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, 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.
Of the present utility modelly further be set to: the centre of described key is provided with a groove, and the inboard on the both sides of groove is provided with profile of tooth tooth inequality again.
Adopt technique scheme, the key of interior toothing, mutual opening rate is far below outer teeth key, be not easy to be copied, safe in utilization, and interior toothing makes the production of key to thicken, whole rigidity and intensity strengthen, avoided distortion, the bending of key or fractureed, also novel and beautiful of moulding in addition, comfortable feel.
Below in conjunction with accompanying drawing the utility model is further described:
