Tool structure that can be straight in and out and assist in cutting out

The present invention relates to a tool structure that can be straight in and out and assists in cutting out a knife, in particular, a manual spring driven blade can be assisted by manually moving the blade to move a predetermined stroke and overcome a predetermined resistance. The tool structure of the knife.

One of the prior art straight-in and straight-out type cutters, as shown in Taiwan Patent No. M341587, "Tool structure for straight-in and straight-out assisted cutting," is added to a tool holder having a body. a knife set comprising: a positioning frame having a spring piece, a moving piece disposed on one side of the positioning frame and connected to the knife body, and two ends respectively connecting the positioning frame and the moving piece and driving the knife body to move a spring. When the prior art tool is used, the tool body is first moved by a distance to push the elastic piece of the positioning frame toward the outside of the shank until the stop portion of the moving piece moves through the elastic piece, and then the spring is restored. The moving piece and the body are ejected.

However, since the above prior art only uses a moving piece to restrict the blade body to the position of the closing knife, and uses a spring to drive the blade body to the knife, even if the user inadvertently collides with the pushing member that can move the blade body. It also often causes the cutter body to directly eject the shank, which causes the prior art tool to have doubts about the lack of safety in use, and needs further improvement.

In view of the problems of the prior art mentioned above, the purpose of the present invention is to provide a tool structure that can be straight in and out and assisted in cutting out, which can only be When the user intends to take out the knife and drive the blade to move a predetermined stroke and overcome a predetermined resistance, the blade is assisted to drive the blade to eject the handle.

As shown in FIG. 4, when the blade 21 of the tool structure of the present invention is received in the shank 10, the receiving end 334 of the positioning elastic piece 333 abuts against the abutting portion 313 of the first pick 31. The locating member 50 can be pressed to the knuckle limit end 334 of the locating elastic piece 333 to ensure that the hoisting end 334 of the positioning elastic piece 333 does not disengage from the knuckle limit end 334. The abutting portion 313 of the first paddle 31 effectively achieves the purpose of preventing the blade 21 from arbitrarily ejecting the shank 10. As shown in FIG. 5, when the keeper positioning member 50 is pushed to be pressed against the convex portion 52, After positioning the clip end 334 of the elastic piece 333, Referring further to Figure 6, the user can continue to push the push button 22 and move the blade 21 toward the open end 101 of the shank 10 before exiting the knife. During the process of the blade, the push button 22 and the blade 21 firstly move the second paddle 32 through the fixing member 34 for a short distance until the pushing portion 323 of the front end of the second paddle 32 aligns the positioning tab. After the knife end limit end 334 of the 333 is pushed away from the abutting portion 313 of the first pick 31, the first pick 31 and the second pick 32 can be driven by the elastic restoring force of the blade spring 35. The blade 21 is moved toward the front end 101 of the shank 10, thereby causing the blade 21 to be ejected from the shank 10 for the purpose of assisting the knives.

When the user pushes the push button 22 and the blade 21 to move, the second pick-up piece 32 is first driven to move a certain distance, and the receiving spring 36 is compressed, and then the first piece is driven by the fixing member 34. The paddle 31 moves. Moreover, if the force of the user pushing the push button 22 and the blade 21 fails to cause the pushing portion 323 of the front end of the second pick 32 to push the receiving end 334 of the positioning elastic piece 333 away from the first dial When the abutting portion 313 of the blade 31, the elastic restoring force of the blade spring 36 pushes the second paddle 32, the blade 21 and the push button 22 back to the position of the blade. That is, if the user only accidentally collides with the push button 22, and does not push the blade 21 to move the predetermined stroke after the blade is intended to be pushed, the force-receiving end 334 of the positioning elastic piece 333 is pushed hard. The blade 21 does not arbitrarily eject the handle 10. This will ensure the safety of the tool structure of this creation.

Referring to FIG. 7, when the blade spring 35 drives the blade 21 to eject the blade handle 10, the blade limiting end 335 of the front end of the positioning elastic piece 333 abuts against the inner end of the blade 21, so that the blade can be avoided. 21 is arbitrarily retracted into the shank 10 due to the force; Referring to FIG. 8 again, when the blade 21 is to be retracted inside the shank 10, the blade unlocking member 60 is first pushed, and the ejector unlocking member 60 is pushed against the convex portion 63 to release the positioning elastic piece 333. The limiting end 335 is pushed away from the inner end of the blade 21, and then the push button 22, the blade 21, the first paddle 31 and the second paddle 32 are moved to the rear closed end of the shank 10 until the positioning elastic piece The blade end stop 334 of the 333 abuts against the abutment portion 313 of the first paddle 31 to receive the blade 21 in the shank 10.
