[0002] Denture equipment is a precision instrument and tool specially used for making dentures. It processes block or round materials to form tooth-like structures. Existing denture fixtures generally include a fixed slot block and a pressure cover. The material is placed in the fixed slot block and is squeezed and fixed on both sides by the pressure cover and bolts. However, when disassembling, it is generally necessary to remove all the bolts and pressure covers before the material can be taken out, resulting in cumbersome installation and disassembly steps. Alternatively, the material is taken out by pulling it out, which not only causes friction between the material and the fixed slot block, causing damage to the material, but also reduces replacement efficiency.

An L-shaped strip 2 is also provided on the fixing block 1, and a waist-shaped hole 21 is provided on the L-shaped strip 2. The waist-shaped hole 21 corresponds one-to-one to the first threaded hole, and the bottom of the L-shaped strip 2 is located at the top of the second step 13. A first bolt is provided in the waist-shaped hole 21, and the threaded section of the first bolt is threadedly matched with the first threaded hole to fix the fixing block 1 and the L-shaped strip 2, and the bottom of the L-shaped strip 2 abuts against the surface of the workpiece 6; at the same time, by loosening the first bolt, the L-shaped strip 2 can also slide on the surface of the fixing block 1 under the action of its waist-shaped hole 21, thereby moving the bottom of the L-shaped strip 2 to above the second step 13 to disengage from the fixation of the workpiece 6, which can improve the replacement efficiency of the workpiece 6.

[0039] When the workpiece 6 is processed and needs to be disassembled, the first bolt can be loosened to make the L-shaped beading 2 in a loose state, and then the L-shaped beading 2 can be moved on the surface of the fixing block 1, and the protruding bottom of the L-shaped beading 2 can be moved to the second step 13, and the workpiece 6 can be taken away directly. By setting a waist-shaped hole 21 and a second step 13 on the L-shaped beading 2, the first bolt can be slightly loosened to make the L-shaped beading 2 slide on the second step 13 to abut or disengage from the surface of the workpiece 6, thereby facilitating the installation and disassembly of the workpiece 6 without removing the L-shaped beading 2, thereby improving the replacement efficiency.

[0040] The fixing block 1 and the L-shaped strip 2 are basic components in the processing equipment.
