Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model It clearly and completely retouches, it is clear that the embodiment retouched is only the utility model a part of the embodiment, instead of all the embodiments. Based on the embodiments of the present invention, what those of ordinary skill in the art obtained without making creative work has Other embodiments are fallen within the protection scope of the utility model.
Fig. 1-4 is please referred to, the utility model provides a kind of technical solution:
A kind of high school student's test tube brush for chemical experiment, including thin cylinder 1, rubber block 2 and thin bar 3, the lower end of thin cylinder 1 is fixed to be connected It is connected to fixed plate 16, rubber block 2 is fixedly connected on the lower end of fixed plate 16, and successively activity runs through thin cylinder 1 and fixed plate 16 to thin bar 3 And reach in rubber block 2, thin bar 3 is located at one end that one section of lateral wall in rubber block 2 is symmetrically connected with two springs 4, spring 4 Other end activity through fixed plate 16 and connecting rod 5 is connected with, one end of connecting rod 5 is fixedly connected with the first magnet 6, thin cylinder 1 one section of lateral wall fixing sleeve for being located at 16 top of fixed plate is connected to the second magnet 7, and the first magnet 6 and the second magnet 7 to connect Bar 5 is fixed stronger, and the other end of connecting rod 5 is fixedly connected on the lateral wall of brush holder support 8, and the lower end of brush holder support 8 is hinged on The upper end of fixed plate 16 is fixedly connected with bristle 10 on the lateral wall of brush holder support 8, and the upper end fixing sleeve of thin bar 3 is connected to nut 13, spiral shell Cap 13 is threaded on the lateral wall of thin 1 upper end of cylinder.
Specifically, the lower end of thin bar 3 is fixedly connected with arc block, so that thin bar 3 will not be by rubber when being used for a long time Blob of viscose 2 punctures.
Specifically, fixing sleeve is connected to disk 12 on one section of lateral wall of thin cylinder 1, the lower section of disk 12 is fixedly connected with the 4th Magnet 11, the upper end of brush holder support 8 are fixedly connected with the third magnet 9 to match with the 4th magnet 11, get back in this way in brush holder support 8 When just can be good at fixing brush holder support 8.
