[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment 1

[0022] See also Figure 1 , Figure 2 A circulating hydraulic motor is shown in the figure, including a motor body 1, a mounting seat 2 which is interconnected with the motor body 1 is fixedly installed on the outer side of the motor body 1, two symmetrically distributed threaded mounting holes 6 are opened on the upper end of the mounting seat 2, and a blocking structure 3 is also included, which is used to block the threaded mounting holes 6, and the blocking structure 3 is movably embedded in the threaded mounting holes 6. The blocking structure 3 includes a connecting seat 301 installed on the upper end of the mounting seat 2; a connecting component 4, which is used to connect the mounting seat 2 and the blocking structure 3, and the connecting component 4 is installed on the outer side of the blocking structure 3; a magnetic block 5, which is used to position the blocking structure 3, and the magnetic block 5 is installed in the blocking structure 3.

[0023] See also Figure 3 A plurality of anti-skid grooves are provided on the outer side of the connecting seat 301, and the anti-skid grooves can increase the friction between the fingers and the connecting seat 301. The connecting component 4 includes an elastic ring 401 movably sleeved in the anti-skid groove of the connecting seat 301, and an elastic rope 402 is fixedly connected to the outer side of the elastic ring 401. The elastic ring 401 is made of rubber, and an embedded block 403 is fixedly connected to one end of the elastic rope 402 away from the elastic ring 401, and the embedded block 403 is fixedly embedded in the outer side of the mounting seat 2.

[0024] The working principle capable of preventing the oil plug from being lost: after the sealing structure 3 is taken out from the threaded mounting hole 6, the elastic rope 402 is hung on the outside of the mounting seat 2 through the elastic ring 401, so that the sealing structure 3 is connected to the motor body 1 through the connecting assembly 4, which can effectively prevent the sealing structure 3 from being lost after disassembly.

[0025] Embodiment 2

[0026] See also Figure 4 This embodiment further explains Example 1. A pressure rod 302 that can move up and down passes through the center of the connecting seat 301. A gasket 303 is fixedly connected to the lower end of the pressure rod 302. The gasket 303 can prevent the pressure rod 302 from detaching from the connecting seat 301. An annular airbag 304 is movably sleeved on the outer side of the pressure rod 302. The annular airbag 304 is made of rubber, and the upper and lower end surfaces of the annular airbag 304 are fixedly adhered to the connecting seat 301 and the gasket 303 respectively.

[0027] See also Figure 4 The upper end of the pressure rod 302 is fixedly connected to a pressure plate 305, and the outer side of the pressure rod 302 is located at the upper end of the connecting seat 301 and is movably sleeved with a spring 306. The spring 306 can drive the pressure rod 302 to move upward, and the two ends of the spring 306 are movably abutted against the connecting seat 301 and the pressure plate 305 respectively.

[0028] In this embodiment: when the sealing structure 3 is used to block the threaded mounting hole 6, the person clamps the connecting seat 301 with the index finger and the middle finger, and then presses the pressure plate 305 with the thumb to increase the distance between the gasket 303 and the connecting seat 301. Since the two ends of the annular airbag 304 are fixedly adhered to the connecting seat 301 and the gasket 303 respectively, the diameter of the annular airbag 304 will decrease after the distance between the gasket 303 and the connecting seat 301 increases. Then, the annular airbag 304 with a reduced diameter is inserted into the threaded mounting hole 6, and the pressure plate 305 is released. The pressure plate 305 will move upward under the drive of the spring 306, and the distance between the gasket 303 and the connecting seat 301 will decrease, so that the diameter of the annular airbag 304 will increase, and fit tightly with the inner wall of the threaded mounting hole 6, so that the threaded mounting hole 6 can be blocked. Moreover, since the diameter of the annular airbag 304 can be changed, the sealing structure 3 can be adapted to any model of motor body 1.

[0030] See also Figure 4 This embodiment further illustrates other embodiments. The magnetic block 5 is fixedly embedded in the center of the upper end of the pressure plate 305 . The magnetic block 5 can absorb the metal shell of the motor body 1 .

[0031] In this embodiment, after the blocking structure 3 is disassembled, the personnel adsorb the blocking structure 3 onto the outer shell of the motor body 1 through the magnetic block 5, which can effectively prevent the blocking structure 3 from shaking.
