The inner side of one end of the screw connector 44 close to the clamping nut 41 is provided with a tubular deformable spring plate 43, and the inner diameter of the spring plate 43 is matched with the diameter of the turning tool rod 4. Preferably, the elastic piece 43 is made of a silica gel material. One end of the elastic sheet 43 close to the first tool holder 1 and the inner wall of the wire aligning joint 44 are provided with a limiting step 45 for limiting the elastic sheet 43. The locking clamp 42 is sleeved between the elastic sheet 43 and the wire aligning joint 44 and outside the elastic sheet 43.

Preferably, a plurality of openings are uniformly distributed on the side wall of one end of the locking clamp 42, which is far away from the first tool holder 1, so as to form a clamping jaw capable of centering and contracting, each opening is obliquely arranged relative to the cross section of the locking clamp 42, and each opening forms a spiral shape. Preferably, the end of the clamping nut 41 away from the first tool shank 1 is open as an inlet end, and the diameter of the inlet end gradually converges from inside to outside. The outer diameter of the end of the clamp 42 adjacent the packing nut 41 is between the maximum and minimum diameters of the inlet end.

Preferably, a first connecting block 2 is arranged at the joint of the first tool holder 1 and the second tool holder 11, an annular rotating block 24 is fixed on the periphery of the middle part of the first connecting block 2, and a rotating groove 23 for the rotating block 24 to rotate and to move along the length direction of the tool holder is fixed at the position of the rotating block 24 and on the inner wall of the first tool holder 1. The inner side of the second tool handle 11 is provided with a second connecting block 3 which can rotate downwards relative to the first connecting block 2 and is tightly attached to the inner wall of the second tool handle 11. The outer wall below the first connecting block 2 is provided with a limiting groove 25 for inserting the outer edge of the second knife handle 11 when the second connecting block 3 rotates downwards.

Preferably, the outer side of one end of the second connecting block 3, which is far away from the first connecting block 2, is provided with a plurality of sliding blocks 33, and sliding grooves 32, which are used for the sliding blocks 33 to slide along the length direction of the tool holder, are respectively arranged at the positions of the sliding blocks 33 and on the inner wall of the second tool holder 11. Preferably, a fixing plate 21 is vertically fixed at one end of the first connecting block 2 far away from the second connecting block 3 and at the inner side of the first tool holder 1, a spring 22 with one end fixedly connected with the fixing plate 21 and the other end being a free end is arranged between the fixing plate 21 and the first connecting block 2.

Based on foretell structure, the utility model discloses a handheld carpenter's sword with first handle of a knife 1 and 11 threaded connection of second handle of a knife, then will connect 44 and 1 threaded connection of first handle of a knife to the silk, with the locking clamp 42 cover outside shell fragment 43, will overlap the locking clamp 42 that is good again and shell fragment 43 wholly put into the one end of keeping away from first handle of a knife 1 to the silk joint 44 in, until reacing spacing step 45 department. Then the lathe tool bar 4 is inserted into the channel inside the elastic sheet 43, and the packing nut 41 is sleeved outside the lathe tool bar 4 and is in threaded connection with one end of the screw joint 44 far away from the first tool handle 1. When will compel tight nut 41 and screw on to screwed joint 44, compel tight nut 41's outer end and continuously extrude the clamping jaw of locking clamp 42 for the clamping jaw centering shrink gradually, thereby make shell fragment 43 hug closely on inboard lathe tool pole 4, press from both sides the lathe tool pole 4 and press from both sides tightly fixed, accomplish the utility model discloses a handheld carpenter's sword installation. If the lathe tool bar 4 needs to be taken out, the packing nut 41 is screwed, so that the extrusion of the packing nut 41 to the locking clamp 42 is gradually reduced until the lathe tool bar 4 can be pulled out, and then the lathe tool bar 4 can be taken out. When needs will the utility model discloses stretch into comparatively narrow and small space, or when vertical application of force is not very convenient, can loosen soon first handle of a knife 1 and second handle of a knife 11, at the pine in-process of revolving, relative rotary motion is done to first handle of a knife 1 to second handle of a knife 11, and first connecting block 2 and second connecting block 3 also rotate simultaneously with second handle of a knife 11 simultaneously, and turning block 24 on the first connecting block 2 is rotatory along rotating groove 23 in rotating groove 23. After the first tool handle 1 and the second tool handle 11 are completely separated, the first tool handle 1 and the second tool handle 11 are pulled in opposite directions until the rotating block 24 reaches one end of the rotating groove 23 closest to the second tool handle 11, and the sliding blocks 33 on the second connecting block 3 reach one end of the sliding grooves 32 closest to the first tool handle 1. During the process that the rotating block 24 moves to the end of the rotating groove 23 closest to the second tool shank 11, the spring 22 continuously applies pushing force to the first connecting block 2. And then the second tool handle 11 is shifted downwards, so that the second connecting block 3 rotates downwards relative to the first connecting block 2 until the outer edge of the second tool handle 11 is inserted into the limiting groove 25.

The embodiments of the present invention have been described in detail with reference to the drawings, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
