Wheel shaft.
To achieve these goals, the utility model employs following technical solution：A kind of level-one driving gear shaft, including
Driving gear shaft, center position is socketed with bearing, and positioning pin is welded on bearing on the driving gear shaft, the active
Bearing side is provided with position-arresting disk on gear shaft, the side that position-arresting disk is located on the driving gear shaft is socketed with gear
Disk offers keyway on the driving gear shaft, and one end of the driving gear shaft offers external screw thread, the toothed disc side
Gag lever post is welded on table wall, and one end of gag lever post is provided with elastic clamping block, and cooperation gag lever post is offered on the position-arresting disk
The limit hole used, and the engaging slot for being internally provided with cooperation elastic clamping block and using of limit hole.
As further describing for above-mentioned technical proposal：
The radius of the toothed disc is more than the radius of position-arresting disk.
As further describing for above-mentioned technical proposal：
There are two the positioning pin is set altogether, and two positioning pins are symmetrical about the horizontal central line of bearing.
As further describing for above-mentioned technical proposal：
There are four the gag lever post is set altogether, and spacing is equal between any two for four gag lever posts.
As further describing for above-mentioned technical proposal：
There are four the limit hole opens up altogether, and four limit holes are mutually right about the horizontal central line of position-arresting disk between any two
Claim.
In the utility model, position-arresting disk is provided on driving gear shaft first, limit hole and engaging are offered on position-arresting disk
Slot, toothed disc are fixed by gag lever post and elastic clamping block on position-arresting disk, complete the fixation of driving gear shaft and toothed disc,
Such fixed form, toothed disc can be dismantled, and convenient for the replacement of toothed disc, and position-arresting disk is mutually clamped with toothed disc, limiting
Disk can play the role of support to toothed disc, improve the intensity of toothed disc, increase its service life, then have in driving gear shaft
Bearing is socketed at heart position, positioning pin is provided on bearing, the setting of bearing can improve the intensity of driving gear shaft, prevent
Only it causes the distortion or fracture of driving gear shaft, improves its service life, and positioning pin can block in use, stress is excessive
It closes in the fixed place of driving gear shaft, bearing is fixed by positioning pin, realize the limiting of driving gear shaft, improve master
The stability that movable gear shaft uses.
