Abstract: A bike chain checker includes a base, an opening formed in the bottom of the base, a leaning portion extended from one sidewall of the base toward the opening, two threaded holes bored in another sidewall for respectively engaging with a chain wheel screw and a pointer screw. The pointer is freely hung downward. A marking line is marked under one of the threaded holes. A groove is formed on the top of the base for fitting a level bar, and the level bar fixed by a screw engaged with a threaded hole bored in a sidewall of the groove. Thus, the level bar is positioned horizontally if the pointer overlaps the marking line. If the chain does not overpass the level bar when pulled up, it represents the loose allowance of the chain is acceptable. But, if passing over, the chain is too loose, needing to be adjusted.

Abstract: A bearing positioning tool set includes a grip having an inner end fixed with a combining rod with a combining hole. One or more positioning press blocks to be fitted with the grip are respectively formed with different diameters and bored with a central insert hole and respectively formed with a first fitting member, a first holding edge, a second fitting member and a second holding edge. A combining member is combined with the combining hole of a grip. By having the fitting member and the holding edge of the positioning press block respectively contacting closely with the inner wall and the upper edge of a bearing, hammering force can be applied evenly to position smoothly and quickly the bearing in the insert hole of an axle. Further, each positioning press block is formed with two different diameters for matching with different-sized bearings.

Abstract: A removing tool for car-window edge strips includes a grip, a linking rod, a protective disc and a tool set. The protective disc is positioned between the grip and the linking rod, and the linking rod has a flat insert groove diametrically formed vertically for the tool set to insert therein and kept tight by screws. The protective disc can protect hands of a user from getting hurt during removing operation. The flat insert groove of the linking rod can be used for combining different tool sets for removing car-window edge strips and dried glue attached with the edge strips with convenience and quickness.

Abstract: A tool kit includes two opposite grips sets respectively provided with two combining plates connected by connecting rods having tools pivotally fitted thereon. Each combining plate of one grip set has its edge disposed with a rail groove having its center cut with a notch and its opposite inner walls respectively bored with a lengthwise engage slot. Each combining plate of the other grip set has its connecting edge secured with a position projecting rail corresponding with the rail groove, and having its center fixed with connecting projection matching with the notch of the rail groove and its opposite sides respectively provided with an engage bar to be inserted in the engage slot. Thus, mutual engagement of the rail grooves and the position projecting rails forms a large combination area to increase frictional force and enable the two grip sets to be stably combined together.

Abstract: A bearing-positioning tool set comprises a grip having an inner end fixed with a combining rod extending outward, the combining rod bored with a combining threaded hole; at least one positioning press blocks respectively formed with two different diameters the positioning press blocks to be fitted with the grip respectively bored with an insert hole in the center, each of two ends of the insert hole being formed with a groove; each the positioning press block formed with a first circular fitting member, a first circular holding edge, a second circular fitting member and a second circular holding edge; and a combining member threadably combined with the combining threaded hole of the grip for fixing the positioning press block in position; one end of the combining member being formed with an enlarged head.

Abstract: A tool set for assembling an automobile tapered bearing includes a pneumatic tool, a hammering tool, bolts and plural press blocks. The pneumatic tool consists of a rod having an annular blocking surface, a sleeve fitting around the rod, a compression spring received in the sleeve and fitting round a fitting portion of the rod, and a connector threadably combined with the rod. The hammering tool consists of a grip and a connecting rod extending from the grip and provided with a female-threaded hole, and the grip has a hammering end. Each press block is formed with an annular sloped surface and an annular blocking surface. One of the press blocks is selected to combine with the rod, so a pneumatic apparatus can drive the pneumatic tool to press and shift an automobile tapered bearing in an axle insert hole smoothly.

Abstract: An air tool is composed of a main rod, a sleeve, a compression spring and a connector. The main rod possesses a plugging bar, a blocking annular surface, and a through bar having a connecting portion in its end portion. The through bar is mounted with the compression spring and inserted in the sleeve. The sleeve has a blocking annular surface to block the compression spring. The connector is screwed with the end of the main rod. In addition, via the elastic counterforce of the compression spring, the impact of the air tool generated while operating the air tool can be weakened so as to prevent the air tool from being damaged and enable a user to hold the air tool easily.
