As shown in the preferred embodiment of fig. 1 and 2, the laser gauge attachment 100 includes a stand body 1 and a lifting member 2. The bracket body 1 is L-shaped, a horizontal portion of the L-shaped bracket body 1 is used for being placed on the ground or a table top, and a vertical portion is used for installing the lifting member 2. The lifting means 2 are used for mounting a laser measuring instrument 10, which in the solution shown in fig. 1 is embodied as a laser line projector, but in other embodiments the laser measuring instrument may also be another measuring instrument, the inventive laser measuring instrument attachment being applicable to a number of different laser measuring instruments.
The elevating member 2 is mounted on the stand body 1, more specifically, on a vertical portion of the stand body 1, and is capable of elevating and lowering movement with respect to the vertical portion. Specifically, the vertical portion of the stand body 1 has a pair of guide grooves 11 on a side facing the elevation portion 2, the extending direction of the guide grooves 11 being a vertical direction; the elevating member 2 has a guide plate 21 on a side facing the vertical portion of the bracket body, the width of the guide plate 21 being substantially equal to the distance between the pair of guide grooves 11, so that the guide plate 11 can be inserted between the pair of guide grooves 11, both sides of the guide plate 11 being located in the guide grooves 11, and the elevating member 2 can be moved up and down with respect to the bracket body 1 by the cooperation of the sides of the guide plate with the guide grooves 11.
The lifting member 2 has a connection portion 22 for connecting a laser measuring instrument on the side opposite to the guide plate 11, and the connection portion 22 may adopt a connection mode that a magnet is attracted to a steel plate, or a connection mode that a dovetail-shaped plastic sliding groove is matched with a sliding rail.
In order to realize the up-and-down adjustment and locking of the laser measuring instrument at any height position, the accessory of the laser measuring instrument also comprises a rack plate 3, a gear 4, a gear shaft 5, an adjusting knob 6, a dynamic friction plate 7, a static friction plate 8 and a return spring 9.
As shown in fig. 3 to 5, the rack plate 3 is mounted on the guide plate 11 of the elevating member 2, which has a certain width W1, and it is conceivable for a person skilled in the art that the rack plate 3 may be formed directly on the guide plate 11. The gear 4 and the gear shaft 5 are installed on the vertical portion of the bracket body 1, specifically, the bracket body 1 has a pair of installation holes 12 provided at both sides of the bracket body 1, respectively, for supporting both ends of the gear shaft 5; a groove 13 is provided between the pair of mounting holes 12 for accommodating the gear 4, and the inner diameter of the groove 13 is larger than that of the mounting hole 12, so that the groove 13 is an open groove, so that teeth of the gear 4 can be exposed and meshed with the rack plate 3, and the up-and-down lifting of the lifting member 2 is regulated by the meshing of the two. Since the gear 4 is fixedly mounted on the gear shaft 5, when both ends of the gear shaft 5 are mounted into the mounting holes 12, the gear 4 is also mounted on the bracket body 1 together with the gear shaft 5, and the gear shaft 5 can move left and right in the mounting holes 12, thereby driving the gear 4 to move left and right together. The gear 4 has a width W2 and its width W2 is smaller than the width W1 of the rack plate 3, which has the advantage that the gear 4 can remain engaged with the rack plate 3 regardless of the movement of the gear 4 to a certain position.
The return spring 9 is provided between the bracket body 1 and the gear shaft 5 for applying an axial elastic force to the gear shaft 5 so that it can be maintained in a position (locking position) when no external force acts. Specifically, the return spring 9 is fitted over the gear shaft 5 with one end thereof abutting against one of the groove bottoms of the grooves 13 and the other end abutting against the end face of the gear 4, and applies an elastic force to the gear shaft 5 by means of the gear 4.

Under the action of the elastic force of the return spring 9, the gear shaft 5 and the gear 4 are located at a position far away from one side of the bracket body 1 where the static friction plate 8 is located, and in this position, the dynamic friction plate 7 and the static friction plate 8 are completely compressed, and no sliding exists between the dynamic friction plate 7 and the static friction plate 8, so that the gear shaft 5 and the gear 4 are fixed at the locking position, the rack plate 4 and the lifting part 2 are also locked at the height position, thereby realizing the locking of the laser measuring instrument 10 in the height direction, and even under the gravity action of the laser measuring instrument, the friction resistance between the dynamic friction plate 7 and the static friction plate 8 can overcome the gravity, and the locking effectiveness is ensured.
When the height of the laser measuring instrument 10 needs to be adjusted, the user pulls the adjusting knob 6 outwards to overcome the elastic force of the reset spring 9, so that the adjusting knob 6 and the fixed movable friction plate 7, the gear shaft 5 and the gear 4 move outwards together, namely move towards one side of the bracket body 1 where the static friction plate 8 is located, when the movable friction plate 7 moves to be separated from the static friction plate 8, the locking of the gear shaft 5 is released, and the unlocking position is preferably an unlocking position, and the distance between the movable friction plate 7 and the static friction plate 8 is not less than 1mm in the unlocking position, so that the gear shaft 5 can rotate freely. When the laser measuring instrument is in the unlocking position, a user can rotate the adjusting knob 6 to drive the gear shaft 5 and the gear 4 to rotate together, then the rack plate 3 and the lifting part 2 are driven to move up and down through the meshing of the gear 4 and the rack plate 3, so that the height adjustment of the laser measuring instrument 10 is realized, when the laser measuring instrument is adjusted to a required position, the user releases the adjusting knob 6, the gear shaft 5 and the gear 4 are restored to the locking position under the action of elastic force under the state of releasing external force, and the movable friction plate 7 and the static friction plate are mutually compressed again, so that the locking is realized.
The utility model adopts the gear and the rack plate to form the height adjusting mechanism, and the width of the gear and the gear shaft is designed to enable the gear and the gear shaft to have movable space, so that the gear shaft is provided with a locking position and an unlocking position, and the rack plate and the lifting part can be locked at any height position by utilizing the locking mechanism formed by the reset spring, the static friction plate and the dynamic friction plate, so that the phenomenon of tooth jumping in the prior art is avoided.
