Anti-clamping type throwing and fishing device

The invention relates to an anti-clamping type throwing and fishing device. The pipe wrench mainly solves the problems that a wrench head of the pipe wrench is prone to falling off and operation is inconvenient. The device is characterized in that the upper end of an upper main body (3) is connected with a turning joint, the side wall of the upper main body (3) is connected with a support arm (5), the end part of the support arm (5) is connected with a fishing head (16), the bottom of the upper main body (3) is connected with a lower main body (10) through a connecting rod (6), and the bottom of the lower main body (10) is connected with a combined scraper (11). The anti-blocking throwing and fishing device can be normally lifted in a well with serious oil pipe scaling and a well with deflection or slight tubular column deformation, and can be automatically released when blocked, so that the number of operation wells is reduced, and the testing efficiency is improved. 本发明涉及一种防卡式投捞器。主要解决管钳的钳头易脱落、操作不方便的问题。其特征在于
