[0023] During the installation of the hydraulic oil cylinder 7, the hydraulic oil cylinder 7 needs to be vertically placed on the upper end of the fixed seat 5. In order to ensure that the cylinder can be positioned stably and accurately, the next operation is to rotate the double-headed screw rod 104 arranged at the rear end of the matching plate 102. The double-headed screw rod 104 is engraved with threads with opposite rotation directions at both ends. When the rotation operation is performed, the connecting block 103 on the surface of the screw rod will move in opposite directions along the guide rod 105 arranged inside the connecting block 103 under the action of the threads matched with each other. This process drives the clamping plate 201 in the fixed plate 204 to gradually approach the surface of the hydraulic oil cylinder 7. By observing the contact between the clamping plate 201 and the hydraulic oil cylinder 7, the position of the hydraulic oil cylinder 7 can be adjusted to ensure that it is in the best position below the installation point. After the position adjustment is completed, the double-headed screw rod 104 is continued to be rotated to make the matching plate 102 further push the fixed plate 204 to move. In this process, since the clamping plate 201 is provided with the spring 203 and the telescopic rod 202 at the rear part, the telescopic rod 202 will be squeezed while the fixed plate 204 advances, causing the telescopic rod 202 and the spring 203 to start to compress. As the pressure increases to the maximum compression distance, the rebound force generated by the spring 203 and the telescopic rod 202 will increase the pressure of the clamping plate 201 on the hydraulic oil cylinder 7, thereby ensuring that the cylinder is firmly fixed. After the above steps are completed, the external hydraulic pump is connected and started. The hydraulic pump drives the hydraulic rod 6 to rise, thereby pushing the support plate 101 and the hydraulic oil cylinder 7 on it to move upward together until the predetermined installation height is reached, thereby achieving effective auxiliary positioning of the installation position of the hydraulic oil cylinder 7.

[0024] The specific model specifications of the hydraulic pump, the hydraulic rod 6, the hydraulic oil pump, the double-headed screw rod 104, the telescopic rod 202, and the spring 203 in the present application need to be selected and determined according to the actual specifications of the device.
