Wrench ratchet block structure

The present invention belongs to the technical field of a ratchet wrench, and specifically refers to a wrench ratchet prevention structure in which the ratchet does not fall off arbitrarily when the tool head is replaced, thereby improving the convenience of the ratchet wrench replacing the tool head.

Pressing, the ratchet wrench has a tool head that can be selectively unidirectionally actuated. The tool head is divided into a tilting wheel that can directly screw a nut such as a nut or a bolt, and a tilting member that is screwed through the sleeve, so that the ratchet When the wrench is rotated, the screw can be directly driven through the tool head or the screw can be driven indirectly by the sleeve to achieve the purpose of locking or releasing the screw in one direction, so as to solve the problem that the traditional wrench needs to be separated and re-engaged when driving. The problem is to improve the simplicity and speed of its locking or releasing operation; in recent years, the ratchet wrench with replaceable tool head has been further developed, such as the "ratchet wrench for easy replacement of the tool head" and the announcement of China Patent Publication No. 578646 These structures have different problems, such as the ratchet wrench replacement structure of No. I347247. For example, in the case of Announcement No. 578646, the ratchet of the case may have a tilting problem when the tool head is moved backward to replace the tool head. . In addition, in the case of No. I347247, the ratchet of the case is set to be translated by the pressing plate close to the upper cover, and overcomes the aforementioned problem of the announcement No. 578646. However, in order to facilitate assembly, it is designed as an open type dial, but the ratchet will occur. There is a lack of limit, and there is a problem of falling off, which causes inconvenience in replacing the tool head. Therefore, the existing one cannot satisfy the convenience of replacing the tool head, and further improvement is necessary.

The reason is that the creator is aiming at the aforementioned ratchet wrench to prevent spines. The problems faced by the block are discussed in depth, and through years of experience in research and development and manufacturing of related industries, we actively seek solutions. After long-term research and development, we have successfully developed a wrench ratchet structure. It overcomes the inconvenience and trouble caused by the inability of the existing spine to effectively limit the position.

Therefore, the main purpose of the present invention is to provide a wrench ratchet prevention structure, thereby effectively preventing the ratchet from falling, which can avoid the loss of components and can effectively improve the convenience of replacing the tool head.

To this end, this creation mainly uses the following technical means to achieve the purpose and effectiveness of the creation: it comprises a wrench, a ratchet and a tool head; wherein: at least two ends of the wrench One end has a head, and a wheel groove for receiving the tool head is formed in the head, and a head groove is formed on the periphery of the wheel groove adjacent to the trigger rod, and a bottom groove is formed for the bottom edge of the groove. The ratchet is abutted against the surface, and a guiding groove corresponding to the sliding and pushing of the two sides of the ratchet is formed on the abutting surface, and a receiving groove is formed on the inner wall surface of the head adjacent to the triggering rod, and the head is The top surface lock is provided with a cover sheet for the top surface of the ratchet block, and the cover sheet is formed at the edge of the adjacent wheel groove with a push-pull groove corresponding to the sliding and backward pushing on both sides of the ratchet block, the push-pull groove has A selective release of the release block of the spine; and the surface of the spine is formed with a corresponding plurality of ratchet teeth on the surface of the tool head, and a guide post corresponding to the abutting guide groove is protruded from the bottom surface of the spine block, and the top surface of the spine block Having a guide block corresponding to the aforementioned cover sheet pushing groove, and another ratchet in the side surface of the ratchet Adjacent the top edge of the insert is formed with a slide, furthermore ratchet block A set of dials for dialing is formed on the back surface, and an insert block is arranged in the head receiving slot. The insert block is provided with a top push column capable of springing the ratchet block, and the other block is provided with a guide block on the cover piece. The push-pull piece is combined; the outer edge of the tool head is formed with a plurality of ratchet teeth corresponding to the ratchet ratchet teeth, and the outer edge of the tool head is formed with a limit ring groove at the adjacent top edge, and the limit ring groove can be used in the tool The head is disposed in the aforementioned wheel groove and corresponds to the embedded sliding piece of the ratchet.

Therefore, through the specific implementation of the above-mentioned technical means of the creation, the ratchet wrench of the present invention can be moved back to the center point on the pusher blade, and moved to the back surface of the cover sheet to move backward, so that the spine can utilize the guide pillar and the guide. The blocks slide on the abutting guide groove and the cover sheet pushing groove, so that the tool head is taken out for replacement, and the ratchet block is restricted between the cover sheet and the abutting surface of the head, and the cover plate and the guide groove are restricted. Position, the spine does not fall off arbitrarily, so there is no problem of missing components, which can improve the convenience of tool head replacement, so it can greatly increase its added value and economic benefits.
