[0036] The specific implementation manner of the structure for fixing screws and the method for installing screws provided by the present invention is described in detail below with reference to the accompanying drawings.

[0037] This specific embodiment provides a structure for fixing screws. Figure 1 is a schematic cross-sectional view of a structure for fixing a screw in a specific embodiment of the present invention, Figure 2 is a top view schematic diagram of a structure for fixing screws in a specific embodiment of the present invention, Figure 3 Schematic diagram of a specific embodiment of the present invention in which the tightening tool and the screw to be installed are both sleeved in the structure for fixing the screw. Figure 1 , Figure 2 and Figure 3 As shown, the structure for fixing the screw comprises:

[0038] A first elastic sleeve 11, wherein the inner diameter of the first elastic sleeve 11 is smaller than the diameter of the screw head 301 of the screw to be installed;

[0039] a second elastic sleeve 12, wherein the second elastic sleeve 12 is capable of fixing a tightening tool for tightening the screw to be installed;

[0040] A rigid connecting sleeve 13 , one end of which is fixedly connected to the first elastic sleeve 11 , and the other end of which is fixedly connected to the second elastic sleeve 12 ; the rigid connecting sleeve 13 is in communication with both the first elastic sleeve 11 and the second elastic sleeve 12 .

[0041] For example, the first elastic sleeve 11, the second elastic sleeve 12 and the rigid connection sleeve 13 all extend along the second direction D2, and the opposite ends of the rigid connection sleeve 13 along the second direction D2 are respectively connected and communicated with the first elastic sleeve 11 and the second elastic sleeve 12. The first elastic sleeve 11 is made of elastic material, so that the inner diameter of the first elastic sleeve 11 can at least expand along the first direction D1, and the first direction D1 intersects the second direction D2 perpendicularly. The screw to be installed includes the screw head 301 and the screw rod 302 connected to the screw head 301, the diameter of the screw head 301 is larger than the diameter of the screw rod 302, and the first elastic sleeve 11, the second elastic sleeve 12 and the rigid connection sleeve 13 are all hollow sleeve structures. The inner diameter of the first elastic sleeve 11 is smaller than the diameter of the screw head 301 of the screw to be installed, and the screw head 301 of the screw to be installed can extend into the first elastic sleeve 11 from the side of the first elastic sleeve 11 away from the second elastic sleeve 12, and the screw to be installed is stably fixed in the first elastic sleeve 11 by the elastic restoring force of the first elastic sleeve 11. In an example, the inner diameter of the first elastic sleeve 11 is smaller than the diameter of the screw rod 302 of the screw to be installed. When installing the screw to be installed, a tightening tool for tightening the screw to be installed into a screw hole is inserted into the second elastic sleeve 12 through the side of the second elastic sleeve 12 away from the first elastic sleeve 11, and contacts the screw head 301 of the screw to be installed in the first elastic sleeve 11 through the rigid connection sleeve 13, and the tightening tool realizes the tightening of the screw to be installed by driving the screw head 301 to rotate.

[0042] In this specific embodiment, the screw to be installed is fixed in the first elastic sleeve 11 by the first elastic sleeve 11 that can shrink freely, and the tightening tool used to tighten the screw to be installed is fixed by the elastic shrinkage of the second elastic sleeve 12, so that the screw to be installed is connected to the tightening tool, thereby avoiding the problem that a single screw is easy to fall off during the installation process. In addition, since the relative position between the screw to be installed and the tightening tool is fixed by the first elastic sleeve 11, the second elastic sleeve 12 and the rigid connection sleeve 13, the labor cost in the process of screw installation and tightening is reduced, and the efficiency of screw installation is improved, which helps to improve the efficiency and yield of semiconductor production.

[0043] In some embodiments, the inner diameter of the first elastic sleeve 11 is larger than the inner diameter of the second elastic sleeve 12, and the inner diameter of the rigid connecting sleeve 13 is larger than the inner diameter of the second elastic sleeve 12, so that not only the second elastic sleeve 12 can stably fix the tightening tool, but also the tightening tool can smoothly pass through the elastic connecting sleeve 13 and enter the first elastic sleeve 11 to contact the screw head 301 of the screw to be installed which is sleeved in the first elastic sleeve 11.

[0044] In some embodiments, the first elastic sleeve 11 comprises:

[0045] A first sleeve body 111 connected to the rigid connection sleeve 13;

[0046] A first channel 112, located in the first sleeve body 111 and connected to the rigid connection sleeve 13;

[0047] The groove 113 is located in the first sleeve body 111 . The groove 113 is located at the end of the first channel 112 facing the rigid connection sleeve 13 , and the inner diameter of the groove 113 is greater than the inner diameter of the first channel 112 .

[0048] Specifically, the first sleeve body 111 is made of elastic material, so that the first channel 112 and the groove 113 can both shrink along the first direction. The groove 113 is connected to the end of the first channel 112 along the second direction D2, and the inner diameter of the groove 113 is larger than the inner diameter of the first channel 112, so that the screw head 301 of the screw to be installed contacts the tightening tool in the groove 113, and space is reserved for the rotation of the screw head 301 and the rotation of the tightening tool, so that the screw to be installed can be smoothly fixed in a screw hole. In one example, the inner diameter of the groove 113 is larger than the inner diameter of the rigid connection sleeve 13.

[0049] In one example, the second elastic sleeve 12 includes a second sleeve body 121 and a second channel 122 penetrating the second sleeve body 121, the rigid connection sleeve 13 includes a third sleeve body 131 and a third channel 132 penetrating the third sleeve body 131, and the first channel 112, the second channel 122 and the third channel 132 are all straight channels. The inner diameter of the second channel 122 is smaller than the inner diameter of the tightening tool, so as to fix the tightening tool by elastic restoring force. The inner diameter of the third channel 132 is larger than the inner diameter of the second channel 122, so as to facilitate the smooth passage of the tightening tool.

[0050] In some embodiments, the inner diameter of the first elastic sleeve 11 is 1 mm to 20 mm to meet the installation requirements of screws of various sizes, thereby further expanding the application field of the structure for fixing screws.

[0051] In some embodiments, the material of the first elastic sleeve 11 and the material of the second elastic sleeve 12 are both elastic rubber, and the material of the rigid connection sleeve 13 is metal or hard rubber. In one example, the material of the first elastic sleeve 11 and the material of the second elastic sleeve 12 are both fluororubber or silicone rubber, and the material of the rigid connection sleeve 13 is PEEK (poly (ether-ether-ketone)) or PP (Polypropylene).

[0052] In some embodiments, the outer diameter of the first elastic sleeve 11 is greater than the outer diameter of the second elastic sleeve 12, and the outer diameter of the second elastic sleeve 12 is less than or equal to the outer diameter of the rigid connecting sleeve 13, so as to intuitively and quickly distinguish the first elastic sleeve 11 and the second elastic sleeve 12.
