[0022] The terms "upper", "lower", "inner", "outer" and the like do not constitute absolute spatial relationship limit, but only a relative position concept. This is understood by those skilled in the art.

[0023] Embodiment 1

[0024] A measuring device for the center position of a pot mainly comprises a first measuring member 100 and a second measuring member 200, and the center points of the first measuring member 100 and the second measuring member 200 are rotatably connected together through a rotating shaft 300.

[0025] The first measuring member 100 and the second measuring member 200 are both left-right symmetrical structures. The first measuring member 100 and the second measuring member 200 both comprise a horizontal beam and vertical limiting legs arranged at both ends of the horizontal beam. The lower end of the rotating shaft 300 is provided with a laser emitter 310, and the direction of the laser emitter is also vertically downward (parallel to the vertical limiting legs). Of course, other emitters for emitting marking points can also be used.

[0026] The lower ends of the four vertical limiting legs of the first measuring member 100 and the second measuring member 200 are consistent in height, so as to ensure the stable placement of the device.

[0027] Taking the first measuring member 100 as an example, the horizontal beam 110 comprises a groove-shaped bracket base 111, a left connecting rod 112 and a right connecting rod 113. The groove-shaped bracket base 111 is a U-shaped groove structure with an open upper end, and the rotating shaft 300 passes through the center point of the groove-shaped bracket base 111, so as to ensure that the first measuring member 100 can rotate around the rotating shaft 300. The left and right connecting rods (112, 113) are both metal components, so as to ensure the strength. The left and right connecting rods (112, 113) are arranged in the groove 114 of the groove-shaped bracket base, and are respectively arranged on both sides of the rotating shaft 300.

[0028] Two groups of rolling shafts 115 (or other groups) are arranged between the left and right connecting rods (112, 113), and the two groups of rolling shafts 115 are distributed on both sides of the rotating shaft. One side edge of the left and right connecting rods (112, 113) is tightly attached to the corresponding groove edge of the groove-shaped bracket base, and the other side edge is tightly attached and pressed by the side edge of the rolling shaft.

[0029] When the left connecting rod 112 is pulled outwards, the right connecting rod 113 can perform a synchronous outward extension movement along the groove-shaped bracket base. When the right connecting rod 113 is pushed inwards, the left connecting rod 112 can perform a synchronous inward retraction movement along the groove-shaped bracket base.

[0030] The vertical limiting legs 116 at both ends of the horizontal beam are welded together with the horizontal beam.

[0031] When in use, the four vertical limiting legs are clamped around the pot, and the marking point (light spot) is emitted to the pot through the laser emitter 310, and the marking point displayed on the pot is the center point of the pot. The position of the light spot remains unchanged by rotating the positions of the first measuring member 100 and the second measuring member 200 for result verification.

[0032] When measuring other size pot, first adjust the length of left and right connecting rod (112, 113) to match the size of the pot, then four vertical limit legs are clamped around the pot, the center point of the pot is quickly and accurately found by the laser emitter 310, the structure is simple, and the operation is convenient.

[0034] A pot center position measuring device mainly comprises a first measuring part 100 and a second measuring part 200, and the center points of the first measuring part 100 and the second measuring part 200 are rotatably connected together through a rotating shaft 300.

[0035] The first measuring part 100 and the second measuring part 200 are left-right symmetrical structures. The first measuring part 100 and the second measuring part 200 each comprise a horizontal beam and vertical limit legs arranged at both ends of the horizontal beam, and the lower end of the rotating shaft 300 is provided with a laser emitter, and the direction of the laser emitter is also vertically downward (parallel to the vertical limit leg). The lower ends of the four vertical limit legs of the first measuring part 100 and the second measuring part 200 are consistent in height, so as to ensure the stable placement of the equipment.

[0036] The difference from the embodiment 1 is that, referring to Figure 3 , the left and right connecting rods are provided with a rack structure 410 on the opposite side, the rolling shaft is provided with a gear 420, and the rack structure 410 of the left and right connecting rods is engaged with the gear 420 of the rolling shaft. When the left connecting rod is pushed and pulled, the right connecting rod can perform synchronous extension and contraction movement along the groove-shaped support base.
