Burglarproof lamp

A burglarproof lamp comprising:

• a lamp holder part;
• a light emitting part;
• a base via which the lamp holder part and the light emitting part are connected;
• and
• two power lines, wherein
• the lamp holder part comprises a lamp holder shell, a center contact screw, a center contact insulation fixing base, a center contact insulation fixing sheet, and conductive post, a center conductive shaft, a spring, at least one positioning post, a connection part fixing base, a conductive clamping ring, and a conductive fixing ring,
• the center contact bolt successively passes through the centre contact insulation fixing base, the lamp holder shell and the center contact insulation fixing sheet so as to be fixedly connected with the conductive post for electric conduction,
• a containing activity where the spring and the center conductive shaft are successively located and a boss are provided in the lower part of the connection part fixing base,
• the positioning post is embedded in the bottom of the connection part fixing base,
• at least one positioning hole adapted to the positioning post in size and position is provided on the center contact insulation fixing sheet,
• the connection part fixing base together with the positioning post, the spring and the center conductive shaft are placed above the center contact insulation fixing sheet within the lamp holder shell,
• the conductive clamping ring is sleeved on the outer wall of the connection part fixing base,
• the conductive fixing ring is sleeved on the connection part fixing base and fixedly connected with the lamp holder shell for electric conduction and limiting the connection part fixing base axially via the boss,
• the conductive clamping ring is in conductive contact with the lamp holder shell,
• the center conductive shaft is in conductive contact with the conductive post,
• the connection part fixing base is able to drive the positioning post to rotate between the lamp holder shell and the conductive fixing ring and move axially,
• the connection part fixing base is able to set a circumferential limit with the center contact insulation fixing sheet by inserting the positioning post into the positioning hole when the positioning post rotates to a position corresponding to the positioning hole, and
• the two power lines are conductively connected with the conductive clamping ring and the center conductive shaft respectively.
