Specific embodiments

[0029] Now, the present utility model will be further described in detail with reference to the accompanying drawings.

[0030] Please refer to Figures 1-4 As shown, in this embodiment, a spark plug that is easy to install is provided, including a spark plug 1 and an installation cylinder 5. The bottom end of the spark plug 1 is inserted into the interior of the installation cylinder 5. An outer sleeve 3 is installed on the outer side below the spark plug 1. A tightening mechanism 2 is installed at the lower position on the outer side of the installation cylinder 5. Arc grooves 10 are installed at the positions around the interior of the installation cylinder 5. Insertion rods 6 are installed at the positions around the bottom end of the spark plug 1. The insertion rods 6 are slidably installed inside the slots.

[0031] An application in one aspect of this embodiment is as follows: When installing the spark plug 1, install the spark plug in the interior of the installation cylinder 5. At this time, insert the insertion rods 6 at the bottom end of the spark plug into the arc grooves 10 inside the installation cylinder 5. After inserting the bottom end and then rotating, remove the external force, and the tightening mechanism 2 will push the spark plug 1 upward, and the installation of the spark plug 1 can be completed. When disassembling, perform the above reverse operation, and the spark plug 1 can be quickly installed and removed.

[0032] In this embodiment, the tightening mechanism 2 is composed of a spring 8 and a top plate 12. The top plate 12 is slidably installed on the outer side of the installation cylinder 5. The upper end of the spring 8 is installed at the bottom end of the top plate 12, and the bottom end of the spring 8 is installed at the bottom position of the installation cylinder 5. When the tightening mechanism 2 is in use, the spring 8 drives the top plate 12 to push the spark plug 1 upward, so that the insertion rods 6 are stably installed inside the arc grooves 10.

[0033] In this embodiment, the spring 8 is set as a damping spring 8. The damping spring 8 used for the spring 8 can not move when not under external force or under relatively small external force, so that the tightening mechanism 2 can more stably fasten the spark plug 1.

[0034] In this embodiment, a protective sleeve 11 is arranged outside the spring 8. The protective sleeve 11 is pasted at the bottom end of the top plate 12 and the lower position of the installation cylinder 5 through an adhesive. The setting of the protective sleeve 11 is used to protect the spring 8 to prevent the spring 8 from being corroded after long-term use and affecting the service life of the spring 8.

[0035] In this embodiment, a rubber pad 7 is provided at the upper end of the top plate 12. The rubber pad 7 is pasted at the upper end of the top plate 12 through an adhesive. The texture of the rubber pad 7 is relatively soft. During installation, it can be compressed to fill the gap between the top plate 12 and the bottom end of the spark plug 1, making the installation of the spark plug 1 more stable.

[0036] In this embodiment, a wrench 4 is provided at the middle position of the spark plug 1. The wrench 4 and the spark plug 1 are integrally provided. The setting of the wrench 4 facilitates the staff to hold, thereby facilitating the rotation of the spark plug 1 and thus facilitating the installation of the spark plug 1.

[0037] In this embodiment, bevels 9 are provided on both sides at the upper end of the arc-shaped groove 10. The bevels 9 and the arc-shaped groove 10 are integrally provided. The setting of the bevels can increase the diameter of the upper end of the arc-shaped groove 10, thereby facilitating the quick calibration and installation between the insertion rod 6 and the arc-shaped groove 10.

[0038] The present utility model is not limited to the above embodiments. Anyone should know that structural changes made under the inspiration of the present utility model, as long as they have the same or similar technical solutions as the present utility model, fall within the protection scope of the present utility model.
