The invention relates to a furniture connecting piece which is used for connecting two furniture parts requiring connection and comprises a pair of embedded parts A embedded in one furniture part, a pair of embedded parts B embedded in another furniture part, a pair of connecting pieces for connecting the embedded parts A with the embedded parts B, and a driving part for driving the connecting pieces to rotate, wherein the pair of connecting pieces is connected with the embedded parts A with the embedded parts B through thread structures to realize fixation of two furniture parts; the thread structures rotate around axes of the embedded parts A or the embedded parts B; and a tooth profile structure A is arranged at one end of each connecting piece. The furniture connecting piece has the following advantages: when one of the furniture parts is connected, the thread structures capable of rotating around axes of the embedded parts A or the embedded parts B are adopted to realize connection of the embedded parts A and the embedded parts B based on the original embedded part, and only one type of connecting pieces is needed to realize connection, so that varieties of the connecting pieces are simplified, and subsequent installation is facilitated.

The invention provides a testing tool for testing rotation fluency of bearings with different sizes, and relates to the technical field of bearing clamping; the testing tool comprises a backing plateand a clamping device, a support plate is fixedly mounted on the upper surface of the backing plate, and a bearing body is slidably connected to one side, away from the backing plate, of the support plate; the clamping device is arranged on the upper surface of the backing plate and comprises a sliding plate, the lower surface of the sliding plate is slidably connected with the backing plate, a connecting rod is fixedly connected to the side, away from the backing plate, of the sliding plate, a track plate is fixedly connected to the end, away from the sliding plate, of the connecting rod, anda sliding block is slidably connected to the inner wall of the track plate. A fixing block is fixedly connected to the side, away from the track plate, of the sliding block. According to the invention, the problem that the testing efficiency of testing the bearing smoothness is reduced due to the fact that the sizes of the bearings are different and the bearings with different sizes are limited to a certain extent when the bearings are fixed is solved.

The invention relates to a clamping device, in particular to a clamping device for nail driving. The technical problem to be solved is to provide the clamping device for nail driving which is characterized in that a nail can be clamped, so that people can drive in the nail conveniently, do not need to hold the nail by hands, and can be prevented from knocked injury, in addition, the drive-in depthof one nail can be consistent with that of another nail. The technical scheme is to provide the clamping device for the nail driving. The device comprises a holding rod, a swing rod, a first spring,an L-shaped frame, a sleeve, a cylinder body, a vertical sliding block and the like; the swing rod is hinged to the left side of the front side face of the holding rod, first grooves are formed in theleft side of the inner top of the swing rod and the left side of the top of the holding rod, and the first spring is connected between the bottom of the first groove at the lower portion and the topof the first groove at the upper portion. According to the device, the nail can be clamped by the cooperation between an arc-shaped plate and a clamping groove, the nail can be in contact with the cylinder body, then the cylinder body is knocked to move downwards, thus the nail can move downwards to be driven into a wooded board; the nail is not required to be held by hands, so that the hands areprevented from knocked injury; and by means of a prying device, people can conveniently pull the nail out of the wooden board.

The invention discloses a scraped car dismantling assembly line. A pretreatment station, a metal plate dismantling station and a power assembly dismantling station are arranged, dismantling treatmentconducted on a car can be effectively improved, the car dismantling efficiency and safety are improved, dismantled parts of the car can be conveniently classified, and the dismantled parts can be conveniently pressed through a squeezing assembly; and a supporting table can be driven to move left and right through a drive assembly, so that the scrapped car on the supporting table is conveniently moved to the positions of different mechanical hands to be dismantled, the whole process is finished automatically, and the work difficulty of a user is greatly reduced. Through the change of the numberand the positions of warped board sheets, warping operation of metal plates or the parts in different shapes is achieved, each warped board sheet is of a metal sheet structure and can conveniently extend into a hole in a to-be-dismantled position and conveniently warp out, and the warping effect of different positions, different sizes and different shapes can be achieved.
