Rock slice grinding handheld device

The invention provides a rock slice grinding handheld device. The rock slice grinding handheld device comprises a door-shaped handheld structure formed by connecting a transverse telescopic loop bar to two upright poles, wherein the bottom ends of the two upright poles are respectively connected to two clamping cavities; each clamping cavity is an inverted rectangular bucket body; the openings ofthe two clamping cavities are opposite; the two clamping cavities are used for clamping a glass slide; and a telescopic screw rod is further connected between the two upright poles and is used for increasing the clamping force of the glass slide. The rock slice grinding handheld device is simple in structure, effectively fixes the glass slide, improves the working efficiency, and avoids the directcontact with the glass slide to ensure personal safety. 一种岩石薄片磨制手持器，包括由横向的伸缩套杆连接两立杆构成的门形手持结构，两立杆底端分别连接一个夹腔，夹腔呈倒置的矩形斗状体，两夹腔开口相对，用于夹持载玻片；两立杆之间还连接有伸缩丝杆，用于增大载玻片的夹持力；本发明结构简单，有效固定载玻片，提高工作效率，并且避免直接接触载玻片，保证人身安全。
