For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] The following describes a threaded fastener adjustment tool 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0050] like Figure 1 As shown, the adjusting tool 100 of the threaded fastener according to the embodiment of the present invention comprises: a matching seat 1, a pushing member 2 and an elastic member 3. A matching cavity 111 is provided in the matching seat 1. The matching cavity 111 has a first matching opening 1111 and a second matching opening 1112 opposite to each other. Here, the direction in which the first matching opening 1111 and the second matching opening 1112 are arranged can be referred to as the first direction X, that is, the first matching opening 1111 and the second matching opening 1112 are arranged at intervals along the first direction X.

[0051] The mating cavity 111 is used to place the waiting portion 201 of the threaded fastener 300 to be installed, and the tightening tool 500 is suitable for screwing the threaded fastener 300 into the waiting portion 201 from the first mating opening 1111. The pusher 2 is movable relative to the mating seat 1 (such as along the first direction X), and the pusher 2 is arranged corresponding to the second mating opening 1112, and one end of the pusher 2 is used to abut the threaded fastener 300. The elastic member 3 connects the mating seat 1 and the pusher 2 to drive the pusher 2 to abut against the threaded fastener 300.

[0052] It is worth noting that the adjustment tool 100 of the threaded fastener in the embodiment of the present invention is used to assist in the assembly and positioning of the threaded fastener 300, and does not directly participate in driving the movement of the threaded fastener 300. The adjustment tool 100 and the tightening tool 500 work in cooperation with each other, and the tightening tool 500 is used to directly drive the movement of the threaded fastener 300 to accurately assemble the threaded fastener 300 on the part to be installed 201.

[0053] It is also worth noting that the threaded fastener adjustment tool 100 according to the embodiment of the present invention has a wide range of applications. For example, it can be applied to the height adjustment of the positioning bolt 300a of the four-link hinge 200 of a vehicle.

[0054] The mating seat 1 is used to cooperate with the portion to be installed 201. The portion to be installed 201 extends into the mating cavity 111 placed in the mating seat 1, which can improve the mating stability of the mating seat 1 and the portion to be installed 201, and is conducive to improving the working reliability of the adjustment tool 100. The mating cavity 111 has a first mating opening 1111 extending toward the threaded fastener 300 and passing through the mating seat 1, and a second mating opening 1112 extending toward the pusher 2 and passing through the mating seat 1. The tightening tool 500 screws the threaded fastener 300 into the portion to be installed 201, and the tightening tool 500 drives the threaded fastener 300 to move in the first direction X from the first mating opening 1111 to the second mating opening 1112.

[0055] The pushing member 2 can move relative to the mating seat 1 in the first direction X. The pushing member 2 and the mating seat 1 are connected by an elastic member 3. The elastic member 3 has a movement tendency to drive the pushing member 2 to move toward the mating seat 1. Therefore, the pushing member 2 abuts against the threaded fastener 300 in the first direction X from the second mating opening 1112 to the first mating opening 1111.

[0056] When the tightening tool 500 screws the threaded fastener 300 into the installation portion 201, it not only drives the threaded fastener 300 to move from the first mating opening 1111 to the second mating opening 1112 in the first direction X, but also drives the pushing member 2 to move from the first mating opening 1111 to the second mating opening 1112 in the first direction X by overcoming the elastic force of the elastic member 3.

[0057] Through the above design, the moving height of the threaded fastener 300 in the first direction X can be magnified and intuitively displayed by the pusher 2. The pusher 2 is always in contact with the threaded fastener 300 under the action of the elastic member 3, and the movement amount of the pusher 2 relative to the mating seat 1 in the first direction X is the moving height of the threaded fastener 300 in the first direction X.

[0058] Among them, Figure 2-Figure 5As shown, the mating seat 1 is provided with a first conductive portion 1a, for example, at least part of the inner circumference of the mating cavity 111 is the first conductive portion 1a. The pusher 2 is provided with a second conductive portion 2a, for example, at least part of the outer circumference of the pusher 2 is the second conductive portion 2a, and the first conductive portion 1a and the second conductive portion 2a constitute a switch control circuit of the tightening tool 500.

