It states inside the other half described turn trough of insertion of sliding pearl, the two sides up and down in gap are mounted on gear between the outer shaft and the inner shaft
Circle, the retaining ring both ends are welded with the connector in the outer shaft top exterior walls, are provided with screw hole on the connector, described
Turn trough is provided with the groove on the outer shaft inner wall in two sides up and down；Two sides are provided with positioned at described the pearl slot up and down
Flange collar on inner shaft outer wall.
Preferably, there are the gaps of 0.5cm between inner shaft outer wall after mounting for the retaining ring.
Preferably, the position of the groove is corresponding with flange collar, and flange collar is embedded in inside grooves.
Preferably, contactless between the flange collar outer wall and groove inner wall.
Compared with prior art, the utility model has the beneficial effects that by above and below outer shaft and inner shaft between two sides
Gap location is respectively mounted retaining ring, and fixed between the connector and outer shaft that retaining ring passes through its both ends, and retaining ring after mounting with inner shaft
There are gaps between top exterior walls, to not interfere the rotation of inner shaft, are entered inside pearl slot using two retaining rings come blocks dust.
By above and below pearl slot two sides be respectively provided with the flange collar on inner shaft outer wall, and in the outer shaft in portion be arranged two with flange collar position
Set corresponding groove, after mounting, two flange collars are respectively connected to two inside grooves for inner shaft and outer shaft, and flange collar not with it is recessed
Slot inner wall is in contact, to not influence the rotation of inner shaft, plays the secondary barrier effect to dust using flange collar, is located at pearl slot two
Two flange collars of side and two retaining rings can effectively ensure to will not fall into dust inside pearl slot.
