The utility model discloses a cut-to-size saw convenient for cutter angle adjustment, which relates to the technical field of cut-to-size saws, and comprises a machine body and a threaded rod, a motor is arranged in the machine body, the output end of the motor is fixedly connected with a saw blade, and the top of the machine body is provided with a limiting plate. According to the cut-to-size saw capable of conveniently adjusting the angle of the cutter, a second connecting rod is driven by a handle to rotate, the second connecting rod can drive a driving gear to be meshed with a driven gear, and when the driven gear rotates, a worm can be driven to be meshed with a worm gear, so that a connecting shell rotates, and the angle of a saw blade on one side of the connecting shell is also changed; at the moment, a wood board can be cut at different angles, a driving gear and a driven gear can do decelerating motion when being meshed, so that a connecting shell rotates more slowly, the adjusting precision is improved, meanwhile, force needed when a handle rotates can be correspondingly reduced, and the angle of a saw blade can be adjusted more easily.

The utility model discloses a circular ring line drawing device which comprises a working table, a driving assembly and a supporting piece which are oppositely arranged are installed above the working table, one end of a jig is connected with the output end of the driving assembly, the other end of the jig is placed above the supporting piece, and a line drawing assembly corresponding to the jig is further installed above the working table. The circular ring product to be marked is installed through the jig, the jig is driven by the driving assembly to rotate, the marking assembly acts on the circular ring product to achieve marking, multiple circular ring products can be marked at a time, and the marking device has the advantages of being high in marking efficiency and low in labor intensity.

The utility model discloses drum-type grain drying equipment which comprises a drum, a sleeve is sleeved outside the drum, one side of the drum is an opening side, the other side of the drum is communicated with a feeding pipe, a spiral blade is arranged in the drum, one side, corresponding to the feeding pipe, of the sleeve is communicated with a hot air pipe, and an air hole is formed in the position, corresponding to the communication position of the hot air pipe, of the drum. The roller rotates axially under the action of the driving device and is used for moving grains entering from the end side feeding pipe to the opening side on the other side, the grains continuously roll over in the driving process of the spiral blades, hot air entering from the hot air pipe enters the roller through the air holes and flows from one side of the roller feeding pipe to the opening side on the other side, and the grains are conveyed to the opening side on the other side. The roller can heat and dry grains in a rolling state, the roller can be used without shutdown, the roller rotates slowly, and sufficient drying time can be achieved.

The utility model discloses an electronic rearview mirror anti-interference test device comprising a main body, one side of the outer wall of the top of the main body is provided with a motor through a bolt, the output end of the motor is provided with a worm arranged in the groove of the main body through a coupling, and the inner part of the main body is movably provided with a screw rod extending to the groove in the main body through a bearing. The outer wall, close to the worm, of the screw is provided with a worm gear through a bolt, and the outer wall, located in the main body, of the screw is in threaded connection with a movable frame. Through the arrangement of a stepping motor, when the stepping motor is started, the stepping motor drives a placement plate to rotate under the action of a rotating rod, transmission wheels and a transmission belt, and the placement plate rotates more slowly under the action of a larger transmission wheel and a smaller transmission wheel, so that the material detection effect is improved; and the movable frame and the radiation emitter can be stably driven to move under the action of the motor, the worm, the worm gear and the screw rod, so that the practicability of the device is improved.

The invention relates to the technical field of component sorting, in particular to full-automatic component sorting equipment which comprises a base, a plurality of vertical plates are fixedly connected to the upper surface of the base, the vertical plates jointly penetrate through and are fixedly connected with a screening plate, and a plurality of feeding hoppers are fixedly connected to the lower surface of the screening plate; a conveying pipe is fixedly connected to the lower surface of the feeding hopper in a penetrating mode, and an open hole is formed in the conveying pipe; a preliminary screening mechanism is arranged on the screening plate and is used for preliminarily screening the components according to the sizes of the components; the device comprises a base, multiple sets of secondary screening mechanisms are arranged on the base, each secondary screening mechanism is composed of a detection control assembly and a guide control mechanism, the detection control assemblies are used for conducting different control according to different components, and the detection control assemblies are arranged on the base. The sorting equipment has the advantages that the probability of wrong sorting can be reduced, meanwhile, the sorting efficiency is higher, and the equipment cost is lower.

The utility model discloses quartz crucible finished product heat treatment equipment, including furnace body, high temperature steam generator, steel pipe, crucible body, low speed motor, driving gear, gear ring, barrier net, arc shell, annular pipe, connecting pipe, nozzle, rotating block, connecting block, limiting block, fixed pin no.

This invention relates to a street light pole for quick replacement of street light heads, belonging to the field of lighting equipment technology. It includes a lower section of the light pole vertically supported on the ground, an upper section of the light pole rotatably connected to the top of the lower section, and a mounting bracket for installing the street light head, located at the top of the upper section. The top of the lower section is rotatably connected to the middle of the upper section. A steel wire rope is provided at the bottom side of the upper section, and a fixed pulley is rotatably provided at the bottom side of the lower section. The steel wire rope is wound around the fixed pulley. Slowly rotating the fixed pulley releases the steel wire rope and causes the upper section to rotate from a vertical to an inclined position. Its advantages are that it makes street light head replacement faster, more convenient, and safer.
