Abstract
The utility model discloses a fast screw handle. The technical scheme is that the utility model consists of a handle, a coupling shaft and an outer sleeve. The utility model is characterized in that the outer sleeve is connected with the coupling shaft in a way of pin. The lower part of a round cavity in the outer sleeve is equipped with a clutch wheel. The center of the clutch wheel is equipped with a noncircular via hole. The circumference of the clutch wheel is equipped with a right angled gap. A pin is arranged in the right angled gap. An elastic clasp is arranged in the round cavity of the outer sleeve between the clutch wheel and the coupling shaft. A short angle side of the right angled gap is equipped with an elastic reed, which presses tightly on the pin. The utility model has the advantages of large torque, small idle rotation, single-hand operation and high efficiency.
Description
The utility model belongs to technical field of tools, especially relates to a kind of quick spiral shell cutter handle.
Our employed screwdriver mostly is the spiral shell cutter head greatly and is fixed on the handle at present, though this screwdriver can play the purpose that tightens the screw, but it is actual operate cumbersome, whenever tighten together, just need unclamp hand, adjust angle and could tighten process carrying out next step, so just reduced the speed of twist screws, reduced operating efficiency, though occurred a kind of just screwdriver of twist screws fast of hand that need not change now, but it is to utilize the screw thread rotation principle, need spur pivoted housing repeatedly, to drive spiral shell cutter head twist screws, this just needs bimanualness, so just make under some working environment and do not use this screwdriver, the moment of torsion of this screwdriver is less simultaneously, uses relatively effort.
The purpose of this utility model is to improve the deficiency of prior art and provides that a kind of moment of torsion is big, the idle running quick spiral shell cutter handle that angle is little, one hand can be operated, efficient is high.
The purpose of this utility model is to realize like this, a kind of quick spiral shell cutter handle, form by handle, connecting shaft and overcoat, be characterized in passing through the pin pin joint at overcoat and connecting shaft, the bottom is provided with castle wheel in the circular cavity of overcoat inside, and the castle wheel center is provided with non-circular through hole, has the right angle breach on the circumference of castle wheel, be provided with round pin in the right angle breach, be provided with snap ring in the circular cavity of the overcoat between castle wheel and connecting shaft.
In order further to realize the purpose of this utility model, can also be on the short right-angle side of right angle breach, to be provided with elastic spring to press round pin.
For the purpose that realizes preventing that tool heads from sliding, can also be that non-manhole can be oval-shaped, also can be polygonal.
Compared with the prior art the utility model has following distinguishing feature: the bottom is provided with castle wheel in the circular cavity of overcoat inside, the castle wheel center is provided with non-circular through hole, have the right angle breach on the circumference of castle wheel, be provided with round pin in the right angle breach, so just can guarantee castle wheel overcoat one-directional rotation simultaneously, overcoat then can independent two-way rotation, the short right-angle side of castle wheel right angle breach is provided with elastic spring and presses round pin, in the time of can guaranteeing that overcoat and castle wheel rotate simultaneously, round pin is in normal operating conditions, non-circular through hole can with supporting good combination of external spiral shell cutter head, guaranteed that external spiral shell cutter head can not slide separately at work.
The concrete structure of a kind of quick spiral shell cutter handle of the utility model is provided by the following drawings and embodiment.
Fig. 1 is a kind of quick spiral shell cutter handle arrangement schematic diagram of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is another A-A cutaway view of Fig. 1
Be described in further details below in conjunction with the concrete structure and the using method of drawings and Examples a kind of quick spiral shell cutter handle of the utility model.
Embodiment 1, a kind of quick spiral shell cutter handle, be in handle 8, to be fixed with connecting shaft 6, the handle 8 general polyester that adopt once are injection molded into circle, one end of irony connecting shaft 6 is connected with handle 8 when handle 8 injection mouldings simultaneously, the other end of irony connecting shaft 6 insert in overcoat 1 cavity and with overcoat 1 by pin 5 pin joints, cavity in the overcoat 1 is cylindrical, the lower end of overcoat 1 has through hole and communicates with overcoat 1 cavity, overcoat 1 cavity bottom is provided with cylindrical castle wheel 3, the excircle of castle wheel 3 contacts with the inner periphery of overcoat 1 cavity, on the excircle of castle wheel 3, have right angle breach 10, the right-angle side length difference of right angle breach 10, the opening direction difference of right angle breach 10, it changes just difference of tight direction, the opening of present embodiment right angle breach 10 down, overcoat 1 and castle wheel 3 can be rotated in the clockwise direction simultaneously, and overcoat 1 leaves independent rotation with castle wheel 3 in the counterclockwise direction, generally be used to tighten connector, the short right-angle side of right angle breach 10 is provided with elastic spring 7 and presses the round pin 2 that is positioned at right angle breach 10, the center of castle wheel 3 has the non-circular through hole 9 that runs through castle wheel 3, the through hole 9 of present embodiment is a hexagon, the through-hole diameter of the lower end of overcoat 1 is greater than the Breadth Maximum of through hole 9, in the cavity of the overcoat 1 of 6 of castle wheel 3 and connecting shafts, be provided with snap ring 4, be used to block the external tool head.
When using a kind of quick spiral shell cutter handle of the utility model, can be with the external tool head, revolve tool etc. as spiral shell cutter head, nut, insert in the snap ring 4 by the lower end through hole of overcoat 1, the non-circular through hole 9 of castle wheel 3, fix the external tool head, the external tool head is connected with wanting pine or tight connector, and reciprocal turning handle gets final product.
