Further, the notches are arranged equidistantly on the slit.

To sum up, owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:

(1) the utility model discloses be equipped with length adjustable's telescopic leg, be equipped with the slit on the telescopic leg, be equipped with a plurality of breachs on the slit, come fixed sleeve, the flexible length of inner tube through the removal of the fixture block on the elasticity stop device on the slit to the realization can make the tripod shrink through with inner tube retraction sleeve pipe, be convenient for remove other positions with the spirit level body after unpacing apart, can stretch out the length with fixed flexible branch pipe in the breach that corresponds through making the fixture block when reassembling again, because the breach is equidistant range on the slit, whether the length of breach quantity that exposes through the inner tube can the every telescopic leg of short-term determination equals.

(2) When the length of the telescopic supporting leg is adjusted, the length adjustment of one inner tube can be completed only by pressing the clamping block once, and a large amount of time is saved.

(3) Through setting up the telescopic link, the open angle of telescopic leg can be adjusted to the length of adjustment expansion end to can play the fixed action to telescopic leg, need not to set up the ground nail at telescopic leg bottom and fix, be applicable to and use on sclerosis ground.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1

As shown in figures 1-6, a portable reading level comprises a level body 1 and a tripod, wherein a mounting plate 2 is arranged at the top of the tripod, the mounting plate 2 is used for mounting the level body 1, the tripod comprises 3

telescopic legs

3 and 1 telescopic rod, the telescopic rod comprises a fixed end 4 and a movable end 5, the fixed end 4 is fixedly connected with the bottom of the mounting plate 2, two connecting rods are arranged between the movable end 5 and the telescopic legs 3, two ends of the two connecting rods are respectively fixedly connected with the movable end 5 and the telescopic legs 3, the movable end 5 is rotatably connected with the telescopic legs 3 through the two connecting rods, the telescopic legs 3 comprise a

sleeve

6, 2 inner tubes 7 and an elastic limiting device, one end of each inner tube 7 is mounted in the sleeve 6, the length of each adjustable telescopic leg 3 is changed by enabling the inner tube 7 to extend out of the sleeve 6, and the elastic limiting device is positioned on the sleeve, Between inner tube 7, elasticity stop device is used for fixed sleeve 6 and inner tube 7, and elasticity stop device includes sleeve 8, spring 9 and a pair of fixture block 10, and fixture block 10 runs through sleeve 6 and inner tube 7, and the sleeve 8 slides can be followed to the one end of fixture block 10, is equipped with spring 9 in the sleeve 8, makes fixture block 10 can auto-eject and block inner tube 7.

The inner tube is symmetrically provided with a slit 11, the slit 11 is provided with a plurality of notches 12, the fixture block 10 is cylindrical, the diameter of the fixture block 10 is not larger than the width of the slit 11, the side surface of the fixture block 10 is provided with a convex block 13 matched with the shape of the notch 12, the notches 12 are arranged on the slit 11 at equal intervals, when the fixture block 10 is pressed, the spring 9 contracts, and the convex block 13 retracts into the lower part of the notch 12 so as not to clamp the notch 12, thereby enabling the inner tube 7 to slide.

The working principle is as follows: when pressing fixture block 10, because lug 13 retraction breach 12 below, fixture block 10 is cylindric upper end and can freely slides along slit 11, thereby make inner tube 7 can freely retract or stretch out, when needs are fixed the extension length of inner tube 7, only need stop pressing fixture block 10, make lug 13 get into breach 12, thereby make fixture block 10 card in slit 11, because breach 12 is equidistant range on slit 11, the length that can guarantee every flexible landing leg 3 is the same for the number of breach 12 that only needs to make the inner tube 7 that exposes on all flexible landing legs 3, thereby save the time of a large amount of adjustment length.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
