[Previous technology] Construction, dyeing, and installation of 5 yellow and other projects, which can be used from the surface (XY plane) direction, vertical surface range personnel to use the lightning ray as a reference to shape, as shown in the fifth figure, with a fixed seat (4 0) is assembled on the top) 'in the middle of the shell (50), the top end is provided with two vertical projections 0) the top is provided with a spirit level in the middle and the bottom is assembled with three feet (60 inner rod (6 1 ), And the outer tube (6 is provided with a threaded section at the bottom for the inner rod (6 1) of the outer tube, the bottom of the inner rod (6 丄 4 0), this type of inner rod (6 adjustable feet (60), when The laser is measured by a level meter (53) and it is not located outside the legs (60) outside the tube (62). The laser meter is commonly used in several projection windows to project the level (X ζ Plane) direction line, ink line or construction and adjustment. However, a disc-shaped fixing seat (40) outside the existing laser measuring instrument, and a hollow casing (50 has a horizontal projection window (51)), a window ( 5 2), in addition to the casing (5 (53), fixed seat (4〇)), each leg (60) is composed of 2 ), The inner rod (6 1) (6 2) is screwed to the top of the adjustable rod) and reassembled on the ground by a fixed base (1) and an outer tube (62). (It can be adjusted when it is in the horizontal state) 'Make the laser measuring instrument level 1245884. However, due to the construction, some measurement points are low (such as indoor skirting boards)' Even if the feet (60) are adjusted to the shortest, it is still impossible to measure To, for example, as shown in the sixth figure, the top position of the skirting board is generally marked with the L line, but the horizontal projection height of the existing laser measuring instrument is higher than L and is located at the laser beam li, so that it cannot directly use the projected laser beam. L 丨 is the construction reference. It is necessary to take the lightning ray L1 as the reference, measure downwards at intervals and mark the south difference h (the correct height) of the two lines, and then connect the measurement points to the line. The correct construction height. The minimum measurement height of the existing laser measuring instrument is still too high, which requires further measurements during construction to obtain the correct construction position, which is rather inconvenient, and it is necessary to improve it. Summary of the invention In order to improve the aforesaid defects, the main object of the present invention is to provide a leg of a laser measuring instrument that can be adjusted to a shorter length so as to be suitable for low-point measurement. Based on the above object, the main technical means of the present invention is It includes an inner rod which is assembled on the bottom of the fixed base of the laser measuring instrument, an adjustable rod which is adjustable and assembled on the bottom end of the inner rod, an adjustable tube which covers the inner rod and an outer tube outside the adjusting rod. After applying the above-mentioned technical means, because the legs are set in three stages, the outer tube can be assembled and used, and when the lower position is to be measured, the outer tube can be removed. Only the adjustment rod is assembled on the inner rod to further reduce the height of the laser measuring instrument, and to measure the lower point position. The existing laser measuring instrument cannot measure the lack of the low point position, and the 1245884 after removing the outer tube The feet can still be adjusted to level. [Embodiment] Please refer to the first figure, the laser measuring instrument used in this creation is still the same as the existing product, that is, a fixed base (10) is provided, and a top is provided on the top of the fixed base (10). The outer casing (20) extends above, and there are horizontal projection windows (2 vertical projection windows (2 2), and the middle of the top of the outer & (20)) on the periphery of the middle section and the top edge of the outer casing (20). it * spirit level (2 3) 'on the bottom of the fixed base (1 〇)' s vibration measurement device \ (3 Q) 'Because the laser measurement inside the casing (2 Q) is less than the degree of A-Zhou Zhou Zheng' In order to make the laser measuring instrument Γ position 'specially designed the feet (3 made-Fan design. ° See also the first, 220) and π 丄, and the second figure, the feet of the present invention ( 3 into a three-stage design, basin "〇) bottom Qiu, including one to install on the fixed seat (1 &# 内 杆 (2 Ί adjusting rod (3, one assembled on the bottom of the inner rod (3 1) (Outside of the outside) is covered with the inner rod (3 1) and the adjustment rod (3 2 < outer tube (33), formed by the / edge with & one middle, inner The outer peripheral part of the rod of the cup (3 1) is set as a fixed end ('on the top of the rod body of the inner rod (3 1) ^ in this comparison), so as to be fixed to the bottom of the same seat (1 0) and inside. Among them, the fixed end (3⑴ is-screw, the direction of the recess is concave) (3 3 tune Chu 椁 (32) in 1? 2) screw connection; 2) the internal screw part:-end system Corresponding screw support (321) is provided on the outside of the screw hole (in the inner ridge (3 2 0), and the other end forms a sudden extension), and the top support (3 1245884 2 1) The outer diameter is slightly smaller than the periphery of the outer member (3 丄 〇) of the inner rod (3 1), so as to smoothly insert and cover the outer tube (3 3); the evening camp f Q 〇, Q 3 3 The top of the housing is axially recessed into an accommodating space (3 3 0), and an internal thread section (3 3 1) is provided in the upper half of the accommodating space fq 〇η,, and (3 3 0), Corresponding screw is set on the external thread 0) of the inner rod (3 丄). 丄 The above is the structure of the leg (30) of the present invention, and the entire leg (30: the length after assembly is different from the existing product) No #, that is, you can do the same measurement $ work, however, when the measurement point is low, you can Remove the outer tube (3 3) [as shown in the figure-the outer tube (3 3) is disassembled], so the length of the leg (30) is only the inner rod (3 丄) plus the adjustment rod (3 2) 'The height of the laser measuring instrument can be greatly reduced to perform the lower position measurement operation. As shown in the fourth figure, it is the h-shaped yoke after the outer tube (33) is disassembled according to the present invention. The height has been greatly reduced, and then the proper height and level can be adjusted by the witherable withering rod (3 2). Therefore, the lower level laser light can be emitted by the technology, and the laser light indicator is set directly. The chemical industry does not need to be measured again. Therefore, the use of the car grate in the present invention is extensive and convenient for construction, and it can improve the lack of the low point position that the existing laser measuring instrument cannot measure.
