In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0048] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the 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, a threaded fastener adjustment tool 100 according to an embodiment of the present invention includes: a mating seat 1, a pusher 2, and an elastic member 3. A mating cavity 111 is defined within the mating seat 1. The mating cavity 111 has a first mating opening 1111 and a second mating opening 1112 that are opposed to each other. The direction in which the first mating opening 1111 and the second mating opening 1112 are arranged may be referred to as a first direction X. That is, the first mating opening 1111 and the second mating opening 1112 are arranged at intervals along the first direction X.

[0051] The mating cavity 111 is used to accommodate the mounting portion 201 to which the threaded fastener 300 is to be mounted. The tightening tool 500 is adapted to screw the threaded fastener 300 into the mounting portion 201 through the first mating opening 1111. The pusher 2 is movable (e.g., along the first direction X) relative to the mating seat 1. The pusher 2 is positioned corresponding to the second mating opening 1112, and one end of the pusher 2 is configured to abut the threaded fastener 300. The elastic member 3 connects the mating seat 1 and the pusher 2 to drive the pusher 2 into abutment with the threaded fastener 300.

[0052] It is worth mentioning that the adjusting tool 100 of the threaded fastener in the embodiment of the present application is used for assisting assembly and positioning the threaded fastener 300 and does not directly participate in driving movement of the threaded fastener 300, and the adjusting tool 100 and the tightening tool 500 work cooperatively, and the tightening tool 500 is used for directly driving movement of the threaded fastener 300 to accurately assemble the threaded fastener 300 on the to-be-assembled part 201.

[0053] It is also worth mentioning that the adjusting tool 100 of the threaded fastener in the embodiment of the present application has a wide application range, and for example, can be applied to height adjustment of the positioning bolt 300a of the four-bar linkage 200 of a vehicle.

[0054] The matching seat 1 is used for cooperating with the to-be-assembled part 201, the to-be-assembled part 201 extends into the matching cavity 111 placed in the matching seat 1, the matching stability of the matching seat 1 and the to-be-assembled part 201 can be improved, and the working reliability of the adjusting tool 100 can be improved. The matching cavity 111 has a first matching opening 1111 extending towards the threaded fastener 300 and penetrating through the matching seat 1, and a second matching opening 1112 extending towards the pushing piece 2 and penetrating through the matching seat 1, the tightening tool 500 rotates the threaded fastener 300 into the to-be-assembled part 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.

[0055] The pushing piece 2 is movable relative to the matching seat 1 in the first direction X, the pushing piece 2 and the matching seat 1 are connected through the elastic piece 3, the elastic piece 3 has a movement trend of driving the pushing piece 2 to move towards the matching seat 1, and therefore the pushing piece 2 abuts against the threaded fastener 300 in the first direction X from the second matching opening 1112 to the first matching opening 1111.

[0056] In the process of rotating the threaded fastener 300 into the to-be-assembled part 201 by the tightening tool 500, the tightening tool 500 not only drives the threaded fastener 300 to move in the first direction X from the first matching opening 1111 to the second matching opening 1112, but also drives the pushing piece 2 to move in the first direction X from the first matching opening 1111 to the second matching opening 1112 against the elastic force of the elastic piece 3.

[0057] Through the above design, the movement height of the threaded fastener 300 in the first direction X can be enlarged and intuitively displayed by the pushing piece 2. The pushing piece 2 always abuts against the threaded fastener 300 under the action of the elastic piece 3, and the movement amount of the pushing piece 2 relative to the matching seat 1 in the first direction X is the movement height of the threaded fastener 300 in the first direction X.

[0058] Among them, for example, Figures 2-5As shown, the mating seat 1 is provided with a first conductive portion 1a, for example, at least a portion of the inner circumference of the mating cavity 111 is the first conductive portion 1a. The pushing member 2 is provided with a second conductive portion 2a, for example, at least a portion of the outer circumference of the pushing member 2 is the second conductive portion 2a. The first conductive portion 1a and the second conductive portion 2a constitute the 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 screw into the to-be-installed portion 201 , and the threaded fastener 300 may be quickly assembled into place.

