[0021] The calibration mechanism 2 includes a slide groove 201, a connecting groove 202, a slider 203, a screw 204, a nut 205, a moving plate 206, a connecting plate 207, a connecting rod 208, a drum 209, a connecting wire 210, a lead block 211, a rotating block 212, a limiting groove 213, a connecting block 214, and a limiting block 215. A slide groove 201 and a connecting groove 202 are formed on one side of the base 1. A slider 203 is disposed inside the slide groove 201, and a screw 203 is welded to one side of the slider 203. 4. A nut 205 is threaded onto one end of the screw 204. A movable plate 206 is fixedly connected to one side surface of the slider 203. A connecting plate 207 is fixedly connected to one side surface of the movable plate 206. A connecting rod 208 is provided at one end of the connecting plate 207. A drum 209 is fixedly installed on the outer wall of the connecting rod 208. A connecting wire 210 is wound around the outer wall of the drum 209. A lead block 211 is fixedly connected to one end of the connecting wire 210. A rotating block 212 is fixedly installed at one end of the connecting rod 208. A rotating block 212 is fixedly installed on one side surface of the rotating block 212. A limiting groove 213 is provided, and a connecting block 214 is fixedly installed on one side surface of the connecting plate 207. A limiting block 215 is provided at one end of the connecting block 214. Through the setting of the sliding groove 201, connecting groove 202, slider 203, screw 204, nut 205, moving plate 206, connecting plate 207, connecting rod 208, drum 209, connecting line 210, lead block 211, rotating block 212, limiting groove 213, connecting block 214 and limiting block 215, when performing the calibration work, first loosen the nut 205 and pull. Move the movable plate 206. At this time, the slider 203 slides in the slide groove 201, which drives the movable plate 206 to move at one end of the base 1, thereby moving the lead block 211 to a suitable calibration position. After reaching the suitable position, tighten the nut 205 to fix it. Then lift the limit block 215 and rotate the connecting rod 208. The connecting rod 208 will drive the drum 209 to rotate. The connecting wire 210 wound on the surface of the drum 209 will drive the lead block 211 to descend. The calibration work can be carried out quickly and accurately. The operation is simple and convenient and the calibration accuracy is high.

[0022] Furthermore, the slider 203 forms a sliding structure with the base 1 through the slide groove 201. One end of the screw 204 passes through the connecting groove 202 and is threadedly connected to the nut 205. With the setting of the slide groove 201 and the slider 203, when the slider 203 slides in the slide groove 201, it can drive the moving plate 206 to move on the upper end of the base 1, so that the lead block 211 can be moved to a suitable calibration position.

[0023] Furthermore, the connecting rod 208 is connected to the connecting plate 207 via a bearing, and the rotating block 212 forms a rotating structure with the connecting rod 208 and the connecting plate 207. Through the setting of the connecting rod 208, the connecting rod 208 can drive the drum 209 to rotate, and perform winding and unwinding work on the connecting line 210.

[0024] Furthermore, the limiting block 215 is connected to the connecting block 214 via a bearing. The limiting block 215 and the connecting block 214 form a rotating structure. By setting the limiting block 215, the limiting block 215 can limit the rotation of the connecting rod 208 and the drum 209, thereby fixing the position of the lead block 211.

[0025] Furthermore, the fixing mechanism 3 includes a fixing block 301, a slot 302, a fixing seat 303, a receiving groove 304, a spring 305, a locking block 306, a pull rod 307, and a fixing film 308. A fixing block 301 is fixedly installed on one side surface of the base 1. Slots 302 are formed on both sides of the fixing block 301. One end of the fixing block 301 is connected to the fixing seat 303. A receiving groove 304 is formed on the inner wall of the fixing seat 303. A spring 305 is fixedly installed inside the receiving groove 304. One end of the spring 305 is fixedly connected to the locking block 306. A pull rod 307 is fixedly connected to one side surface of the locking block 306. A fixing film 308 is provided at the bottom of the fixing seat 303. The fixing mechanism 301, slot 302, and fixing seat 303... The arrangement of the receiving groove 304, spring 305, locking block 306, pull rod 307, and fixing film 308 allows for the following setup: Before calibration, the fixing base 303 is fixedly installed in its self-positioning position using the fixing film 308. Then, the fixing block 301 is placed into the fixing base 303. When the fixing block 301 enters the fixing base 303, it will press the locking block 306 into the receiving groove 304. When the fixing block 301 is fully inside the fixing base 303, the locking block 306 is no longer compressed, and the spring 305 will drive the locking block 306 to return to its original position. The returned locking block 306 will enter the locking slot 302, thus fixing the fixing block 301 in the fixing base 303 and fixing the base 1 in the designated position. The installation is simple and stable, improving the accuracy of calibration.

[0026] Furthermore, the card slot 302 and the card block 306 are sized to match. The card block 306 and the fixing block 301 form a locking structure through the card slot 302. With the setting of the card slot 302 and the card block 306, when the card block 306 enters the card slot 302, the fixing block 301 is fixed in the fixing seat 303.

[0027] Furthermore, the locking block 306 forms a telescopic structure with the fixing base 303 via the spring 305. The fixing film 308 is double-sided adhesive. With the setting of the spring 305, the spring 305 can drive the locking block 306 to return to its original position, allowing the locking block 306 to smoothly enter the locking slot 302.

[0028] Working principle: During calibration, first loosen nut 205 and pull moving plate 206. At this time, slider 203 slides in groove 201, causing moving plate 206 to move at one end of base 1, thereby moving lead block 211 to the appropriate calibration position. Once the appropriate position is reached, tighten nut 205 to fix it. Then, lift limit block 215 and rotate connecting rod 208. Connecting rod 208 will drive drum 209 to rotate, and connecting wire 210 wound on the surface of drum 209 will cause lead block 211 to descend. This allows for quick and accurate calibration, is simple and convenient to operate, and provides high calibration accuracy. Before operation, the fixing base 303 is fixedly installed in the self-positioning position using the fixing film 308. Then, the fixing block 301 is placed into the fixing base 303. When the fixing block 301 enters the fixing base 303, it will squeeze the locking block 306 into the receiving groove 304. When the fixing block 301 is fully inserted into the fixing base 303, the locking block 306 is no longer squeezed, and the spring 305 will drive the locking block 306 to return to its original position. The returned locking block 306 will enter the locking groove 302. In this way, the fixing block 301 is fixed in the fixing base 303, and the base 1 is also fixed in the designated position. The installation is simple and stable, which improves the accuracy of the calibration.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
