Abstract
The utility model relates to a hardware tool, in particular to a sleeve head-grasping type screwdriver which comprises a handle, a main rod, a push-pull ring, a knife head, a sleeve, a claw head and deformation joints, wherein the push-pull ring is a hard plastic ring and is arranged on the upper end of the sleeve, the lower end of the sleeve is the claw head, the claw head is in a shape of a truncated cone, three longitudinal deformation joints are arranged on the side surface of the claw head and uniformly divide the claw head into three parts, and the sleeve is sleeved on the main rod and forms a movable matching relationship with the main rod. With the adoption of the utility model, screws made of all materials can be fixed at the end of the screwdriver, and fixation can be timely released; and compared with the traditional screwdriver, the sleeve head-grasping type screwdriver can be more adapted to the installation and the disassembly of a screw at a narrow part which can not be touched by hands and has the advantages of convenience in use and wide application range.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, particularly relates to a kind of sleeve pipe grappling fixture formula screwdriver.
Background technology
The narrow positions that can't touch staff with the existing screwdriver very difficulty of nail of tightening up a screw.Some screwdriver end has magnetic, screw can be adsorbed on its termination, but powerless for the screw of non-ferrous material such as stainless steel.
The utility model content
The utility model provides a kind of screw fixings also can be removed fixing sleeve pipe grappling fixture formula screwdriver in driver tip in good time for solving the deficiencies in the prior art.
The scheme that solves the utility model technical problem is: sleeve pipe grappling fixture formula screwdriver is made of handle, mobile jib, push-and-pull ring, cutter head, sleeve pipe, pawl head and movement joint.The push-and-pull ring is the rigid plastics annulus, and push-and-pull ring, sleeve pipe, pawl head are as a whole, and the upper end of sleeve pipe is the push-and-pull ring, and the lower end of sleeve pipe is the pawl head, and the pawl head is a truncated cone-shaped, the side of pawl head have three longitudinally movement joint the pawl head is divided into three parts.Sleeve pipe is placed on the mobile jib and with mobile jib and is in active relationship.The upper end of mobile jib is in the handle and is bonding with handle, and the lower end of mobile jib is the cutter head of cross or yi word pattern.During use, earlier the butt end of screw is filled in the end opening of pawl head, the pawl head is pushed by it, and three movement joints broaden, and screw is clamped under the flexible effect of pawl head self.When with screwdriver screw being delivered to correct position, only need the direction of push-and-pull hoop handle is drawn, in the groove of jacking end, screw promptly breaks away from the end opening of pawl head.Adopt such scheme, can reach following effect:
Because the utility model can also can in good time be removed fixing in driver tip the screw fixings of all materials, compare with existing screwdriver, more can adapt to the installation and removal of the screw of the narrow positions that staff can't touch, have advantage easy to use, widely applicable.
