The main body of the cutting motor 513 is fixedly connected in the motor frame 514. The cutting motor 513 is electrically connected to the control main board 103.

[0044] Its working principle is as follows:

[0045] The present invention uses an array of support feet 102 in the base component 1 to place the feet on the operating plane;

[0046] Based on the distance between each group of fins in the copper tube sample 6 to be cut, the spacing between each group of fixed inner clamps 204 and the spacing between each group of movable inner clamps 305 are adjusted synchronously:

[0047] Loosen the array locking screw 211 with a standard tool to eliminate the downward pressing force of the locking wedge 209 on the array fixing clamp rod 203, so that the array fixing clamp rod 203 can slide freely laterally in the fixing clamp rear slide 205;

[0048] By manually moving the fixing clamp rods 203, the distance between the array of fixing clamp rods 203 corresponds to the fin spacing of the outer fin copper tube sample 6 to be cut;

[0049] Since the inner sliding bottom surface of the fixed clamp rear slide 205 is evenly provided with an array of adjustment positioning holes 212, and the distance between the fins of the outer fin copper tube sample 6 is a multiple of the distance between the array of adjustment positioning holes 212, the main body of the fixed clamp rod 203 and the fixed clamp slider 206 is vertically and springily connected with an adjustment spring 214. Under the action of the spring spring 215 on the adjustment spring 214, each set of fixed clamp rods 203 and fixed inner clamps 204 can move precisely to the position corresponding to the fin spacing of the outer fin copper tube sample 6, ensuring that the inner arc surface of the array of fixed inner clamps 204 can be in contact with the non-fin surface of the outer fin copper tube sample 6.

[0050] At the same time, while each set of fixed clamp rods 203 moves laterally, the fixed clamp rods 203 drive the corresponding moving connecting arm 402 and moving clamp rod 306 to move laterally through the fixed connecting arm 401, so as to realize the synchronous lateral adjustment of each set of moving inner clamps 305 and the corresponding fixed inner clamps 204, and realize the contact with the non-finned front and rear surfaces of the outer finned copper tube sample 6.

[0051] After the lateral spacing between the fixed inner clamp 204 and the corresponding movable inner clamp 305 is adjusted, the outer finned copper tube sample 6 can be clamped.

[0052] First, place the non-finned rear surface of the outer finned copper tube sample 6 against the array of fixed inner clamps 204. Then, start the lead screw motor 313 by operating the operation button 104, which drives the rotation of the moving lead screw 312. The moving lead screw 312 and the sliding lead screw slide 303 form a transmission, which drives the sliding lead screw slide 303 and the moving outer clamp 301 to move towards the fixed outer clamp 201.

[0053] The moving outer clamp 301 drives the array of moving inner clamps 305 to move towards the non-finned front surface of the outer finned copper tube sample 6. The clamping force between the array of moving inner clamps 305 and the corresponding fixed inner clamps 204 clamps the outer finned copper tube sample 6. By clamping the non-finned surface of the outer finned copper tube sample 6, the outer finned copper tube sample 6 can be clamped stably and in a standard manner without damaging the fins of the outer finned copper tube sample 6.

[0054] Cutting of copper tube sample 6 with external fins:

[0055] By operating the control button 104, the cutting motor 513 is started, which drives the cutting shaft 509 to rotate at high speed, and the cutting shaft 509 drives the cutting saw blade 511 to rotate at high speed.

[0056] At this time, by pressing down on the front end of the cutting rod 503, the high-speed rotating cutting saw blade 511 is driven to move downward, thus completing the cutting of the outer finned copper tube sample 6.

[0057] Preferably, a return torsion spring 504 is sleeved on the outer end of the cutting shaft 502, and a torsion spring cover 505 is fixedly connected to the top surface of the outer end of the cutting shaft 502 to prevent the return torsion spring 504 from falling out of the cutting shaft 502. A torsion spring retainer 506 is fixedly connected to the top surface of the base 101 at the position corresponding to the return torsion spring 504. A torsion spring coupling retainer 507 is fixedly connected to the side of the cutting main rod 503 at the position corresponding to the return torsion spring 504. One end of the return torsion spring 504 is locked in the torsion spring retainer 506, and the other end is locked in the torsion spring coupling retainer 507. Under the elastic force of the return torsion spring 504 on the cutting main rod 503 through the torsion spring coupling retainer 507, the cutting main rod 503 can be in an upward-lifted state in its natural state.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
