[0018] In summary, due to the adoption of the above technical scheme, the beneficial effects of the present application are:

[0019] (1) In the present application, under the position limitation of the limiting strip, the connecting block is separated from the first and second connecting grooves by pulling and moving the rotating handle, and then the corresponding moving threaded rod is driven to rotate by rotating the rotating handle, so that the distance between the two moving frames can be conveniently adjusted by rotating the moving threaded rod, and the clamping plate and the block can be close to the outer surface of the forging during the movement of the moving frame driven by the guide frame, and then the number of sliding blocks is increased or decreased according to the actual structure of the forging, and then the rotating clamping bolt can move and adjust the distance between the first and second limiting blocks by rotating the adjusting clamping bolt, so that the first limiting block and the second limiting block can extrude and fit the outer surface of the guide frame, and the sliding block can be stably arranged at different positions in the guide frame, and then under the support of the sliding block, different structures of the block can be customized according to the actual use condition, and the push frame on one side of the sliding plate is moved to adjust the position, so that the push frame can extrude and support one end of the clamping plate to deflect, and then the clamping plate and the block can extrude and fit the outer surface of the forging under the support of the top rod and the top pipe, so that the device can stably clamp and fix the forging, and then the subsequent processing of the forging is facilitated, the structure needed to be replaced for clamping and fixing different forgings is reduced, the actual production cost is reduced, and the device can efficiently realize the required function.

[0020] (2) In this invention, by tightening the limiting nut on the outer surface of the top rod, the limiting nut can press the top tube against the abutment ring for position fixation. Then, by rotating the limiting nut and the sliding plate, the height of the limiting ring and the pusher can be adjusted. When the top of the sliding plate is in contact with the bottom of the limiting ring, the top of the pusher will press the bottom of the clamping plate, so that the clamping plate can be in a horizontal state. Then, by increasing or decreasing the number of sliders used, a stable support platform can be formed between the tops of the clamping plates. Then, the existing positioning structure can be easily set through the positioning hole, so that the equipment can be temporarily used as a support platform for processing different items. At the same time, by controlling the start of the rotary motor, the rotary motor, together with the rotary gear and the rotary ring, can drive the rotation. The rotating frame allows for convenient adjustment of the limiting mechanism's operating angle. Simultaneously, by controlling the start of the adjusting motor, the motor, along with the adjusting gear and two connecting gears, drives two adjusting worm gears to rotate synchronously. Under the positional constraint of the connecting block, the rotating adjusting worm gear, in conjunction with the adjusting worm wheel, drives two moving threaded rods to rotate synchronously. These moving threaded rods then move in the same direction, adjusting the position of the two moving frames. These moving frames then drive the limiting mechanism to move horizontally, allowing for convenient adjustment of the orientation of the items carried on the top of the clamping plate. This improves the equipment's usability, prevents idle equipment, avoids wasting resources, and enhances the overall effectiveness of the equipment. Attached Figure Description
