The sliding block 11 is clamped by the card slot 12 of 13 lower surface of latch plate with 13 lower surface of latch plate, the latch plate 13 Both sides are fixedly connected with fixed plate 19, and the latch plate 13 is equipped with baffle 15, and the latch plate 13 passes through spring 14 and baffle 15 connections, 15 both sides of baffle slidably connect a L riser 161, and two L risers 161 are respectively fixedly connected with One end of two clamping supports 16, and 16 side of clamping support is provided with half slot, described 161 one end of L risers is provided with slide bar groove 17, described Slide bar 18 is slidably connected in slide bar groove 17, one end of the slide bar 18 is fixedly connected on the inner side of fixed plate 19, the clamping support 16 one end away from slide bar groove 17 are fixedly connected with release link 20, and the release link 20 runs through and extends fixed plate 19, and multiple Fastening spring 21 is socketed with outside the bar 20 of position, by the pulling force of fastening spring 21, pulls clamping support 16,21 both ends of fastening spring Be separately fixed on fixed plate 19 and clamping support 16, limit clamping support 16 can only horizontal movement, 19 upper end of fixed plate is fixed It is connected with rack for test tube 22.

Specifically, the pawl 9 back and forth horizontally and vertical reciprocal 10 both sides of pawl are equipped with two draw runners 23, and two draw runners The distance between 23 match with horizontal reciprocating pawl 9, vertical reciprocal 10 size of pawl, the reciprocal pawl 9 of limit levels and vertical reciprocal pawl 10 mobile route, the draw runner 23 are fixedly connected on 1 upper surface of bottom plate.

Specifically, 3 radius of semicircle wheel is round take turns 7 radiuses twice, and semicircle wheel 3 rotates half-turn, 7 rotation one of circle wheel Circle.

Specifically, the length of the slide bar 18 is more than the ultimate range between L risers 161 and fixed plate 19, ensures that L is erected When plate 161 and clamping support 16 move, the slide bar groove 17 that 161 one end of L risers is provided with is without departing from slide bar 18.

Operation principle：Test tube is put into rack for test tube 22, through clamping support 16, is in contact with baffle 15, baffle 15 is transported downwards Dynamic, two L risers 161 being connected at this time with 15 both sides of baffle are disconnected, and by the compression stress of fastening spring 21, are made and two Two clamping supports 16 that a L risers 161 are fixed are slided to close to the direction of fastening spring 21, so as to clamp test tube, open motor 5, motor 5 drives two semicircle wheels 3 to rotate, and semicircle wheel 3 and circle 7 engagement rotations of wheel, the circle wheel 7 of 11 horizontal direction of sliding block drive phase The curved bar 8 of connection moves, and curved bar 8 drives horizontal reciprocating pawl 9 horizontal reciprocating movement between draw runner 23, while pawl 9 back and forth horizontally Level is done together with the fixed plate 19 that the sliding block 11 of connection drives latch plate 13 and latch plate 13 to connect by the clamping with card slot 12 Move back and forth, the semicircle wheel 3 of 11 vertical direction of sliding block is not engaged with circle wheel 7 at this time；

When the semicircle wheel 3 of 11 horizontal direction of sliding block rotates half-turn, circle wheel 7 rotates one and encloses, and the half of 11 horizontal direction of sliding block Circle wheel 3 departs from circle wheel 7, and semicircle wheel 3 and circle 7 engagement rotations of wheel, the circle wheel 7 of 11 vertical direction of sliding block drive the curved bar 8 being connected Mobile, curved bar 8 drives vertical reciprocal pawl 10 to be moved back and forth vertically between draw runner 23, while the sliding block that vertical reciprocal pawl 10 connects Vertical reciprocating motion is done together with 11 fixed plates 19 for driving latch plate 13 and latch plate 13 to connect by the clamping with card slot 12, when When the semicircle wheel 3 of 11 vertical direction of sliding block rotates half-turn, circle wheel 7 rotates a circle, and the semicircle wheel 3 of 11 vertical direction of sliding block departs from circle Wheel 7, the fixed plate 19 that such repetitive operation can connect the latch plate 13 of the drive of sliding block 11 and latch plate 13 continuously do level Reciprocal and vertical reciprocal movement, so that reaching makes the well-mixed purpose of experimental subjects in rack for test tube 22, when completing to mix, Motor 5 is powered off, presses release link 20, release link 20 promotes clamping support 16, and clamping support 16 departs from the contact with test tube, and L Riser 161 is moved to both sides, is no longer propped up baffle 15, is moved up with baffle 15 under action from the spring 14, at this time baffle 15 On test tube can move up, can be taken off the experimental subjects that has been sufficiently mixed at this time.

While there has been shown and described that the embodiment of the utility model, for the ordinary skill in the art, It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from the principle of the utility model and spirit, repaiied Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
