Description

Woodworking combined T-shaped angle ruler capable of being lengthened Technical Field The utility model relates to the technical field of surveying tools, in particular to a woodworking combined T-shaped angle ruler capable of being lengthened. Background When a woodworker drills holes on a workpiece, the woodworker usually needs to position a cross line by means of various tools such as a ruler, a level bar, a vernier caliper, a compass, a clamp, a pencil and the like, and then uses a pistol drill to drill the holes. The traditional method mainly depends on visual judgment and personal experience of operators, and has obvious limitations that firstly, positioning accuracy is difficult to guarantee and deviation is easy to occur, and secondly, in the actual drilling process, due to the fact that a cross line mark is only relied on, a drill bit is easy to displace due to vibration, and the joggle joint position is easy to deviate and gap are caused. In addition, the process has higher technical requirements on operators, not only has great learning and mastering difficulty, but also has low operation efficiency, and is difficult to meet the requirements of modern woodworking on precision and efficiency. In this regard, the multipurpose woodworking punching scribing ruler disclosed in the prior art (the authorized bulletin is CN 203726475U), can be combined and multipurpose at the same time by one ruler, can finish length measurement simultaneously by independent use or combined use of individual components, can measure the central position, can set symmetrical distances by taking the central point, has various sliding sheets and sliding grooves, can be directly connected to the ruler body through the sliding sheets, is very simple and convenient, and is simpler and more efficient than the copying connection method on the market. However, the line drawing ruler disclosed in the above description still has the following technical problems in the use process that although the line drawing ruler has multiple use functions, the length of the ruler body is fixed, splicing extension according to actual processed objects cannot be carried out, and the use range still has a certain limitation. Disclosure of Invention The utility model mainly aims to overcome the defects in the prior art and provides a woodworking combined T-shaped angle ruler capable of being lengthened. The technical scheme includes that the woodworking combined T-shaped angle ruler capable of being lengthened comprises a main body ruler plate, wherein a positioning assembly is arranged in the main body ruler plate, one end of the main body ruler plate is provided with an angle measuring assembly, the other end of the main body ruler plate is provided with an extension ruler plate, and the extension ruler plate is arranged on the main body ruler plate in a detachable connection mode. Preferably, a sliding clamping groove is formed in the main body ruler plate, and the positioning assembly is connected in the sliding clamping groove in a sliding mode; the positioning assembly comprises an adjusting nut, a sliding block, a T-shaped sliding sheet, a finger block and a rotating hole; One end of the T-shaped sliding vane passes through the sliding block and then is in threaded connection with the adjusting nut, the other end of the T-shaped sliding vane is attached to the bottom of the sliding block, and the sliding block is slidably clamped in the sliding clamping groove through the T-shaped sliding vane; The rotating holes are formed in the two ends of the sliding block, and are located right above the sliding clamping grooves at the same time, and after the distance is determined, the punching machine can conveniently pass through the rotating holes and the sliding clamping grooves to punch holes; The top of the sliding block is attached to the ruler surface of the main body ruler plate, and points to the ruler surface scale marks of the main body ruler plate through integrally arranged finger blocks, and the position of the finger blocks and the position of the rotating holes are correspondingly arranged, so that the punching distance can be conveniently determined. The sliding block and the T-shaped sliding piece integrally form a structure similar to an I shape, the sliding clamping groove is arranged in a T shape, and the sliding clamping groove is clamped in the sliding clamping groove in a sliding manner through the T-shaped sliding piece, so that the sliding block can be connected in the sliding clamping groove in a sliding manner; In order to fix the position of the finger block, the connection tightness between the sliding block and the T-shaped sliding sheet can be adjusted due to the arrangement of the adjusting nut, the T-shaped sliding sheet is limited through the sliding clamping groove, and the sliding block and the T-shaped sliding sheet can be fixed in the sliding clamping groove, so that the position fixing of the finger block is rea
