The fixing component at one end of the pin 2 is used to fix the tongue 3, and the fixing component is detachably connected to the pin 2. When the fixing component and the pin 2 are rotated and disassembled by a certain angle, the pin 2 It can be withdrawn and inserted from the holes at the two corners of the main hook 1, which makes it convenient to connect with connecting media such as slings, wire ropes, chains, etc. The rebound component at the other end of the pin 2 ensures a tight fit between the tongue 3 and the main hook 1; when the connecting medium needs to be placed in the main hook 1, the fixing part on the pin 2 is pulled in the opposite direction of the rebound component for a certain distance to release the fit between the tongue 3 and the main hook 1, and the tongue 3 is turned clockwise or counterclockwise to open the main hook 1. When the connecting medium is placed in the main hook 1 and needs to be closed, the reverse operation can be performed.
[0026] Further, the tongue stopper 3 includes a tongue and a tongue handle. The tongue is provided with a safety groove 4, which is adapted to the main hook 1. The tongue has two extension angles, which are in contact with the main hook 1. A pin hole is provided on the tongue handle, and the pin 2 is slidably connected to the tongue handle through the pin hole.
[0027] Furthermore, the hook tip of the main hook 1 is sunken into the safety groove 4 of the tongue. When the tongue stop 3 is closed, the connecting medium touches the tongue, and the rebound assembly connects the pin 2 with the tongue handle and the main hook 1. The tongue is adapted to the safety groove 4 to prevent the tongue from shaking, thereby preventing the connecting medium from falling off from the main hook 1.
[0028] Furthermore, a groove chamber is provided in one end of the pin 2 away from the rebound component, and the fixing component is detachably connected to the groove chamber.
[0029] Furthermore, the groove chamber provided in the pin 2 mainly serves the function of connecting with the fixing component, providing space and support for the connection between the fixing component and the pin 2.
[0030] Further, the fixing component includes a hollow ring 8, the hollow ring 8 is in contact with the pin 2, the hollow ring 8 is in contact with the tongue handle, a circular hole is opened in the middle of the hollow ring 8, a fixing block 9 is fixedly connected to the side wall of the hollow ring 8, the fixing block 9 is slidably connected to the groove chamber, the fixing block 9 is opened with a rotating hole 10 which communicates with the circular hole, a fixing component is rotatably connected in the rotating hole 10, and the fixing component is rotatably connected to the groove chamber.
[0031] Furthermore, the outer ring portion of the hollow ring 8 contacts the tongue handle to realize the limiting function of the tongue handle. The circular hole opened in the center of the hollow ring 8 facilitates the operation of the fixing assembly. The fixing block 9 provides radial support for the hollow ring 8 through an axial sliding connection with the groove chamber to prevent the hollow ring 8 from radial shaking. The fixing assembly provides axial support for the hollow ring 8 through a rotational connection with the groove chamber to control the disassembly and assembly of the hollow ring 8 and the pin 2.
[0032] Furthermore, the fixing assembly includes a rotating shaft 12, which is rotatably connected to the rotating hole 10. A twist block 11 is fixedly connected to one end of the rotating shaft 12, and a rotating block 14 is fixedly connected to the other end of the rotating shaft 12.
