[0025] It should be noted that like numbers and letters represent similar items in the following figures, so once an item is defined or described in one figure, it will not need to be further discussed and described in detail in the description of the subsequent figures.

[0026] In order to solve the technical problems in the background technology, such as Figure 1-4 As shown, the present application provides a technical solution: a new pin detection tool, which has the following features:

[0027] The support platform 1 is the main component of the inspection tool. It is square in shape to provide a stable inspection platform. The support platform 1 comprises a top surface 2, which serves as the placement surface for the pin 6 to be inspected; a bottom surface 3, parallel to the top surface 2, which houses the guide ramp 9 and bracket 7; and four side surfaces 4, which connect the top and bottom surfaces 3 and form the outer structure of the support platform 1. The top surface 2 of the support platform 1 is provided with a number of through-holes 5, which extend vertically through the top and bottom surfaces 3. The inner diameter of each through-hole 5 is designed to match the outer diameter of the pin 6 to ensure smooth insertion and inspection. Specifically, the inner diameter of the through-hole 5 is 0.5-1 mm larger than the outer diameter of the pin 6. The bracket 7 is removable to facilitate removal from the bottom surface 3 of the support platform 1 when not in use. Furthermore, during inspection, when the pin 6 to be inspected is inserted into the through-hole 5, a portion of its structure is exposed. This exposed portion is compared with the bracket 7 to verify that the length of the pin 6 meets the requirements. Therefore, the bracket 7 can be set to different heights to accommodate different lengths of the pins 6 to be tested. The bracket 7 is connected to the bottom surface 3 of the support platform 1 by bolts, snaps or other suitable connection mechanisms. The support legs 8 are set on the top surface 2 of the support platform 1 and are evenly distributed around the support platform 1. When the support platform 1 needs to be flipped, the support legs 8 will form a plane and contact the workbench, thereby horizontally supporting the entire support platform 1 to ensure stability after flipping. For some pins 6 to be tested that do not meet the requirements, if it is due to the smooth movement of the positioning beads 10, the support platform 1 can be flipped to the second working state, that is, the support legs 8 support the entire support platform 1. At this time, the positioning beads 10 can be checked and appropriately adjusted using tools. The guide bevel 9 is designed to be trumpet-shaped, which helps to guide the positioning beads 10 of the pins 6 to be tested to retract smoothly. The guide bevel 9 is located on the top surface 2 and the bottom surface 3, and is concentric with the through hole 5 to ensure that the positioning beads 10 of the pins 6 to be tested can move smoothly along the guide bevel 9 during the insertion and removal process. The inner diameter of one end of the guide ramp 9 where it connects to the through hole 5 is the same as that of the through hole 5, while the inner diameter of the other end is larger than that of the through hole 5, forming a gradually narrowing channel from the outside to the inside to facilitate the retraction of the positioning bead 10. A spring is installed inside the pin to push the positioning bead 10 out. This pin structure is common knowledge in the art and will not be described in detail here.

[0028] During testing, first insert the pin 6 to be tested into the through hole 5, and the positioning bead 10 contacts the starting end of the guide bevel 9, and slowly retracts until the pin 6 to be tested is fully inserted into the through hole 5, and the bottom wall of the end of the pin 6 to be tested contacts the top surface 2. Then, by adapting to the through hole 5, check whether the diameter of the pin meets the requirements; by comparing the protruding end with the bracket 7, observe whether its overall length meets the requirements; and by observing whether the insertion is smooth, check whether its positioning bead 10 is qualified. After the test is completed, the pin is pulled out, and the positioning bead 10 retracts smoothly along the guide bevel 9, ready for the next test. If some pins do not meet the requirements, especially because the positioning bead 10 is not smooth, the entire support platform 1 can be turned over and the positioning bead 10 can be adjusted and tested.

[0029] It should be pointed out that the handle 11 is located on the side 4 of the support table 1. Specifically, it can be set at the center position of one of the side surfaces 4 of the support table 1. The handle 11 can be made of the same material as the support table 1, or a different material can be selected, such as rubber, plastic or soft material, to increase friction and ensure that the user can hold the handle 11 firmly when flipping the support table 1. The new pin detection tool with the handle 11 added not only provides a stable detection platform, but also makes the entire flipping operation more humane and convenient through the design of the handle 11. This design is particularly suitable for situations where the support table 1 needs to be frequently flipped for detection, which greatly improves work efficiency.

