In one example, as shown in fig. 7, hand control device further includes second bearing, such as deep-groove ball second bearing.
The cap portion 22 of shaft shoulder bolt is located in main part 11.Second bearing is set in the bar portion 23 of shaft shoulder bolt, such as smooth circle
On column, and form interference connection.
Bar portion 23 is pierced by from main part 11, and the end of bar portion 23 is fastened in rotation section 12 by nut 21.In bar portion
Bracket 24 is arranged with outside 23.Bracket 24 is between cap portion 22 and main part 11.In the position shape around bar portion 23 of bracket 24
Circlewise lug boss 25.Annular projection portion 25 and the end face of the inner ring 28 of second bearing offset.Due to the original of shaft shoulder bolt fastening
Cause, therefore extruding force is formed between annular projection portion 25 and inner ring 28.Bracket 24 is between cap portion 22 and main part 11 and cap portion
Support is formed between 22 and second bearing, this makes the position of second bearing and the position of shaft shoulder bolt more constant.
In addition, annular projection portion 25 offsets with inner ring 28, therefore inner ring 28 can be more efficiently prevented from and rotated relative to bar portion 23.
In addition, annular projection portion 25 will not outer ring 29 to second bearing form interference.
In one example, as shown in fig. 7, rotation section 12 includes department of assembly 31 and detachably connected with department of assembly 31
Fixed plate 26.For example, department of assembly 31 is for installing various interactive operation devices.Fixed plate 26 is located at the lower section of department of assembly 31, and
It the modes such as is bolted, is clamped, bonding to connect with department of assembly 31.
Fixed plate 26 has through-hole 27.Bar portion 23 is passed through from through-hole 27.Nut 21 is located at the inside of fixed plate 26.Fixed plate
The end face of the outer ring 29 at 26 position and second bearing around through-hole 27 offsets.Due to shaft shoulder bolt fastening, thus it is solid
Extruding force is formed between the position and outer ring 29 around through-hole 27 of fixed board 26, is turned so that fixed plate 26 is synchronous with outer ring 29
It is dynamic.The position around through-hole 27 of fixed plate 26, which will not be formed inner ring 28, interferes.
In one example, as shown in fig. 7, the position around through-hole 27 in fixed plate 26 is additionally provided with annular wall 30.
Annular wall 30 is located at the outside of fixed plate 26.Second bearing be located at that annular wall 30 surrounds intracavitary and connect with 30 interference of annular wall
It connects.In this way, fixed plate 26 and outer ring 29 can more effectively be made to rotate synchronously.
Fig. 5 is the schematic diagram according to the hand control device of the lock state of one embodiment of the disclosure.Fig. 6 is basis
The schematic diagram of the hand control device of the unlocked state of one embodiment of the disclosure.
As seen in figs. 5-6, in this example embodiment, the multiple teeth in rotational direction arranged are provided on rotation section 12.Such as
Multiple gear mutations are at gear 19.In locking, fixed device is configured between at least one tooth or adjacent tooth
Gap forms clamping.This structure keeps the locking of fixed device stronger.
In one example, as seen in figs. 5-6, guide part is provided in main part 11.Guide part is for guiding fixation
Device.For example, guide part is to protrude from the intracorporal boss 20 of shell.Fixed device can be slided along main part 11.For example, fixed device
Entirety it is in a strip shape, including extension 16, the salient point 17 positioned at one end of extension 16 and the other end positioned at extension 16
Clicking section 15.Salient point 17 is to shell internal projection, and clicking section 15 is to shell outer lug.Salient point 17 is opposite with tooth.In extension 16
The end of the side opposite with salient point 17 forms inclined-plane or cambered surface 32.Inclined-plane or cambered surface 32 and guide part (for example, boss 20) phase
Cooperation.
Sliding slot is provided on shell.Wall portion of the sliding slot through shell.Clicking section 15 is located in sliding slot, and can be along the chute
Sliding.For example, the extending direction of sliding slot is parallel to the rotation direction of rotation section 12.Clicking section 15 is slided along the chute, to drive
Salient point 17 is mobile.
As shown in figure 5, guide part, which pushes, to be fixed when fixed device is slided to locking direction (for example, slid clockwise)
At least local motion of device, so that the gap between fixed device and at least one tooth or adjacent tooth forms and is clamped.
In locking, clicking section 15 is mobile clockwise.The inclined-plane or cambered surface 32 are slided along boss 20, to make 17 court of salient point
It is mobile to tooth.Due to inclined-plane or the guiding role of cambered surface 32, boss 20 will push salient point 17 to close to the movement of the direction of gear 19.
Elastic deformation occurs for extension 16.Finally, the gap between salient point 17 and at least one tooth or adjacent tooth forms clamping.Turn
Dynamic portion 12 is fixed device locking.
As shown in fig. 6, in unlock, clicking section 15, which is reversed, stirs (for example, stirring counterclockwise), so that fixed device is inverse
Hour hands rotation.Boss 20 gradually releases the guiding on inclined-plane or cambered surface 32.The elastic deformation of extension 16 gradually returns back to initially
State, so that salient point 17 is separated with gear 19.Fixed device releases the locking to rotation section 12.
In this example embodiment, the locking and unlocking operation of rotation section 12 is very easy.
In other examples, the extending direction of sliding slot and the rotation direction of rotation section 12 are not parallel, as long as being able to guide fixation
Device sliding, to carry out locking and unlocking.
In other examples, rotation section 12 and fixed device form ratchet and pawl arrangement.Spine is provided on rotation section 12
Wheel.Fixed device includes pawl.Ratchet and pawl is arranged on shell.Pawl is capable of forming to the unidirectional of rotation section 12
Locking.In this example embodiment, rotation section 12 can be rotated along one direction, angle, position so as to adjust interactive operation device.
It is also possible that rotation section 12 is connect by damping unit with main part 11.Damping unit includes damping shaft and damping
It covers, one in the two connect with rotation section 12, another connect with the shell of main part 11.Damping shaft and damping sleeve being capable of shapes
At damping force.The damping force is capable of fixing the angle of rotation section 12, position.In this example embodiment, damping unit can be used as being used for
The device of connection is but also as fixed device.
