Door opener

Abstract

The present application relates to a door opener. The power output generated by a drive motor (21) of the door opener can be transmitted to an output main shaft (31) by means of a transmission rotating shaft (222), and the coaxiality of the transmission rotating shaft (222) relative to the output main shaft (31) can be stably constrained by means of the positioning cooperation between a positioning sleeve (223) and a mounting base (11). Thus, the coaxiality constraint generated by the positioning sleeve (223) on the transmission rotating shaft (222) with the output main shaft (31) as the reference can suppress radial runout of the output main shaft (31) generated during rotation in response to power output, thereby helping to improve the stability of automatic opening and closing of door leaves.

Therefore, when the transmission shaft 222 and the output spindle 31 are drivingly connected and the output spindle 31 is driven to rotate synchronously by the power output generated by the driving motor 21, the coaxial constraint of the positioning sleeve 223 on the transmission shaft 222 can be used to suppress the radial movement of the output spindle 31 during synchronous rotation with the transmission shaft 222.

[0080] As can be seen from the above, according to the embodiment of the present application, the power output generated by the driving motor 21 of the door opener 90 can be transmitted to the output spindle 31 through the transmission shaft 222, and the coaxiality of the transmission shaft 222 relative to the output spindle 31 can be stably constrained through the positioning and matching of the positioning sleeve 223 and the mounting base 11. Therefore, the coaxial constraint of the positioning sleeve 223 on the transmission shaft 222 with respect to the output spindle 31 can suppress the radial movement of the output spindle 31 during rotation in response to the power output, thereby helping to improve the stability of the automatic opening and closing of the door leaf 95.

[0081] Exemplarily, in the embodiment of the present application, if the transmission module 22 further has the module housing 221 as described above, and the driving motor 21 is fixedly arranged on the module housing 221, the driving motor 21 fixedly arranged on the module housing 221 can be physically separated from the mounting base 11, so as to avoid the assembly stress generated between the driving motor 21 and the mounting base 11 from affecting the positioning accuracy of the positioning fit between the positioning sleeve 223 and the mounting base 11, and thus improve the accuracy of the coaxial constraint of the positioning sleeve 223 on the transmission shaft 222.

[0082] Exemplarily, in the embodiment of the present application, the driving motor 21 fixedly arranged on the module housing 221 can be suspended and supported by the module housing 221 on the side of the transmission module 22 facing away from the mounting base 11, in which case, if the transmission module 22 comprises the worm gear and the worm as described above, the worm can be arranged in a direction perpendicular to the mounting base 11, and the output shaft of the driving motor 21 can be in transmission connection with one end of the worm facing away from the mounting base 11.

[0083] Exemplarily, in the embodiment of the present application, if the output main shaft 31 is rotatably arranged on the mounting base 11 by means of the bearing assembly 33, the bearing assembly 33 generates radial constraint on the output main shaft 31, and the radial constraint of the bearing assembly 33 on the output main shaft 31 can realize the positioning of the output main shaft 31. Since the coaxial constraint of the positioning sleeve 223 on the transmission shaft 222 is based on the output main shaft 31, the positioning of the bearing assembly 33 on the output main shaft 31 can be regarded as the reference positioning for the coaxial constraint.

[0084] Exemplarily, in the embodiment of the present application, the mounting base 11 can further have a bearing support seat 113, and the bearing assembly 33 can be radially limited in the bearing support seat 113, so that the bearing assembly 33 can generate radial constraint on the output main shaft 31 based on the radial limitation in the bearing support seat 113.

[0085] Exemplarily, in the embodiment of the present application, the housing assembly 10 can further comprise an auxiliary support 13, the auxiliary support 13 can have a bearing limiting seat 133, and the auxiliary support 13 can be fixedly arranged on the mounting base 11 so that the bearing limiting seat 133 is in opposite engagement with the bearing support seat 113. Thus, the opposite engagement of the bearing limiting seat 133 with the bearing support seat 113 can radially limit the bearing assembly 33 in the bearing support seat 113.

