the clamping area 21 comprises a clamping area mounting plate 21g, a clamping area 21a, a clamping support 21b, a fulcrum 21c, a tension spring 21f, a first torsion spring 21d and a second torsion spring 21e, and the lower end of the clamping area mounting plate 21g is provided with the clamping area 21a, the clamping support 21b, the fulcrum 21c, the tension spring 21f, the first torsion spring 21d and the second torsion spring 21 e;

the reaction vessel is cylindrical, the gripper 21a is R-shaped, the radius of the gripper 21a is smaller than that of the reaction vessel, and the pressing part of the gripper 21a is positioned at the outer side position of the center of the reaction vessel, so that the reaction vessel can be stably gripped;

the clamp 21a rotates around a pivot 21c, and presses the reaction vessel with a constant force by a first torsion spring 21d and a second torsion spring 21e, and the clamp bracket 21b has the function of a connecting rod;

the pressure of the first torsion spring 21d and the second torsion spring 21e enables the clamping position of the reaction container to be stable, and the tension spring 21f is the pressure of the auxiliary torsion springs 21d and 21 e;

the gripping operation area 22 includes a cam 22a, a motor 22b, and a carriage 22 c;

the cam 22a is positioned in the middle of the gripping bracket 21b, the gripping bracket 21b rotates by the torsion spring 21d, the torsion spring 21e and the tension spring 21f with the fulcrum 21c as a rotation axis, the cam 22a is continuously pressed by the gripping bracket 21b, the cam 22a can freely rotate because the hole opened at the center is engaged with the shaft of the motor 22b, the motor 22b is mounted on the bracket 22c,

the gripping state detection area 23 includes a detection plate 23a, a first sensor 23b, a second sensor 23c and a sensor mounting plate 23d,

the detection plate 23a is arranged on the clamping bracket 21b with weak pressure, the detection plate 23a is arranged on a sensor mounting plate 23d at a detectable position, the first sensor 23b and the second sensor 23c are transmission type sensors arranged in a light projection area and a back light receiving area, the sensors are opened if light from the light projection position is received at the light receiving position, and the sensors are closed if light from the light projection position is not received at the light receiving position due to a shielding object;

when the motor 22b is rotated and the gripper 21a grips and releases the reaction vessel, there are 3 positional relationships, and the operations of the respective zones and the detection states of the first sensor 23b and the second sensor 23c will be described below;

first, the motor 22b rotates, the clamping brackets 21b of the two sides are pressed by the cylinder area outside the cam 22a, the clamping 21a is in the maximum opening state, the torque of the motor 22b is larger than the torque generated by the first torsion spring 21d, the second torsion spring 21e and the tension spring 21f, therefore, the clamping detection plate 21a can be opened to the maximum extent, and at the moment, the light of the first sensor 23b and the second sensor 23c can be shielded by the first motor 23 a;

secondly, the outer cylinder area presses the clamping support 21b to enable the cam 22a to rotate 90 degrees, the cam 22a is displaced to the inner cylinder area at the position of the clamping support 21b with strong pressure, the cam 22a is displaced to the cutting area at the position of the clamping support 21b with weak pressure, the relative relation between the clamping support 21a and the reaction container is not changed all the time as the clamping support 21b with strong pressure is displaced to the position connected with the inner cylinder area of the cam 22a, in addition, the clamping support 21a is always pressed against the reaction container before the clamping support 21b with weak pressure reaches the cutting area of the cam 22a, and the pressure is smaller than the clamping support 21a on the back, so the position of the reaction container is stable, and at the moment, no light is blocked by the sensor two 23c and the sensor one 23b due to the gap of the detection plate 23 a;

thirdly, because the clamping support 21b with strong pressure moves to a position connected with a cylindrical area on the inner side of the cam 22a, the relative relationship between the clamping support 21a and the reaction vessel is not changed all the time, in addition, the clamping support 21b with weak pressure reaches a cutting area of the cam 22a, the sensor two 23c does not block light, and the sensor one 23b blocks light because the optical axis of the projected light and the received light deviates from the gap of the detection plate 23 a;

the gripping movement area 24 includes a linear guide rail 24a, a linear pulse motor 24b, a rotation shaft 24c, a spring three 24d, and a spring four 24 f;

a gripping area mounting plate 21g on which the gripping area 21, the gripping operation area 22, and the gripping state detection area 23 are mounted is mounted on the linear guide rail 24a, the gripping area mounting plate 21g is connected to the shaft portion of the linear pulse motor 24b through a rotation preventing shaft 24c, a portion of the shaft of the linear pulse motor 24b has a place cut into 2 planes, the rotation preventing shaft 24c is provided in the cutting area, the thickness of the rotation preventing shaft 24c is slightly smaller than the width of the place where the shaft portion of the linear pulse motor 24b is cut into 2 planes, and thus a rattling sound occurs when moving, a linear pulse motor mounting plate is provided with a spring three 24d and a spring four 24f for eliminating rattling, and the sensor area 25 includes origin sensors 25a and 25b of a transmission type;

moving the reaction vessel from the first clamping position 42 on the feeding hopper area 11 to the second clamping position 43 on the reaction tray 3, rotating the transfer mechanism 10 to the first clamping position 42 where the reaction vessel is placed according to the adjustment value of the first clamping position 42 by an instruction, moving the transfer mechanism 10 back and forth according to the adjustment value of the first clamping position 42, performing the next operation according to another instruction, opening the clamping position 21a to the maximum, lowering the transfer mechanism 10, performing the clamping operation, raising the transfer mechanism 10 to the top dead center, moving the reaction vessel to the second clamping position 43, rotating the transfer mechanism 10 according to the adjustment value of the second clamping position 43, moving the reaction vessel back and forth according to the adjustment value of the second clamping position 43, lowering the transfer mechanism 10, opening the clamping position 21a to the maximum, placing the reaction vessel on the reaction tray 3, moving the reaction vessel to a designated place by the transfer device 14 according to the measurement step, and finally, after the light measurement of the light measurement area 13 is finished, the reaction container is moved to a reaction container recovery area 12 for recovery.
