However, since a large number of test tubes need to be cleaned each time, using a single test tube brush each time is too time-consuming and laborious, affecting the cleaning efficiency. On the other hand, if multiple test tube brushes are used simultaneously by hand, it is difficult to hold them or the grip is unstable, resulting in poor cleaning effect.

[0003] Therefore, designing a brush assembly that can integrate a large number of brushes is a problem that needs to be solved by those working in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a brush for cleaning glass test tubes. By designing a novel brush device, a large number of brushes can be installed on the same tray, thereby cleaning a large number of test tubes simultaneously and improving cleaning efficiency. At the same time, the connecting parts are used to connect the test tube brushes to the mounting tray, which facilitates the installation, disassembly, and position adjustment of the test tube brushes, making it easy to replace new brushes or brushes of different specifications and styles, which is convenient for operators and improves the applicability.

[0007] The mounting plate has several mounting grooves evenly spaced in a ring on its periphery, and several mounting openings that are respectively opposite to the mounting grooves on the mounting plate. A handle is fixed at the top center of the mounting plate.

[0008] The connector includes an inner fastener and an outer fastener;

[0009] Both ends of the inner fastener are provided with inner end plates. The gap between the inner fasteners is set at the inner end of the mounting groove. The two inner end plates are in contact with the top and bottom surfaces of the mounting plate, respectively. The two inner end plates and the mounting opening are fixed by bolts. Each inner end plate is provided with a set of clips.

[0010] Both ends of the outer fastener are provided with outer end plates. The outer fastener is slidably disposed in the mounting groove. The two outer end plates slide along the top and bottom surfaces of the mounting plate, respectively. A set of retaining edges is provided on the inner side of the outer end plates. The outer fastener is fixed to the inner fastener by retaining the retaining edges and retaining heads.

[0011] Both the outer side of the inner fastener and the inner side of the outer fastener are provided with a semi-circular locking groove, and a soft pad is fixed to the inner wall of the locking groove.

[0012] Several test tube brushes are fixed in several mounting slots by several connectors, and the brush rod section of the test tube brush is locked between the soft pads of the inner fastener and the outer fastener.

[0013] Furthermore, the clamp head is a trapezoidal block, the inclined surface of the clamp head faces the outward fastener, and the two clamp heads are respectively located on both sides of the clamp rod groove.

[0014] Furthermore, the retaining edge is an elastic edge, and a trapezoidal block is provided on the bottom surface of the retaining edge end, with the inclined surface of the trapezoidal block facing the inner fastener.

[0015] Furthermore, the brush rod section of the test tube brush is a twisted wire brush rod structure, and the soft pad is wrapped around the outer wall of the brush rod of the test tube brush.

[0016] Furthermore, the mounting groove is a straight groove structure, and the top, bottom and outer sides of the mounting groove are all open sides.

[0017] Furthermore, the mounting plate is a stainless steel plate or a wooden plate.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, through the design of a novel brush-dispensing device, enables the installation of a large number of brushes on the same tray, thereby simultaneously cleaning a large number of test tubes and improving cleaning efficiency.