[0086] Exemplarily, in the embodiments of the present application, the auxiliary bracket 13 can not be limited to the radial limiting of the bearing assembly 33, and the auxiliary bracket 13 can also be used to mount the power supply assembly 40 of the door opener. For example, as shown in the embodiments of the present application, the power supply assembly 40 can include a power conversion device 41 such as a transformer and a power filter device 43 such as a rectifier bridge, the power conversion device 41 and the power filter device 43 are used to provide internal power supply of the door opener based on external power supply, the internal power supply provided by the power conversion device 41 and the power filter device 43 can include the driving motor 21 and the electrical assembly 70 of the door opener, and the power conversion device 41 and the power filter device 43 can be fixedly mounted on the auxiliary bracket 13. In this case, the power supply cable of the driving motor 21 can be led out from the auxiliary bracket 13 and connected to the driving motor 21, and in order to avoid the power supply cable being wound to the output spindle 31, the power supply cable can avoid the output spindle 31 based on the binding of the cable buckle 25. For example, the mounting base 11 can also have a buckle socket 110, and the cable buckle 25 can be inserted into the buckle socket 110 to achieve the binding of the power supply cable of the driving motor 21.

[0087] Exemplarily, in the embodiments of the present application, as described above, the end of the output spindle 31 away from the transmission shaft 222 can be connected to the transmission gear 35, and the output spindle 31 can be drivingly connected to the door leaf 95 through the transmission gear 35, in this case, the bearing assembly 33 can be close to the end of the output spindle 31 where the transmission gear 35 is located (i.e. close to the end of the output spindle 31 where the transmission gear 35 is connected) in the axial direction of the output spindle 31.

[0088] Exemplarily, in the embodiments of the present application, if the transmission gear 35 can be suspended outside the base edge of the mounting base 11, and the bearing assembly 33 can be radially limited in the bearing support seat 113, the bearing support seat 113 can be located at the base edge of the mounting base 11, so that the bearing assembly 33 is close to the end of the output spindle 31 where the transmission gear 35 is located (i.e. close to the end of the output spindle 31 where the transmission gear 35 is connected) in the axial direction of the output spindle 31.

[0089] Exemplarily, in the embodiments of the present application, the output spindle 31 can include a support shaft segment 313 and a docking shaft segment 312, one end of the support shaft segment 313 is coaxially fixedly connected with the transmission gear 35, the docking shaft segment 312 is coaxially fixedly connected at the other end of the support shaft segment 313 which is away from the transmission gear 35 (i.e. towards the transmission module 22), the docking shaft segment 312 is used for transmission connection with the transmission rotating shaft 222, and the bearing assembly 33 can be arranged at the support shaft segment 313 of the output spindle 31 close to the transmission gear 35. In this case, the output spindle 31 can have an annular clamping groove 314 at the boundary between the support shaft segment 313 and the docking shaft segment 312, the annular clamping groove 314 can be arranged with a limiting clamping hoop 34, and the limiting clamping hoop 34 can generate axial limitation to prevent the bearing assembly 33 from being axially deviated to the docking shaft segment 312.

[0090] Exemplarily, in the embodiments of the present application, in order to improve the stability of the radial constraint of the bearing assembly 33 to the output spindle 31, the bearing assembly 33 can include a pair of bearings arranged adjacent in the axial direction of the output spindle 31 (e.g. the support shaft segment 313), and the positioning of the bearing assembly 33 to the output spindle 31 can be achieved cooperatively by the pair of bearings.

[0091] Exemplarily, in the embodiments of the present application, the transmission connection of the output spindle 31 (e.g. the docking shaft segment 312) with the transmission rotating shaft 222 can be normal, or if the transmission module 22 generates structural self-locking to the reverse transmission of the output spindle 31 to the driving motor 21, for example, the transmission module 22 includes a worm gear and a worm, and the reverse transmission of the transmission rotating shaft 222 to drive the worm through the worm gear is locked, then in order to support the manual opening and closing of the door leaf 95, the transmission connection of the output spindle 31 (e.g. the docking shaft segment 312) with the transmission rotating shaft 222 can also be controlled by clutching.

[0092] Exemplarily, in the embodiments of the present application, if the transmission connection of the output spindle 31 (e.g. the docking shaft segment 312) with the transmission rotating shaft 222 needs to be controlled by clutching, the door operator can further include a clutch assembly 50 for selectively transmission connecting the transmission rotating shaft 222 with the output spindle 31 (e.g. the docking shaft segment 312), or disconnecting the transmission connection between the transmission rotating shaft 222 and the output spindle 31 (e.g. the docking shaft segment 312), and the clutch assembly 50 can be carried on the mounting base 11.

