Abstract: A bicycle stand includes a base unit, a first positioning rack, a second positioning rack, and two movable pull shaft units. The base unit includes a base and a support seat that is pivoted relative to the base horizontally. The support seat includes a pedestal and two ears. Each of the two ears has a first end connected with the pedestal and a second end provided with a limit slot. The first positioning rack includes two rods and a link. Each of the two rods is pivotally connected with one of the two ears. A first holding area is defined between the two rods.

Abstract: A bicycle stand includes a base, a front positioning rack and a rear positioning rack. The front positioning rack includes two uprights pivotally mounted on the base, a tensile spring biased on one of the two uprights, and an abutting member pivotally mounted between the two uprights to define a first placement zone between the abutting member and the two uprights. The rear positioning rack defines a second placement zone. Thus, the first placement zone, the second placement zone and the abutting member form a three-point support to hold a bicycle wheel. In addition, the angle between the first placement zone and the second placement zone can be adjusted in a determined range, so that the front positioning rack and the rear positioning rack are used to support bicycle wheels of different sizes.

Abstract: A bicycle stand contains a base, a connecting member, and an adjusting plate. The base includes a placing area, a first extending section, a second extending section, and supporting plate. The connecting member includes a receiving portion, and the adjusting plate includes a positioning area. The locking area has a circular hole for retaining a wheel. The supporting plate has a connecting section, the connecting section has a recess, and the receiving portion has two shoulders, the adjusting plate includes a longitudinal slot with a plurality of notches. Thereby, the bicycle stand is applied to fix a bicycle based on a placed height of a rear fork of a wheel.

Abstract: A m ulti-purpose hand tool assembly is equipped with a spring biased pressing button having a downwardly bent lateral edge which can be in firm registration with a retaining cut of a selective tool bit so as to make the tool bit held in place when external force is applied thereto. The pressing button is pivotally fixed in place by a pivot pin to the hand tool assembly. A plurality of tool bits, such as a screw driver, a knife, a spanner and etc., are pivotally mounted onto a bolt locked in place by a nut at one end of the hand tool assembly. Each tool bit has an end provided with a working head and an opposite end equipped with a mounting hole through which the bolt is led so as to permit the multiple tool bits to be selectively pivoted about the bolt. At the pivot end of each bit is disposed at least the retaining cut which can be registered with the downwardly bent retaining end so as to firmly hold each selective tool bit in an operation position.
