Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The staff needs to use the clamp 3 to clamp and fix the workpiece to the left and right, by opening the support block 9, and driving the gear 1 11 to rotate through the support block 9, and through the meshing between the gear 11 and the gear 2 12, the gear 1 11 drives the gear 2 12 to rotate, and the gear 2 12 drives the two-way screw 19 to rotate inside the workbench 1 and the threaded sleeve 2, and then drives the fixed round block 20 to rotate through the two-way screw 19, so that the threaded sleeve 2 slides inside the slide groove 8, and drives the two to the inside of the clamp 3, and the workpiece is clamped and fixed to the left and right through the cooperation of the two clamps 3, thereby completing the left and right clamping and fixing of the workpiece.
[0024] The workpiece needs to be clamped and fixed by the fixture 3 to the left and right, by opening the support block 9, the support block 9 drives the gear 1 11 to rotate, the gear 1 11 drives the gear 2 12 to rotate, the gear 2 12 drives the bidirectional screw 19 to rotate inside the workbench 1 and the threaded sleeve 2, and the bidirectional screw 19 drives the fixed round block 20 to rotate, so that the threaded sleeve 2 slides inside the slide groove 8, and drives the two to the inside of the fixture 3. The workpiece is clamped and fixed by the cooperation of the two fixtures 3. Compared with the traditional fixture, the gear 1 11, the gear 2 12 and the bidirectional screw 19 are used to rotate the workpiece. The cooperation between the screw rod 19 makes it easy to drive the threaded sleeve 2 and the clamp 3 to move inward to clamp the workpiece on the left and right sides. This ensures that the workpiece remains stable during processing, effectively avoids movement and deformation caused by external force or vibration, and greatly improves processing accuracy and product quality. This clamping method can evenly distribute the clamping force, reduce stress concentration and deformation, and maintain the stability of the shape and size of the workpiece.

[0025] Among them, a clamping plate 6 is movably installed inside the clamp 3, a pull rod 5 is fixedly installed on the top of the clamping plate 6, and one end of the pull rod 5 completely passes through the inside of the clamp 3, a fixing block 4 is fixedly installed on the top of the pull rod 5, and a spring 7 is fixedly installed between the top of the clamping plate 6 and the top of the inside of the clamp 3.
[0026] After the staff has completed the left and right clamping of the workpiece, it is necessary to clamp and fix the workpiece up and down, through the fixing block 4, pull the pull rod 5 inside the clamp 3 through the fixing block 4, and then drive the clamping plate 6 to pull through the pull rod 5, and then squeeze the inside of the clamp 3 through the clamping plate 6, and then put the workpiece into the inside of the clamp 3. Now, let go of the fixing block 4. At this time, the clamping plate 6 squeezes the clamping plate 6 inside the clamp 3 through the spring 7 and the pull rod 5, and the cooperation between the clamping plate 6 and the sponge pad 18 facilitates the rapid clamping and fixing of the workpiece, thereby completing the upper and lower clamping and fixing of the workpiece.
[0027] After the workpiece is clamped and fixed on the left and right, it is necessary to clamp and fix the workpiece up and down, through the fixing block 4, pull the pull rod 5 inside the clamp 3, and then drive the clamping plate 6 to pull through the pull rod 5, and then squeeze the clamp 3 inside the clamp 3, and then put the workpiece into the inside of the clamp 3. Now, release the hand holding the fixing block 4. At this time, the clamping plate 6 squeezes the clamping plate 6 through the spring 7 and the pull rod 5, and then the workpiece is clamped and fixed through the cooperation between the clamping plate 6 and the sponge pad 18. Compared with the traditional clamp, the clamp facilitates the rapid clamping of the workpiece through the cooperation between the clamping plate 6 and the spring 7, ensures that the workpiece maintains a stable position and state during processing, avoids displacement and deformation, thereby significantly improving the processing accuracy and product quality. The high stability and rigidity of the clamp provide sufficient fixing force to ensure the accurate position and size of the workpiece during processing. At the same time, the clamp can also quickly locate, support and guide the workpiece, reduce manual adjustment time, greatly improve work efficiency, and reduce production costs.
[0028] A limiting groove 15 is provided inside the workbench 1 , and a limiting block 17 is movably installed inside the limiting groove 15 , and a tool box 16 is fixedly installed on the front side of the limiting block 17 .
[0029] By holding the limit block 17, the limit block 17 is fixed on the front of the tool box 16, and then the tool box 16 and the limit block 17 are slowly placed into the limit groove 15, and the tool box 16 and the limit block 17 are fixed through the limit groove 15. The internal integration of the tool box 16 allows commonly used tools and equipment to be accessed anytime and anywhere, reducing the time for finding and replacing tools during the processing process, thereby improving the overall work efficiency.
[0030] A support seat 13 is fixedly installed at the bottom of the workbench 1 , and a base 14 is fixedly installed at the bottom of the support seat 13 . The support seats 13 and the base 14 are arranged in groups of two, and there are four groups at the bottom of the workbench 1 .

[0034] Wherein, a sponge pad 18 is fixedly installed on the bottom of the clamping plate 6, and the sponge pad 18 is made of natural rubber material.
[0035] Since the sponge pad 18 is made of natural rubber, and the natural rubber sponge pad 18 material has excellent elasticity and softness, it can effectively relieve pressure and provide good comfort. At the same time, it has strong anti-slip performance, high stability, and strong durability, and can be used for a long time in a variety of environments. This ensures that the workpiece is clamped more stably through the cooperation between the sponge pad 18 and the clamping plate 6, thereby improving the clamping efficiency of the workpiece.

[0037] The staff needs to use the clamp 3 to clamp and fix the workpiece to the left and right, by opening the support block 9, and driving the gear 1 11 to rotate through the support block 9, and through the meshing between the gear 11 and the gear 2 12, the gear 1 11 drives the gear 2 12 to rotate, and the gear 2 12 drives the two-way screw 19 to rotate inside the workbench 1 and the threaded sleeve 2, and then drives the fixed round block 20 to rotate through the two-way screw 19, so that the threaded sleeve 2 slides inside the slide groove 8, and drives the two to the inside of the clamp 3, and the workpiece is clamped and fixed to the left and right through the cooperation of the two clamps 3, thereby completing the left and right clamping and fixing of the workpiece.
[0038] After the staff has completed the left and right clamping of the workpiece, it is necessary to clamp and fix the workpiece up and down, through the fixing block 4, pull the pull rod 5 inside the clamp 3 through the fixing block 4, and then drive the clamping plate 6 to pull through the pull rod 5, and then squeeze the inside of the clamp 3 through the clamping plate 6, and then put the workpiece into the inside of the clamp 3. Now, let go of the fixing block 4. At this time, the clamping plate 6 squeezes the clamping plate 6 inside the clamp 3 through the spring 7 and the pull rod 5, and the cooperation between the clamping plate 6 and the sponge pad 18 facilitates the rapid clamping and fixing of the workpiece, thereby completing the upper and lower clamping and fixing of the workpiece.
