Detailed Description

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the concepts underlying the described embodiments. It will be apparent, however, to one skilled in the art, that the described embodiments may be practiced without some or all of these specific details. In other instances, well known process steps have not been described in detail.

As shown in fig. 1, 2 and 3, the extended police shield comprises a mounting plate 1, sliding plates 2 are slidably disposed at upper and lower ends of the inside of the mounting plate 1, a driving mechanism 3 is fixedly disposed at the middle end of the right side of the inside of the mounting plate 1, a limiting plate 4 is fixedly disposed at the middle end of the right side of the inside of the mounting plate 1, a linkage mechanism 5 is fixedly disposed at the middle end of the inside of the mounting plate 1, a control mechanism 6 is fixedly disposed at the upper side of the front end of the outside of the mounting plate 1, a lithium battery 7 is embedded and tightly assembled at the right side of the front end of the mounting plate 1, the driving mechanism 3 can control the linkage mechanism 5 to drive the sliding plates 2 to be in an unfolded or stored state, so that the whole police shield can be unfolded or stored and displaced, the control mechanism 6 can activate the opening and closing of the driving mechanism 3, the driving mechanism 3 is composed of a motor 8, a rotating shaft 9 and a driving bevel gear 10, and a motor 8 is fixedly disposed at the middle end of the right side of the inside of the mounting plate 1, motor 8 left side the pivot 9 has set firmly, pivot 9 run through in limiting plate 4, pivot 9 left side drive awl tooth 10 has set firmly, link gear 5 constitute by backup pad 11, lead screw 12 and linkage awl tooth 13, 1 inside middle-end of mounting panel set firmly
