The right wheel 4 is rotatably arranged at the right end of the right base 2.
The left base 1 and the right base 2 are connected through a conical positioning module.
The left base 1 and the right base 2 can only rotate around the axle center of the conical positioning module in a full angle.
The fastening assembly self-centers the tapered positioning module. Effectively improve the axiality of left base 1 and right base 2, harmony and smooth nature when strengthening left base 1 and right base 2 and rotating.
The fastening component strengthens the connection between the axes and the radial directions of the left base 1 and the right base 2. The connection strength between each component is improved.
Further, the tapered positioning module includes a tapered outer shell 102 and a tapered inner core 202. The tapered outer shell 102 is sleeved on the periphery of the tapered inner core 202. The conical outer shell 102, the conical inner core 202, the left base 1 and the right base 2 are all coaxial. The tapered outer shell 102 and the tapered inner core 202 are both rotatable relative to the hub. Because the conical outer shell 102 and the conical inner core 202 are both conical, when the two are abutted and matched, the axes can be automatically aligned, and the coaxiality and the connection tightness are improved.
Further, the left base 1 includes a left frame 101. The conical shell 102 is fixedly arranged at the right end of the left frame 101. The right base 2 includes a right chassis 201. The tapered inner core 202 is fixedly arranged at the left end of the right frame 201. The assembly and disassembly of the accessories are reduced, the assembly time is shortened, and the problem that the accessories cannot be assembled due to loss is effectively solved.
