[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a slide holder for immunohistochemistry.

[0025] Example 1

[0026] Reference Figure 1-3 A slide holder for immunohistochemistry includes a fixing shell 1 and a piston 3. The two fixing shells 1 are arranged abutting each other from front to back. A mounting shell 4 is fixedly installed on one side of the fixing shell 1. An air suction hole is opened in the middle of the mounting shell 4. The piston 3 is slidably installed inside the fixing shell 1. A threaded hole is opened in the middle of the side of the fixing shell 1 away from the mounting shell 4. An exhaust hole is opened on the upper side of the threaded hole, so that the piston 3 can move smoothly. A lead screw 5 is threaded inside the threaded hole. One end of the lead screw 5 is rotatably connected to the piston 3. A rotating wheel is fixedly sleeved on the outer end of the lead screw 5 to facilitate the rotation of the lead screw 5. A strip groove is opened in the middle of the rear side of the fixing shell 1. A slider 9 is slidably installed inside the strip groove. A fixing rod 10 is fixedly installed on one side of the inside of the strip groove. The slider 9 is movably sleeved with the fixing rod 10. A cavity is opened inside the fixing shell 1 and on one side of the strip groove. A sliding rod 6 is provided on the lower side of the lead screw 5. One end of the sliding rod 6 extends to the outer side of the fixing shell 1, so that the piston 3 cannot rotate, that is, it can slide stably.

[0027] Example 2

[0028] Reference Figure 1-3 The cavity is equipped with a limiting mechanism to restrict the movement of the slider 9. The limiting mechanism includes a rotating rod 7 and a torsion spring 8. The rotating rod 7 is rotatably disposed inside the cavity. One end of the rotating rod 7 extends to the outside of the cavity. A baffle 2 is fixedly sleeved on the outside end of the rotating rod 7. The baffle 2 abuts against the outer wall of the fixed shell 1 on the other side.

[0029] Example 3

[0030] Reference Figure 1-3 A torsion spring 8 is movably sleeved on the rod wall of the rotating rod 7. The two ends of the torsion spring 8 are fixedly connected to the corresponding rotating rod 7 and the inner wall of the cavity, respectively. In the natural state, the elastic force of the torsion spring 8 will cause the rotating rod 7 to drive the baffle 2 to rotate to the horizontal.

[0031] In this invention, during use, rotating the lead screw 5 causes the piston 3 to move, thus allowing air to be drawn in through the suction hole. This enables stable adsorption of the slides, achieving rapid and efficient positioning of the slides. The slider 9 is then inserted into the groove and slid, causing it to fit onto the fixed rod 10. In its natural state, the spring force of the torsion spring 8 drives the rotating rod 7 to rotate, causing the baffle 2 to rotate and block the outside of the fixed shell 1 on the other side. This prevents the two fixed shells 1 from moving horizontally relative to each other, extending the device and facilitating adjustment of the slide holder size according to the actual number of slides.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