[0060] like Figure 2 and Figure 3 As shown, when the pushing member 2 is at least partially extended 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, and the first conductive part 1a, the second conductive part 2a and the tightening tool 500 form a loop. The tightening tool 500 can start 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 portion 1 a and the second conductive portion 2 a are disconnected, and the first conductive portion 1 a , the second conductive portion 2 a and the tightening tool 500 cannot form a loop. The tightening tool 500 is closed, and the threaded fastener 300 remains stationary relative to the mounting portion 201 .

[0062] Whether the first conductive portion 1a and the second conductive portion 2a are in contact controls whether the tightening tool 500 is turned on, thus forming the on / off control circuit for the tightening tool 500. The movement of the pusher 2 controls whether the first conductive portion 1a and the second conductive portion 2a are in contact, and the movement of the pusher 2 is driven by the threaded fastener 300. Therefore, the adjustment device of this embodiment of the present invention constitutes a self-control device, in which the height of the movement of the threaded fastener 300 inversely controls whether the tightening tool 500 is activated, thereby enabling the threaded fastener 300 to be quickly and accurately assembled to the pre-installed position with the mounting portion 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 portion to be installed 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 in the first position, the pusher 2 is abutted on the to-be-assembled part 201 under the driving of the elastic member 3, and the pusher 2 is abutted on the threaded fastener 300 at the same time, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation.

[0065] As shown, the pusher 2 is in the first position, the pusher 2 is abutted on the to-be-assembled part 201 under the driving of the elastic member 3, and the pusher 2 is abutted on the threaded fastener 300 at the same time, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation. Figure 3 As shown, the pusher 2 is in the intermediate position between the first position and the second position, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation. The threaded fastener 300 is driven by the tightening tool 500 to move in the first direction X from the first matching port 1111 to the second matching port 1112. The pusher 2 is also driven by the threaded fastener 300 to move in the first direction X from the first matching port 1111 to the second matching port 1112.

[0066] As shown, the pusher 2 is in the first position, the pusher 2 is abutted on the to-be-assembled part 201 under the driving of the elastic member 3, and the pusher 2 is abutted on the threaded fastener 300 at the same time, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation. 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, the threaded fastener 300 is relative to the to-be-assembled part 201, and the threaded fastener 300 is assembled to the to-be-assembled part 201 to the preset position.

[0067] As shown, the pusher 2 is in the first position, the pusher 2 is abutted on the to-be-assembled part 201 under the driving of the elastic member 3, and the pusher 2 is abutted on the threaded fastener 300 at the same time, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation. Figure 5 As shown, the pusher 2 is in the third position, at this time, the threaded fastener 300 has been assembled to the to-be-assembled part 201 to the preset position, the pusher 2 is driven from the second position to the third position by external force, and the movement of the pusher 2 from the second position to the third position has no effect on the tightening tool 500.

[0068] As shown, the pusher 2 is in the first position, the pusher 2 is abutted on the to-be-assembled part 201 under the driving of the elastic member 3, and the pusher 2 is abutted on the threaded fastener 300 at the same time, at this time, the first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is in operation. Figure 4 As shown, the first conductive part 1a and the second conductive part 2a are disconnected, the tightening tool 500 is controlled to stop working, the threaded fastener 300 is relative to the to-be-assembled part 201, and the threaded fastener 300 is driven to protrude from the to-be-assembled part 201 by the height h and stops. By adjusting the tool 100, the threaded fastener 300 can be quickly and accurately assembled to the position protruding from the to-be-assembled part 201 by the height h. 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, the threaded fastener 300 is relative to the to-be-assembled part 201, and the threaded fastener 300 is driven to protrude from the to-be-assembled part 201 by the height h and stops. By adjusting the tool 100, the threaded fastener 300 can be quickly and accurately assembled to the position protruding from the to-be-assembled part 201 by the height h.

