The invention provides a straight rod drawing device. The straight rod drawing device comprises a pressing rod, a pressing rod support and a clamping part; the pressing rod is hinged on the pressing rod support through a rotating shaft; the clamping part is fixed to the end part of the pressing rod; the clamping part consists of two S-shaped clamping pieces which are hinged together; each S-shapedclamping piece is formed by connecting two S-core steel bars or steel plates through upright posts, wherein the S-core steel bars or steel plates are arranged in an orthographic projection shape; themiddle parts of the two S-shaped clamping pieces are hinged by using a rotating shaft; each S-shaped clamping piece consists of an upper straight section and a lower C-shaped section which are hinged; the upper end of the upper straight section of each of the two S-shaped clamping piece is provided with a sleeve; each sleeve is connected to the pressing rod by a flexible part; the other ends of the two S-shaped clamping pieces are each fixedly provided with a clamping block; the opposite sides of the two clamping blocks are correspondingly provided with clamping grooves; and each clamping groove is internally provided with a skid-proof structure. The drawing device can easily realize the drawing operation of a straight rod by adopting the lever principle, and has outstanding practicability.
一种直杆抽拉装置，包括压杆、压杆支撑和夹持部，压杆通过转轴铰接在压杆支撑上，夹持部固定在压杆的端部，夹持部由两个铰接在一起的S形夹持件组成，S形夹持件由两个呈正投影状布置的两个S心钢条或钢板采用立柱进行连接而成，两S形夹持件的中部采用转轴进行铰接，形夹持件由铰接的上部笔直段和下部C形段组成，所述两S形夹持件上部笔直段的上端设置有套筒，套筒通过柔性件连接在压杆上，两S形夹持件的另一端分别固定有一个夹块，两夹块的相向侧对应设置有夹持槽，夹持槽内设置有防滑结构。该抽拉装置采用杠杆原理可轻松实现对直杆的抽拉操作，具有突出的实用性。
