During the driving member with protrusion 31 turns to protrusion 31 and progressively disengages cooperating recesses 411, elasticity is supported Top component 41 is gradually compressed, and there is the driving member of protrusion 31 to switch to unlocked state from lock state for this.When this is with protrusion During 31 driving member is rotated towards the direction for being detached from cooperating recesses 411, since cooperating recesses 411 are to be arranged to support in elasticity On top component 41, protrusion 31, which squeezes elasticity and supports component 41 elasticity is made to support component 41, to be compressed, and elastic-restoring force is increasingly Greatly, that is to say, that elasticity supports component 41 and protrusion 31 is hindered to be detached from cooperating recesses 411, and protrusion 31 is needed by bigger external force Lower to be detached from cooperating recesses 411, when external force is sufficiently large, protrusion 31 is detached from from cooperating recesses 411, when with protrusion 31 Driving member continuation rotates under biggish external force, this there is elasticity suffered by the driving member of protrusion 31 to support component 41 applied The elastic resistance added is smaller and smaller, and there is the driving member of protrusion 31 can be rotated for this, and the first horn 10 and the second horn 20 are in turn It is able to rotate.

During the driving member with protrusion 31 turns to protrusion 31 and progresses into cooperating recesses 31, elasticity is supported Component 41 is gradually released, and there is the driving member of protrusion 31 gradually to switch to lock state from unlocked state for this.With protrusion 31 driving member during being transferred to cooperating recesses 31, support component 41 and be gradually released, and elasticity supports component 41 by elasticity Be conducive to protrusion 31 to enter in cooperating recesses 31, be transferred to completely in protrusion 31 into cooperating recesses 31 and cooperation is produced in protrusion 31 Before recess portion 31, elasticity supports component 41 and is in the state being released, and in this process, protrusion 31 can be in cooperating recesses 31 Smooth rotation, therefore, in this process, this has the driving member of protrusion 31 in the unlocked state, the first horn 10 and the second machine Arm 20 can smooth rotation, until protrusion 31 is transferred to reaches lock state into cooperating recesses 31 completely.

The present embodiment by elasticity support on component 41 be arranged with protrusion 31 cooperate cooperating recesses 411, so as to Locking effect is further increased, the stability after improving locking.

Further, as shown in Figure 3 and Figure 4, the protrusion 31 in the present embodiment can be along the transmission where being parallel to itself The pivot center direction of part outwardly protrudes.

Protrusion 31 on one driving member may include it is multiple, protrusion is also formed with multiple recess portions 32 on 41 place end face, Multiple protrusions 31 and 32 continuous arrangement of recess portion form wavy end face W1.Equal cambered surface between each adjacent protrusion 31 and recess portion 32 Transition.Elasticity supports the wavy mating surface W2 being formed on component 41 for cooperating with wavy end face.State as shown in Figure 4 Under, wavy end face W1 and wavy mating surface W2 cooperate, with during the driving member with protrusion 31 rotates counterclockwise, bullet Property supports component 41 and gradually reduces, and hinders the driving member with protrusion 31 to rotate, can make the first horn 10 to a certain extent Current location is kept with the second horn 20.When continuing to go into overdrive to make to have the driving member of protrusion 31 to turn over wavy mating surface W2 Highest point after, elasticity supports component 41 and is gradually recovered the contact surface that deformation makes wavy end face W1 Yu wavy mating surface W2 Be conducive to rotate, when the driving member with protrusion 31 is rotated to the minimum position of wavy mating surface W2, will repeat to enter resistance Hinder the stage of rotation, that is, enters lock state.

By the cooperation of wavy end face W1 and wavy mating surface W2, enable entire synchronizing device 30 in multiple rotations Enter lock state under gyration, that is, the first horn 10 and the second horn 20 can be enabled in multiple and different angle states Lower and then lock state.

As shown in Figure 3 and Figure 4, it is preferred that it may include that the rigidity for cooperating with protrusion 31 is applied that elasticity, which supports component 41, Power part 41a, and the elastic element 41b being set between rigid force-applying piece 41a and mounting base 50.Elastic element 41b can be Axial elasticity part, concretely axial stretching spring, elastic element 41b can be fixedly connected with one end with mounting base 50, the other end It is fixedly connected with rigid force-applying piece 41a.It is, of course, also possible to be, elastic element 41b can be exerted a force with one end and mounting base 50 or rigidity Part 41a is fixedly connected, and the other end of elastic element 41b is abutted with rigidity force-applying piece 41a or mounting base 50.

The present embodiment provides elastic resistance by elastic element 41b, and provides by rigidity force-applying piece 41a and have protrusion The contact surface of 31 driving member, structure is simple, and function-stable.
