The invention relates to a semiconductor refrigerated wearable cooling waistcoat. The semiconductor refrigerated wearable cooling waistcoat comprises a body surface temperature acquirer sewed, a human body heart rate acquirer and a semiconductor temperature adjusting mainframe, wherein the body surface temperature acquirer and the human body heart rate acquirer are sewed on the inner side of the waistcoat, the body surface temperature acquirer and the human body heart rate acquirer are respectively used for acquiring body surface characteristics of the body surface temperature of a human body and the human body heart rate and input the body surface characteristics to a central control unit of the semiconductor temperature adjusting mainframe in an electrical signal mode. The central control unit automatically performs water temperature adjustment according to the fed back human body characteristics and performs water temperature display and current display. The semiconductor temperature adjusting mainframe performs automatic heating and cooling switching through a program implanted by the central control unit. The semiconductor refrigerated wearable cooling waistcoat exposed in a heat source environment brings away human body heat through water circulation to achieve the cooling purpose and achieves the purpose of automatic circulating temperature control through real-time monitoring and feedback on the human body surface temperature, heart rate and other body surface characteristics of the human body and the predetermined program of the central control unit.

The portable dining table comprises two table boards, wherein the two table boards are hinged, two fixing holes, two first table legs and two second table legs are arranged in the bottom of each table board, fixing blocks are fixed to two sides of the outside of the fixing holes, one ends of the first table legs are positioned between the two fixingblocks, the ends, positioned between the two fixing blocks, of the first table legs, tally with the fixing holes, connecting holes are formed in the other ends of the first table legs, fixing sleevesare arranged outside the first table legs in a sleeving manner, connecting rods are arranged between the second table legs and the first table legs, connecting blocks are fixed at one ends of the second table legs, the connecting blocks tally with the connecting holes, and threads are arranged on the inner walls of the fixing sleeves and outer walls of one ends, close to the connecting blocks, ofthe second table legs. The portable dining table is reasonable in structure and ingenious in design, and is portable, and in addition, the height of the dining table can be adjusted, so that the demands of different people can be satisfied.

A portable photoelectric power source is consisted of a photoelectric board, an electric condenser and a stabilizer, wherein the photoelectric board is composed of a plurality of thin-striped polycrystalline solar cell sheets through series connection, and the electric energy transformed by the photoelectric board is stored with the electric condenser. the electric condenser is composed of a plurality of rechargeable batteries through series connection, and the stabilizer is used for stabilizing the output voltage. The present invention can store the electric energy generated by any irradiation such as sunlight and light, as well as can be used with recharging and discharging repeatedly.

The invention relates to a portable bicycle, which is characterized in that a bicycle seat frame is arranged on a lower bicycle frame; the portable bicycle comprises a bicycle seat, a seat rod, a rear upper fork and a rear upper fork frame; the lower end of the seat rod is connected with the front end of a front wheel accommodating groove of the lower bicycle frame through a seat rod shaft; the bicycle seat is arranged at the upper end of the seat rod; the upper end of the rear upper fork is connected with the seat rod through a rear upper fork shaft; the rear upper fork frame is fixedly connected with the rear end of the front wheel accommodating groove on the lower bicycle frame; a front bicycle frame, the seat rod, the lower bicycle frame and the rear upper fork are respectively made of two rectangular parallel flat plates which are arranged symmetrically, so that a front bicycle wheel and a rear bicycle wheel are inserted in a gap between the parallel flat plates when the bicycle body is folded, therefore the volume of the folding bicycle is largely reduced. On the condition of adopting a bicycle wheel with a diameter of 10 inches, the folded size of the portable bicycle disclosed by the invention is 64 cm * 25.4 cm * 9.5 cm; and the portable bicycle has the advantages of light weight, high folding speed and convenience and safety for riding.

The invention belongs to the technical field of anchor drilling machines, and provides an ultra-light portable trestle drilling machine. The ultra-light trestle drilling machine comprises a main supporting column for upward and downward jacking. A locking disc is arranged in the middle of the main supporting column, and is provided with a fixing shaft along the axis. A friction disc sleeves the fixing shaft, a fixing support is arranged on the friction disc, and a guide rail is arranged on the fixing support. A rotating main machine is arranged on the guide rail slidably, and a locking nut connected with a locking handle is arranged at one end, away from the locking disc, of the fixing shaft through an outer thread. By the ultra-light portable trestle drilling machine, the problems that the drilling angle of the anchor drilling machines in the prior art cannot be adjusted after being docked and the universality is low are solved.
