Abstract

The utility model relates to a telescopic key which comprises an upper shell, a lower shell and a key plate, wherein the key plate is arranged in a slide way of the lower shell to make the key plate extend out of the lower shell and retract into the lower shell. A back positioning groove and a front positioning groove are arranged on the side of the lower shell. A connecting block is arranged at the back end of the key plate, a telescopic hole is arranged on the connecting block, and a control rod and a spring are arranged in the telescopic hole. A positioning flange is arranged on the control rod. When the key plate extends out of the lower shell, the positioning flange is inlaid into the back positioning groove. When the key plate retracts into the lower shell, the positioning flange is inlaid into the front positioning groove. Thus, the key plate can be positioned firmly when the key plate extends out of the lower shell or retracts into the lower shell.

Description

Telescopic key

Technical field

The utility model relates to a kind of telescopic key.

Background technology

In the prior art, outside the extended housing of the key piece of telescopic key, in the income housing, has half deep-slotted chip breaker in its housing, has the semi arch salient point on the key piece, by semi arch salient point and the mutual clip of half deep-slotted chip breaker, make key piece location, but since the clip power between half deep-slotted chip breaker and the semi arch salient point a little less than, the location mistake that easily causes key piece causes and uses inconvenience.

Summary of the invention

The utility model purpose provides a kind of telescopic key, and the location of its key piece is firm.

For achieving the above object, the technical solution adopted in the utility model is: a kind of telescopic key, comprise upper shell, lower house, key piece, described key piece is arranged in the chute of lower house slidably, described key piece has two operating positions at least, and under first operating position, described key piece stretches out outside the lower house, under second operating position, in the described key piece income lower house.

The side portion of described lower house has back locating slot and prelocalization groove, and a side of described lower house is provided with the breach that is connected with described chute;

The rearward end of described key piece has contiguous block, have telescopic hole on the described contiguous block, be provided with control lever and spring in the described telescopic hole, one end of described control lever exposes outside the lower house from the breach of lower house, has locating flange on the described control lever, when described key piece is in first operating position, the locating flange of described control lever embeds in the locating slot of back, when described key piece was in second operating position, the locating flange of described control lever embedded in the prelocalization groove.

Because technique scheme utilization, the utility model compared with prior art has following advantage: by cooperating of the locating flange and the prelocalization groove of control lever, back locating slot, make that key piece stretches out outside the lower house, the firm position when the income lower house is interior, thereby make the flexible easy to operate, quick of key piece, and can avoid touching and making the stretching out or take in mistake of key piece owing to mistake.
