Abstract: There is provided a trammer in the present invention, comprising a panel and a handspike, with the handspike slots corresponding to the handspike located on both sides of the panel and the locating device connected with the handspike also located on the panel. The locating device comprises the locating hole at the inside bottom of the handspike, the elastic fastener corresponding to the locating hole and the handspike connector. In the present invention, the position of the handspike can be selected according to the demand of users. When the handspike need to be used, the handspike can be turned out, and the handspike and the carrying panel are localized at a certain angle via locating device for operations; when the handspike need not to be used, the handspike can be embedded in the panel to effectively decrease the space volume of the trammer and be advantageous to overlap and stack up the carrying panel of the trammer.

Abstract: A toolbox includes a cover, a body, and rotary locking devices arranged symmetrically on both sides of the toolbox which connect the body and the cover. Each rotary locking device includes an upper rabbet portion arranged on the cover of the toolbox, a lower rabbet portion arranged on the body of the toolbox, and a clasp plate connecting the upper rabbet portion and the lower rabbet portion.
