Described snap close slice is two, and two snap close slices link together by bearing pin and stop bit sheet three.

It also comprises two cramps, combines by the tightening pin between described two cramps.

It also comprises handle, and the joint of described handle and described rotating shaft is 3/4ths empty annulus, and the little shaft end of described rotating shaft is a semicircle.

The relative prior art of the utility model has following advantage:

1, locks adjustable range accurately;

2, small size can provide big coupling mechanism force;

3, action is accurately accurate;

4, simple to operation.

Embodiment

Describe the utility model by the following examples, should be noted that, cited embodiment should not understand the restriction to invention.

As shown in the figure: present embodiment is with a kind of locking device, and it comprises snap close slice 1, rotating shaft 6, stop bit sheet 3, banking stop 4, lock shaft 5, and described rotating shaft 6 is eccentric shafts 61, and the little axle 62 of described rotating shaft is a rotatingshaft; Described snap close slice 1 one ends are porose, and the other end is a snap close, and the eccentric macro-axis 61 of described rotating shaft 6 connects with the borehole jack of described snap close slice 1 one ends, and the snap close of described snap close slice 1 and described lock shaft 5 adapt, and described snap close slice 1 is connected with described stop bit sheet 3 by bearing pin 2; Described banking stop 4 centers are circular hole, portion's circular hole has a projection 43 within it, described banking stop is with two projections 41 outward, 42, the eccentric macro-axis 61 of described rotating shaft 6 has a groove that adapts with described banking stop inner process 43, and described banking stop 4 utilizes the projection 43 of inner circular to be fixed on the eccentric macro-axis 61 of described rotating shaft; Described stop bit sheet 3 has the recess that adapts with described banking stop 4

outer processes

41,42.

Described snap close slice 1 is two, and two snap close slices 1 link together with stop bit sheet three by bearing pin 2.

It also comprises two cramps 8, combines by tightening pin 9 between described two cramps 8.

It also comprises handle 10, and described handle 10 is 3/4ths empty annulus with the joint of described rotating shaft 6, and little axle 62 ends of described rotating shaft are semicircle.

Two snap close slices 1 of present embodiment link together with stop bit sheet 3 threes by bearing pin 2, and banking stop 4 utilizes the square protrusion 43 (Fig. 3) of inner circular to be installed on rotating shaft 6 big circumferences; Above-mentionedly between two cramps 8, combine by tightening pin 9; Handle 10 usefulness M3 screws are installed in the rotating shaft.(Fig. 1)

This device action process:

1, the centre distance between rotating shaft 6 and the lock shaft 5 is changeless, and rotating shaft 6 is eccentric shafts, and the little axle 62 of rotating shaft is a rotatingshaft, and eccentric macro-axis 61 is connected with snap close slice 1, banking stop 4.Be shown initial position as Fig. 2, rotating shaft 6 and lock shaft 5 breaks away from, and when rotating shaft 6 as the rotation of figure direction, rotating shaft 6 drives banking stops 4 by eccentric macro-axis 61 and rotates, and the projection 41 (Fig. 3) of banking stop 4 drives stop bit sheet 3 and rotates, and stop bit sheet 3 drives snap close slices 1 rotation.

2, rotate gradually when spending by direction as shown when rotating shaft 6 near 90, stop bit sheet 3 falling on the lock shaft 5 slowly, lock shaft 5 is up lifting stop bit sheet 3 slowly simultaneously, like this groove on the disengaging stop bit sheet 3 understood slowly of the projection 41 of banking stop 4; When being screwed into 90 when spending, lock shaft 5 lifts stop bit sheet 3 fully, and snap close slice 1 rides on lock shaft 5 axis, and snap close slice 1 stops turn, and the projection 1 of banking stop breaks away from the groove on the stop bit sheet fully, so rotating shaft 6 and banking stop 4 can continue rotation; Rotating shaft 6 continues by the direction as shown turn, snap close slice 1 is because of riding on the lock shaft 5, because rotating shaft 6 is an eccentric shaft, snap close slice 1 can be from right toward left movement on diagram, when rotating shaft turns over 90 when spending, the hook-type groove of snap close slice 1 can collude on lock shaft 5, and the sharp projection of stop bit sheet 3 can tightly be stuck on the projection 42 of banking stop 4, so just finishes locking action.The locking adjustable range of (as Fig. 3) this mechanism just in time is the little axle of rotating shaft and the twice of eccentric shaft centre distance.

3, when direction as shown rotation (opposite with the locking direction) was pressed in rotating shaft 6, snap close slice 1 is motion from left to right, the hook groove meeting release lock mandrel 5 of snap close slice 1, and the projection 42 of banking stop 4 breaks away from stop bit sheets 3 simultaneously; Turn over 90 nearly when spending, the projection 41 of banking stop 4 can link to each other with the groove of stop bit sheet 3 gradually, simultaneously because the moving of snap close slice 1, can make that lock shaft 5 stop bit sheet 3 is stirred gradually is past left-handed; Be screwed into 90 when spending, the projection 41 of banking stop 4 cooperates fully with the groove of stop bit sheet 3, and banking stop 4 has just blocked stop bit sheet 3.When rotating shaft 6 continued rotation, snap close slice 1, stop bit sheet 3 will rotate with banking stop 4 rotating shafts, so just finish and unclamp action (Fig. 4).

3/4ths annulus (Fig. 5) is removed in the handle 10 of this device and the place that is connected of rotating shaft 6, falls semicircle (Fig. 6) at little axle 62 Bottomings of rotating shaft 6, and handle 10 is with after rotating shaft 6 is connected like this, and handle 10 is 90 rotation spaces of spending on little.When locking state, the length direction of handle 10 is (Fig. 7) straight down.

Obviously; foregoing is just in order to illustrate characteristics of the present utility model; and be not to restriction of the present utility model, the variation that the those of ordinary skill in relevant technologies field is made in the corresponding techniques field according to the utility model should belong to protection category of the present utility model.
