Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a carpenter uses chisel with positioning mechanism, includes chisel body 1 and positioning mechanism, positioning mechanism by with chisel body 1 swing joint's adapting unit and clamping member constitute, clamping member includes: the device comprises a shell 2, wherein a threaded rod 5 is arranged inside the shell 2; the two gear assemblies are arranged inside the shell 2, and the bottom of the two gear assemblies is provided with a clamping block 9 so as to clamp and fix the cylindrical wood;
the connecting member includes: the fixing plate 3 is arranged on the outer wall of the shell 2, and a circular hole is formed in the fixing plate 3; the movable frame 4 is arranged in the circular hole, and the movable frame 4 is provided with a splicing through groove penetrating through the chisel body 1.
Specifically, as shown in fig. 1, an annular sliding groove is formed in the inner wall of the circular hole, and a sliding block matched with the sliding groove is arranged on the outer wall of the movable frame 4. The cross-section of spout and slider is semi-circular, and the slider can slide along the spout, still can rotate in the spout simultaneously, so realize that the movable frame 4 rotates around the circular port, can also overturn simultaneously, and then increase the scope that the chisel can remove, makes things convenient for carpenter's operation.
Specifically, as shown in fig. 2-3, the gear assembly includes a gear 6 and a rack 7 that are engaged with each other, a clamping block 9 is fixedly disposed at the bottom of the rack 7, a guiding through groove 8 is disposed at the bottom of the housing 2, and the rack 7 penetrates through the guiding through groove 8.
The gears 6 of the two gear assemblies mesh with each other and the gear 6 of one gear assembly meshes with the threaded rod 5. The two gears 6 are meshed with each other and can synchronously rotate under the driving of the threaded rod 5, so that the two racks 7 can reversely and synchronously move.
One of the two gear assemblies is provided with a clamping block 9 at the bottom and the other is provided with two clamping blocks 9. Through setting up three grip block 9 and helping improving the ligneous stability of centre gripping, because triangle-shaped has higher stability, so three grip block 9 is difficult for producing after cliping from ligneous both sides respectively and is become flexible and skew, helps improving the precision that the chisel knocked when opening the tenon.
Specifically, as shown in fig. 2, one end of the threaded rod 5 extends to the outside of the housing 2, and is provided with a crank 10. When the wood clamping device is used, the rocking handle 10 conveniently drives the threaded rod 5 to rotate, the threaded rod 5 and the gear 6 are meshed with each other, so that the gear 6 can be driven to rotate, and after wood is clamped, the gear 6 actively rotates and cannot push the threaded rod 5 to rotate, so that self-locking is formed, and the clamping stability is improved.
