Abstract: An intelligent automatic processing apparatus for spoke holes of bicycle rims is revealed. The apparatus includes a seat pivotally connected to a machine body and provided with a rotary base. A rim is clamped and fixed by clamping jaws on the rotary base and a control unit drives an incline unit to incline the seat connected at an angle desired for control of slopes of holes being drilled. The control unit also drives a rotary indexing power source to rotate the rotary base at different angles according to the numbers and positions of spoke holes desired. Thus a drilling assembly drills the spoke holes on the rim. Thereby the spoke holes with various angles can be drilled on different positions of the rim by the control unit which adjusts positions and inclination angles of the rim accurately. Therefore, the drilling of the spoke holes is more convenient.

Abstract: A bodybuilding assistor structure mainly includes at least two handles. The two handles are connected with two telescopic rods. A rotatable member is pivotally connected with each bottom end of the two telescopic rods, so that the two handles rotate freely through the rotatable member. A positioning member for positioning is disposed at a bottom edge of the rotatable member. During use, the two handles are fixed on the ground through the positioning member, so that a user can stand and then grip the two handles by hands and thus can conduct bodybuilding actions such as twisting the waist, swinging the hip, kicking a leg and running by using the two handles as fulcrum points, thereby achieving an effect of assisting with bodybuilding.

Abstract: A brake device and a brake system using the same are provided. The brake device mainly has a housing having one end oppositely connected to a top lid. A synchronization assembly accommodated with the housing has first and second end surfaces, through which active and passive brake cable sets penetrate. An active limiter is connected to the second end surface of the active brake cable set, and the passive brake cable set is connected to at least one passive limiter, at least one elastic member and at least one brake assembly. A rear wheel is firstly braked and then a front wheel is braked according to a ratio between the corresponding elastic members through the movements of the active and passive brake cable sets, the elastic member and the single synchronization assembly. Meanwhile, the overall size and the manufacturing cost of the brake device can be effectively and saved, respectively.
