竖向钻孔的支撑装置
摘要：
本实用新型提出了一种竖向钻孔的支撑装置，包括放置电钻的固定装置和底座，所述底座上设有一个升降装置，升降装置一端连接到底座下端；底座上设有移动装置，以及与移动装置配合的移动限位装置。本实用新型的装置底座附带移动滑轮，用以调节钻孔位置，位置调节完毕后关闭移动滑轮的移动限位装置，以将装置固定在某一位置。转动升降摇杆，摇杆带动传动齿轮盘，传动齿轮盘内的齿轮通过咬合竖直卡齿以升降卡尺，从而带动钻头上升或下降，以控制钻头对准所需钻孔处，同时可从读数孔读取卡尺上的数值。最后，开动电钻电源，摇动摇杆，通过读数孔，观察并控制所需钻孔深度，达到精确的钻取深度。
摘要（英）：

The utility model provides a supporting device of a vertical drill hole. The supporting device comprises a fixing device and a base, wherein the fixing device and the base are used for placing an electric drill. A lifting device is arranged on the base, and one end of the lifting device is connected to the lower end of the base. A moving device and a moving limiting device matched with the moving device are arranged on the base. A moving pulley is additionally arranged on the base of the supporting device and used for adjusting the position of the drill hole, and after position adjustment is finished, the moving limiting device of the moving pulley is switched off so as to fix the device to a certain position. A lifting rocker is rotated and drives a transmission gear plate. A gear in the transmission gear plate lifts a caliper by being meshed with a vertical latch so as to drive a drill bit to ascend or descend, and therefore the drill bit is controlled to be aligned at a position needing drilling. Meanwhile, the numerical value on the caliper can be read from a reading hole. Finally, an electric drill power supply is turned on, the rocker is rocked, the needed depth of the drill hole is observed and controlled through the reading hole, and the accurate drilling depth can be reached.
