Specifically, a fixing frame 115 is provided on the front and rear sides of the base 110, and two first stepper motors are respectively fixed to the fixing frames 115 on the front and rear sides by bolts. The two first stepper motors can be communicated and connected and move synchronously, and the rotation directions of the output shafts of the two first stepper motors can be opposite, that is, when the first stepper motor on the front side drives the first lead screw 123 on the front side to rotate forward through the telescopic coupling 122, the first stepper motor on the rear side drives the first lead screw 123 on the rear side to rotate forward through the telescopic coupling 122, so as to realize the same direction movement of the front and rear first lead screws 123.

It is worth noting that in the present embodiment, a stop flange 210 is further provided on the top side of the fixed beam 200. The stop flange 210 protrudes from the fixed beam 200 in the front-to-back direction. The first screw 123 and the second screw 152 are both located on the lower side of the stop flange 210, so that the stop flange 210 can prevent the base 110 from falling off the fixed beam 200.

It should be noted that the telescopic coupling in this embodiment has the function of telescoping in the front-to-back direction. The telescopic rod 1222 includes an outer cylinder 1225 and an inner cylinder 1224. The outer cylinder 1225 is sleeved outside the inner cylinder 1224, and the outer cylinder 1225 is connected to the first joint 1221, and the inner cylinder 1224 is connected to the second joint 1223.

The second lead screw 152 is arranged along the vertical direction. The rotation of the second lead screw 152 can drive the support platform 140 to rise or fall a certain distance.

In this embodiment, a fixed platform 131 is provided on both side edges of the mounting accessory 130, the second driving member 151 includes a second stepping motor and is fixedly disposed on the fixed platform 131, and the second adjusting positioning member 150 also includes a transmission gear set 153, the transmission gear set 153 is connected to the output shaft of the second stepping motor, and is transmission-connected to the second lead screw 152, so that the second stepping motor drives the second lead screw 152 to rotate through the transmission gear set 153.

It should be noted that in this embodiment, since the installation space at the installation accessory 130 is small, the second stepper motor can be installed horizontally, that is, the second stepper motor is arranged along the front-to-back direction. At this time, since the installation direction of the second stepper motor is not on the same straight line as the second lead screw 152, the transmission gear set 153 can adopt a bevel gear set to realize force transmission.

In this embodiment, the transmission gear set 153 includes a first bevel gear 1531 and a second bevel gear 1532. The first bevel gear 1531 is connected to the output shaft of the second stepper motor and driven by the second stepper motor.

In this embodiment, the third adjustment positioning member 160 includes a third driving member 161 and a driving gear 162. The third driving member 161 includes a third stepping motor. A supporting boss 148 is provided at at least one end of the transmission slider 145 along the third direction. The third stepping motor is fixedly mounted on the supporting boss 148. The driving gear 162 is disposed at the end of the third stepping motor and is transmission-connected with the output shaft of the third stepping motor. A transmission rack 147 is also disposed on the guide plate 144 along the third direction. The transmission rack 147 is disposed on one side of the boss guide rail 146. The driving gear 162 is meshed with the transmission rack 147.

It should be noted that in this embodiment, there is a certain gap between the transmission rack 147 and the sample carrier plate 143, and the width of the gap is greater than the outer diameter of the driving gear 162, so that the driving gear 162 can move freely in the gap. By providing the support boss 148, the interference between the third stepper motor and the driving gear 162 and the transmission slider 145 can be prevented, and the smooth installation of the third stepper motor is facilitated.

Specifically, the left and right ends of the transmission slider 145 are provided with support bosses 148, that is, the left and right ends of the transmission slider 145 are provided with third stepper motors, and the installation directions of the left and right third stepper motors are opposite, and the two third stepper motors are synchronously operated to ensure that the torque generated on both sides of the third stepper motor driving the driving gear 162 to rotate cancels each other, thereby ensuring smooth movement and avoiding jamming.

Referring to FIG. 9 , in this embodiment, a material blocking plate 170 is provided at both ends of the sample carrier plate 143. The material blocking plate 170 is elastically hinged with the end face of the sample carrier plate 143 and is used to elastically block the end face opening of the sample slot 141 to limit the end face of the core. Specifically, a material blocking shaft 171 is provided at the edge of the material blocking plate 170, and a material blocking lug 172 is provided at the end face of the sample carrier plate 143. The material blocking shaft 171 is rotatably assembled on the material blocking lug 172, and an elastic torsion spring 173 is sleeved on the material blocking shaft 171. The elastic torsion spring 173 provides elastic force to block the material blocking plate 170 on the end face opening with respect to the material blocking shaft 171. By providing the material blocking plate 170, the end face of the core sample can be elastically limited, and for a shorter core sample, the end face opening can be completely blocked to prevent particles or impurities from falling and polluting the experimental environment.

Please refer to Figures 10 and 11. In some embodiments, the edges of both sides of the sample slot 141 are also provided with positioning buckles 117. The positioning buckles 117 can be rotated and buckled on the edges of the sample slot 141, so as to limit the edge of the core sample in the sample slot 141 and prevent the core sample from being displaced. Among them, the positioning buckle 117 can include a buckle piece and a rotating shaft, the rotating shaft is fixedly arranged on the base, and the buckle piece can be rotatably assembled on the rotating shaft and can rotate with damping. When the sample is actually loaded, the core sample can be loaded into the sample slot. Since the core sample is usually installed in a semi-cylindrical plastic tube, the buckle piece can be selected after loading, so that the buckle piece is buckled and limited to the edge of the core sample, so as to limit the core sample and ensure the fixing effect. When the core sample needs to be removed, it is only necessary to rotate the buckle piece in the opposite direction to release the limit of the core sample, which is very convenient.
