[0029] Embodiment 1

[0030] Refer to Figures 1-4 , which is the first embodiment of the present utility model, and provides a star sleeve depth measuring instrument. This star sleeve depth measuring instrument includes a base 1. Support columns 10 are fixedly connected to the four corners of the lower surface of the base 1. A fixing assembly 3 is fixedly connected to the upper surface of the base 1 near the center. A measuring assembly 2 is fixedly connected to the upper surface of the fixing assembly 3 near the center

[0031] The measuring assembly includes a limit post 202 fixedly connected to the fixing assembly 3. Sliding grooves 203 are opened on both sides of the outer wall of the limit post 202 near the bottom end. A connecting plate 205 is slidably connected to the sliding grooves 203 near the center. Sliding rings 213 are fixedly connected to both ends of the connecting plate 205. Rotating shafts 214 are rotatably connected to both sides of the sliding rings 213. The other ends of the rotating shafts 214 are rotatably connected to a pointing plate 212. By placing the star sleeve into the sliding groove 203, the sliding ring 213 is lifted upward, and at the same time, the pointing plate 212 is turned outward, and the side of the pointing plate 212 is pressed against the star sleeve

[0032] A second magnet 211 is fixedly connected to the inner side of the pointing plate 212 near the upper end. A first magnet 201 is fixedly connected to both sides of the outer wall of the limit post 202 near the upper end. The first magnet 201 is attached to the second magnet 211. When the sliding ring 213 moves upward, the first magnet 201 is separated from the second magnet 211, so that the pointing plate 212 can be turned outward. At the same time, the pointing plate 212 can be fixed to the outer wall of the limit post 202 by the attachment of the first magnet 201 and the second magnet 211

[0033] At both ends of the bottom of the connecting plate 205, there are two second sliding bars 209 fixedly connected. Inside the second sliding bars 209, there are multiple second gear racks 210 fixedly connected. Near the center of the outer edge of the second gear racks 210, there is a gear 207 meshed. At both ends of the gear 207, they are fixedly connected to both sides of the sliding groove 203. The second sliding bars 209 are driven by the gear 207 to slide on the inner wall of the limiting column 202.

[0034] On the inner wall of the sliding groove 203 near the bottom end, there is a first sliding bar 208 slidably connected. On the side of the first sliding bar 208, there are multiple first gear racks 206 fixedly connected. Near the lower edge on the other side of the first sliding bar 208, there is a pressing ring 204 fixedly connected. The outer edge of the first gear racks 206 is meshed with the gear 207. When the star-shaped sleeve is placed into the limiting column 202, it moves downward to push the pressing ring 204 downward. While moving, when driving the first sliding bar 208 to move downward, it drives the second sliding bar 209 at the other end of the gear 207 to slide upward.

[0035] During the use process, by placing the star-shaped sleeve into the limiting column 202, the extrusion plate 32 drives the first sliding bar 208 to move downward. While moving, it drives the gear 207 to push the second sliding bar 209 upward, making the sliding ring 213 slide upward, so that the second magnet 211 above the pointing plate 212 is disengaged from the first magnet 201 above the limiting column 202. At the same time, through the rotating shaft 214, the pointing plate 212 is turned outward and pressed on the upper surface of the star-shaped sleeve, making the top end of the pointing plate 212 point to the scale line 12, and the depth of the star-shaped sleeve is measured by the two pointing plates 212 on both sides.

[0036] Embodiment 2

[0037] Refer to Figures 1-5 , which is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that the fixing component 3 includes a fixing base 30 fixedly connected to the base 1. On the upper surface of the fixing base 30, there are multiple rotating grooves 31 opened. At the top end of the rotating grooves 31, there is a threaded column 33 rotatably connected. At the other end of the threaded column 33, there is a turning handle 35 fixedly connected, and the threaded column 33 is rotated by turning the turning handle 35.

[0038] On the outer wall of the threaded column 33, there is a rotating part 34 rotatably connected. On the upper surface of the rotating part 34, there is an extrusion plate 32 fixedly connected. When the threaded column 33 rotates, the extrusion plate 32 is driven by the rotating part 34 to contract inward.

[0039] On the upper surface of the base 1 near both sides, there are two side plates 11 fixedly connected. Inside the side plates 11, there are scale lines 12 opened. The depth of the star-shaped sleeve is observed by turning the pointing plate 212 downward to point to the scale line 12.

[0040] During use, turn the screw column 33 by turning the knob 35. While turning, the rotating part 34 slides in the rotating groove 31, and at the same time drives the pressing plate 32 above the rotating part 34 to fix the star-shaped sleeve by using the pressing plate 32. Multiple knobs 35 can be turned individually to fix star-shaped sleeves with different shapes.
