Of the present utility modelly further be set to: described the shank of the key is made of two housings that fasten mutually, the joining place of two housings outer side edges is provided with the cavity volume of placing key on the shank of the key, the other end that key is provided with key tooth one end relatively is connected with spill spin block, this spill spin block and the shank of the key are articulated and connected by jointed shaft, be arranged with on the jointed shaft for its back-moving spring that resets, one end of jointed shaft penetrates outside housing on the shank of the key is revealed in, and jointed shaft is provided with fixture block, and the correspondence position of fixture block is provided with draw-in groove on the shank of the key upper shell and the jointed shaft.
Adopt technique scheme; can be by pushing jointed shaft; make on the jointed shaft that the spacing cooperation between draw-in groove contacts on the fixture block and the shank of the key; can pass through screw key then; key is rotated around jointed shaft, and key is received to cavity volume the most at last, realizes the folding of key; key has been played protective effect, avoided the key tooth owing to the unexpected situation that fractures.
Of the present utility modelly further be set to: described spill spin block is provided with axis hole, jointed shaft is installed in axis hole, the axis hole inboard be installed on jointed shaft on the suitable stopper slot of fixture block, fixture block is arranged in the circumferential spacing cooperation that constitutes jointed shaft and spill spin block in the stopper slot, correspondence position with the spill spin block upper shaft hole on the described the shank of the key is provided with limited block, one end and the limited block of back-moving spring are fixed, and the other end and jointed shaft are fixed.
Adopt technique scheme, jointed shaft constitutes spacing the cooperation with the shank of the key and spill spin block respectively, and have only as the jointed shaft Shi Caihui that is pressed and remove spacing the cooperation with the shank of the key, realize the selection of key, again because the setting of back-moving spring, after making that jointed shaft is pressed, perhaps all has the active force that key is ejected after the spill spin block rotation, thereby made things convenient for user's use, in addition back-moving spring not only have the compression reset, also have the effect of reverse reset, thereby realized the effect that the multiple function of a spring is wholely set, simplify the structure.
Of the present utility modelly further be set to: described spill spin block is provided with key and is provided with the relative adaptive holddown groove of the other end of key tooth one end again, the side that key is provided with the relative other end of key tooth one end is provided with runs through the axial key draw-in groove of key, the key draw-in groove is positioned at holddown groove, position relative with the key draw-in groove on the spill spin block is provided with fixing hole, is installed on elastic cylindrical pin in the gap that key draw-in groove and fixing hole are constituted.
Adopt technique scheme,,, can change, maintain easily key by taking out elastic cylindrical pin as the situation that key is fractureed truly having occurred.
Below in conjunction with accompanying drawing the utility model is further described:
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the explosive view of the utility model embodiment.
Fig. 3 is the explosive view of the utility model embodiment.
Fig. 4 is the schematic diagram of the utility model embodiment spill spin block, back-moving spring and jointed shaft.
The specific embodiment
Shown in Fig. 1,2,3,4, present embodiment includes key 1 and the shank of the key 2, and the centre of described key 1 is provided with a groove 11, and the inboard on the both sides of groove 11 is provided with profile of tooth tooth inequality, constitutes the key tooth thus.The shank of the key 2 is made of two housings 21 that fasten mutually, the joining place of two housings 21 outer side edges is provided with the cavity volume 22 of placing key on the shank of the key 2, the other end that key 1 is provided with key tooth one end relatively is connected with spill spin block 3, this spill spin block 3 is articulated and connected by jointed shaft 4 with the shank of the key 2, be arranged with on the jointed shaft 4 for its back-moving spring that resets 5, one end of jointed shaft 4 penetrates outside housing 21 on the shank of the key 2 is revealed in, and jointed shaft 4 is provided with fixture block 41, and the correspondence position of fixture block 41 is provided with draw-in groove 221 on the shank of the key 2 upper shells 21 and the jointed shaft 4.Wherein, spill spin block 3 is provided with axis hole 31, jointed shaft 4 is installed in axis hole 31, axis hole 31 inboards be installed on jointed shaft 4 on the suitable stopper slot 32 of fixture block 41, fixture block 41 is arranged in the circumferential spacing cooperation that constitutes jointed shaft 4 and spill spin block 3 in the stopper slot 32, correspondence position with spill spin block 3 upper shaft holes 31 on the described the shank of the key 2 is provided with limited block 212, and an end of back-moving spring 5 and limited block 212 are fixing, and the other end and jointed shaft 4 are fixing.In addition, spill spin block 3 is provided with key 1 and is provided with the adaptive holddown groove 33 of the relative other end of key tooth one end, the side that key 1 is provided with the relative other end of key tooth one end is provided with runs through the axial key draw-in groove 12 of key 1, key draw-in groove 12 is positioned at holddown groove 33, position relative with key draw-in groove 12 on the spill spin block 3 is provided with and the suitable fixing hole 34 of key draw-in groove 12 length, is installed on elastic cylindrical pin 35 in the gap that key draw-in groove 12 and fixing hole 34 are constituted.
