[0051] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0052] The embodiment of the utility model provides an angle adjustment device, referring to Figures 1 to 3 The angle adjustment device includes an adjustment base 100 and a first movable base 200. The adjustment base 100 has a first arc-shaped mating surface 110. The first movable base 200 is provided with a second arc-shaped mating surface 210 on the side facing the adjustment base 100. The first mating surface 110 fits with the second mating surface 210. The axes of the first mating surface 110 and the second mating surface 210 are parallel and parallel to the first direction. The first direction intersects with the second direction. The first movable base 200 can swing along the first mating surface 110 relative to the adjustment base 100. During the swinging process of the first movable base 200, the first mating surface 110 and the second mating surface 210 are always in contact with each other. The swinging of the first movable base 200 is guided by the first mating surface 110.

[0053] The angle adjustment device further includes a first adjustment component 400, which is used to drive the first movable seat 200 to swing relative to the adjustment base 100 and perform angle adjustment along the first mating surface 110. Specifically, the first adjustment component 400 includes a first adjustment shaft 410 and a first adjustment nut 420, the first adjustment nut 420 is threadedly connected to the first adjustment shaft 410, the first adjustment shaft 410 is passed through the adjustment base 100 along the second direction, and is rotatably connected to the adjustment base 100, one end of the first adjustment shaft 410 is located outside the adjustment base 100, the first adjustment nut 420 is slidably connected to the adjustment base 100 along the second direction, and abuts against the first movable seat 200 along the second direction. When the first adjusting shaft 410 is rotated, the first adjusting shaft 410 rotates relative to the adjusting base 100. Since the first adjusting nut 420 is threadedly connected to the first adjusting shaft 410 and the first adjusting nut 420 is guided by the sliding of the adjusting base 100, the first adjusting nut 420 can follow the rotation of the first adjusting shaft 410 and move along the second direction, and move the first movable seat 200 in the second direction, so that the first movable seat 200 swings around the first direction, thereby realizing the angle adjustment of the first movable seat 200 in the second direction; thus, the operator can realize the angle adjustment of the first movable base 200 relative to the adjusting base 100 by rotating the first adjusting shaft 410.

[0054] When the utility model is performing angle adjustment, the operator only needs to rotate the exposed end of the first adjustment shaft 410 to rotate the first movable seat 200 to achieve angle adjustment of the tissue sample, which is convenient to operate. The first adjustment component 400 converts the rotation input by the operator to the first adjustment shaft 410 into the swing of the first movable seat 200 through threaded transmission, which simplifies the structure of the angle adjustment device, and the first adjustment nut 420 moves smoothly, thereby achieving precise adjustment of the angle of the tissue sample.

[0055] It should be noted that the intersection of the first direction and the second direction means that in three-dimensional space, the first direction and the second direction are not parallel, the first direction and the second direction intersect, or the projections of the first direction and the second direction in the same plane have an intersection. In some embodiments, setting the first direction to be perpendicular to the second direction is more conducive to the calibration of the rotation angle of the sample tissue.

[0056] Furthermore, the angle adjustment device also includes a second movable seat 300, and the adjustment base 100 and the second movable seat 300 are respectively located on two opposite sides of the first movable seat 200, that is, the second movable seat 300 is located on the side of the first movable seat 200 facing away from the adjustment base 100, and the second movable seat 300 can be used for installing tissue samples; the first movable seat 200 is provided with a third arc-shaped mating surface 220 on the side facing the second movable seat 300, and the second movable seat 300 has a fourth arc-shaped mating surface 310, the third fitting surface 220 and the fourth fitting surface 310 are mutually fitted, and the axes of the third fitting surface 220 and the fourth fitting surface 310 are parallel and parallel to the second direction. The second adjustment component 500 is used to drive the second movable seat 300 to change relative to the first movable seat 200, and to adjust the angle along the third fitting surface 220.

