Ratchet hand tool with a retractable nail puller

The present invention provides a ratchet hand tool having a collapsible nail puller that is related to the structure of the hand tool.

Most of the hand tools are mostly a tool-and-function configuration. For example, the ratchet tool has only the function of ratcheting, and the nail-plucking tool has the function of only pulling the nail; so when it is used, it needs to be prepared. Tools to do different tasks; the tools required to prepare each job become very complicated, and it is more difficult to improve the work front-end work; therefore, there is a composite tool 10 as shown in Figure 1, the composite tool The driving head 12 is disposed on a tool body 11 and a nail removing portion 111 is integrally formed on the tool body 11. Thus, the composite tool 10 can simultaneously provide driving of the driving head 12 and nailing of the nail removing portion 111. Working, one of the composite tools 10 can perform two kinds of work to improve the convenience of work; however, since the nail removing portion 111 is integrally formed on the outer periphery of the tool body 11, when the driving head 12 is used to drive the tool Mostly, it is performed in a rotating manner, so that the nail pulling portion 111 directly affects the range of travel of the driving head 12 to reduce the working applicability of the composite tool 10; The nail removing portion 111 is disposed on the outer periphery of the tool body 11, and the nail removing portion 111 has a sharp tip. When the composite tool 10 rotates to perform a driving operation, the sharp nail removing portion 111 rotates with the compound tool. , causing the use process In view of this, the inventors have diligently studied and further conceived, and after many research and development trials, finally invented a ratchet hand tool with a collapsible nail puller.

The present invention provides a ratcheting tool with a collapsible nail puller whose primary purpose is to address the limitations of the use of conventional compound tools and the lack of safety concerns.

To achieve the foregoing objective, the present invention provides a ratchet hand tool having a collapsible nail puller, comprising: a tool body formed by forming a working head at one end of a grip portion, wherein the working head is provided with a perforation and a device hole, and the working head extends to form an opposite first ear portion and a second ear portion; a ratchet unit includes a spine driving member and a ratchet block, the spine driving member is pivotable Is disposed in the perforation, and the outer peripheral surface of the spin drive member has a plurality of drive member ratchets, and the spine block is pivotally disposed in the device hole, the spine block has a plurality of ratchet block ratchets The ratchet block ratchet meshes with the drive member; and a nail pull unit is pivotally disposed between the first ear portion and the second ear portion of the tool body.

The nail pull unit is pivotally disposed on the tool body, and the nail pull unit can be folded when the nail pull unit is not used, so that the nail pull unit does not affect the use of the tool when not in use, and There are also no security concerns to ensure security in use.

The second ear portion 27 is opposite to the first pivot portion 261. The second pivot portion 271 is a screw hole. The ratchet unit 30 includes a ratchet drive member 31 and a ratchet. The block 32 is pivotally disposed in the through hole 23 of the working head 22 of the tool body 20, and the outer peripheral surface of the ratchet drive member 31 has a plurality of drive member ratchets 311, and the spine The movable block 32 is pivotally disposed in the device hole 24 of the working head 22 of the tool body 20, and the ratchet block 32 has a plurality of ratchet block ratchets 321 , the ratchet block ratchet 321 and the driving member The ratchet teeth 311 are engaged; A nail unit 40 is pivotally disposed between the first ear portion 26 and the second ear portion 27 of the tool body 20, wherein the nail pull unit 40 is provided by a group The portion 41 is formed by a nail removing portion 42. The nail removing portion 42 is formed into a fork shape. One side of the assembly portion 41 is provided with a groove 411, and a through hole 412 is disposed through the groove 411. The outer peripheral surface of the assembly portion 41 has a first abutting surface 413 and a second abutting surface 414. When the first abutting surface 413 abuts against the working head 22, the second and second abutting surfaces 413 are in a folded state. The abutment surface 414 is in a state of use against the working head 22; and the pivot unit 50 includes a resilient spacer 51 and a pivot assembly 52. The pivot assembly 52 is comprised of a pivot assembly head 521, a The pivoting portion 522 and the screwing portion 523 are formed in a sequence, and the resilient spacer 51 is received in the recess 411 of the nail removing unit 40 so that the resilient spacer 51 is located at the first ear portion 26 . And between the nail pull unit 40, the assembly portion 41 of the nail pull unit 40 is disposed between the first ear portion 26 and the second ear portion 27, and the pivot assembly 52 is further defined by the top of the tool body 20. Face 221 The first pivoting portion 261 , the resilient shims 51 , the through holes 412 , and the second pivoting portion 271 are disposed, and the pivoting assembly head 521 of the pivot assembly 52 is received in the tool body 20 .
