[0018] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0019] To better understand the above-mentioned objectives, features, and advantages of the embodiments of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the features in the embodiments of this application can be combined with each other.

[0020] The following description sets forth numerous specific details to provide a thorough understanding of the embodiments of this utility model. The described embodiments are only a portion, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of the embodiments of this utility model.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which embodiments of this invention pertain. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention.

[0022] In product assembly processes, such as assembling the casing and cover of a smartphone, thin, cylindrical inserts are typically used to securely connect the casing and cover. Because these inserts are delicate and small, they are inconvenient to handle manually. The assembly process using these inserts involves: the cylindrical insert has a groove on its outer circumference; an O-ring is placed around the insert, allowing it to be received and engaged within the groove (at this point, the outer diameter of the O-ring is slightly larger than the outer diameter of the insert). Then, the insert with the O-ring is passed through a guide hole on the cover and into a fixing hole in the casing. The bottom of the guide hole has the same diameter as the fixing hole in the casing, but the outer diameter of the O-ring is slightly larger. The insert, along with the O-ring, needs to be pressed vertically into the fixing hole to achieve the connection between the casing and cover. Because manual operation makes it difficult to maintain the vertical insertion of the insert, the O-ring is easily damaged during pressing, increasing manufacturing costs. Therefore, an auxiliary tool needs to be developed to ensure precise vertical installation of the insert.

[0023] Based on this, this application provides a clamping fixture 1000, please refer to [link / reference]. Figure 1The clamping fixture 1000 includes a handle assembly 100, a clamping assembly 200, and a pressing assembly 300. The handle assembly 100 includes a first handle member 10 and a second handle member 20 disposed opposite to each other. The first handle member 10 has a first end 10a and a second end 10b opposite to each other, and the second handle member 20 has a third end 20a and a fourth end 20b opposite to each other. The first end 10a and the third end 20a are disposed opposite to each other and are capable of moving towards or away from each other. The second end 10b and the fourth end 20b are disposed opposite to each other and are fixedly connected. The clamping assembly 200 is mounted on the first end 10a and the third end 20a. The clamping assembly 200 opens when the first end 10a and the third end 20a move away from each other and closes when the first end 10a and the third end 20a move towards each other. The clamping assembly 200 is used to clamp a workpiece. The pressing component 300 is installed at the second end 10b or the fourth end 20b. The pressing component 300 is used to press the workpiece to insert it vertically into the hole. This clamping fixture 1000 has the functions of clamping and pressing the workpiece, which helps to clamp small workpieces and help to press small workpieces and their materials vertically into the hole. This makes it less likely to tilt during the pressing process, effectively ensuring the accuracy of vertical pressing and reducing the risk of damage to the workpiece and its materials due to non-vertical pressing.

[0024] In this embodiment, the first handle component 10 and the second handle component 20 can be made of flexible metal or plastic, which can deform to a certain extent under the action of external force, so that the first end 10a and the third end 20a can move towards each other or away from each other under the action of external force or when the external force is removed.

[0025] In some embodiments, the first handle component 10 includes a first mounting portion 11, a first handle portion 12, and a first fixing portion 13 connected in sequence. The first mounting portion 11 is located at a first end 10a, and the first fixing portion 13 is located at a second end 10b. The second handle component 20 includes a second mounting portion 21, a second handle portion 22, and a second fixing portion 23 connected in sequence. The second mounting portion 21 is located at a third end 20a, and the second fixing portion 23 is located at a fourth end 20b. The first fixing portion 13 and the second fixing portion 23 are fixedly connected. The first mounting portion 11 has a through groove 11a extending through the first mounting portion 11. The second mounting portion 21 passes through the through groove 11a and protrudes from the surface of the first mounting portion 11 facing away from the second handle portion 22. An elastic space 30 is formed between the first handle portion 12 and the second handle portion 22. The elastic space 30 contracts or expands with the opposing or opposing movements of the first handle portion 12 and the second handle portion 22. When the first handle portion 12 and the second handle portion 22 are pressed simultaneously, they move towards each other, causing the first mounting portion 11 and the second mounting portion 21 to move away from each other. Therefore, the clamping assembly 200 opens during this back-to-back movement of the first mounting portion 11 and the second mounting portion 21. At this time, the workpiece can be placed inside the clamping assembly 200. When the first handle portion 12 and the second handle portion 22 are released simultaneously, they move away from each other, causing the first mounting portion 11 and the second mounting portion 21 to move towards each other. Therefore, the clamping assembly 200 closes during this back-to-back movement of the first mounting portion 11 and the second mounting portion 21. At this time, the workpiece is clamped inside the clamping assembly 200. This process achieves the clamping effect of the clamping fixture 1000 on the workpiece. Subsequently, the movable clamping fixture 1000 feeds the workpiece into the hole to be installed. Furthermore, compared to traditional clamping tools that require continuous pressure to maintain workpiece clamping after clamping, the clamping fixture 1000 of this application opens the clamping assembly 200 when force is applied and clamps the workpiece when the force is removed. Therefore, once the workpiece is clamped, there is no need for manual force to be continuously applied to the handle assembly 100 to clamp and move the workpiece, which helps save manpower and improves the convenience of clamping small workpieces.

