Further, said middle segmentum intercalaris has axial hole, is provided with spring in the axial hole of the middle segmentum intercalaris between adjacent two square bodys.
Further, the two ends of the radial direction through hole of said major axis have the short sleeve locating slot.
Further, said pin is through riveting two short sleeve axially locating.
Compared with prior art, the beneficial effect of the utility model is:
1, the universal joint of the utility model has good tortuosity, can pass the crooked passage of whipstock smoothly.The universal joint of the utility model has higher intensity again simultaneously, can bear bigger moment of torsion, satisfies the needs of perforate.
2, the universal joint of the utility model can be adjusted the length of universal joint through the number of segmentum intercalaris in the increase and decrease, to meet the different needs.
3, the two ends of the universal joint of the utility model are provided with end connection joint, have different interfaces and are used for being connected with different workpiece, and are applied widely, connect rapidly.
4, the universal joint long service life of the utility model reduces the turnover rate of universal joint in the work, increases work efficiency, and also easy to operate, Safety performance is good, has very strong practicability and Economy.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail, but not as the qualification to the utility model.
Fig. 1 is the structural representation of preferred embodiment of the universal joint of the utility model.As shown in Figure 1, universal joint, comprise the end that is used for being connected that is arranged at two ends with other workpiece connect joint 1 and be used for adjusting the segmentum intercalaris 6 of length and be used for the end connect joint 1 and segmentum intercalaris etc. each save between the connecting assembly of usefulness of connection.Fig. 4 is the structural representation that the end of preferred embodiment of the universal joint of the utility model connects joint; Fig. 5 cuts open figure for the structure of the end connection joint of the preferred embodiment of the universal joint of the utility model.Like Fig. 4 and shown in Figure 5, the end that the end connects joint 1 is a workpiece connecting end 102, is used for being connected with other workpiece.This workpiece connecting end has connecting thread, is connected with other workpiece through screw thread.Connecting thread can be that internal thread also can be an outside thread.Certainly this workpiece connecting end also can be that other modes such as pin riveted joint, welding or interference fit connection are connected with other workpiece.The other end that the end connects joint 1 has two relative engaging lugs 101.The workpiece connecting end of the end connection joint 1 at two ends can be identical, also can be different.Fig. 3 is the structural representation of middle segmentum intercalaris of preferred embodiment of the universal joint of the utility model; As shown in Figure 3, the two ends of middle segmentum intercalaris 6 have two relative engaging lugs 601 respectively, and two relative engaging lugs of an end and two relative engaging lugs of the other end are 90 degree that circumferentially interlace and are provided with.Middle segmentum intercalaris 6 has axial hole 602.Fig. 2 is the structural representation of connecting assembly of preferred embodiment of the universal joint of the utility model; As shown in Figure 2, connecting assembly comprises the square body 2 with criss-crossing through hole, the major axis 4 with radial direction through hole 401, first short sleeve 301 and 302 two short sleeves of second short sleeve, and a pin 10.Fig. 6 is the structural representation of major axis.Fig. 7 cuts open figure for the A-A of Fig. 6.Like Fig. 6 and shown in Figure 7, the two ends of the radial direction through hole 401 of major axis 4 also have short sleeve locating slot 402 respectively, are used for respectively the short sleeve of its both sides being located.Segmentum intercalaris or middle segmentum intercalaris are connected with the end between the joint through the connecting assembly connection in adjacent two.The example that is connected to segmentum intercalaris among end connection joint and.The end of square body 2 and one of which side is connected the two engaging lugs connection of joint through major axis 4; 302 two short sleeves of first short sleeve 301 and second short sleeve are connected two engaging lugs of the middle segmentum intercalaris 6 of square body 2 and opposite side thereof respectively; The radial direction through hole 401 that pin 10 passes on first short sleeve 301 and 302 two short sleeves of second short sleeve and the major axis, and with first short sleeve 301 and 302 two short sleeve axially locating of second short sleeve.Certainly, also can modes such as clamp or nut be set two short sleeves are carried out axially locating through end at pin.Perhaps adopt interference fit that the mode of welding is set.Pin 10 can be through riveted joint with two short sleeve axially locating.Be provided with spring in the axial hole of the middle segmentum intercalaris between adjacent two square bodys.The setting of spring makes between joint and the joint of universal joint and keeps certain crowded thrust, and screens, the friction of facing two internodes mutually when preventing the universal joint distortion make the fairing more of universal joint bulk deformation, thereby improve the overall performance of universal joint.The universal joint of the utility model is provided with engaging lug respectively through the two ends at middle segmentum intercalaris, and the engaging lug at two ends is the circumferential 90 degree settings that interlace, and introduced connecting assembly save with save between be connected.Connection part turns to more flexible according to firmly.
