It is set as 0.5cm.
Preferably, the length of the thread cavity is greater than the length of the threaded portion of screw, and the length of annular groove is big
In the length of screw thread chamber；And the thread cavity is identical as the length of accommodating chamber.
The utility model has the advantages that the invention has the following advantages:
(1) the connection sleeve of lower case is set as thread cavity and accommodating chamber two parts in the present invention, and the top of accommodating chamber
Lateral block is also installed by torsionspring, threaded portion and the rear end annular groove of front end are also accordingly set on screw, installation
When, screw is passed through from via hole, is pressed down against lateral block, downwardly turn over lateral block, and when threaded portion screw in downwards to
In thread cavity, the position of annular groove is corresponding with lateral block on screw, after lateral block loses the limitation in nose threads portion,
It is replied under the action of torsionspring as transversely and horizontally state and is accordingly extend into annular groove；It is twisted in thread cavity threaded portion
Tightly, lateral block is accordingly placed in annular groove, and upper and lower casing is fixed, the fixation of upper-lower casing is achieved；
(2) when needing to split upper-lower casing, it is only necessary to screw is turned, the threaded portion of screw is screwed out from thread cavity,
Just realize the separation of upper-lower casing, and at this point, after the threaded portion of screw screws out, but lateral block is still the ring for being stuck in screw
In connected in star, allowing for screw in this way is that entirety is seized, although the distance between adjustment upper-lower casing can be moved up and down,
It is that entirety is stuck between lateral block, neither interferes upper-lower casing maintenance dismantling in this way, and can guarantee that screw is not lost；
And when needing to take out screw, it is only necessary to it firmly pulls outward, because lateral block is installed by torsionspring,
When extruding inwardly can inside side to overturn realize and install, and pull, can flip to the outside, lateral block card is not outward
It firmly just pulls out, disassembles from the via hole of upper housing after annular groove；The present apparatus can make transverse direction from the natural installation of screw
Fixture block is stuck in annular groove, convenient to use when installation, does not have to nuisance operation；And in cross when dismantling upper-lower casing
It realizes that screw is anti-lost, pulls, and screw can be removed from shell finally by external force under the action of to fixture block, realizes three
The function of a aspect, it is very convenient.
Detailed description of the invention
Fig. 1 is structure of the invention figure；
Fig. 2 is enlarged drawing at A in Fig. 1.
Specific embodiment

Premised under implemented, it should be understood that these examples are only for illustrating the present invention and are not intended to limit the scope of the present invention.
As depicted in figs. 1 and 2, a kind of anti-lost screw attaching/detaching apparatus, including upper housing 1 and lower case 2；The upper casing
It is provided with via hole 3 on body 1, and is then provided with connection sleeve 4 corresponding with 3 position of via hole in the lower case 2, this is described
Connection sleeve 4 includes the accommodating chamber 6 positioned at the thread cavity 5 of downside and positioned at upside；The outer diameter of the accommodating chamber 6 is greater than
The outer diameter of thread cavity 5；One screw 7 is installed in the via hole 3；The middle and lower part outer diameter of the screw 7 and thread cavity 5
Intracavitary diameter matches, and is provided with corresponding threaded portion 8；And the middle and upper part of screw 7 is then provided with the annular being recessed inwardly
Groove 9；And the top two sides of the accommodating chamber 6 are also equipped with prolonging inwardly of being laterally arranged by a torsionspring 10 respectively
The lateral block 11 stretched, two torsion bars of torsionspring 10 are separately mounted on the inside of the upper end of accommodating chamber 6 and lateral block 11
Lower end side, the home position of lateral block 11 is transversely and horizontally to stretch out under the action of torsionspring 10, and the transverse gear
11 extension elongation of block is arranged to extend into annular groove 9；The screw 7 is inserted into connection sleeve 4 from via hole 3,
8 outer diameter of threaded portion of front end is greater than the distance between two sides transverse direction block 11, is pressed down against lateral block 11, makes lateral block 11
It downwardly turns over, and when threaded portion 8 is screwed in into thread cavity 5 downwards, the position of the annular groove 9 of screw 7 and lateral block 11 are right
It answers, after lateral block 11 loses the limitation in nose threads portion 8, is replied under the action of torsionspring 10 as transversely and horizontally state simultaneously
Accordingly it extend into annular groove 9；Threaded portion 8 is tightened in thread cavity 5, and lateral block 11 is accordingly placed on annular groove 9
In, upper and lower casing is fixed.
The end of the screw 7 is provided with nut 12；And cross recess 13 is provided on the nut 12；The upper casing
