Specifically, the movable connection is realized between the first base 122 and the fastening portion 200 through threads, a first connection hole is formed in the first base 122, an internal thread is formed in the first connection hole, correspondingly, an external thread is formed in the fastening portion 200, the fastening portion 200 is connected in the first connection hole through a thread fit, and the first base 122 is movably connected in the axial direction of the first connection hole.
As the fastening part 200 rotates, the fastening part 200 moves back and forth relative to the first base 122, away from or close to the second base 121, clamping or releasing the chain to be disassembled.
Similarly, the fastening portion 200 and the detaching portion 300 are movably connected through a screw, a second connecting hole is formed in the fastening portion 200, the second connecting hole is coaxial with the first connecting hole, an internal thread is formed in the second connecting hole, an external thread is formed in the detaching portion 300, and the detaching portion 300 is movably connected to the fastening portion 200 along the axial direction of the second connecting hole.
As the detaching part 300 rotates, the detaching part 300 moves back and forth relative to the fastening part 200 and the first base 122, the ejector pin 320 gradually approaches the second base 121 to detach the pin, and after the reverse rotation, the ejector pin 320 exits into the fastening part 200.
In order to facilitate the operation of the fastening part 200 and to limit the specific position thereof, the bottom end of the fastening part 200 away from the second base 121 is provided with a stopper 210.
The limiting portion 210 is formed with a clamping surface, for example, the limiting portion 210 is a nut structure, so that a user can conveniently rotate the fastening portion 200 by using a tool such as a wrench, and the limiting portion 210 is used for limiting the maximum displacement of the fastening portion 200 extending into the first connecting hole.
The detachable portion 300 is formed with a rotation link 310, the rotation link 310 is perpendicular to the axial direction of the second connection hole, and the rotation link 310 is rotated around the direction perpendicular to the central axis of the second connection hole to rotate the detachable portion 300, thereby implementing the forward or backward movement.
In order to improve comfort of a user, a rotation handle 311 is formed at the end of the rotation link 310, and an anti-slip pattern is formed on the rotation handle 311.
The size of the disassembly station formed between the first base 122 and the second base 121 is greater than the thickness of the chain to be disassembled.
The specific working process comprises the following steps:
as shown in fig. 1, before use, the fastening portion 200 is retracted into the first base 122, the thimble 320 is retracted into the fastening portion 200, when the chain needs to be disassembled and replaced, first, the chain is placed in the disassembling station, and the pin to be disassembled corresponds to the position of the avoiding groove 1211;
referring to fig. 2, the stopper 210 is then clamped by a tool such as a wrench, the fastening portion 200 is rotated, and the chain to be disassembled is clamped between the fastening portion 200 and the second base 121, so as to fix the chain.
Referring to fig. 3, the operator holds the rotating handle 311, rotates the rotating link 310, moves the detaching portion 300 forward in the second connecting hole, and then continues to rotate the ejector pin 320, so that the ejector pin 320 pushes the pin out of the escape slot 1211 to detach the pin.
Subsequently, the rotation link 310 is rotated in the reverse direction, the thimble 320 is retracted into the second connection hole, and then the fastening portion 200 is rotated in the reverse direction, releasing the chain to be disassembled.
