An electrical contact (100) of an audio jack connector includes a main portion (10), a soldering portion (30) bending from a lateral edge of the main portion, an elastic portion (20) extending curvedly from a distal end of the main portion to be located above the main portion. The elastic portion has a flexible beam (21), a first arm (22) extending upwardly from the flexible beam and a second arm (23) curvedly bending from the first arm. The first arm and is consistent with a direction along which an audio plug connector is inserted. The second arm is adverse to a direction along which the audio plug connector is withdrawn.

A locking device for a vehicle seat has a latch which is mounted pivotably about a second axis and is intended for locking a counter element, with a clamping eccentric which is mounted pivotably about a first axis parallel to the second axis and, by interaction with a first functional surface of the latch, secures a locked state of the latch. In the locked state, the clamping eccentric acts in a spring-loaded manner on the first functional surface via a clamping surface. The clamping eccentric is moveable from the locking position thereof into the unlocking position thereof. A pretensioned compression spring is provided, which is supported at one end thereof on an arm of the clamping eccentric in a manner spring-loading the latter into the locking position thereof and, at the other end thereof, acting upon the latch in the unlocking direction.

The invention belongs to the technical field of tool equipment, and discloses a high-efficiency disassembling tool for an inner ring of a bearing. The high-efficiency disassembling tool for the innerring of the bearing is applied to disassembling the bearing on a shaft; a gear is arranged on the shaft; the disassembling tool comprises a closed disassembling ring provided with an inner hole and formed by sequentially connecting multiple sub disassembling rings; a circumferential groove is formed at the position, installed and combined with the bearing, of the gear so as to be used for the closed disassembling ring to embed; the first end surface of the embedded closed disassembling ring fits to the end surface of the inner ring of the bearing; the second end surface of the embedded closeddisassembling ring fits to the side wall of the circumferential groove in the gear; the inner hole wall of the closed disassembling ring fits to the groove bottom of the circumferential groove; and multiple ejection mechanisms capable of being abutted against a gear web so as to enable the closed disassembling ring to drive the bearing to separate and displace along the axial direction of the shaft are uniformly distributed on the circumferential direction of the closed disassembling ring. The multiple sub disassembling rings are combined into the closed disassembling ring, the inner ring of the bearing can be easily returned to the position on which the inner ring of the bearing can be easily taken out through the ejection mechanisms abutted against the gear web so as to enable the innerring of the bearing to separate, and the tool can adapt to disassembling bearings under different conditions of various bearing installation position.

The present invention relates to a crimping tool, in particular crimping pliers. The crimping tool comprises crimping die halves having a resilient deformation region. At the end of a crimping process the resilient deformation region is elastically deformed with the result that the crimping contour opens and contour parts automatically move apart. Accordingly, the crimping contour “breaks free” from the work piece for an ease of the removal of the work piece from the crimping tool.

A hand-held, multi-channel pipettor has an electronically controlled motor to reposition pipette tips for different center to center spacing. Each repositionable tip fitting assembly has a cam following pin that is driven by cam tracks in a motor driven roller drum. Stationary ports for the multiple aspiration cylinders are strategically placed to simplify management of flexible tubes leading to the repositionable pipette tip fitting assemblies. The pipettor has a user interface that can be operated conveniently by one hand to reposition pipette tips. It has a pipette tip ejection mechanism with a sinusoidal stripper bar.

A vertical circulation type intelligent stereo garage u-turning mechanism comprises a jacking device and a rotating device. The rotating device comprises a rotating fluted disc which is located on a base and is connected with and bears the jacking device and a motor reducing gear driving the rotating fluted disc to rotate. The jacking device is composed of a jacking lead screw installed on the rotating fluted disc, a synchronous belt wheel, a synchronous belt and a jacking motor reducing gear. The jacking device and a car containing plate are of a separated structure. Stable rotation and high operation efficiency are achieved, the jacking force of the jacking device is improved, and the internal garage space needed in the steering u-turning motion process of the u-turning mechanism is reduced. The u-turning mechanism is used for automobile u-turning when cars are stored in an intelligent stereo garage, a vertical circulation type intelligent stereo garage and a twin-tower vertical circulation type intelligent stereo garage.

The invention relates to an intelligent coal mine support, comprising a supporting plate, the supporting plate is hingedly installed with a connecting plate, the connecting plate is connected with a cover beam, the cover beam is hingedly installed with a top beam, and the supporting plate is hingedly installed There is a No. 1 hydraulic cylinder connected to the top beam. The top beam is connected with a supporting device to prevent the top beam from overloading and rotating. The top beam is also equipped with a reinforcement device to increase the bearing capacity of the top beam. The No. 1 hydraulic cylinder, Both the support device and the reinforcement device are connected to a controller. The invention supports the top beam through the cooperation of the non-return rod and the ratchet to prevent the top beam from turning over and causing underground landslides, endangering the safety of workers; the invention enhances the jacking force of the No. 2 hydraulic cylinder through the cooperation of the reinforcing rod and the U-shaped plate, preventing The damage to the No. 2 hydraulic cylinder causes the top beam to turn over and cause landslides; the invention drives the chain wheel to rotate and quickly releases the swing rod through the chain, and at the same time, the No. 3 hydraulic cylinder drives the support rod to support the top beam to prevent the top beam from being overloaded and collapsed, buying time for workers to escape.

The invention belongs to the technical field of machining, and particularly relates to a nested cutting machining device for a boron carbide material workpiece. The nested cutting machining device comprises an electric spark machine tool, an electrode mounting body which is mounted on a spindle of the electric spark machine tool, and a workpiece mounting body which is mounted on a platform of the electric spark machine tool. Boron carbide material part workblank which is machined through the nested cutting machining device is high in precision of dimension, form and position and high in surface roughness precision, the thickness of an electric corrosion layer can be effectively controlled, and the problem that cracks and collapsing slag are likely to be generated when boron carbide materials are machined is solved.
