Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, in an embodiment of the present utility model, a positioning screw for a mobile phone motherboard includes a screw body 1, wherein the screw body 1 is sleeved in an upper clamping spring coil 5 and is in threaded connection with a lower clamping spring coil 3; and a spring 4 is arranged between the lower clamping spring ring 3 and the upper clamping spring ring 5.

Through adopting above-mentioned technical scheme, lower jump ring circle 5 bonds or welds with the cell-phone medium plate and be connected, utilizes the screw body to pass cell-phone mainboard and 3 thread tightening of lower jump ring circle afterwards, under the top of spring 4 moves, goes up the jump ring circle 5 and has an ascending top power to the cell-phone mainboard to provide a support for the cell-phone mainboard, consequently just need not to change new cell-phone medium plate, very big cost of maintenance who has saved the cell-phone.

In this embodiment, the top of the screw body 1 is provided with a nut, a cross dismounting groove is formed in the nut, and dismounting holes 2 are formed in two sides of the nut.

As a further explanation, after some screws are long in time, a snap phenomenon occurs between the dismounting groove at the top of the screw and the screwdriver, so that the dismounting groove is damaged, and the screw cannot be dismounted normally; therefore, the dismounting holes 2 are formed in the two sides of the screw, and when the dismounting groove at the top of the screw is damaged, the dismounting efficiency of the screw is improved through the dismounting of the clamp spring pliers.