[0069] As shown, the first conductive part 1a and the second conductive part 2a are disconnected, the tightening tool 500 is controlled to stop working, the threaded fastener 300 is relative to the to-be-assembled part 201, and the threaded fastener 300 is driven to protrude from the to-be-assembled part 201 by the height h and stops. By adjusting the tool 100, the threaded fastener 300 can be quickly and accurately assembled to the position protruding from the to-be-assembled part 201 by the height h. Figure 3 Figure 4 As shown, the first conductive part 1a and the second conductive part 2a are disconnected, the tightening tool 500 is controlled to stop working, the threaded fastener 300 is relative to the to-be-assembled part 201, and the threaded fastener 300 is driven to protrude from the to-be-assembled part 201 by the height h and stops. By adjusting the tool 100, the threaded fastener 300 can be quickly and accurately assembled to the position protruding from the to-be-assembled part 201 by the height h. Figure 3 ​When the pusher 2 is in the position shown in the figure, the adjusting tool 100 is assembled with the to-be-assembled part 201, and the pusher 2 is stopped against the threaded fastener 300, and the pusher 2 starts to work from the intermediate 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 assembled to the pre-assembly position of the to-be-assembled part 201. Figure 3 When the pusher 2 is in the position shown in the figure, Figure 4 When the pusher 2 is in the position shown in the figure.

[0070] It is worth mentioning that the height of the threaded fastener 300 assembled to the to-be-assembled part 201 is determined by the size of the first conductive part 1a in the first direction X, and 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 is stationary relative to the to-be-assembled part 201. Therefore, the height of the threaded fastener 300 assembled to the to-be-assembled part 201 can be adjusted by adjusting the size of the first conductive part 1a in the first direction X, and the adjusting work of the embodiment of the present application can select the first conductive part 1a with different sizes according to actual needs, and the application range of the adjusting tool 100 is improved.

[0071] The adjusting tool 100 of the threaded fastener according to the embodiment of the present application controls whether the tightening tool 500 is turned on by whether the second conductive part 2a of the pusher 2 and the first conductive part 1a of the cooperating seat 1 are conductive, and reversely controls whether the tightening tool 500 works by the moving height of the threaded fastener 300, so that the threaded fastener 300 can be quickly and accurately assembled to the pre-assembly position of the to-be-assembled part 201.

[0072] In some embodiments of the present application, as shown in the figure, Figure 2 The first conductive part 1a and the tightening tool 500 are connected through the first wire 401, and the second conductive part 2a and the tightening tool 500 are connected through the second wire 402, and 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 application, as shown in the figure, Figure 1 The cooperating seat 1 comprises a base 11 and a positioning piece 12, as shown in the figure, Figure 6 The cooperating cavity 111, the first cooperating opening 1111 and the second cooperating opening 1112 are formed on the base 11, the positioning piece 12 is connected to the base 11, and the positioning piece 12 is arranged on the side of the base 11 provided with the second cooperating opening 1112, as shown in the figure, Figure 7 The positioning piece 12 is provided with a positioning opening 121 corresponding to the second cooperating opening 1112. A part of the first conductive part 1a is arranged on the inner circumferential surface of the positioning opening 121, and a part is arranged on the inner circumferential surface of the second cooperating opening 1112.

[0074] The base 11 is used to cooperate with the to-be-assembled part 201, and the to-be-assembled part 201 extends into the cooperating cavity 111 of the base 11, so that the cooperation stability of the cooperating base 1 and the to-be-assembled part 201 can be improved.

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

[0076] Part of the first conductive part 1a is arranged on the inner circumferential surface of the positioning opening 121, and part of the first conductive part 1a is arranged on the inner circumferential surface of the second cooperating opening 1112. The first conductive part 1a and the second conductive part 2a can be in contact when the pushing member 2 slides in the base 11, and the first conductive part 1a and the second conductive part 2a can also be in contact when the pushing member 2 slides in the positioning sheet 12.

