In the above embodiment of the present invention, the screwdriver 2 is inserted into the groove 1211 of the hem 121 at the end of the clamping arm 12 far away from the main structure 11 through the through hole 131 of the fixing member 13 and the second opening 112 at the bottom of the main structure 11 from the first opening 111 at the top of the main structure 11, and the screwdriver 2 is locked by the fixing member 13, so that the screwdriver 2 and the clamp provided by the present invention form a whole; then, the screw 3, the flat pad (not shown) and the elastic pad (not shown) are placed at the folded edge 121 and are abutted and fixed with the head end of the screwdriver 2; therefore, the screw 3 can be smoothly screwed into the screw hole without the help of an external tool, the problem that the screw 3, the flat pad and the elastic pad are easy to fall off in the installation process when mechanical equipment is connected and fixed is solved, and the whole equipment is lifted to shake due to the falling of the screw 3, the flat pad and the elastic pad so as to find the falling screw 3, the flat pad and the elastic pad; the installation space of the mechanical equipment can not be led in redundant objects, the equipment can not be damaged, and the installation efficiency is improved.

Specifically, when the space for installing the screw 3 is narrow and the screw 3 or the screw 3 with the flat pad and the elastic pad is not easily installed in the screw hole, the screwdriver 2 is moved to one side of the main structure 11 by controlling the relative movement of the screwdriver 2, the main structure 11 and the clamping arm 12, so that the screwdriver 2 is separated from the flange 121, the flat pad and the elastic pad are placed on the flange 121, the head end of the screw 3 sequentially penetrates through the elastic pad, the flat pad and the grooves 1211 of the two flanges, and then the relative movement of the screwdriver 2, the main structure 11 and the clamping arm 12 is controlled, as shown in fig. 2, the head end of the screwdriver 2 is abutted against the tail end of the screw 3, so that the screw 3, the flat pad and the elastic pad are connected with the screwdriver 2 into a whole; and controlling the handle of the screwdriver 2 to install the screw 3 into the screw hole, opening the two clamping arms 12 when the screw 3 is partially screwed into the screw hole and is separated from the screwdriver 2 and the screw 3 does not fall off, separating the screwdriver 2 from the screw 3, and installing the screw 3 which does not enter the screw hole into the screw hole.

Further, due to the arrangement of the flange upper groove 1211, the screw 3 can penetrate through the flange 121, so that the tail end of the screw 3 is abutted and fixed with the screwdriver 2, and the screw 3 is installed; in addition, as shown in fig. 3, when the screw 3 is partially screwed into the screw hole, the head end of the screwdriver 2 may pass through the groove 1211 to the outside of the flange 121, so that the remaining portion of the screw 3 is screwed into the screw hole.

It should be noted that, when the screwdriver 2 is connected and fixed with the fixture, the head end of the screwdriver 2 passes through the groove 1211 of the folded edge 121, and the distance between the end surface of the head end of the screwdriver 2 and the folded edge 121 is 0.5 cm to 1.5 cm, which may be set according to actual conditions; thus, when the screw 3 is partially screwed into the screw hole and the screw 3 is separated from the driver 2, as shown in fig. 4, the head end of the driver 2 can be restored to the original position, so that the driver 2 can be used to mount the part of the screw 3 which is not screwed into the screw hole.

In one embodiment, as shown in fig. 5, the through hole 131 penetrates through the lower surface of the fixing member 13 from the upper surface of the fixing member 13, so that the screwdriver 2 passes through the through hole 131 to the folding groove 1211 of the clamping arm 12; two locking pieces 15 are arranged on two opposite side walls of the through hole 131; the locking member 15 is configured for locking between the screwdriver 2 and the fixation member 13. Like this, could fix screwdriver 2, make it can not remove for anchor clamps, and then make screwdriver 2 be connected as a whole with whole anchor clamps, realize with screw 3 butt to in screwing in screw hole with screw 3.

In an embodiment, the locking member 15 is inserted into the through hole 131 from the outside of the sidewall of the fixing member 13, the locking member 15 includes an end (not shown) for contacting and fixing with the screwdriver 2, and the locking member 15 is screwed with the fixing member 13. Here, the length of the locker 15 in the axial direction thereof is greater than the thickness of the sidewall of the holder 13, so that the locker 15 can be inserted into the through-hole 131 from the outside of the sidewall of the holder 13 and the end thereof can be brought into contact with the driver 2 to fix it; retaining member 15 with spiro union complex mode between the mounting 13 for the length that retaining member 15 got into mounting 13 can be adjusted, and can keep fixed connection with mounting 13 all the time, also can not separate with mounting 13 under natural state.

