[0027] In order to make the above-mentioned purpose, features and advantages of the present application more apparent and easy to understand, the specific embodiments of the present application will be described in detail below with reference to the drawings of the specification.

[0028] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from the description, and those skilled in the art can make similar generalizations without departing from the concept of the present application, therefore the present application is not limited by the specific embodiments disclosed below.

[0029] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. In this specification, "in one embodiment" does not mean the same embodiment, nor does it mean an embodiment that is separate or selectively excluded from other embodiments.

[0030] Embodiment 1

[0031] Reference Figure 1For the first embodiment of the utility model, the embodiment provides a four-foot glass slide tooth forceps, including elastic unit 100, including first forceps handle 101 and second forceps handle 102, and the inner side surface between first forceps handle 101 and second forceps handle 102 forms the clamping gap.

[0032] Clamping unit 200, including first forceps leg 201 and second forceps leg 202 fixedly arranged at the bottom of first forceps handle 101 and second forceps handle 102.

[0033] It should be noted that the top of first forceps handle 101 and second forceps handle 102 is fixedly connected, the inner side surface between the two forms a clamping gap, and the bottom of first forceps handle 101 and second forceps handle 102 is fixedly connected with first forceps leg 201 and second forceps leg 202, first forceps leg 201 and second forceps leg 202 are in the expanded state, and the clamping angle is formed between the two forceps legs. The whole forceps is a four-foot forceps.

[0034] When using, the four-foot forceps is moved parallel or vertically to the outside of the slide, and the whole forceps is slightly lifted, the forceps teeth are moved to the slide, and the two forceps handles are pressed to realize fixation by forming four clamping support points on the slide through the four forceps legs.

[0035] In summary, by changing a single forceps leg into two forceps legs, the problem that the two-foot glass slide tooth forceps cannot clamp articles such as circular glass slides and rectangular glass slides can be solved. When double-point clamping, the stress points are two points. When the clamping force is too small, the glass slide will turn over, affecting the operation. When the clamping point is too large, the glass slide may be broken. Through four-point clamping, the turning problem of the glass slide clamped by the two-foot glass slide tooth forceps can be effectively prevented.
