Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Referring to fig. 1 to 3, as shown in fig. 1 to 3, a tool for internal precracking of a housing, comprises: the tool comprises a tool handle 1, a tool bit fixing seat 3 arranged at the tail end of the tool handle 1 and a tool bit 2 arranged on the tool bit fixing seat 3;

a fastening mechanism is arranged between the tool bit 2 and the tool bit fixing seat 3.

It should be noted that the main invention of the present invention is to control the groove depth by using the inclined plane, to position by using the positioning pin, and to fix by using the screw.

This scheme mainly used shell product inner chamber straight line of putting out a fire is crackle's processing in advance, once only accomplishes the straight line that a angle was injectd and crack processing in advance at the inner chamber of casing through the tool bit, then through the distance between regulation tool bit and the casing inner chamber, realizes the regulation of presplitting the line depth.
