Description

Drawbench structure

Technical field

The utility model belongs to hand-held tool technical field, espespecially a kind of drawbench structure.

Background technique

Common drawbench has two kinds of structural shapes as shown in FIG. 6 and 7, using the firm fastening workpiece of clamp arm (such as bearing) reuses screw rod and the shaft member in workpiece is released or pulled out by screw action.Accordingly it is found that drawbench can be correct Operate and the premise that achieves the desired results be the soundness that clamp arm clasps workpiece, if therefore workpiece size it is bigger, clamp arm shape At folder away from the demand for then needing more great talent to be able to satisfy fastening workpiece.

The clamp arm 71 of known drawbench shown in fig. 6 is articulated on the linking arm 72 of a regular length with top, is reconnected One actuating arm 73 forms a folder away from and the maximum distance that clamp arm 71 can open is known as span to drive clamp arm 71 to open.Such as Shown in Fig. 6, when this drawbench use is on biggish workpiece 74, wherein the size of the workpiece 74 between drawbench folder away from across When away between, since clamp arm 71 is articulated in the fixation position of linking arm 72, make its folder away from can not more expand, so that cannot Firm clamping workpiece 74.

And the clamp arm 81 of known drawbench shown in Fig. 7 is slidably attached at the linking arm 82 of a regular length with top On, the folder that can be formed away from equal with span, therefore this style of drawbench can make clamp arm 81 open it is much can be firm Clamp great workpiece 83.However the linking arm 82 of this drawbench is usually longer, thus occupy excessive volume, in storage It is very inconvenient.

Utility model content

The purpose of this utility model is to provide a kind of drawbench structure, the enough spans of expansible are biggish to be formed Folder is away from and then being securable on biggish workpiece, thus expand workable range.

To achieve the goals above, the utility model uses following technical scheme:

A kind of drawbench structure, including a screw rod, a connection piece, a fixing seat and a continuous action base, the fixing seat are equipped with One screw hole, the continuous action base are equipped with a perforation, and the top of the connector is equipped with a special-shaped nut, and the screw rod is spirally connected described different Shape nut is simultaneously stretched through downwards screw hole and is spirally connected the fixing seat, and passes through the perforation of the continuous action base, and the connector is downward Stretch out multiple spaced adjutages, the affixed continuous action base of adjutage, the fixing seat is equipped with multiple the to overhanging One fixed arm, the continuous action base are equipped with multiple second fixed arms to overhanging, and each first fixed arm is respectively between the adjutage Every stretching, and first fixed arm is corresponding with above and below the position of second fixed arm, corresponding first fixed arm and Two fixed arms connect a clamp arm, it is characterised in that:

From the fixing seat obliquely to extending, each second fixed arm is in each first fixed arm from the continuous action base Arcuation extends, and the length of first fixed arm is less than the length of second fixed arm, and first fixed arm is equipped with One extends along the first groove of direction extension, and second fixed arm is equipped with a second groove for extending along direction extension, The clamp arm is slidably installed in the first groove and the second groove with one first convex block and one second convex block respectively.

In one embodiment, the first groove is formed from the bottom surface of first fixed arm is recessed upwards, and described The two sides of first fixed arm open up one first long sliding slot；First convex block is located at the clamp arm in face of the described first long sliding slot Two sides, and slideably stretch through in the described first long sliding slot.The second groove is up and down through second fixed arm It forms, and opens up one second long sliding slot in the two sides of second fixed arm；Second convex block is located at the clamp arm in face of institute The two sides of the second long sliding slot are stated, and are slideably stretched through in the described second long sliding slot.

Further, multiple wavy first positioning depressions are equipped with along the bottom edge of the described first long sliding slot, and along institute The bottom edge for stating the second long sliding slot is equipped with multiple wavy second positioning depressions.

The utility model has the advantages that: the enough spans of drawbench structure expansible of the utility model are biggish to be formed Folder is away from being securable on biggish workpiece, expand workable range；It is applicable to be accounted on biggish workpiece, while integrally Small volume, thus be conducive to store.
