Embodiment Construction

[0046] First refer to the attached Figure 1-14 , a first embodiment of a ratchet wrench according to the invention comprises a handle 10 comprising a first end and a second end, each end comprising a lower face 11, 11', an inclined perforation 12, 12' and a cavity 15, 15, respectively ', the oblique perforation 12, 12' includes threaded parts 13, 13' for installing fixing screws 14, 14' to seal the oblique perforation 12, 12', and the cavity 15, 15' communicates with the oblique perforation 12, 12' ( Figure 5 , 7, and 12, 14). Extending from the first and second ends of the handle 10 are first and second heads 16, 16', respectively, including drive housings 17, 17' formed therein and communicating with the cavities 15, 15'. Each drive box 17, 17' includes a U-shaped portion 18, 18' ( Figure 5 and 12 ), which is formed at the top of the first end and the second end of the handle 10 and communicates with the cavity 15, 15'. A first ratchet mechanism and a second ratchet m...

Abstract

A ratchet wrench includes a first and a second drive members (21, 21') rotatably mounted in a first and a second heads (16, 16') extended from a first and a second ends of a handle 10. The first drivemember (21) includes a square inner periphery (35) adapted to slidably retain a drive shaft (36) including a 1 / 2'' drive fitting (45) and a 3 / 8' drive fitting (46) and the second drive member (21') includes a 1 / 4'' drive hexagonal bit holder (53) and 1-4'' drive fitting (54), for providing combined functions of ordinary ratchet wrenches for turning fasteners. A first and a second ratcheting mechanisms are mounted in the first and the second ends of the handle (10) for turning the first and the second drive members (21, 21'), by the handle (10).

Description

technical field [0001] The present invention relates to hand tools, and more particularly to a hex bit that includes a 1 / 4" drive and has a common ratchet profile at both ends of the handle while providing 1 / 2", 3 / 8" and 1 / 4" drive common A ratchet wrench with a combined function of the ratchet wrench. Background technique [0002] Ratchet wrenches are known and widely used for their ability to turn fasteners in a rapid manner. A common ratchet wrench includes a handle with a head extending from each end at each end of the handle. The first drive member is rotatably received in the head at one end of the handle and includes a 3 / 8" drive joint and a 1 / 2" drive joint respectively and integrally formed on the top and bottom ends thereof. A ratchet mechanical structure mounted in the head is mounted on the head and manipulated by a ring converter mounted on the head to control the direction of rotation of the first drive member. The second drive part is rotatably accommodated...
