Abstract
Abstract This disclosure concerns a tool fixing mechanism including a hollow grip and a resilient clip body. The grip has a front end and a rear end. The front end is formed with a slot, while the rear end is formed with a cross-shaped socket. Two windows are respectively formed on the top and bottom walls of the rear end of the grip. The resilient clip body is located in the cross-shaped socket of the grip. The resilient clip body is formed with two lugs extending out of the windows of the grip. Therefore, if a user depresses the lugs, the resilient clip body is closed or stretched open so as to fixedly latch or release a tool inserted in the slot of the front end of the grip.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
185 words
A tool fixing mechanism comprising: (a) a hollow grip, said grip having an elliptic cross-section, a front end and a rear end, the front end being formed with a slot, while the rear end being formed with a cross-shaped socket, two windows being respectively formed on the top and bottom walls of the rear end of the grip in the short axis direction of said elliptic cross-section; and (b) a resilient clip body, said resilient clip body being located in the cross-shaped socket of the grip, consisting of an upper plate body, a lower plate body, a fixing shaft and a resilient member, the fixing shaft being connected at the middle portions of the upper and lower plate bodies and disposed at the pivot portion via the resilient member, the opposite inner sides of the front ends of the upper and lower plate bodies being respectively formed with two reverse hooks inclined toward the rear ends, the opposite outer sides of the rear ends of the upper and lower plate bodies being respectively formed with two lugs extending out of the windows of the grip.
Claim 2
Dependent Claim
185 words
A tool fixing mechanism comprising: (a) a hollow grip, said grip having an elliptic cross-section, a front end and a rear end, the front end being formed with a slot, while the rear end being formed with a cross-shaped socket, two windows being respectively formed on the top and bottom walls of the rear end of the grip in the short axis direction of said elliptic cross-section; and (b) a resilient clip body, said resilient clip body being located in the cross-shaped socket of the grip, consisting of an upper plate body, a lower plate body, a fixing shaft and a resilient member, the fixing shaft being connected at the middle portions of the upper and lower plate bodies and disposed at the pivot portion via the resilient member, the opposite inner sides of the front ends of the upper and lower plate bodies being respectively formed with two reverse hooks inclined toward the rear ends, the opposite outer sides of the rear ends of the upper and lower plate bodies being respectively formed with two lugs extending out of the windows of the grip.
Claim 3
Dependent Claim
124 words
A tool fixing mechanism as claimed in claim 1, wherein the resilient member is a V-shaped steel plate with a notch, each free end of the steel plate being formed with a convex strip on an inner side, a through hole being formed between the middle portion and the rear end of each of the upper and lower-plate bodies, the two free ends of the resilient member being respectively passed through the through holes of the upper and lower plate bodies with the convex strips engaged with the recesses formed on outer sides of the front ends of the upper and lower plate bodies, whereby the opening of the resilient member is faced to the front ends of the upper and lower plate bodies.
Claim 4
Dependent Claim
20 words
A tool fixing mechanism as claimed in claim 1, wherein each reverse hook is disposed with a back slope face.
