The matching mounting hole is vertically intersected and communicated with the locking pin mounting hole, and a conical shaft is arranged in the matching mounting hole. In the cross overlapping region of the fitting mounting hole and the locking pin mounting hole, the tapered revolving surface of the tapered shaft tenons the tapered revolving body at the fitting end from the fitting end radial direction, so that the tapered locking pin is locked in the axial direction. Thus, the locking pin and the shaft are locked by the tapered surface. The mating end is locked at least when in contact with the largest outer diameter surface of the conical surface of revolution on the tapered shaft and unlocked at least when in contact with the smallest outer diameter surface of the conical surface of revolution on the tapered shaft. The revolution surface of the matching end and the revolution surface of the conical shaft are both two revolution surfaces with gradually changed radial sizes, so that the whole technical effect can be achieved only by ensuring locking and unlocking matching at the limit position.
The end of the conical shaft further comprises a spring for providing a locking force, and the spring acts between the front end of the conical shaft and the bottom of the blind hole.
The conical shaft further comprises a step section surface which is inwards sunken in the radial direction, and a limiting pin matched with the step section surface is arranged on the bottom plate. Through the cooperation of spacer pin, the conical shaft can keep in the bottom plate, and the cooperation size of ladder section surface and spacer pin must be greater than the required activity size of conical shaft locking cooperation, just so can ensure normal locking and unblock.
An unlocking button used for pressing is installed on the outer end of the conical shaft, and a positioning pin and a positioning sleeve used for positioning the tool clamp are further arranged on the bottom plate.
The utility model has the advantages that: the utility model provides a pair of quick remodelling mechanism without instrument has higher stability, and joint strength, and locking ability is strong, and easy operation is convenient, and the repeatability of structure is high moreover, is suitable for middle-size and small-size frock rapid prototyping.
