Claims (6)
1. A snap-on quick-lock device with adjustable locking length, comprising:
a holder having a holding pin shaft formed thereon;
the locking base is hinged with a swinging part, and an external thread or an internal thread hole is formed on the swinging part;
one end of the hook head screw rod is connected with a hook head which is in matched hanging connection with the holding pin shaft, and the other end of the hook head screw rod is provided with an internal thread hole or an external thread;

the swing portion includes:
one end of the rotating frame is hinged to the locking base;
the swing rod is hinged to the middle of the rotary frame, and an external thread or an internal thread hole is formed in the swing rod;
the rotating frame is turned upwards and drives the swing rod to move to release the locking of the hook head and the retaining pin shaft, and the rotating frame is turned downwards and drives the swing rod to move to enable the hook head and the retaining pin shaft to be locked;
a limiting device is hinged on the rotating frame, and when the hook head is locked with the retaining pin shaft, the limiting device is rotated to be matched with the locking base for limiting;
the stop device includes:
the limiting pin shaft is rotatably connected to the other end of the rotating frame;
the locking key is arranged on the limiting pin shaft and rotates synchronously with the limiting pin shaft;
when the hook head is locked with the retaining pin shaft, the limiting pin shaft is arranged in the limiting groove, and the locking key is rotated downwards to limit the limiting pin shaft in the limiting groove; when unlocking, the locking key is turned upwards to enable the limiting pin shaft and the limiting groove to be free from limiting;
the end part of the limiting pin shaft is of a long strip-shaped block structure, the limiting groove is open at the upper end, the bottom of the limiting groove extends downwards in an inclined mode in the direction away from the hook head, and the size of the upper end opening of the limiting groove is smaller than that of the middle of the limiting groove, so that the end part of the limiting pin shaft is limited in the limiting groove after rotating.
2. The hasp type quick lock device with adjustable locking length as claimed in claim 1, wherein said limiting device further comprises a spring, said spring is sleeved on said limiting pin shaft and rotates synchronously with said limiting pin shaft; when the locking key is turned upwards to enable the limiting pin shaft and the limiting groove to be relieved from limiting, the spring is in a pressed state; when locking, the locking key is driven to rotate downwards by the elastic restoring force of the spring.
3. The hasp type quick lock device with adjustable locking length as claimed in claim 2 wherein said rotating frame is H-shaped, a baffle is connected to the middle of said rotating frame, and said limit pin is rotatably connected to the side of said baffle away from said hook head; one end of the spring is limited on the limiting pin shaft, and the other end of the spring is abutted against the baffle.
4. A snap-on quick lock device with adjustable locking length as claimed in any one of claims 1 to 3, wherein the end of the limiting pin is convex and round in cross section, and the bottom of the limiting groove is circular arc.
5. A snap-on quick lock device with adjustable locking length as claimed in any one of claims 1 to 3, characterized in that the locking base is U-shaped in cross-section, and the swinging part is hinged inside the locking base.
6. The snap-on quick lock device with adjustable locking length as claimed in claim 5, wherein a boss is formed on the inner side of the bottom of the end of the locking base away from the hook head to engage with the swing part.
