A torsion spring 111 is connected between the top of the crowbar 110 and the mounting block 12.

[0034] When the computer is connected to an external device using a stabilizing device for connecting the computer to the external device, the connecting plug 1 can be inserted backward into the front of the connector 11 and docked together.

The movable card is clamped on the square hole, so that the card frame 16 can be clamped by the first clamping block 13, which can make the connection between the connecting plug 1 and the connector 11 more stable; when the computer needs to be disconnected from the external device, the movable block 14 can be manually moved backward, and the movable block 14 moves backward to drive the connecting frame 15 to move backward, and the connecting frame 15 moves backward to drive the magnetic block 17 to move backward, and the magnetic block 17 moves backward to drive the first clamping block 13 to move toward the inside of the mounting block 12 and reset through the rocker 19, and the first clamping block 13 is reset to its original position. One card block 13 will be disengaged from the square hole, so that the first card block 13 will no longer jam the card frame 16, and the magnetic block 17 will move backward to separate from the iron plate 161. After that, people can pull the connecting plug 1 forward from the connector 11, and the connecting plug 1 drives the card frame 16 to move forward and reset and separate from the pressure block 18.

[0035] Example 2: Based on Example 1, Figure 8-Figure 9As shown, it also includes a shell 2, a rear plug-in block 21, a front plug-in block 211, a rotating block 22, a tension spring 24 and a pulling assembly. The left and right sides of the connecting plug 1 and the left and right sides of the connecting head 11 are connected to the shell 2. The front lower part of the shell 2 connected to the connecting head 11 is fixedly connected to the rear plug-in block 21.

Block 22, the two rotating blocks 22 on the left are squeezed together, the two rotating blocks 22 on the right are squeezed together, the rear rotating block 22 and the front plug-in block 211 are squeezed together, and the front rotating block 22 and the rear plug-in block 21 are squeezed together. A tension spring 24 is connected between the rotating block 22 and the inside of the shell 2, and the shell 2 is provided with a pulling component for pulling the rotating block 22 to rotate; the pulling component includes a pull rope 23 and a pull block 25, and the pull rope 23 is connected to the side of the rotating block 22 away from the tension spring 24, and the pull rope 23 passes through the shell 2 respectively, and the pull rope 23 is connected to the side of the rotating block 22 away from the pull spring 24. The pull ropes 23 pass through the shell 2, and the pull rope 23 is connected to the pull block 25.

[0036] In order to enhance the stability of the connection between the connecting plug 1 and the connector 11, a rotating block 22 and other components are provided. When the connecting plug 1 moves backward, it drives the housing 2 and the front plug block 211 thereon to move backward. When the front plug block 211 is inserted into the upper inner part of the rear housing 2, the rear plug block 21 is also inserted into the lower part of the front inner housing 2, and the front plug block 211 squeezes the two rotating blocks 22 at the rear, and the rear plug block 21 squeezes the two rotating blocks 22 at the front, so that the rotating blocks 22 rotate, and the tension spring 24 is stretched. When the front plug block 211 is fully inserted into the upper part of the rear housing 2 and the rear plug block 21 is fully inserted into the lower part of the front housing 2, the front rotating block 22 and the rear rotating block 22 fit together. At this time, under the action of the tension spring 24, the rotating block 22 will be driven to rotate and reset, so that the left After the two rotating blocks 22 fit together, they are rotated to lock the two outer shells 2 on the left side with each other. After the two rotating blocks 22 fit together, they are rotated to lock the two outer shells 2 on the right side with each other. By locking the outer shells 2, the stability of the connection between the connecting plug 1 and the connecting head 11 can be enhanced. If the connecting plug 1 and the connecting head 11 need to be disconnected, the pull block 25 is held and the pull rope 23 is pulled. The pull rope 23 drives the rotating block 22 to rotate to the side away from the tension spring 24. The tension spring 24 is stretched, and the rotating block 22 can release the outer shell 2 after rotation. In this way, people can move the connecting plug 1 forward and reset it, thereby making the front plug block 211 move forward and reset it, and then release the pull block 25. Under the action of the tension spring 24, the rotating block 22 is driven to reverse and reset, and the pull rope 23 and the pull block 25 are driven to move and reset.

