摘要： A jack with a leg (1) and a supporting arm (2) articulated together by an articulation (3). The leg rests against the ground (5) by way of a foot (4). The supporting arm is articulated by another articulation (18) at the other end of the supporting arm to a load-support plate (19). The plate supports the vehicle as it is lifted by way of an innermost section (20) located preferably between the sill ridge (21) and the midline, and below the bottom (22), of the vehicle. The plate has a bodywork catch (25) with a bent-up section (26). The bent-up section comes to rest against the outside (23) of the sill (24) when the jack is used and is raised by a spring (28). Adjusting arms (9& 10) are articulated to the leg, to the supporting arm, and to each other, constituting a parallelogram linkage. One end (17) of the supporting arm projects beyond its articulation (7) to its associated adjusting arm (9). A threaded displacement shaft (12) is connected at one end to an articulation (11) between the adjusting arms and at the other to the articulation (3) between the leg and the supporting arm.

摘要： A vehicle jack of the type known as "Y-jacks". It has a base plate (1) with perforated fins that receive and fix, in a particular way, the protruding necks on the wings of the jack body. A nut (13) is secured to the end of the body, with easy entrance into the end and fixed by some lugs (14) which are bent over the central portion of the nut. The arm (3) of jack also has two protruding necks towards the interior, on which a cross member is received, formed by a part with a U-shaped section whose wings or sides clasp on to the necks, are made with U-shaped openings. The base of the cross member is controlled by a special easy entrance holder plate on the housing on the arm. An arm (30) of a specially designed shape acts in combination with a holder plate-cross member, whose seating for the vehicle has a metal insert. This holder plate-cross member is provided with an external retainer on which the end of the screw spindle is supported. These features eliminate conventional parts and provide for fast efficient assemble of the different components.

摘要： A multi-usage electric tool includes an angle-changeable grip, a main body and an electric tool head. The grip and the main body are formed with corresponding inclined adjoining faces for movably connecting the grip with the main body. The inclined face of the grip is disposed with a guide rib and the inclined face of the main body is disposed with an arch guide slot. The guide rib is slidably fitted in the guide slot, whereby the grip can be rotated relative to the main body through a certain angle along the guide slot so as to change the angle contained by the grip and the main body. One end of the main body is disposed with an engaging mechanism and one end of the tool head is disposed with an engaging mechanism corresponding to the engaging mechanism of the main body for detachably engaging the tool head with the main body. The tool head is easily replaceably assembled with the main body, whereby a user can conveniently change the tool head for different usages.
摘要翻译： 多用途电动工具包括可变角的手柄，主体和电动工具头。 把手和主体形成有用于将把手与主体可移动地连接的相应的倾斜邻接面。 把手的倾斜面设置有导向肋，主体的倾斜面配有拱形导槽。 引导肋可滑动地装配在引导槽中，由此手柄可以相对于主体沿着引导槽旋转一定角度，以便改变手柄和主体所包含的角度。 主体的一端设置有接合机构，工具头的一端设置有与主体的接合机构对应的接合机构，用于将工具头与主体可拆卸地接合。 工具头可以容易地与主体组装，由此用户可以方便地改变工具头以用于不同的用途。

摘要： A vehicle jack with an upright assembly and an arm articulated thereto around a fixed horizontal axis. The free end of the arm bends toward the vehicle and is directly or indirectly raised away from and lowered toward the ground by a spindle. To simplify obtaining an angle in the arm, the main section of the arm is straight and an angled section is form fit onto its free end.

摘要： A driving joint includes a joint block secured to an output shaft of an electric driving unit, and a U-shaped connection plate connected at its opposite ends to the joint block and provided at its front wall with an elongated connection hole. The connection plate can be engaged within the U-shaped driven joint, and the elongated connection hole can be fitted to a connection plate of a T-shaped driven joint. With this arrangement, various types of jacks having different types of driven joints can be driven by a single electric tool.

摘要： Pivot for articulating the load-bearing components of a jack. The pivot comprises a shaft that rotates in a bore. The components are lengths of U section or have lateral flanges or upright edges that overlap in the vicinity of the pivot. The object is to decrease the weight of the jack. Instead of a solid bolt, the axis is a hollow neck (19) stamped through the sides (15 & 17) or flanges (13) of one component and extending through the bore (18) in its counterpart.

摘要： An automotive jack in which an upright member is provided with a pivotable base plate hinged on a first pivot at the bottom of the upright member. This upright member has a second pivot on which a supporting arm is turnable. The supporting arm is pivoted by an actuating device. A spring pivots the base plate along the length of the upright member, and the supporting arm has, at one end, a load interception head for pivoting the base plate through a stop against the force of the spring into a position at an angle to the length of the upright member when the jack is folded together. The sole of the base plate has an entire surface butting against the ground for any extensions and loads of the jack due to the pivoting of the base plate about the first pivot.
