Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As shown in Figure 1, 2, the multifunctional ruler 5 that the utility model one preferred embodiment is provided is made up of first chi 10, second chi 20 and lock(ing) bolt 30, wherein:

First chi 10 is formed with a protruding seat 11 in the major axis of end face to an end, the center of protruding seat 11 is equipped with a screw 12 to run through first chi 10, several ribs 13 that screw 12 peripheries in the protruding again seat 10 are arranged with predetermined angular radially (are formed with eight ribs in the present embodiment, and the interval angle between bar and the bar forms 45 degree), in addition first chi 10 in the bottom surface minor axis to both sides be extended with a rail bar 14 of symmetry respectively, and then constitute major axis to a slide rail 15;

Second chi 20 is located on first chi 10, second chi in major axis to offering a flat narrow shape guide hole 21 that runs through, and in self minor axis to both sides be provided with scale 22, the predetermined position of second chi 20 self end is provided with an embedding folder portion 23, pull in several ribs 13 of first chi 10 for folder, and then allow first chi 10 and second chi 20 be constituted predetermined angle, in addition second chi 20 can be accordingly be located at first chi 10 along the slide rail 15 of first chi 10;

Lock(ing) bolt 30 has one twisted 31 and a spiral shell body 32, spiral shell body 32 is located at twisted 31 below, the spiral shell body 32 of lock(ing) bolt 30 can be arranged in the flat narrow shape guide hole 21 of second chi 20 by second chi, 20 tops simultaneously, and be screwed into screw 12 in first chi 10 with its spiral shell body 32, impel twisted 31 of lock(ing) bolt 30 can push against in second chi 20 adjusting the packing degree, and then allow second chi 20 be able to move maybe to adjust start.

The above has disclosed the structure of multifunctional ruler 5, connection relationship and the relevant position between each member, describes the use situation of multifunctional ruler 5 below in detail.

As shown in Figure 3 and Figure 4, when user's desire is used to multifunctional ruler 5 to take measurement of an angle, earlier lock(ing) bolt 30 is unscrewed, make lock(ing) bolt 30 be located away from first chi 10 and second chi 20, this moment, the user can be required according to it, second chi 20 is pulled in one of several ribs 13 of first chi 10 with embedding folder portion 23 folder of himself, and then allow first chi 10 and second chi 20 constitute required angle to be applicable to each occasion, as Fig. 3,4 show the occasion of 90 ° and 135 ° respectively, after then the spiral shell body 32 of lock(ing) bolt 30 being passed the flat narrow shape guide hole 21 of second chi 20, spiral shell is located at the screw 12 of first chi 10 again, and twisted 31 of turn-knob lock(ing) bolt 30, when screwing lock(ing) bolt 30, first chi 10 and second chi 20 will be subjected to be fixed in predetermined angular to pulling and concern, in order to measure angle.

Certainly the user also can make second chi 20 up the embedding folder portion 23 of second chi 20 need not press from both sides several ribs 13 of pulling in first chi 10, but after directly the spiral shell body 32 of lock(ing) bolt 30 being passed the flat narrow shape guide hole 21 of second chi 20, spiral shell is located at the screw 12 of first chi 10 again, and twisted 31 of turn-knob lock(ing) bolt 30, this moment, first chi 10 and second chi 20 can be according to the required any adjustment angles of user.

The another kind enforcement state that is illustrated in figure 5 as multifunctional ruler 5 is that straight line measures and the usefulness of promoting the extension lengthening of measuring length, when aforesaid multifunctional ruler 5 behind the end of operation that measures angle or when desiring to be directly used in line measurement, unscrew lock(ing) bolt 30 earlier and again the embedding folder portion 23 of second chi 20 is separated the rib 13 of first chi 10, allow second chi 20 dismantle in first chi 10, then the user can be with second chi 20 accordingly along the slide rail 15 of first chi 10 and be located at first chi 10 and coincide mutually to be, after at last the spiral shell body 32 of lock(ing) bolt 30 being passed the flat narrow shape guide hole 21 of second chi 20, spiral shell is located at the screw 12 of first chi 10 again, twisted 31 of lock(ing) bolt 30 can tighten at this moment, impel second chi 20 can carry out the flexible start of straight line slippage along the slide rail 13 of first chi 10, and then the extension of promoting line measurement length extends, allow the user adjust required straight line measurement length, twisted 31 of last turn-knob lock(ing) bolt 30 again, when screwing lock(ing) bolt 30, first chi 10 and second chi 20 will be subjected to pulling fixing, therefore first chi 10 and second chi 20 promptly have the steady status of unexpected slip, in order to measure the straight length or the degree of depth.
