The first positioning part protrudes from the second positioning part toward the first part to be positioned. The first positioning part abuts against the corner of the first part to be positioned, and the second positioning part abuts against the corner of the second part to be positioned.

3. The positioning fixture of claim 2, wherein The first positioning part has two opposing first positioning edges, which are arranged in a V-shape and can fit into the adjacent side of the first part to be positioned. And / or, the second positioning part has two opposing second positioning edges, which are arranged in a V-shape and can fit into the adjacent side of the second part to be positioned.

4. The positioning fixture of claim 2, wherein The dimension of the first positioning part along the thickness direction is greater than or equal to the dimension of the first part to be positioned along the thickness direction; And / or, the dimension of the second positioning part along the thickness direction is greater than or equal to the dimension of the second part to be positioned along the thickness direction.

5. The positioning fixture according to any one of claims 2 to 4, wherein The positioning block can move relative to the support base plate along the diagonal direction of the first part to be positioned, so that the two positioning components move closer to or further away from each other along the diagonal direction of the first part to be positioned.

6. The positioning fixture of claim 5, wherein The positioning component further includes a first guide portion and a second guide portion. The first guide portion is disposed on the positioning block, and the second guide portion is disposed on the support base plate and cooperates with the first guide portion to guide the movement of the positioning block along the diagonal direction of the first object to be positioned.

7. The positioning fixture of claim 6, wherein One of the first guide portion and the second guide portion is a guide groove, and the other is a guide rod. The guide groove extends along the diagonal direction of the first part to be positioned, and the guide rod is located in the guide groove. Alternatively, one of the first guide portion and the second guide portion may be a guide rail, and the other may be a guide slider. The guide rail extends along the diagonal direction of the first member to be positioned, and the guide slider is slidably disposed in the guide groove.

8. The positioning fixture according to any one of claims 2 to 4, wherein The positioning component further includes an elastic element that extends along the diagonal direction of the first part to be positioned and elastically connects the support base plate and the positioning block. The elastic force provided by the elastic element can push the positioning block toward the first part to be positioned so that the positioning block presses against the first part to be positioned and the second part to be positioned.

9. The positioning fixture of claim 8, wherein, The supporting base plate has a mounting groove extending along the diagonal direction of the first positioning component. Part of the positioning block is placed in the mounting groove and can move along the mounting groove. The elastic element is located in the mounting groove and elastically connects the positioning block to the inner wall of the mounting groove. And / or, the positioning block has a mounting cavity on the side facing the elastic member, and the elastic member is partially housed in the mounting cavity.

10. The positioning fixture according to any one of claims 2 to 4, wherein The positioning block further includes a first positioning body and a second positioning body, wherein the first positioning body is provided with the first positioning part and the second positioning part at one end, and the second positioning body is provided at the other end; The first positioning body is used to set the first guide part, and the second positioning body is used to connect the elastic element.
