It uses laser lines instead of traditional level bubbles to measure horizontal distances quickly and accurately, reducing construction time and labor costs.

[0003] The laser marking instrument in the prior art usually needs to be fixed on an external object such as a beam, but after this type of laser marking instrument is fixed on the external object, it is difficult to rotate and adjust the position. Utility Model Content

[0004] The utility model aims to provide a marking instrument adjusting device which can freely rotate and adjust the marking instrument after the marking instrument is fixed.

[0005] In order to solve the above problems, the utility model provides a marking instrument adjustment device, including a fixing device and a fixing bracket, wherein the fixing bracket is used to be fixed on a support body, and the fixing device is used to be connected to the marking instrument, and the fixing device includes:

[0006] An adjustment chamber fixed below the fixing bracket, the adjustment chamber having a hollow inner cavity and an opening at the bottom and communicating with the inner cavity;

[0007] An adjusting gear located in the cavity of the adjusting chamber and a columnar adjusting rack meshed with the adjusting gear, wherein a free end of the adjusting rack extends out of the adjusting chamber;

[0008] The bottom of the mounting seat is fixedly connected to the marking instrument, and the top of the mounting seat passes through the opening and is transmission-connected to the adjusting gear.

[0009] As a further improvement of the present invention, the transmission connection between the mounting seat and the adjusting gear is configured as follows:

[0010] When someone works hard, the mounting seat can rotate relative to the adjusting gear;

[0011] Under the action of unmanned working force, the relative rotation between the mounting seat and the adjusting gear can be limited.

[0012] As a further improvement of the utility model, a pressure block is arranged in the adjustment chamber, which is at least partially embedded in the inner wall of the adjustment gear and generates friction with the inner wall to achieve the above-mentioned transmission connection. The pressure block is transmission-connected to the mounting seat via a connecting piece.

[0013] As a further improvement of the present invention, the pressing block includes a fitting portion of a plate-like structure and a contact portion of an annular structure, and the outer wall of the contact portion and the inner wall of the adjusting gear form the friction force of the above-mentioned transmission connection.

[0014] As a further improvement of the present invention, the regulating chamber is composed of a cylindrical body and an upper cover, the pressing block is provided with a threaded hole, and the mounting seat is connected to the pressing block via a threaded fastener.

[0015] The beneficial effect of the utility model is that the utility model is provided with an adjustment chamber, in which an adjustment gear and an adjustment rack are arranged, and a mounting seat fixedly connected to the line marking instrument is transmission-connected with the adjustment gear. When the fixed bracket is fixed to an external object, the adjustment gear is driven to rotate by rotating the adjustment rack, thereby driving the entire line marking instrument to rotate, effectively solving the problems encountered in the prior art.

[0020] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0021] like Figure 1-3 As shown, the utility model includes a fixing device 100 and a fixing bracket 200, wherein the fixing bracket 200 is used to be fixed on a support body, and the fixing device 100 is used to be connected to a marking instrument, and the fixing device 100 includes:

[0022] An adjustment chamber 102 fixed below the fixing bracket 200, wherein the adjustment chamber 102 has a hollow inner cavity and an opening at the bottom and communicating with the inner cavity;

[0023] An adjusting gear 104 located in the cavity of the adjusting chamber 102 and a columnar adjusting rack 106 meshing with the adjusting gear 104, wherein a free end of the adjusting rack 106 extends out of the adjusting chamber 102;

[0024] The bottom of the mounting base 108 is fixedly connected to the marking instrument, and the top of the mounting base 108 passes through the opening and is transmission-connected to the adjusting gear 104.

[0025] As a further improvement of the present invention, the transmission connection between the mounting seat 108 and the adjusting gear 104 is configured as follows:

[0026] When someone works hard, the mounting seat 108 can rotate relative to the adjusting gear 104;

[0027] Under the action of unattended working force, the relative rotation between the mounting seat 108 and the adjusting gear 104 can be limited.

[0028] As a further improvement of the present invention, a pressure block 110 is provided in the adjusting chamber 102. The pressure block 110 is at least partially embedded in the inner wall of the adjusting gear 104 and generates friction with the inner wall to realize the above-mentioned transmission connection. The pressure block 110 is transmission connected to the mounting seat 108 via a connecting piece.

[0029] As a further improvement of the present invention, the pressing block 110 includes a fitting portion of a plate-like structure and a contact portion of an annular structure, and the outer wall of the contact portion and the inner wall of the adjusting gear 104 form the friction force of the above-mentioned transmission connection.

[0030] As a further improvement of the present invention, the regulating chamber 102 is composed of a cylindrical body 112 and an upper cover 114 , the pressing block 110 is provided with a threaded hole, and the mounting seat 108 is connected to the pressing block 110 via a threaded fastener.

[0031] The specific principles of the utility model are as follows:

[0032] (1) Fix the fixing bracket 200 to the external object;

[0033] (2) During normal adjustment: the adjusting rack 106 rotates to drive the adjusting gear 104 to rotate. At this time, because there is friction between the pressing block 110 and the adjusting gear 104 due to the relative motion between the two, the rotation of the adjusting gear 104 will drive the mounting seat 108 and the marking instrument under the mounting seat 108 to rotate;

[0034] (3) Manual rotation: The mounting base 108 is rotated directly by hand, and the torque is transmitted to the adjusting gear 104 fixedly connected to the mounting base 108, which can overcome the friction between the pressure block 110 and the adjusting gear 104, so that the pressure block 110 and the adjusting gear 104 slide against each other, and then the mounting base 108 and the marking instrument can be manually adjusted.

[0035] The technical principle of the present utility model has been described in combination with specific embodiments above. These descriptions are only for explaining the principle of the present utility model and cannot be construed as limiting the protection scope of the present utility model in any way. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the present utility model without creative efforts, and these embodiments will all fall within the protection scope of the present utility model.
