DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] See also Figure 1-Figure 3 The utility model provides a technical solution: an adjustable torque wrench, comprising a wrench body 1, a first handle 2 fixedly mounted on the bottom of the wrench body 1, a length adjustment mechanism 3 for extending the length of the first handle 2 being provided inside the first handle 2, and a direction adjustment mechanism 4 for changing the gripping position being fixedly mounted on one side of the length adjustment mechanism 3.
[0019] Among them, the wrench body 1 and the first handle 2 provided can realize the screwing construction operation, and the length adjustment mechanism 3 provided inside the first handle 2 can increase the length distance of the gripping part to a certain extent, thereby facilitating the gripping operation of the wrench body 1, and the direction adjustment mechanism 4 provided can perform the screwing operation through the extended direction adjustment mechanism 4 when encountering a position with a small gap or an obstacle on one side of the wrench body 1, thereby increasing the operability of the device to a certain extent.
[0020] See also Figure 1 The wrench body 1 includes a connecting tube 5, a wrench head 6, a positioning block 7 and an adjustment seat 8. A first handle 2 is provided at the bottom of the connecting tube 5, and an adjustment seat 8 is provided on the outer surface of the connecting tube 5. The wrench head 6 is fixedly installed on the top of the wrench body 1, and a positioning block 7 is rotatably connected to the wrench head 6.
[0021] The wrench head 6 and the positioning block 7 installed on the connecting pipe 5 can perform a screwing operation on the components that need to be screwed.
[0022] See also Figure 1 、 Figure 2 and Figure 3 The length adjustment mechanism 3 includes a positioning piece 9, a threaded sleeve 12, an adjusting rod 13, and a fixing piece 14. Multiple groups of positioning pieces 9 are arranged inside the first handle 2. An avoidance groove 10 is formed between the positioning pieces 9 located on the same horizontal plane, and a clamping groove 11 is formed between the positioning pieces 9 located on the same vertical plane. An adjusting rod 13 is threadedly connected to one side of the threaded sleeve 12. Three groups of fixing pieces 14 are fixedly connected to the outer surface of the adjusting rod 13 and the position corresponding to the avoidance groove 10. The fixing piece 14 is clamped to the inside of the clamping groove 11.
[0023] Among them, when the operating space is small and the bottom grip position needs to be extended, the fixing plate 14 on the outer surface of the adjusting rod 13 is aligned with the inside of the avoidance groove 10 and then, when the insertion distance is appropriate, the threaded sleeve 12 and the adjusting rod 13 are rotated to make the fixing plate 14 snap into the corresponding snap-fit groove 11, so that the fixing plate 14 fits with the vertically adjacent positioning plate 9, and multiple groups of snap-fit grooves 10 can make the position adjustment more precise.
[0024] See also Figure 1 、 Figure 2 and Figure 3 The direction adjustment mechanism 4 includes an adjustment frame 15, a pin 17 and a second handle 18. The adjustment frame 15 is fixedly connected to one side of the threaded sleeve 12. A bearing groove 16 is provided on the top of the adjustment frame 15. The inside of the bearing groove 16 is rotatably connected to the second handle 18 through the pin 17.
[0025] Among them, when encountering an obstacle on one side of the wrench body at a position with a smaller gap during use of the device, the second handle 18 is pulled open, and the second handle 18 is rotated along the pin shaft 17 and disengaged from the inside of the bearing groove 16, so that the operator can conveniently hold the extended second handle 18 to operate the wrench body 1 to work.
[0026] See also Figure 1 、 Figure 2 and Figure 3 An extension groove 20 extending into the interior of the bearing groove 16 is provided at the bottom of the adjustment frame 15 , and damping pads 19 made of rubber material are fixedly installed on both sides of the inner wall of the bearing groove 16 , and the damping pads 19 are in contact with the outer wall of the second handle 18 .
[0027] The damping pad 19 prevents the second handle 18 from falling out of the bearing slot 16 when not in use, and the extending slot 20 facilitates pushing the second handle 18 out of the bearing slot 16 .
[0028] See also Figure 2 The opposite sides of the three groups of positioning pieces 9 located on the same horizontal plane are arc-shaped, and the outer wall of the adjusting rod 13 fits with the positioning piece 9.
[0029] The outer wall of the adjusting rod 13 fits in with the inner wall of the positioning piece 9 , which can prevent the adjusting rod 13 from shaking between the positioning pieces 9 during operation.
[0030] When in use, first, the wrench body 1 and the first grip 2 provided can realize the screwing construction operation, and the length adjustment mechanism 3 provided inside the first grip 2 can increase the length distance of the gripping part to a certain extent, thereby facilitating the gripping operation of the wrench body 1, and the direction adjustment mechanism 4 provided can be used to perform the screwing operation when encountering a position with a small gap or when there is an obstacle on one side of the wrench body 1, which increases the operability of the device to a certain extent. The wrench head 6 and the positioning block 7 installed on the connecting pipe 5 can be used to screw the parts that need to be screwed. When the operating space is small and the bottom gripping position needs to be extended, the fixing piece 14 on the outer surface of the adjusting rod 13 is aligned with the inside of the avoidance groove 10 and then inserted when the insertion distance is appropriate. By rotating the threaded sleeve 12 and the adjusting rod 13, the fixing plate 14 can be snapped into the corresponding snap-in groove 11, so that the fixing plate 14 fits into the vertically adjacent positioning plate 9, and the multiple groups of snap-in grooves 10 can make the position adjustment more precise. When the device encounters an obstacle on one side of the wrench body at a position with a small gap during use, the second handle 18 is pulled open and the second handle 18 is rotated along the pin shaft 17 to disengage from the inside of the bearing groove 16. This allows the operator to conveniently hold the extended second handle 18 to operate the wrench body 1 to work. The damping pad 19 provided can prevent the second handle 18 from disengaging from the inside of the bearing groove 16 when the second handle 18 is not in use, and the extended groove 20 provided facilitates pushing the second handle 18 out of the inside of the bearing groove 16.
