In the figure: the luminous watch comprises a shell 1, a protective cover 2, an elastic wrist strap 3, a dial 4, a luminous pointer 5, a correcting knob 6, a level 7, a rubber ring 8, a fixture block 9, a clamping groove 10, a supporting mechanism 11, a sliding groove 111, a bidirectional screw 112, a sliding block 113, a first support rod 114, a second support rod 115 and an adjusting knob 116.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Example 1:

referring to fig. 1-2, a convenient hydrogeological compass comprises a shell 1, wherein a protective cover 2 is hinged to the outer side of the shell 1, and the protective cover 2 is used for protecting a dial 4; the bottom of the shell 1 is fixedly provided with an elastic wrist strap 3, and the elastic wrist strap 3 is used for carrying the whole compass; a dial 4 is fixedly arranged on the inner side of the shell 1, a noctilucent pointer 5 is rotatably arranged at the center position of the dial 4, and the noctilucent pointer 5 can realize indication under the condition of insufficient light; a corresponding correcting knob 6 is rotatably arranged on the outer side of the shell 1, and the correcting knob 6 is used for adjusting the noctilucent pointer 5; the middle part of the inner side of the shell 1 is fixedly provided with a corresponding level 7, and the inner side of the protective cover 2 is fixedly provided with a rubber ring 8 matched with the dial 4; the rubber ring 8 can protect the dial 4, so that the dial 4 can be prevented from being abraded in the transportation process; a clamping block 9 is fixedly arranged at one end of the bottom of the protective cover 2, a corresponding clamping groove 10 is formed at one end of the inner side of the shell 1, and the clamping block 9 can be matched with the clamping groove 10.
