The specific embodiment

The utility model exemplary embodiments is to be made of a drawer 1, support 2, desktop 3, a right double-deck bracket 4 and the double-deck bracket 5 in a left side, shown in Fig. 1～4, wherein:

Drawer 1 is to be in desktop 3 belows that support 2 is supported, and facing to the staff of sitting posture, and again, this drawer 1 is in (not shown) on the longitudinal rail that desktop 3 is provided with below, can do forward and backward push-and-pull along the staff towards sitting posture; The front of drawer 1 has a drawer panel 11, more than all belong to prior art;

Right double-deck bracket 4 mainly is to go up groove seat 44 and four connecting rods 45 constitute by the following groove seat of the upper right plate of a bottom right plate 41, a block 42, four 43, four, shown in Fig. 1,2,5 and 6, wherein:

The right edge of bottom right plate 41 is vertical side, the front is that a short trough rim and back are a long horizontal edge, and the limit, left side is formed by concavity circular arc limit, and this bottom right plate 41 is used hinge (ready-made hinge on this long horizontal edge, or dull and stereotyped hinge or bending hinge) be connected on the inboard, drawer panel 11 right top of drawer 1, these bottom right plate 41 upper surfaces are respectively equipped with four parallel grooves separately for four jiaos;

The profile of upper right plate 42 and bottom right plate 41 shapes are roughly the same, but generally the former is longer than the latter.These upper right plate 42 lower surfaces are respectively equipped with four parallel grooves separately for four jiaos, and corresponding with the groove of bottom right plate 41;

Following groove seat 43 is to extend the left and right wide flat board of sustained height on a left and right top of concave-board and form, and relative a pair of through hole 431 is set in the middle of the concave-board left and right side, in addition, in the middle of base plate, also be provided with keeper, as: the rectangular opening that matches with connecting rod 45 lower ends is set in the middle of the base plate, or alignment pin, location link stopper etc. are set, as shown in Figure 7, this time groove seat 43 places in the groove of bottom right plate 41, and fixedlys connected with bottom right plate 41 with screw at left and right wide dull and stereotyped place;

Last groove seat 44 is to extend the left and right wide flat board of sustained height a left and right bottom of concave-board and form, and relative a pair of through hole 431 is set in the middle of the concave-board left and right side, last groove seat 44 is actual to be that groove seat 43 turns over the structure of turnback down, with reference to Fig. 7, should go up groove seat 44 and place in the groove of upper right plate 42, and fixedly connected with upper right plate 42 with screw at left and right wide dull and stereotyped place;

To be flat laths be provided with a long slot bore 451 respectively and form near upper and lower end connecting rod 45, as shown in Figure 8, pass a pair of through hole 431 of lower end long slot bore 451 and following groove seat 43 respectively with a bearing pin, pass a pair of through hole 441 of upper end long slot bore 451 and last groove seat 44 equally with another bearing pin, so, this connecting rod 45 is articulated in down between groove seat 43 and the last groove seat 44, can make 45 swings of this connecting rod and forms connecting rod 45 and be skewed and erect shape, shown in Fig. 5,6;

Equally, double-deck the bracket 5 in a left side mainly is to go up groove seat 44 and four connecting rods 45 constitute by the following groove seat of the upper left plate of a lower-left plate 51, a block 52, four 43, four, shown in Fig. 1,2,5 and 6, wherein:

The limit, left side of lower-left plate 51 is vertical side, the front is that a hyphen limit and back are a long horizontal edge, and right edge is formed by concavity circular arc limit, and this lower-left plate 51 is used hinge (ready-made hinge on this long horizontal edge, or dull and stereotyped hinge or bending hinge) be connected on the inboard, drawer panel 11 left top of drawer 1, these lower-left plate 51 upper surfaces are respectively equipped with four parallel grooves separately for four jiaos; But the plate face of double-deck the bracket 5 in a left side is than a right double-deck bracket 4 littler (because common people use the right-hand operated mouse, need prop up on the bracket 4 removable position more greatly at right bilayer), shown in Fig. 3,4;

The profile of upper left plate 52 and lower-left plate 51 shapes are roughly the same, and generally the former is more longer than the latter;

The structure of upper left plate 52, lower-left plate 51 structure with upper right plate 42, bottom right plate 41 respectively is identical, so do not give unnecessary details;

Identical as for four following groove seats 43, four interconnected relationships that go up groove seat 44 and four connecting rods 45 with right double-deck connection of propping up in the bracket 4, so do not give unnecessary details.

Operation of the present utility model and operation principle:

When upper right plate 42 of pulling and upper left plate 52, make connecting rod 45 be in heeling condition, at this moment, upper right plate 42 directly contacts and is supported on the bottom right plate 41, upper left plate 52 contacts also are supported on the lower-left plate 52, and upper right plate 42 is in identical lower position with upper left plate 52, as shown in Figure 5:

When promoting upper right plate 42 and upper left plate 52, make connecting rod 45 be in stable upright state, at this moment, upper right plate 42 is supported in (upper right plate 42 and bottom right plate 41 are thrown off) on the bottom right plate 41 by connecting rod 45, upper left plate 52 is supported in (upper left plate 52 and lower-left plate 51 are thrown off) on the lower-left plate 51, upper right plate 42 is in identical high position with upper left plate 52, as shown in Figure 6;

Result of use of the present utility model:

If the lower position of above-mentioned upper right plate 42 and upper left plate 52 be set to desktop 3 upper surfaces sustained height (or high slightly), be applicable to general desk, for reading or write; If the high position of above-mentioned upper right plate 42 and upper left plate 52 is set to be higher than desktop 3 height, and with the keyboard of notebook computer of placing on the desktop 3 or desktop computer keyboard upper surface sustained height (or high slightly), be applicable to the notebook computer on the operation desktop 3 or the computer desk of desktop computer;

If the lower position of above-mentioned upper right plate 42 and upper left plate 52 is set to be lower than desktop 3 lower surfaces (back side) with drawer in the desktop computer keyboard upper surface placed sustained height (or high slightly), be applicable to the computer desk of operating desktop computer; If the high position of above-mentioned upper right plate 42 and upper left plate 52 is set to upper surface with desktop 3 sustained height (or high slightly), be applicable to general desk, for reading or write.