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

[0078] The height of the threaded fastener 300 assembled to the to-be-assembled part 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 started, 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 is stationary relative to the to-be-assembled part 201. Therefore, the height of the threaded fastener 300 assembled to the to-be-assembled part 201 can be adjusted by adjusting the size of the first conductive part 1a in the first direction X.

[0079] When the positioning sheet 12 is not assembled to the base 11, the pushing member 2 moves to the position 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 is stationary relative to the to-be-assembled part 201, and the height of the threaded fastener 300 protruding from the to-be-assembled part 201 is only controlled by the first conductive part 1a on the base 11.

[0080] When the positioning sheet 12 is assembled to the base 11, the pushing member 2 moves to the position where the second conductive part 2a and the first conductive part 1a of the positioning sheet 12 are just disconnected, the tightening tool 500 stops working, the threaded fastener 300 is stationary relative to the to-be-assembled part 201, and the height of the threaded fastener 300 protruding from the to-be-assembled part 201 is controlled by the first conductive part 1a on the base 11 and the first conductive part 1a on the positioning sheet 12.

[0081] As Figure 1As shown, the positioning piece 12 is arranged on one side of the base 11 provided with the second matching port 1112, so that when the positioning piece 12 is assembled to the base 11, the threaded fastener 300 can be controlled to protrude from the to-be-assembled part 201 in the direction of the first direction X closer to the second matching port 1112.

[0082] In some embodiments of the present application, the positioning piece 12 is at least two, and the thicknesses of the at least two positioning pieces 12 are equal or different.

[0083] By arranging multiple positioning pieces 12, different numbers or sizes of positioning pieces 12 can be selected to be assembled to the base 11 according to actual needs, so that the threaded fastener 300 can be assembled to different preset positions, improving the application range of the adjusting tool 100.

[0084] Specifically, when it is needed to assemble the threaded fastener 300 to a position higher than the to-be-assembled part 201, the number of the positioning pieces 12 assembled to the base 11 is increased, or the positioning pieces 12 with a larger size are assembled; when it is needed to assemble the threaded fastener 300 to a position lower than the to-be-assembled part 201, the number of the positioning pieces 12 assembled to the base 11 is reduced, or the positioning pieces 12 with a smaller size are assembled.

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

[0086] When the to-be-assembled part 201 is placed in the matching cavity 111, and the end surface of the to-be-assembled part 201 abuts against the inner wall surface of the matching cavity 111, the size h of the first conductive part 1a is the distance between the end of the first conductive part 1a in the first direction X and the to-be-assembled part 201.

[0087] The first conductive part 1a and the second conductive part 2a are in contact, and the tightening tool 500 is working. The tightening tool 500 drives the threaded fastener 300 to rotate into the to-be-assembled part 201, and drives the threaded fastener 300 to move in the first direction X from the first matching port 1111 to the second matching port 1112, at this time the adjusting tool 100 can quickly and accurately assemble the threaded fastener 300 to a position protruding from the to-be-assembled part 201 by a height of h.

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

[0089] When the positioning piece 12 is three, and includes a first positioning piece, a second positioning piece, and a third positioning piece, the inner circumferential surface of the first positioning piece in the first direction X has a size of h2a, the inner circumferential surface of the second positioning piece in the first direction X has a size of h2b, the inner circumferential surface of the third positioning piece in the first direction X has a size of h2c, and h2a+h2b+h2c=h2 is satisfied.

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

[0091] In some embodiments of the present application, the base 11 and the positioning piece 12 are both conductive, and the inner circumferential surface of the positioning port 121 and the inner circumferential surface of the second matching port 1112 are both conductive.

[0092] By setting the base 11 and the positioning piece 12 as conductive, compared with setting only at least part of the inner circumferential surface of the matching cavity 111 as conductive, the manufacturing cost can be reduced, the integrity of the base 11 and the positioning piece can be improved, and the structural reliability can be improved.