[0059] The tightening tool 500 is an electrical device. For example, the tightening tool 500 may be an electric gun. The electric gun drives the threaded fastener 300 to be screwed into the to-be-installed portion 201 , so that the threaded fastener 300 can be quickly assembled into place.

[0060] like Figure 2 and Figure 3 As shown, when the pushing member 2 at least partially extends into the mating seat 1, the outer circumferential surface of the pushing member 2 and the inner circumferential surface of the mating cavity 111 contact each other, at this time the first conductive part 1a and the second conductive part 2a contact each other, the first conductive part 1a, the second conductive part 2a and the tightening tool 500 form a loop, and the tightening tool 500 can be started to screw the threaded fastener 300 into the to-be-installed part 201.

[0061] like Figure 4 and Figure 5 As shown, the first conductive part 1a and the second conductive part 2a are disconnected, the first conductive part 1a, the second conductive part 2a and the tightening tool 500 cannot form a loop, the tightening tool 500 is closed, and the threaded fastener 300 does not move relative to the mounting part 201.

[0062] Whether the first conductive part 1a and the second conductive part 2a are in contact can control whether the tightening tool 500 is turned on, so the first conductive part 1a and the second conductive part 2a constitute a switch control circuit of the tightening tool 500. The movement of the pusher 2 can control whether the first conductive part 1a and the second conductive part 2a are in contact, and the movement of the pusher 2 is driven by the threaded fastener 300. Therefore, the adjustment device of the embodiment of the present invention constitutes a self-control device, and the movement height of the threaded fastener 300 reversely controls whether the tightening tool 500 works, so that the threaded fastener 300 can be quickly and accurately assembled to the pre-installed position of the waiting part 201.

[0063] The pushing member 2 has a first position, a second position and a third position. In the first position, the pushing member 2 abuts against the mounting portion 201. From the first position to the second position, the first conductive portion 1a is always in contact with the second conductive portion 2a. From the second position to the third position, the first conductive portion 1a is disconnected from the second conductive portion 2a.

[0064] like Figure 2As shown, the pusher 2 is located at the first position, and driven by the elastic member 3, the pusher 2 abuts against the to-be-installed portion 201, and at the same time, the pusher 2 abuts against the threaded fastener 300. At this time, the first conductive portion 1a and the second conductive portion 2a are in contact, and the tightening tool 500 works.

[0065] like Figure 3 As shown, the pusher 2 is located at an intermediate position between the first position and the second position, at which time the first conductive portion 1a and the second conductive portion 2a are in contact, and the tightening tool 500 is working. The tightening tool 500 drives the threaded fastener 300 to screw into the waiting portion 201, and the tightening tool 500 drives the threaded fastener 300 to move in the first direction X from the first matching opening 1111 to the second matching opening 1112. The pusher 2 also moves in the first direction X from the first matching opening 1111 to the second matching opening 1112 under the drive of the threaded fastener 300.

[0066] like Figure 4 As shown, the threaded fastener 300 pushes the pusher 2 to the second position. At this time, the first conductive part 1a and the second conductive part 2a are just disconnected, the tightening tool 500 stops working, and the threaded fastener 300 remains motionless relative to the mounting part 201. The threaded fastener 300 is assembled to the preset position of the mounting part 201.

[0067] like Figure 5 As shown, the push member 2 is located at the third position, at which time the threaded fastener 300 has been assembled to the preset position of the mounting portion 201, and the push member 2 is driven by external force to move from the second position to the third position. The process of the push member 2 moving from the second position to the third position has no effect on the tightening tool 500.

[0068] like Figure 4 and Figure 5 As shown, the first conductive part 1a and the second conductive part 2a are disconnected, the tightening tool 500 is controlled to stop working, and the threaded fastener 300 is immobile relative to the mounting part 201, and the threaded fastener 300 is driven to stop at the height h protruding from the mounting part 201. Through the adjustment tool 100 of the embodiment of the present invention, the threaded fastener 300 can be quickly and accurately assembled to the height h protruding from the mounting part 201.

