The output end of the motor 42 is connected to a positive and negative lead screw 43, and first lead screw sleeves 44 are screwed on both sides of the middle part of the positive and negative lead screws 43. Guide frames 45 are fixedly mounted on the inner side of the two first lead screw sleeves 44, and guide sleeves 46 are fixedly mounted on the other end of the two guide frames 45. A guide rod 47 is fixed in the middle of the fixed block 41, and a clamping frame 48 is fixed above the two guide frames 45. The guide frame 45 is connected to the guide rod 47 by the guide sleeve 46. The operator can start the motor 42 in advance to make the positive and negative lead screws 43 rotate. The two first lead screw sleeves 44 that interact with the lead screws will carry the fixed guide frames 45 and clamping frames 48 to move relative to each other in coordination with the guide sleeves 46 and guide rods 47. During this process, the operator can place the hardware to be processed in the middle of the two clamping frames 48 and form a stable clamp. Then, the machine head assembly 3 can be used to perform CNC processing on the clamped hardware.

[0028] The protection mechanism 5 comprises an assembly frame 51 fixed to the top of one side of the main body 1, and a lifting assembly 52 is installed in the interior of the assembly frame 51. The lifting assembly 52 comprises a double-head motor 521 installed in the middle section of the interior of the assembly frame 51, and transmission rods 522 are connected to the two ends of the double-head motor 521. A first bevel gear 523 is fixed to a section of the periphery of each transmission rod 522, and a second bevel gear 524 is engaged on one side of each first bevel gear 523. The first bevel gears 523 and the second bevel gears 524 are in meshing transmission connection with each other, and transmission lead screws 525 are fixed to the middle sections of the two second bevel gears 524.

The guide frames 527 are in movable guiding connection with cover frames 53, and the cover frames 53 are fixed to the inner sides of the two second lead screw sleeves 526. Sound insulation assemblies 54 are installed in the inner sides of the cover frames 53. The sound insulation assemblies 54 comprise clamping grooves 541 formed in the bottom ends of the cover frames 53, and sound insulation cotton 542 is arranged in the inner sides of the cover frames 53.
