The inner wall of each group of fixing frames 201 is rotatably connected with a lead screw 204, and a bearing 6 is fixedly connected to the outer surface of each lead screw 204. The outer surface of each bearing 6 is fixedly connected to the front surface of the fixing frame 201. By using the bearing 6, the lead screw 204 can be fixed to avoid the problem of shaking of the lead screw 204 during rotation.

[0023] The upper surface of the bottom plate 1 is fixedly connected with a controller 203. The outer surface of the controller 203 is fixedly connected with a fixing frame 4. The bottom surface of the fixing frame 4 is fixedly connected with the upper surface of the bottom plate 1. By using the fixing frame 4, the controller 203 can be strengthened to avoid the problem of the controller 203 moving during use.

[0024] Above the bottom plate 1, there are two servo motors 202. The outer surface of each servo motor 202 is fixedly connected with a stabilizing plate 3. The bottom surface of each stabilizing plate 3 is fixedly connected with the upper surface of the bottom plate 1. By using the stabilizing plate 3, the servo motor 202 can be strengthened to avoid the problem of the servo motor 202 fluctuating during use.

[0025] The output end of each servo motor 202 is fixedly connected with one end of a lead screw 204 close to the controller 203. The outer surfaces of two slide bars 205 are jointly slidably connected with two first clamping frames 206. The outer surfaces of two lead screws 204 are jointly threadedly connected with two second clamping frames 209. The inner walls of each second clamping frame 209 and the inner walls of the first clamping frame 206 are fixedly connected with a number of identical electric push rods 207. The upper surface of each second clamping frame 209 is fixedly connected with two telescopic rods 208. The outer surface of each telescopic rod 208 is fixedly connected with a fixing ring 7. The outer surface of each fixing ring 7 is fixedly connected with the bottom surface of the first clamping frame 206. By using the fixing ring 7, the telescopic rod 208 can be fixed to avoid the problem of the telescopic rod 208 tilting during use.

[0026] The telescopic end of each telescopic rod 208 is fixedly connected with the bottom surface of the first clamping frame 206. Above the bottom plate 1, there are two groups of fastening bolts 5. The bottom end of each group of fastening bolts 5 penetrates through the bottom plate 1 and extends to the lower side of the bottom plate 1. The outer surface of each group of fastening bolts 5 is threadedly connected with the inner wall of the bottom plate 1. By using the fastening bolts 5, the bottom plate 1 can be fixed.

[0027] The working principle of the present utility model is as follows: When in use, first connect the servo motor 202, the electric push rod 207 and the controller 203 to the power supply. When using the device to clamp the car door limiter, the staff places the car door limiter to be clamped inside the two second clamping frames 209. Then, the controller 203 is used to control the servo motor 202 to work. Driven by the support of the fixed frame 201, the servo motor 202 drives the lead screw 204 to rotate. The rotation of the lead screw 204 further drives the two second clamping frames 209 to approach each other. Then, the controller 203 is used to control the telescopic movement of the electric push rod 207 inside the second clamping frame 209 to achieve the preliminary fixation of the car door limiter. After that, according to the size of the car door limiter, the staff uses the controller 203 to control the telescopic movement of the telescopic rod 208 to adjust the distance between the first clamping frame 206 and the telescopic rod 208, and adjusts the distance between the first clamping frame 206 and the telescopic rod 208 to a suitable position. Then, the controller 203 is used to control the telescopic movement of the electric push rod 207 on the inner wall of the first clamping frame 206 to achieve the fixed clamping of the car door limiter, thereby realizing the fixation of the car door limiter. Through this device, car door limiters of different volume types can be quickly fixed, further improving the scope of use and working efficiency of the device.