[0069] It is worth noting that if Figure 3 and Figure 4 As shown, when using the adjusting tool 100 of the embodiment of the present invention, it is not necessary to start the pusher 2 from the first position. When the threaded fastener 300 has protruded from the first matching opening 1111 to the second matching opening 1112 out of the waiting portion 201, that is, the threaded fastener 300 is already in the Figure 3When the adjusting tool 100 is in the position shown, after the mounting part 201 is assembled with the adjusting tool 100, the pusher 2 stops on the threaded fastener, and the pusher 2 starts to work from the middle position between the first position and the second position. The adjusting tool 100 can adjust the height of the threaded fastener 300, and the threaded fastener 300 can be quickly and accurately moved from Figure 3 The position shown drives Figure 4 Position shown.

[0070] It is also worth noting that the height of the threaded fastener 300 assembled to the portion to be installed 201 is determined by the size of the first conductive part 1a in the first direction X. Whether the first conductive part 1a and the second conductive part 2a are in contact controls whether the tightening tool 500 is turned on, and the first conductive part 1a moves relative to the first conductive part 1a in the first direction X, and the second conductive part 2a does not move relative to the portion to be installed 201. Therefore, by adjusting the size of the first conductive part 1a in the first direction X, the height of the threaded fastener 300 assembled to the portion to be installed 201 can be adjusted. The adjustment work of the embodiment of the present invention can select first conductive parts 1a of different sizes according to actual needs, thereby improving the application range of the adjustment tool 100.

[0071] According to the adjustment tool 100 of the threaded fastener according to the embodiment of the present invention, whether the tightening tool 500 is turned on is controlled by setting whether the second conductive part 2a of the pusher 2 and the first conductive part 1a of the mating seat 1 are conductive, and whether the tightening tool 500 is working is reversely controlled by the moving height of the threaded fastener 300, so that the threaded fastener 300 can be quickly and accurately assembled to the pre-installed position of the to-be-installed part 201.

[0072] In some embodiments of the present invention, Figure 2 As shown, the first conductive part 1a and the tightening tool 500 are connected via a first wire 401, and the second conductive part 2a and the tightening tool 500 are connected via a second wire 402. When the first conductive part 1a and the second conductive part 2a are in contact, the tightening tool 500 can work.

[0073] In some embodiments of the present invention, Figure 1 As shown, the mating seat 1 includes: a base 11 and a positioning piece 12, as shown in FIG. Figure 6 As shown, the matching cavity 111, the first matching opening 1111, and the second matching opening 1112 are formed on the base 11, and the positioning piece 12 is connected to the base 11. The positioning piece 12 is arranged on the side of the base 11 where the second matching opening 1112 is arranged. Figure 7 As shown, the positioning piece 12 is provided with a positioning opening 121 corresponding to the second matching opening 1112. A part of the first conductive portion 1a is provided on the inner circumference of the positioning opening 121, and a part of the first conductive portion 1a is provided on the inner circumference of the second matching opening 1112.

[0074] The base 11 is used to cooperate with the portion to be installed 201 . The portion to be installed 201 extends into a matching cavity 111 placed on the base 11 , which can improve the matching stability between the matching seat 1 and the portion to be installed 201 .

[0075] The positioning piece 12 is arranged on one side of the base 11 where the second matching opening 1112 is provided. The positioning piece 12 is provided with a positioning opening 121 corresponding to the second matching opening 1112. The pushing member 2 moves from the second matching opening 1112 to the first matching opening 1111 in the first direction X, first passes through the positioning opening 121 and then extends into the second matching opening 1112.

[0076] A portion of the first conductive portion 1a is disposed on the inner circumference of the positioning opening 121, and a portion of the first conductive portion 1a is disposed on the inner circumference of the second matching opening 1112. When the pusher 2 slides in the base 11, the first conductive portion 1a and the second conductive portion 2a can contact each other, and when the pusher 2 slides in the positioning piece 12, the first conductive portion 1a and the second conductive portion 2a can also contact each other.

