Meanwhile, the display screen 4 is arranged on the shell 1, so that the number measured by the laser lens 2 can be fed back, and the reading by a user is facilitated. Set up handle 5 in one side of casing 1, and this handle 5 is made by the nylon material to can make user's hand pass handle 5 and hold whole casing 1, make things convenient for the handheld measurement of user.

Be provided with slide 10 in casing 1, be provided with slide 10 sliding connection's ball 11 in slide 10, make ball 11 constantly roll in slide 10, thereby ball 11 can roll to one side of downward sloping when casing 1 takes place to incline, well department in slide 10 is provided with electric piece 12, thereby need when ball 11 contacts electric piece 12, just can be for laser lens 2 circular telegram, thereby it surveys to carry out the range, consequently need guarantee that the horizontality of casing 1 just can measure, thereby great improvement measuring accuracy, also can effectual detection casing 1 be in the state of an incline. The slide way 10 is arc-shaped, so that when the ball 11 rolls in the slide way 10, once the shell 1 is in a horizontal state, the ball 11 automatically rolls to the center of the slide way 10 and contacts the first electric sheet 12, wherein the first electric sheet 12 is a touch switch, the laser lens 2 can be electrified only by contacting the first electric sheet 12 with the ball 11 positioned above the first electric sheet 12, and when the shell 1 is not in a balanced state, the ball 11 can automatically roll to one side inclined downwards, namely the ball 11 is not contacted with the first electric sheet 12, so that the laser lens 2 is not electrified.

An angle scale 7 is further arranged in the shell 1, degrees marked on the angle scale 7 are provided, meanwhile, a pointer 8 is pivoted in the angle scale 7, and the inclination angle of the shell 1 can be displayed through the pointer 8. The ball 11 is made by magnet, 8's of pointer front end is provided with magnet simultaneously, thereby can attract pointer 8 through ball 11, can take pointer 8 at 7 rotations of angle scale when ball 11 slides in slide 10 promptly, thereby after 1 rotation certain angle of casing, ball 11 rolls a certain distance back in slide 10, attract pointer 8 simultaneously and be close to ball 11, the numerical value of reading out is the angle of 1 slope of casing this moment on angle scale 7, can make the user know 1 turned angle of casing, in order to make things convenient for the back to correct data and casing 1. The observation plate 6 is arranged outside the slide way 10, the observation plate 6 is connected with the shell 1, and the observation plate 6 is a transparent plate, so that a user can observe the position of the pointer 8 on the angle scale 7, and can effectively know the convenient adjustment of the inclined angle of the shell 1.

The observation plate 6 is provided with a lower pressure rod 14, the lower pressure rod 14 penetrates through the observation plate 6 and is connected with the observation plate 6 in a front-back sliding mode, so that the lower pressure rod 14 can slide on the observation plate 6 in the front-back direction, meanwhile, a second electric sheet 13 is arranged in the shell 1, the second electric sheet 13 corresponds to the bottom of the lower pressure rod 14, the second electric sheet 13 and the first electric sheet 12 are both touch switches, and the second electric sheet 13 needs to be in contact with the bottom of the lower pressure rod 14 to be electrified. Therefore, when the lower pressing rod 14 is pushed into the shell 1, the bottom of the lower pressing rod 14 is in contact with the second electric sheet 13, the laser lens 2 can be electrified, when a certain angle is needed for measuring an object, the lower pressing rod 14 can be in contact with the second electric sheet 13, the laser lens 2 can be electrified for measuring, and the rotating direction of the shell 1 can be determined according to the rolling position of the spherical ball 11 in the slide way 10 and the degree indicated by the pointer 8. A first spring 15 is arranged between the lower pressing rod 14 and the observation plate 6, the bottom of the lower pressing rod 14 is not contacted with a second electric sheet 13 through the elastic force of the first spring 15, horizontal sliding grooves 16 are respectively formed in two sides of the lower pressing rod 14, a hemispherical block 18 in sliding connection with the sliding grooves 16 is arranged in the sliding grooves 16, so that the hemispherical block 18 can slide in the sliding grooves 16, meanwhile, a second spring 17 is arranged on the hemispherical block 18 and the lower pressing rod 14, and the hemisphere is exposed out of the lower pressing rod 14 through the elastic force of the second spring 17. When the hemisphere block 18 is positioned in the observation plate 6, the hemisphere block 18 retracts into the lower pressure rod 14, the lower pressure rod 14 slides towards the shell 1, so that when the hemisphere block 18 is positioned between the observation plate 6 and the shell 1, the hemisphere block 18 pops up and is clamped on the rear side of the observation plate 6, and meanwhile the bottom of the lower pressure rod 14 contacts the second electric sheet 13, so that the laser lens 2 is electrified; when horizontal use is required, the down-pressure lever 14 is pulled outward so that the hemispherical block 18 is retracted into the down-pressure lever 14 and the hemispherical block 18 is located in the viewing plate 6 so that the down-pressure lever 14 can slide inward of the housing 1.

The working principle is as follows: when the laser distance measuring device used horizontally is used, when the shell 1 needs to be kept in a horizontal state, the bottom of the lower pressure rod 14 is not in contact with the second electric sheet 13, when the shell 1 is in the horizontal state, the round ball 11 is in contact with the first electric sheet 12 to electrify the laser lens 2, when the shell 1 inclines, the round ball 11 rolls in the slide way 10, the round ball 11 is not in contact with the first electric sheet 12, the laser lens 2 is not electrified, and meanwhile, when the round ball 11 rolls in the slide way 10, the pointer 8 is attracted to rotate in the dial, so that the inclined angle of the shell 1 can be obtained. When the inclined laser range finder is not needed to be used, the lower pressing rod 14 slides towards the shell 1, the hemispherical block 18 is clamped at the rear side of the observation plate 6, and meanwhile the bottom of the lower pressing rod 14 is in contact with the second electric sheet 13, so that the laser lens 2 is electrified, and the inclined laser range finder is used in an inclined mode.
