Another in 334b and the second joint portion 21 includes at least one locking tooth n, and each locking tooth n is suitable for and at least two
The lock groove m is engaged so that second joint portion 21 and the first joint portion 334b are adapted at least in two engagements
Engagement position.Such as first the end face of joint portion 334b be equipped with lock groove m, the end face at the second joint portion 21 is equipped with locking tooth n；Or
Person, the end face at the second joint portion 21 are equipped with lock groove m, and the end face of the first joint portion 334b is equipped with locking tooth n.Slot is used as a result,
The mode of tooth cooperation realizes the connection of clutch part and power output member, is not only simple in structure compact, and facilitates processing.
Only with the first joint portion 334b include below locking tooth m, the second joint portion 21 include make for lock groove n it is further
Ground explanation.
Circumferentially evenly-spaced arrangement, multiple locking tooth n are uniform along the circumferential direction of the first joint portion 334b by multiple lock groove m
Arranged spaced apart, lock groove m, the number of locking tooth n are identical, for example lock groove m, locking tooth n are four.Do not considering to process
In the case where error, the angle of the middle line of two adjacent lock groove m is 90 °, in original state, multiple locking tooth n with it is multiple
Lock groove m is engaged correspondingly, when the first joint portion 334b turns to some locking tooth n and phase relative to the second joint portion 21
When adjacent another lock groove m is engaged, the rotation of mobile terminal can be realized.
Each locking tooth n is suitable for being engaged at least two lock groove m so that clutch part 20 is adapted at least to power output member
It is engaged in two bonding stations.For example some locking tooth n, locking tooth n can be engaged with two lock groove m, the two
Angle between lock groove m is the angle for indicating clutch part 20 and rotating relative to power output member.
As shown in figure 5, lock groove m includes multiple groups, every group includes multiple lock groove m, difference group lock groove m along week
To being staggered, the first joint portion 334b and when the bonding station engagement wherein of the second joint portion 21, multiple locking tooth n with
Wherein one group of multiple lock groove m are corresponded, and the first joint portion 334b and the second joint portion 21 turn to another engagement position
When setting, multiple locking tooth n and another group of multiple lock groove m are corresponded, wherein mutual corresponding two in two groups of lock groove m
The angle of the axis of a lock groove m is 90 °.
The group number of lock groove m can be corresponded with the position number of display terminal, for example display terminal includes horizontal/vertical screen
When two positions, lock groove m be 2 groups, by lock groove m include two groups for, every group include three circumferentially uniform intervals open up
The lock groove m set, lock groove m described in two groups is circumferentially staggered, for example first group of the two sides each lock groove m are respectively provided with one
A second group of lock groove m, in this way in each rotation process, each locking tooth n only need to be embedded in another from a lock groove m
Lock groove m, will not fall into non-targeted lock groove m during rotation, first group of this lock groove m and second group the two
One angle in lock groove m is 90 °, another in first group of this lock groove m and second group of the two lock grooves m
A angle is 30 °, and locking tooth n includes three, three locking tooth n circumferentially evenly-spaced setting, as these three locking tooths n
The rotation of display terminal can be realized when cooperating from different groups of lock groove m.
Lock groove m and locking tooth n all has arc section, and the root width of locking tooth n is greater than the top of locking tooth n
Width, the width of lock groove m open end are greater than the width of the bottom lock groove m, and the width of locking tooth n gradually becomes from root to top
It is small.
When the arcuate flanks of locking tooth n and the curved wall of lock groove m compress, clutch part 20, power output member are (such as attached
It is shown in Fig. 3 334) between can transmit torque；Torque between the first joint portion 334b, the second joint portion 21, which is greater than, to be pre-tightened
When power, the arcuate flanks of locking tooth n occur to slide and be detached from relatively with the curved wall of lock groove m, and locking tooth n slides into another
A lock groove m realizes the rotation of display terminal.
Since arc lock groove m and arc locking tooth n is arranged, so that clutch part 20 and power output member are by large torque
When being detached from respect to sliding by arcwall face, be not susceptible to stuck situation.After lock groove m, locking tooth n are detached from, arc
The locking tooth n of shape is slided along the end face at the second joint portion 21, the frictional force between the first joint portion 334b, the second joint portion 21
It is small, convenient for sliding into next bonding station rapidly, it is not easy stuck.
Lock groove m and locking tooth n is the fan annular concentric with the first joint portion 334b or the second joint portion 21.Also

Central angle be less than the root locking tooth n fan annular central angle, when clutch part 20 is engaged with power output member, locking tooth n
It is related with the circumferentially aligned position of lock groove m to the occlusal position of lock groove m with locking tooth n.
It is understood that ideally (mismachining tolerance for not considering locking tooth and lock groove), each locking tooth n's
Two sides equal-height position is compressed with the two sides of the open end of lock groove m edge respectively；Due to mismachining tolerance, such as two adjacent lockings
The angle of tooth n is not equal to 90 °, and the width of each locking tooth n differs, and part locking tooth n may be unilateral with corresponding lock groove m
It compresses, at least side of locking tooth n is compressed with the respective side of lock groove m so that locking tooth n is engaged with lock groove m.
That is, passing through the locking tooth n and lock groove m of setting above structure form, it is ensured that each locking tooth n is equal
It is engaged with corresponding lock groove m, and in display terminal actual rotation angle and design angle there are when certain error, each locking
Tooth n keeps being engaged with corresponding lock groove m, prevents the feelings that part locking tooth n is engaged with corresponding lock groove m void
A part of condition, another aspect locking tooth is engaged with lock groove m, skids off lock groove m convenient for locking tooth when manual operation.
The depth of lock groove m is less than the height of locking tooth n, and the intensity at such second joint portion 21 is big.
As shown in figure 5, lock groove m and locking tooth n all have it is concentric with the first joint portion 334b or the second joint portion 21
Fan ring section.That is, the width of lock groove m radially becomes larger from inside to outside, the width of locking tooth n radially from
It becomes larger from inside to outside.It is understood that the first joint portion 334b, the second joint portion 21 transmitting torque when, outer end by
Torque it is big, the intensity of outer end can be enhanced by the way that above structure is arranged, prevent from being broken.
