Abstract

A box wrench having clamping and positioning device is disclosed, which has a containing part at least at one end of the wrench body; a ratchet ring seat mounted on the containing part, wherein the first ring part of the ratchet ring seat penetrates the wrench body to the first surface side, the second ring part penetrates the wrench body to the second surface side; and a clamping and positioning device which is mounted with at least a clamping member capable of moving laterally and expandable in the overlay groove on the first ring part of the ratchet ring seat. Further, a pressure ring is sleeved onto the outer ring surface of the first ring part by an elastic member. The inner ring surface of pressure ring has an expansion groove which can be moved to correspond to the clamping member. Accordingly, when the inner ring surface of the pressure ring corresponds to the clamping member, the clamping member protrudes inwardly out of the overlay groove to clamp and position the socket tool solidly. When the pressure ring is pressed to make the expansion groove correspond to the clamping member, the clamping member is retracted out of the overlay groove to release the socket tool, thereby achieving the practical benefit of ensuring secure female joint and facilitating replacement of socket tool.

Description

Socket wrench with clip positioning device

In particular, the present invention provides a socket wrench with a clamp positioning device that ensures a secure socketing of the sleeve tool and facilitates replacement when the sleeve tool is socketed.

According to the so-called penetrating socket wrench, a ratchet ring seat having an inner polygonal shape is arranged at one end of the socket wrench, and the inner ratchet ring seat is provided with a hexagonal socket end. The sleeve tool allows the longer length bolt to pass through the wrench when the disassembly nut is locked to the longer length bolt, thereby facilitating the disassembly and assembly of the nut. Since the sleeve tool is sleeved in the ratchet ring seat of the socket wrench, in order to prevent the sleeve tool from arbitrarily disengaging the ratchet ring seat of the socket wrench, a clamping device is generally arranged in the ratchet ring seat of the socket wrench, and The sleeve tool is clamped by the clamping device to meet the operator's needs. Please refer to the first and second figures, which are common penetrating socket wrenches 10. The socket wrench 10 is provided with a ratchet ring seat 11 at one end, and is provided with inner angles at the ratchet ring seat 11 The sleeve groove 111 is further provided with a ring groove 112 in the sleeve groove 111 of the ratchet ring seat 11 for mounting an elastically stretchable C-shaped clamping ring 12, a penetrating sleeve tool 20, One end of the sleeve end 201 is provided with an outer hexagonal shape, and a card slot 202 is formed at each corner of the sleeve end 201 so that the sleeve end 201 of the sleeve tool 20 is sleeved on the ratchet ring seat 11 When the sleeve 111 is inserted into the groove 111, the C-shaped clamping ring 12 can be elastically stretched and clamped to the slot 202 of the sleeve tool 20 to prevent the sleeve tool 20 from being disengaged from the sleeve groove 111 of the ratchet ring seat 11; In the elastic tensioning clamping method, in order to facilitate the replacement of the sleeve wrench 10 to replace the sleeve tool 20 of different sizes, the clamping force of the C-shaped clamping ring 12 cannot be It is too large to affect the replacement of the sleeve tool 20, but the clamping force of the C-clip ring 12 is not large, and it is not only easy to cause the sleeve tool 20 to be detached from the sleeve due to the sway caused by the socket wrench 10 during operation. The wrench 10, and because the sleeve tool 20 itself has a certain weight, the sleeve tool 20 is very easy to disengage from the socket wrench 10 under the inadvertent sway of the operator, except that it may fly out to hit the staff or even hit To the processing equipment, there are many potential hazards hidden in the work, so the elastic clamping method is difficult to take into account the convenience of the replacement of the sleeve tool 20 and the sleeve tool 20 is sleeved on the socket wrench. 10 stability.

In view of this, the inventor has been engaged in research and development and production experience of related industries for many years, and has conducted in-depth research on the problems currently faced. After long-term efforts and trials, the inventors have finally developed a tool that not only facilitates the replacement of sleeve tools, Moreover, it can effectively ensure that the sleeve tool is firmly sleeved on the socket wrench to effectively improve the disadvantages of the prior art, which is the design aim of the present invention.

A first aspect of the present invention provides a socket wrench having a clamp positioning device, which is provided with a receiving portion at least one end of the wrench body, and a ratchet ring seat mounted on the receiving portion, the first ring thereof The second portion of the second ring portion extends through the second surface side of the wrench body, and a clamping device is attached to the first ring portion of the ratchet ring seat. a clamping member which can be moved laterally and telescoped to the sleeve groove, and a pressure ring is sleeved on the outer surface of the first ring portion by an elastic member, and the inner ring surface of the pressure ring is provided with a movable corresponding The expansion groove of the clamping member; thereby, when the inner ring surface of the pressure ring corresponds to the clamping member, the inner ring surface of the pressure ring can be used to protrude the clamping member inwardly from the clamping groove to stabilize The clamping jaws are positioned to ensure that the sleeve tool is securely sleeved to the socket wrench to prevent operational hazards due to any detachment.

A second aspect of the present invention provides a socket wrench with a clamping device, which is provided with a receiving portion at at least one end of the wrench body, and is installed in the receiving portion. The ratchet ring seat has a first ring portion extending through the first surface side of the wrench body, and a second ring portion extending through the second surface side of the wrench body, and a clamping device is attached to the ratchet ring seat The first ring portion is provided with at least one clamping member that can be laterally moved and telescoped to the sleeve groove, and the outer ring portion of the first ring portion is sleeved with an elastic member, and the pressure ring is sleeved. The inner annular surface is provided with an expansion groove movable corresponding to the clamping member; thereby, when the pressure ring is pressed to make the expansion groove correspond to the clamping member, the space provided by the expansion groove of the pressure ring can be used for clamping. The piece is outwardly withdrawn from the sleeve groove to disengage the jaw from the clamping sleeve tool, thereby achieving the practical benefit of facilitating the replacement of the sleeve tool.
