[0010] A supporting mechanism, which is arranged at the bottom of the base plate and is used to adjust and support the base plate;

[0011] The adjusting mechanism is arranged on the bottom plate and is used for adjusting and assembling inner chain plates of different sizes.

[0012] In a possible design, the adjustment mechanism includes a motor fixedly mounted on the top of the base plate, the output end of the motor is fixedly connected to a bidirectional screw via a coupling, the end of the bidirectional screw away from the motor is rotatably connected to one side of one of the vertical plates via a rotating shaft, the outer wall of the bidirectional screw is threadedly connected to two symmetrical moving blocks, and limit blocks are fixedly arranged at the bottom of the two moving blocks, and a limit groove is provided on the top of the base plate for the limit block to be slidably connected.

[0020] In the utility model, the large-pitch chain assembly tool described can achieve the rotation of the base by rotating the handle through the supporting mechanism, and the base drives the threaded rod to rotate inside the internal threaded tube. The threaded connection between the threaded rod and the internal threaded tube can make the base move downward and be placed directly on the ground, thereby supporting the device. Since the four bases are respectively arranged at the four corners of the bottom of the base plate, the height can be adjusted according to the actual situation of the ground, which is conducive to improving the stability of the placement of the device. At the same time, the rubber pad at the bottom of the base is combined with the ground to play an anti-slip effect and improve the stability of the placement. If necessary, the mounting bolts can be used to penetrate the mounting holes and fixed to the ground, which can further play a reinforcing role and enhance the firmness effect.
