the utility model provides a change auto-lock instrument of accessory, includes fixed frame, accessory group, sleeve, to locking screw and O type gasket, the screw is seted up to fixed frame one end, the sleeve is fixed in fixed frame's screw through locking screw locking, and accessory group is including a plurality of parallel arrangement's accessory, and the shaft hole is seted up to accessory one end, the sleeve passes the shaft hole of accessory and realizes normal running fit, makes the accessory change over to or roll over to fixed frame around the sleeve, is equipped with 1 at least O type gasket between two adjacent accessories.

Further, the accessory group comprises a key blank, a scissor group and an express delivery knife, wherein the key blank, the scissor group and the express delivery knife are sequentially arranged in parallel from top to bottom.

Further, the sleeve is a copper sleeve.

Further, the locking screw is composed of a male screw and a female nut, the fixing frame comprises an upper plate and a lower plate, corresponding screw holes are formed in one ends of the upper plate and the lower plate, inner grooves are formed in the peripheries of the screw holes, the male screw and the female nut enter the sleeve from the screw holes of the upper plate and the screw holes of the lower plate respectively, and the nut of the male screw and the nut of the female nut lock the inner grooves of the upper plate and the lower plate respectively.

After the scheme is adopted, the utility model discloses an align with the screw of shaft hole, O type gasket and the fixed frame of accessory earlier during auto-lock instrument installation, penetrate shaft hole, O type gasket and screw with the sleeve simultaneously again, fix the sleeve locking on fixed frame through locking the screw at last, open when needing to change the accessory to locking the screw, take off the sleeve can.

Compared with the prior art, the utility model has the following advantage: not only the dismouting is simple, convenient to use, and the cost is lower, has improved the interest of using moreover, can change the accessory according to the demand at any time, satisfies masses of users' user demand, and O type gasket can not only increase the frictional force between the accessory, avoids the accessory to roll out at will, can also reduce wear.
