As shown in fig. 2 and 9, the clutch element 7 includes a first clutch plate 71 and a second clutch plate 71a which are relatively overlapped, the clutch spring comprises a first clutch spring 70 and a second clutch spring 70a, the first clutch plate 71 is in a sheet-shaped cuboid shape, a first groove 710 is arranged on the inner side of the first clutch plate 71, a first intermediate diaphragm 711 capable of blocking the first groove 710 is provided at a position near the central region of the first groove 710, a first end wall 712 is provided at one end position of the first groove 710, the first groove 710 extends in a direction parallel to the long sides of the first clutch plate 71 at a middle position between the two long sides inside the first clutch plate 71, a first coupling hole 713 is provided at a middle region of the first groove 710, the first coupling hole 713 being a through hole and disposed between the first middle bulkhead 711 and the first end wall 712; the second clutch plate 71a is a plate-shaped rectangular parallelepiped, a second groove 710a is provided on the inner side of the second clutch plate 71a, a second intermediate transverse partition 711a capable of partitioning the second groove 710a is provided at a position near a central region of the second groove 710a, a second end wall 712a is provided at one end position of the second groove 710a, the second groove 710a extends in a direction parallel to the long sides of the second clutch plate 71a and at a middle position between the two long sides inside the second clutch plate 71a, a second coupling hole 713a is provided at a middle region of the second groove 710a, and the second coupling hole 713a is a through hole and is disposed between the second intermediate transverse partition 711a and the second end wall 712 a; the second clutch plate 71a is overlapped with the first clutch plate 71a but arranged in the opposite direction, the first clutch spring 70 is sandwiched between the first recess 710 and the second recess 710a and both ends thereof are restrained between the first intermediate diaphragm 711 and the second end wall 712a, the second clutch spring 70a is sandwiched between the first recess 710 and the second recess 710a and both ends thereof are restrained between the second intermediate diaphragm 711a and the first end wall 712, and the first clutch plate 71 and the second clutch plate 71a are relatively slid to a position of being displaced up and down in a free-drive state of the first clutch spring 70 and the second clutch spring 70 a. The head portions of the first clutch plate 71 and the second clutch plate 71a respectively remain projected out of the handle rotation shaft 22 in a free state.

According to the above technical solution, since the first clutch plate 71 and the second clutch plate 71a have the structure of the groove, the middle diaphragm and the end wall body, the structure can firstly strengthen the structural strength of the first clutch plate 71 and the second clutch plate 71a, which is beneficial for the configuration of the first clutch plate 71 and the second clutch plate 71a as thin-walled structures, thereby reducing the volume of the first clutch plate 71 and the second clutch plate 71a and further reducing the installation space required by the first clutch plate 71 and the second clutch plate 71 a. In addition, the first clutch spring 70 and the second clutch spring 70a can be conveniently and skillfully accommodated therebetween, and such an installation manner is not only favorable for reducing the overall volume of the clutch element 7 and the clutch springs (70, 70 a), but also endows the first clutch plate 71 and the second clutch plate 71a with a length adjustment characteristic that the first clutch plate 71 and the second clutch plate 71a can relatively slide along the length direction thereof to adjust the overall total length thereof. Next, the clutch element 7 and the clutch spring (70, 70 a) are smartly mounted on the handle rotation shaft 22 through the radial hole 53, so that the internal space of the handle rotation shaft 22 is fully utilized, the occupation of the external mounting space of the handle rotation shaft 22 is reduced, the handle rotation shaft 22 can be radially or axially limited by the first clutch plate 71 and the second clutch plate 71a in a state that the head portion of the first clutch plate 71 and the head portion of the second clutch plate 71a respectively extend out of the handle rotation shaft 22, and the limitation of the handle rotation shaft 22 can be released by adjusting the overall total length of the first clutch plate 71 and the second clutch plate 71 a.

As shown in fig. 2, the rear end head of the tap lever 6 is tapered to have a tapered end 64, and the tapered end 64 has a tapered tip 641. The tapered end 64 of the tap lever 6 is flat, and the first combining hole 713 and the second combining hole 713a are elongated and fit with the tapered end 64 of the tap lever 6. The tap lever 6 is used for transmitting an external pushing force to extend into the first combining hole 713 and the second combining hole 713a so as to drive the two end heads of the clutch element 7 to retract into the radial holes 53. Specifically, when the tap lever 6 is axially moved rearward, the inclined surface 642 of the tapered end portion 64 engages with the right bore side wall of the first engagement hole 713, i.e., the first intermediate diaphragm 711 in this embodiment, to draw the head portion of the first clutch plate 71 fully or partially back into the radial bore 53. Also, when the head portion of the second clutch plate 71a protrudes out of the radial hole 53, the center of the second engaging hole 713a is also offset from the axial center of the tap lever 6. When the tap lever 6 is moved axially rearward, it is likewise possible to draw the head of the second clutch plate 71a fully or partially back into the radial bore 53. When the tap lever 6 is axially moved forward by the pushing action of the tap lever spring 63 and the tapered end 64 thereof gradually exits the first and second coupling holes 713 and 713a, the head of the clutch element 7 is reset to protrude out of the radial hole 53 by the driving of the clutch spring (70, 70 a), the centers of the first and second coupling holes 713 and 713a are deviated from the axial center of the tap lever 6 but the rear tapered tip 641 of the tap lever 6 is still retained in the first and second coupling holes 713 and 713 a. It follows that the telescopic movement of the clutch element 7 can be controlled by controlling the axial forward and backward movement of the tap lever 6. In addition, the structure that the rear end taper 641 of the tap lever 6 is retained in the first combining hole 713 and the second combining hole 713a can prevent the first clutch plate 71 and the second clutch plate 71a from sliding excessively relative to each other and completely disengaging from the handle rotating shaft 22, and the tap lever 6 can also play a role of radial limitation on the first clutch plate 71 and the second clutch plate 71 a.

