DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0037] See also Figures 1 to 11 The present invention provides a technical solution: a multi-purpose electric tool socket device, a socket 1, a mounting groove connected to the electric tool is provided on the left side of the socket 1, an opening is provided on the other side of the socket 1, a movable plate 2 is provided inside the socket 1, and the movable plate 2 is horizontally slidably connected to the socket 1;

[0038] The sleeve 1 is installed on the electric tool through the structure of the installation groove, so that the electric workpiece can drive the sleeve 1 to rotate, so as to install and remove the screw or nut.

[0039] A rotating gear 26 is installed on one side of the movable plate 2 away from the connection between the sleeve 1 and the electric tool, and the axis of the rotating gear 26 is rotatably connected to the movable plate 2 via a shaft;

[0040] The rotating gear 26 follows the movable plate 2 and is slidably connected in the sleeve 1. A movable rod 3 is installed above the movable plate 2. The movable rod 3 controls the horizontal sliding of the movable plate 2. After the movable plate 2 drives the rotating gear 26 to slide to the left, the rotating gear 26 is locked. After the movable plate 2 drives the rotating gear 26 to slide to the right, the rotating gear 26 can rotate.

[0041] The movable plate 2 controls the rotating gear 26 to move horizontally in the sleeve 1 , and controls the rotating gear 26 to rotate or lock according to the position of the rotating gear 26 in the sleeve 1 .

[0042] A fixed wheel 5, wherein the fixed wheel 5 is arranged at the opening of the sleeve 1, wherein a plurality of sliders 52 are slidably connected inside the fixed wheel 5, wherein a plurality of clamps 6 are arranged outside the opening of the fixed wheel 5, wherein the clamps 6 are slidably connected to the fixed wheel 5, and the clamps 6 are clamped with screws or nuts, and wherein the sliders 52 drive the expansion or contraction of the clamps 6.

[0043] By sliding the slider 52 on the fixed wheel 5, the clamp 6 is controlled to shrink or expand. When the clamp 6 shrinks, the screws or nuts are clamped and fixed. After the clamp 6 expands, the screws and nuts in the clamp 6 are convenient to install or remove. Moreover, when the model of the screws or nuts changes, the clamp 6 can effectively clamp and fix them.

[0044] A movable column 21 is fixedly connected to the side of the movable plate 2 away from the opening of the sleeve 1, and a fixed column 23 is fixedly connected to the inner wall of the side of the sleeve 1 connected to the power tool. The movable column 21 is inserted into the fixed column 23, and the movable column 21 is horizontally slidably connected to the fixed column 23. A plurality of splines 22 are fixedly connected to the side wall of the end of the movable column 21 away from the movable plate 2, and a spline groove 24 corresponding to the spline 22 is provided on the inner wall of the fixed column 23, and the spline 22 is inserted into the spline groove 24, and the spline 22 is horizontally slidably connected to the spline groove 24. A first spring 25 is provided between the fixed column 23 and the movable column 21, and one end of the first spring 25 is fixedly connected to the inner wall of the fixed column 23, and the other end of the first spring 25 is fixedly connected to the movable column 21.

[0045] By means of the horizontal sliding of the movable column 21 in the fixed column 23 and the sliding of the spline 22 in the spline groove 24, the rotation between the movable column 21 and the fixed column 23 is restricted, so that the movable column 21 keeps a fixed direction during the sliding process in the fixed column 23, that is, the sliding of the movable plate 2 in the sleeve 1 does not rotate, and under the elastic force of the first spring 25, the movable column 21 is always pulled in the direction of the fixed column 23 to ensure that the movable column 21 and the fixed column 23 remain in a contracted state, that is, the movable plate 2 remains close to the direction of connection between the sleeve 1 and the power tool in the absence of external force.

[0046] The portion of the sleeve 1 located above the movable plate 2 is provided with a movable groove 12, and positioning grooves 11 are respectively provided at both ends of the movable groove 12, and the movable groove 12 and the positioning groove 11 both pass through the upper inner wall of the sleeve 1, and the positioning groove 11 is communicated with the movable groove 12, and the width of the movable groove 12 is smaller than the radius of the positioning groove 11, and the movable rod 3 is fixedly connected to the upper side of the movable plate 2, and the movable rod 3 passes through the positioning groove 11, and the movable rod 3 is slidably connected to the positioning groove 11 and the movable groove 12, and a positioning block 31 is sleeved above the movable rod 3, and the positioning block 31 is vertically slidably connected to the movable rod 3, and the positioning block 31 is clamped with the positioning groove 11, and a second spring 32 is provided in the positioning block 31, and one end of the second spring 32 is fixedly connected to the top inner wall of the positioning block 31, and the other end of the second spring 32 is fixedly connected to the upper end of the movable rod 3.

