Amount.
Described first there are two being opened up as shown in Fig. 1,3,4, on the two side of realizing middle limiting frame 20 described in the present embodiment
210, two second skewed slots 220 of skewed slot, height of first skewed slot, 210 and second skewed slot 220 along realizing middle limiting frame 20
Direction arranges up and down, two first skewed slots, 210, two second skewed slots 220 of the same side respectively along and the screw rod
The parallel direction arranged for interval of 10 extending directions, and first skewed slot 210, the second skewed slot 220 are square shoot, the present embodiment
In the first skewed slot 210, the second skewed slot 220 use rectangle skewed slot, first bolt 60, the second bolt 70 be square pin.In i.e.
Between there are four first bolt, 60, two second bolts of the second skewed slot 220, two of the first skewed slot 210, four in total on limitting casing 20
70, two the first skewed slots 210 per side are located at the top of two the second skewed slots 220, the both ends difference of every first bolt 60
In two the first skewed slots 210 opposite positioned at 20 two side of realizing middle limiting frame, and the both ends of every first bolt 60 respectively with it is upper
The two side of elevator 40 is fixedly connected, and it is opposite that the both ends of every second bolt 70 are located at 20 two side of realizing middle limiting frame
In two the second skewed slots 220, and the both ends of every second bolt 70 are fixedly connected with the two side of lower elevator 50 respectively, in this way
Two first bolts 60 are moved along the first corresponding skewed slot 210 simultaneously, drive the upper elevator 40 being attached thereto rise or
Person declines, and two second bolts 70 are moved along the second corresponding skewed slot 220 simultaneously, drive the lower elevator 50 being attached thereto
Decline or rise, movement is more stable, and first skewed slot 210, the second skewed slot 220 are square shoot, first bolt
60, the second bolt 70 is square pin, and the first bolt 60, the second bolt 70 is avoided to turn in the first skewed slot 210, the second skewed slot 220
It is dynamic, further increase the stability of its movement.According to use demand, can also be set simultaneously on the two side of the realizing middle limiting frame 20
Setting three, either four first skewed slots 210, the second skewed slot 220 are correspondingly arranged three or four the first bolts 60, second
Bolt 70.
As shown in figures 1 to 6, screw rod 10 described in the present embodiment includes the thread segment 110 being connected and linkage section 120, the company
Connect section 120 close to thread segment 110 rod segment be equipped with around its axial line annular groove 122, the thread segment 110 with it is described in
Between limitting casing 20 be threadedly coupled, the lower elevator 50 close to the end face of screw rod 10 be equipped with opening U-shaped through-hole 530, institute
It states U-shaped through-hole 530 to match with the annular groove 122, the linkage section 120 passes through the annular groove 122 and the lower liter
Drop block 50 is rotatably assorted and is limited on the lower elevator 50.The thread segment 110 stretches into realizing middle limiting frame 20 and it
It is threadedly coupled, the linkage section 120 stretches out the lower elevator 50 and is limited in lower elevator 50 by annular groove 122
On, linkage section 120 is rotated by tool, thread segment 110 is driven to rotate, screw rod 10 is limited on lower elevator 50,
Elevator 50 is descended not to be moved forward and backward relatively, the realizing middle limiting frame 20 being threadedly coupled with screw rod 10 is moved forward and backward with respect to screw rod 10.
In the present embodiment, by the cooperation of annular groove 122 of U-shaped through-hole 530 and screw rod 10 on lower elevator 50, screw rod 10 is limited
On lower elevator 50, for the opening direction of the U-shaped through-hole 530 towards the upper elevator 40, i.e., the described screw rod 10 is logical from U-shaped
The opening in hole 530 is caught in U-shaped through-hole 530, and the two side of annular groove 122 is located at the both sides of U-shaped through-hole 530, limitation
The movement of 10 axial direction of screw rod.According to actual demand, other modes can also be used to limit screw rod 10 in the lower lifting
On block 50, the through-hole stretched out for screw rod 10 is set such as on lower elevator 50, is respectively set not on the screw rod 10 of through-hole both sides
The backing pin that screw rod 10 rotates is influenced, limitation screw rod 10 in axial direction moves.According to use demand, screw rod 10 can also be used
Aforesaid way limits on upper elevator 40.
As shown in Fig. 1,5,6, the rod segment that the linkage section 120 stretches out the lower elevator 50 is in non-cylindrical, the U-shaped
Through-hole 530 is the first U-shaped hole 532 and the second U-shaped hole 534 of stacking connection setting, and first U-shaped hole 532 is located at lower lifting
On the outside of the end face of block 50, second U-shaped hole 534 is located on the inside of the end face of lower elevator 50, and the width of the first U-shaped hole 532
Less than second U-shaped hole 534, the side wall of first U-shaped hole 532 is embedded in the annular groove 122, the 2nd U
Shape hole 534 is matched with the thread segment 110.The linkage section 120 stretches out the lower elevator 50 by U-shaped through-hole 530, and under
