[0034] The utility model will be further described in detail below in combination with the drawings.

[0035] Embodiment 1, a cylinder body structure of an oil cylinder, refer to Figure 1 , comprising cylinder body 1, the piston rod can be installed in cylinder body 1, this is prior art;

[0036] Cylinder body 1 is equipped with two connecting pipes 11, and the connecting pipe 11 is used to oil inlet and oil outlet; The connecting pipe 11 is provided with external thread, is used to the external oil pipe.

[0037] Refer to Figures 5-6 Connecting pipe 11 outer wall is fixed with the limiting pull ring 2 and is separated from the clamping piece 12 of connecting ring, and the clamping piece 12 is hexagon nut, and the clamping piece 12 is welded and fixed on the outer wall of connecting pipe 11;

[0038] Connecting pipe 11 is equipped with pull ring 2, and pull ring 2 is circular, and pull ring 2 is located between cylinder body 1 and clamping piece 12, and pull ring 2 is difficult to separate from connecting pipe 11 by the blocking effect of clamping piece 12;

[0039] Pull ring 2 is fixed with pull rope 3, and pull rope 3 is steel wire rope.

[0040] Refer to Figure 1 And Figure 2 One end of pull rope 3 is fixed with collar 4; Collar 4 includes upper ring 41 and lower ring 42, and upper ring 41 and lower ring 42 are both metal rings; The size of upper ring 41 and lower ring 42 is same, and the axis of the two rings is in the same straight line;

[0041] Upper ring 41 is located above lower ring 42, and there is a gap between upper ring 41 and lower ring 42, and the gap forms side hole 51;

[0042] Refer to Figures 2-4 Lower ring 42 and lower ring 42 are fixed with shaft 43, and shaft 43 has two, and two shafts 43 are located at the two ends of the diameter of collar 4.

[0043] The rotating shaft 43 is hingedly connected with a baffle 52, one end of the baffle 52 is sleeved on the rotating shaft 43, the rotating shaft 43 is sleeved with an elastic element 53, the elastic element 53 is a torsion spring, one end of the torsion spring is fixed on the sleeve ring 4, and the other end of the torsion spring is fixed on the baffle 52.

[0044] The baffle 52 is a semicircular sheet, there are two baffles 52, under the driving of the torsion spring, the baffle 52 slides from the side hole 51 into the sleeve ring 4, and the diameter edges of the two baffles 52 are attached to each other, so that the closing of the ring opening of the sleeve ring 4 can be realized.

[0045] When the ring opening of the sleeve ring 4 needs to be opened, the user pinches the baffle 52 of the sleeve ring 4 with fingers to rotate it out of the side hole 51, so that the sleeve ring 4 can be opened.

[0046] The clamping and restraining structure of the oil pipe on the cylinder body 1 is referred to Figure 1 、 Figures 5-6 ;

[0047] The upper ring 41 is sleeved and slides on the cap part 82 of the hose 81;

[0048] The user rotates the baffle 52 to open the sleeve ring 4, then the user inserts the cap part 82 of the hose 81 into the sleeve ring 4, and then releases the baffle 52 so that the baffle 52 is clamped on the pipe wall of the hose 81, at this time, the baffle 52 blocks the cap part 82 of the hose 81, so that the hose 81 is difficult to separate from the restraint of the sleeve ring 4;
