first seat body 1 and the second seat body 2, which is convenient for fixedly installing the first seat body 1 and the second seat body 2 at the oil hole.

[0032] Secondly, a plurality of rivets 9 penetrate through the socket joint of the first seat body 1 and the second seat body 2, which can fix the first seat body 1 and the second seat body 2 and facilitate installation or removal.

[0033] Furthermore, a sealing sleeve 10 is provided at the penetration of the second body 2 and the push rod 4, which can improve the sealing performance between the push rod 4 and the second body 2.

[0034] In addition, second sealing blocks 11 are fixedly arranged on the inner ring surface of the slip 61 respectively, which is convenient for closely fitting with the oil pipe and improving the sealing degree.

[0035] The working principle of this embodiment is as follows: Use bolts to fixedly arrange the flange 8 on the first body 1 or the second body 2 at the oil hole, and then penetrate the oil pipe through the inside of the first body 1 and the second body 2. Subsequently, manually rotate the threaded collar 75. The threaded collar 75 is threadedly connected to the second body 2, so that the threaded collar 75 moves vertically downward. The threaded collar 75 drives the guide block 77 to move vertically downward through the guide groove 76. The guide block 77 drives the fixed block 72 to move vertically downward. The fixed block 72 drives the slider 74 to move vertically downward. While moving vertically downward, the slider 74 slides horizontally in the chute 73.

[0036] Further, during the process of the slider 74 moving vertically downward, it drives the push rod 4 to slide in the sealing sleeve 10 on the second body 2. The push rod 4 drives the slip 61 to move vertically downward relative to each other through the connecting block 5, so that the sealing ring 63 expanded inside the card slot 62 on the slip 61 is restored to closely adhere to the inner wall of the first body 1. It can drive multiple push rods 4 to move simultaneously, without the need for sequential adjustment, reducing the operation steps and time, facilitating the quick connection or disassembly of the oil pipe, and improving the efficiency of oil pipe connection.

[0037] Furthermore, during the process of the slip 61 moving vertically downward relative to each other, the first sealing blocks 64 are mutually extruded between them, eliminating the gap between the slips 61. The slip 61 simultaneously drives the second sealing blocks 11 to closely adhere to the inner wall of the oil pipe, which can eliminate the gap between them, thereby improving the sealing performance and making it more convenient to install or disassemble the pipeline, and more convenient to use.

[0038] The above specific embodiments are merely several alternative embodiments of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
