摘要： A soldering iron can be constructed using a heating element structure or first part connected to a handle structure or second part through the use of connectors on these parts which are adapted to be secured together through the use of a rotary or twisting type motion. The handle structure includes a spring biased sleeve which projects from it toward the heating element structure. The heating element structure includes a metal flange which is resiliently engaged by the sleeve when the parts are connected together. This flange in effect forms a part of a tubular, metal housing used to connect a body disposed in proximity to the heating element so as to conduct heat away from the heating element and the connector on the heating element structure. The housing serves to protect the heating element structure against physical damage and is grounded through the flange and the sleeve to an appropriate grounding wire leading from the handle structure.

摘要： A locking accessory bracket for use with an accessory standard. A locking accessory bracket that may be used with an accessory standard that essentially comprises a flat, straight elongated body portion having a multiplicity of identical, spatially positioned, upwardly projecting, L-shaped hook members located on either side thereof. The locking accessory bracket comprises a flat mounting plate and a hook plate made integral therewith. The hook plate has a plurality of identical, spatially positioned, downwardly projecting, L-shaped hook members, for detachable engagement with desired ones of the multiplicity of upwardly projecting hook members of the accessory standard. The improvement comprises a locking member that is rotatably mounted at a topmost portion of the hook plate. When downwardly projecting hook members of the hook plate are detachably engaged with corresponding ones of the multiplicity of upwardly projecting hook members of the accessory standard, the locking member abuts a bottom portion of an upwardly projecting hook member immediately adjacent to a topmost downwardly projecting hook member of the hook plate. Thus, the position of the locking member substantially inhibits removal of the mounting plate from the accessory standard.
摘要翻译：用于附件标准的锁定附件支架。可与附件标准一起使用的锁定附件支架，其基本上包括平坦的直的细长主体部分，其具有位于其任一侧上的多个相同的空间定位的向上突出的L形钩构件。锁定附件托架包括平板安装板和与其成一体的钩板。钩板具有多个相同的，空间上定位的向下突出的L形钩构件，用于与附件标准的多个向上突出的钩构件中的期望的可拆卸接合。该改进包括可旋转地安装在钩板的最上部的锁定构件。当钩板的向下突出的钩构件与附件标准的多个向上突出的钩构件中的相应的钩构件可拆卸地接合时，锁定构件邻接最靠近的向下突出的钩构件的向上突出的钩构件的底部的钩板。因此，锁定构件的位置基本上阻止安装板从附件标准的移除。