[0093] Fig. 6 is a schematic diagram of the clutch switching principle between the output spindle and the transmission module of the door opener in the embodiment of the present application. Referring to Fig. 6, in the embodiment of the present application, the clutch assembly 50 can include a clutch insert 55, the output spindle 31 can have an axial sliding slot 315, and the clutch insert 55 is movably inserted into the axial sliding slot 315 along the axial direction of the output spindle 31; and the transmission spindle 222 can have a clutch slot 225, and the clutch insert 55 can drive connect the transmission spindle 222 and the output spindle 31 (for example, the butt joint shaft segment 312) by the plug-in cooperation with the clutch slot 225, and the clutch insert 55 can disconnect the drive connection between the transmission spindle 222 and the output spindle 31 (for example, the butt joint shaft segment 312) by disengaging from the clutch slot 225.

[0094] Therefore, when the transmission spindle 222 is drive connected with the output spindle 31, the transmission spindle 222 can be driven to rotate synchronously with the output spindle 31 in response to the power output generated by the driving motor 21, and the synchronous rotation of the output spindle 31 following the transmission spindle 222 can be used to drive the door leaf 95 to automatically open and close; and when the drive connection between the output spindle 31 and the transmission spindle 222 is disconnected, the movement of the door leaf 95 is not limited by the structural self-locking of the reverse drive of the transmission module 22, so that the freedom of manual opening and closing of the door leaf 95 is released.

[0095] Exemplarily, in the embodiment of the present application, as described above, the coaxiality constraint of the positioning sleeve 223 of the transmission module 22 to the transmission spindle 222 is used to constrain the coaxiality deviation ΔCoax between the transmission spindle 222 and the output spindle 31 to be less than or equal to the preset deviation threshold, on the basis of which the plug-in cooperation of the clutch insert 55 and the clutch slot 225 can have a cooperation allowance, and the cooperation allowance can be used to adaptively compensate the coaxiality deviation ΔCoax constrained to be less than or equal to the preset deviation threshold.

[0096] Exemplarily, in embodiments of the present application, the clutch slot 225 can have a slot depth in the axial direction of the transmission shaft 222, and the clutch slot 225 can also have a slot length in the first radial direction of the transmission shaft 222 and a slot width in the second radial direction of the transmission shaft 222, the first radial direction and the second radial direction being perpendicular to each other, the slot length of the clutch slot 225 corresponding to the tab width of the clutch tab 55, and the slot width of the clutch slot 225 corresponding to the tab thickness of the clutch tab 55. In this case, the fit allowance can include a translational bias allowance of the clutch tab 55 in the first radial direction (i.e. the tab width direction of the clutch tab 55 and the slot length direction of the clutch slot 225) relative to the clutch slot 225, and / or a clearance fit allowance between the clutch tab 55 and the clutch slot 225 in the second radial direction (i.e. the tab thickness direction of the clutch tab 55 and the slot width direction of the clutch slot 225).

[0097] Exemplarily, in embodiments of the present application, the clutch tab 55 can have a tab end edge 551 for interfacing with the clutch slot 225, wherein: the end edge width of the tab end edge 551 can be greater than the slot length of the clutch slot 225, and the clutch slot 225 extends through the transmission shaft 222 in the first radial direction of the transmission shaft 222, so that the clutch slot 225 can release the radial restriction on the clutch tab 55 (i.e. the tab end edge 551) in the first radial direction of the transmission shaft 222 (i.e. the slot length direction of the clutch slot 225), to provide a translational bias allowance of the clutch tab 55 in the first radial direction (i.e. the tab width direction of the clutch tab 55 and the slot length direction of the clutch slot 225) relative to the clutch slot 225; and / or the end edge thickness of the tab end edge 551 can be less than the slot width of the clutch slot 225 in the second radial direction of the transmission shaft 222, so that a clearance fit between the tab end edge 551 and the clutch slot 225 in the second radial direction of the transmission shaft 222 (i.e. the tab thickness direction of the clutch tab 55 and the slot width direction of the clutch slot 225) can provide a clearance fit allowance between the clutch tab 55 and the clutch slot 225 in the second radial direction (i.e. the tab thickness direction of the clutch tab 55 and the slot width direction of the clutch slot 225).

