[0030] The ignition coil body 1 is provided with a terminal head 13 , the upper end of the terminal head 13 is provided with a movable lifting plate 14 , and the lower end of the lifting plate 14 is fixed with an anti-slip plate 15 .

[0031] In this embodiment, when the automobile ignition coil needs to be installed, the ignition coil body 1 is moved and placed in the corresponding installation groove on the engine cylinder head. The engine cylinder head is provided with a plurality of limiting grooves. When the ignition coil body 1 is placed, the plurality of limiting strips 2 are installed in the plurality of corresponding limiting grooves. The rotating shell 10 limits the ignition coil body 1 so that the rotating shell 10 is outside the engine cylinder head. The rotating shell 10 is rotated, and the rotating shell 10 drives the gear ring 12 to rotate. Since the gear ring 12 is meshed with the gear 11, the plurality of gears 11 rotate simultaneously, and the gear 11 drives the bidirectional screw 5 rotates, and two threaded areas in opposite directions are provided on the bidirectional lead screw 5, so that the two moving seats 6 move in adjacent directions, and the moving seat 6 drives the push plate 8 to rotate. The push plate 8 will push the limit plate 7 while rotating, and the limit plate 7 drives the fixed block 9 to move. A plurality of fixing grooves matching with the fixed block 9 are provided on the engine cylinder head, so that one end of the fixed block 9 is stuck in the fixing groove, thereby fixing the ignition coil body 1 to the mounting groove on the engine cylinder head. During the driving process of the automobile, since the fixing block 9 is stuck in the fixing groove, the entire ignition coil body 1 will not be loosened or fall off.

[0032] More specifically, by rotating the rotating shell 10, the plurality of fixing blocks 9 are extended, thereby fixing the entire ignition coil body 1 to the mounting groove on the engine cylinder head. When a line connection is required, the plug with the wire is inserted into the terminal head 13, and the lifting plate 14 moves downward, and the lifting plate 14 drives the anti-drop plate 15 to move downward, so that the anti-drop plate 15 moves to one side of the plug, thereby limiting the plug to prevent it from falling off.

[0033] See also Figure 1-5 As an implementation method for moving the anti-slip plate 15: a support plate 16 is fixedly disposed at the lower end of the wiring head 13, two sleeves 17 are fixedly disposed on the support plate 16, a movable plate 18 is movably disposed in each of the sleeves 17, a lifting rod 19 is fixedly disposed at the upper end of the movable plate 18, the upper end of the lifting rod 19 is fixedly connected to the lifting plate 14, a spring 20 is disposed between the movable plate 18 and the sleeve 17, the spring 20 is movably sleeved on the outside of the lifting rod 19, and a wire release groove 21 is provided on the anti-slip plate 15.

[0034] Specifically, the lifting plate 14 is pulled upward, and the lifting plate 14 drives the two lifting rods 19 to move upward, and the lifting rods 19 drive the movable plate 18 to move, and the spring 20 is compressed. At the same time, the lifting plate 14 drives the anti-slip plate 15 to move upward. At this time, the plug head can be connected with the wiring head 13, and then the lifting plate 14 is released. Under the action of the spring 20, the movable plate 18 drives the lifting rod 19 to move downward, and the lifting rod 19 drives the lifting plate 14 and the anti-slip plate 15 to move downward, so that the anti-slip plate 15 moves to one side of the plug head, thereby limiting the plug head, and the connecting line can be placed in the wire groove 21.

[0035] See also Figure 1-5 As an implementation method for fixing the rotating shell 10: two fixed cylinders 22 are symmetrically provided at the upper end of the rotating shell 10, and a rotating disk 23 is movably provided in each of the fixed cylinders 22. A straight groove 24 is provided at the upper end of the rotating disk 23, and a screw 25 is fixedly provided at the lower end of the rotating disk 23. The screw 25 is threadedly connected to the rotating shell 10, and a threaded hole 26 matching the screw 25 is provided on the rotating shell 10.

[0036] Specifically, when the rotating shell 10 completes its rotation, a flat-blade screwdriver is inserted from the insertion hole 27 into the fixing tube 22, and one end of the screwdriver is inserted into the flat-blade groove 24. The screwdriver is turned so that the screwdriver drives the rotating disk 23 to rotate, and the rotating disk 23 drives the screw rod 25 to rotate. Since the screw rod 25 is threadedly connected to the rotating shell 10 through the threaded hole 26, the screw rod 25 moves downward while rotating, and the screw rod 25 is threadedly connected to the engine cylinder head, thereby fixing the rotating shell 10 to the engine cylinder head.

[0037] In summary, when the overall equipment is in use:

[0038] When the entire automobile ignition coil needs to be installed, the ignition coil body 1 is moved and placed in the corresponding installation groove on the engine cylinder head. The engine cylinder head is provided with a plurality of limiting grooves. When the ignition coil body 1 is placed, a plurality of limiting strips 2 are installed in a plurality of corresponding limiting grooves. The rotating shell 10 limits the ignition coil body 1 so that the rotating shell 10 is outside the engine cylinder head. The rotating shell 10 is rotated, and the rotating shell 10 drives the gear ring 12 to rotate. Since the gear ring 12 is meshed and connected with the gear 11, the plurality of gears 11 rotate simultaneously, and the gear 11 drives the bidirectional screw 5 rotates, and two threaded areas in opposite directions are provided on the bidirectional lead screw 5, so that the two moving seats 6 move in adjacent directions, and the moving seat 6 drives the push plate 8 to rotate. The push plate 8 will push the limit plate 7 while rotating, and the limit plate 7 drives the fixed block 9 to move. A plurality of fixing grooves matching with the fixed block 9 are provided on the engine cylinder head, so that one end of the fixed block 9 is stuck in the fixing groove, thereby fixing the ignition coil body 1 to the mounting groove on the engine cylinder head. During the driving process of the automobile, since the fixing block 9 is stuck in the fixing groove, the entire ignition coil body 1 will not be loosened or fall off.

[0039] When the rotating shell 10 needs to be fixed, after the rotating shell 10 has completed its rotation, a flat-blade screwdriver is inserted from the insertion hole 27 into the fixing tube 22, and one end of the screwdriver is inserted into the flat-blade groove 24. The screwdriver is turned so that the screwdriver drives the rotating disk 23 to rotate, and the rotating disk 23 drives the screw rod 25 to rotate. Since the screw rod 25 is threadedly connected to the rotating shell 10 through the threaded hole 26, the screw rod 25 moves downward while rotating, and the screw rod 25 is threadedly connected to the engine cylinder head, thereby fixing the rotating shell 10 to the engine cylinder head.

[0040] When it is necessary to connect the line through the terminal head 13, the lifting plate 14 is pulled upward, and the lifting plate 14 drives the two lifting rods 19 to move upward, and the lifting rods 19 drive the movable plate 18 to move, the spring 20 is compressed, and the lifting plate 14 drives the anti-slip plate 15 to move upward. At this time, the wire plug can be connected to the terminal head 13, and then the lifting plate 14 is released. Under the action of the spring 20, the movable plate 18 drives the lifting rod 19 to move downward, and the lifting rod 19 drives the lifting plate 14 and the anti-slip plate 15 to move downward, so that the anti-slip plate 15 moves to one side of the wire plug, thereby limiting the wire plug, and the connecting line can be placed in the wire release groove 21.

[0041] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the utility model have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the utility model. The scope of the utility model is defined by the attached claims and their equivalents.
