Description

technical field [0001] The present invention relates to an adjustable plunger. Background technique [0002] Most of the existing plungers are widely used for fastening common workpieces and are convenient to use. However, it has the disadvantage of poor use efficiency, and it is often necessary to control the movement of the pins in and out during use. Using the ordinary knob plunger will be very laborious and time-consuming. After the plunger pin moves in and out, it cannot be tightened in time, which will damage the plunger and the workpiece. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a convenient and adjustable plunger. [0004] The technical solution adopted by the present invention to solve the technical problem is: an adjustable plunger, including a plunger body and an outer hex nut arranged at the lower end of the plunger body, a telescopic sleeve is a...