As shown in fig. 11, a raised edge 11 surrounding the panel hole 10 is further disposed on the inner side of the lock inner panel 1, the raised edge 11 and the lock inner panel 1 are of an integral structure, but in other embodiments, a split structure may be provided between the raised edge 11 and the lock inner panel 1. A notch part 110 capable of receiving the head part of the clutch element 7 is arranged on the convex edge 11, when the clutch element 7 is in a free state, the head part of the clutch element 7 extends out and is inserted into the notch part 110, and the head part of the clutch element 7 is matched with a side vertical wall surface 111 forming the notch part 110 to limit the rotation of the handle rotating shaft 22; when the tap lever 6 moves axially backward, the head of the clutch element 7 can be driven to exit the notch 110, so that the handle rotation shaft 22 can rotate. According to the above technical solution, since the head of the clutch element 7 is matched with the side vertical wall 111 forming the notch 110 to limit the handle rotation shaft 22 from rotating, the notch 110 has a simple structure and is easy to manufacture, and the structure of the notch on the protruding edge 11 is beneficial to further simplifying the clutch structure of the lock 100. In addition, the head of the first clutch plate 71 and the head of the second clutch plate 71a can respectively extend out of the handle rotating shaft 22 to be matched with the notch 110 to limit the rotation of the handle rotating shaft 22, so that the rotation of the handle rotating shaft 22 can still be limited by matching the head of the first clutch plate 71 or the head of the second clutch plate 71a with the notch 110 after the handle portion 21 carries the handle rotating shaft 22 to rotate for 180 degrees and is reversed. The double clutch plate structure of the clutch element 7 including the first clutch plate 71 and the second clutch plate 71a provides a feasible technical basis for achieving the radial positioning of the handle in the forward and backward directions. In other embodiments, the side standing wall may be provided on other structures, such as a standing post, a standing wall, etc., so that the head of the clutch element is protruded and coupled to a side of the side standing wall when the clutch element is in a free state, and the side standing wall is used for restraining the head of the clutch element in one rotational direction so that the handle rotation shaft cannot rotate in the one rotational direction.

In order to be able to drive the head of the clutch element to retract into the radial bore by means of the tap lever, in other embodiments, a configuration as shown in fig. 10 can also be used. The clutch element 7' is a block, and a clutch spring 70' is arranged between the clutch element 7' and the hole bottom wall of the radial hole 53', and the clutch spring 70' is used for driving the head part of the clutch element 7' to keep extending out of the radial hole 53 '. An axially extending guide bevel 713 'is provided on the clutch element 7'. When the tap lever 6 'is moved axially backwards, the head of the clutch element 7' can be driven to retract into the radial bore 53 by its rear end 64 'abutting against the guide ramp 713'.

As shown in fig. 2 and 12, an electric driver 200 is further disposed on the inner side of the lock inner panel 1, the electric driver 200 includes a torque output arm 201, the torque output arm 201 extends toward the clutch element 7, the electric driver 200 is configured to push the clutch element 7 away from the notch 110 when the torque output arm 201 is extended by its operation so as to allow the handle spindle 22 to rotate, and the electric driver 200 is further configured to reset the clutch element 7 into the notch 110 when the torque output arm 201 is retracted by its operation so as to prevent the handle spindle 22 from rotating. According to the above technical solution, the lock 100 can not only manually control the movement of the clutch element 7 through the poke rod 6, but also automatically control the movement of the clutch element 7 through the electric driver 200. Since the outer door handle 2a and the inner door handle 2 are connected together by the square iron 31, the outer door handle 2a cannot be rotated when the inner door handle 2 is locked so as not to be rotated. In order to enable a person standing outside the door to unlock the lock by rotating the outer door handle 2a, a central controller (not shown) is disposed inside the lock inner panel 1, and a door opening signal pickup unit (not shown) is disposed outside the lock outer panel 1a, wherein the door opening signal pickup unit (not shown) may be a fingerprint information collector, an ic card signal collector, or the like. The door opening signal pickup unit confirms that the door opening signal belongs to a correct door opening signal and feeds the correct door opening signal back to the central controller, and the central controller controls the electric driver 200 to act. A person standing outside the door in this way can unlock the inner door handle 2 by inputting a correct door opening signal, thereby unlocking the outer door handle 2 a.

