1. A removable hard disk structure without screws, comprising:
a housing comprising an opening end, a placing space and a door plate, wherein the placing space comprises a top surface and two side surfaces corresponding to each other, and the placing space is connected to the opening end so that the hard disk is placed into the placing space through the opening end;
at least one first elastic arm installed on the top surface and the first elastic arm comprising a first pressing end;
at least one second elastic arm installed on at least one side surface and the second elastic arm comprising a second pressing end; and
a removable component comprising a connecting end and a removable end, wherein the connecting end is installed on the housing;
when the hard disk is placed into the placing space through the opening end, the hard disk is tightly pressed by the first pressing end of the first elastic arm and the second pressing end of the second elastic arm, and the hard disk is thereby shifted within the placing space along a first linear direction; when the hard disk is placed into the placing space, the hard disk is shifted along a second linear direction by applying force on the removable end of the removable component.
2. The removable hard disk structure without screws as claimed in claim 1, wherein the first elastic arm is a cantilever structure, and the first pressing end keeps a first distance away from the top surface and extends into the placing space thereby.
3. The removable hard disk structure without screws as claimed in claim 1, wherein the second elastic arm is a cantilever structure, and the second pressing end keeps a second distance away from the top surface and extends into the placing space thereby.
4. The removable hard disk structure without screws as claimed in claim 1, wherein the top surface and the side surfaces are approximately perpendicular to each other.
5. The removable hard disk structure without screws as claimed in claim 1, wherein a connecting slot of the rear end of the hard disk is connected with a connecting head of the bottom end of the placing space through the hard disk tightly pressed by the first pressing end of the first elastic arm and the second pressing end of the second elastic arm.
6. The removable hard disk structure without screws as claimed in claim 1, wherein the first elastic arm is formed on the top surface of the placing space through integrated molding.
7. The removable hard disk structure without screws as claimed in claim 1, wherein the second elastic arm is formed on the side surfaces of the placing space through integrated molding.
8. The removable hard disk structure without screws as claimed in claim 1, wherein the removing component is attached to the hard disk as the hard disk is placed into the placing space.
9. The removable hard disk structure without screws as claimed in claim 1, wherein the removable component is made of a soft toughness material.
10. The removable hard disk structure without screws as claimed in claim 1, wherein the removable component is a tear strip.
11. The removable hard disk structure without screws as claimed in claim 1, wherein the removable component is a ribbon.
12. The removable hard disk structure without screws as claimed in claim 1, wherein the housing has a door plate corresponding to the opening end, and as the door plate is at the first position, the placing space is sealed, and as the door plate is at the second position the placing space is opened.
13. The removable hard disk structure without screws as claimed in claim 12, wherein the two sides of the opening end have two placing slots, and the door plate has hook holding bodies corresponding to the placing slots and is placed into the placing slots to fix the door plate to the opening end.
14. The removable hard disk structure without screws as claimed in claim 1, wherein the first linear direction is opposite to the second linear direction.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An endermic liniment comprising a polyoxyethylene dicarboxylate represented by the following chemical formula (1).
4
(In this formula, R1 and R2 are hydrogen or alkyl or branched alkyl groups having 1-4 carbon atoms, and m, n, X, and Y are integers 0-5 which are not all zero at the same time. R3 is a branched or linear chain alkylene group having 0-10 carbon atoms.)
2. The endermic liniment as defined in claim 1 wherein the polyoxyethylene dicarboxylate is diethoxy ethyl succinate.
3. The endermic liniment as defined in claim 1 or 2 which optionally contains a humectant.
4. An endermic liniment comprising a polyoxyethylene dicarboxylate which is represented by the following chemical formula (1), as well as one, two or more compounds selected from a group consisting of L-ascorbic acid or its derivative, a glucoside of hydroquinone or its derivative, and kojic acid or its derivative.
5
(In this formula, R1 and R2 are hydrogen or alkyl or branched alkyl groups having 1-4 carbon atoms, and m, n, X, and Y are integers 0-5 which are not all zero at the same time. R3 is a branched or linear chain alkylene group having 0-10 carbon atoms.)
5. The endermic liniment as defined in claim 4 wherein the polyoxyethylene dicarboxylate is diethoxy ethyl succinate.
6. The endermic liniment as defined in claim 4 or 5 which optionally contains a humectant.
7. The endermic liniment as defined in claim 4, 5, or 6 wherein said endermic liniment is a whitening endermic liniment.
