A automated test tube cap removal apparatus includes: a cap remover (11) with a cap removing position (P1) for test tubes (20) contained sample; a test tube rack (19) which holds a plurality of capped test tubes (20) upright in a row, and loads to cap removing position (P1); a clamping mechanism (87) which is disposed in the cap removing position (P1) and clamps the plurality of test tubes (20); and a cap removal unit (112) disposed in the cap removing position (P1) and configured to move upward to remove caps (23) from some of a plurality of test tubes (20) and move upward to remove caps (23) from the remaining test tubes (20), and the caps (23) moves upward in meshing and supporting method for removing caps (23) from other test tubes (20). The cap removal unit includes engaging members (121), a lift mechanism (108), a cap guide member (117).

An oil filter remover comprising a sleeve, having an interior surface, an exterior surface, an open end and a closed end with indentations on the interior surface, and a reservoir. The oil filter is slid into the oil filter remover and the oil filter is unscrewed, the excess oil being caught within the oil filter remover and collected within the reservoir.

The invention discloses an automatic cover opening device for a sample container. The automatic cover opening device comprises a rack, a clamping mechanism, a cover opening mechanism and a lifting mechanism, wherein the clamping mechanism is arranged on the rack and used for fixing and clamping the sample container and preventing the sample container from rotating and moving in the axial direction, the cover opening mechanism is arranged on the clamping mechanism and used for taking down a sample container cover, and the lifting mechanism is arranged on one side of the rack and used for driving the cover opening mechanism to ascend and descend. The automatic cover opening device further comprises a rotating mechanism and a waste cover recycling mechanism, wherein the rotating mechanism is connected with the cover opening mechanism and used for driving the cover opening mechanism to clamp and rotate the sample container cover, and the waste cover recycling mechanism is arranged on one side of the bottom of the rack and used for recycling the sample container cover taken down by the cover opening mechanism. According to the automatic cover opening device, clamping and rotating of the sample container cover can be achieved without two independent driving mechanisms, only a power-source-free cover opening head is arranged based on the sample container cover rotating mechanism, high cost is avoided, the number of fault points is reduced, and therefore the economic benefit is increased.

An object gripping device for removing and installing bulbs and other objects. The device has around its circumference three or more vertical gripping posts. The device uses a sun gear and planetary gears to transmit the user's twisting motion to a gripping force applied equally around the object's circumference. Furthermore, the gearing ratio can be adjusted to create more or less leverage or gripping force applied to the bulb or object. The device could also be applied to gripping any object that is semi-cylindrical in shape. For instance, a robot can use the invented gear system to pick up or grip objects in a factory, laboratory, hospital, space exploration or home setting. Instead of a handle used to rotate the sun gear a drive shaft can be attached. An electric motor, a gas or diesel engine, a hydraulic power pack can rotate the drive shaft.

A bottle cap remover includes a pair of axially nested socket sections of different diameters depending axially from a larger-diameter grasping section. Each of the socket sections includes frictional gripping members along their inner walls that are adapted to frictionally engage different sizes and types of metal and plastic bottle caps, thereby to enable the user to twist off and remove the bottle caps by applying a relatively small twisting force to the grasping section.

A multifunctional opener includes a main body having two opposite sides formed with two upright clamping portions and having an inside formed with an engaging recess located between the two clamping portions. Thus, the clamping groove and the engaging recess of the main body are used to open seal caps of different sizes, thereby enhancing the versatility of the opener. In addition, the clamping groove or the engaging recess of the main body is engaged with the periphery of the seal cap so that the seal cap is closely clamped by the main body, thereby facilitating a user opening the seal cap.

A tool for oil and fuel filters includes a generally cylindrical body having an open upper and a closed lower end. The body includes an interior chamber having a plurality of tapered radial projections that extend longitudinally within the interior chamber. The projections include respective tapered gripping surfaces that engage filters having respective diameters at corresponding depths within the chamber. The chamber defines a reservoir for collecting fluid that leaks when the filter is removed.

A non slip bottle cap opener (100) for installing onto a key ring or key chain with other keys is formed with the approximate length and thickness of a standard key to allow it to be comfortably carried on the key ring or chain like an ordinary key. The opener includes a pry element (120) formed with a narrow leading edge (140) for installing within the annular gap (60) between the bottle cap and the bottle top. The pry element further includes an engaging surface (165) that acts upon an inside surface of the annular lip of the bottle cap to forcibly engaged with the annular lip to prevent the opener from slipping off of the bottle cap.
