[0053] Through the above settings, the return spring 220 is fixed in the cylinder body 210, and the clamping member 230 for clamping the marker pen 3 is arranged at the end of the return spring 220, so as to achieve the effect of automatic reset of the marker pen 3.

[0054] Specifically, a sleeve 310 is arranged at the end of the marker pen 3, and the clamping member 230 is also in a cylindrical structure as a whole. The clamping member 230 is embedded in the sleeve 310 to realize the clamping between the marker pen 3 and the clamping member 230.

[0055] Preferably, the clamping member 230 is axially provided with a plurality of long strip-shaped notches, and the clamping member 230 can be slightly contracted and deformed under pressure, which is convenient for the clamping member 230 to be embedded in the sleeve 310.

[0056] Preferably, anti-slip grooves 231 are provided on the outer peripheral surface of the clamping member 230 for embedding the sleeve 310 to ensure a firm connection between the clamping member 230 and the marker pen 3.

[0057] Furthermore, a threaded hole is provided at one end of the clamping member 230 facing away from the marker pen 3. The return spring 220 is connected to the clamping member 230 by a screw 250 screwed into the threaded hole. A limiting gasket 260 is also provided between the screw 250 and the clamping member 230 to ensure the firm connection of the screw 250.

[0058] Preferably, the clamping member 230 is integrally installed in the barrel 210. An axial travel groove 213 is provided at the end of the barrel 210. A convex block 261 is protruded on the circumferential surface of the side part of the limiting gasket 260 corresponding to the travel groove 213. The convex block 261 and the travel groove 213 cooperate with each other, which can not only guide the movement of the limiting gasket 260 (which can also be regarded as the structure after the clamping member 230 and the limiting gasket 260 are connected together) in the barrel 210 for easy assembly, but also limit the farthest movement position of the limiting gasket 260 in the barrel 210 after the convex block 261 moves to the bottom of the travel groove 213.

A long strip-shaped notch is also provided at the end of the cylinder body 210 for assembling the cover body 240, so that the end of the cylinder body 210 can be slightly expanded and deformed outward. At the same time, the second elastic buckle 241 is also slightly bent inward, so that the second elastic buckle 241 on the outer peripheral surface of the cover body 240 can also be embedded in the cylinder body 210. Until the second elastic buckle 241 reaches the position of the through hole 211, the second elastic buckle 241 enters the through hole 211 to realize the quick connection between the cover body 240 and the cylinder body 210.

[0063] In one embodiment, please refer to Figures 2 to 4 , a connecting portion 212 is convexly provided on the outer peripheral surface of the pen cap 2. A first screw hole is provided on the mounting plate 130. A second screw hole is correspondingly provided on the connecting portion 212. The scribing and marking device 100 further includes a locking screw 4 screwed into the first screw hole and the second screw hole, so that the included angle between the pen cap 2 and the mounting seat 1 can be adjusted.

[0064] In this way, the staff can flexibly adjust the positional relationship between the marker pen 3 and the drill bit 300 according to the actual working conditions, with high flexibility.

[0065] In one embodiment, please refer to Figure 2 , a handle 410 is provided on the locking screw 4. The staff can directly rotate the locking screw 4 through the handle 410 without preparing additional tools.

[0066] According to another aspect of the present application, please refer to Figure 1 together.
