[0027] The outer surface of the fixed pipe 1 is fixedly connected with a mounting plate 13, and mounting holes 14 arranged in a circumferential array are formed on the outer surface of the mounting plate 13. Through the mounting plate 13 and the mounting holes 14, the fixed pipe 1 can be installed on the hydraulic press. The size of the mounting plate 13 is not limited and can be adjusted according to the size of the hydraulic press, which can increase the practicability of the device.

[0028] Through the mounting holes 14, the connection between the fixed pipe 1 and the hydraulic press can be made more stable, and at the same time, the sealing performance between the fixed pipe 1 and the hydraulic press can be better, effectively increasing the safety of the device.

[0029] The inner wall of the mounting hole 14 is threadedly connected with a bolt 15. The right end of the bolt 15 is fixedly connected with a nut 16, and a gasket 17 is sleeved on the outer surface of the bolt 15. The bolt 15 can be used to fix the mounting plate 13, and the nut 16 can make it more convenient for the staff to rotate the bolt 15.

[0030] The mounting plate 13 can be protected by the gasket 17, and the outer surface of the nut 16 is passivated, which can effectively prevent the staff from being scratched and can increase the safety and practicability of the device.

[0031] A protective sleeve 3 is arranged outside the fixed pipe 1, and a connecting sleeve 4 is fixedly connected to the inner wall of the protective sleeve 3. The inner wall of the connecting sleeve 4 is fixedly connected to the outer surface of the fixed pipe 1.

[0032] See Figures 1-3 , the connecting sleeve 4 can be protected by the protective sleeve 3. Through the connecting sleeve 4, it is more convenient to connect the fixed pipe 1 to the connecting pipe 2. At the same time, it has good sealing performance, avoiding liquid leakage, and can increase the safety of the device.

[0033] Four threaded rods 10 are arranged outside the protective sleeve 3. One end of the threaded rod 10 penetrates through the protective sleeve 3 and is rotatably connected to a clamping plate 11. By rotating the threaded rod 10, the clamping plate 11 can be driven to move, and thus the purpose of clamping the fixed pipe 1 and the connecting pipe 2 can be achieved, which can increase the stability of the connecting pipe 2.

[0034] Anti-slip lines are provided on the inner wall of the clamping plate 11 to prevent the connecting pipe 2 from sliding off, effectively increasing the safety and practicality of the device.

[0035] A turntable 12 is fixedly connected to the outer surface of the threaded rod 10. The outer surface of the turntable 12 is passivated. Through the turntable 12, it is more convenient and easier for the staff to rotate the threaded rod 10, and the operation of the staff can be made simpler.

[0036] A protective pad can be sleeved on the outer surface of the turntable 12, which can increase the comfort of the staff and at the same time protect the staff's palm, increasing the safety of the device.

[0037] An installation mechanism 5 is arranged outside the fixed pipe 1. The installation mechanism 5 includes a sliding sleeve 501 that slides on the outer surface of the protective sleeve 3. Equally spaced moving columns 502 are fixedly connected to the inner wall of the sliding sleeve 501. The other end of the moving column 502 is fixedly connected to a baffle 503. A number of limiting balls 504 for limiting the connecting pipe 2 are arranged inside the connecting sleeve 4.

[0038] See Figures 3-4 , the connecting pipe 2 can be fixed and limited by the limiting balls 504. The limiting balls 504 can be fixed by the sliding sleeve 501, the moving columns 502 and the baffle 503, avoiding the disconnection of the connecting pipe 2 caused by the shaking of the limiting balls 504 during the operation of the device, which can effectively increase the safety of the device. The inner wall of the sliding sleeve 501 is polished, which can reduce the wear caused by the sliding of the sliding sleeve 501 and at the same time make the sliding of the sliding sleeve 501 smoother, effectively reducing the operation difficulty of the device.

[0039] A first telescopic spring 505 for driving the moving column 502 to automatically reset is fixedly connected to the outer surface of the moving column 502.

A plug rod 507 for limiting the sliding sleeve 501 is slidably connected to the inner wall of the fixing frame 506. The plug rod 507 is inserted into the sliding sleeve 501 and the protective sleeve 3.

[0043] See Figures 1-3 , the fixing frame 506 and the plug rod 507 can limit the sliding sleeve 501 to prevent the sliding sleeve 501 from sliding during the use of the device, effectively increasing the safety of the device. The plug rod 507 can slide in the fixing frame 506. The outer surface of the plug rod 507 is polished to reduce the wear caused by the sliding of the plug rod 507, effectively increasing the service life of the device.

[0044] The other end of the plug rod 507 is fixedly connected to a moving disk 508. A second telescopic spring 509 for driving the moving disk 508 to automatically reset is fixedly connected to the outer surface of the moving disk 508. The other end of the second telescopic spring 509 is fixedly connected to the outer surface of the fixing frame 506.

[0045] See Figures 1-3 , the movement of the moving disk 508 can drive the plug rod 507 to move, and at the same time can drive the second telescopic spring 509 to deform. The elastic force generated when the second telescopic spring 509 deforms can drive the moving disk 508 to automatically reset, effectively reducing the operation difficulty of the device. A protective pad can be sleeved on the outer surface of the moving disk 508 to protect the palm of the staff and increase the safety of the device at the same time.

[0046] Two connecting plates 7 for synchronously moving the moving plate 508 are arranged outside the fixed pipe 1. The two ends of the connecting plate 7 are respectively fixedly connected to the outer surfaces of the two moving plates 508. The connecting plate 7 can be used to connect the two moving plates 508, ensuring that the moving plates 508 move synchronously and reducing the operation difficulty of the device.

[0047] The connecting plate 7 is made of a waterproof and rust-proof material, which can avoid device failures caused by bending and breaking of the connecting plate 7 and effectively increase the safety of the device.

[0048] A pull rod 8 is fixedly connected to the outer surface of the connecting plate 7, and the other end of the pull rod 8 is fixedly connected to a pull plate 9. The pull rod 8 and the pull plate 9 can make it more convenient for the staff to pull the connecting plate 7, effectively reducing the operation difficulty of the device and thus increasing the practicality of the device.

[0049] The outer surface of the pull plate 9 is passivated to protect the palm of the staff. A protective pad can be sleeved on the outer surface of the pull plate 9 to increase the comfort of the staff.

[0050] The specific implementation process of the present utility model is as follows: When using the device, first pull the pull plate 9. The pull plate 9 can drive the pull rod 8 to move, and then drive the moving plate 508 to move through the connecting plate 7. The movement of the moving plate 508 can drive the insertion rod 507 to move, thereby releasing the limit on the sliding sleeve 501 and driving the second telescopic spring 509 to deform at the same time. Then pull the sliding sleeve 501. The movement of the sliding sleeve 501 can drive the moving column 502 and the baffle 503 to move, driving the first telescopic spring 505 to deform at the same time and releasing the limit on the limit ball 504. Then insert the connecting pipe 2 into the inner part of the protective sleeve 3, so that the limit ball 504 is stuck into the inner part of the connecting pipe 2. Then release the sliding sleeve 501. Then, the elastic force generated when the fixed frame 506 deforms can drive the moving column 502 to automatically reset, and then drive the sliding sleeve 501 to reset. Then, the elastic force generated when the second telescopic spring 509 deforms can drive the insertion rod 507 to insert into the inner parts of the protective sleeve 3 and the connecting sleeve 4, thus achieving the purpose of installing the connecting pipe 2.

[0051] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