[0077] In some embodiments of the present invention, the positioning sheet 12 is detachably connected to the base 11 .

[0078] The height of the threaded fastener 300 assembled to the mounting portion 201 is determined by the size of the first conductive portion 1a in the first direction X. Whether the first conductive portion 1a and the second conductive portion 2a are in contact controls whether the tightening tool 500 is turned on, and the first conductive portion 1a moves relative to the first conductive portion 1a in the first direction X, and the second conductive portion 2a does not move relative to the mounting portion 201. Therefore, by adjusting the size of the first conductive portion 1a in the first direction X, the height of the threaded fastener 300 assembled to the mounting portion 201 can be adjusted.

[0079] When the positioning piece 12 is not assembled to the base 11, when the pushing member 2 moves to the point where the second conductive part 2a and the first conductive part 1a of the base 11 are just disconnected, the tightening tool 500 stops working, the threaded fastener 300 remains stationary relative to the mounting part 201, and the height of the threaded fastener 300 protruding from the mounting part 201 is only controlled by the first conductive part 1a on the base 11.

[0080] When the positioning piece 12 is assembled to the base 11, the pushing member 2 moves to the point where the second conductive portion 2a and the first conductive portion 1a of the positioning piece 12 are just disconnected, the tightening tool 500 stops working, the threaded fastener 300 remains stationary relative to the mounting portion 201, and the height of the protruding portion 201 of the threaded fastener 300 is jointly controlled by the first conductive portion 1a on the base 11 and the first conductive portion 1a on the positioning piece 12.

[0081] like Figure 1As shown, the positioning piece 12 is arranged on the side of the base 11 where the second matching opening 1112 is provided. Therefore, when the positioning piece 12 is assembled to the base 11, the threaded fastener 300 can be controlled to protrude from the to-be-installed portion 201 in the first direction X closer to the second matching opening 1112.

[0082] In some embodiments of the present invention, there are at least two positioning sheets 12 , and the thicknesses of the at least two positioning sheets 12 are equal or different.

[0083] By providing a plurality of positioning pieces 12 , positioning pieces 12 of different numbers or sizes can be selected and assembled on the base 11 according to actual needs, so that the threaded fastener 300 can be controlled to be assembled to different preset positions, thereby improving the application range of the adjustment tool 100 .

[0084] Specifically, when the threaded fastener 300 needs to be assembled to a position higher than the mounting portion 201, the number of positioning plates 12 assembled on the base 11 is increased, or positioning plates 12 with larger sizes are assembled; when the threaded fastener 300 needs to be assembled to a position lower than the mounting portion 201, the number of positioning plates 12 assembled on the base 11 is reduced, or positioning plates 12 with smaller sizes are assembled.

[0085] In some specific embodiments of the present invention, the inner circumference of the second matching opening 1112 is configured as a part of the first conductive portion 1a, and the inner circumference of the positioning opening 121 is configured as another part of the first conductive portion 1a. Figure 6 As shown, the dimension of the inner circumference of the second matching opening 1112 in the first direction X is h1, and the dimension of the inner circumference of the positioning opening 121 in the first direction X is h2. Figure 5 As shown, the sum of h1 and h2 is the dimension h of the first conductive portion 1 a in the first direction X.

[0086] The mounting portion 201 is placed in the matching cavity 111, and the end surface of the mounting portion 201 abuts against the inner wall surface of the matching cavity 111. The dimension h of the first conductive portion 1a is the distance between the end of the first conductive portion 1a and the mounting portion 201 in the first direction X.

[0087] The first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 works. The tightening tool 500 drives the threaded fastener 300 to screw into the portion to be installed 201, and the tightening tool 500 drives the threaded fastener 300 to move from the first matching opening 1111 to the second matching opening 1112 in the first direction X. At this time, the adjusting tool 100 can quickly and accurately assemble the threaded fastener 300 to a position protruding from the portion to be installed 201 by a height h.

