SUMMERY OF THE UTILITY MODEL
In order to realize the purpose, the utility model discloses the technical scheme who adopts is:
an easy-to-assemble crank, comprising:
a driving shaft hole arranged on the crank;
the gap is arranged between the driving shaft hole and the edge of the crank;
a fastening hole penetrates through the crank, and the penetrating direction of the fastening hole is perpendicular to the gap;
the tightening hole enables the width dimension of the gap to be changed by matching with the fastening piece, and further the radial dimension of the driving shaft hole is changed.
In a preferred embodiment of the present invention, the present invention further comprises:
the groove is formed in the first side of the crank, one end of the fastening hole is formed in the groove, and the other end of the fastening hole penetrates out of the second side of the crank;
the two groove surfaces are positioned on the crank, the groove surfaces are planes, and an included angle between the groove surfaces is a right angle;
the recess is adapted to receive a mating fastener head.
In a preferred embodiment of the invention, the crank is provided with an eccentric shaft, which consists of a step and a journal, the step keeping the journal away from the crank.
In a preferred embodiment of the invention, the step has a radial dimension greater than the journal.
In a preferred embodiment of the present invention, the crank is further provided with an oil storage tank, and the cross section of the oil storage tank is triangular.
In a preferred embodiment of the present invention, the fastening hole is composed of a first fastening hole and a second fastening hole, and a thread is disposed in the second fastening hole, the thread enabling a mating fastener to be tightened through the fastening hole by a width dimension of the gap.
The beneficial effects of the utility model reside in that:
the utility model provides an easily assemble crank adjusts drive shaft hole aperture through setting up a gap cooperation fastener between drive shaft hole and crank edge to make the installation between crank and drive shaft not rely on the purpose of frock.

Detailed Description
In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The detailed structure of the present invention will be further described with reference to the accompanying drawings and the detailed description.
An easily assembled crank with reference to fig. 1 to 3, mainly comprising: crank 10, gap 11, tightening hole 40, drive shaft hole 12 and eccentric shaft 20.
The crank 10 is provided with a first side 13 and a second side 14, respectively, and a recess 30 is provided on the first side 13. A fastening hole 40 is provided through the crank 10, the fastening hole 40 being composed of a first fastening hole 41 and a second fastening hole 42. Wherein, one end of the first fastening hole 41 is opened on the groove surface 31, and the other end is arranged on the gap 11; the second fastening hole 42 connects the gap 11 and the second side 14 of the crank. The groove faces 31 are two adjacent planes on the groove 30, and the angle between the groove faces 31 is a right angle so that the groove 30 can receive the protruding head of the fastener.
The gap 11 is arranged between the driving shaft hole 12 and the edge of the crank 10, and the radial dimension of the driving shaft hole 12 can be finely adjusted by changing the width dimension of the gap 11. The clearance is perpendicular to the fastener holes 40 in the crank 10. Threads are disposed in the second fastening hole 42 that allow a mating fastener to tighten the width dimension of the gap 11 through the fastening hole 40, thereby changing the radial dimension of the drive shaft bore 12.
The crank 10 is also provided with an eccentric shaft 20, the eccentric shaft 20 being formed of a step 21 and a journal 22, the step 21 spacing the journal 22 away from the crank 10, whereby the step 21 is of greater radial dimension than the journal 22. Preferably, the radial dimension of the step 21 is 12mm and the radial dimension of the journal 22 is 6 mm.
The crank 10 is further provided with an oil storage tank 15, and the cross section of the oil storage tank 15 is designed to be triangular for convenience in processing.
A synchronizing groove 16 is formed in the driving shaft hole 12, and the synchronizing groove 16 enables the output track of the driving shaft to be consistent with the crank 10.
