Abstract
A round and square tube scriber comprises a fixed column, wherein a first positioning wheel and a second positioning wheel are connected to two ends below the fixed column; the first positioning wheel and the second positioning wheel are placed on two sides of the circular tube or the square tube, the bottom end of the top column is located at the center line position of the circular tube or the square tube, and the center line can be quickly and accurately scribed on the circular tube or the square tube by pushing the fixing column back and forth; the utility model is simple in operation, have labour saving and time saving and efficient advantage height.
Description
Technical Field
The utility model relates to a round and square tube scriber.
Background
Usually, when a central line is drawn on a circular tube or a square tube, the thickness of the circular tube or the square tube needs to be measured, then, a vernier caliper is adjusted, and the central line is drawn on a horizontal table, so that time and labor are wasted, and the efficiency is low.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide a square tube scriber which is simple in operation, time-saving, labor-saving and high in efficiency.
In order to achieve the purpose, the utility model adopts the technical scheme that:
the utility model provides a round and square tube scriber, includes fixed column 2, and 2 below both ends of fixed column are connected with first locating wheel 1, second locating wheel 5, and 2 below middle parts of fixed column are connected with fixation nut 6, and 2 centre holes of fixed column install fore- set 3, and 3 bottoms of fore-set and 6 threaded connection of fixation nut, 3 tops on the fore-set are connected with handle 4.
The fixing column 2 is uniformly distributed with a plurality of mounting holes of the first positioning wheel 1 and the second positioning wheel 5.
The fixing column 2 is hollow.
The top pillar 3 is provided with threads and is in threaded connection with the fixed pillar 2.
The bottom end of the top column 3 is conical.
The handle 4 is inserted into the upper part of the top column 3, and the diameter of the rear end of the handle 4 is larger than that of the rod part of the handle 4.
The utility model has the advantages that:
utilize first locating wheel 1, second locating wheel 5 to place in pipe or square both sides, 3 bottoms of fore-set are in pipe or square central line position, through making a round trip to promote fixed column 2, can be fast, accurate mark the central line in pipe or square pipe. The utility model is simple in operation, have labour saving and time saving and efficient advantage height.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a side view of the present invention.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1 and 2, a round and square tube scriber comprises a fixed column 2, wherein two ends of the lower part of the fixed column 2 are connected with a first positioning wheel 1 and a second positioning wheel 5 through bolts and nuts, a fixing nut 6 is welded at the middle part of the lower part of the fixed column 2, a top column 3 is installed in a middle hole of the fixed column 2, the bottom of the top column 3 is connected with the fixing nut 6 through threads, and the top of the top column 3 is connected with a handle 4.
The fixing column 2 is uniformly distributed with a plurality of mounting holes of the first positioning wheel 1 and the second positioning wheel 5, and is suitable for scribing round and square pipes of various sizes.
The fixing column 2 is hollow, so that the whole mass is reduced.
The top pillar 3 is provided with threads, is in threaded connection with the fixed pillar 2 and is fixed on the fixed pillar 2 through a fixed nut 6.
The bottom end of the top column 3 is conical, so that the round and square tube can be conveniently scribed.
The handle 4 insert 3 upper portions at the fore-set, handle 4 rear end diameter is greater than handle 4 pole portion diameter, provides big moment of torsion when preventing to drop.
The utility model discloses a theory of operation does:
first locating wheel 1 and second locating wheel 5 are placed in pipe or square both sides, utilize 3 front ends of fore-set to be in pipe or square central line position, and twist grip 4 makes 3 front ends of fore-set hug closely pipe or square surface of pipe, make a round trip to promote fixed column 2, draw a line at pipe or square central point fast.
