[0024] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0025] like Figure 1 and Figure 2 and Figure 3 As shown, an ignition coil spring height detection tool includes a positioning component 1 and a detection component 2. The positioning component 1 includes a left vertical plate 11, a right vertical plate 12, a back plate 13, and a bottom rod 14. The left vertical plate 11, the right vertical plate 12, and the bottom rod 14 are all set on the back plate 13. The left vertical plate 11 and the right vertical plate 12 are set on both sides of the bottom rod 14. A left slide 15 is formed between the left vertical plate 11 and the back plate 13, and a right slide 16 is formed between the right vertical plate 12 and the back plate 13. The bottom end of the ignition coil spring overlaps the bottom rod 14, and the side of the ignition coil spring is laid flat on the back plate 13. The left vertical plate 11 and the right vertical plate 12 have the same length.

[0026] The detection assembly 2 includes a left support rod 21, a right support rod 22, a top rod 23, and a cover plate 24. The left support rod 21 is located in the left slide rail 15, and part of the left support rod 21 is covered by the left vertical plate 11. The right support rod 22 is located in the right slide rail 16, and part of the right support rod 22 is covered by the right vertical plate 12. The top rod 23 is slidably located in the left slide rail 15 and the right slide rail 16. The left support rod 21 and the right support rod 22 are located between the top rod 23 and the bottom rod 14. The cover plate 24 is laid flat between the left support rod 21 and the right support rod 22, and both ends of the cover plate 24 overlap the left support rod 21 and the right support rod 22.

[0027] The space between the bottom rod 14 and the top rod 23 is used to place the ignition coil spring 4 to be tested. If the length of the ignition coil spring 4 is greater than the distance between the bottom rod 14 and the top rod 23, the ignition coil spring 4 is too long and unqualified. The left support rod 21 and the right support rod 22 have the same height. The length between the bottom rod 14 and the top rod 23 is used to detect the upper deviation of the ignition coil spring 4. The height of the cover plate 24 is used to detect the lower deviation of the ignition coil spring 4. There is a gap 5 between the cover plate 24 and the top rod 23. If part of the ignition coil spring 4 falls within the gap 5, it means that the upper and lower deviations of the ignition coil spring 4 are qualified; otherwise, the upper and lower deviations of the ignition coil spring 4 are unqualified.

[0028] Depending on the height of the ignition coil spring 4, the left support rod 21 and right support rod 22 of the corresponding height are replaced, and the top rod 23 is supported by the left support rod 21 and right support rod 22.

[0029] A bolt 25 is provided on the top rod 23. The bolt 25 passes through the top rod 23. The back plate 13 is located on the moving path of the bolt 25. After the upper difference of the ignition coil spring 4 is determined between the top rod 23 and the bottom rod 14, the bolt 25 is rotated so that the bolt 25 abuts against the back plate 13. In this way, the top rod 23 is close to the left vertical plate 11 and the right vertical plate 12, and the position of the top rod 23 is fixed.

[0030] The left support rod 21 is partially set inside the left slide rail 15, and the right support rod 22 is partially set inside the right slide rail 16. The width of the left support rod 21 is wider than the left slide rail 15, and the width of the right support rod 22 is wider than the right slide rail 16. In this way, the left vertical plate 11 can only cover part of the left support rod 21, and the right vertical plate 12 can only cover part of the right support rod 22. The exposed parts of the left support rod 21 and the right support rod 22 are used to overlap the cover plate 24.

[0031] In other embodiments, the left support rod 21 is not required to be installed in the left slide rail 15, and the right support rod 22 is not required to be installed in the right slide rail 16.

[0032] The positioning assembly 1 also includes a stop bar 10, a left vertical plate 11 and a right vertical plate 12 connecting the two sides of the stop bar 10, the stop bar 10 and the bottom bar 14 are respectively set at both ends of the back plate 13, the stop bar 10 is located on the sliding path of the top bar 23, and the stop bar 10 can prevent the top bar 23 from falling out of the left slide rail 15 and the right slide rail 16.

[0033] A first positioning bolt 17 is provided on the left vertical plate 11. The first positioning bolt 17 is used to fix the left vertical plate 11 and the back plate 13. The second positioning bolt is used to fix the right vertical plate 12 and the back plate 13. In this way, the back plate 13 is more firmly fixed to the left vertical plate 11 and the right vertical plate 12.

[0034] The height of the cover plate 24 is shorter than that of the left support rod 21 and the right support rod 22. The bottom end of the cover plate 24 is flush with the bottom rod 14. As a result, the cover plate 24 cannot be completely laid flat on the left support rod 21 and the right support rod 22. There is always a gap 5 between the cover plate 24 and the top rod 23.

[0035] A wristband 3 is provided on the cover plate 24. The wristband 3 is easy for the operator to grasp and facilitates the closing or opening of the cover plate 24.

[0036] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the protection scope of this utility model.