[0037] like Figure 10As shown, it also includes a guide block 3, a mounting frame 31 and a guide wheel 32. The left and right sides of the top and bottom of the connector 11 are connected to the guide blocks 3, and the left and right sides of the top and bottom of the connector 1 are connected to a group of mounting frames 31. Each group is provided with symmetrically arranged mounting frames 31. The guide block 3 is inserted between each group of mounting frames 31. Three guide wheels 32 are rotatably connected to the mounting frames 31. The guide wheels 32 and the guide blocks 3 are squeezed together.

[0038] When the connecting plug 1 moves backward, it will drive the mounting frame 31 and the guide wheel 32 to move backward. When the guide wheel 32 contacts the guide block 3, the guide wheel 32 will rotate. Under the action of the guide wheel 32, the resistance of the connecting plug 1 to move backward can be reduced, so that the connecting plug 1 can be more smoothly and quickly docked with the connector 11.

[0039] like Figure 11-12 As shown, it also includes a support plate frame 4, an elastic pressure ring 41 and an extrusion assembly. The connecting plug 1 and the connecting head 11 are both provided with a support plate frame 4. The structures on the side of the support plate frame 4 away from each other are all ring structures. The ring structures are respectively sleeved on the wires. The left and right sides of the support plate frame 4 are connected to elastic pressure rings 41 for pressing the wires. The support plate frame 4 is provided with an extrusion assembly for squeezing the elastic pressure ring 41; the extrusion assembly includes a screw rod 42, a wedge block 43, a handle 44 and a top block 45. The support plate The sides of the frames 4 that are away from each other are slidably connected with wedge blocks 43, and the left and right sides of the support plate frames 4 are slidably connected with top blocks 45, the top blocks 45 and the wedge blocks 43 are squeezed together, and the top blocks 45 and the elastic pressure rings 41 are squeezed together, and the sides of the support plate frames 4 that are away from each other are rotatably connected with screw rods 42, and the screw rods 42 and the wedge blocks 43 are threadedly connected. The ends of the screw rods 42 that are away from each other are fixed with rotating handles 44, and the screw rods 42 are driven to rotate by the rotating handles 44, and the screw rods 42 drive the wedge blocks 43 to move.

[0040] During the docking process of the connecting plug 1 and the connector 11, the wire is easily bent, and the bending of the wire is easy to cause the connecting plug 1 and the connector 11 to break and loosen, which will cause problems during the use of the computer. Therefore, an elastic pressure ring 41 is provided to reinforce the position of the wire. The turning handle 44 can be manually rotated. The rotation of the turning handle 44 drives the screw rod 42 to rotate. The rotation of the screw rod 42 drives the wedge block 43 to move toward the side close to each other. The wedge block 43 squeezes the top block 45 and drives the top block 45 to squeeze the elastic pressure ring 41. In this way, the elastic pressure ring 41 can clamp the wire, thereby strengthening the fixation of the wire. If there is no need to reinforce the wire, the turning handle 44 can be manually reversed. The turning handle 44 drives the screw rod 42 to reverse. The screw rod 42 drives the wedge block 43 to move toward the side away from each other to reset and release the top block 45. The elastic pressure ring 41 recovers and pushes the top block 45 to reset.

[0042] In order to enhance the stability of the connection between the connecting plug 1 and the connector, a second card block 54 and other components are provided. When the connecting plug 1 moves backward, it drives the support plate frame 4 and the slotted block 5 thereon to move backward. The slotted block 5 is inserted into the middle position of the rear support plate frame 4. After the connecting plug 1 and the connector 11 are docked, the magnetic block 17 moves forward to drive the piston rod to move upward. The piston rod discharges the gas into the expansion block 55 through the air guide pipe 53. The expansion block 55 automatically expands and pushes the second card block 54. The second card block 54 moves and snaps into The second clamping block 54 can clamp the groove of the grooved block 5, thereby improving the stability of the connection between the connecting plug 1 and the connector.