[0098] As can be seen above, based on the embodiments of the present application, the clutch assembly 50 of the door opener can selectively drive-connect the output spindle 31 with the transmission rotating shaft 222 of the transmission module 22, or disconnect the drive connection between the output spindle 31 and the transmission rotating shaft 222, by means of the clutch tab 55, so as to realize the automatic opening and closing of the door leaf 95 when the output spindle 31 is drive-connected with the transmission rotating shaft 222, or support the manual opening and closing of the door leaf 95 when the drive connection between the output spindle 31 and the transmission rotating shaft 222 is disconnected. Wherein, when the clutch tab 55 is drive-connected with the transmission rotating shaft 222 by means of the plug-in cooperation with the transmission rotating shaft 222, the clutch tab 55 and the transmission rotating shaft 222 can have a cooperation allowance, and the cooperation allowance between the clutch tab 55 and the transmission rotating shaft 222 can adaptively compensate the coaxiality deviation ΔCoax between the output spindle 31 and the transmission rotating shaft 222. Thus, the clutch assembly 50 of the door opener can inhibit the radial excursion of the output spindle 31 during the rotation in response to the power output by means of the compensation of the coaxiality deviation ΔCoax, and further help to improve the stability of the automatic opening and closing of the door leaf 95 in the case of supporting the manual opening and closing of the door leaf 95.

[0099] Exemplarily, in the embodiments of the present application, the transmission rotating shaft 222 can be inserted in the output spindle 31, and the clutch tab 55 can realize the plug-in cooperation with the clutch slot 225 and the disengagement from the clutch slot 225 in the output spindle 31, so as to shorten the overall axial suspension span of the transmission rotating shaft 222 and the output spindle 31 by means of the axial plug-in of the transmission rotating shaft 222 and the output spindle 31, and further help to improve the stability of the transmission rotating shaft 222 and the output spindle 31 when being drive-connected.

[0100] Exemplarily, in the embodiments of the present application, one end of the output spindle 31 away from the transmission rotating shaft 222 can be connected with the transmission gear 35, and the output spindle 31 can be drive-connected with the door leaf 95 through the transmission gear 35, in which case, the bearing assembly 33 can be close to one end of the output spindle 31 where the transmission gear 35 is located (i.e. close to one end of the output spindle 31 where the transmission gear 35 is connected) in the axial direction of the output spindle 31, and the axial sliding groove 315 for the movement of the clutch tab 55 can be located on the side of the bearing assembly 33 towards the transmission rotating shaft 222.

[0101] Exemplarily, in the embodiment of the present application, the output spindle 31 can include a support spindle segment 313 and a docking spindle segment 312, one end of the support spindle segment 313 is coaxially fixedly connected with the transmission gear 35, the docking spindle segment 312 is coaxially fixedly connected at the other end of the support spindle segment 313 which is away from the transmission gear 35 (i.e. towards the transmission module 22), and the docking spindle segment 312 is used for transmission connection with the transmission rotating shaft 222. In this case, the axial sliding slot 315 can be located at the docking spindle segment 312, the transmission rotating shaft 222 can be inserted in the docking spindle segment 312, and the clutching insert piece 55 can realize the plug-in cooperation with the clutching insert slot 225 and the disengagement from the clutching insert slot 225 in the docking spindle segment 312.

[0102] Exemplarily, in the embodiment of the present application, the clutching assembly 50 can further include a clutching reset member 57 (for example, the clutching reset member 57 can include a spring), which can generate an elastic reset force on the clutching insert piece 55 in the axial direction of the output spindle 31, the elastic reset force is used to urge the clutching insert piece 55 to plug-in cooperate with the clutching insert slot 225, and the clutching insert piece 55 is used to disengage from the clutching insert slot 225 against the elastic reset force under the action of an operation holding force generated in response to external operation.

[0103] Exemplarily, in the embodiment of the present application, in order to make the length of the output spindle 31 as short as possible, the clutching reset member 57 can be inserted in the support spindle segment 313 of the output spindle 31 for mounting the bearing assembly 33, i.e. the mounting of the bearing assembly 33 and the clutching reset member 57 in the output spindle 31 can reuse the support spindle segment 313.

[0104] Exemplarily, in the embodiment of the present application, in order to avoid the clutching reset member 57 from disengaging from the clutching insert piece 55, the clutching insert piece 55 can have a clamping flange 557 which can be located at the opposite side of the plug-in end edge 551, and the clamping flange 557 can generate an anti-disengagement constraint for preventing the clutching reset member 57 from deviating from the clutching insert piece 55 by clamping cooperation with the clutching reset member 57.