[0088] When the positioning sheet 12 is removed from the base 11 , the adjusting tool 100 can assemble the threaded fastener 300 to a position protruding from the to-be-assembled portion 201 by a height h1 .

[0089] When there are three positioning pieces 12, including a first positioning piece, a second positioning piece and a third positioning piece, the size of the inner circumference of the first positioning piece in the first direction X is h2a, the size of the inner circumference of the second positioning piece in the first direction X is h2b, the size of the inner circumference of the third positioning piece 2 in the first direction X is h2c, and h2a+h2b+h2c=h2 is satisfied.

[0090] When the first positioning sheet 12 is removed from the base 11 , the adjusting tool 100 can assemble the threaded fastener 300 to a position protruding from the to-be-assembled portion 201 by a height of h1 + h2b + h2c.

[0091] In some embodiments of the present invention, the base 11 and the positioning piece 12 are both conductive members, and the inner circumference of the positioning opening 121 and the inner circumference of the second matching opening 1112 are also conductive members.

[0092] By setting both the base 11 and the positioning piece 12 as conductive parts, the manufacturing cost can be reduced compared to setting only at least part of the inner circumference of the mating cavity 111 as a conductive part, and the integrity of the base 11 and the positioning piece can be improved, which can improve the structural reliability.

[0093] In some embodiments of the present invention, Figure 1 As shown, the adjustment tool 100 also includes: a guide seat 4, which is installed on the matching seat 1 and is an insulating member. Figure 8 As shown, the guide seat 4 is provided with a guide hole 41. One end of the guide hole 41 is open and faces Figure 1 The second matching opening 1112 is provided, and the guide hole 41 is extended along the first direction X. Fig. 9 As shown, a part of the pusher 2 is a guide post 21, which is matched with Figure 8 In the guide hole 41 shown, the assembly effect is as follows Figure 1 shown.

[0094] The guide seat 4 is mounted on the matching seat 1, the guide seat 4 is immovable relative to the matching seat 1, and at least part of the pusher 2 is slidably fitted in the guide hole 41 of the guide seat 4. The guide seat 4 guides the pusher 2, guides the pusher 2 to move stably along the first direction X, reduces the shaking of the pusher 2, and improves the movement stability of the pusher 2, thereby improving the working reliability of the adjustment work.

[0095] The guide seat 4 is an insulating member, which can prevent the pusher 2 and the guide seat 4 from contacting and causing short circuit discharge, thereby improving the safety of the adjustment work.

[0096] In some embodiments of the present invention, Fig. 9 As shown, the pusher 2 further includes: an abutment post 22 connected to one end of the guide post 21 facing the mating cavity 111, and the outer peripheral surface of the abutment post 22 is formed Figure 2 The second conductive portion 2a is shown.

[0097] like Figure 8 As shown, the guide seat 4 further includes an accommodating cavity 42 disposed at one end of the guide hole 41 facing the matching cavity 111 , and the abutting column 22 is located in the accommodating cavity 42 when the pushing member 2 is located at the third position.

[0098] The guide seat 4 can also play a limiting role, such as Fig. 9 As shown, the cross-sectional dimension of the abutment column 22 is larger than the cross-sectional dimension of the guide column 21, and the abutment column 22 cannot enter the Figure 8 The guide hole 41 shown in FIG. Figure 1 As shown, the guide seat 4 limits the movement of the pushing member 2 from the first mating opening 1111 to the second mating opening 1112 in the first direction X. When the pushing member 2 is in the third position and the pushing member 2 is completely separated from the mating seat 1, the pushing member 2 will also be limited by the guide seat 4 to prevent the pushing member 2 from escaping from the adjustment tooling 100, thereby improving the working reliability of the adjustment work.

[0099] In some embodiments of the present invention, Figure 1 As shown, the adjustment tool 100 also includes a guide column 6 and a fixed plate 5. The guide column 6 is installed on the matching seat 1. The fixed plate 5 is spaced apart from the matching seat 1 along the first direction X. The fixed plate 5 is slidably connected to the guide column 6. One end of the pusher 2 is installed on the fixed plate 5.

