Embodiment 1

[0034] like Figure 1-10 As shown, the adjustable one-way ratchet wrench includes a wrench head 1, the wrench head 1 is connected with a handle 2, the wrench head 1 has a torque output cylinder 3, and the torque output cylinder 3 is connected with the ratchet 41 in the wrench head 1 through the transmission mechanism 4 , the ratchet 41 cooperates with a number of ratchets 42 that are rotatably installed in the wrench head 1, and the wrench head 1 is provided with a sliding block 43 surrounded by the ratchet 41. The sliding block 43 is arc-shaped and a push block 44 is fixed on the outside and the push block 44 Extending to the outside of the wrench head 1, the inner side of the sliding block 43 and the tail of the pawl 42 are rotationally connected by an arc-shaped linkage piece 45. A sliding limit mechanism 5 is arranged between the sliding block 43 and the wrench head 1, and the outer side of the sliding block 43 is connected to the A return spring 46 is connected between th...

Embodiment 2

[0045] like Figure 11-12 As shown, the structure, principle and implementation steps of this embodiment are similar to those of Embodiment 1, the difference is that the accessory 7 in this embodiment is an adapter 73, and the lower end of the adapter 73 is provided with a joint that fits the lower end of the wrench head 1. The limit disc 74, the center of the limit disc 74 is provided with an adapter 75, and the adapter 75 and the extension rod 76 are fixedly plugged together. The adapter 73 cooperates with the extension rod 76, and is suitable for threaded installation in a narrow space where the wrench head 1 cannot extend into. It is similar to the nut sleeve 71, and an extension rod 76 of suitable specifications can be selected according to actual needs.

Embodiment 3

[0047] like Figure 13-15 As shown, the structure, principle and implementation steps of this embodiment are similar to those of Embodiment 1, the difference is that in this embodiment, the accessory 7 is an adjustment base 77, and the inner side of the adjustment base 77 is a number of parts opposite to the side of the threaded fastener. The end surface 78 of the end surface 78 is provided with an installation groove 79 extending to the lower end of the adjustment base 77, and a clamping plate 791 is installed in the installation groove 79, and one end of the clamping plate 791 is rotationally connected with the inside of the installation groove 79 and the other end is provided with a clamp Tight block 792, the clamping block 792 is columnar and the central axis is parallel to the end face 78, the lower end of the adjustment base 77 is supported by the vertical plate 793 and connected to the limit ring 794, the clamping block 792 is distributed between the vertical plates 793,...

Abstract

The invention provides an adjustable one-way ratchet wrench, which solves the problem that the ratchet wrench is easily damaged due to excessive torque. The transmission mechanism is connected with the ratchet in the wrench head, and the ratchet pawl cooperates. A sliding block is set inside the wrench head. A push block is fixed on the outside of the sliding block. There is a sliding limit mechanism between the wrench head and the outer side of the sliding block and the inner wall of the wrench head. The transmission gear in the transmission mechanism has an inner ring and an outer ring. A safety plate is inserted between the opposite socket slots, and a torque indicator is distributed above the transmission gear. The invention has the advantages of good component protection effect, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of ratchet wrench, in particular to an adjustable one-way ratchet wrench. Background technique [0002] Ratchet wrench is a manual screw tightening tool, single head, double head multi-standard movable handle ratchet ring wrench. It is connected by the main torx sleeve of different specifications and sizes and the secondary torx sleeve through the female key and male key of the hinge key. Because a torx bush has two specifications of torx-shaped through holes, it can be used for the tightness of screws of two specifications, thereby expanding the use range and saving raw materials and working hours. The adjustable wrench can easily adjust the wrench use angle. The wrench is used for loosening and tightening operations of screws, and has the characteristics of strong applicability, convenient use and low manufacturing cost. However, in the actual use process, improper use by the operator and excessive torq...
