detailed description

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

A pen changing device for slate engraving, as shown in Figures 1-5, includes a front plate 11, a rear plate 12, a turntable 13, a connecting bracket 14, a pen cover 15, a marking pen 16 and an actuator 17. The plate 11, the turntable 13 and the rear plate 12 are arranged in parallel in sequence, and the front plate 11 and the rear plate 12 are fixed by the connecting bracket 14. The surface of the front plate 11 is provided with an annular protrusion 111. The pen cover 15 is radially provided with an opening 112, and the side wall of the opening 112 is provided with a first slope 113 that guides the rotation of the pen cover; the turntable 13 is provided with a number of mounting parts 131 in the circumferential direction, and the pen cover 15 is rotated and arranged on the mounting parts 131, so that the pen cover 15 is in the The turntable 13 is switched between the retracted state and the scribed state; the rear plate 12 is radially protruded with a limit block 121 , when the pen sleeve 15 is rotated between the opening 112 and the limit block 121 , the pen sleeve 15 is restricted along the axial direction of the turntable 13 . turn. The actuator 17 is disposed on the front plate 11 or the rear plate 12 , the actuator 17 is a stepping motor, and the stepping motor drives the turntable 13 to rotate. The scribing pen 16 is detachably arranged in the pen case 15 .

In one embodiment, as shown in Figs. 1-5, a side wall of the limiting block 121 is provided with a second inclined surface 122 for guiding the rotation of the pen cover 15. When the scribing pen is switched, the turntable 13 rotates, and the pen cover 15 close to the limiting block 121 is guided by the second inclined surface to rotate from the retracted state to the scribing state.

In one embodiment, as shown in FIGS. 1-5 , the actuator 17 is fixedly arranged on the rear panel 12 , and the connecting bracket 14 includes a first connecting portion 141 , a second connecting portion 142 and connecting the first connecting portion 141 and the first connecting portion 141 .
