DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0020] The specific embodiment of the utility model provides a screw clamping tool, combined with the attached Figure 1 As shown, it mainly includes a mounting frame 1, a tightening rod 2 and a reset member 3, wherein:

[0021] One end of the mounting frame 1 is a clamping head 4, and the other end is a sliding connection part 5. The clamping head 4 has a notch 6 for setting a screw, and the screw is set on the clamping head 4 through the notch 6;

[0022] The clamping rod 2 is slidably connected to the sliding connection part 5, one end of the reset member 3 is connected to the sliding connection part 5 and the other end is connected to the clamping rod 2, the reset member 3 has a force to push the clamping rod 2 to tighten the screw to the tightening head 4, and the pushing force of the reset member 3 makes the clamping rod 2 tighten the screw to the tightening head 4, so that the clamping effect of the screw can be achieved to prevent the screw from falling during installation;

[0023] Since the clamping rod 2 is relatively slidably connected to the sliding connection part 5, the clamping rod 2 can reciprocate toward the clamping head 4 and away from the clamping head 4. When placing the screw, it is only necessary to operate the mounting frame 1 and the clamping rod 2 to move relative to each other so that the clamping rod 2 moves in the direction away from the clamping head 4. At this time, the position of the clamping head 4 can be vacated, and the screw can be placed in the notch 6. At this time, the mounting frame 1 and the clamping rod 2 are released, and the clamping rod 2 can tighten the screw to the clamping head 4 under the action of the reset member 3.

[0024] Specifically, one end of the tightening head 4 that tightens the screw has a limiting body 7 that matches the screw. The cooperation between the limiting body 7 and the screw can limit the rotation of the screw relative to the limiting body 7. The limiting body 7 can be a cross head screwdriver bit that matches the cross head screw; it can also be a slotted screwdriver bit that matches the slotted screw; of course, it can also be other screwdriver bits such as hexagonal internal and external hexagonal screws. The setting of the limiting body 7 is intended to achieve limiting the relative rotation between the screw and the limiting body 7, thereby smoothly transmitting the force to the screw to complete the initial tightening of the screw.

[0025] In some embodiments, the clamping head 4 can be a sheet-like body, and the peripheral side of the sheet-like body is connected to the sliding connection part 5 through a first connecting body 8. The first connecting body 8 can be a connecting sheet body structure with a connecting rod and an arc-shaped surface, which is intended to achieve the connection between the clamping head 4 and the sliding connection part 5. The notch 6 in the present application is composed of a mounting hole in the middle of the sheet-like body and an extension opening extending from the mounting hole to the edge of the clamping head 4. When the screw is placed, it is inserted from the extension opening until it moves to the mounting hole and stops. The clamping rod 2 is opposite to the mounting hole, and the clamping rod 2 can extend from the mounting hole to the side of the clamping head 4 away from the sliding connection part 5.

[0026] In some embodiments, the sliding connection portion 5 includes a limiting plate 9, a second connecting body 10 and a clamping plate 11. One end of the second connecting body 10 is connected to the limiting plate 9, and the other end is connected to the clamping plate 11. The second connecting body 10 can be a rod-shaped body, a cylindrical body, a sheet-shaped body, etc., in order to achieve the connection between the limiting plate 9 and the clamping plate 11. Both the limiting plate 9 and the clamping plate 11 are provided with a through hole 12 for the clamping rod 2 to pass through. The clamping rod 2 can be slidably penetrated into the through hole. A limiting portion 13 is provided on the clamping rod 2, and the limiting portion 13 is located between the limiting plate 9 and the clamping plate 11. One end of the reset member 3 is connected to the limiting portion 13, and the other end is connected to the clamping plate 11. The reset member 3 has a tendency force to push the limiting portion 13 and the clamping plate 11 away from each other, and indirectly has a tendency force to push the clamping rod 2 to move toward the direction of the clamping rod 2.

[0027] In some embodiments, the axes of the through holes on the limiting piece 9 and the abutting piece 11 and the local mounting holes of the notch 6 are coaxial.

[0028] In some embodiments, the reset member 3 may be a spring, which is sleeved on the abutting rod 2 , one end of the spring abuts against the limiting portion 13 , and the other end abuts against the abutting sheet 11 , and the spring is in a compressed state.

[0029] In a specific embodiment of the present application, the abutting rod 2 includes a release state, a locking state and a screwing state:

[0030] in:

[0031] The release state is the state when the screw is placed in the notch 6 or is released from the notch 6. Figure 1 As shown in , by pushing the mounting frame 1 to the left, the clamping rod 2 can be moved away from the clamping head 4, and the screw can be placed in the notch 6 or the screw can be disengaged from the notch 6. When the screw is placed in the notch 6, the mounting frame 1 can be pressed to the right to be released, and after the initial screwing is completed, the clamping rod 2 can be stretched to achieve the movement of the clamping rod 2 relative to the mounting frame 1.

[0032] The locking state is the state in which the screw is tightened against the tightening head 4. At this time, the screw is located in the notch 6, the limiting body 7 of the tightening rod 2 is pressed against the screw, and the rotation of the screw relative to the tightening rod 2 is limited by the limiting body 7. At this time, the initial tightening can be achieved by screwing the tightening rod 2 to drive the rotation of the screw.

[0033] In the screwing state, that is, the screw is in place and has come out of the notch 6, the reset member 3 pushes the clamping rod 2 to move to the initial position. In the initial position, the limit body 7 of the clamping rod 2 is located on the left side of the clamping head 4. At this time, this screw clamping tool can be used to realize the screwing effect of the screwdriver, and the screw tightening work is completed by secondary tightening.

[0034] A screwdriver is also provided in a specific embodiment of the present application, including a handle portion and the above-mentioned screw clamping tool, wherein the handle portion is arranged at an end of the clamping rod 2 away from the mounting frame 1 .

[0035] Specifically, the handle is a grip, and the grip sleeve is arranged on the end of the clamping rod 2 away from the mounting frame 1. The grip is provided with anti-slip grooves for easy grasping and use.

[0036] Specifically, the handle may also be an electric handle, and the end of the pressing rod 2 away from the mounting frame 1 is designed to be a square head for use with the electric handle.
