Implant (10) having a shaft which is adapted in use to be embedded in bone tissue and which has an outer surface provided with a circumferentially-oriented roughness. The circumferentially-oriented roughness has first and second axial sections (19, 21) with each section comprising a series of circumferentially-oriented peaks which have a crest and which are axially spaced apart by troughs. The axial spacing (d) between the crests of adjacent peaks in the first axial section (19) is less than the axial spacing (3d) between the crests of adjacent peaks in the second axial section (21). Although the axial spacing between the crests of adjacent peaks in the first and second axial sections of circumferentially-oriented roughness differs, the first and second axial sections of circumferentially-oriented roughness are adapted in use to provide the same or substantially the same pitch.

The invention relates to the technical field of bridge demolition, and discloses a bridge demolition safety protection device which comprises a supporting mechanism, the supporting mechanism comprises a supporting base and a supporting positioning block, a positioning groove is formed in the upper side of the supporting base, and an inclined supporting column is arranged at the position, located on one side of the positioning groove, of the upper side of the supporting base. The supporting and positioning block comprises a supporting and positioning block body, and a supporting clamping groove is formed in the upper side of the supporting and positioning block body. A movable clamping block can be moved by pulling a shifting plate, a supporting positioning block is embedded in a positioning groove, a plurality of second positioning blocks are embedded in a designated position, the loosening condition can be avoided, then the shifting plate is loosened, a spring recovers deformation, and the movable clamping block is driven to abut against a supporting base; a worker can conveniently and preliminarily fix the supporting positioning blocks and the supporting base, then a corresponding screw rod sequentially penetrates through one set of first positioning blocks and then is fixed to the supporting base, and the worker can conveniently conduct installation.

The invention discloses a semi-trailer top locking device. The device comprises a first connecting plate, a second connecting plate and winding wheels, wherein a row of connecting blocks are welded tothe top surface of the first connecting plate, the connecting blocks are fixedly connected with steel wire ropes, and one ends, away from the connecting blocks, of the steel wire ropes are connectedwith the winding wheels; and two brackets are welded to the top surface of the second connecting plate, a winding shaft is rotationally connected between the brackets, and the winding wheels and the winding shaft are coaxially welded. According to the device, the first connecting plate and the second connecting plate are fixed at the top of the semi-trailer through threaded holes, the winding shaft and the winding wheels are rotated by rotating a hand wheel, to that the first connecting plate and the second connecting plate are tensioned, and the tensioned two connecting plates are fixed through a fixing band and a clamping groove, so that the aim of top locking is achieved; and in addition, the first connecting plate and the second connecting plate are connected with suckers through auxiliary rods, so that convenience is brought to the primary fixation for the semi-trailer.

The invention discloses a multifunctional intelligent tracing scale based on a scan code device. The multifunctional intelligent tracing scale comprises a tracing scale and a support column installedat one side of the tracing scale, and PCs installed at two sides of the top of the support column, wherein a fixed component is installed between the top of the support column and the PCs. The multifunctional intelligent tracing scale has a scientific, reasonable structure and is convenient to use; the fixed component is arranged, a T-shaped fixed block, a fixed groove, a positioning groove and aT-shaped connection block help fix the PCs preliminarily and limit the fixing position of the PCs; a thread through hole, a locking screw and a through wire hole help assemble and fasten the PCs and the T-shaped fixed block; the scale is easy to install and convenient to disassemble, and is convenient to maintain; a wire take-up assembly is arranged, the fixed base and a wire take-up roller help wind and organize a connection line of the PCs, so that lover-long connection line is prevented from twisting to cause damage; and a rubber sheet outside the wire take-up roller helps attach the wire to the wire-take up roller closer.

The invention relates to the field of high-density board hole punching devices with precise positioning function, in particular to a high-density board hole punching device with precise positioning function, comprising a main body mechanism, a limit mechanism, an interference mechanism, a driving mechanism, a cleaning mechanism and a lubricating mechanism mechanism; rotating the driving mechanism, so that when the driving mechanism rotates in the main body, the limit mechanism is driven to slide and clamp the high-density board, so as to facilitate the operator to initially fix the high-density board; When the limit mechanism slides, the unfixed sidewall of the high-density board is fixed, which also prevents the high-density board from being displaced by the impact force when the punching equipment is working; the limit mechanism slides, and the sidewall of the high-density board The cleaning mechanism squeezes, so that the cleaning mechanism cleans the dust on the side wall of the high-density board by the internal gas when sliding; the lubricating oil is injected into the main mechanism from the lubricating mechanism, so that the main mechanism can be disassembled more conveniently.
