Referring to fig. 2, further, the linkage member 8 can rotate relative to the first fork 3, the linkage member 8 is further provided with a linkage block 82, the first fork 3 is further provided with an avoidance empty groove 32, and the linkage block 82 is arranged in the avoidance empty groove 32. When a user rotates the second shifting fork 4 to control the bolt 2 to stretch out and draw back through other control modes, the first shifting fork 3 rotates along with the rotation, but the avoidance empty groove 32 provides an avoidance space for the linkage block 82, so that under the condition, the rotation of the first shifting fork 3 is not influenced, the linkage part 8 is not driven, the linkage part 8 keeps static, the handle connected with the linkage part does not rotate, the linkage handle does not rotate due to other control modes, three operation components can be used relatively independently, and the use experience of the user and the service life of the door lock are improved. When a user controls the switch lock through the handle, the linkage piece 8 is driven by the handle to rotate, the first driving block 82 is in contact with one end face of the avoidance empty groove 32 and drives the first shifting fork 3 to rotate, and normal driving of the switch lock by the handle is achieved.
Further, this single spring bolt door lock of many control modes still includes spacing torsional spring 10, and its both ends articulate respectively to second shift fork 4 and shell 1.

The restraining torsion spring 10 is always in a compressed state. In the process that the limiting torsion spring 10 is changed from the first posture to the second posture, the limiting torsion spring 10 is compressed further first, and is released after crossing the maximum compression posture, and the elastic potential energy of the limiting torsion spring is increased and then reduced. By adopting the design, the limiting torsion spring 10 can perform certain assistance in the rear half section of unlocking or the rear half section of locking, so that the hand feeling of locking and unlocking is improved; and when the bolt 2 is in the complete exposure or retraction state, the limiting torsion spring 10 can force the bolt 2 to be positioned at the unlocking or locking position, and has a self-locking function.
The flow of the multi-control mode single-bolt door lock for controlling unlocking through the handle is described as follows:
referring to fig. 2, at this time, the latch 2 is completely exposed from the housing 1, the linkage 8 is in an initial state, the handle connected thereto is horizontally disposed, the buffer 5 is in a maximum compression state, and the limit torsion spring 10 is in a first posture.
Referring to fig. 3, when the handle is pressed down, the linkage 8 connected with the handle rotates clockwise, and the buffer 5 is driven by the linkage arm 7 and is in a stretching state. The linkage block 82 on the linkage piece 8 contacts with one side of the avoidance empty groove 32 on the first shifting fork 3 and drives the first shifting fork 3 to rotate clockwise. The first shifting bar 31 drives the second shifting bar 41 to further drive the second shifting fork 4 to rotate anticlockwise. At this time, the push-pull bar 42 on the second fork 4 drives the bolt 2 to retract. The limiting torsion spring 10 changes to a second posture, the second shifting fork 4 is positioned, and the bolt 2 is kept in a retracting state.
Referring to fig. 4, when the external force on the handle is removed, the reset torsion spring 9 drives the linkage member 8 to return to the initial state, the handle returns to the horizontal position, the linkage block 82 is not in contact with one end surface of the avoidance empty groove 32, the first shifting fork 3 is not driven, and the state of the bolt 2 is not changed. The buffer 5 is compressed to buffer the resetting of the handle and reduce the generated noise. Therefore, the bolt 2 retracts, the handle returns to the original position, and unlocking is completed.
When the lock is closed, the handle is lifted to drive the lock to be closed, the working process is similar to that of unlocking, and the detailed description is omitted.
The flow of the multi-control mode single-bolt door lock for controlling unlocking through the knob is described as follows:
referring to fig. 5, the latch 2 is completely exposed from the housing 1, and the position-limiting torsion spring 10 is in the first posture.
Referring to fig. 6, the knob rotating block 11 rotates clockwise, and the shifting block 111 thereon shifts the shifting portion 43 of the second fork 4 and drives the second fork 4 to rotate counterclockwise. At this time, the first shifting fork 3 is also linked by the second shifting fork 4, but the avoidance empty groove 32 does not drive the linkage block 82, the linkage piece 8 is not driven, and the handle does not rotate.
