[0002] In prior art, the workpiece is usually fixed on the jig by screw directly, and the screw is easy to be loose during the processing, carrying or transporting of the jig, which leads to the separation of the workpiece from the jig and causes economic loss. SUMMARY

[0003] The utility model aims at overcoming the defects of prior art and provides a prevent screw from separating from jig.

[0004] To achieve the above-mentioned purpose, the utility model adopts the technical scheme of a prevent screw from separating from jig, which comprises a fixed jig and a plurality of fixed screws, the fixed jig is used for bearing a workpiece, a plurality of the fixed screws are arranged along the periphery of the fixed jig, an elastic gasket is arranged on each fixed screw, and the plurality of fixed screws pass through the fixed jig and the workpiece from bottom to top in sequence and fix the fixed jig and the workpiece.

[0005] Preferably, the elastic gasket is made of EVA material.

[0006] Preferably, a plurality of installation grooves are formed in the peripheral wall of the fixed jig, and the plurality of installation grooves are used for accommodating the plurality of fixed screws.

[0007] Preferably, positioning bolts are arranged on both sides of the fixed jig, and the positioning bolts are used for positioning the workpiece.

[0008] Preferably, the fixed jig has a hollow structure.

[0009] Due to the use of the above technical scheme, the utility model has the following advantages compared with the prior art:

[0010] The utility model discloses a prevent screw from separating from jig, which is characterized by the following: an elastic gasket is arranged on each fixed screw, and the plurality of fixed screws pass through the fixed jig and the workpiece from bottom to top in sequence and fix the fixed jig and the workpiece. BRIEF DESCRIPTION OF DRAWINGS

[0011] The technical scheme of the utility model will be further described below with reference to the drawings:

[0012] ATTACHMENT Figure 1 The utility model discloses a prevent screw from separating from jig structure schematic view.

[0013] ATTACHMENT Figure 2The utility model discloses a structure schematic diagram of removing workpiece.

[0014] Attached Figure 3 To attach Figure 2 The enlarged view of A in the middle. Specific embodiments

[0015] The utility model makes further detailed description in combination with the drawings and specific embodiments.

[0016] As shown in attached Figures 1-3 The utility model discloses a prevent screw from separating from jig, contain fixed jig 1 and a plurality of fixed screw 2, in this embodiment, fixed jig 1 is hollow structure inside, a plurality of fixed screw 2 are set along the periphery of fixed jig 1.

[0017] Fixed jig 1 is used for bearing workpiece 3, and each fixed screw 2 is provided with elastic gasket 4, and in this embodiment, elastic gasket 4 is EVA material, and a plurality of fixed screw 2 pass through fixed jig 1 and workpiece 3 from below to above in turn, and fixed jig 1 and workpiece 3 are fixed.

[0018] By setting elastic gasket 4, the performance of elastic deformation of elastic gasket 4 is utilized, when fixed screw 2 and elastic gasket 4 cooperate, not only can workpiece 3 and fixed jig 1 be fixed tightly, but also can prevent fixed screw 2 from separating.

[0019] Among them, the outer peripheral wall of fixed jig 1 is provided with a plurality of installation grooves 5, and the plurality of installation grooves 5 are used for accommodating the plurality of fixed screws 2, and the fixed screws 2 are accommodated through the installation grooves 5, which can reduce the volume of the fixed jig 1 and save space for the fixed jig 1.

[0020] The both sides of fixed jig 1 are provided with positioning bolt 6, and the positioning bolt 6 is used for positioning workpiece 3 to ensure the rapid positioning of workpiece 3.

[0021] The above is only the specific application example of the utility model, and does not constitute any limitation on the protection scope of the utility model, and the technical solutions formed by equivalent transformation or equivalent replacement all fall within the protection scope of the utility model.
