The inner end side wall screw for determining block 1 is fixed with rubber ring 5, and rubber ring 5 is equipped with lead screw 4, and the inner end of first set block 2 passes through elasticity dress
It sets 12 and is connected with elastic webbing 13, elastic device 12 includes to place block 121, elastic rod 122, support rod 123 and spring 124, the
A set of piece 2 of inner end side wall screw, which is fixed with, places block 121, and the top for placing block 121 slidably connects elastic rod 122, and first
The bottom end screw of set block 2 is fixed with rotating bar 11, and the other end key connection of rotating bar 11 has sliding axle 10, and the sliding of sliding axle 10 connects
It is connected to second set of block 3；
The inner end of threaded hole 7 is equipped with internal screw thread, and the outer end of screw rod 8 is equipped with external screw thread, and screw thread connects between threaded hole 7 and screw rod 8
It connects, and fixed block 1 is fixedly connected by threaded hole 7 by screw rod 8 with sliding shoe 6, the outer end fixation of lead screw 4 is set in elastic webbing
13 inside, the internal slide of rubber ring 5 are arranged with lead screw 4, the flexible band 13 of the other end glue connection of elastic rod 122, elasticity
The bottom end glue connection of bar 122 is connected to spring 124, and the other end glue connection of spring 124 and is supported in the bottom end inner wall of support rod 123
Bar 123 is located at the inner wall for placing block 121, and the inside of second set of block 3 offers sliding groove 9, and the internal slide of sliding groove 9 is connected with
Sliding axle 10, the flexible bar 122 of the bottom end side wall glue connection of second set of block 3, the flexible band of other end glue connection of elastic rod 122
13, the internal slide of elastic webbing 13 is arranged with lead screw 4；
The present invention, by sliding sliding shoe 6 on fixed block 4, so that the inside of rubber ring 5 will be allowed to place difference
The lead screw 4 of diameter expands making for lead screw 4 so that the use scope that lead screw 4 fixes device during connecting and applying is extensive
With range, reduce the limitation of lead screw 4 during the connection process, by using first set block 2 and second set of block 3 fixed wire again
Thick stick 4 plays the role of triple fixations to lead screw 4, so that lead screw 4 is even so that lead screw 4 is fixed more preferable during use
That fixes when connecing is more complete.
Embodiment one: the present apparatus is when being fixed lead screw, due to passing through connection between fixed block 1 and second set of block 3
What bar was fixed together, it needs for lead screw 4 to be fixed on the inside of fixed block 1, first set block 2 and second set of block 3, fixes
Process is: lead screw 4 being inserted through to the inside of fixed block 1, first set block 2 and second set of block 3, according to the diameter of screw rod 4 by sliding shoe 6
It is slided on fixed block 1, so that sliding shoe 6 and the area of the intermediate enclosure of fixed block 1 become larger, since rubber ring 5 has elasticity
And it is smooth structure that rubber ring 5, which is close to the one side of lead screw 4, to rubber ring 5 can also be widened, and then lead screw 4 is placed on
The inside of rubber ring 5 then slides sliding shoe 6 on fixed block 1, so that rubber ring 5 is entangled lead screw 4, and lead screw 4
It can also be slided in rubber ring 5, the inside of threaded hole 7 is then injected using screw rod 8, so that screw rod 8 will be slided by threaded hole 8
Motion block 6 is fixed up with fixed block 1, and lead screw 4 is when injecting the inside of first set block 2 and second set of block 3, in insertion lead screw 4
In the process, since the inside of first set block 2 and second set of block 3 is designed with elastic webbing 13, elastic webbing 13 has elasticity, therefore elasticity
Band 13 can stretch, when the lead screw 4 of different-diameter is inserted into the inside of first set block 2 and second set of block 3, the big lead screw of diameter
4 can be taut big by elastic webbing 13, and the elastic rod 122 on first set block 2 can in the internal slide for placing block 121, and
Spring 124 also can play the role of resilient support to elastic rod 122, so that the lead screw 4 in major diameter is inserted into first set
When in block 2, elastic device 12 can also have elastic force, so that lead screw 4 can preferably be inserted into the elasticity in first set block 2
In band 13, when in the fixed first set block 2 of lead screw 4, first set block 2 and lead screw 4 are fixed up using screw；
Embodiment two: when lead screw 4 is fixed on the inside of fixed block 1, first set block 2 and second set of block 3, if lead screw 4 is turning
When dynamic, lead screw 4 can be rotated together with first set block 2, and lead screw 4 can turn in the inside of fixed block 1 and second set of block 3
Dynamic, when lead screw 4 is rotated with first set block 2, the rotating bar 11 on first set block 2 can be with sliding axle 10 in second set of block 3
On sliding groove 9 in sliding so that second set of block 3 plays the role of support to screw rod 4.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