[0057] The second movable seat 300 can swing relative to the first movable seat 200 along the third mating surface 220, and during the swinging process of the second movable seat 300, the third mating surface 220 and the fourth mating surface 310 are always in contact, the swinging of the second movable seat 300 is guided by the third mating surface 220, the swinging direction of the first movable seat 200 is perpendicular to the swinging direction of the second movable seat 300, and the angle of the tissue sample in different directions can be adjusted. The second adjustment component 500 includes a second adjustment shaft 510 and a second adjustment nut 520, the second adjustment nut 520 is screwed with the second adjustment shaft 510, the second adjustment shaft 510 is inserted into the first movable seat 200 along the first direction, and is rotatably connected to the first movable seat 200, one end of the second adjustment shaft 510 is located outside the first movable seat 200, the second adjustment nut 520 is slidably connected to the first movable seat 200 along the first direction, and is in contact with the second movable seat 300 along the direction. When the second adjusting shaft 510 is rotated, the second adjusting shaft 510 rotates relative to the first movable seat 200. Since the second adjusting nut 520 is threadedly connected to the second adjusting shaft 510 and the second adjusting nut 520 is guided by the sliding of the first movable seat 200, the second adjusting nut 520 can move along the first direction following the rotation of the second adjusting shaft 510 and move the second movable seat 300 in the first direction, so that the second movable seat 300 swings around the second direction, thereby realizing the angle adjustment of the second movable seat 300 in the first direction.

[0058] It can be understood that the second movable seat 300 can swing around the first direction relative to the adjustment base 100 following the first movable seat 200, and can swing around the second direction alone. The tissue sample installed on the second movable seat 300 can swing around the first direction and the second direction to achieve angle adjustment in the first direction and the second direction. When adjusting the angle, the operator only needs to rotate the exposed end of the first adjustment shaft 410 and / or the second adjustment shaft 510 to rotate the first movable seat 200 and the second movable seat 300 to achieve angle adjustment of the tissue sample in different directions. The operation is relatively convenient, and the first adjustment component 400 and the second adjustment component 500 both convert the rotation input by the operator to the first adjustment shaft 410 and / or the second adjustment shaft 510 into the swing of the first movable seat 200 and the second movable seat 300 through threaded transmission, simplifying the structure of the angle adjustment device, and the first adjustment nut 420 and the second adjustment nut 520 move smoothly, achieving precise adjustment of the angle of the tissue sample.

[0059] It should be noted that the first mating surface 110 and the second mating surface 210 have the same curvature, and when the first movable seat 200 rotates to different angles relative to the adjustment base 100, the second mating surface 210 always fits with the first mating surface 110; similarly, the third mating surface 220 and the fourth mating surface 310 have the same curvature, and when the second movable seat 300 rotates to different angles relative to the first movable seat 200, the third mating surface 220 always fits with the fourth mating surface 310. The first mating surface 110, the second mating surface 210, the third mating surface 220 and the fourth mating surface 310 can all be set as a part of a cylindrical surface with a preset radius value, and the axis of the first mating surface 110, the second mating surface 210, the third mating surface 220 and the fourth mating surface 310 is the axis of the cylindrical surface.

[0060] It is understandable that the bending directions of the first mating surface 110 and the second mating surface 210 are the same, that is, the first mating surface 110 and the second mating surface 210 protrude in the same direction, and similarly, the third mating surface 220 and the fourth mating surface 310 protrude in the same direction. In one embodiment, the first mating surface 110 and the second mating surface 210 protrude away from the second movable seat 300, and the third mating surface 220 and the fourth mating surface 310 protrude toward the second movable seat 300, which can fully utilize the internal space of the adjustment base 100 and the second movable seat 300, and is conducive to the light and thin design of the first movable seat 200; or, in another embodiment, the protruding directions of the first mating surface 110, the second mating surface 210, the third mating surface 220 and the fourth mating surface 310 are the same, and all protrude along the direction of the second movable seat 300 toward the adjustment base 100, so that the connection between the adjustment base 100, the first movable seat 200 and the second movable seat 300 is more compact and has a suitable structural strength.

[0061] The adjustment base 100 and the first movable base 200 are provided with first angle indicating scales that cooperate with each other and are used to indicate the rotation angle of the first movable base 200. For example, a pointer is provided on the adjustment base 100, and a plurality of scale lines are provided on the first movable base 200. The operator can learn the adjustment angle of the first movable base 200 according to the scale lines pointed by the pointer, which is conducive to accurate angle adjustment of the sample tissue; of course, a plurality of scale lines are also provided on the first movable base 200, and a pointer is provided on the adjustment base 100.

