[0064] In this embodiment, the positions of the longitudinal septum 7 and the transverse septum 20 can be adjusted according to the size of the cup (box) shaped specimen. Specifically, first, the transverse insertion section 25 of the transverse septum 20 is inserted from the bottom end of the longitudinal septum 8 into the transverse insertion groove 24 to form a snap-fit ​​relationship. Then, a suitable longitudinal insertion groove 22 on the support plate 7 is selected, and the aforementioned longitudinal insertion section 23 on the longitudinal septum 7 is inserted to form a snap-fit ​​relationship. Figures 13-15 As shown, this can form a relatively stable connection structure.

[0065] The longitudinal partition 8 has horizontal insertion slots 24 at both ends, which makes it easier for operators to select the appropriate direction to place the horizontal partition 20.

[0066] Preferably, the specimen rack 15 includes two symmetrically arranged connecting plates 151, and three insertion plates 152, positioning plates 153 and placement plates 154 arranged from top to bottom are connected between the two connecting plates 151. The insertion plates 152 are provided with a plurality of insertion through holes 155, and the positioning plates 153 are provided with a plurality of positioning through holes 156 corresponding to the plurality of insertion through holes 155 respectively.

[0067] The bottom end of the connecting plate 151 is provided with the groove structure 16.

[0068] Preferably, the placement plate 154 has a plurality of limiting through holes 157 corresponding to a plurality of positioning through holes 156, and the diameter of the limiting through holes 157 is smaller than the diameter of the positioning through holes 156.

[0069] In this embodiment, the tubular specimen or long specimen collector can be positioned and stored by the placement plate 152, positioning plate 153, and placement plate 154. The limiting through hole 157 can position the bottom of the tubular specimen or long specimen collector.

[0070] To facilitate the movement of the specimen rack 15, preferably, the top of the connecting plate 151 is provided with a handle opening 158.

[0071] Preferably, a protective frame 9 is installed around the placement platform 1 on the vehicle body 1. In this embodiment, the protective frame 9 prevents specimens from accidentally detaching from the placement platform 11 during operation. The protective frame 9 can surround three sides of the vehicle body 1 or be inclined outwards.

[0072] Preferably, the bottom end of the vehicle body 1 is provided with a movable wheel 2;

[0073] A parking mechanism 5 is fixedly installed on the side wall of the vehicle body 1;

[0074] The parking mechanism 5 includes a fixing plate 54 connected to the side wall of the vehicle body 1 and an "L"-shaped fixing shell 51;

[0075] A telescopic sleeve 52 is slidably disposed between the fixed plate 54 and the fixed shell 51. A brake block 512 is connected to the bottom end of the telescopic sleeve 52, and a number of brake teeth 58 are provided on the side end of the telescopic sleeve 52.

An iron block 515 is provided on the locking rod 59. A magnetic block 510 that can be magnetically attracted to the iron block 515 is provided on the fixed shell 51.

[0077] The parking mechanism 5 also includes an upper elastic element 517 located between the top of the fixed plate 54 and the telescopic sleeve 52.

[0078] In this embodiment, the movable wheels 2 facilitate the movement of the vehicle body 1; the parking mechanism 5 enables the vehicle body 1 to be parked.

[0079] When parking vehicle 1 is required, first rotate the locking lever 59 to disengage the locking tooth 514 from the brake tooth 58. Then, overcome the upper elastic element 517 to lower the telescopic sleeve 52, allowing the brake block 512 to contact the ground. Next, rotate the locking lever 59 in the opposite direction to re-engage the locking tooth 514 with the brake tooth 58. The magnetic attraction between the magnetic block 510 and the iron block 515 achieves the effect of locking the height. The fixed shell 51 and the fixed plate 54 are used to limit the up and down movement of the telescopic sleeve 52, preventing it from deviating unexpectedly.

[0080] When parking body 1 is not required, rotating the locking lever 59 causes the locking tooth 514 to engage with the corresponding braking tooth 58. Then, through the magnetic attraction between the magnetic block 510 and the iron block 515, the telescopic sleeve 52 can be prevented from moving down unexpectedly.

[0081] Preferably, the top end of the telescopic sleeve 52 is connected to a crossbar 53, a connecting rod 55 is connected to the crossbar 53, and a downward handle 56 is provided on the connecting rod 55;

[0083] The locking lever 59 has a protruding handle 516 at its end.

[0084] In this embodiment, the downward handle 56 facilitates medical staff to manually move the telescopic sleeve 52 downward, and the protruding handle 516 facilitates medical staff to rotate the locking lever 59.

[0085] The buffer elastic element 57 can improve the stability of the telescopic sleeve 52 during reset.

[0086] Preferably, an anti-slip pad 513 is installed at the bottom end of the brake block 512, which can enhance the friction between the brake block 512 and the ground, thereby improving the braking effect.

[0087] A rotating pedal 511 is rotatably connected to the telescopic sleeve 52. The rotating pedal 511 has a rotation angle of 0°-90°. The rotating pedal 511 is designed to facilitate medical staff to move the telescopic sleeve 52 down by foot.