In one embodiment, the through hole 131 includes: a major axis side and a minor axis side; the locking member 15 is located on the side of the minor axis. The head end of the screwdriver 2 comprises a cross-shaped screwdriver head and a straight screwdriver head; for the straight-line-shaped screwdriver head, because the width of the straight-line-shaped screwdriver head in the straight-line direction is larger than the radial width of the rod body of the screwdriver 2, the arrangement of the side part of the long shaft and the side part of the short shaft can ensure that the screwdriver 2 of the straight-line-shaped screwdriver head can also smoothly pass through the through hole 131 of the fixing part 13; specifically, when the screwdriver 2 with the linear bit passes through the through hole 131 of the fixing member 13, the linear direction of the linear bit of the screwdriver 2 passes through the through hole 131 in parallel along the long axis side; because the thickness of the side wall of the fixing part 13 corresponding to the short shaft side part is larger than that of the fixing part 13 corresponding to the long shaft side part, the length of screwing the locking part 15 into the fixing part 13 when the locking part 15 is arranged on the short shaft side part is longer, and the fixing degree of the screwdriver 2 is more stable compared with the way that the locking part 15 is arranged on the long shaft side part; further, the fixing member 13 includes a locking hole 132 disposed to cooperate with the locking member 15; the locking member 15 passes through the locking hole 132 and the end thereof to lock the screwdriver 2; here, the locking hole 132 may be a threaded hole, and the locker 15 may be a bolt; the head end of the bolt penetrates through the threaded hole to fix the rod body of the screwdriver 2; of course, under the condition that does not influence the utility model discloses result of use, retaining member 15 can also be other parts, and the screw hole also can be other locking holes that use with retaining member 15 cooperation.

In one embodiment, the main body 11 includes a sidewall portion, and the sidewall portion includes two chute holes 113 oppositely disposed along an axial direction of the main body 11; the end of the locking element 15 facing away from the fixing element 13 is located outside the slideway opening 113. After the screwdriver 2 is fixedly connected with the fixing piece 13, one end of the locking piece 15 slides on the slide way hole 113 while the screwdriver 2 and the fixing piece 13 move relative to the main structure 11; the arrangement in which the end of the locking member 15 facing away from the fixing member 13 is located outside the slide hole 113 makes it possible to restrict the locking member 15 from moving further when the locking member 15 slides to both ends of the slide hole 113.

Further, the radial width of the end of the locking member 15 facing away from the fixing member 13 is larger than the width of the sliding channel hole 113, so that the locking member 15 is prevented from entering the inner cavity of the main body structure 11 through the sliding channel hole 113; of course, in the actual using process, as long as the using effect of the clamp provided by the present invention is not affected, the radial width of the end of the locking member 15 departing from the fixing member 13 may not be greater than the width of the chute hole 113.

In one embodiment, the top of the main body structure 11 includes a limiting edge 114, and the elastic element 14 is fixed between the limiting edge 114 and the upper surface of the fixing element 13. Thus, after the screwdriver 2 is fixedly connected with the fixing part 13 through the locking part 15, a user pulls the screwdriver 2, the screwdriver 2 drives the fixing part 13 to move, the fixing part 13 drives the locking part 15 to move relative to the slide way hole 113 and pushes the elastic part 14 to compress the elastic part, after the user loosens the screwdriver 2, under the elastic action of the elastic part 14, the fixing part 13 and the screwdriver 2 both move towards the direction of the folded edge 121 of the clamping arm 12, and because the screw 3, the flat pad and the elastic pad are already placed on the folded edge 121 at the moment, after the screwdriver 2 is loosened, the head end of the screwdriver 2 can be in abutting contact with the tail end of the screw 3, so that the screwdriver 2, the clamp, the flat pad and the elastic pad are integrated. Here, the elastic member 14 may be a spring, and of course, other elastic members may be used without affecting the using effect of the present invention.

In an embodiment, the distance between two clamping arms 12 gradually decreases from the end of the clamping arm 12 close to the main structure 11 to the end far away from the main structure 11. The radial width of the main structure 11 is greater than that of the screw 3, and with such a design, after the screw 3 is placed in the groove 1211 of the folded edge 121 of the clamping arm 12, the supporting strength of the clamping arm 12 is stronger in the process of mounting the screw 3; in addition, when the screw hole is in the interior of the mechanical device and the installation space is narrow, a part of the clamping arm close to the folded edge 121 can enter the installation space, so that the screw can be smoothly screwed into the screw hole.

In one embodiment, as shown in fig. 2, the bottom of the main structure 11 is open, the clamping arms 12 extend from the edge of the open, and the clamping arms 12 and the main structure 11 are an integral structure. Based on the integrated design of the clamping arm 12 and the main body structure 11, in the technical scheme, the open edge can also be equal to the open edge.

Obviously, the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention, and it is obvious for those skilled in the art to make other variations or changes based on the above descriptions, and all the embodiments cannot be exhausted here, and all the obvious variations or changes that belong to the technical solutions of the present invention are still in the protection scope of the present invention.
