In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process can be called a fixture. However, the existing fixtures for metal workpiece processing have some shortcomings, such as:

[0003] Publication number: CN215201642U, a multi-stage clamp for processing metal products, by placing the metal product parts to be processed between the fixed clamp block and the movable clamp block, then reversely rotating the first bolt to start rotating and pushing between it and the first rotating ring, so that the movable clamp block slides in the slide groove and then the processed metal product is clamped between it and the fixed clamp block, and the contact of the first rubber pad prevents the outer surface of the metal product from being worn, thereby increasing the clamping range of the device and facilitating subsequent processing, thereby improving the practicality of the device. However, the device still has certain defects;

[0004] The operation process of the device requires manual rotation of the bolt, and the twisting force cannot guarantee that the workpiece will not loosen during the processing. The clamping direction is fixed, and the workpiece is prone to displacement during the processing. The operation is time-consuming and labor-intensive.

[0005] Therefore, we propose a multi-directionally adjustable metal workpiece processing fixture to solve the above-mentioned problems. Utility Model Content

[0008] Preferably, a slot is provided on the top of the column, and a clamping block is welded to the bottom end of the fixing block.

[0009] With the above structural design, the clamping block and the clamping slot can be clamped together, thereby facilitating quick separation of the fixing block and the column.

[0010] Preferably, the fixing block and the column form a clamping structure through a clamping block and a clamping slot, and limiting slots are provided on both sides of the clamping block.

[0011] With the above structural design, the limiting grooves are symmetrically arranged about the central axis of the clamping block, thereby facilitating the clamping connection between the limiting rod and the limiting groove.

[0012] Preferably, a cavity is opened inside the column, and the cavity is symmetrically arranged about the central axis of the column.

[0013] With the above structural design, the cavities are located on both sides of the column, and the limit rods slidably connected inside the cavity can move inside the cavity.

[0014] Preferably, a limiting rod is slidably connected inside the cavity, and the limiting rod is connected to the tension spring.

[0015] With the above structural design, when the limit rod is loose, the tension spring can drive the limit rod to reset.

[0016] Preferably, the tension spring is connected to the cavity, and the limiting rod and the cavity form an elastic structure through the tension spring.

[0017] With the above structural design, the limit rod can be driven to reset under the action of the tension spring, so that the limit rod has a limiting effect on the block.
