[0059] It should also be noted that, for ease of description, only the parts related to the invention are shown in the drawings. In the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0060] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0061] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0062] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0063] Reference Figure 1-6 The adjustable laser distance measuring device 100 includes: a laser instrument 101, a support rod 102, a fixing plate 103, a fixing ring 104, a threaded plate 105, a spring 106, abutting rod 107, a driving ring 108, and a connecting rod 109; the support rod 102 is in the shape of a round rod, and a base 110 is provided at the lower end of the support rod 102, and the upper end of the support rod 102 has a thread; the fixing plate 103 is sleeved on the support rod 102 and slides up and down on the support rod 102; the fixing ring 104 is sleeved on the support rod 102, slides up and down on the support rod 102, and is located below the fixing plate 103, and the threaded plate 105 is transversely slidably arranged on the fixing ring 104, and is threadedly connected with the threaded part of the support rod 102 to fix the fixing ring 104 on the support rod 102; the spring 106 is arranged on the threaded plate 105, and is located on the side of the threaded plate 105 away from the support rod 102.

[0064] The abutment rod 107 is laterally slidably arranged on the fixed ring 104, and the abutment rod 107 is constructed in the shape of a screw; the driving ring 108 is rotatably connected to the fixed ring 104, and is located on the outer side of the fixed ring 104, and the driving ring 108 is threadedly connected to the abutment rod 107; the connecting rod 109 is used to connect the threaded plate 105 and the abutment rod 107, and the connecting rod 109 is slidably arranged on the abutment rod 107, and the sliding direction of the connecting rod 109 is consistent with the sliding direction of the threaded plate 105, and the end of the connecting rod 109 away from the abutment rod 107 is fixed on the threaded plate 105.

[0065] When adjusting the height of the laser instrument 101, the operator rotates the fixing ring 104, driving the threaded plate 105 to rotate. The threaded plate 105 is threadedly connected to the threaded portion of the support rod 102, driving the fixing ring 104 to move up or down, changing the supporting position of the fixing plate 103, and achieving the adjustment of the height of the laser instrument 101. The self-locking property of the threaded connection facilitates the height adjustment of the laser instrument 101, and at the same time, the stepless adjustment of the height of the laser instrument 101 is achieved.

[0066] The method of rotating the fixing ring 104 is more suitable for fine-tuning in a small range. When the height of the laser instrument 101 is to be adjusted in a large range, the operator rotates the driving ring 108 to drive the abutment rod 107 to move in the direction away from the support rod 102. The support rod 102 drives the threaded plates 105 on both sides of the support rod 102 to separate from the threaded parts of the support rod 102 through the connecting rod 109, canceling the restriction of the fixing ring 104 on the up and down sliding of the support rod 102, and then directly slides the fixing ring 104 up and down to drive the fixing plate 103 to slide on the support rod 102 to quickly adjust the height of the laser instrument 101. After the laser instrument 101 is adjusted to an approximate position, the driving ring 108 is reversed to drive the abutment rod 107 to move in the direction of the support rod 102, and drive the threaded plate 105 to move in the direction of the support rod 102, so that the threaded plate 105 is meshed with the threaded part of the support rod 102 again, and then the fixing ring 104 is rotated to fine-tune the height of the laser instrument 101.

[0067] By means of the sliding connection between the connecting rod 109 and the abutting rod 107 and the setting of the spring 106, a buffer space is provided between the abutting rod 107 and the threaded plate 105 to prevent the force of the abutting rod 107 from acting directly on the threaded plate 105 and causing excessive friction between the threaded plate 105 and the support rod 102. If the friction between the threaded plate 105 and the support rod 102 is too large, the threaded plate 105 cannot rotate smoothly on the threaded part of the support rod 102.

[0068] The fixing ring 104 is composed of a first half ring 104a and a second half ring 104b, which are symmetrically arranged. The second half ring 104b is fixed to the first half ring 104a by bolts and nuts, and the support rod 102 is clamped between the first half ring 104a and the second half ring 104b. A first sliding groove 104c for radial sliding of the threaded plate 105 and the support rod 102 is provided on the first half ring 104a and the second half ring 104b on one side close to the support rod 102. The threaded plates 105 are located on both sides of the support rod 102 and are threadedly connected to the threaded parts on the support rod 102.

[0069] The arrangement of the fixing ring 104 being split into the first half ring 104 a and the second half ring 104 b is conducive to conveniently and quickly assembling the threaded plate 105 , the abutting rod 107 , the connecting rod 109 and the spring 106 on the fixing ring 104 .

[0070] A first limiting groove 105a for the spring 106 to be embedded is provided on one surface of the threaded plate 105 close to the abutting rod 107, a second limiting groove 107a for the spring 106 to be embedded is provided on one surface of the abutting rod 107 close to the threaded plate 105, and a second sliding groove 107b is provided on the bottom surface of the second limiting groove 107a, and the connecting rod 109 slides in the second sliding groove 107b.

[0071] The connecting rod 109 is composed of a sliding portion 109a and a connecting portion 109b. The sliding portion 109a is constructed in a disc shape and is slidably arranged in the second slide groove 107b. The sliding portion 109a of the connecting portion 109b is constructed in a round rod shape and is integrally formed on the side of the sliding portion 109a close to the threaded plate 105. The diameter of the sliding portion 109a is larger than the diameter of the sliding portion 109a of the connecting portion 109b. At the notch of the second slide groove 107b, a baffle 112 is fixed to limit the sliding portion 109a from detaching from the second slide groove 107b.

[0072] The threaded portion on the support rod 102 is threadedly connected to a limiting ring 111 . The limiting ring 111 is located above the fixing plate 103 and is used to limit the fixing plate 103 from upwardly separating from the support rod 102 and to resist the fixing plate 103 .

[0073] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
