The flashlight comprises a flashlight body 1, a connecting groove 11, a rotary table 111, a return spring 112, a limiting flange 113, an internal thread 114, a limiting boss 12, a telescopic rod 2, a connecting rod 21, a knurling 211, an external thread 212 and a ball 3.
Detailed Description
The invention will be further described with reference to the following specific embodiments:
referring to fig. 1 to 3, a portable knock device with an illumination function includes a flashlight body 1, a telescopic rod 2, and a ball 3, and is characterized in that: the telescopic link 2 includes the connecting rod 21 that the multistage set gradually from lower to upper, and multistage connecting rod 21 cavity is so that the connecting rod 21 that is located the upside folds to the connecting rod 21 that is located the downside in downwards, and the bottom lateral wall of every section connecting rod 21 is formed with annular knurl 211, and every section connecting rod 21's internal diameter narrows down so that the annular knurl 211 that is located the connecting rod 21 of upside upwards removes and forms interference fit with the connecting rod 21 inside wall of downside by lower supreme gradually, is located connecting rod 21 top connection ball 3 of the top.
The top surface of the flashlight body 1 is provided with a connecting groove 11, the connecting groove 11 is in threaded connection with the connecting rod 21 located at the lowest side, a turntable 111 is arranged in the connecting groove 11, the turntable 111 rotates in the connecting groove 11, and a return spring 112 is connected between the turntable 111 and the connecting rod 21 located at the lowest side.
A limit flange 113 is arranged in the connecting groove 11, the limit flange 113 is located right above the rotary disc 111 and used for limiting the rotary disc 111 to upwards withdraw from the connecting groove 11, an internal thread 114 is formed in the connecting groove 11, an external thread 212 is formed on the outer side wall of the bottom end of the connecting rod 21 located at the lowest side and used for being in threaded connection with the internal thread 114 of the connecting groove 11, a limit boss 12 is formed on the top surface of the flashlight main body 1, and the telescopic rod 2 penetrates through the limit boss 12 and is downwards connected with the return spring 112.
