[0002] The power supplies in the related art (especially the portable power supplies for outdoor use and with high power) have high energy requirements, which requires an increase in the number of battery cells in the power supply, resulting in an increase in the overall mass. The increase in mass usually requires that the tensile strength, bending strength and other strengths of the product be enhanced. At present, this type of power supply usually requires an additional handle on the outer shell. The handle generally needs to use a coating technology (such as wrapping the plastic part with hardware) and a reinforced structure (such as increasing the material thickness through gas-assisted injection molding) to strengthen its connection with the outer shell. In addition, the power supply usually needs to be strengthened by laying precision sheet metal parts on the front and back or left and right sides of the whole machine, or by directly increasing the wall thickness. That is, no matter which reinforcement method is used, the power supply will have problems such as complex process, high manufacturing cost, many parts and components, and difficult assembly.

Next, assemble the first frame 231, which has the first electrode sheet 40 pre-installed, onto the second frame 232, inserting each battery cell 32 into the corresponding first retaining groove 2313. Finally, push the first frame 231 toward the second frame 232 until the first and second frames 231 and 232 are joined. Then, install the first conductive connecting piece 50 on the first accommodating portion 2311, and the second conductive connecting piece 70 on the second accommodating portion 2321.

[0063] The first pressing piece 241 is pressed onto the first extending protrusion 2312 and the first receiving portion 2311. The second pressing piece 242 is pressed onto the side of the second extending protrusion 2322 opposite the first extending protrusion 2312. A first screw assembly is used to connect and secure the second pressing piece 242, the first extending protrusion 2312, the second extending protrusion 2322, and the first pressing piece 241. A second screw assembly is used to penetrate the first connecting hole 221 and the third through hole 2422 to securely connect the fixing frame 23 to the column 22.

[0064] The fixing frame 23 connected to the column 22 is fixed on the bracket on which the holding bracket 25 is installed. The first columnar body 22a of the column 22 can be inserted along the insertion channel 2524 of the holding bracket 25, and then the bracket 21 and the column 22 are connected and fixed by setting a third screw assembly. Specifically, the screw of the third screw assembly can pass through the second mounting hole 2113 of the bracket 21 to be connected to the second connection hole 222 of the column 22.

[0065] The frame assembly loaded with the battery module 30 and equipped with the gripping bracket 25 is assembled together with the first shell 11 and the second shell 12. The first shell 11 can be connected and fixed to the column 22 using a fourth screw assembly. The screw of the fourth screw assembly can be inserted from the first shell 11 into the third connection hole 223 of the column 22 and screwed to the third connection hole 223. The first handle 252 can be assembled and fixed with the second handle and fixed by screws. The second shell 12 is then connected and fixed to the column 22 using a fifth screw assembly. The screw of the fifth screw assembly can be inserted from the second shell 12 and passed through the fourth through hole 2525 to connect and fix to the fourth connection hole 224 on the column 22.
