[Specific implementation method]

[0025] The technical features of the present invention are further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand them.

[0026] A return wrench structure for adjusting the height of the equipment base, such as Figure 1 to Figure 7As shown, it includes a bottom shell 1 and a cover plate 2 installed and fixed on the bottom shell 1, a gear shaft 3 is rotatably provided in the bottom shell 1, a connecting rod 4 and a screw 5 are respectively provided at the upper and lower ends of the gear shaft 3 to rotate synchronously with the gear shaft 3 and are used to connect the bottom end of the device and the base respectively, a block 6 for abutting the gear shaft 3 at one end is rotatably provided in the bottom shell 1 and located on one side of the gear shaft 3, and teeth 7 protruding toward the gear shaft 3 are provided at both ends of the block 6, a push rod 8 for driving the block 6 to rotate is swingably provided in the bottom shell 1 and located on the side of the block 6 away from the gear shaft 3, a retractable and movable top head 9 is provided in the top rod 8, the top head 9 is against the block 6, and a button 10 for manually changing the end position of the top rod 8 against the block 6 to change the reverse direction is provided at the end of the top rod 8; the reverse wrench structure can drive the screw 5 When rotating to a dead angle, while the gear shaft 3 and the screw rod 5 are stationary, other structures are manually rotated in the reverse direction to facilitate the next round of driving the screw rod 5 to continue rotating in the same direction. At the same time, the button 10 can be pressed to swing the push rod 8, so that the block 6 rotates around the rotating shaft 12, so that the card teeth 7 at one end of the block 6 are away from the gear shaft 3, and the card teeth 7 at the other end are engaged with the gear shaft 3 to change the reverse direction, thereby facilitating the height adjustment of the equipment base or casters, making it stable and horizontally placed. Moreover, the reverse wrench structure is easy to assemble, and the button 10 is arranged at the outermost end of the reverse wrench structure, which can prevent fingers from reaching into the gap between the equipment and the base, making it easy and safer to use. At the same time, there is no gap on the outside of the reverse wrench structure, which can prevent dust and debris generated during the production and processing of the equipment from entering the shell, and prevent the reverse wrench structure from being blocked internally due to long-term placement, affecting its use.

[0027] Specifically, the working principle of the return wrench structure is as follows:

[0028] The reverse wrench structure is screwed to the equipment base through the screw rod 5, so when the screw rod 5 is driven to rotate by the reverse wrench structure, the height of the equipment can be adjusted. Since the push rod 8 and the push head 9 abut against one end of the block 6, the latching tooth 7 at one end of the block 6 meshes with the gear shaft 3. If the reverse wrench structure drives the screw rod 5 to rotate in the clockwise direction, when the reverse wrench structure is turned clockwise by hand, the end of the block 6 meshing with the gear shaft 3, the distance required for the latching tooth 7 to disengage from the gear shaft 3 is greater than the distance the push head 9 retracts, the push rod 8 and the block 6 are in abutment, and the latching tooth 7 at one end of the block 6 is in meshing with the gear shaft 3. Therefore, when the reverse wrench structure is turned clockwise, the screw rod 5 can be driven to rotate clockwise; when the wrench structure needs to be reversed, the wrench is turned counterclockwise by hand. When the locking lever 10 is in the state of being disengaged from the gear shaft 3, the locking tooth 7 at one end of the locking lever 6 that is meshed with the gear shaft 3 is in a disengaged state, and the spacing required for the locking tooth 7 at one end of the locking lever 6 that is meshed with the gear shaft 3 to be disengaged from the gear shaft 3 is smaller than the distance for the top head 9 to retract. Therefore, when the reverse wrench structure rotates counterclockwise, the gear shaft 3, the connecting rod 4 and the screw rod 5 do not rotate, and other structures can rotate counterclockwise in the reverse direction. When the reverse direction needs to be changed, the button 10 is pressed to make the top rod 8 swing, and the top rod 8 drives the top head 9 to move from one end of the locking lever 6 to the other end of the locking lever 6. At this time, the locking lever 6 rotates around the rotating shaft 12, so that the locking tooth 7 at one end of the locking lever 6 is away from the gear shaft 3, and the locking tooth 7 at the other end is meshed with the gear shaft 3. At this time, the reverse direction of the reverse wrench structure is opposite to that before, and the reverse process is the same as above.

[0029] Specifically, a through hole 11 is provided on the block 6, and a rotating shaft 12 passing through the through hole 11 is provided on the cover plate 2. The block 6 rotates around the rotating shaft 12 under the manipulation of the push rod 8, so that the tooth 7 at one end of the block 6 is away from the gear shaft 3, and the tooth 7 at the other end is engaged with the gear shaft 3 to change the reverse direction.

[0030] In addition, a mounting hole 13 is provided at one end of the push rod 8 close to the gear shaft 3 , and a spring 14 for supporting the push head 9 is provided in the mounting hole 13 . The spring 14 is used to allow the push head 9 to retract and reset in the push rod 8 .

[0031] Specifically, a clamping plate 15 for clamping the edge of the bottom shell 1 is provided at the upper end of the gear shaft 3, and a clamping groove 16 for installing a retaining spring to prevent the gear shaft 3 from escaping from the bottom shell 1 is provided at the lower end of the gear shaft 3. The clamping plate 15 combined with the retaining spring in the retaining groove 16 can prevent the gear shaft 3 from moving up and down, thereby making the installation of the gear shaft 3 more stable.

[0032] Specifically, a rotation limit column 17 for limiting the swing point of the push rod 8 is provided at the upper and lower ends of the button 10, and a rotation limit groove 18 for inserting the rotation limit column 17 is correspondingly provided on the bottom shell 1 and the cover plate 2. The button 10 and the push rod 8 rotate around the rotation limit column 17, and at the same time, the rotation limit column 17 and the rotation limit groove 18 can clamp the button 10 to prevent the button 10 and the push rod 8 from detaching from the bottom shell 1.

[0033] In addition, the rotation limit column 17 and the rotation limit groove 18 are both fan-shaped and the arc length of the rotation limit column 17 is smaller than the arc length of the rotation limit groove 18, so as to limit the rotation angle of the button 10 and the swing range of the push rod 8, so that the push rod 8 can drive the push head 9 to move from one end of the block 6 to the other end.

[0034] Specifically, a plurality of positioning holes 19 are provided at the edge of the bottom shell 1, and a plurality of positioning pins 20 for inserting into the positioning holes 19 are correspondingly provided on the bottom surface of the cover plate 2, so as to facilitate the assembly and fixation between the bottom shell 1 and the cover plate 2, and up and down lifting indicator marks corresponding to the threads of the screw 5 can be provided on the outer surface of the cover plate 2 or the bottom shell 1, so as to facilitate the user to confirm the direction of use.

[0035] In addition, the button 10 and the push rod 8 are an integrated part, and the gear shaft 3, the connecting rod 4 and the screw rod 5 are an integrated part, which is convenient for assembly.

[0036] The embodiments described in the present invention are merely descriptions of preferred implementation modes of the present invention and are not limited to the precise structures described above and shown in the accompanying drawings. Various modifications and changes may be made without departing from the scope thereof. Various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field without departing from the design concept of the present invention shall all fall within the protection scope of the present invention.
