Description of the new model: [Technical field to which the new model belongs] The new model is about a kind of ratchet wrench, especially a palm-type ratchet wrench. [Previous technology] At present, most common ratchet wrenches have a fixed volume. Therefore, for users who have smaller items to lock, a larger wrench volume is often not easy to use flexibly, which causes inconvenience. When you need to reach into a small space, you often feel suffocated, so in this case, using ^-a small size and easy to make the ㈣ ratchet wrench look more effective. Referring to FIG. 1 and FIG. 2, it is a conventional ratchet wrench 10 which is small in size and used in a narrow space, and includes a wrench body u, a ratchet wheel 12, a worm shaft, a sleeve joint 14, a ratchet block 15 'and a Steering wheel 16. The wrench body 11 includes a mounting hole ^ around an axis z, an operating lever 112 formed on one side of the mounting hole 111, and a mounting groove 113 formed at the intersection of the mounting hole 111 and the operating lever 丨 12, And two are respectively corresponding to the pivot holes 114 provided on both sides of the mounting groove 113. The ratchet wheel 12 is disposed in the mounting hole ui around the axis z, and includes the inner ratchet teeth 121 formed mostly on the inner surrounding surface, and the outer ratchet teeth 122 formed mostly on the peripheral winding surface. The worm 13 is provided with a perforation 131 in the center and a continuous majority circle 132 on the outside. The worm 13 is positioned in the mounting groove 113 through a bolt 133 through the joint holes 114 and the perforations 131. The ring 132 is meshed with the ratchet teeth 122 outside the ratchet wheel 12 and can rotate with each other. 5 M261325 The sleeve joint 14 is nested in the ratchet wheel 12 and includes a central hole 141 penetrating along the Z direction of the axis, and a receiving groove 142 provided along the circumferential direction thereof and communicating with the central hole 141. And a joint portion 143 extending from the mounting hole 111 along the axis z direction. The ratchet block 15 is integrated in the receiving groove 142, and has a positioning hole 151 penetrated by a positioning pin 17, and two ratchet portions 152 formed on opposite sides of the positioning hole i5i. The steering wheel 16 is disposed on the side of the joint 14 opposite to the joint portion 143. The steering wheel 16 includes a cover body 161 that can be closed in the mounting hole ill, and a cover body 111 extending into the center hole 141.

In this state, by pulling the operation lever 112 , You can tighten and loosen the screw inspection (not shown), and when the space for movement is limited, or it is not easy to use the pull method, you can generate the action by turning the snail to protect η, To avoid being obstructed. The wooden seat is vivid. However, according to the above structure, the clerk's side is prepared for private use. "The talents 13 and the ratchet 12 are both _ W. It is necessary to drive two components at the same time, which will cost more. On the one hand, the ratchet wheel 12 and the worm wheel 13 must be able to accommodate the miscellaneous sales m. And it will increase the cost and increase the pin. In terms of inter-use, the ring 132 of the M = 6261261 is easy to be contaminated with dust and oil, which makes it difficult to rotate. [New content] 々, therefore ' The purpose of this new model is to provide a low-cost, medium-sized ratchet wrench that can be easily operated and can be used in a small space. Then, the new medium-sized palm ratchet wrench includes a wrench body, a ratchet unit, and a Operating unit. 4 The wrench body includes-a mounting hole, and at least-an operation formed in the mounting hole; f dry. The mounting hole is formed around the axis and sequentially formed a large u, and has ratchets around and the diameter is smaller than The small-aperture section of the large-aperture section. The gastric ratchet unit includes a positioning pin that is set around the axis and is sleeved on the small-aperture section and is parallel to the axis and is positioned on the side of the sleeve joint. A ratchet block that is worn and can be engaged with the ratchet teeth of the small-aperture section.

