[0010] Furthermore, the material of the sleeve is plastic.

[0011] The utility model has the following beneficial technical effects:

[0012] 1. The utility model adjusts the height of the laser transmitter through a casing, uses the laser transmitter to indicate the construction height, and reduces the error caused by human factors.

[0013] 2. When using the utility model, the height of the laser transmitter can be determined by observing the scale, which is convenient for subsequent accurate construction and for unifying the heights of multiple devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-Figure 3As shown, the device for indicating the height of masonry mortar joints of this embodiment includes a sleeve 1, a first knob 2, a second knob 3 and a laser emitter 4. The sleeve 1 includes a lower section 11, a middle section 12 and an upper section 13. The outer wall of the middle section 12 is slidably connected to the inner cavity of the lower section 11, and the outer wall of the upper section 13 is slidably connected to the inner cavity of the middle section 12. The first knob 2 penetrates the side wall of the lower section 11 and is threadedly connected to the thread groove 16 opened on the side wall of the middle section 12. Another first knob 2 penetrates the side wall of the middle section 12 and is threadedly connected to the thread groove 16 opened on the side wall of the upper section 13; one end of the second knob 3 penetrates the top of the upper section 13 and is fixed to the laser emitter 4.

[0022] The sleeve 1, as the basic structure of the entire component, consists of three sections: the lower section 11, the middle section 12 and the upper section 13. It adopts a sliding connection design to ensure the flexibility and stability of the component in different application scenarios; the first knob 2 not only enhances the stability of the middle section 12 and the upper section 13, but also provides users with a convenient adjustment method to adapt to different operating requirements; the second knob 3 ensures the accuracy of the position adjustment of the laser emitter 4, thereby ensuring the accuracy of the laser emission. The laser emitter 4, as the core part of the component, has stable and reliable performance and can maintain excellent laser emission effects in a variety of environments. Through the precise control of the second knob 3, the laser emitter 4 can achieve highly precise adjustments in angle and position to meet the needs of various application scenarios.

[0023] Furthermore, a scale 14 is marked on the same side wall of the lower section 11 , the middle section 12 and the upper section 13 .

[0024] Determining the height of the laser emitter 4 by observing the scale 14 is convenient for subsequent accurate construction and for unifying the heights of multiple devices.

[0025] Furthermore, a support leg 15 is fixed to the bottom of the lower section 11 .

[0026] The support legs 15 provide further stability to the device.

[0027] Furthermore, the material of the sleeve 1 is plastic.

[0028] The use of the sleeve 1 made of plastic material makes the overall weight of the device lighter, making it easier to adjust and rotate the device.

[0029] The method of using the utility model is:

[0030] First, adjust the bottom of the sleeve 1 to be flat to ensure that the laser emitter 4 can stably irradiate the wall. Then, adjust the laser emitter 4 to a predetermined height through the first knob 2, so as to achieve precise control of the mortar joint. When adjusting the height of the laser emitter 4, it is necessary to observe the scale 14, and accurately adjust multiple devices to the specified height through the scale 14.

[0031] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
