Description

A kind of construction carpenter is with the device uniformly punched convenient for timber
Technical field
It is specifically a kind of construction carpenter with the dress that timber is convenient for uniformly to punch the present invention relates to a kind of construction carpenter apparatus It puts.
Background technology
It needs to carry out many things during being built on building sites, such as builds a wall, paints, tying up reinforcing bar, wood Material processing making etc., each operation are all that special worker is needed to carry out operation, and the same instrument that they use is also It is different, and carpenter can be used when carrying out the processing of timber to a variety of instruments, such as planing tool, cramp used in mending pottery or porcelain etc., and in carpenter It is also required to usually drill on plate, when particularly carrying out uniformly equidistant drilling, generally firstly the need of according to two neighboring With pen, equidistantly flower goes out several points in the distance between hole, and when marking picture point with pen, due to multiple continued labelling, error can tire out Meter becomes larger, and troublesome in poeration not convenient enough, while is that the sawdust generated is typically all to be scattered in around working environment in drilling, Be inconvenient to handle.
The content of the invention
In view of the above shortcomings of the prior art, the technical problem to be solved in the present invention is to provide a kind of construction carpenter fields Construction carpenter is with the device uniformly punched convenient for timber.
In order to solve the above technical problems, the present invention provides following technical solutions:
A kind of construction carpenter is with the device uniformly punched convenient for timber, including tablet;The mainboard is horizontal and lower end Four, face vertex is connected with support feet;Side has been horizontally disposed with two bar shaped slideways before and after the tablet upper surface;Described two Left and right ends are vertically arranged with one slide-plate respectively in every bar shaped slideway of bar shaped slideway;The slide plate lower end is connected with cunning It takes turns and pulley card is placed in bar shaped slideway;Level is connected with frame between the slide plate of the homonymy end point of two bar shaped slideways Plate;The frame plate upper horizontal is provided with the connecting plate in front and rear trend and the front and rear end of connecting plate is affixed by connecting rod The front and back end of frame plate;The centre position of the connecting plate be installed with threaded mandrel vertically and threaded mandrel by screw thread it is affixed even Fishplate bar;The tablet upper surface back side edge centre position is connected with the fixed fixed cylinder in downside and the work being inserted in fixed cylinder vertically First telescopic rod of lever composition;The fixed cylinder upper end side-walls of first telescopic rod have crossed fixing bolt and fixing bolt It contradicts on the motion bar side wall being inserted in fixed cylinder;Level is connected in front and rear trend at the first telescopic rod upper end Second telescopic rod of position and the upper front side in the first telescopic rod;Transverse horizontal at the front end of second telescopic rod or so It is connected with support plate;The support plate upper surface back side edge centre position is connected with threaded rod vertically;It is socketed on the threaded rod Have through the affixed nut of screw thread;The support plate upper surface is horizontally disposed with spring and the midpoint rearward position of spring is welded Threaded rod;The left and right ends of the spring are connected with link block;Sliding sleeve is socketed on the threaded rod and sliding sleeve is under nut Side;Connecting rod is provided between the link block of the left and right ends of the sliding sleeve or so lateral wall and spring and the both ends of connecting rod lead to respectively Cross the side wall that link block and sliding sleeve in hinge connection;The front side horizontal of each section of spring is connected with moves towards position in front and rear Connecting tube;The front end of the connecting tube is connected with locating ring by shaft.
As the further improvement project of the present invention:Turning handle is connected at the upper end of the threaded mandrel.
As further improvement project of the invention:Handle is connected on the upside of the nut left and right sidewall vertically.
As further improvement project of the invention:Stop block is connected at the upper end of the threaded rod.
As further improvement project of the invention:It is set among the tablet among fluted and groove inner bottom surface Position is provided with port.
Compared with prior art, the beneficial effects of the invention are as follows:
The pulley of the present invention is convenient for horizontally slipping along bar shaped slideway with slide plate;It is used between frame plate on the slide plate of the left and right sides Plate is put in level frame, and according to the length of plate, slides the slide plate of both sides, adjusts the distance between frame plate of both sides, just Just frame plate material;Threaded mandrel withstands the plate end that frame is placed on frame plate so that plate is fixed, and is convenient for by being rotated down Processing;Turning handle rotates threaded mandrel convenient for user;Fixing bolt is used to on the inside of the fixed cylinder of the first telescopic rod rotatably compress Motion bar fixes the length of the first telescopic rod adjusting;Nut is moved up and down by being rotated on threaded rod;Handle is easy to use Person's rotating nut;Stop block is used to prevent nut from from threaded rod upper end departing from;By being rotated down travelling nut, promote sliding sleeve to Lower slider so that sliding sleeve by connecting rod to both sides promote link block move so that the left and right ends of spring by etc. power stretch; After plate holder is put well, it is first determined the equidistant distance punched is needed, nut is moved down then along threaded rod, Promoting sliding sleeve so that both ends of the spring stretches, and with the distance between one of which two adjacent sections on the good spring of ruler amount, due to Both ends of the spring stress is equal so that spring pulls open identical per the distance between two adjacent sections, so that the positioning of connection Ring is equally spaced, and locating ring then is gone to horizontal level, then passes through the longitudinal direction of the first telescopic rod and the horizontal stroke of the second telescopic rod To adjusting so that locating ring is close to alignment punch position, then so that the drill bit of electric drill is bored through locating ring on plate Hole;It is the sawdust fallen that groove, which is convenient for catching punching, so that sawdust is collected in groove, and ready container is fallen by port It is interior, facilitate processing.