The ratchet block The positioning pin is combined with the accommodating groove. The early working element includes a steering wheel that surrounds the axis and is sleeved on the large-aperture section and extends along the axis direction, and an ejector rod passing through the steering wheel. Two sets of elastic members between the steering wheel and the ejector rod, and a toggle member provided along the circumferential direction of the ejector talent and extending to the accommodation slot. ° The ejector rod can be directed to the sleeve. The center hole of the joint is protruded, and the ratchet block is moved by the turning member by the rotation of the 7 M261325 steering wheel. [Embodiment] The foregoing and other technical contents, features, and effects of the new model, It will be clearly shown in the following detailed description of the second preferred embodiment with the 5 Cangkao pattern. Before the new model is described in detail, it should be noted that in the following description, similar elements are represented by the same number. As shown in Figures 3 and 4, the first preferred embodiment of the new palm-type ratchet wrench includes a wrench body 20, a ratchet unit 30, a retaining ring 40, and an operating unit 50. 4 The wrench body 20 includes a mounting hole 21 and two operating levers 22 formed on opposite sides of the mounting hole 21. The mounting hole 21 surrounds an axis z and sequentially forms a large aperture section 211, and a small aperture section 212 surrounded by ratchet teeth 2B and having an aperture smaller than the large aperture section. The ratchet unit 30 includes a socket joint 3 丨 surrounding the axis z and sleeved on the small-aperture section chuan, a position lock 32 arranged parallel to the axis z on the side of the socket joint si-, and a A ratchet block 33 penetrated by the positioning pin 32 and engageable with the ratchet teeth 213 of the small Lu · aperture section 212. Kouhai socket 31 has a central hole 311 running along the z-direction of the axis: a fastening groove M2 provided on the large-diameter warp section 2m along the circumferential direction thereof and a circumferential direction provided on the small-aperture section 212 A receiving groove 313 in the middle and communicating with the central hole Π, a bean circle 3 & & / σ, a turning part 3 14 protruding in a circumferential direction outside the small aperture section 212, and an axis along the axis Ji 7+ 丄 / 口 A sleeve line Z direction extends from the joint portion 3 15 outside the small aperture section 212. 8 M261325 The positioning pin 32 and the ratchet block 33 are combined in the accommodating groove 3 13. The ratchet block 3 3 has a positioning hole 3 31 penetrated by the positioning lock 32 and is formed in The ratchet portions 3 3 2 on opposite sides of the positioning hole 3 3 1. The buckle 40 is fastened in the fastening groove 312 so that the sleeve joint 31 is rotatably fixed to the mounting hole 21. The operation unit 50 includes a steering wheel 51 that surrounds the axis z and is sleeved on the large-aperture section 211, an ejection rod 52 that extends through the steering wheel 51 along the axis z direction, and a set of steering rods. An elastic member 53 between the disc 5 and the ejector lever 52, and a shifting member 54 provided in the circumferential direction of the ejector lever 52 and extendable to the receiving groove 313. In this embodiment, the elastic member 53 is a compression spring, and the toggle member 54 is a short rod sleeved with a spring. The ejection lever 52 can protrude into the central hole 311 of the sleeve joint 31, and the ratchet block 33 is moved by the pusher 54 by the rotation of the steering wheel 51, so that the ratchet teeth One side of the portion 332 is a ratchet tooth 213 meshing with the small aperture section 212, and the other side is a use state of the ratchet tooth 213 away from the small aperture section 212. -Refer to Figure 5 and Figure 6 for cooperation. When in use, the joint _ 315 of this set of joint 31 can be directly sleeved-bolt (not shown), or sleeved-adapter and then combined with other various workpieces, the The inner part of the joint portion 315 includes a fixed ring and a bolt or a work piece which are sleeved. When the sleeve is completed, the operation lever 22 can be tightened and loosened by two movements. “Small” can be flexibly used in the palm. If the space is not easy to move, you can use your fingers to directly dial the toggle part of the set of joints 31 to generate movements to avoid being blocked, and when the latching action is completed At that time, 9 M261325 users can directly press the ejector rod 52 to protrude to the center hole 3m to quickly disengage from the adapter 60 or bolt. y It is worth mentioning that 'in all latching operations, the bolt can be quickly turned to the appropriate tight state. The larger diameter operating lever 22 is needed to move it, and the speed will be slower, which is inconvenient. The new type can be loosened by using the operation lever, and then the toggle portion 314 can be quickly loosened, and the second movement portion 314 can be quickly tightened, and then the operation of the operation ^ ^ is used, so it is quite flexible and easy to use. .