[0093] In some embodiments of the present application, as shown in Figure 1 The adjusting tool 100 further includes a guide seat 4, the guide seat 4 is installed on the matching seat 1, and the guide seat 4 is an insulating member. As shown in Figure 8 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 port 1112 as shown, the guide hole 41 is arranged to extend along the first direction X. As shown in Figure 9 A part of the pushing member 2 is a guide column 21, which is matched in Figure 8 The guide hole 41 as shown, the assembly effect is as shown in Figure 1

[0094] The guide seat 4 is installed on the matching seat 1, the guide seat 4 is stationary relative to the matching seat 1, and at least part of the pushing member 2 is slidingly matched in the guide hole 41 of the guide seat 4. The guide seat 4 plays a guiding role on the pushing member 2, guides the pushing member 2 to move stably along the first direction X, reduces the shaking of the pushing member 2, improves the movement stability of the pushing member 2, and thus improves the working reliability of the adjusting work.

[0095] The guide seat 4 is an insulating member, which can avoid short-circuit discharge caused by contact between the pushing member 2 and the guide seat 4, and improve the working safety of the adjusting work.

[0096] In some embodiments of the present application, as shown in​Figure 9 The pushing member 2 further comprises an abutting column 22 connected to one end of the guide column 21 facing the matching cavity 111, and the outer circumferential surface of the abutting column 22 constitutes Figure 2 the second conductive part 2a.

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

[0098] The guide seat 4 can also function as a limiting part, as Figure 9 shown, the cross-sectional dimension of the abutting column 22 is larger than that of the guide column 21, and the abutting column 22 cannot enter the guide hole 41. Figure 8 Therefore, as Figure 1 shown, the guide seat 4 limits the movement of the pushing member 2 in the first direction X from the first matching port 1111 to the second matching port 1112, and when the pushing member 2 is in the third position and the pushing member 2 is completely separated from the matching seat 1, the pushing member 2 is also limited by the guide seat 4, avoiding the pushing member 2 from being pulled out of the adjusting tool 100, and improving the working reliability of the adjusting work.

[0099] In some embodiments of the present application, as Figure 1 shown, the adjusting tool 100 further comprises 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 slidingly connected to the guide column 6, and one end of the pushing member 2 is installed on the fixed plate 5.

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

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

[0102] In some embodiments of the present application, the guide column 6 is two, and the two guide columns 6 sandwich the pushing member 2, which can further improve the stability of the movement of the pushing member 2.

[0103] In some embodiments of the present application, 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 fixed plate 5 and the other end is connected to the matching seat 1. As Figure 11 shown, the spring 3a is a cylindrical spring and is sleeved on the guide column 6.

[0104] The guide column 6 not only guides the movement of the pusher 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 deform only in the first direction X, so that the deformation deviation of the elastic member 3 can be reduced, and the working stability of the adjusting work is improved.

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

[0106] In some embodiments of the present application, as shown in Figure 10 The fixed plate 5 is provided with a fixed port 51, the fixed port 51 is provided through along the first direction X, and the fixed port 51 forms a socket 511 on one side of the fixed plate 5. Figure 9 As shown in Figure 10 The fixed port 51 is detachably assembled in the fixed port 51.

[0107] The cross-sectional size of the neck section 23 is smaller than the cross-sectional size of the guide column 21, and the neck section 23 and the fixed port 51 are matched to connect the pusher 2 and the fixed plate 5, so that the fixed plate 5 and the pusher 2 move together.

[0108] The fixed port 51 extends to the socket 511 through the edge of the fixed plate 5 on the side facing the fixed plate 5, the neck section 23 can be assembled into the fixed hole through the socket 511, and can be disassembled from the fixed hole through the socket 511, and the socket 511 facilitates the disassembly of the pusher 2 and the fixed plate 5.

[0109] In some embodiments of the present application, as shown in

[0110] Further, the pusher 2 and the fixed plate 5 are integrally formed, which can further improve the connection stability of the pusher 2 and the fixed plate 5, and also improve the structural reliability of the pusher 2 and the fixed plate 5.