[0100] The guide column 6 is connected to the matching seat 1, and the guide column 6 and the matching seat 1 are relatively fixed. The fixed plate 5 is connected to the pushing member 2, and the fixed plate 5 and the pushing member 2 are relatively fixed, and the fixed plate 5 can move in the first direction X relative to the guide column 6 and the matching seat 1.

[0101] The guide column 6 guides the fixed plate 5 , and extends along the first direction X. The guide column 6 guides the fixed plate 5 to stably move along the first direction X. The fixed plate 5 is connected to the pusher 2 , so the guide column 6 can also guide the pusher 2 to stably move along the first direction X, thereby improving the reliability of the adjustment work.

[0102] In some embodiments of the present invention, there are two guide pillars 6 , and the two guide pillars 6 sandwich the pusher 2 , which can further enhance the movement stability of the pusher 2 .

[0103] In some embodiments of the present invention, the elastic member 3 is a spring 3a and is sleeved on the guide column 6, one end of the elastic member 3 is connected to the fixing plate 5 and the other end is connected to the matching seat 1. Fig.11 As shown, the spring 3 a is a cylindrical spring and is sleeved on the guide column 6 .

[0104] The guide column 6 not only guides the movement of the push member 2, but also supports the installation of the elastic member 3. The elastic member 3 is sleeved on the guide column 6, and the elastic member 3 is also limited to be deformed only in the first direction X, which can reduce the deformation and offset of the elastic member 3 and improve the working stability of the adjustment work.

[0105] One end of the elastic member 3 is connected to the fixed plate 5, and the other end of the elastic member 3 is connected to the matching seat 1. The elastic member 3 drives the fixed plate 5 to move toward the pushing member 2. The fixed plate 5 and the pushing member 2 are connected, so that the pushing member 2 is pulled to abut against the threaded fastener 300.

[0106] In some embodiments of the present invention, Fig.10 As shown, the fixing plate 5 is provided with a fixing opening 51, which is arranged through the fixing opening 51 along the first direction X, and the fixing opening 51 forms a socket 511 on one side of the fixing plate 5. Fig. 9 As shown, the pusher 2 is provided with a thin neck section 23, and the thin neck section 23 is Fig.10 The socket 511 shown can be detachably assembled in the fixing opening 51 .

[0107] The cross-sectional dimension of the thin neck section 23 is smaller than that of the guide pillar 21 , and the thin neck section 23 and the fixing opening 51 cooperate with each other to connect the pusher 2 and the fixing plate 5 , so that the fixing plate 5 and the pusher 2 move together.

[0108] The fixing opening 51 extends toward one side of the fixing plate 5 to form a socket 511 that passes through the edge of the fixing plate 5. The thin neck section 23 can be assembled into the fixing hole via the socket 511, and can also be removed from the fixing hole via the socket 511. The socket 511 is provided to facilitate assembly and disassembly of the pushing member 2 and the fixing plate 5.

[0109] In other embodiments of the present invention, the pushing member 2 is fixedly connected to the fixing plate 5, and the pushing member 2 does not need to be assembled or disassembled from the fixing plate 5, which can improve the connection reliability between the pushing member 2 and the fixing plate 5.

[0110] Furthermore, the pushing member 2 and the fixing plate 5 are an integrally formed part, which can further improve the connection stability of the pushing member 2 and the fixing plate 5 , and can also improve the structural reliability of the pushing member 2 and the fixing plate 5 .

[0111] In some embodiments of the present invention, Figure 1 As shown, the mating seat 1 is provided with an opening 112, which is located on a side surface of the mating seat 1 perpendicular to the surface where the first mating opening 1111 is located. That is, the opening 112 is located on one side of the mating seat 1 in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0112] The mounting portion 201 is inserted into the matching cavity 111 through the opening 112 , and the opening 112 extends along a second direction Y perpendicular to the first direction X, so that the threaded fastener can move along a direction perpendicular to the mounting portion 201 .

