[0016] The utility model has the following beneficial effects:

[0017] 1. The universal wheel is set to facilitate the movement of the driving device. When it moves to the specified position, the electric push rod is started, so that the electric push rod drives the friction plate to move down until the friction plate contacts the ground. At this time, the stability of the load-bearing platform is improved. When the height of the load-bearing platform needs to be adjusted, the fixing pin is rotated to disengage the threaded groove. At this time, the connecting rod can be rotated 90°, so that the fixing pin is opposite to the opening of another threaded groove. Then the fixing pin is connected to the threaded groove to fix the connecting rod. By repeating the above operations, the connecting rod is vertical to the supporting legs, which makes it convenient to adjust the height of the load-bearing platform.

[0018] Second, by placing the vacuum furnace on the top of the supporting platform and then starting the servo motor, the servo motor drives the bidirectional lead screw to rotate, thereby driving the two movable seats to move toward each other, and then driving the two clamping plates close to the base until the base and the rubber column are abutted, so that the rubber column is retracted into the inside of the spring groove and compresses the connecting spring. When the end face of the rubber column abuts against the control switch, the control switch will turn off the servo motor. At this time, the two clamping plates will abut against the opposite sides of the base, thereby improving the stability of the vacuum furnace. Compared with direct lifting operations, it is safer and more reliable. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The bottom of the support leg 401 is plugged into the top of the connecting rod 402, and the relative outer side walls of the support leg 401 are fixedly connected with a rotating shaft, which extends through the outer surface of the connecting rod 402, wherein the connecting rod 402 can move in an arc with the central axis of the rotating shaft as the origin.

[0031] The moving assembly also includes a rotating disk 406 fixedly connected to the end face of the rotating shaft, and a fixing pin 407 threadedly connected to the rotating disk 406, wherein there are two rotating disks 406, which are respectively located on opposite side walls of the supporting leg 401, wherein the length of the fixing pin 407 is greater than the top width of the connecting rod 402.

[0032] The moving component also includes a thread groove 408 opened on the outer surface of the connecting rod 402. There are several thread grooves 408, which are distributed in a circular array with the midpoint of the rotation axis as the origin, wherein the longitudinal section of the thread groove 408 matches the longitudinal section of the fixing pin 407.

[0033] The moving assembly also includes a mounting cover fixedly connected to the bottom of the support platform 3 , an electric push rod 404 fixedly connected to the outer side wall of the mounting cover, and a friction plate 405 fixedly connected to the output end of the electric push rod 404 .

[0034] The universal wheel 403 is provided to facilitate the movement of the driving device. When it moves to the specified position, the electric push rod 404 is started, so that the electric push rod 404 drives the friction plate 405 to move downward until the friction plate 405 contacts the ground. At this time, the stability of the load-bearing platform 3 is improved. When it is necessary to adjust the height of the load-bearing platform 3, the fixing pin 407 is rotated so that the fixing pin 407 is disengaged from the thread groove 408.
