[0023] like Figure 1-4 As shown, the utility model provides an angle-adjustable slice spreading brush, comprising: a handle 100, a rod body 200 and an angle adjustment mechanism 300; wherein, bristles 210 are provided at the end of the rod body 200; the angle adjustment mechanism 300 is directly connected to the handle 100 and the rod body 200, so that the angle of the rod body 200 can be adjusted relative to the handle 100.

[0024] Compared with the prior art, the angle-adjustable slicing and spreading brush provided by the present invention enables the rod body 200 to be adjusted relative to the handle 100 through the angle adjustment mechanism 300, thereby enabling the brush head to be angle-adjusted, making slicing experiments more convenient; and reducing the burden on the hand muscles of the experimenter during long-term experiments, thereby improving the slicing success rate, reducing the waste of experimental samples, and improving experimental efficiency.

[0025] In one embodiment, the angle adjustment mechanism 300 includes a first connecting plate 310, a second connecting plate 320 stacked with the first connecting plate 310, a stud 370 fixed to the first connecting plate 310, and a fastening knob 330 screwed to the stud 370. The stud 370 passes through the second connecting plate 320, the first connecting plate 310 is fixedly connected to the rod body 200, and the second connecting plate 320 is fixedly connected to the handle 100. It is understood that the first connecting plate 310 and the stud 370 are welded or integrally formed, and the second connecting plate 320 has a through hole for passing the stud 370. By loosening the fastening knob 330, the second connecting plate 320 can rotate around the stud 370, thereby adjusting the angle between the connecting rod and the handle 100 to which the first connecting plate 310 and the second connecting plate 320 are respectively fixed, so that the brush head can be adjusted to a desired angle and then fixed by the fastening knob 330. The handle 100 and the rod body 200 can be arranged in the same straight line direction by connecting plate 1 310 and connecting plate 2 320 , so that the center of the handheld handle 100 and the center of the brush head are always on the same plane, which is conducive to precise operation.

[0026] Furthermore, in order to reduce the probability of the angle adjustment mechanism 300 colliding with an instrument or other objects, the edges of the connecting plate 1 310 and the connecting plate 2 320 are designed to be arc edges.

[0027] In one embodiment, the angle adjustment mechanism 300 further includes an angle disc 340 fixedly connected to the side of the second connecting plate 320 and a pointer 350 fixed to the stud 370. With this arrangement, the handle 100 is used as a reference, the second connecting plate 320 and the angle disc 340 are relatively stationary, and when the rod body 200 is rotated, the stud 370 rotates synchronously with the pointer 350 and indicates the angle corresponding to the angle disc 340, thereby accurately adjusting the angle of the brush head relative to the handle 100. This facilitates more precise and labor-saving operation. It should be noted that when the handle 100 and the brush head are in the same straight line, the pointer 350 indicates zero degrees on the angle disc 340.

[0028] In one embodiment, the angle adjustment mechanism 300 further includes a damping pad 360 disposed between the pointer 350 and the tightening knob 330. The damping pad 360 is sleeved around the outer circumference of the stud 370. It is understood that the damping pad 360 is compressed by the tightening knob 330 and elastically deforms. During operation, when the tightening knob 330 is slightly loosened, there is a certain resistance when the adjustment rod 200 is rotated. When the pointer 350 stops at the specified angle, even if the rod 200 is released, the pointer 350 will not rotate, thereby making it easier to tighten the tightening knob 330.

[0029] In one embodiment, the microtome spreading brush includes two symmetrically arranged angle adjustment mechanisms 300. One end of each of the two connecting plates 310 is fixedly connected to the rod body 200, and one end of each of the two connecting plates 320 is fixedly connected to the handle 100. This increases the connection strength between the handle 100 and the rod body 200, and prevents the handle 100 and the rod body 200 from deviating from each other and affecting the accuracy of the brush head.

[0030] In one embodiment, the distance between the two angle adjustment mechanisms 300 is 3-10 mm, which is suitable for the width or diameter of most handles 100 and rod bodies 200. The angle adjustment mechanism 300 will not be too prominent, which would affect the convenience of operation.

[0031] In one embodiment, the handle 100 and / or the rod body 200 is a telescopic rod, so as to improve the adaptability of the microtome spreading brush.

[0032] In one embodiment, the handle 100 is in the shape of a long rectangular rod with rounded corners. Compared with a cylindrical structure, the handle 100 in the shape of a long rectangular rod with rounded corners is not easy to rotate and has higher hand-holding stability.

[0033] In one embodiment, anti-slip strips 110 are provided at the four rounded corners of the handle 100. The anti-slip strips 110 are thin rubber strips or thin latex strips, which are used to further improve the hand-holding stability.

[0034] In one embodiment, the rod body 200 is cylindrical in shape. Of course, the shape of the rod body 200 can also be the same as that of the handle 100.

In line with the present application, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of different aspects of one or more embodiments of the present application as described above, which are not provided in detail for the sake of simplicity.
