Bu buluş, İstem 1 `in giriş kısmına göre bir elektrikli alet ile ilgilidir. Bu gibi bir elektrikli alet "Triton Dual Mode Precision Plunge Router TRA001", 21st March 2012, (XP055356831) belgesinde açıklanmıştır. Daha özel olarak (illa özel olması şart değildir) buluş, yaygın olarak freze olarak bilinen ve üzerinde çalışılan parça üzerinde, dönen bir kesme takımı ile çalışma yapabilme özelliğine sahip elektrikli el aletleri ile ilgilidir. A power tool which includes a housing (6) and a base (8), the housing (6) mounted to be moveable with respect to, and spaced from, the base (8). The base and housing are connected by at least first and second extendable assemblies (10, 12), at least one of the assemblies (12) including biasing means (48) located so as to bias the housing away from the base. In one embodiment this extendable assembly (12) is provided with a control portion (42) which can be moved, while located with the said extendable assembly, from a first position in which the biasing means is engaged to provide the biasing force (figure 2b) and a second position in which the biasing means is released from providing the biasing force (figure 2a). In an alternative embodiment the power tool includes a switch which allows the switching on and off of the motor and control of whether the cutting tool is capable of being rotated or not, a cover is provided for the switch such that that the motor cannot be accidentally activated once switched off and when the switch is moved to the on position the cover is held back by the switch, against a biasing force, said cover further includes a safety stop portion which limits the progress of at least one of the extendable assemblies when the cover is held by the switch in the on position and wherein the safety stop portion is formed to contact with the said guide arm of the said at least one extendable assembly to a sufficient extent to prevent further movement of the extendable assembly when the switch is in the on position and to allow a biasing means to be included in the said extendable assembly. In another embodiment a height adjustment mechanism is provided which includes a sprocket which engages teeth formed as a rack along a guide arm of at least one of the extendable assemblies and wherein the movement of the housing with respect to the base can be user selected between a plunge movement in which the user exerts the movement force to move the housing towards the base, or via the height adjustment mechanism operated by hand or via powered drive connected thereto. In another embodiment the power tool includes safety stop portions to prevent movement of the tool holder while cutting tool changing is being performed.
