Description

Quick labor-saving screwdriver capable of being operated by single hand

Technical Field

The utility model relates to a manual hardware and tools's technical field, concretely relates to but quick laborsaving utensil that revolves of one-hand operation.

Background

The screwdriver is a common tool which holds a handle to rotate to drive a screwdriver rod to apply torque to a screw through a screwdriver head so as to load and unload the screw. The existing screwdriver is generally characterized in that a handle is connected with a straight shank screwdriver rod, and the head end of the straight shank screwdriver rod can be connected with screwdriver heads in various shapes.

In the prior art, the screwdriver is a straight shank screwdriver, the force arm of the screwdriver is short, an operator wants to dismount or screw down an over-tightened screw, and the screwdriver with the straight shank has short rotation stroke and unsatisfactory mounting and dismounting speed.

Therefore, a rapid labor-saving screwdriver capable of being operated by one hand is designed.

Disclosure of Invention

For solving the problem, the utility model provides a but quick laborsaving utensil of screwing up of one-hand operation, if the screw needs to be screwed up in the screw in or the loading process that meets the screw in tension in dismantling the in-process, can use the thumb to break off with the fingers and thumb and move supplementary application of force structure and can easily accomplish above-mentioned task, and hold the loading and unloading work that rotatory handle rotates the completion screw that the wrist can be quick gently.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a quick labor-saving screwdriver capable of being operated by one hand comprises a screwdriver rod working head, a force application screwdriver rod, a shaft sleeve, a bearing ball and a holding handle, wherein a groove is formed in the head of the screwdriver rod working head, a magnet is arranged at the bottom of the groove, various screwdriver heads can be respectively inserted into the groove, the outer surface of each screwdriver head and the inner surface of the groove are hexagonal prism-shaped, and the screwdriver heads and the groove can be matched with each other and fixed by magnetic force. The handle is characterized in that a cavity is formed in the holding handle, a shaft sleeve is arranged in the cavity, the shaft sleeve and the cavity are tightly connected and matched with each other, the bottom of the force application batch rod penetrates through the shaft sleeve, a gap exists between the force application batch rod and the shaft sleeve, and the force application batch rod can rotate in the shaft sleeve.

Further, the axle sleeve bottom with be equipped with the bearing ball between the cavity inner wall, the pole bottom is criticized in the application of force fluted and with the contact of bearing ball, through setting up the bearing ball, can make the pole is criticized in the application of force sleeve inside fixed position and be convenient for more rotate, the user only need rotate the wrist gently, the dismantlement loading work of completion screw that can be quick.

Furthermore, an auxiliary force application structure is arranged at a position, close to the hand-held position, of the force application batch rod, an included angle of 30-60 degrees is formed between the auxiliary force application structure and the force application batch rod, the included angle is 4-5cm away from the holding handle, and when a user holds the holding handle tightly, the user can stretch out a thumb to pull the auxiliary force application structure to complete auxiliary force application work, so that over-tightened screws can be removed or tightened screws can be installed.

Compared with the prior art, this can one-hand operation's quick laborsaving utensil of rotating soon possesses following beneficial effect:

1. this but quick laborsaving utensil that revolves of one-hand operation through axle sleeve and bearing ball for the pole is criticized in the application of force and is convenient for more rotate inside the sleeve, owing to criticize pole working head, the pole is criticized in the application of force and grip handle three rotation axis coaxial, so grip the handle through holding, rotate the wrist gently, can be quick accomplish the loading and unloading work of screw.

2. This laborsaving utensil of screwing up that can singlehanded operation, when meetting the screw in overtightened or need screw up, can hold the handle of gripping, break off with the thumb and assist the application of force structure, drive and criticize the pole and rotate, can be light unload or screw up the screw.

Description of the drawings:

FIG. 1 is a block diagram of the present invention;

fig. 2 is a schematic rotation diagram of the present invention.

The labels in the figure are: 1. the device comprises a batch rod working head, 2, a force application batch rod, 2-1, an auxiliary force application structure, 3, a shaft sleeve, 4, a bearing ball and 5, a holding handle.

The specific implementation mode is as follows:

as shown in fig. 1 to 2, a rapid labor-saving screwdriver capable of being operated by one hand comprises a screwdriver rod working head 1, a force application screwdriver rod 2, a shaft sleeve 3, a bearing ball 4 and a holding handle 5, wherein a groove is formed in the upper end of the screwdriver rod working head 1, the screwdriver rod can be connected with various screwdriver heads and fixed by magnetic force, the lower end of the screwdriver rod working head 1 is tightly connected with the force application screwdriver rod 2, an auxiliary force application structure 2-1 is arranged at a part, close to the holding handle 5, of the force application screwdriver rod 2, a cavity is formed in the holding handle 5, the bottom of the cavity is a V-shaped groove, the bearing ball 4 is placed in the V-shaped groove, the shaft sleeve 3 is arranged in the cavity, the cavity is tightly connected with the shaft sleeve 3, and the bottom of the force application screwdriver rod 2 penetrates through the shaft sleeve 3 and is in contact with the bearing ball 4.
