[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] Reference Figure 1-5 A rotatable and adjustable spring sheet specification testing device for automotive lock holes is disclosed, comprising: The detection housing 2 is a frustum-shaped housing. The bottom of the detection housing 2 is provided with a detachable handle 1 for easy gripping and optical observation. The handle 1 is provided with a battery installation compartment for battery installation. The detection housing 2 is provided with an illumination lamp 4 to provide local illumination during the detection process and ensure that the inside of the keyhole is clearly visible. The detection mechanism 3 includes a fixed tube 33 fixedly connected to the smaller diameter side of the detection housing 2 as a rotating support base. A movable ring 34 is rotatably connected to the outside of the fixed tube 33. A through mounting hole 35 is opened on the outside of the movable ring 34. A detachable insert rod 31 is provided inside the mounting hole 35 for inserting into the lock hole and performing actuation detection on the spring plate.

[0021] Specifically, the outer side of the movable ring 34 has a first screw hole 36 extending into the mounting hole 35. The inner wall of the first screw hole 36 is threaded with a mounting bolt 32. The top of the insert rod 31 has a limiting groove 37. The mounting bolt 32 passes through the first screw hole 36 and extends into the limiting groove 37. When replacing, simply loosen the mounting bolt 32 to remove it from the limiting groove 37, and the insert rod 31 can be pulled out of the mounting hole 35. After installing the new rod, tighten the mounting bolt 32 to make it extend into the limiting groove 37 to complete the fixation.

[0022] Specifically, the movable ring 34 has a second screw hole 38 symmetrically distributed with the first screw hole 36 on its outer side, and the second screw hole 38 extends into the interior of the movable ring 34. The inner wall of the second screw hole 38 is threaded with a limit bolt 39. The outer side of the fixed tube 33 has an annular anti-slip groove distributed at equal intervals to increase friction and prevent slippage. The limit bolt 39 passes through the second screw hole 38 and fits tightly against the outer side of the fixed tube 33. By loosening the limit bolt 39, the movable ring 34 can drive the insertion rod 31 to rotate freely on the fixed tube 33. After adjusting to the required angle, tighten the limit bolt 39 so that its end is tightly against the outer surface of the fixed tube 33, thereby fixing the direction of the insertion rod 31.

[0023] Specifically, the end of the insert lever 31 away from the movable ring 34 is flat, and the end of the insert lever 31 away from the movable ring 34 intersects with the beam of the illumination lamp 4. The flat shape of one end of the insert lever 31 facilitates contact with the spring plate, and the position of this end intersects with the beam of the illumination lamp 4 to ensure that the light reaches the detection area directly during operation.

[0024] Specifically, a detachable sleeve is provided on the side of the outer casing 2 away from the fixed tube 33, and an observation lens is provided on the inner wall of the sleeve to facilitate the inspection personnel to magnify and observe the inside of the keyhole, thereby improving the inspection accuracy.

[0025] The workflow of this utility model is as follows: When testing the keyhole, turn on the light 4 and align the lever 31 with the keyhole of the car to be tested; By gently pushing the insert lever 31 into the lock hole using handle 1, the spring plates are turned from the inside to the outside using its flat end, and the lighting lamp 4 provides illumination simultaneously. The inspectors used a magnifying glass to observe the inside of the keyhole step by step to determine whether the specifications and condition of the spring sheet met the requirements. When encountering lock holes with different installation angles, first loosen the limiting bolt 39 to remove the limiting of the movable ring 34. Then, rotate the movable ring 34 to adjust the angle of the insert lever 31 so that it is aligned with the lock hole. Then tighten the limiting bolt 39 to fix it. When the plug lever 31 is damaged or needs to be replaced, simply loosen the mounting bolt 32 to pull it out and replace it with a new lever. After replacement, tighten the mounting bolt 32 again to restore its use.

[0026] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
