To achieve these goals, the utility model has adopted following technical scheme:
A kind of elastic telescopic supporting leg, it is characterized in that it is made up of a fixing outer sleeve and an inner sleeve that matches with outer sleeve, in, be provided with back-moving spring between outer sleeve, the outer sleeve inwall is provided with a locating slot, locating slot is joined by segment length's groove and a peach shape groove and forms, be provided with two fixed points down in the peach shape groove, be provided with a raised points between twice fixed points, peach shape groove middle part is provided with a L shaped location block piece, block piece L shaped goes up flex point and is located at going up of elongated slot end points and fixes a point relative and be offset certain distance, two end points of block piece are fixed a point relative down with two respectively and are offset certain distance, it is relative and be offset certain distance that the raised points of peach shape groove bottom and block piece L shaped goes up flex point, the inner sleeve face of cylinder is provided with guidepost and moves in locating slot, and with locating slot on, following fixed point and L shaped block piece form the location and cooperate.The acting force of back-moving spring makes guidepost have the movement tendency of fixing a point in the sensing all the time.
Based on such scheme, also can on the inner sleeve face of cylinder, be provided with a locating slot, locating slot is joined by segment length's groove and a peach shape groove and forms, be provided with two fixed points down in the peach shape groove, be provided with a raised points between twice fixed points, peach shape groove middle part is provided with a L shaped location block piece, block piece L shaped goes up flex point and is located at going up of elongated slot end points and fixes a point relative and be offset certain distance, two end points of block piece are fixed a point relative down with two respectively and are offset certain distance, it is relative and be offset certain distance that the raised points of peach shape groove bottom and block piece L shaped goes up flex point, the outer sleeve inwall is provided with guidepost and moves in locating slot, and with locating slot on, following fixed point and L shaped block piece form the location and cooperate.The acting force of back-moving spring makes guidepost have the movement tendency of fixing a point in the sensing all the time.
Owing to adopted technical scheme described in the utility model, the elastic telescopic supporting leg is outer sleeve, inner sleeve and three parts of spring only, as long as one press gently, just the elastic telescopic supporting leg can be stretched out or regains, make to the utlity model has advantage simple and compact for structure, easy to manufacture, with low cost, that volume is little, stroke is big, easy to use, it can be widely used in the equipment such as notebook computer, computor-keyboard.
For the utility model is described in further detail, following accompanying drawing provides a most preferred embodiment of the present utility model.

Fig. 3 is the cut-open view (locating slot is arranged in the outer sleeve) of the utility model extended configuration;
Fig. 4 is that the utility model locating slot is arranged on the cut-open view in the inner sleeve;
Fig. 5 is the A-A cut-open view of Fig. 4;
Fig. 6 is that the utility model is used for the synoptic diagram that notebook computer is in contraction state;
Fig. 7 is that the utility model is used for the synoptic diagram that notebook computer is in extended configuration;
Embodiment:
Embodiment: as shown in Figure 1, locating slot B is made up of elongated slot 3 and peach shape groove 4, the bottom of peach shape groove 4 is respectively equipped with down fixed point 6,8, be provided with raised points 7 upwards between them, be provided with opening above the peach shape groove 4 and link to each other with elongated slot 3, be provided with a L shaped block piece 5 at the middle part of peach shape groove 4, its last flex point 5a and elongated slot 3 ends go up the fixed point 1 relative certain distance that also is offset left; The right endpoint 5b of L shaped block piece 5 and the 6 relative certain distances that also are offset to the right of fixing a point down; The left end point 5c of L shaped block piece 5 and the 8 relative certain distances that also are offset to the right of fixing a point down; Raised points 7 and the inboard relative certain distance that also is offset to the right of last flex point 5a.
Its course of work is as follows: the guidepost 2 that is arranged in locating slot B is run into behind the right side of last flex point 5a of L shaped block piece 5 lower slider to the right to lower slider under the effect of external force, falls into down fixed point 6 places, stop motion after crossing right endpoint 5b; Remove external force this moment, and under the effect of spring, guidepost 2 moves upward, and the inboard inboard and the supreme flex point 5a that moves upward of running into L shaped block piece 5 is in steady state (SS); Apply external force this moment again, guidepost 2 moves downward the left side of running into raised points 7 and slides into down fixed point 8 places stop motion; Remove external force this moment, and under the effect of spring, guidepost 2 moves upward along the left side of peach shape groove 4 and enters elongated slot 3, and 1 place finishes a motion process until last fixed point.
Elastic telescopic supporting leg described in the utility model as Fig. 2, shown in Figure 3, is made up of outer sleeve 9 and sheathed inner sleeve 11, is provided with spring 10 in the inner sleeve 11, and its end links to each other with the bottom of inner sleeve 11, and the other end links to each other with the upper end of outer sleeve 9.On the inwall of outer sleeve 9, be provided with locating slot B, its structure as shown in Figure 1, the face of cylinder of inner sleeve 11 is provided with guidepost 2, it match with locating slot B the location situation as shown in Figure 1, mistake described above.Fig. 2 is that the guidepost 2 in the inner sleeve 11 is positioned at L shaped block piece inboard, is in contraction state, when to pressing down outer sleeve 9, and then when unclamping, under the effect of spring, guidepost 2 will move to the elongated slot lower end along peach shape groove and elongated slot, is in extended configuration as shown in Figure 3.Press outer sleeve 9 once more down, guidepost 2 moves to the inboard location of L shaped block piece the peach shape groove from the elongated slot lower end, be in contraction state again.Can certainly adopt as Fig. 4, structure shown in Figure 5, be about to locating slot B and be arranged on the face of cylinder of inner sleeve 11, guidepost 2 is arranged on the inner cylinder face of outer sleeve 9, also can reach same purpose.
The elastic telescopic supporting leg is applied to situation such as Fig. 6, shown in Figure 7 of notebook computer, Fig. 6 is in contraction state for the elastic telescopic supporting leg, downwards by following notebook computer 12, under the effect of spring, inner sleeve 11 stretches, 12 of notebook computers are in heeling condition, so that the user operates.
