[0002] A metal puller is a tool used for inserting and removing printed circuit boards. It is connected to a fixed block by a cylindrical pin, and the puller uses the cylindrical pin as a pivot to perform the pulling function.

[0003] In existing metal pullers, the operator holds the handles and controls the opening and closing of the two handles, which in turn opens and closes the two puller heads. The puller heads then pull objects, thus fulfilling the function of the metal puller. However, the ends of the puller heads are usually wide, making them only suitable for pulling objects of a certain size. When pulling relatively narrow objects, the operation becomes relatively cumbersome and inconvenient. Furthermore, the operation of the metal puller requires complete manual control of the opening and closing of the puller heads, which is quite laborious. Utility Model Content