[0113] In some embodiments of the present invention, Figure 1 and Figure 6 As shown, the opening 112 is formed on the base 11 .

[0114] The positioning piece 12 only needs to provide a dimension in the first direction X, so the cross-sectional area of ​​the positioning piece 12 is much smaller than the base 11 , which can save the manufacturing cost of the adjustment work and improve the efficiency of disassembly and assembly of the positioning piece 12 .

[0115] In some embodiments of the present invention, an end of the pushing member 2 for abutting against the threaded fastener 300 is provided with an insulating layer.

[0116] The threaded fastener 300 may be a conductor, and an insulating layer is provided at one end where the pusher 2 and the threaded fastener 300 abut against each other, so that discharge from the pusher 2 to the threaded fastener 300 can be avoided, thereby improving the safety of the adjustment work.

[0117] In some embodiments of the present invention, an insulating film is attached to one end of the push piece for abutting against the threaded fastener 300 .

[0118] In some embodiments of the present invention, Fig. 9 As shown, the pushing member 2 is a rotating body.

[0119] The pushing member 2 is a rotating body, and the center of gravity of the pushing member 2 is located on the axis, which can improve the movement stability of the pushing member 2 in the first direction X, reduce the shaking of the pushing member 2, and thus improve the working reliability of the adjustment work.

[0120] In some embodiments of the present invention, the pushing member 2 is a conductive member. Compared with only setting at least a portion of the outer circumference of the pushing member 2 as a conductive member, the pushing member 2 as a whole is a conductive member, which can reduce manufacturing costs, improve the integrity of the pushing member 2, and improve structural reliability.

[0121] When the pusher 2 is a conductive member as a whole, the pusher 2 as a whole can constitute the second conductive portion 2a. Of course, in other embodiments, the pusher 2 can also be set as an insulator, and then a wire is set on the pusher 2 as the second conductive portion 2a.

[0122] In some embodiments of the present invention, Fig.12 and Fig.13As shown, the adjustment work is used to adjust the height of the positioning bolt 300a of the four-link hinge 200 of the vehicle. The height of the positioning bolt 300a has a great influence on the Z-axis cooperation between the front cover and the fender. In order to ensure the Z-axis cooperation between the front cover and the fender, it is required to adjust the positioning bolt 300a to the required height through the adjustment work.

[0123] In the related art, the method for adjusting the positioning bolts is to adjust the height of the positioning bolts and then measure the height of the positioning bolts. If it is unqualified, continue to adjust the height, and then test it after adjustment. Repeat the above steps until the height of the positioning bolts meets the target requirements.

[0124] The adjusting tool 100 according to the embodiment of the present invention can be used to quickly adjust the positioning bolt 300 a of the four-bar hinge 200 , and can quickly and accurately adjust the positioning bolt 300 a to a required height.

[0125] The working process of the adjusting tool 100 according to the embodiment of the present invention will be described below with reference to the accompanying drawings, wherein the tightening tool 500 is an electric gun.

[0126] First, lower the height of the positioning bolt 300a to be visibly lower than the required height, and assemble the adjustment tooling 100 onto the part to be installed 201, that is, assemble the adjustment tooling onto the four-bar hinge 200, and the upper surface of the mating cavity 111 close to the second mating port 1112 is in contact with the part to be installed 201.

[0127] Under the elastic force of the elastic member 3, the lower surface of the pushing member 2 facing the matching seat 1 contacts the positioning bolt 300a. At this time, the pushing member 2 contacts the matching seat 1, and the pushing member 2, the matching seat 1 and the electric gun form a closed circuit. The electric gun protrudes from the bottom of the mounting portion 201 from the positioning bolt 300a to operate and tighten the positioning bolt 300a.

[0128] During the tightening process, the height of the positioning bolt 300a increases, and the positioning bolt 300a pushes the pusher 2 to move upward. When the pusher 2 is pushed to no longer contact the mating seat 1, the electric gun is disconnected and stops running. At this time, the height of the positioning bolt 300a is h, h=h1+h2.
