[0004] A screw-locking mechanism includes a base plate. The base plate is provided with a product positioning bracket, a horizontal cylinder bracket, an upper and lower cylinder bracket, a horizontal cylinder control valve, an upper and lower cylinder control valve, and a linear guide. A product positioning fixture is provided on the top of the product positioning bracket. A horizontal cylinder is provided on the top of the horizontal cylinder bracket, and a fixing block is provided at the output end of the horizontal cylinder. The horizontal cylinder control valve is electrically connected to the horizontal cylinder. Upper and lower cylinders are provided on the upper and lower cylinder brackets, and positioning blocks are provided at the output ends of the upper and lower cylinders. The upper and lower cylinder control valves are electrically connected to the upper and lower cylinders. An L-shaped electric screwdriver fixing plate is slidably provided on the linear guide, and an electric screwdriver is horizontally mounted on the L-shaped electric screwdriver fixing plate. The electric screwdriver, the positioning block, and the fixing block cooperate with each other.

[0005] Furthermore, a front baffle and a rear baffle are respectively provided at both ends of the linear guide. Furthermore, a magnet is provided at the bottom of the L-shaped electric screwdriver fixing plate, and a magnetic adsorption piece is provided on the rear baffle.

[0006] Furthermore, handles are provided at both ends of the base plate.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: the utility model has a simple structure and can stably fix the product; when the electric screwdriver rotates forward, it can press the product spring into the product screw slot; when the electric screwdriver rotates in reverse, it can control the positioning position of the slider in the product; it can greatly reduce the intensity of manual operation, improve operational safety and quality, and improve production efficiency.

Detailed Implementation

[0011] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0012] Please refer to the instruction manual appendix. Figure 1 As shown, this utility model is a screw-locking mechanism, including a base plate 1. The base plate 1 is provided with a product positioning bracket 2, a horizontal cylinder bracket 4, an upper and lower cylinder bracket 7, a horizontal cylinder control valve 15, an upper and lower cylinder control valve 16, and a linear guide 12. The top of the product positioning bracket 2 is provided with a product positioning fixture 3. The top of the horizontal cylinder bracket 4 is provided with a horizontal cylinder 5, and the output end of the horizontal cylinder 5 is provided with a fixing block 6. The horizontal cylinder control valve 15 is electrically connected to the horizontal cylinder 5. The upper and lower cylinder bracket 7 is provided with upper and lower cylinders 8, and the output end of the upper and lower cylinders 8 is provided with a positioning block 9. The upper and lower cylinder control valve 16 is electrically connected to the upper and lower cylinders 8. An L-shaped electric screwdriver fixing plate 13 is slidably provided on the linear guide 12, and an electric screwdriver 14 is horizontally provided on the L-shaped electric screwdriver fixing plate 13. The electric screwdriver 14 cooperates with the positioning block 9 and the fixing block 6.

[0013] As a preferred, but not limited, feature, the linear guide 12 is provided with a front baffle 10 and a rear baffle 11 at its two ends. As a preferred, but not limited, feature, the bottom of the L-shaped electric screwdriver fixing plate 13 is provided with a magnet 17, and the rear baffle 11 is provided with a magnetic adsorption piece, which can prevent the electric screwdriver 14 from interfering with product installation when it is not in use.
