Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the expanded view of fixed pan cam.
Fig. 3 is the expanded view of free cheek cam.
Fig. 4 is the structural representation of toothed surface.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, including left compact heap 1, connecting pin I 2, left latch segment 3, spring 4, universal driving shaft 6, spring 16, right lock
Tight block 15, right compact heap 9, adjusting washer 10, free cheek cam 12 and fixed pan cam 13；Left compact heap 1 and universal driving shaft 6
Left end be fixedly connected by connecting pin I 2.Left latch segment 3 is sleeved on universal driving shaft 6, is set close to left compact heap 1, described
Spring 4 is sleeved on universal driving shaft 6, is set close to left compact heap 1, positioned at the left right side of compact heap 1.Described spring 16 is sleeved on connection
On moving axis 6, set close to the right right side of compact heap 9, middle part is provided with spacing keyway on universal driving shaft 6.
Described fixed pan cam 13 is fixedly mounted on the right-hand member of universal driving shaft 6 by connecting pin II 14, and free cheek is convex
Wheel 12 is arranged on universal driving shaft 6, is set positioned at the left side of fixed pan cam 13, free cheek cam, fixed pan cam are adopted
It is the self-locking plane cam worked in coordination.Correspond to free cheek cam 12 on universal driving shaft 6 and be provided with circumferential groove, activity
Plane cam 12 is provided with stop screw II 11, and the inner of stop screw II 11 is placed in groove, free cheek cam 12
Side is provided with handle 8.Under the effect of stop screw II 11, the anglec of rotation of free cheek cam 12 is limited, it is therefore prevented that living
Dynamic plane cam 12, fixed pan cam 13 during the locking because exert oneself it is excessive be disengaged from face peak, lose locking
Effect.
On described universal driving shaft 6 right latch segment is from left to right sequentially provided between left latch segment 3 and free cheek cam 12
15th, right compact heap 9 and adjusting washer 10.The left latch segment 3 and the contact surface and right compact heap 15 of left compact heap 1 and right locking
The contact surface of block 9 is arc toothed face.The utility model make use of the method for arc toothed dedendum strength and Tooth friction force to replace
The method for producing frictional force for common plane contact fitting, improve the reliability of locking.As the gap between tooth becomes
Small, the final intermeshing flank of tooth is bonded to each other and compressed, arranging density and the tooth form height of tooth can according to left latch segment 3 and
Right latch segment 15 does corresponding adjustment with the positioning precision of body 5, to ensure the intensity of tooth root, ensures the reliable of locking
Property.Left latch segment 3 can both use with right latch segment 15 such as two individual parts of making in the present embodiment, can also be combined into
Used for an entirety.
