[0026] Referring to Figures 3-4 As shown, the control box 2 is provided with a push rod 6 matched with the positioning member on one side, and the machine body 1 is provided with a groove 101 matched with the push rod 6 on the side where the push rod 6 is installed, the groove 101 formed in the machine body 1 does not affect the strength of the machine body 1 as a whole and the supportability of the workbench 4, and at the same time, the groove 101 can accommodate the push rod 6 and a fixing rod 7.

[0027] The push rod 6 is provided with a first connecting rod 603, the first connecting rod 603 penetrates through the push rod 6, and the first connecting rod 603 is fixedly connected in the groove 101 on both sides. The fixing rod 7 is provided with a second connecting rod 701, the second connecting rod 701 penetrates through the fixing rod 7, and the second connecting rod 701 is fixedly connected in the groove 101 on both sides. The fixed point of the second connecting rod 701 in the groove 101 is slightly higher than the fixed point of the first connecting rod 603 in the groove 101, the push rod 6 rotates around the first connecting rod 603, the fixing rod 7 rotates around the second connecting rod 701, and the rotation of the push rod 6 and the fixing rod 7 is matched.

[0028] Referring to Figures 3-4As shown, the push rod 6 is provided with a bayonet 604, and a plurality of pushers 601 are installed in the bayonet 604. The space of the bayonet 604 is sufficient to accommodate the plurality of pushers 601. The push rod 6 is provided with a connecting hole 602 matched with the pushers 601. The angle of the plurality of pushers 601 can be adjusted according to the size of the materials on site to adapt to materials of different sizes. The pushers 601 can be fixed by installing a bolt assembly. The bolt assembly penetrates the connecting hole 602, and the angle of the plurality of pushers 601 can be manually adjusted by tightening or loosening the bolt assembly.

[0029] The fixed rod 7 is installed around the push rod 6. The fixed rod 7 is sleeved on the outer side of the push rod 6 and forces the push rod 6 to rotate and displace by the abutting assembly arranged in the fixed rod 7. The length of the fixed rod 7 is sufficient to accommodate the push rod 6, and the push rod 6 will not bump into the fixed rod 7 during rotational movement. The fixed rod 7 is internally provided with an abutting assembly matched with the push rod 6. The abutting assembly is used to force the push rod 6 in the fixed rod 7 to rotate and displace around the first connecting rod 603.

[0030] Reference Figures 3-4 As shown, the abutting assembly includes a third connecting rod 801 and a spherical head 802. The surface of the third connecting rod 801 is provided with a thread. A nut matched with the thread is sleeved on the third connecting rod 801. The fixed rod 7 is provided with a threaded hole 702 matched with the third connecting rod 801. The third connecting rod 801 penetrates the threaded hole 702. The nut on the third connecting rod 801 is located on the outer side of the fixed rod 7, and is used to fix the third connecting rod 801 which is rotated into the fixed rod 7 through the thread.

[0031] The end of the third connecting rod 801 away from the push rod 6 is connected with a handle 8. The handle 8 is connected with the third connecting rod 801 through a thread. At this time, the fixed rod 7 and the handle 8 are connected to form a whole. The handle 8 is located on the outer side of the fixed rod 7. The third connecting rod 801 and the spherical head 802 are located on the inner side of the fixed rod 7. The handle 8, the third connecting rod 801, the spherical head 802 and the fixed rod 7 move together. Holding the handle 8 can control the fixed rod 7 to rotate around the second connecting rod 701, and force the push rod 6 to rotate synchronously through the third connecting rod 801 and the spherical head 802 in the fixed rod 7.

[0032] Reference Figures 3-4 As shown, the side of the push rod 6 close to the spherical head 802 is provided with a sliding surface 605 matched with the spherical head 802. When the sliding surface 605 and the spherical head 802 are in the abutting state, the fixed rod 7 can drive the push rod 6 to rotate. When the spherical head 802 is located in the groove close to the first connecting rod 603 on the sliding surface 605, the push rod 6 is located away from the material. At this time, the push rod 6 is locked and limited by the fixed rod 7, and cannot continue to rotate downward and remains fixed.

[0033] Reference Figures 1-2As shown, the handheld handle 8 is pushed upward, the abutting assembly in the fixed rod 7 abuts the push rod 6, forces the push rod 6 to rotate counterclockwise around the first connecting rod 603, and drives the pusher 601 installed on the push rod 6 during the rotation of the push rod 6, so that the pusher 601 approaches the cylindrical material. At this time, continue to rotate the handle 8 upward, when the push rod 6 rotates to a certain angle, the spherical head 802 in the fixed rod 7 abutting the sliding surface 605 is separated from the groove close to the lower side on the sliding surface 605 and enters the upper side of the sliding surface 605. At this time, the end of the push rod 6 close to the cylindrical material approaches parallel to the machine body 1, and the pusher 601 installed on the push rod 6 approaches or has contacted the cylindrical material.

[0034] The handheld handle 8 continues to rotate upward, and the abutting assembly in the fixed rod 7 further compresses the rotation of the push rod 6. At this time, the pusher 601 installed on the push rod 6 pushes the cylindrical material to the direction of the positioning baffle 5 during the rotation of the push rod 6, and finally pushes the cylindrical material to the center of the positioning baffle 5 to complete the positioning of the cylindrical material.

[0035] Push the handle 8 downward, and the abutting assembly in the fixed rod 7 re-abuts the push rod 6 after moving a distance, forces it to rotate clockwise around the first connecting rod 603 and finally returns to the initial position, and is locked and positioned by the abutting assembly.

[0036] In specific use, after the material is placed on the surface of the workbench 4 close to the positioning baffle 5, without adjusting the specific position, the handheld handle 8 is rotated upward, at this time, the handle 8 drives the fixed rod 7 fixedly connected thereto, and the abutting assembly in the fixed rod 7 forces the push rod 6 to rotate with the fixed rod 7, and the push rod 6 rotates around the first connecting rod 603. During the process, the pusher 601 installed on the push rod 6 approaches the cylindrical material and finally pushes the cylindrical material to the direction of the positioning baffle 5. Finally, the pusher 601 pushes the positioning baffle 5 to the predetermined position and is in the same central axis position as the hydraulic column 3 above, completing the rapid positioning of the cylindrical material.

[0037] At this time, the hydraulic column 3 is controlled to be pressed downward and the pressing process is completed. During this process, the handle 8 can be used to continuously position the material according to the site situation, or the handle 8 can be pushed downward to drive the push rod 6 to complete the reset and wait for the next material to be placed on the workbench 4 and repeat the operation.

[0038] Compared with the prior art, the simple single-column hydraulic machine can conveniently position the cylindrical material, the push rod can be used for rapid displacement and positioning of the material without manual carrying, the processing precision is increased, and the work efficiency is improved.
