Description

Penetration wrench clamping structure

The present invention relates to a through-type wrench latching structure, particularly a latching structure that moves back and forth to provide a latching action on the sleeve slot, thereby enabling the insertion sleeve to produce a quick latching and releasing effect.

According to the current application of tools, the through-type socket or wrench structure can meet the needs of various usage conditions, and is therefore quite popular among operators; however, most wrenches that use through-type sockets generally have an elastic locking bead in their working hole, and when the socket is inserted, the steel bead is forcibly locked against, thereby achieving a state where the socket and the wrench are combined and positioned.

However, although the above structure can produce the effect of sleeve positioning, since the engagement and disengagement of the sleeve must be operated forcefully, it is not only very laborious to use, but also has the possibility of wearing out the tool structure.

In view of the fact that there is still room for improvement in the design of hand tool clamping, the inventor, based on many years of experience and technology in the related industry, has started to study solutions and further developed the penetrating wrench clamping structure of the present invention.

One purpose is to control the forward and backward movement of the ratchet structure by means of the locking structure at the rear end, so that when the sleeve is inserted into the ratchet hole, the insertion sleeve can produce a quick locking and release effect.

The second purpose is that by adding a stopper structure at the rear end of the ratchet structure, the space of the original ratchet structure will not be affected, thereby ensuring the strength of the original torque, and the thickness of the wrench head will not be increased, which can meet the convenience of the operating space.

The third purpose is that when the socket and the wrench are engaged or released, the locking structure can automatically reset forward through the push of a spring, thereby providing the user with the convenience of one-handed operation.

In terms of structural design, the present invention has a ratchet structure (12) disposed inside the wrench head (11) of the wrench body (10), and a latching structure (13) is disposed at the rear end of the ratchet structure (12); the latching structure (13) is mainly provided with a circular through hole (20) on the wrench head (11), and an upper limit groove (21) and a lower limit groove (22) are provided at the upper and lower parts of the front end of the circular through hole (20), and the circular through hole ( A spring groove (23) is dug out at the center of the rear end of the circular through hole (20), and a spring (24) is placed in the spring groove (23); wherein an upper clamping block (30) is provided at the upper end of the circular through hole (20), and an arc-shaped notch (31) is formed at the front end of the upper clamping block (30), and a connecting column (32) extends downward from the inner end surface of the upper clamping block (30), and the rear end of the connecting column (32) is a plane, and the front end is in an arc shape, and a locking hole (31) is provided inwardly at the lower end thereof. 4), and an upper limit block (33) protrudes forward from the upper end of the connecting column (32); in addition, a lower card block (40) is provided at the lower end of the circular through hole (20), and an arc-shaped notch (41) is formed at the front end of the lower card block (40), and a connecting groove (42) is pre-set on the inner end surface of the lower card block (40), and a through hole (43) is dug in the connecting groove (42), and a convex lower limit block (44) is provided at the front end of the connecting groove (42); when the upper card block (30) is installed When it is arranged in the circular through hole (20), its upper limit block (33) is clamped in the upper limit groove (21), and the connecting column (32) is connected to the connecting groove (42) of the lower clamping block (40), and is locked in the locking hole (34) of the connecting column (32) through a locking piece (45), and the lower limit block (44) of the lower clamping block (40) is clamped in the lower limit groove (22), and the spring (24) in the spring groove (23) is against the flat end of the connecting column (32).

Next, please refer to Figures 5, 6, 7 and 8. When the latching structure (13) moves forward and backward, the upper and lower latching blocks (30) (40) can be limited by the upper and lower limit blocks (33) (44) in the upper and lower limit grooves (21) (22) to achieve the effect of linear positioning; and the sleeve (50) matched with the latching structure (13) is mainly composed of an upper sleeve connection part (51) and a lower working part (52), wherein the sleeve connection part (51) is provided with an annular upper slot (53) and a lower slot (54); therefore, when the sleeve (50) is inserted from the ratchet structure (12), the user needs to pull the latching structure (13) to move backward so that the sleeve (50) The upper slot (53) is able to pass through the lower stopper (40), and when the sleeve (50) is continuously pushed upward from its upper and lower slots (53) (54) to the same height as the upper and lower stopper blocks (30) (40), the upper and lower stopper blocks (30) (40) are pushed by the spring (24) so that the arc-shaped notches (31) (41) at the front end are engaged with the upper and lower slots (53) (54), thereby completing the engagement of the sleeve (50); and when releasing, it is only necessary to pull the stopper structure (13) backward to disengage the upper and lower stopper blocks (30) (40) from the engagement with the upper and lower slots (53) (54) of the sleeve (50), thereby achieving the release state of the sleeve (50).

Furthermore, please refer to Figures 9 and 10. Since the latching structure (13) of the present invention is used on a one-way ratchet wrench, if the user wants to operate in the reverse direction, the sleeve (50) needs to be inserted in the reverse direction. The latching and releasing of the latching structure (13) for the sleeve (50) in the forward and reverse directions are operated in the same manner.
