[0025] Place the parts on both sides of the central base 6, corresponding to the first fixed end 2 and the second fixed end 4 on both sides respectively. Rotate the handle on the corresponding side to drive the first limiting part 3 and the second limiting part 5 to move towards the central base 6, forming a combined force with the anti-slip pad 63 / third limiting part 65 to clamp the parts. The corresponding limiting parts installed with quick-release fasteners can be replaced as needed to adapt to the shape of non-standard or irregular parts.

[0026] The first fixed end 2 includes a first guide seat 21, on which an installation part 22 for fixed connection is provided, and a first sliding guide groove 23 is provided on the first guide seat 21. A first fixed seat 24 is fixedly connected between the first guide seats 21, and a first threaded sleeve 25 is provided on the first fixed seat 24.

[0027] Mounting component 22 achieves fixed connection of the first fixed end 2, and the first sliding guide groove 23 cooperates with the first fixed seat 24 to provide guidance and support for the first limiting part 3, ensuring the stability and accuracy of the first limiting part 3 when it moves.

[0028] The first limiting part 3 includes a first movable plate 31 and a first limiting member 35. A first screw 32 is provided on the first movable plate 31.

A first fixing member 36 is provided on the first limiting member 35 for fixedly connecting with the first movable plate 31.

[0029] By rotating the first handle 33, the first screw 32 is driven to rotate within the first threaded sleeve 25, which allows the first moving plate 31 to slide within the first sliding guide groove 23 via the first slider 34, thereby adjusting the position of the first limiting member 35 and clamping the part. The first fixing member 36 can fix the first limiting member 35 and facilitates the replacement of different limiting members according to the shape of the part. It is suitable for clamping non-standard parts with a specific processing shape at one end.

A second fixing member 56 is provided on the second limiting member 55 for fixedly connecting to the second movable plate 51.

[0033] By rotating the second handle 53, the second screw 52 is driven to rotate, causing the second moving plate 51 to slide along the second sliding guide groove 42, adjusting the position of the second limiting member 55. The second fixing member 56 can fix the second limiting member 55. Similarly, different limiting members can be replaced according to the shape of the part.

[0034] The central base 6 includes a base body 61 and a third limiting member 65. The two sides of the base body 61 are a first positioning plate 62 and a second positioning plate 64, respectively. The first positioning plate 62 corresponds to the first limiting member 65. An anti-slip pad 63 is fixedly connected to the first positioning plate 62. The second positioning plate 64 corresponds to the second limiting member 65. A third fixing member 66 for fixedly connecting to the second positioning plate 64 is provided on the third limiting member 65.

[0035] The first positioning plate 62 corresponds to the first limiting member 35. The anti-slip pad 63 can increase the friction with the part and prevent the part from sliding. The third limiting member 65 is fixedly connected to the second positioning plate 64 through the third fixing member 66. Different limiting members can be replaced according to the shape of the irregular part to be clamped at one end of the second limiting part 5 to improve the stability and accuracy of clamping.

[0036] The working principle of the corrosion-resistant lightweight alloy fastener provided by this utility model is as follows:

[0037] Place the parts on both sides of the central base 6, corresponding to the first fixed end 2 and the second fixed end 4 on both sides respectively. Rotate the handle on the corresponding side to drive the first limiting part 3 and the second limiting part 5 to move towards the central base 6, forming a combined force with the anti-slip pad 63 / third limiting part 65 to clamp the parts. The corresponding limiting parts installed with quick-release fasteners can be replaced as needed to adapt to the shape of non-standard or irregular parts.

[0038] Compared with related technologies, the corrosion-resistant and lightweight alloy fastener provided by this utility model has the following beneficial effects:

[0039] The central base 6, together with the first fixed end 2 and the second fixed end 4 on both sides, forms a stable clamping structure, which can respectively position and clamp parts of different shapes, improving clamping stability and accuracy; the quick-release fasteners 36 / 56 / 66 can quickly replace the corresponding limiters on the first limit part 3, the second limit part 5 and the central base 6 to adapt to non-standard or irregular parts.