[0030] Furthermore, handle 11 is provided on side 4 of support platform 1, with its upper surface designed to be flush with the upper surfaces of support legs 8. When support platform 1 is flipped, the upper surface of handle 11 and the upper surface of support legs 8 are flush with each other, forming a stable support surface. Because the upper surface of handle 11 is coplanar with the plane formed by support legs 8, support platform 1 can rely on these structures to provide stable support after flipping, which increases stability and safety.

[0031] It should be noted that if Figure 2As shown, a tool slot 12 is provided on the side 4 of the support platform 1. The tool slot 12 is a slot-shaped structure, which is a space specially designed for storing detection tools. Its existence greatly facilitates the access and storage of tools required for testing and adjusting the positioning beads 10. The tool slot 12 can be single, or multiple side by side or arranged in a surrounding manner to meet the storage needs of different tools. The shape of the tool slot 12 can be a long strip, a square or any shape suitable for storing tools. Its size design should take into account the size and number of stored tools to ensure that the tools can be stably placed in the slot and are easy to access when needed. In order to protect the tools and prevent the intrusion of dust and other impurities, the tool slot 12 can be equipped with a lid with one side hinged to the support platform 1. This lid can cover the tool slot 12 when it is not in use to protect the tools inside. When not in use, the lid is magnetically attached to the support platform 1. When in use, the ring set on the lid can be pulled open.

[0032] Furthermore, a scale 13 is provided on the side 4 of the support platform 1, adjacent to the tool slot 12. The scale 13 may be a series of equally spaced markings for measuring dimensions of the pin 6 to be inspected, such as diameter, length, etc. The size of the scale 13 should be designed based on the maximum dimension of the pin 6 to be inspected to ensure that the full range of possible measurements can be covered.

[0033] It should be noted that the bracket 7 is an integral part of the pin detection tool and consists of three main parts: a support plate 14, a connecting plate 15, and a support column 16. Together, these components form a stable structure that supports and secures the other parts of the pin detection tool. The connecting plate 15 connects the bracket 7 to the bottom surface 3 of the support platform 1. One end of the connecting plate 15 is connected to the bottom surface 3 of the support platform 1, either by bolting or by snapping. The support plate 14 is fixedly connected to one end of the connecting plate 15. The support plate 14 is a flat plate. A mark can be placed on the support plate 14 to indicate alignment with the protruding end of the pin 6 to be tested, or the support plate 14 can be directly aligned with the protruding end of the pin 6 to facilitate checking whether the overall length of the pin 6 to be tested meets the requirements. The support column 16 is located at the other end of the connecting plate 15, opposite the support plate 14. The support column 16 can be one or more columnar structures perpendicular to the connecting plate 15. They provide additional support and stability, ensuring that the bracket 7 does not tilt or wobble during use. Fixing method of bracket 7: bracket 7 can be connected to support platform 1 in a variety of ways, such as detachable bolt connection, so that bracket 7 can be easily installed or removed when needed. This design allows the user to decide which size of bracket 7 to use according to actual use needs.

[0034] It should be noted that the reinforcing rib 17 is designed to be provided on the bracket 7 to enhance the structural strength and rigidity of the bracket 7. One side of the reinforcing rib 17 is connected to the support plate 14, and the other side is connected to the connecting plate 15. This design can effectively transfer the load and improve the stability and durability of the entire bracket 7.

[0035] It should be noted that a plurality of through holes 5 are designed on the support table 1, and the inner diameter of each through hole 5 is designed according to the specifications and diameter range of the pin 6 to be tested to ensure that it can adapt to pins of various sizes. This design makes the detection tool highly adaptable and flexible. These through holes 5 are evenly distributed on the top surface 2 of the support table 1, so as to facilitate the simultaneous detection of multiple pins or the selection of the most suitable through hole 5 for the detection of a single pin. In order to facilitate the user to identify and select the correct through hole 5 for detection, each through hole 5 can be provided with an identification, such as a diameter mark or number, which can be engraved near the through hole 5 or displayed in the form of a diagram on the top surface 2 of the support table 1.

[0036] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
