Embodiment

As shown in Figures 1 to 4, basically, jacking gear of the present utility model is by a pedestal 1, and a pair of fixed rack 2, is stirred key 3, a pair of movable slide rail 4, and a connecting rod 5 combines.

Pedestal 1 is a pedestal, its both sides are projection one ㄇ shape sidewall 11 separately, enclose and form a room 12, in order to after chat the ccontaining of connecting rod 5 and use with the location, a pair of known fixed rack 2 then is connected in this oppose side wall 11, for example pass through at least one hole that each sidewall 11 is preset, and be screwed together in a fixed rack 2, this is towered in these pedestal 1 both sides opposite to each other to fixed rack 2 with screw.

11 of the two sides in this pedestal 1 the place ahead form the keyways 13 of a horizontal strip, for after chat to stir key 3 sheathed in it, these keyway 13 end faces communicate with room 12, and a side opens a keyhole 14, for an elastic parts 15, for example spring ccontaining with locate usefulness.

Stirring key 3 is a strip block, it is inserted in the aforesaid keyway 13, and corresponding to the sidewall of these keyhole 14 positions projection one key tenon 31 then, it wears this elastic parts that is positioned at keyhole 14 15, by the stretching, extension elastic force of this elastic parts, make this stir the opposite side that key 3 is resisted against keyway 13 constantly.See also Fig. 2, can form the state of automatically locking for making this connecting rod 5 touch this shifting part 3 when moving down, these shifting part 3 inner face apical margins are formed down to a few groove 32, projection one inclined-plane tenon 33 in the one side direction.Further, for convenient operation, so its place ahead is provided with a clicking section 34 to this shifting part 3, as shown be a prominent tenon, only not as limit, it also must be shrinkage pool or equivalent, make this stir key 3 can be in keyway 13 transversal displacement, and compress this elastic parts 15, to remove locking state.

This is a known technology to movable slide rail 4, its be provided with in opposite directions and be socketed on aforementioned this between the fixed rack 2, it risen or move down, only this is a known technology all, does not intend giving unnecessary details at this.And be to form the clip effect of locking, this connects a horizontal connecting rod 5 to movable slide rail 4 bottoms.See also Fig. 1 and Fig. 3, corresponding each inclined-plane tenon 23 position projections one trip 51 of these connecting rod 5 the place ahead root edges, its end face circular arc is good, the friction force that it can be less is moved down along inclined-plane tenon 33, making this stir key 3 moves and with its compression, when this trip 51 fell in the groove 32, this elastic parts 15 stretched at once towards elastic parts 15, make each trip 51 be 33 buckles of inclined-plane tenon, promptly form locking state as shown in Figure 4.

As shown in Figure 3, these connecting rod 5 bottom surfaces have an arc concave surface 52, and in conjunction with usefulness, it is not an emphasis of the present utility model, so do not intend giving unnecessary details for known fixed force spring for it.

Remove locking state as desire, only need stir the clicking section 34 in key 3 the place aheads, for example prominent tenon, make its elasticity of compression assembly 15, make these inclined-plane tenons 33 when being displaced sideways, itself and each trip 51 are broken away from and form released state, make this connecting rod 5 can be, and then break away from groove 32 with this to moving on the movable slide rail 4.At this moment, decontrol clicking section 34, this stirs key 3 again by the stretching, extension of elastic parts 15, and the involution original position.

The utility model is described, and just preferred embodiment is a kind of, such as Ju Bu change or modification and come from technological thought of the present utility model and be have the knack of this technology personnel were easy to know by inference, all do not take off claim category of the present utility model.
