Specific embodiment

Below in conjunction with the attached drawing in the utility model embodiment, the technical solution in the utility model embodiment is clearly and completely described.

As seen from FIG. 1-4, electric screwdriver fixing tool described in the utility model, including support rod 1, support arm 2, active chuck 3 and bearing block 4；The bearing block 4 is placed on the support rod 1, the bearing block 4 couples with one end of the support arm 2, and the bearing block 4 is able to drive the support arm 2 toward the movement of the both ends of the support rod 1 and the support arm 2 is driven to be rotated with the support rod 1 for center of rotation；The active chuck 3 couples with the rotation of the other end of the support arm 2, and the active chuck 3 can be rotated using the rotation connection place as center of rotation, and the active chuck 3 is for clamping electric screwdriver.

The course of work of present embodiment is as follows:

1, by 1 vertical display of support rod, and electric screwdriver is clamped with active chuck 3；

2, electric screwdriver is held, electric screwdriver is moved to the position for needing to lock screw, in which:

A, since bearing block 4 is able to drive support arm 2 toward the movement of the both ends of support rod 1, so user can hold electric screwdriver and move up and down；

It b, is that center of rotation is rotated since bearing block 4 is able to drive support arm 2 with support rod 1, so the first time that user can hold in electric screwdriver progress horizontal direction is circumferentially mobile；

C, since active chuck 3 can be rotated using rotating connection place as center of rotation, so user can hold second of circumferential movement in electric screwdriver progress horizontal direction.

Firstly, since the movement that present embodiment is able to carry out electric screwdriver vertically and horizontally guarantees going on smoothly for lock screw process so electric screwdriver can be arbitrarily moved to the position for needing to lock screw by user；It is circumferentially rotated twice secondly as present embodiment is able to carry out electric screwdriver, to expand the moving range of electric screwdriver horizontal direction；Further, when without using electric screwdriver, support arm 2 can be turned on one side, avoids occupying working space, to solve the problems, such as that existing auxiliary stand occupied space is big.

Preferred embodiments of the present invention are as illustrated in fig. 1 and 2, the support arm 2 includes lever arm 21 and telescopic arm 22, the lever arm 21 is connected and fixed with the bearing block 4, the telescopic arm 22 is actively coupled with the lever arm 21, the telescopic arm 22 can be moved back and forth along the axial direction of the lever arm 21, the active chuck 3 couples with the telescopic arm 22 rotation, and the active chuck 3 can follow the telescopic arm 22 toward and away from the lever arm 21.

To further increase electric screwdriver moving range in the horizontal direction, support arm 2 is set retractable structure by present embodiment, specific as follows:

1, when need to lock the product of screw apart from support rod 1 farther out when, telescopic rod is moved outward, so that the entirety of support arm 2 is elongated, active chuck 3 will be far from lever arm 21 at this time, and electric screwdriver is enabled to carry out lock screw operation to product apart from each other；

2, when the product for needing to lock screw is closer apart from support rod 1, telescopic rod is moved inside, so that the entirety of support arm 2 shortens, active chuck 3 will be close to lever arm 21 at this time, and electric screwdriver is enabled to carry out lock screw operation at a distance of closer product.

So present embodiment can increase the moving range of electric screwdriver in the horizontal direction again, to meet the service condition of the overwhelming majority.

Preferred embodiments of the present invention are as illustrated in fig. 1 and 2, and the opposite two sides of the lever arm 21 are equipped with the first track groove 211, and two first track grooves 211 are along the axial direction arrangement of the lever arm 21；The telescopic arm 22 is equipped with the first at least a pair of directive wheel 231, each pair of first directive wheel 231 is respectively embedded into two first track grooves 211, and the telescopic arm 22 can be moved back and forth by first directive wheel 231 along the track of first track groove 211.

For the stability for improving 22 moving process of telescopic arm, present embodiment is linked using the first track groove 211 and the cooperation of the first directive wheel 231, specific as follows:

1, since the first track groove 211 is along the axial direction arrangement of lever arm 21, so limitation telescopic arm 22 is only capable of moving back and forth along the track of the first track groove 211 after the first directive wheel 231 is embedded in the first track groove 211；

2, in 22 moving process of telescopic arm, the first directive wheel 231 will be in rolling contact with the first track groove 211, and contact area is small, can guarantee the smooth stabilization in 22 moving process of telescopic arm；

3, the first directive wheel 231 can be multipair, but the first excessive directive wheel 231 is arranged and will increase not Necessary production cost, it is advantageous to set 1~3 pair for the first directive wheel 231.