[0105] Exemplarily, in embodiments of the present application, the clutching tab 55 can have a guide slot 556 extending between the insertion end edge 551 and the clamping flange 557, the output spindle 31 can have a radial pin hole 316 provided in the abutting spindle segment 312, the radial pin hole 316 can be fixed with a limiting guide pin shaft 56 penetrating therethrough, and the limiting guide pin shaft 56 can also be inserted in the guide slot 556 of the clutching tab 55. Thus, the movement of the clutching tab 55 in the axial slot 315 can be limited in the axial direction of the output spindle 31 by the sliding fit of the guide slot 556 and the limiting guide pin shaft 56, and the movement range of the clutching tab 55 in the axial direction of the output spindle 31 can be limited between the slot bottom of the clutching slot 225 and the supporting spindle segment 313 by the limiting fit between the limiting guide pin shaft 56 and the guide slot 556.

[0106] Exemplarily, in embodiments of the present application, the clutching tab 55 can also have a lateral lug 553, the lateral lug 553 of the clutching tab 55 can protrude beyond the axial wall of the output spindle 31 (e.g. the abutting spindle segment 312) in the radial direction of the output spindle 31, and the operation holding force described in the foregoing for overcoming the elastic return force can be applied to the lateral lug 553 of the clutching tab 55.

[0107] Exemplarily, in embodiments of the present application, the clutching assembly 50 can also include a lock cylinder assembly 52 and a displacement assembly 53, the lock cylinder assembly 52 can be used to drive the displacement assembly 53 to have a positional deviation in response to an operation holding force generated by an external operation, and the positional deviation of the displacement assembly 53 is used to cause the clutching tab 55 to disengage from the clutching slot 225 by overcoming the elastic return force, for example, the positional deviation of the displacement assembly 53 can transmit the operation holding force to the clutching tab 55 (e.g. the lateral lug 553). Wherein, the elastic return force mentioned herein can be generated by the clutching return member 57 described in the foregoing, which is used to drive the clutching tab 55 to be in the insertion fit with the clutching slot 225 when the operation holding force disappears, and the insertion fit of the clutching tab 55 with the clutching slot 225 under the driving of the elastic return force can cause the displacement assembly 53 to have a deviation reset in the reverse direction of the positional deviation.

[0108] Fig. 7 is a schematic diagram of the working principle of the lock cylinder assembly in the clutch assembly of the door opener in the embodiment of the present application. Fig. 8 is a schematic diagram of the assembly relationship between the clutch assembly of the door opener in the embodiment of the present application and the mounting base. Please refer to Figs. 7 and 8. In the embodiment of the present application, the lock cylinder assembly 52 can include a lock cylinder drum 522 and a lock cylinder shaft 523. The lock cylinder drum 522 can be rotatably arranged in the mounting base 11. The lock cylinder shaft 523 can be arranged through the lock cylinder drum 522. The lock cylinder shaft 523 is rotationally constrained by the mounting base 11. Thus, the rotation of the lock cylinder drum 522 about its axis can cause the axial movement of the lock cylinder shaft 523 along the axis direction of the lock cylinder drum 522.

[0109] For example, in the embodiment of the present application, the mounting base 11 can have a lock cylinder mounting groove 118. The lock cylinder drum 522 can be rotatably arranged in the lock cylinder mounting groove 118 of the mounting base 11.

[0110] For example, in the embodiment of the present application, the lock cylinder drum 522 can be fixedly arranged in the lock cylinder mounting groove 118 of the mounting base 11 and radially limited by the lock cylinder gland 16 of the mounting base 11. Thus, the lock cylinder drum 522 can be prevented from radially deviating due to the operation holding force generated by external operation.

[0111] For example, in the embodiment of the present application, the lock cylinder drum 522 can be located at the base edge of the mounting base 11. For example, the lock cylinder mounting groove 118 can be located at the base edge of the mounting base 11. Thus, the lock cylinder drum 522 can more easily receive the operation holding force generated by external operation.

[0112] For example, in the embodiment of the present application, the lock cylinder mounting groove 118 can have a lock cylinder exposure opening 115 at the groove end outside the base edge of the mounting base 11. The lock cylinder exposure opening 115 can be detachably arranged with a lock cylinder baffle 15 (shown in Fig. 1). Thus, when it is needed to disconnect the transmission connection between the output spindle 31 and the transmission shaft 222 to manually open and close the door leaf 95, the lock cylinder baffle 15 can be detached. The operation member 51 can be transmissionally connected with the lock cylinder drum 522 through the lock cylinder exposure opening 115. Thus, the operation holding force applied to the lock cylinder drum 522 can be generated by performing external operation on the operation member 51.

