[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown, an automobile fastener clamping tool comprises a base 1 and a mounting plate 3 located above the base 1 for placing fasteners, the upper surface of the mounting plate 3 is provided with a clamping device for clamping and fixing the fasteners, the base 1 and the mounting plate 3 are connected by an adjustable steering device for adjusting the angle of the mounting plate 3, and the upper surface of the base 1 is provided with a driving device for driving the adjusting device to operate.

[0028] like Figure 3-5 As shown, the driving device includes a first motor 203 and a worm 204. The first motor 203 is arranged on the upper surface of the base 1. The output end of the first motor 203 is connected to the worm 204. When the first motor 203 is started, the worm 204 is driven to rotate. The rotation of the worm 204 is connected to multiple sets of brackets, and the brackets are connected to the upper surface of the base 1 to improve the stability of the worm 204.

[0029] like Figure 2-6 As shown, the steering device includes a steering shaft 2, a rotating block 201, a slide groove 202, a half worm gear 205 and a slide bar 206. The rotating block 201 is provided with two groups and the slide groove 202 is provided on the surface. The slide bar 206 is provided on the upper surface of the base 1. The rotating block 201 is slidably connected with the slide bar 206 through the slide groove 202. The length of the slide bar 206 is less than the length of the slide groove 202. The rotating block 201 slides along the path of the slide bar 206. The steering shaft 2 is fixedly connected between the two groups of rotating blocks 201. The steering shaft 2 is fixedly connected with the half worm gear 205. The surface of the half worm gear 205 is sprayed with a galvanized layer to extend its service life. The half worm gear 205 is meshed with the worm 204. When the worm 204 rotates, it drives the half worm gear 205 to rotate. The upper end of the steering shaft 2 is connected with a mounting plate 3.

[0030] like Figure 1 and Figure 7As shown, the clamping device includes a fixed clamping plate 4, a second motor 401, a screw 402, a movable clamping plate 403 and a guide rod 404. The fixed clamping plate 4 is fixedly connected to the mounting plate 3.

Mobile clamping plates 403 are arranged on both sides of the fixed clamping plate 4 and the mobile clamping plates 403 are rotatably connected to the screw 402. When the second motor 401 is started, the movable clamping plate 403 can be driven by the screw 402 to approach or move away from the fixed clamping plate 4 to complete the clamping or loosening work. The inner walls of the fixed clamping plate 4 and the movable clamping plate 403 are provided with anti-slip pads to make the clamping of the fastener more stable. The end of the movable clamping plate 403 away from the screw 402 is slidably connected to the guide rod 404.