[0062] In addition, the first movable seat 200 and the second movable seat 300 are provided with second angle indicating scales that cooperate with each other and are used to indicate the rotation angle of the second movable seat 300. For example, a pointer is provided on the first movable seat 200, and a plurality of scale lines are provided on the second movable seat 300. The operator can learn the adjustment angle of the second movable seat 200 according to the scale line pointed to by the pointer; or, a pointer is provided on the second movable seat 200, and a plurality of scale lines are provided on the first movable seat 300.

[0063] The adjustment base 100 includes two first limiting walls 120 arranged at intervals, and the first limiting walls 120 are protruded toward the first movable seat 200 relative to the first mating surface 110, and the two first limiting walls 120 are respectively located on two opposite sides of the first movable seat 200 along the first direction; the two first limiting walls 120 can be limited to form a first limiting groove, and a part of the first movable seat 200 is movably connected in the first limiting groove. The first movable seat 200 is limited by the two first limiting walls 120 on two opposite sides of the first direction, so that the first movable seat 200 is swung around the first direction by the first adjusting nut 420, reducing the position deviation of the first movable seat 200 in other directions, and improving the position controllability of the first movable seat 200 during the angle adjustment process, and the first limiting walls 120 play a protective role for the first movable seat 200, reducing the possibility of external impurities and dust entering between the first mating surface 110 and the second mating surface 210.

[0064] Similarly, the first movable seat 200 includes two second limiting walls 230 arranged at intervals, and the second limiting walls 230 are protruded toward the second movable seat 300 relative to the third mating surface 220, and the two second limiting walls 230 are respectively located on the two sides opposite to each other along the second direction of the second movable seat 300; the two second limiting walls 230 can be limited to form a second limiting groove, and a part of the second movable seat 300 is movably connected in the second limiting groove, and the second movable seat 300 is limited by the two second limiting walls 230 on the two sides opposite to each other in the second direction, so that the second movable seat 300 is swung around the second direction by the second adjusting nut 520, thereby reducing the position deviation of the second movable seat 300 in other directions, and improving the position controllability of the second movable seat 300 during the angle adjustment process, and the second limiting walls 230 play a protective role for the second movable seat 300, reducing the possibility of external impurities and dust entering between the third mating surface 220 and the fourth mating surface 310.

[0065] The adjustment base 100 is provided with a guide structure for guiding the movement of the first adjustment nut 420 to constrain the first adjustment nut 420 to move only in the second direction. Similarly, the first movable seat 200 is provided with a guide structure for guiding the movement of the second adjustment nut 520 to constrain the second adjustment nut 520 to move only in the first direction. The guide structure can be a protruding structure provided on the first mating surface 110 or the third mating surface 220, and the first adjustment nut 420 or the second adjustment nut 520 is slidably connected to the protruding structure. Alternatively, in other embodiments, such as Figure 3 The adjustment base 100 has a first slide groove 130 extending along the second direction, the first adjustment nut 420 is slidably connected in the first slide groove 130, the outer wall of the first adjustment nut 420 is in sliding or rolling contact with the inner wall of the first slide groove 130, and the first slide groove 130 constrains the rotation of the first adjustment nut 420 in the circumferential direction, so that the first adjustment nut 420 can only move in the second direction following the rotation of the first adjustment shaft 410. Similarly, the first movable seat 200 has a second slide groove 240 extending along the first direction, the second adjustment nut 520 is slidably connected in the second slide groove 240, the outer wall of the second adjustment nut 520 is in sliding or rolling contact with the inner wall of the second slide groove 240, and the second slide groove 240 constrains the rotation of the second adjustment nut 520 in the circumferential direction, so that the second adjustment nut 520 can only move in the first direction following the rotation of the second adjustment shaft 510. In addition, the movement guidance of the first movable seat 200 and the second movable seat 300 is realized by setting a sliding groove, so that the connection between the adjustment base 100 and the first movable seat 200 and between the first movable seat 200 and the second movable seat 300 is more compact.