[0113] Exemplarily, in the embodiments of the present application, the lock cylinder drum 522 can have a screw key shaft 521 at one end thereof which is directed outwardly from the base edge of the mounting base 11 (e.g. toward the lock cylinder exposure opening 115), the screw key shaft 521 is used for plugging the operation member 51, and an operation holding force generated by performing an external operation on the operation member 51 can be applied to the screw key shaft 521. In this case, the operation member 51 can include a screw key buckle 512 for plugging with the screw key shaft 521 through the lock cylinder exposure opening 115, and the operation member 51 can further include a handle knob 511, so that by applying an external operation (i.e. a screwing operation) on the handle knob 511, the screw key shaft 521 can be driven to rotate synchronously by the screw key buckle 512 to drive the lock cylinder drum 522 to rotate.

[0114] Exemplarily, in the embodiments of the present application, the lock cylinder assembly 52 can further include a rotation-stopping guide pin 526, and the rotation-stopping guide pin 526 can be fixedly arranged on the lock cylinder shaft 523 along a radial direction of the lock cylinder shaft 523, in which case: the mounting base 11 can further have a rotation-stopping guide groove 117, for example, the rotation-stopping guide groove 117 can be located at the groove bottom of the lock cylinder mounting groove 118, the extension direction of the rotation-stopping guide groove 117 can be parallel to the axial direction of the lock cylinder drum 522, the rotation-stopping guide pin 526 can be further inserted into the rotation-stopping guide groove 117, the rotation-stopping guide groove 117 can generate rotation-stopping constraint on the lock cylinder shaft 523 by limiting the rotation-stopping guide pin 526 in the groove width direction, and the sliding fit of the rotation-stopping guide pin 526 and the rotation-stopping guide groove 117 is used for guiding the lock cylinder shaft 523 to axially extend outwardly from the lock cylinder drum 522 or to axially retract inwardly into the lock cylinder drum 522 along the axial direction of the lock cylinder drum 522; the drum wall of the lock cylinder drum 522 can further have a drum spiral groove 525, the rotation-stopping guide pin 526 can be further arranged in the drum spiral groove 525, and the sliding fit of the rotation-stopping guide pin 526 and the drum spiral groove 525 is used for converting the phase shift of the lock cylinder drum 522 in a first rotation direction relative to an initial phase to the axial extension of the lock cylinder shaft 523, and converting the axial retraction of the lock cylinder shaft 523 to the phase reset of the lock cylinder drum 522 in a second rotation direction opposite to the first rotation direction to return to the initial phase.

[0115] Fig. 9 is a schematic view of the engagement state of the clutch assembly of the door opener in the embodiment of the present application when the clutch assembly connects the output spindle and the transmission module in transmission; Fig. 10 is a schematic view of the disengagement state of the clutch assembly of the door opener in the embodiment of the present application when the clutch assembly disconnects the output spindle and the transmission module; please further refer to Fig. 8 and combine Fig. 9 and Fig. 10: the lock cylinder drum 522 can be phase-shifted in the first rotation direction relative to the initial phase in response to the operating holding force, the phase shift of the lock cylinder drum 522 can drive the lock cylinder shaft 523 to axially extend out of the lock cylinder drum 522 in the axial direction of the lock cylinder drum 522, and the axial extension of the lock cylinder shaft 523 can cause the position shift of the displacement assembly 53, so that the position shift of the displacement assembly 53 can transmit the operating holding force to the clutch tab 55 (for example, the lateral lug 553), and then the clutch tab 55 is used to disengage from the clutch slot 225 under the action of the operating holding force generated in response to the external operation, that is, the change from Fig. 9 to Fig. 10 occurs; and when the operating holding force disappears, the elastic return force of the elastic return member 57 on the clutch tab 55 can be transmitted to the displacement assembly 53 through the clutch tab 55 (for example, through the lateral lug 553) to promote the displacement assembly 53 to generate the aforementioned shift reset when the operating holding force disappears, so that the shift reset of the displacement assembly 53 when the operating holding force disappears can drive the lock cylinder shaft 523 to axially retract into the lock cylinder drum 522 in the axial direction of the lock cylinder drum 522, and the axial retraction of the lock cylinder shaft 523 can drive the lock cylinder drum 522 to be phase-reset to the initial phase in the second rotation direction opposite to the first rotation direction, that is, the change from Fig. 10 to Fig. 9 occurs.

[0116] Exemplarily, in the embodiment of the present application, the displacement assembly 53 can avoid the output spindle 31 and the transmission module 22 to avoid the position shift and the shift reset of the displacement assembly 53 causing the output spindle 31 and the transmission module 22 to be axially shifted to increase the coaxiality deviation.
