The distance-measuring telescope module 20 is used to provide laser distance-measuring and telescope functions, and the specific structure thereof is not limited, for example, the distance-measuring telescope module 20 may be a monocular type or a binocular type. Specifically, the distance-measuring telescope module 20 is of a monocular type, and as shown in fig. 6 and 7, one end of the distance-measuring telescope module 20 is provided with an eyepiece portion 210, and the other end thereof is provided with a signal-emitting lens 220 and a signal-receiving lens 230 which are arranged side by side in an up-and-down manner. The optical axis direction of the emission signal lens 220 is consistent with that of the ocular part 210, and the emission signal lens 220 and the ocular part 210 are arranged at two opposite ends of a lens barrel 201 during specific arrangement, and the two are matched to realize a telescopic function. The receive lens 230 is located below the transmit lens 220. It should be noted that the vertical arrangement is only used for explaining the relative positions of the signal emitting lens 220 and the signal receiving lens 230, and here, the signal receiving lens 23 is located below the signal emitting lens 220, which means that the signal receiving lens 23 is located below the signal emitting lens 220 in the vertical direction when the laser range telescope 100 is in normal use.

A laser emitting module (not shown) is also arranged in the lens barrel 201, and an emitting adjusting module 240 is arranged below the lens barrel 201; an absorption adjustment module 250 is further disposed below the lens barrel 201 on a side of the signal receiving lens 230 close to the eyepiece portion 210.

Preferably, the first mounting portion 131 is a protrusion protruding from the inner wall of the opening 131, and the protrusion is provided with a through hole 1311 along the axis; the second mounting portion 202 is a threaded hole. Before assembling the front cover 30, the first and second mounting

portions

131 and 202 are coupled by the fastener 200. The fastener 200 includes a screw or bolt. In addition, the second mounting portion 202 may be a through hole, and in this case, a taper pin may be used as a fastener to fasten the first mounting portion 131 and the second mounting portion 202. Specifically, the first mounting portion 131 is provided at two positions, which are uniformly distributed in the circumferential direction of the opening 130. The second mount portion 202 is correspondingly disposed at two positions between the signal emitting lens 220 and the signal receiving lens 230, and the two second mount portions 20 are disposed at a left-right interval.

In some embodiments, as shown in fig. 6 and 7, the laser range telescope 100 further comprises a connecting rod 50. The connecting rod 50 is provided with two positions along the axial direction of the lens barrel 201, and the two positions are respectively positioned at two sides of the distance measuring telescope module 20. One end of the connecting rod 50 is connected to the front end of the distance-measuring telescope module 20 by a screw, and the other end of the connecting rod 50 is used to be fixedly connected to the rear end cover 40. By the above means, the rear end cap 40 can be assembled with the distance measuring telescope module 20 in advance as a module, and then the module is inserted into the opening 130 of the housing 10, thereby further improving the convenience of assembly. The connecting rod 50 is made of metal material and has better strength. Alternatively, the rear end cap 40 may be separately assembled to the rear end surface 120 of the housing 10.