In order to enable the inner door handle 2 to be automatically reset after being rotated in the radial direction, as shown in fig. 11, 12, 13 and 14, the inner door handle lock further comprises a positioning angle code 9 and a door handle reset driver which are arranged on the inner side of the lock inner panel 1. The positioning angle 9 is connected to the rear end of the handle rotating shaft 22, and the positioning angle 9 abuts against the door handle reset driver. The door handle reset driver is used for providing positive and negative rotation reset power for the handle rotating shaft 22 through the positioning angle code 9. The door handle return actuator includes a pair of claw pieces (8, 8 a) and claw springs (84, 84 a) capable of rotationally returning the claw pieces (8, 8 a). The horn piece 8 has the same structure as the horn piece 8a, and the structure of the horn piece 8 will be explained as an example. The cleat 8 has a cleat center hole 80 and a radially protruding cleat 81, and the cleat 8 is a pair of radially protruding protrusions (82, 83), and the protrusions (82, 83) are arranged spaced apart from each other in a radial direction so as to form an included angle therebetween. Of course, in other embodiments, such as shown in fig. 15, the horn 81' may also be a radially extending protrusion that extends continuously in a radial direction to have a fan-shaped area. A fixing column 12 is further arranged on the inner side of the lock inner panel 1, and the fixing column 12 is located on the side edge of the protruding edge 11 and is spaced from the protruding edge by a certain distance. The pair of the claw pieces (8, 8 a) are movably sleeved at the rear end of the handle rotating shaft 22 in a front-back manner through claw piece center holes (80, 80 a), and the claws (81, 81 a) of the pair of the claw pieces (8, 8 a) are respectively arranged at two sides of the fixed column 12. Spring positioning columns (13, 13 a) are further arranged on the inner side of the lock inner panel 1, the claw spring 84 is connected between the protrusion 82 and the spring positioning column 13, and the claw spring 84a is connected between the protrusion 82a and the spring positioning column 13 a. The positioning corner brace 9 is provided with a corner brace center hole 90, and a pair of clamping arms (93, 93 a) extending oppositely are arranged on the inner hole wall of the corner brace center hole 90. A pair of slit grooves (55, 55 a) are provided at the rear end of the handle rotation shaft 22. The positioning corner brace 9 is sleeved at the rear end of the handle rotating shaft 22 through the corner brace center hole 90 and detachably connected, and the clamping arms (93 and 93 a) are respectively clamped in the split grooves (55 and 55 a). A pair of connecting holes (91, 91 a) are symmetrically arranged on the outer periphery of the positioning corner brace 9 at a certain radial distance from the corner brace central hole 90, a transmission column 92 extending axially is connected to the connecting holes 91, and the transmission column 92 is a screw in the embodiment. The transmission column 92 extends into an included angle space defined by two sheep horns (81, 81 a) of a pair of sheep horn sheets (8, 8 a), and the pair of sheep horn sheets (8, 8 a) are used for providing forward and reverse rotation resetting power for the handle rotating shaft 22 through the positioning angle bracket 9 by means of the driving force of the sheep horn springs (84, 84 a). When the handle rotating shaft 22 rotates in the forward direction (the direction indicated by the arrow in fig. 14), the positioning angle brace 9 rotates in the forward direction and drives the transmission column 92 to toggle the claw piece 8 to rotate in the forward direction, the claw piece 8 pulls the claw spring 84 to stretch, deform and store energy, when the torsion moment applied to the handle rotating shaft 22 is eliminated, the claw spring 84 recovers and releases potential energy, the claw piece 8 drives the transmission column 92 to drive the positioning angle brace 9 to rotate in the reverse direction, and therefore the handle rotating shaft 22 is driven to rotate in the reverse direction and reset. When the handle rotating shaft 22 rotates reversely, the transmission column 92 pulls the claw piece 8a to rotate reversely, so that the driving force of the claw spring 84a can be used for providing the power for the forward rotation reset for the handle rotating shaft 22 through the positioning angle bracket 9. When the direction of the inner door handle 2 needs to be changed, the inner door handle 2 is rotated after the transmission column 92 is detached, the hand holding portion 21 is switched from the right side to the left side, at this time, the connection hole 91a is positioned above an included angle space defined by two horns (81, 81 a) of the pair of horn sheets (8, 8 a), and the transmission column 92 is connected to the connection hole 91a and extends into the included angle space defined by the two horns (81, 81 a) of the pair of horn sheets (8, 8 a) again.