[0066] In addition, the adjustment base 100 is provided with a first mounting hole 140 extending along the second direction and connected to the first slide groove 130. The first adjusting shaft 410 is passed through the first mounting hole 140 and is screwed into the first adjusting nut 420. One end of the first adjusting shaft 410 is located outside the first mounting hole 140, and the end of the first adjusting shaft 410 located outside the adjustment base 100 is connected with a first operating cap 430 to facilitate the operator to rotate the first adjusting shaft 410. In addition, a shaft sleeve is provided in the first mounting hole 140, the first adjusting shaft 410 is passed through the shaft sleeve and is rotatably connected to the shaft sleeve, the shaft sleeve supports the first adjusting shaft 410 and allows the first adjusting shaft 410 to rotate smoothly. Similarly, the first movable seat 200 is provided with a second mounting hole 250 extending along the first direction and connected to the second slide groove 240. The second adjusting shaft 510 is passed through the second mounting hole 250 and is screwed to the second adjusting nut 520. One end of the second adjusting shaft 510 is located outside the second mounting hole 250, and the end of the second adjusting shaft 510 located outside the first movable seat 200 is connected to a second operating cap 530 to facilitate the operator to rotate the second adjusting shaft 510. A bushing is provided in the second mounting hole 250. The second adjusting shaft 510 is passed through the bushing and is rotationally intercepted with the bushing.

[0067] Further, such as Figure 2 and Figure 3 The first operating cap 430 is provided with a first rolling ball 431 at one end facing the adjusting base 100, and the side of the adjusting base 100 is provided with a first groove 150 ( Figure 2 The first groove 150 is located on the moving path of the first ball 431. During the rotation of the first operating cap 430, when the first ball 431 passes through the first groove 150, a part of the first ball 431 is embedded in the first groove 150, and the operator can feel the rotation resistance of the first operating cap 430 at this time. Therefore, the number of times the first ball 431 passes through the first groove 150 can indicate the number of rotations of the first operating cap 430. For each rotation of the first operating cap 430, the first movable seat 200 can rotate relative to the adjustable base 100 by a preset angle, so that the operator can more conveniently estimate the angle value currently adjusted by the first movable seat 200. In addition, a hole is provided inside the first operating cap 430, in which a spring is preset, one end of the spring is fixed inside the hole, and the other end is connected to the first ball 431, and a portion of the first ball 431 is exposed outside the first operating cap 430. Under the elastic force applied by the spring, a portion of the first ball 431 can be embedded in the first groove 150 and withdrawn from the first groove 150 under the drive of external force.

[0068] Similarly, the second operating cap 530 is provided with a second rolling ball 531 ( Figure 2 The second ball position in the figure is perspectively processed), a second groove 260 is provided on the side of the first movable seat 200, and the second groove 260 is located on the moving path of the second ball 531. During the rotation of the second operating cap 530, when the second ball 531 passes through the second groove 260, two parts of the second ball 531 are embedded in the second groove 260, and the operator can feel the rotation resistance of the second operating cap 530 at this time. Therefore, the number of times the second ball 531 passes through the second groove 260 can indicate the number of circles rotated by the second operating cap 530. For each rotation of the second operating cap 530, the second movable seat 300 can rotate relative to the first movable seat 200 by a preset angle, so that the operator can more conveniently estimate the angle value currently adjusted by the second movable seat 300. In addition, a hole is provided inside the second operating cap 530, in which a spring is preset, one end of the spring is fixed inside the hole, and the other end is connected to the second ball 531, and a portion of the second ball 531 is exposed outside the second operating cap 530. Under the elastic force applied by the spring, a portion of the second ball 531 can be embedded in the second groove 260 and withdrawn from the second groove 260 under the drive of external force.