[0111] In some embodiments of the present application, as shown in Figure 1 The matching seat 1 is provided with an opening 112, and the opening 112 is located on the side surface of the matching seat 1 perpendicular to the surface where the first matching port 1111 is located. That is, the opening 112 is located on one side of the matching seat 1 in the second direction Y, and the second direction Y is perpendicular to the first direction X.

[0112] The to-be-mounted portion 201 is mounted into the fitting 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 be moved along a direction perpendicular to the to-be-mounted portion 201.

[0113] In some embodiments of the present application, as shown in Figure 1 and Figure 6 The opening 112 is formed on the base 11.

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

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

[0116] The threaded fastener 300 can be a conductor, and the end of the pushing piece 2 and the threaded fastener 300 for abutting against each other is provided with an insulating layer, which can avoid the pushing piece 2 discharging to the threaded fastener 300, thereby improving the work safety of the adjustment work.

[0117] In some embodiments of the present application, an insulating rubber sheet is attached to the end of the pushing piece for abutting against the threaded fastener 300.

[0118] In some embodiments of the present application, as shown in Figure 9 The pushing piece 2 is a rotary body.

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

[0120] In some embodiments of the present application, the pushing piece 2 is a conductor. Compared with only setting at least part of the outer circumferential surface of the pushing piece 2 as a conductor, the pushing piece 2 as a whole conductor can reduce the manufacturing cost and improve the integrity and structural reliability of the pushing piece 2.

[0121] When the pushing piece 2 is a conductor as a whole, the pushing piece 2 as a whole can constitute the second conductive portion 2a. Of course, in other embodiments, the pushing piece 2 can also be set as an insulator, and then a section of wire is arranged on the pushing piece 2 as the second conductive portion 2a.

[0122] In some embodiments of the present application, as shown in Figure 12 and Figure 13As shown, the adjusting work is used to adjust the height of the positioning bolt 300a of the four-bar linkage 200 of the vehicle, and the height of the positioning bolt 300a has a greater influence on the Z-direction cooperation of the front cover and the fender. In order to ensure the Z-direction cooperation of the front cover and the fender, the positioning bolt 300a is required to be adjusted to the required height by the adjusting work.

[0123] In the related art, the method for adjusting the positioning bolt is to adjust the height of the positioning bolt and then measure the height of the positioning bolt. If it is unqualified, the height is continuously adjusted, and after the adjustment is completed, detection is performed again. The above steps are repeated until the height of the positioning bolt meets the target requirement.

[0124] The adjusting tool 100 of the embodiment of the present application can quickly adjust the positioning bolt 300a of the four-bar linkage 200 and quickly and accurately adjust the positioning bolt 300a to the required height.

[0125] The working process of the adjusting tool 100 of the embodiment of the present application is described below with reference to the accompanying drawings. The tightening tool 500 is an electric gun.

[0126] First, the height of the positioning bolt 300a is adjusted to be lower than the required height, and the adjusting tool 100 is assembled to the to-be-assembled part 201, that is, the adjusting tool is assembled to the four-bar linkage 200, and the upper surface of the cooperation cavity 111 close to the second cooperation port 1112 is attached to the to-be-assembled part 201.

[0127] The pushing piece 2 contacts the positioning bolt 300a under the elastic force of the elastic piece 3. At this time, the pushing piece 2 contacts the cooperation seat 1, and the pushing piece 2, the cooperation seat 1 and the electric gun form a closed circuit. The electric gun is operated from below the positioning bolt 300a protruding from the to-be-assembled part 201 to tighten the positioning bolt 300a.

[0128] During the tightening process, the height of the positioning bolt 300a is increased, and the positioning bolt 300a pushes the pushing piece 2 to move upward. When the pushing piece 2 is pushed to be not in contact with the cooperation seat 1, the electric gun is disconnected, and the electric gun stops running. At this time, the height of the positioning bolt 300a is h, h = h1 + h2.
