still including setting up the adjustment mechanism on outer casing 1 surface, adjustment mechanism includes swing arm 13, the surface of outer casing 1 is inserted through bearing equidistance symmetry and is equipped with swing arm 13, 13 opposite side equidistance symmetry of the swing arm on outer casing 1 surface are inserted and are equipped with loop bar 14, the threaded bush that passes through of loop bar 14 is established on the surface of swing arm 13, loop bar 14 arranges the outside one end of outer casing 1 in and all is the spheroid, loop bar 14 arranges the outside cover of outer casing 1 in and is equipped with universal ball seat 15, one side that loop bar 14 was kept away from to universal ball seat 15 all supports touch panel 16 fixed connection with elasticity.

In this embodiment, the screwdriver bits 11 are provided with a plurality of groups, the bottom ends of the screwdriver bits are different in size so as to be suitable for screws of different sizes, when a screw is located on a wall surface and a concave corner position of a bottom surface, a user can select the indicated screwdriver bit 11 according to the size of the screw, the user pulls the inserted rod 9 to enable the inserted rod 9 to slide in the fastener 8, so that the screwdriver bit 11 on the surface of the inserted rod 9 is stretched and deformed along with the movement of the inserted rod 9 and simultaneously enables the top end of the inserted rod 9 to extend out of a bottom jack of the outer shell 1, the user drives the fastener 8 to slide towards one side of the outer shell 1 by pulling the inserted rod 9 transversely, at the moment, the two groups of limiting plates 7 are far away from each other, the user can insert the selected screwdriver bit 11 into a bottom opening of the transmission rod 5 to a limit position, then further push the inserted rod 9 to bring the fastener 8 to approach the outer shell 1, when the fastener 8 is moved to the limit position by transmission, the user can loosen the inserted rod 9, the inserted rod 9 is elastically reset by the reset spring, so that the screw is inserted rod 9 is inserted into the limiting rod 9, the limiting plate 11 is locked again, and the screw is pressed against the limiting plate 11, and the limiting plate 11 abuts against the outer shell, and the limiting plate 12 is pressed against the screw bit 9;

at the moment, a user can insert the end of a screwdriver bit 11 into an exposed end opening of a screw at the mounting position on the surface of the electromechanical equipment, and then the user rotates the rotary rods 13 in sequence, the rotary rods 13 drive the loop bars 14 to extend out of the outer shell 1 through the action of threads, so that the universal ball seats 15 connected with the ends of the loop bars 14 drive the elastic touch panels 16 to gradually adhere to the inside wall surface and the ground surface of the mounting position of the screw, in the process, the universal ball seats 15 move on the spherical end surface of the loop bars 14, the transmission effect of the rotation of the rotary rods 13 on the loop bars 14 is adapted by means of the elastic deformation of the elastic touch panels 16, and finally the user rotates the rotary rods 13 in sequence to enable the elastic touch panels 16 to adhere to the wall surface and the ground surface, so that the screws close to the inside wall surface are arranged in sequence to be mounted and dismounted;

then a user holds the handle 3, rotates to make a circular motion to drive the rotating rod 2 to rotate, the rotating rod 2 synchronously rotates through the bevel gear 6 connected with the end of the rotating rod to drive the transmission rod 5 to rotate, and the transmission rod 5 rotates to carry the screwdriver head 11 connected with the end of the transmission rod to rotate together, so that a rotating effect is generated on the screw, and the screw can be used for mounting and dismounting the screw;

it should be noted that the outer casing 1 and other components in the drawings in the specification are not standard sizes, and in the implementation of the technical scheme, a user can coordinate the sizes of the components of the device according to the use scene of the user to achieve the purpose of adapting to the use requirement.

As shown in fig. 1, one end of the rotating rod 2 is connected with a handle 3 through a bearing, and anti-skid grains are arranged on the surfaces of the outer shell 1 and the handle 3.

Can make when the user need rotate bull stick 2 through this setting, the user accessible is held handle 3 and is rotated transmission bull stick 2 rotatory, because handle 3 is connected through the bearing with bull stick 2, can be so that the rotation of bull stick 2 is eliminated by the bearing that bull stick 2 and handle 3 link to each other, when avoiding bull stick 2, handle 3 to rotate, handle 3 causes the friction at user's centre of hand corotation.

As shown in fig. 3, the cross section of the opening at the bottom end of the transmission rod 5 for the screwdriver bit 11 to be inserted is hexagonal, and the edge of the opening at the bottom end of the transmission rod 5 for the screwdriver bit 11 to be inserted is arc-shaped.

So set up and need not accurate alignment when can making screwdriver bit 11 insert the transfer line 5 bottom, bring the guide effect of certain degree through the convex setting of hexagon and trompil edges and corners to insert that screwdriver bit 11 is more swift.

As shown in fig. 5, a spherical groove is formed on the surface of the universal ball seat 15, the universal ball seat 15 is sleeved on the end surface of the loop bar 14 through the spherical groove formed on the surface, and the surface of the elastic contact plate 16 is uniformly glued with the bumps 17.

The arrangement of the convex block 17 can enhance the friction force generated by the contact surface of the elastic contact plate 16 and the wall surface and the ground surface, so that the device is more stable in use.