[0047] The movable rod 3 slides horizontally in the positioning groove 11 and the movable groove 12, so that the movable rod 3 will not hinder the horizontal sliding of the movable plate 2 in the sleeve 1. However, since the positioning block 31 is engaged with the positioning groove 11, the movable plate 2 cannot slide horizontally after the positioning block 31 is in the positioning groove 11, and the position of the movable plate 2 is fixed. Since the positioning block 31 and the movable rod 3 can slide up and down, the sliding of the movable plate 2 can be achieved after the positioning block 31 is pulled upward to slide out of the positioning groove 11, and after the positioning block 31 is released, the elastic force of the second spring 32 makes the positioning block 31 be inserted into the positioning groove 11 again for engagement.

[0048] A fixed gear 4 and a transmission gear 41 are respectively provided on the left and right sides of the rotating gear 26. The fixed gear 4 is fixedly installed in the sleeve 1 through a first connecting rod 42, and the transmission gear 41 is rotatably installed in the sleeve 1 through a second connecting rod 43. The fixed gear 4 is away from the opening direction of the sleeve 1, and the transmission gear 41 is arranged in the opening direction of the sleeve 1. The fixed gear 4 is arranged in the sleeve 1, and the outer side of the transmission gear 41 passes through the outer wall of the sleeve 1. The fixed gear 4 and the transmission gear 41 are both meshed with the rotating gear 26.

[0049] When the positioning block 31 is inserted into the positioning groove 11 away from the opening of the sleeve 1, the movable plate 2 is away from the opening of the sleeve 1, and the rotating gear 26 is meshed with the fixed gear 4. Since the fixed gear 4 is fixed and cannot rotate, the rotating gear 26 is locked and cannot rotate.

[0050] When the positioning block 31 is inserted into the positioning groove 11 near the opening of the sleeve 1, the movable plate 2 is close to the opening of the sleeve 1, and the rotating gear 26 is meshed with the transmission gear 41. Since the side of the transmission gear 41 passes through the outer wall of the sleeve 1, the rotating gear 26 can be driven to rotate by turning the transmission gear 41.

[0051] A plurality of fixing rods 55 are fixedly connected to the side wall of the fixing wheel 5, and the outer sides of the fixing rods 55 are fixedly connected to the inner wall of the sleeve 1. A plurality of sliding grooves 51 are arranged in the non-center part of the fixing wheel 5, and the slider 52 is slidably connected in the sliding groove 51. A third connecting rod 53 is fixedly connected to the slider 52, and the third connecting rod 53 is arranged in an L shape. The other end of the third connecting rod 53 is fixedly connected to the inner wall of the splint 6, and the inward and outward sliding of the slider 52 drives the contraction and expansion of the splint 6 through the third connecting rod 53.

[0052] The slider 52 slides outward in the slide groove 51, so that the third connecting rod 53 drives the clamping plate 6 to expand outward, which facilitates the installation and removal of the screws and nuts. The slider 52 slides inward in the slide groove 51, so that the clamping plate 6 contracts inward to clamp and fix screws and nuts of different models.

[0053] The fixed wheel 5 is provided with a rotating wheel 7 in the direction of the opening of the sleeve 1, a rotating groove 54 is provided in the fixed wheel 5, a plurality of evenly distributed ball blocks 72 are fixedly connected to the outer side of the rotating wheel 7 toward one end of the fixed wheel 5, the ball blocks 72 are arranged in the rotating groove 54, and the ball blocks 72 rotate in the rotating groove 54, the rotating wheel 7 is provided with an inclined groove 71 with the same distribution as the sliding groove 51, the inclined groove 71 runs through the rotating wheel 7, the inclined groove 71 and the sliding groove 51 are cross-arranged, the third connecting rod 53 passes through the inclined groove 71 horizontally, and the relative rotation of the inclined groove 71 and the sliding groove 51 drives the third connecting rod 53 to slide inward or outward.

[0054] By staggered arrangement of the inclined groove 71 and the slide groove 51, when the inclined groove 71 and the slide groove 51 rotate relative to each other, the third connecting rod 53 is controlled to slide inward or outward, thereby driving the contraction or expansion of the splint 6, and by the rotation of the ball block 72 in the rotating groove 54, the rotating wheel 7 is installed on the fixed wheel 5, and the two can rotate relative to each other.

[0055] A plurality of sliding grooves are provided on the side wall of the rotating wheel 7, and a positioning rod 73 is slidably connected in the sliding groove. The positioning rod 73 is set to be trapezoidal, and the outer side of the positioning rod 73 is set to be a bevel. A plurality of tooth grooves 13 are provided on the inner wall of the sleeve 1. The tooth grooves 13 are distributed in the same manner as the positioning rod 73. The end of the positioning rod 73 is inserted into the tooth groove 13, and the positioning rod 73 is unidirectionally engaged with the tooth groove 13.

