[0017] The sliding mechanism 3 mentioned above is explained below. Figure 2 As shown, the sliding mechanism 3 includes: a slot plate 301, a slider 302, a screw rod 303 and a support block 304;
[0018] The slot plate 301 is fixedly arranged at the top of the front surface of the base 1, and the slot plate 301 is used to support the support block 304. The slider 302 is movably arranged inside the slot plate 301, and the slider 302 can limit the support block 304 when it slides. The screw 303 is threadedly arranged inside the outer side of the slot plate 301, and the support block 304 is fixedly arranged at the inner top of the slider 302, wherein the support block 304 can be fixed by the screw 303 after sliding inside the slot plate 301 through the slider 302. A sliding groove matching the slider 302 is opened inside the slot plate 301, and cavities are opened on both sides of the interior of the support block 304, and a semicircular groove is opened on the top.
[0019] The pressing mechanism 4 mentioned above is explained below. Figure 2 and Figure 3 as well as Figure 4 As shown, the pressing mechanism 4 includes: a spring 401, a vertical rod 402, a limit block 403, a connecting rod 404 and a pressing block 405;
[0020] The spring 401 is fixedly arranged inside the two sides of the support block 304, the vertical rod 402 is fixedly arranged at the top of the spring 301, the limit block 403 is fixedly arranged at the top of the vertical rod 402, the connecting rod 404 is fixedly arranged at the top of the limit block 403, the pressing block 405 is fitted at the top of the support block 304, and the two sides of the bottom end of the pressing block 405 are fixedly connected to the connecting rod 404, wherein, when the pressing block 405 is pressed downward, the limit block 403 is driven to move downward at the same time through the connecting rod 404 and the spring 401 is squeezed through the vertical rod 402, and a semicircular groove is opened at the bottom of the pressing block 405.
[0021] Working principle: When the centerless grinder for medical minimally invasive nickel-titanium guide wire is used, the user first controls the grinder 2 to start working through the external control unit, and then the user aligns the nickel-titanium guide wire from the front surface of the support block 304 with the semicircular groove and inserts it through the support block 304, and then the user adjusts the length of the nickel-titanium guide wire, and then the user presses the pressing block 405 downward, during which the pressing block 405 drives the connecting rod 404 to move downward and drives the limit block 403 to move downward inside the support block 304 at the same time, and then the limit block 403 moves downward and drives the vertical rod 402 to move downward at the same time and squeezes the spring 401 through the vertical rod 402 moving downward, and then when the pressing block 405 is completely fitted on the top of the support block 304, the nickel-titanium guide wire is fixed by the cooperation of the support block 304 and the pressing block 405, and then the user moves the pressing block 405 forward Push, when pushing, the slider 302 performs a limiting work on the movement of the support block 304 inside the groove plate 301.
