The invention discloses a camera module and a terminal device, and belongs to the technical field of electronics. The camera module comprises a rotatable reflector, a lens group, a shell and an image sensor; the shell comprises a first surface and a second surface; a first mirror surface of the rotatable reflector is a reflecting surface, and a part of the first mirror surface located in a first reflecting area is a first sub mirror surface; when the rotatable reflector is located at a first position, the first mirror surface reflects a first light signal, an image is generated after the reflected first light signal is transmitted along a straight line where an optical axis is located, when the rotatable reflector is located at a second position, the first mirror surface reflects a second light signal, and an image is generated after the reflected second light signal is transmitted along the straight line where the optical axis is located. According to the camera module provided by the embodiment of the invention, the function of double-channel shooting is realized by using just one rotatable reflector, thereby reducing the number of reflectors, shortening the size and saving the occupied space.

A plurality of tube-typed extension apparatus are arranged on an air flow guide device, the centre distances of the tube-typed extension apparatus are between 35 to 55mm, the tube-typed extension apparatus are communicated with the air holes which are arranged on the air flow guide device, separators are connected with the lower ends of tube-typed extension apparatus, reciprocators are separately connected with every separator, the reciprocators are composed of a swing board, a pick-up device and a fixed shaft, and the centre distances among the reciprocators are 35-55mm. The invention has the following advantages: a non-woven fabric which is made by the method has high density, the fiber web is uniform and the deviation ratio of the thickness and mass per square meter of the product is small.

The invention relates to the field of injection molding processing, in particular to a quick mould changing mechanism used for injection molding processing. The quick mould changing mechanism comprises an injection molding machine, a positive mould seat and a negative mould seat, wherein the positive mould seat and the negative mould seat are installed on the injection molding machine. The quick mould changing mechanism also comprises a positive mould, a negative mould, a clamping claw movement mechanism, an elastic tight-plugging mechanism, a mechanical clamping claw, a preheating mechanism,a placement frame and four demoulding mechanisms. The quick mould changing mechanism used for injection molding processing preheats a mould on the placement frame through a preheating mechanism so asto prevent a worker from transporting the mould, a possibility that the worker is at risk is lowered, a situation that the positive mould and the negative mould are clamped and installed for two timescan be avoided, and a mould replacement process is quickened. Since the positive mould is taken down from the negative mould, a possibility that mould installation has a deviation is lowered, the positive mould and the negative mould are tightly connected, only one-time clamping and disassembling needs to be carried out, a mould replacement process is quickened, a situation that the positive mould and the negative module are assembled by the worker is not required, the positive mould and the negative mould are assembled into a whole, and land occupation of the mould is reduced.

A structured light projection system including a substrate, a semiconductor laser chip, a first optical module, and a second optical module is provided. The semiconductor laser chip is electrically connected to the substrate. The first optical module is disposed on the substrate. The second optical module is disposed on the first optical module. The deviation rate between optical axes of the optical modules and the semiconductor laser chip and the calibration time thereof are reduced by the first optical module directly packaging the substrate through a primary optics design, so as to increase the yield of the structured light projection.

The invention relates to the field of injection molding, in particular to a working method of a quick mold changing mechanism for injection molding. The mechanism comprises an injection molding machine, a positive mold base and a negative mold base, the positive mold base and the negative mold base are arranged on the injection molding machine, and the mechanism further comprises a positive mold,a negative mold, a clamping jaw moving mechanism, an elastic inserting mechanism, a mechanical clamping jaw, a preheating mechanism, a placing frame and four demoulding mechanisms. According to the quick mold changing mechanism for the injection molding, a mold on the placing frame is preheated by the preheating mechanism, workers are prevented from carrying the mold, the possibility that the workers are dangerous is reduced, two times of clamping and mounting the positive mold and the negative mold are avoided, the process of replacing the molds is accelerated, the probability of deviation ofthe mounting of the mold is reduced due to the fact that the positive mold is taken down from the negative mold, the positive mold and the negative mold are tightly connected, only one time of clamping and dismounting is needed, the process of replacing the mold is accelerated, the workers are not needed to assemble the positive mold and the negative mold together, the positive mold and the negative mold are assembled together, and the occupied area of the mold is reduced.

The invention provides a multi-wire clamp universal live working tool and a using method thereof. The multi-wire clamp universal live working tool comprises an installation side plate, the installation side plate is provided with an upper hook arm and a lower hook arm which face to each other vertically and are stretchable and further provided with lead wire hook rods which are elastically stretchable, and the lead wire hook rod are located between the upper hook arm and the lower hook arm. A lead wire is fixed by the two lead wire hook rods with springs, then a wire clamp is opened by the upper and lower stretchable hook arms with springs to enable an opening of the wire clamp to be maximum, the error rate and deviation rate of wire clamp installation are significantly decreased, and convenience is brought to operation in actual work. In addition, the live working tool is encapsulated by adopting an insulating material and externally connected with a protection shell, the protection shell protects hooks and internal devices from being destroyed by collision, therefore, the safety coefficient can be better improved, and the safety of a worker is guaranteed.
