Detailed Embodiments

[0018] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model more clear and understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0019] It should be noted that when a component is referred to as "fixed to" or "disposed on" another component, it can be directly on the other component or indirectly on the other component. When a component is referred to as "connected to" another component, it can be directly or indirectly connected to the other component.

[0020] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.

[0021] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0022] The present invention provides a tool for expanding and riveting a quick-release screw lock, as Figures 1-3 shown, including: a workbench 1, on which a positioning hole 2 is provided. A positioning sleeve 3 is installed in the positioning hole 2. A support screw 4 is arranged in the positioning sleeve 3. A support table 5 is arranged above the workbench 1. The support table 5 is connected to the workbench 1 through a support arm 6. A moving rod 7 passes through the support table 5 and is slidably connected to the support table 5. A punch 8 is arranged below the moving rod 7, and the punch 8 is located above the positioning sleeve 3.

[0023] The working principle and beneficial technical effects of the above technical solution: Place the mounting plate 19 and the support 20 on the workbench 1, align the mounting hole with the positioning sleeve 3, place the quick-release screw lock 21 on the mounting hole, and the punch 8 presses downward, so that the quick-release screw lock 21 expands and rivets to close the mouth, riveting the mounting plate 19 and the support 20, improving the expanding and riveting efficiency, and preventing the screw lock from loosening or the riveting from being incomplete.

[0024] In one embodiment, a groove 9 is provided at the top end of the support table 5, a round hole 10 is provided at the bottom wall of the groove 9, the moving rod 7 passes through the round hole 10, a pressing plate 11 is arranged at the upper end of the moving rod 7, a spring 12 is sleeved on the moving rod 7, one end of the spring 12 is connected to the pressing plate 11, and the other end of the spring 12 is connected to the bottom wall of the round hole 10.
