[0016] 1. The utility model is equipped with an adjustment mechanism to adjust the driving distance of the hydraulic cylinder, facilitating the fixation of workpieces at different positions. The driving distance of the existing hydraulic cylinder is fixed, resulting in the situation that when the workpiece is at a relatively far distance, the hydraulic cylinder cannot fix the workpiece even when it reaches its limit. Therefore, improvements are needed. First, according to the distance of the workpiece, take out the storage top cover from the top of the storage box, then select the corresponding extension plate, fix the extension plate to the splicing screw groove through the splicing screw, and then take out a protective soft board from the fitting groove and adsorb it on the first magic tape to install the protective soft board.

[0017] 2. The utility model is equipped with a filtering mechanism to facilitate the filtration of the oil entering the hydraulic cylinder and avoid the accumulation of impurities inside the hydraulic cylinder. The inlet pipe is used for oil inlet, and there may be impurities in the transported oil, leading to the accumulation of impurities in the hydraulic cylinder. Therefore, improvements are needed. First, fix the filter screen to the fixed screw hole through the fixed screw and install it in the filter frame, then use the filter screen to filter impurities. At the same time, the fluctuating rod works to drive the fluctuating block to be removed from the slot hole, and the movement of the fluctuating block stirs the oil to avoid stratification. Then, the solenoid valve works to transport the oil to the inlet pipe, thus avoiding the situation where impurities are adsorbed in the hydraulic cylinder and making it difficult to clean the hydraulic cylinder.

Then, the hydraulic cylinder 3 works to drive the extension plate 9 to move, and the extension plate 9 fixes the position of the workpiece, avoiding the situation where the workpiece cannot be fixed due to the distance or size of the workpiece being too small.

[0031] Please refer to Figure 3 and Figure 7, a filtering mechanism is provided on the outer wall of the oil inlet pipe 4. The filtering mechanism is used to facilitate the filtering of the oil body entering the hydraulic cylinder 3, avoiding the accumulation of impurities inside the hydraulic cylinder 3.

In the case where there may be impurities in the transported oil, which may lead to the accumulation of impurities in the hydraulic cylinder 3, so it is necessary to make improvements. First, the filter net 19 is fixed to the fixing screw hole 20 through the fixing screw rod 21 and installed in the filtering frame 16. Then, the filter net 19 is used to filter impurities. At the same time, the fluctuating electric rod 23 works to drive the fluctuating block 24 to be removed from the slot hole 25, and the movement of the fluctuating block 24 is used to stir the oil to avoid stratification. Subsequently, the electromagnetic valve 18 works to transport the oil into the oil inlet pipe 4, thus avoiding the situation that impurities are adsorbed in the hydraulic cylinder 3 and making it difficult to clean the hydraulic cylinder 3.

[0032] Working principle: The inlet pipe 4 is connected to the external pipeline. The tailstock body 1 is installed on the equipment by using the bolt groove 2. Subsequently, the hydraulic cylinder 3 works, and the output rod of the hydraulic cylinder 3 fixes the workpiece. The driving distance of the existing hydraulic cylinder 3 is fixed. When the workpiece is at a relatively long distance, the hydraulic cylinder 3 still cannot fix the workpiece even when it works to the limit. Therefore, it is necessary to improve this situation. First, according to the distance of the workpiece, the storage top cover 6 is taken out from the top of the storage box 5. Subsequently, the corresponding extension plate 9 is selected, and the extension plate 9 is fixed to the splicing screw groove 10 through the splicing screw 11. Then, a protective soft plate 14 is taken out from the fitting groove 13 and adsorbed on the first magic tape 12 through the second magic tape 15 to install the protective soft plate 14. Then, the hydraulic cylinder 3 works to drive the extension plate 9 to move, and the extension plate 9 fixes the position of the workpiece, avoiding the situation that the workpiece cannot be fixed due to the large or small distance. The inlet pipe 4 is used for oil inlet. There may be impurities in the transported oil, resulting in the accumulation of impurities in the hydraulic cylinder 3. Therefore, it is necessary to improve this situation. First, the filter screen 19 is fixed to the fixed screw hole 20 through the fixed screw 21 and installed in the filter frame 16. Then, the filter screen 19 filters the impurities. At the same time, the fluctuating electric rod 23 works to drive the fluctuating block 24 to be removed from the slot hole 25, and the movement of the fluctuating block 24 stirs the oil to avoid stratification. Subsequently, the solenoid valve 18 works to transport the oil to the inlet pipe 4, avoiding the situation that the impurities are adsorbed in the hydraulic cylinder 3, making it difficult to clean the hydraulic cylinder 3.