[0069] In addition, the first adjusting nut 420 can shift the first movable seat 200 along the second direction and the opposite direction of the second direction, so that the first movable seat 200 swings back and forth around the first direction, and the second adjusting nut 520 can shift the second movable seat 300 along the first direction and the opposite direction of the first direction, so that the second movable seat 300 swings back and forth around the second direction. The first adjusting nut 420 and the first movable seat 200 are provided with abutting structures that abut against each other along the second direction and the opposite direction of the second direction, and the second adjusting nut 520 and the second movable seat 300 are provided with abutting structures that abut against each other along the first direction and the opposite direction of the first direction. Exemplarily, the first movable seat 200 has a first limiting column 270, and the first adjusting nut 420 has a first limiting portion 421, which is wrapped around the outer circumference of the first limiting column 270. Regardless of whether the first adjusting nut 420 moves along the second direction or the opposite direction of the second direction, the first limiting portion 421 can abut against the first limiting column 270 and move the first limiting column 270 along the corresponding direction to make the first movable seat 200 swing around the first direction; similarly, the second movable seat 300 has a second limiting column 320, and the second adjusting nut 520 has a second limiting portion 521, which is wrapped around the outer circumference of the second limiting column 320. Regardless of whether the second adjusting nut 520 moves along the first direction or the opposite direction of the first direction, the second limiting portion 521 can abut against the second limiting column 320 and move the second limiting column 320 along the corresponding direction to make the second movable seat 300 swing around the second direction.

[0070] Or, in another embodiment, referring to Figure 4 and Figure 5 The first movable seat 200 has a first limiting column 270, and the first adjusting nut 420 has two spaced first limiting portions 421. The two first limiting portions 421 are respectively located on both sides of the first limiting column 270 in the second direction, and respectively abut against the first limiting column 270 in the second direction and in the opposite direction of the second direction. Therefore, no matter the first adjusting nut 420 moves in the second direction or in the opposite direction of the second direction, the first limiting column 270 can be moved by the first limiting portion 421 to make the first movable seat 200 swing around the first direction. Similarly, referring to Figure 6 and Figure 7 The second movable seat 300 has a second limiting column 320, and the second adjusting nut 520 has two spaced second limiting portions 521. The two second limiting portions 521 are respectively located on both sides of the second limiting column 320 in the first direction, and are respectively abutted against the second limiting column 320 along the first direction and in the opposite direction of the first direction. Therefore, no matter whether the second adjusting nut 520 moves along the first direction or in the opposite direction of the first direction, the second limiting column 320 can be moved by the second limiting portion 521 to make the second movable seat 300 swing around the second direction.

[0071] Further, the first limiting portion 421 is configured as a protruding structure on the surface of the first adjusting nut 420, and the second limiting portion 521 is configured as a protruding structure on the surface of the second adjusting nut 520. Figure 4 The first movable seat 200 has a first receiving groove 280 that is recessed away from the adjustment base 100, the first limiting column 270 is disposed in the first receiving groove 280, the first limiting portion 421 is inserted into the first receiving groove 280, and abuts against the first limiting column 270, such as Figure 6 The second movable seat 300 has a second accommodating groove 330 that is recessed away from the first movable seat 200, and the second limiting column 320 is arranged in the second accommodating groove 330. The second limiting portion 521 is inserted into the second accommodating groove 330 and abuts against the second limiting column 320; accommodating the limiting column in the accommodating groove can make the connection between the adjustment base 100 and the first movable seat 200 and between the first movable seat 200 and the second movable seat 300 more compact, which is conducive to the miniaturization design of the angle adjustment device. In addition, the groove wall of the accommodating groove can limit the limiting portion to avoid the limiting portion from detaching from the accommodating groove due to excessive rotation angle of the first movable seat 200 or the second movable seat 300.

[0072] In addition, the first limiting column 270 and the second limiting column 320 are both arranged in a cylindrical shape. When the first movable seat 200 and the second movable seat 300 are adjusted in angle, the first limiting portion 421 can rotate around the first limiting column 270 and always abut against the first limiting column 270, so that the first movable seat 200 can swing more smoothly along the first mating surface 110. Similarly, the second limiting portion 521 can rotate around the second limiting column 320 and always abut against the second limiting column 320, so that the second movable seat 300 can swing more smoothly along the third mating surface 220.

