The invention discloses a combination cable shackle which is used for erecting cables, water and electricity heating pipelines and the like for industrial and mining enterprises. The combination cable shackle comprises a plurality of shackle bodies which are connected and combined, and shackle mounting holes are formed in the shackle bodies. The combination cable shackle is characterized in that a plurality of shackle mounting holes are formed in the shackle bodies and are provided with upper shackles and lower shackles, wherein cylinders, shackle falling-prevention claws and shackle cones are arranged on the upper shackles and the lower shackles, and the shackle falling-prevention claws are inserted into the shackle mounting holes, then are compressed in the shackle mounting holes, and stretched on shackle falling-prevention discs. The shackle falling-prevention claws have elasticity, upper shackle wing claws matched with the lower shackles are designed on the upper shackles, the upper shackle wing claws and the upper shackles are of an integral structure, lower shackle wing grooves matched with the upper shackle wing claws for use are designed in the lower shackles, and the lower shackle wing grooves and the lower shackles are of an integral structure. The combination cable shackle has the advantages that the matching and the stability are good, the hooking reliability is good, the cost is low, and the interval is adjustable and can be adjusted freely and conveniently.

Some embodiments of the invention relate to a rotation unit for a surveying device, in particular a laser scanner for optically scanning an environment and such a surveying device. The surveying device has a rotation unit having a rotation mirror, for deflecting an emission light beam and a reception light beam, and a rotation body implemented as a cylinder having a on a beveled, free end. The rotation body is implemented as a hollow cylinder having a cylinder bottom and a beveled cylinder wall on its free end. The hollow cylinder is connected coaxially with respect to its cylinder axis in a rotationally-fixed manner to a motor-driven shaft via the cylinder bottom. The rotation mirror is fastened in the region of its free end to the cylinder wall of the hollow cylinder so it is supported thereby.

The invention relates to a lifting ring fixing plate device with an adjustable length. The lifting ring fixing plate device with adjustable length comprises a fixed plate, a suture line segment, draught lines and loop turning lines, wherein the draught lines and the loop turning lines are arranged at the two ends of the fixed plate respectively; the fixed plate is provided with a plurality of suture line through holes matched with the shape of the fixed plate; the suture line segment penetrates through the suture line through holes in a certain threading manner to form a plurality of adjustable lifting rings on one side of the fixed plate and a double pressurizing self-locking knot on the other side of the fixed plate; the tail end of the suture line segment penetrates through a knot of the double pressurizing self-locking knot; and the length of each adjustable lifting ring can be adjusted by pulling the tail end of the suture line segment. The lifting ring fixing plate device with the adjustable length can be adapted to surgical channels with different lengths by adjusting the lengths of the adjustable lifting rings; the double-pressurizing self-locking knot can effectively ensure that the a ligament cannot have the fallback phenomenon in the operation process and lowers the risk of postoperative disengagement of the self-locking knot; and different numbers of the suture linethrough holes of the fixed plate can be matched with the suitable threading modes, so that the overall mechanical performance of the system is improved.

The invention provides a waterproof fastening shell. The waterproof fastening shell comprises an upper shell body and a lower shell body, wherein the upper shell body comprises an upper bottom surfaceand a waterproof glue binding wall which surrounds the upper bottom surface for one circle and protrudes downward; the waterproof glue binding wall is provided with a plurality of convex clamping hooks; the lower shell body comprises a lower bottom surface, and a first side wall and a second side wall which surround the lower bottom surface for one circle and protrude upward; the first side wallis arranged at the outer side of the second side wall; a clamping hook groove matched with the clamping hooks is formed between the first side wall and the second side wall; a U-shaped groove for containing the waterproof glue binding wall is formed in the second side wall. With the adoption of the technical scheme, the clamping hooks and the clamping hook groove are adopted, and the shell is clamped without the need of an additional tool clamp, so that the time and the clamp cost are reduced; the shell body is fastened by utilizing the clamping hooks, and rebound stress can be balanced, so that the risk that waterproof glue is separated from the two shells is effectively reduced; an additional screw locking procedure is not needed, so that the procedure cost is reduced; the waterproof glue is used for preparing a waterproof layer, so that the risk that a waterproof ring is not assembled in place is also avoided.

The invention discloses an atomizing nozzle which has a smaller front end face capable of being inserted into a medical catheter with a small diameter. The characteristic dimensions such as the cross section diameter of a main body of a better atomizing nozzle is smaller than 0.2 inch (0.5 cm). The main body of the nozzle is normally connected to an extension part, and the extension part has transverse flexibility so that one nozzle main body can penetrate through a pipe body along a non-linear access. The nozzle main body is generally connected to the extension part through a lap joint portion correlated with the nozzle main body. According to the better atomizing nozzle, a D<e>/O specific value smaller than 12.0, a D/O specific value smaller than about 18 and a D/D<e> specific value smaller than about 1.1 are achieved. Another atomizing nozzle comprises a vortex chamber which is located on the upstream of a jet orifice and is adjacent to the jet orifice and a near-end chamber wall with a portion humidified through fluid, and the portion humidified through the fluid is at least close to one part of a dome or another curved surface.