[0056] Since the positioning rod 73 is set to be a trapezoid and its end is set to be a bevel, the end of the positioning rod 73 can be inserted into the gap between the tooth blocks of the tooth groove 13, and the bevel of the positioning rod 73 can be telescopically moved along the bevel of the tooth block of the tooth groove 13, but the outer right-angled side of the positioning rod 73 will abut the right-angled side of the tooth block of the tooth groove 13, so that the splint 6 can be directly contracted when it contracts inwardly, but when the splint 6 expands outward, the positioning rod 73 needs to be contracted into the sliding groove to prevent the splint 6 from loosening during the process of clamping and fixing the screws and nuts.

[0057] The positioning rod 73 is provided with a slot 74 on the side facing the sliding groove, and the slot 74 is horizontally slidably connected to a limiting plate 77, and the inner side of the limiting plate 77 is fixedly connected to a limiting rod 76, and the limiting rod 76 passes through the inner wall of the slot 74, and the inner end of the limiting rod 76 is fixedly connected to the inner wall of the sliding groove, and the part of the limiting rod 76 located outside the positioning rod 73 is sleeved with a third spring 75, one end of the third spring 75 is fixedly connected to the inner end of the positioning rod 73, and the other end of the third spring 75 is fixedly connected to the inner wall of the sliding groove.

[0058] Under the action of the limit plate 77 and the sliding groove, the sliding distance and direction of the positioning rod 73 in the sliding groove are limited. Under the elastic force of the third spring 75, when there is no external force, the positioning rod 73 slides outward, ensuring that when the positioning rod 73 slides in the direction of its hypotenuse, it can shrink so as to pass through the hypotenuse of the tooth block in the tooth groove 13, and when the positioning rod 73 slides in the direction of the right angle, it abuts against the right angle of the tooth block in the tooth groove 13.

[0059] The axial part of the rotating wheel 7 is provided with a cavity structure, and a connecting plate 79 is provided in the cavity of the rotating wheel 7. A plurality of connecting ropes 78 are fixedly connected to the side wall of the connecting plate 79. The number of the connecting ropes 78 is consistent with the number of the positioning rods 73. The outer side of the connecting rope 78 penetrates into the rotating wheel 7 and into the sliding groove. The outer end of the connecting rope 78 is fixedly connected to the inner end of the positioning rod 73.

[0060] A connecting column 8 is fixedly connected to the side of the rotating wheel 7 facing the fixed wheel 5, and the connecting column 8 penetrates the axial part of the fixed wheel 5. The connecting column 8 is rotatably connected to the fixed wheel 5. A transmission column 27 is fixedly connected to the axial part of the rotating gear 26. A slot 81 is provided in the connecting column 8 facing the transmission column 27. The transmission column 27 is horizontally inserted into the slot 81. The cross-sections of the slot 81 and the transmission column 27 are both square. A slide plate 82 is horizontally slidably connected in the slot 81. A push rod 84 is fixedly connected to the side of the slide plate 82 facing the rotating wheel 7, and the push rod 84 abuts against the connecting plate 79. A fourth spring 83 is sleeved on the part of the push rod 84 located in the slot 81, and the two ends of the fourth spring 83 are respectively fixedly connected to the slide plate 82 and the inner wall of the slot 81.

[0061] After the positioning rod 73 pops outward to the maximum value, the connecting rope 78 is tightened and pulled to the connecting plate 79 to the center of the rotating wheel 7. After the connecting plate 79 is forced to move, the connecting rope 78 contracts inward and pulls the positioning rod 73 inward, so that the rotating wheel 7 can rotate in the direction of the right angle side of the positioning rod 73.

[0062] After the transmission column 27 is inserted into the slot 81 of the connecting column 8, since the cross-sections of both are square, the rotation of the rotating gear 26 drives the rotating wheel 7 to rotate. After the transmission column 27 is inserted, the slide plate 82 is pushed to slide inwardly of the slot 81, so that the top rod 84 is displaced and presses against the connecting plate 79 to move it, thereby controlling the contraction of the positioning plug rod 73, so that the rotating wheel 7 can rotate in any direction. After the movable plate 2 drives the rotating gear 26 to move in the opposite direction, the transmission column 27 slides out of the slot 81, and under the elastic force of the fourth spring 83, the slide plate 82 slides toward the opening direction of the slot 81, so that the top rod 84 contracts, and the connecting plate 79 is reset to its initial position.

[0063] The present invention is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