[0073] In the present utility model, reference Figures 1 to 3 The angle adjustment device also includes a locking seat 600 and a locking assembly 700. The locking seat 600 is located on the side of the second movable seat 300 facing away from the first movable seat 200. The second movable seat 300 has a first adjustment surface 340. The first adjustment surface 340 and the fourth matching surface 310 are respectively located on the opposite sides of the second movable seat 300. The locking seat 600 has a second adjustment surface 610. Since the second adjustment surface 610 is a spherical crown surface, when the second movable seat 300 rotates to different angles in different directions, the first adjustment surface 340 and the second adjustment surface 610 can always remain in contact with each other. The locking assembly 700 includes a locking shaft 710 and a locking rod 720. The locking rod 720 is arranged along the third direction and penetrates the adjustment base 100, the first movable seat 200 and the second movable seat 300. One end of the locking rod 720 is connected to the locking seat 600, and the locking shaft 710 is connected to the other end of the locking rod 720. The first direction, the second direction and the third direction are perpendicular to each other. The locking shaft 710 can drive the locking rod 720 to reciprocate along the third direction. It can be understood that the adjusting base 100, the first movable seat 200, the second movable seat 300 and the locking seat 600 are arranged in sequence along the third direction. When the locking shaft 710 drives the locking rod 720 to move along the third direction, the locking seat 600 has a tendency to move away from the second movable seat 300. At this time, the first movable seat 200 and the adjusting base 100 and the second movable seat 300 and the first movable seat 200 can move relative to each other. By adjusting the first adjusting component 400 and the second adjusting component 500, the angle of the second movable seat 300 in the first direction and the second direction can be changed; when the locking shaft 710 drives the locking rod 720 to move in the reverse direction of the third direction, the locking seat 600 has a tendency to approach the second movable seat 300. At this time, the locking seat 600 presses against the second movable seat 300, and at the same time, the second movable seat 300 presses against the first movable seat 200, and the first movable seat presses against the adjusting base 100, and the position of the second movable seat 300 is locked.

[0074] It is understandable that a spherical groove is provided on the side of the locking seat 600 facing away from the second movable seat 300, and the locking seat 600 is accommodated in the spherical groove, so that the connection between the locking seat 600 and the second movable seat 300 is more compact. The locking seat 600, the first movable seat 200 and the second movable seat 300 are provided with a through hole penetrating along the third direction, the through hole is connected to the spherical groove, and the locking rod 720 is penetrated in the through hole and connected to the locking seat 600.

[0075] Furthermore, the locking shaft 710 is passed through the adjusting base 100 along the first direction or the second direction and is rotatably connected to the adjusting base 100. The locking shaft 710 has a radially protruding or recessed connecting portion 711, that is, the connecting portion 711 is protruding or recessed along the third direction. The end of the locking rod 720 located in the adjusting base 100 is provided with a connecting hole 721, and the connecting portion 711 is accommodated in the connecting hole 721 and abuts against the hole wall of the connecting hole 721; as the locking shaft 710 rotates, the circumferentially protruding portion of the connecting portion 711 abuts against the connecting hole When the protruding portion of the connecting portion 711 abuts against one side of the connecting hole 721 in the third direction, the locking rod 720 moves toward the third direction; when the protruding portion of the connecting portion 711 abuts against one side of the connecting hole 721 in the opposite direction of the third direction, the locking rod 720 moves away from the third direction; by rotating the locking shaft 710 and making the locking shaft 710 rotate in different directions, the protruding portion of the connecting portion 711 can be abutted against different positions of the connecting hole 721, thereby driving the locking rod 720 to reciprocate along the third direction.

[0076] It is understandable that, in order to facilitate the rotation of the locking shaft 710 , a handle 730 is connected to the end of the locking shaft 710 , and the handle 730 is for the operator to hold. By turning the handle 730 , the locking shaft 710 can be turned.

