The elastic band 2 is fixed on the surface of the battery box 1 by gluing.

The battery box 1 is provided with a fastener for passing the elastic band 2, and the elastic band passes through the fastener to be connected with the battery box 1.

The length of the elastic band 2 is adjustable.

The spherical hinge structure 7 consists of a bulb at the tail part of the lamp holder and a spherical cavity at the head part of the hollow connecting rod, and the head part of the hollow connecting rod is provided with a U-shaped notch for the pitching rotation of the lamp holder connecting rod; the ball head at the tail part of the lamp holder 4 is also provided with a notch so as to facilitate the extension and contraction of a power supply lead.

And a light-gathering cover 8 is additionally arranged at the front part of the lamp cap.

The utility model has the advantages that:

the utility model discloses an integrated design very conveniently carries. The lamp holder can rotate 180 degrees, can be straightened and used as a flashlight, and can be conveniently rotated to a right angle to be used as a head lamp.

The utility model discloses a lamp holder can guarantee to be coaxial basically with the field of vision, and the diameter of lamp holder is also relatively small and exquisite, does not shelter from the field of vision like this.

The utility model discloses an elastic cord has the advantage of accomodating very convenience as wearing the accessory.

The utility model discloses a lithium cell power supply has small, longe-lived, light in weight's advantage, and the whole headlight is folded up the back and is only slightly greater than the volume of battery case.
