Description

Ratchet wrench quick release device

The present invention relates to the technical field of wrench tools, and more particularly to a ratchet wrench quick release device.

Generally, the socket wrench includes a wrench handle and a plurality of sleeves of different sizes. The user can select a suitable sleeve size according to the size of the screw or nut to be disassembled and assembled before operation, and then select the sleeve. The rear sleeve is inserted into the working end of the wrench handle, and the assembly of the sleeve is fixed through the internal fastening structure of the working end, whereby the user only needs to hold the grip of the wrench, and the swinging wrench grip drives the sleeve to rotate, In order to achieve the purpose of disassembly and assembly.

Please refer to the Republic of China Patent Publication No. M426472 "Thumbs clamp device". The wrench mainly includes a wrench body having at least one receiving portion, a ratchet ring seat disposed on the wrench body receiving portion, and a ratchet ring. a ratchet device between the seat and the wrench body, and at least one clamping device disposed on the ratchet ring seat; wherein the ratchet ring seat is provided with an outer ring ratchet on the outer ring surface, and the inner ring surface is opened The inner twelve-corner sleeve portion is provided with an elastically stretchable clip assembly on the adjacent wall between two adjacent inner corners of the sleeve portion, and the clip assembly can be simultaneously protruded The sleeve faces of two adjacent inner corners; thereby, . . .

The foregoing enumerated ones are common socket wrenches on the market, in which the elastic body in the clamping device drives the displacement of the beads to be fixed by the sleeve, so that The user operates it; however, since there is no control device between the elastic member and the bead that can be used to loosen the bead body, that is, the combination of the elastic member and the bead constitutes a normality to the bead body toward the sleeve. The direction is pushed to form a card offset. Therefore, when the sleeve is to be detached and replaced, it must be larger than the top end of the elastic member to open the bead body to detach the sleeve, which causes the operator's hand fatigue and use. The inconvenience is one of the disadvantages in the use of the above-mentioned wrench structure.

Moreover, if the use of the above-mentioned wrench structure is required, the operation of frequently disassembling the sleeve must be performed, since each sleeve can not be quickly disengaged from the sleeve, and further, the efficiency is lowered and the working time is extended. The second disadvantage of the use of the wrench structure.

In summary, the current difficulties and shortcomings of the wrench used in the assembly technology of the limit sleeve are as follows:

1. Since the structure of the limit sleeve lacks the structure for controlling the loosening mechanism, the sleeve assembled by the wrench cannot be quickly detached, resulting in inconvenience in use.

2. Because the sleeve used by the wrench cannot be disassembled quickly, it also causes the use of the wrench to extend the working time and the efficiency is low.

Therefore, it is the case that the creator of the above-mentioned wrench-type wrench structure cannot quickly disengage the sleeve of the limit combination, resulting in inconvenience in use, and inefficiency in operation and use and prolonged working hours. The difficulty point to solve.

The main purpose of the present invention is to provide a ratchet wrench quick release device, and a structure for controlling the loosening mechanism in the sleeve limit structure, so that the sleeve for the wrench can be quickly disassembled and removed and subsequently replaced. , effectively improve the user Convenience and improvement of work efficiency and shortened working hours are achieved with multiple advancements.

In order to achieve the above purpose and effect, the ratchet wrench quick release device is used for assembly of a limit sleeve, which comprises: a wrench having a handle segment and a drive segment, the drive segment is provided with a ratchet a ratchet ring is provided with a ratchet ring surface on the outer peripheral side, the ratchet ring is provided with an assembly hole of the sleeve sleeve, and the ratchet ring is further provided with a pressing groove and is located at one side of the assembly hole, the assembly hole The inner wall ring is provided with an inner ring groove and communicates with the pressing groove; a buckle member is installed in the inner ring groove of the ratchet ring; a pressing rod has a pushing portion at the lower portion and a loosening groove at the middle portion, the pressure The rod set is disposed in the pressing groove; and a spring is disposed at the bottom end of the pressing groove and elastically abuts against the lower end of the pressing rod, so that the pushing portion of the pressing rod corresponds to the inner ring groove and pushes the buckle member into the assembly hole and the sleeve abuts the sleeve The pressure bar compresses the spring so that the loose groove corresponds to the buckle member, and the buckle member elastically disengages from the limit sleeve and exits the assembly hole and enters the loose groove.
