The cover plate 84 is installed on the annular side plate 813, and the square shaft seat 30 passes through the avoidance hole 841.

[0065] The utility model also discloses a door lock, comprising the clutch reversing device as described above.

[0066] How door locks work:

[0067] like Figures 5 to 9As shown, at this time, the lock plate 80 is vertically arranged, and two blocks 83 are defined as a first limit block 831 and a second limit block 832, wherein the second limit block 832 is arranged close to the exposed handle 100, and the two torsion ends 91 are defined as a first torsion bar 911 and a second torsion bar 912, at this time, the first torsion bar 911 is located between the top of the first limit block 831 and the arc block 82, the second torsion bar 912 is located between the arc block 82 and the top of the second limit block 832, the reversing member 70 is located at one end of the first torsion bar 911 away from the arc block 82, and the second protrusion 222 is located at one end of the second torsion bar 912 away from the arc block 82, and the handle 100 can swing up and down within a range of 90 degrees, and the second protrusion 222 and the reversing member 70 will not interfere with the block 83 during the rotation process;

[0068] When unlocking is required, the pushing assembly 10 first drives the clutch pin assembly 40 to move toward the middle side position of the handle seat 20, so that the two ends of the clutch pin assembly 40 are respectively inserted into the installation groove 321 and one of the positioning holes 50, and then when the handle 100 is pressed counterclockwise, the second protrusion 222 rotates counterclockwise with the handle 100. During the rotation process, the second protrusion 222 will press the second torsion bar 912 to rotate toward the arc block 82 side, while the first torsion bar 911 does not rotate due to the obstruction of the first limit block 831, and the square shaft seat 30 rotates with the handle seat 20 until the door lock is opened. At this time, the second torsion bar 912 does not need to touch the arc block 82. When the force on the handle 100 is removed, the second torsion bar 912 will drive the second protrusion 222 clockwise to return to the origin under the elastic action of the torsion spring 90, and the pushing assembly 10 and the clutch pin assembly 40 are both reset to the initial position;

[0069] When the handle 100 needs to be reversed 180 degrees, loosen the reversing member 70, rotate the handle seat 20 180 degrees clockwise until the first protrusion 221 abuts against the other side end of the limit body 32 in the square shaft seat 30, and then tighten the reversing member 70. At this time, the second protrusion 222 is located at the end of the first torsion bar 911 away from the arc block 82, and the reversing member 70 is located at the end of the second torsion bar 912 away from the arc block 82; the pushing assembly 10 first drives the clutch pin assembly 40 to move toward the middle side of the handle seat 20, so that the two ends of the clutch pin assembly 40 are respectively inserted into the mounting In the groove 321 and another positioning hole 50, when the handle 100 is pressed clockwise, the second protrusion 222 rotates clockwise with the handle 100. During the rotation, the second protrusion 222 will press the first torsion bar 911 to rotate toward the arc block 82, and the second torsion bar 912 will not rotate due to the obstruction of the second limit block 832 until the door lock is opened. At this time, the first torsion bar 911 does not need to touch the arc block 82. When the force on the handle 100 is removed, the first torsion bar 911 will drive the second protrusion 222 to return to the origin counterclockwise under the elastic action of the torsion spring 90.

[0070] To sum up, when the clutch reversing device of the utility model needs to be unlocked, the first protrusion 221 abuts against one side end of the limiting body 32, and the pushing component 10 pushes the clutch pin assembly 40 toward the position on one side of the middle part of the square shaft seat 30, so that the two ends of the clutch pin assembly 40 are respectively inserted into the mounting groove 321 and one of the positioning holes 50; when reversing is required, the pushing component 10 and the clutch pin assembly 40 are both reset, the handle seat 20 is rotated, the first protrusion 221 abuts against the other side end of the limiting body 32, and the pushing component 10 pushes the clutch pin assembly 40 toward the position on one side of the middle part of the square shaft seat 30, so that the two ends of the clutch pin assembly 40 are respectively inserted into the mounting groove 321 and the other positioning hole 50, thereby realizing the left and right reversing of the clutch reversing device. The clutch reversing device has only one clutch pin assembly 40, has a simple structure, can reduce costs, is convenient for reversing adjustment, has broad market prospects, and is convenient for large-scale promotion.
