BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a perspective view of a positioning fixture of the present invention.

Figure 2 is a partially exploded view of the positioning fixture of the present invention.

Figure 3 is an enlarged plan view of the upper cover of the positioning fixture of the present invention.

Figure 4 is an enlarged view of the upper cover of the positioning fixture of the present invention at another angle.

Please refer to FIG. 1 and FIG. 2 , which is a positioning jig 1 of the present invention, which is used for positioning a main board 2 . The positioning fixture 1 includes a substrate 10 and a support plate 11 fixedly mounted on the substrate 10. The support plate 11 is used to place the main board 2 to be positioned.

The positioning fixture 1 further includes two quick clips 12 fixed to both sides of the substrate 10 and the support board 11 and an upper cover 13 disposed on the main board 2. The upper cover 13 interacts with the quick clip 12 to fix the main board 2 to the support board 11.

In order to better understand the present invention, the specific structure and motion fit relationship of each component of the present invention in a specific embodiment will be described in detail below.

Referring to FIG. 3 and FIG. 4 simultaneously, the upper surface of the support plate 11 is formed with a recessed portion 110. The main board 2 to be positioned is placed in the recess 110. The two sides of the recessed portion 110 are provided with at least two frequency pins 111 for defining the main board 2 to be positioned in the recess 110. Two supporting blocks 112 are disposed on two sides of the supporting plate 11 along the longitudinal direction thereof, and a second positioning block 113 is disposed along a side of the width direction and away from the upper cover 13 . The first positioning block 112 and the first positioning block 112 Two positioning blocks 113 are used to define the upper cover 13 on the support plate 11 s position. Two third positioning blocks 114 are disposed on a side of the support plate 11 away from the second positioning block 113. The support plate 11 is provided with a notch 115 between the two third positioning blocks 114 for providing a sliding space for the upper cover 13.

The quick clip 12 is the same as the quick clip mechanism of the prior art, and includes two symmetric handles 121 and a fixing portion 122 for engaging with the two handles 121 respectively. When the user lifts the handle 121 upward, the fixing portion 122 presses down the handle 121 as the user presses the handle 121 downward as the handle 121 is lifted up.

A through hole 130 is defined in an end of the upper cover 13 away from the main board 2.

The positioning jig 1 further includes a locking mechanism 14 slidably coupled to the upper cover 13. The engaging mechanism 14 includes a sliding bar 140, a handle 141 slidably coupled to the sliding bar 140, a slider 143 fixedly disposed at the bottom of the handle 141, and an extending portion 144 fixedly coupled to the slider 143. The handle 141 passes through the through hole 130 and defines a through hole 1410. After the sliding rod 140 passes through the through hole 1410, the two sides of the sliding rod 140 are respectively supported on the upper cover 13, so that the engaging mechanism 14 is slidably coupled to the upper cover 13 . In the present embodiment, an opening 20 is provided on a side of the main board 2 adjacent to the engaging mechanism 14, and the opening 20 is matched with the size of the extending portion 144. The handle 141 slides the upper cover 13 along the third positioning block 114 on the support plate 11 under an external force until the slider 143 slides into the notch 115 on the support plate 11, and then applies an external force to the handle 141. Until the extension portion 144 is completely received into the opening 20 of the main board 2, the upper cover 13 is completely engaged with the main board 2.

When the motherboard 2 is positioned, the user first lifts the handles 121 on both sides of the quick clip 12 The fixing portion 122 on the quick clip 12 is lifted upward. Then, the user inserts the main board 2 from one side of the support board 11 until the main board 2 is blocked by the frequency pin 111 provided on the support board 11 to stop pushing in. Then, the user drives the upper cover 13 to move on the support plate 11 by pushing the handle 141 until the extension portion 144 on the engaging mechanism 14 is completely received into the opening 20 in the main plate 2. Finally, the user presses the handle 121 on both sides of the quick clip 12, so that the fixing portion 122 presses the upper surface of the upper cover 13, so that the main board 2 is fixed between the support board 11 and the upper cover 13, thereby facilitating the user. The main board 2 performs corresponding processing operations.

After the main board 2 is processed, when the main board 2 is removed, the user lifts the handles 121 on both sides of the quick clip 12, so that the fixing portion 122 on the quick clip 12 is lifted upward, thereby releasing the external force on the upper cover 13. A pulling force is then applied to the handle 141 such that the extension 144 of the upper cover 13 is removed from the opening 20 of the main plate 2, and a pulling force is applied to the handle 141 such that the upper cover 13 is finally removed from the support plate 11. Finally, the user removes the main board 2 from the support board 11.
