Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, including the first screw rod 1,1 top of the first screw rod are equipped with and screw handle 11, the first screw rod 1
Bottom end is against the top of mold 6；First screw rod 1 is hinged with multiple claws 3 by screw pair 2；Claw 3 includes the company being fixedly connected
Bar and paw 32, the end of connecting rod and screw pair 2 are hinged, and paw 32 is overlapped on the bottom end of mold 6；Screw pair 2 drives claw 3 vertical
To movement, the first screw rod 1 is fixedly clamped or loosens to mold 6 with the cooperation of claw 3.
To above-mentioned it should be noted that as depicted in figs. 1 and 2, screw pair 2 is arranged on the first screw rod 1, multiple claws 3 are cut with scissors
It connects on screw pair 2, but it is not limited to using articulated manner, as long as meeting claw 3 around claw 3 and screw pair 2
Connecting pin longitudinally upper 180 degree rotation, is hingedly its preferred embodiment；Otic placode 21, claw are particularly set on screw pair 2
3 connecting rod and otic placode 21 hingedly, be equipped on 1 top of the first screw rod and screw handle 11, personnel can be by screwing handle
11 come make the first screw rod 1 rotate, save manpower；The claw 3 at least two being movably connected on screw pair 2, the first screw rod 1
Rotation promote the relative position of the first screw rod 1 and screw pair 2 to change, the paw 32 of claw 3 forms the lower end of mold 6
Longitudinal force, while the first screw rod 1 forms longitudinal force to the top of mold 6, realizes the clamping to mold 6, can be with
Realize and fixation be clamped to multiple positions of mold 6 simultaneously, without by using more set clamping devices respectively to mold 6
Different parts be clamped.
As depicted in figs. 1 and 2, the claw 3 is uniformly arranged in the circumferential direction of screw pair 2；The connecting rod of claw 3 is that bending connects
Bar 31,32 integrally connected of one end and paw of bent connecting rod 31, the other end and screw pair 2 of bent connecting rod 31 are hinged.
Above-mentioned claw 3 is uniformly arranged in the circumferential direction of screw pair 2 it should be noted that in order to promote claw 3 to screw pair 2
On active force reach balance, claw 3 is uniformly arranged in the external circumferential of screw pair 2.Prevent the week when claw 3 in screw pair 2
To not being uniformly arranged, keep claw 3 uneven to the active force on screw pair 2, and then the paw 32 of different claws 3 is to mold 6
Bottom end active force it is uneven, while can also accelerate the abrasion between the first screw rod 1 and screw pair 2, reduce by 1 He of the first screw rod
The service life of screw pair 2.
Connecting rod to above-mentioned claw 3 is bent connecting rod 31 it should be noted that in order to prevent because mold 6 is to claw 3
Connecting rod generates the outer top power in transverse direction, makes paw 32 that can not be overlapped on the bottom end of mold 6.The shape of specific bent connecting rod 31 can
To be the bent connecting rod 31 of arcuation, it is also possible to the bent connecting rod 31 of polyline shaped.
Further, as depicted in figs. 1 and 2,1 bottom end of the first screw rod is equipped with limited block 4, the first screw rod 1 and limited block 4
Top is connected by universal joint；The bottom end of limited block 4 is fixedly connected with the first chassis 5.
To above-mentioned it should be noted that the bulb of universal joint is fixedly connected on the bottom end of the first screw rod 1, limited block 4
On offer groove compatible with the bulb of universal joint, universal joint is arranged in groove, and the diameter of bulb is greater than
The opening diameter of groove.When the top of mold 6 and the angle of bottom end are not more than 45 degree, universal joint can make the first chassis 5
Bottom end still with the top of mold 6 completely attach to.It is equipped with non-slip texture in the bottom end on the first chassis 5 simultaneously, prevents mold 6 from existing
Movement in transverse direction.
Further, as depicted in figs. 1 and 2, it is connected with flexible rope between limited block 4 and claw 3, when 2 band of screw pair
Flexible rope is tightened when dynamic claw 3 moves up, the flexible rope relaxation when screw pair 2 drives claw 3 to move down.
To above-mentioned it should be noted that flexible rope can be wirerope or iron chains, when screw pair 2 drive claw 3 to
Flexible rope, which is tightened, when upper mobile promotes claw close to mold center, keeps claw more stable to the clamping action of mold.When
Flexible rope relaxation when screw pair 2 drives claw 3 to move down, while claw reduces the active force of mold.
It advanced optimizes, the auxiliary lock for being locked to 6 top edge of mold is also fixedly connected on limited block 4
Tight device.
To above-mentioned it should be noted that the combination on the first screw rod 1 and the first chassis 5 can only be realized to 6 top center of mold
Locking, in order to preferably to 6 top of mold realize locking effect, so that additional locking devices be arranged.Specific auxiliary
Locking device includes the multiple transverse arms 43 for being fixedly connected on 4 side of limited block, perpendicular to the side of limited block 4, transverse arm 43
Quantity be at least three, four transverse arms 43 of setting of optimization, the section of transverse arm 43 is rectangle；It is opened on each 43 longitudinal direction of transverse arm
Equipped with multiple through-holes, the through-hole of one of them wears the second screw rod 42 on each transverse arm 43, and personnel can be according to 6 top of mold
Second screw rod 42 is threaded through in different through-holes by size decision；The bottom end of each second screw rod 42 is fixedly connected with the second chassis
44, the integrally connected of the second screw rod 42 and the second chassis 44 can be used；It is also arranged on each second screw rod 42 and second
The compatible tightening nut 45 of screw rod 42, tightening nut 45 is between transverse arm 43 and second base, by rotating tightening nut
45 realize the locking to 6 tip edge position of mold, and transverse arm 43 is existed by longitudinal upper top power in order to enhance transverse arm 43 at this time
The stability under the action of power is pushed up on this, and floor 41 is added between transverse arm 43 and limited block 4.
The above embodiments are merely examples for clarifying the description, and does not limit the embodiments.For institute
For the those of ordinary skill in category field, other various forms of variations or change can also be made on the basis of the above description
It is dynamic.There is no necessity and possibility to exhaust all the enbodiments.And obvious variation extended from this or change
It moves among still in the protection scope of the utility model.
