The invention discloses a packaging machine for packaging rice bags. The packaging machine comprises a fixing rack, a sub-bagging device and a bag opening device, wherein the sub-bagging device comprises a vacuum machine, a lower vacuum sucking tube and an upper vacuum sucking tube; the lower vacuum sucking tube is fixed below one end of the fixing rack; one end of the lower vacuum sucking tube is communicated with a vacuum machine sucking hole; a lower nozzle which is opened upwards is arranged at the other end of the lower vacuum sucking tube; one end of the upper vacuum sucking tube is communicated with the vacuum machine sucking hole; an upper nozzle which is opened downwards is arranged at the other end of the upper vacuum sucking tube; the upper nozzle is arranged above the lower nozzle; the bag opening device comprises two rotating rods and a bracket; the two rotating rods are respectively arranged vertically and are fixed on the bracket through bearings; the two rotating rods are in transmission connection with the transmission device, so that the two rotating rods rotate simultaneously in a same direction; bag support rods are arranged at the lower parts of the rotating rods, so that the bag support rods enter the packaging bag openings or the bag support rods are reset when the rotating rods rotate in the opposite direction; the bracket is used for driving a discharge hole through the transmission device; the discharge hole enables the lower parts of the rotating rods and the packaging bags of which the openings are opened to extend into a discharge device. The packaging machine is convenient to use and low in production cost.

The invention provides a test probe device comprising a needle bed main body, a test needle, a plastic spring bracket and a pressure sensor, wherein the needle bed main body comprises a fixed seat, a test needle fixer, a U-shaped pressure adjuster and a pressure sensor fixed part; the test needle comprises a knife-type test probe and a signal output line connected with the test probe; the signal output line is connected with the fixed seat at the back end of the main body; the test needle is fixed on the plastic spring bracket, and the plastic spring bracket is fixed at the front end of the needle bed main body; the pressure sensor comprises a pressure sensor main body, a pressure data conducting wire and a pressure data conducting wire connector; the pressure sensor main body is fixed onthe upper surface of the needle bed main body via the pressure sensor fixed part; the pressure data conducting wire is connected with the pressure sensor main body and the pressure data conducting wire connector; and light reflected bars are arranged below the induction device of the pressure sensor and at the upper surface of the plastic spring bracket.

The invention discloses an adjustable intelligent bicycle. The adjustable intelligent bicycle comprises a front wheel, a back wheel, a front fork, handlebars, a chain wheel, pedals and a bicycle seat,and is characterized by also comprising a beam connected with the front fork and the bicycle seat, a front slant beam connected with the front fork and the chain wheel and a back slant beam connectedwith the back wheel and the front slant beam; an installing groove is formed in the length direction of the front slant beam, and an installing hole is formed in the end, close to the front slant beam, of the back slant beam; the pedals comprise pedal shafts and pedal frames, supporting pipes are arranged in the pedal frames, sleeve the pedal shafts and are rotationally connected with the pedal shafts, thread heads extending out of the supporting pipes are arranged at one ends of the pedal shafts, connecting columns are arranged at the other end of the pedal shafts, the connecting columns andthe pedal shafts are coaxial and are of an integrated structure, gaskets are arranged on the connecting columns, limiting protruding rings formed by spin rivets are formed in the outer ends of the connecting columns, and end covers are arranged at the ends, close to the limiting protruding rings, on the supporting pipes; supporting sleeves are also arranged at the two ends of the pedal shafts, and rotating sleeves are arranged between the supporting sleeves and the supporting pipes.

The invention discloses a transfer support vehicle. The transfer support vehicle comprises a vehicle frame, wheel type structures arranged on the two sides of the vehicle frame in the first directionand adjusting mechanisms connected with the vehicle frame and the wheel type structures. Each adjusting mechanism comprises an adjusting part and a moving part, one end of the moving part is connectedwith the adjusting part, and the other end of the moving part is connected with the corresponding wheel type structure; and the adjusting parts are used for adjusting the moving parts to move in thefirst direction relative to the vehicle frame so as to drive the wheel type structures to get away from or get close to each other in the first direction. According to the transfer support vehicle provided by the embodiment of the invention, by arranging the adjusting mechanisms, the distance between the wheel type structures arranged on the two sides of the vehicle frame can be conveniently adjusted, and therefore the application range of the support vehicle is widened.

The invention discloses a splicing structure matched with a metal armoring for a withdrawal-type switch equipment cabinet body, consisting of a first cabinet body (1), a second cabinet body (2) and a splicing structure (3), wherein the first cabinet body (1) and the second cabinet body (2) are spliced together with each other by the splicing structure (3); the first cabinet body (1), the second cabinet body (2) and the splicing structure (3) are connected with one another in sequence by bolts and nuts; the splicing structure (3) adopts a frame type; the width of the cross section of the splicing structure (3) can be determined according to the original fundamental dimension and the current metal armoring withdrawal-type switch equipment switch body, thus very conveniently adjusting the distance between the two cabinet bodies; therefore, the dimension of a reconstructed cabinet body can be well matched with the original fundamental dimension; and the cabinet body and the splicing structure can be well connected with each other by the form of the bolts and the nuts, thus being operated simply and conveniently.
