Embodiment Construction

[0020] figure 1 The jigsaw 10 shown is one embodiment of the present invention. The jigsaw 10 includes a casing 1 , a motor 2 installed in the casing 1 and a transmission system 3 , and a chuck 4 connects the saw blade 9 with the transmission system 3 . Therefore, the motor 2 rotates to drive the transmission system 3 to move, and then drives the saw blade 9 to perform reciprocating cutting motion. This structure is relatively familiar to those skilled in the art, and will not be described in detail here. It should be noted that the casing 1 refers to the casing of the jigsaw 10 , which is used to accommodate the motor 2 , the transmission system 3 and other components. The casing 1 can be integrated, separated or spliced.

[0021] Depend on figure 1 It can be seen that there is a temperature warning device 5 on the chuck 4 of the jigsaw 10, and the temperature warning device 10 is also installed on the saw blade 9. Wherein the temperature warning device 10 on the saw bla...

Abstract

The invention relates to a power tool and a work head of the power tool, wherein the power tool comprises a casing, a power source, a drive system installed in the casing, a connecting device for connecting the work head with the drive system, and a temperature warning device installed on the part of the power tool which is easy to heat; and the work head of the power tool comprises the temperature warning device. The temperature changes in each part of the power tool and the work head thereof are reflected by the temperature warning device so as to intuitively warn an operator of the temperature in a corresponding part, improve the safety in utilization of the power tool and prolong the service life of the power tool and the work head thereof.

Description

technical field [0001] The invention relates to a power tool capable of processing objects, and also relates to a working head assembled on the power tool. Background technique [0002] Power tools are one of the more common types of power tools. Electric tools generally include a motor. During use, the motor rotates and drives a transmission mechanism composed of a set of moving parts. The transmission mechanism then drives the working head to perform corresponding movements, so that the working head performs various operations on the target object. [0003] During the use of the power tool, various parts of the body will heat up with the continuous movement of the moving parts in the body. The most important heat source is usually the motor and the transmission mechanism. Although most power tools have ventilation and heat dissipation systems, the heat generated inside the power tool cannot be completely dissipated during continuous use, and most of it is accumulated in ...
