[0021] The present invention will be described in further detail below in conjunction with specific embodiments and accompanying drawings.

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the slide replacement mechanism in the pollen collector comprises: a chassis 1 of the pollen collector, a drawer box 6 is detachably inserted on the chassis 1, a slide table 7 is arranged in the drawer box 6, a slide 4 is detachably fixed on the slide table 7, the slide 4 that needs to be replaced can be removed from the chassis 1 by pulling the drawer box 6 out of the chassis 1, and the replaced slide 4 can be installed in the chassis 1 by inserting the drawer box 6 back into the chassis 1;

[0023] like Figure 6 , Figure 7 As shown, a slide slot 8 for accommodating a slide 4 is provided on the front end of the slide stage 7. The slide 4 can be inserted into the slide slot 8 from front to back. A pair of enclosures 9 are provided on the front end of the slide slot 8 to prevent the inserted slide 4 from sliding outward and escaping from the slide slot 8. The inner ends of the two enclosures 9 are respectively hinged to the two sides of the front end of the slide slot 8. The two enclosures 9 can rotate around their respective hinge points, so that the outer ends of the two enclosures 9 can be closed or opened with each other. When the two enclosures 9 are closed, the slide 4 can be stably closed in the slide slot 8. When the two enclosures 9 are opened, the slide 4 can be easily inserted or removed. The above structure can make it very convenient to install the slide 4 on the slide stage 7.

[0024] In this embodiment, a hook 10 is respectively provided on the outer end of the two enclosures 9, and the outer ends of the two enclosures 9 can be connected by hooking each other through the two hooks 10. The two enclosures 9 can be reliably and stably kept in a closed state by overlapping each other; of course, in actual manufacturing, torsion springs and other means can be used at the hinges to make the two enclosures 9 reliably closed.

[0025] In this embodiment, a paddle 11 is provided on the outer ends of the two enclosures 9 respectively, and the two hooks 10 can be disengaged by external force acting on the two paddles 11. Such a structure can make the operation more convenient and quick.

[0026] In this embodiment, the front end of the drawer box 6 is open, so that the two enclosures 9 can extend out of the front end of the drawer box 6 without being restricted by the drawer box 6, thereby facilitating the opening or closing of the two enclosures 9; the use of the above structure can conveniently reduce the size of the drawer box 6.

[0027] In this embodiment, if Figure 3 , Figure 7 As shown, a long through hole 28 is provided at the bottom of the drawer box 6, and a limit screw 27 is threadedly connected to the bottom of the glass carrier 7. The limit screw 27 is penetrated by the long through hole 28. The length of the long through hole 28 can ensure the normal sliding of the glass carrier 7, but it will not separate from the drawer box 6. The limit screw 27 and the long through hole 28 can prevent the glass carrier 7 and the drawer box 6 from separating.

[0028] like Figure 6 , Figure 7 As shown, a positioning groove 24 is provided on the inner surface of the side wall of one side of the drawer box 6, and an elastic protrusion 26 is provided on one side of the glass stage 7. The elastic protrusion 26 is inserted into the positioning groove 24, so that the glass stage 7 can be positioned in the drawer box 6. This arrangement can prevent the glass stage 7 from sliding freely in the drawer box 6.

[0029] Before replacing the glass slide 4, the glass stage 7 needs to be moved forward so that the enclosure 9 extends out of the front end of the drawer box 6, and then the operator manually acts on the two paddles 11 to disengage the two hooks 10, then opens the two enclosures 9, takes out the old glass slide 4 and inserts the new glass slide 4 into the glass slide slot 8, then closes the two enclosures 9, and pushes the glass stage 7 back into the drawer box 6 until the elastic protrusion 26 is snapped into the positioning groove 24.

[0030] like Figure 2 , Figure 4 , Figure 5 As shown, a guide plate 29 is provided in the chassis 1, a track groove 30 is provided on the guide plate 29, and a guide edge 31 is provided on one side of the drawer box 6. When the drawer box 6 is inserted into the chassis 1, the guide edge 31 can be inserted into the track groove 30. The insertion of the drawer box 6 can be guided and limited by the cooperation of the track groove 30 and the guide edge 31, so that the drawer box 6 can be smoothly inserted back into the chassis 1.

[0031] A ball plunger 32 with a ball head exposed in the track groove 30 is fixed on the guide plate 29, and a positioning pit 33 is provided on the side of the guide edge 31. After the drawer box 6 is inserted into the chassis 1, the ball head on the ball plunger 32 will be exactly inserted into the positioning pit 33, so that the drawer box 6 can be positioned. This arrangement can effectively prevent the drawer box 6 from sliding outwards by itself and separating from the chassis 1.

[0032] A sealing ring is provided on the side wall of the drawer tail plate 35 of the drawer box 6, and a drawer handle 36 is provided on the outer end surface of the drawer tail plate 35. The drawer box 6 can be plugged in and out through the drawer handle 36. When the drawer box 6 is inserted in place on the chassis 1, the drawer tail plate 35 will abut against the chassis 1 to limit the position, and the sealing ring on the drawer tail plate 35 will abut against the inner wall of the drawer hole 34 on the chassis 1 to seal the drawer hole 34. This arrangement can effectively improve the waterproof performance of the pollen collector.
