[0041] Reference Figures 3 to 6 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that: the sliding portion 201 includes a sliding seat 201a arranged on the bottom plate 101, a sliding groove 201b arranged in the sliding seat 201a, and a sliding block 201c arranged in the sliding groove 201b; wherein the sliding seat 201a is fixedly arranged on the bottom plate 101, the sliding block 201c is slidably arranged in the sliding groove 201b, and two sliding blocks 201c are arranged.

[0042] The power unit 202 includes a threaded rod 202a disposed on the sliding seat 201a and connected to the sliding block 201c, opposite threads are disposed at both ends of the threaded rod 202a, and a motor 202b is disposed on the base plate 101 and connected to the threaded rod 202a; wherein the threaded rod 202a is rotatably disposed on the sliding seat 201a and is located in the sliding groove 201b, the threaded rod 202a is threadedly connected to the sliding block 201c, and the rotation of the threaded rod 202a drives the two sliding blocks 201c to move closer to or away from each other along the sliding groove 201b, and the output end of the motor 202b is fixedly connected to one end of the threaded rod 202a.

[0043] The correction part 203 includes a correction base 203a arranged on the sliding block 201c, a correction shaft 203b arranged on the correction base 203a, a correction plate 203c arranged on the correction shaft 203b, and a correction pad 203d arranged on the correction plate 203c; wherein, the correction base 203a is fixedly connected to the sliding block 201c by bolts, the correction shaft 203b is rotatably arranged on the end of the correction base 203a through a bearing, the correction plate 203c is fixedly arranged on the correction shaft 203b, a groove is opened at the end of the correction base 203a to provide space for the rotation of the correction plate 203c, the correction pad 203d is fixedly arranged on the correction plate 203c by bolts, and the correction pad 203d is made of rubber to prevent damage to the instrument connector 104b.

[0044] The guide portion 204 includes a guide plate 204a arranged on the support column 102a, and a guide protrusion 204b arranged on the guide plate 204a; wherein the guide plate 204a is fixedly arranged on the support column 102a, and two guide protrusions 204b are arranged symmetrically, which are used to open a limit groove 205 to prevent the limit groove 205 from contacting the support column 102a, thereby ensuring the normal use of the device.

[0045] The limiting groove 205 includes a lower transverse groove 205a arranged on the guide protrusion 204b, a vertical groove 205b arranged on the guide protrusion 204b and connected to the lower transverse groove 205a, and an upper transverse groove 205c arranged on the guide protrusion 204b and connected to the vertical groove 205b. The groove center of the upper transverse groove 205c is in the same horizontal plane as the axis center of the correction shaft 203b, and the lower transverse groove 205a, the vertical groove 205b and the upper transverse groove 205c are connected in a Z shape; wherein the lower transverse groove 205a is arranged horizontally, and when the flip part 206 moves along the lower transverse groove 205a, the correction pad 203d can be kept The two ends of the ...

[0046] Furthermore, the center of the upper transverse groove 205c and the axis of the correction shaft 203b are in the same horizontal plane, so that when the flip head 206c enters the upper transverse groove 205c, the flip head 206c just drives the correction shaft 203b to rotate 90 degrees, thereby turning the correction plate 203c to the horizontal. The lower transverse groove 205a, the vertical groove 205b and the upper transverse groove 205c are connected in a Z shape, and the corners are chamfered, which can effectively avoid jamming.

[0047] The flipping part 206 includes a flipping plate 206a disposed on the correction shaft 203b, the length of the flipping plate 206a is the same as the length of the vertical groove 205b, an extension rod 206b disposed on the flipping plate 206a, and a flipping head 206c disposed on the extension rod 206b and adapted to the lower horizontal groove 205a; wherein the flipping plate 206a is fixedly disposed at one end of the correction shaft 203b, the extension rod 206b is fixedly disposed on the flipping plate 206a, and the flipping head 206c is rotatably disposed on the extension rod 206b, which can reduce the flipping head 206c The friction between the flip head 206c and the limit groove 205 increases the smoothness of the device. When the flip head 206c approaches the chamfer a, the chamfer a transitions the flip head 206c to the vertical groove 205b to ensure the normal operation of the device. If the chamfer a is not set, when the flip head 206c moves to the chamfer a, the flip head 206c has no vertical component force, which may cause the flip head 206c to be stuck at the chamfer a. Through the setting of the chamfer b, not only the smoothness of the movement of the flip head 206c is guaranteed, but also the friction with the chamfer b is reduced, thereby increasing the service life of the device.

[0048] The remaining structure is the same as that of Example 2.

[0049] During use, after the pressure instrument 104 is placed in the placement part 103, the motor 202b is started to drive the threaded rod 202a to rotate. Since the two ends of the threaded rod 202a are opposite threads, the threaded rod 202a drives the two sliding blocks 201c to approach each other, and the sliding block 201c drives the correction base 203a to move the correction plate 203c, and the correction plate 203c drives the correction pad 203d to squeeze the instrument joint 104b, so that the instrument joint 104b is located in the middle position. When the correction pads 203d approach each other, the correction base 203a drives the correction shaft 203b to move the flip plate 206a, and the flip plate 206a drives the extension rod 206b to move the flip head 206c along the lower horizontal groove 205a, which can prevent the correction pad 203d from flipping;

[0050] After the instrument joint 104b is centered, the motor 202b is started to rotate the threaded rod 202a in the opposite direction, and the threaded rod 202a drives the sliding block 201c to move the correction base 203a and the correction pad 203d away from each other. When the correction base 203a drives the correction shaft 203b to move the flip head 206c to the end of the lower transverse groove 205a, the threaded rod 202a continues to rotate to drive the correction base 203a to move, and the correction base 203a drives the correction shaft 203b to move. Since the flip head 206c cannot continue to move after moving to the end of the lower transverse groove 205a, When the correction shaft 203b continues to move, the end of the lower horizontal groove 205a squeezes the flip head 206c to rotate the flip plate 206a. The rotation of the flip plate 206a drives the flip head 206c to move along the vertical groove 205b into the upper horizontal groove 205c. When the flip plate 206a rotates, it drives the correction shaft 203b to rotate the correction plate 203c. Therefore, when the flip head 206c enters the upper horizontal groove 205c, the correction plate 203c flips 90 degrees to a horizontal state, which not only facilitates the placement of the instrument joint 104b, but also increases the extrusion and leveling range of the correction pad 203d.