[0077] In the present utility model, reference Figure 8 and Fig. 9The angle adjustment device also includes a quick-release assembly 800, which includes a first mounting member 810, a second mounting member 820, a locking screw 830 and an abutment member 840. The first mounting member 810 is connected to the second movable seat 300, and the second mounting member 820 is provided for mounting the sample chuck 900. The locking seat 600 is located between the first mounting member 810 and the second movable seat 300. The first mounting member 810 has a first mounting groove 811 and a second mounting groove 812 that are connected. The first mounting groove 811 penetrates at least one side in the second direction. The second mounting member 820 can be mounted from the first mounting member 810. 0 is inserted into the first mounting groove 811, the abutment 840 is accommodated in the second mounting groove 812 and abuts against the second mounting groove 820 in the first direction, the abutment 840 has a first abutment wall 841, and the groove wall of the second mounting groove 812 is provided with a second abutment wall 813, the first abutment wall 841 and the second abutment wall 813 are inclined relative to the first direction and the second direction and abut against each other, the locking screw 830 is penetrated into the first mounting groove 810 along the second direction, the locking screw 830 is threadedly connected to the first mounting groove 810, and one end located in the first mounting groove 810 abuts against the abutment 840.

[0078] After the second mounting member 820 is inserted into the second mounting groove 812, the locking screw 830 is screwed, and the locking screw 830 pushes the abutment member 840 to move in the second direction. Since the first abutment wall 841 abuts and tilts with the second abutment wall 813, the abutment member 840 moves synchronously in the first direction under the guidance of the second abutment wall 813, and pushes the second mounting member 820 in the first direction, so that the side wall of the second mounting member 820 in the first direction abuts against the groove wall of the first mounting groove 811. At this time, the second mounting member 820 is locked in the first mounting groove 811, and the second mounting member 820 is quickly installed to the first mounting member 810; it can be understood that by screwing the locking screw 830 in the opposite direction, the abutment member 840 removes the pushing effect on the second mounting member 820, releases the lock on the second mounting member 820, and the second mounting member 820 can be withdrawn from the first mounting groove 811, completing the quick disassembly of the second mounting member 820.

[0079] In one embodiment, the first mounting groove 811 is configured as a dovetail groove, and the groove walls on both sides of the first mounting groove 811 in the first direction can support the second mounting member 820 in the third direction. The second mounting member 820 is limited in the first direction and the third direction in the first mounting groove 811, so that the second mounting member 820 has higher assembly stability.

[0080] In the present utility model, reference Figure 8 and Fig.10The angle adjustment device also includes a sample chuck 900, which is used to clamp the tissue sample. The sample chuck 900 is installed on the second movable seat 300 and rotates synchronously with the second movable seat 300. When the first adjustment component 400 and the second adjustment component 500 are adjusted, the angle of the tissue sample can be adjusted along the first mating surface 110 and the third mating surface 220. The sample chuck 900 includes a first clamping seat 910, a second clamping seat 920, a height adjustment member 930 and a screw cap 940. The first clamping seat 910 has a clamping portion 911. The clamping portion 911 and the second clamping seat 920 are arranged vertically opposite to each other. The clamping portion 911 is located above the second clamping seat 920, and a clamping space for accommodating a tissue sample is defined therebetween. The second clamping seat 920 is vertically slidably connected to the first clamping seat 910. The height adjustment member 930 is inserted into the first clamping seat 910 and screwed to the height adjustment member 930. The lower end of the height adjustment member 930 is connected to the second clamping seat 920, and the screw cap 940 is screwed to the upper end of the height adjustment member 930.

[0081] When the screw cap 940 is screwed, the height adjustment member 930 drives the second clamping seat 920 to rise and fall, which can change the distance between the second clamping seat 920 and the clamping portion 911, realize the clamping and release of the tissue sample, and can clamp tissue samples of different types and sizes. In addition, since the lower end of the height adjustment member 930 is fixedly connected to the second clamping seat 920, there is no relative movement between the two, which can reduce the waste of the tissue sample on the second clamping seat 920. In addition, the height adjustment member 930 is located inside the first clamping seat 910, which reduces the contact between the height adjustment member 930 and the tissue sample during the lifting process, thereby reducing the residue of the tissue sample.

[0082] The utility model also provides a slicer, which includes the above-mentioned angle adjustment device and a slicer assembly, wherein the slicer assembly includes a blade. When the tissue sample loaded on the sample chuck 900 moves relative to the blade, the blade cuts the tissue sample and obtains slices of the tissue sample.

[0083] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
