Preferably, axial limit structure includes be arranged on Pipe protective joint two spacer pins and is arranged on two stopper slots of lower Pipe protective joint one end；The central axis of described spacer pin the most on the same line, and intersects and vertical with the central axis of upper Pipe protective joint；Described stopper slot is formed by interconnective minor face groove and long edge groove, minor face groove and long edge groove composition " L " shape, and the angle between minor face groove and long edge groove is more than 30 degree and less than 90 degree；Described stopper slot slides with spacer pin and is connected, when spacer pin puts minor face groove under, and stopper slot limits the axially-movable of spacer pin.
Preferably, upper Pipe protective joint and lower Pipe protective joint are respectively arranged with an annular boss, the central axis of annular boss and the central axes of place pillar；Place Pipe protective joint is divided into linkage section and shield segment, described spacer pin and stopper slot to be arranged on the linkage section of place Pipe protective joint by described annular boss.
Preferably, the linkage section of upper Pipe protective joint is provided with two platforms being parallel to each other, two platform place planes all with the central axis of the central axis of upper Pipe protective joint and spacer pin determined by plane parallel；Connecting of described lower Pipe protective joint is also equipped with two platforms being parallel to each other on end, and when upper Pipe protective joint is connected with lower Pipe protective joint, two platforms of two platforms of upper Pipe protective joint and lower Pipe protective joint are the most in the same plane；Described fixing seat is U-shaped deck, and the dual-side of U-shaped deck engages with two platforms of upper and lower Pipe protective joint respectively.
Preferably, the height of fixing seat is more than upper Pipe protective joint or the linkage section length of lower Pipe protective joint, but distance between two annular boss after being not more than upper Pipe protective joint and the engaging of lower Pipe protective joint.
This utility model simple in construction, easy for installation, utilize upper and lower Pipe protective joint that mandrel is played protective action, and Pipe protective joint makes it be connected reliably with lower Pipe protective joint by axial limit structure in utilization, lower Pipe protective joint is connected with pillar, is possible to prevent the catching phenomenon that flexible shaft core shaft coupling causes beyond Pipe protective joint with mandrel connecting portion during flexible axle uses.

Detailed description of the invention
This utility model combination type Pipe protective joint, including upper Pipe protective joint 1 and lower Pipe protective joint 3, described upper Pipe protective joint 1 and lower Pipe protective joint 3 are hollow tube-shape, and upper Pipe protective joint 1 is flexibly connected by axial limit structure with lower Pipe protective joint 3, between described upper Pipe protective joint 1 and lower Pipe protective joint 3, it is provided with fixing seat 2.Axial limit structure includes two spacer pins 4 being arranged on Pipe protective joint 1 and two stopper slots being arranged on lower Pipe protective joint 3 one end；The central axis of described spacer pin 4 the most on the same line, and intersects and vertical with the central axis of upper Pipe protective joint 1；Described stopper slot is formed by interconnective minor face groove and long edge groove, minor face groove and long edge groove composition " L " shape, and the angle between minor face groove and long edge groove is more than 30 degree and less than 90 degree；Described stopper slot slides with spacer pin 4 and is connected, when spacer pin 4 puts minor face groove under, and stopper slot limits the axially-movable of spacer pin 4.The central axes of an annular boss 5, the central axis of annular boss 5 and place pillar it is respectively arranged with on upper Pipe protective joint 1 and lower Pipe protective joint 3；Place Pipe protective joint is divided into linkage section and shield segment by described annular boss 5, and described spacer pin 4 and stopper slot are arranged on the linkage section of place Pipe protective joint.Be provided with two platforms being parallel to each other on the linkage section of upper Pipe protective joint 1, two platform place planes all with the central axis of the central axis of upper Pipe protective joint 1 and spacer pin 4 determined by plane parallel；Connecting of described lower Pipe protective joint 3 is also equipped with two platforms being parallel to each other on end, and when upper Pipe protective joint 1 is connected with lower Pipe protective joint 3, two platforms of two platforms of upper Pipe protective joint 1 and lower Pipe protective joint 3 are the most in the same plane；Described fixing seat 2 is U-shaped deck, and the dual-side of U-shaped deck two platforms with upper and lower Pipe protective joint 1,3 respectively engage.The height of fixing seat 2 is more than upper Pipe protective joint 1 or the linkage section length of lower Pipe protective joint 3, but distance between two annular boss 5 after being not more than upper Pipe protective joint 1 and the engaging of lower Pipe protective joint 3.
During use, assemble, lower Pipe protective joint 1, 3, and by fixing seat 2 with upper, lower Pipe protective joint 1, 3 are connected, owing to fixing seat 2 is U-shaped deck, the dual-side of U-shaped deck is with upper, lower Pipe protective joint 1, two planes of 3 all engage, make, lower Pipe protective joint can not rotate after connecting, go up simultaneously, lower Pipe protective joint 1, spacer pin 4 on 3 coordinates with stopper slot, in restriction, lower Pipe protective joint 1, the axially-movable of 3, ensure the reliable of connection, Pipe protective joint is divided into during using by this utility model, lower Pipe protective joint 1, 3 two parts, wherein shield segment is first connected with pillar, linkage section is attached after mandrel joint etc. all installs again, the length of applicable Pipe protective joint so can be chosen according to stroke adjustment, make the termination of mandrel joint without departing from Pipe protective joint.