[0026] In some embodiments, the clamping assembly 200 includes a first clamping piece 210 and a second clamping piece 220. The first clamping piece 210 is detachably fixed to the first mounting portion 11, and the second clamping piece 220 is detachably fixed to the second mounting portion 21. The first clamping piece 210 and the second clamping piece 220 can move towards or away from each other under the action of the handle assembly 100, so that the clamping assembly 200 opens or closes. The first clamping piece 210 and the second clamping piece 220 can move towards or away from each other under the action of the first handle portion 12 and the second handle portion 22, respectively, thereby realizing the opening and closing of the clamping assembly 200. The first clamping piece 210 and the second clamping piece 220 are detachably fixed to the first mounting portion 11 and the second mounting portion 21, respectively, to facilitate the replacement of the first clamping piece 210 and the second clamping piece 220.

[0027] In this embodiment, the first clamp 210 is fixed to the end of the first mounting portion 11 away from the first handle portion 12, and the second clamp 220 is fixed to the end of the second mounting portion 21 away from the second handle portion 22, which helps to make the opening and closing of the clamping assembly 200 less obstructed by the handle assembly 100.

[0028] In some implementation methods, please refer to the following: Figure 2 The first clamping piece 210 includes a first clamping portion 211 located outside the first mounting portion 11, and the first clamping portion 211 has a first slot 211a penetrating through the first clamping portion 211. The second clamping piece 220 includes a second clamping portion 221 located outside the second mounting portion 21, and the second clamping portion 221 has a second slot 221a penetrating through the second clamping portion 221. The first slot 211a and the second slot 221a are positioned opposite each other, and the first slot 211a and the second slot 221a form a clamping space 230 for accommodating a workpiece. The first slot 211a and the second slot 221a are arranged opposite each other to provide space for clamping the workpiece.

[0029] In some embodiments, the first clamping piece 210 further includes a first connecting portion 212, which is connected to the first clamping portion 211 and is fixed to the first mounting portion 11. The surface of the first connecting portion 212 facing away from the first mounting portion 11 and the surface of the first clamping portion 211 facing away from the second clamping portion 221 are stepped, which helps to make the lower surface of the first clamping portion 211 coplanar with the lower surface of the end of the first mounting portion 11, and facilitates the closing of the first clamping piece 210 and the second clamping piece 220.

[0030] In some embodiments, the second clamping piece 220 further includes a second connecting portion 222, which is connected to the second clamping portion 221 and is fixed to the second mounting portion 21. The surface of the second connecting portion 222 facing away from the second mounting portion 21 and the surface of the second clamping portion 221 facing away from the first clamping portion 211 are stepped, which helps to make the upper surface of the second clamping portion 221 coplanar with the upper surface of the end of the second mounting portion 21, and facilitates the closing of the first clamping piece 210 and the second clamping piece 220.

[0031] In some embodiments, the clamping fixture 1000 further includes an elastic reset assembly 400. The elastic reset assembly 400 is located within the elastic space 30 and is connected to the first handle portion 12 and the second handle portion 22. The elastic reset assembly 400 is used to reset the first handle member 10 and the second handle member 20.

[0032] In some embodiments, the elastic reset assembly 400 includes a first fixing member 410, a second fixing member 420, and an elastic member 430. The first fixing member 410 is connected to the first handle portion 12, and the second fixing member 420 is connected to the second handle portion 22. The first fixing member 410 and the second fixing member 420 are disposed opposite to each other. The first fixing member 410 has a first groove 410a that penetrates the surface of the first fixing member 410 away from the first handle portion 12. The second fixing member 420 has a second groove (not shown) that penetrates the surface of the second fixing member 420 away from the second handle portion 22. The two ends of the elastic member 430 are respectively fixed in the first groove 410a and the second groove, and the elastic member 430 abuts against the first fixing member 410 and the second fixing member 420.

[0033] In some embodiments, the pressing assembly 300 includes a pressing head 310, which is fixed to the second end 10b or the fourth end 20b. The pressing head 310 is columnar, for example, it can be a circular column, a square column, etc. The pressing head 310 is used to vertically press the workpiece into the hole.

[0034] In some embodiments, the pressing assembly 300 further includes a connector 320, which is fixed to the first fixing part 13 or the second fixing part 23, and the pressing head 310 is fixed to the end of the connector 320 away from the clamping assembly 200. The connector 320 serves to fix the pressing head 310 to the handle assembly 100.

[0035] In this embodiment, the connector 320 is provided with a positioning hole 320a penetrating its two opposing surfaces. The pressure head 310 is fixed in the positioning hole 320a and protrudes vertically from the surface of the connector 320 away from the handle assembly 100. The positioning hole 320a helps the pressure head 310 to be vertically mounted on the connector 320 and helps to keep the workpiece entering at an angle perpendicular to the hole when pressing the workpiece with the pressure head 310.
