Description

Technical Field

[0001] This utility model relates to the field of pliers technology, and in particular to a multifunctional pair of pliers. Background Technology

[0002] In a car folding key housing, the key cylinder needs to be pressed into the internal cavity of the key housing to form a stable interference fit. This is often achieved using reverse-push pliers, as shown in the attached diagram. Figure 6 As shown: When assembling, the user grips the pliers handles tightly, opens the two pliers heads, and inserts the pliers heads into the cavity inside the key case, so that the tips of the pliers heads abut against the end face of the key cylinder. While continuing to grip the pliers handles, the pliers heads open further, pushing the key cylinder into the key case until the interference fit between the key cylinder and the key case is in place. After the key cylinder assembly is completed, the user releases the pliers handles, the pliers heads come closer together, and the pliers heads are withdrawn from the cavity of the key case.

[0003] Pliers are typically used for two key operations: First, pressing the key core into the cavity of the key case and fixing them together with an interference fit. This step requires the pliers to be inserted into the cavity to push the key core. Second, adjusting the latches and seams between the two shells of the key case. This requires tools to be inserted into the narrow gap between the shells to pry or open them.

[0004] However, the pliers of existing conventional pliers have a one-piece metal structure, which can only achieve basic pushing and pushing operations. They cannot reach into the narrow gaps of the key shell to complete the prying / opening operation, and additional tools are required when working. At the same time, the working parts on both sides of the pliers are fixed structures, and the distance between the blades cannot be adjusted. Different models of car keys have different shell cavity sizes, and fixed-size pliers are difficult to adapt to various sizes of assembly spaces. Utility Model Content

[0005] In view of this, the purpose of this utility model is to propose a multi-functional pair of pliers that can be matched with different usage needs such as pushing or prying by installing push plates and pry plates on the sleeve body, so as to solve the above problems.

[0006] Based on the above objectives, this utility model provides the following technical solution: It includes two hinged clamp bodies, each clamp body having a clamp head at one end. Each clamp head is fitted with a sleeve. The sleeve has a push plate and a pry plate on its left and right sides of the same end face, respectively. The thickness of the pry plate is less than the thickness of the push plate, and the height of the pry plate is greater than the height of the push plate. A positioning post is provided on the clamp head; the positioning post is a regular square prism. A through groove adapted to the mounting post is provided on the sleeve. The positioning post and the through groove on the sleeve are interference-fitted to connect the sleeve to the clamp head. The sleeve can be rotated horizontally 180° and then installed on the clamp head to adjust the positions of the push plate and the pry plate.

[0007] The present invention is further configured such that: the pusher piece and the sleeve are integrally formed, and the sleeve is made of plastic.

[0008] The present invention is further configured such that: the skid is made of metal, and the lower end of the skid is injection molded and connected to the sleeve body.

[0009] The present invention is further configured such that a fitting groove is provided on the skid plate.

[0010] The present invention is further configured such that: a through groove adapted to the positioning post is provided on the sleeve body, and the through groove is provided through the sleeve body.

[0011] The present invention is further configured such that: a first hinge portion and a second hinge portion are respectively provided on the two clamp bodies, and a pivot for inserting the first hinge portion is provided on the second hinge portion, and the first hinge portion is rotatably mounted on the pivot.

[0012] The present invention is further configured such that: an expansion sleeve is installed inside the pivot, the outer wall of the expansion sleeve is fitted with the inner wall of the pivot, and the outer wall of the pivot is fitted with the inner wall of the first hinge portion.

[0013] The present invention is further configured such that: two clamp bodies are located on the side away from the clamp head and clamp handles are formed thereon, each clamp handle is provided with a protruding mounting post, and a spring is installed between the two clamp handles located at the mounting post.

[0014] The beneficial effects of this utility model are as follows: 1. Since the pusher and pry bar are provided on one end face of the sleeve, it can be used according to different usage needs: such as assembling a key core, the pusher is used to push the object, and the pry bar is used to insert into the gap of the key shell to separate the key shell, thus enriching the function of the pliers; 2. If the sleeve is worn, it can be removed and replaced. At the same time, the sleeve can be reversed and installed on the pliers head. Therefore, after the sleeve is separated from the pliers head, the sleeve rotates 180 degrees to fix the pliers head and the sleeve again, which can change the distance between the pry bar and pusher on the two sleeves, thereby satisfying the need to insert into gaps of different specifications.

[0027] like Figures 1-6As shown, a multi-functional pair of pliers includes two hinged plier bodies 1. Each plier body 1 has a plier head 11 at one end, and a sleeve 2 is mounted on each plier head 11. The sleeve 2 has a pusher 21 and a pry bar 22 on its left and right sides of the same end face, respectively. The thickness of the pry bar 22 is less than the thickness of the pusher 21, and the height of the pry bar 22 is greater than the height of the pusher 21. A positioning post 111, which is a regular square prism, is provided on the plier head 11. A through groove 23, adapted to the positioning post 111, is formed on the sleeve 2. The positioning post 111 and the through groove 23 on the sleeve 2 are press-fitted to connect the sleeve 2 and the plier head 11. The sleeve 2 can be rotated horizontally 180° and then mounted on the plier head 11 to adjust the positions of the pusher 21 and the pry bar 22. Figure 1-2 As shown, the sleeve 2 can be rotated 180° horizontally for reversal installation. After reversal, the distance between the pry plate 22 and the push plate 21 on the two sleeves 2 changes. 1. Since the push plate 21 and the pry plate 22 are provided on one end face of the sleeve 2, it can be used according to different usage requirements: such as assembling a key cylinder, the push plate 21 is used to push the object, and the pry plate 22 extends into the gap of the key shell to separate the key shell, thus enriching the function of the pliers; 2. If the sleeve 2 is worn, it can be removed and replaced. At the same time, the sleeve 2 can be reversed and installed on the plier head 11. Therefore, after the sleeve 2 is separated from the plier head 11, such as Figure 2 As shown, after the sleeve 2 rotates 180 degrees, the clamp head 11 is fixed to the sleeve 2 again, which changes the distance between the pry blades 22 and the push blades 21 on the two sleeves 2, thus allowing them to be inserted into gaps of different sizes; 3. The thinner pry blade 22 is easier to insert into narrow gaps or buckle gaps, and its height is greater than that of the push blade 21, so that the clamp head 11 will not interfere with the object when the pry blade 22 can be inserted into the gap. The push blade 21 is thicker and has sufficient strength when pushing objects such as key cores, so that it will not bend or break.

[0028] Furthermore, the pry bar 22 and push bar 21 of the pliers are not limited to car key assembly, but can also be applied to the following scenarios: insert the pry bar 22 into the gap of shells such as clams and oysters, and hold the pliers handle 12 to pry open the shells; it can also be used to pry open the back cover or screen of mobile phones and tablets; the push bar 21 can be used to push components such as ribbon cable interfaces and battery connectors.

[0029] Preferably, the pusher 21 and the sleeve 2 are integrally formed, and the sleeve 2 is made of plastic. Since the pusher 21 and the sleeve 2 are integrally formed, they can be mass-produced through injection molding. There is no assembly gap between the pusher 21 and the sleeve 2, so they will not loosen or detach. Furthermore, when the pusher 21 pushes the workpiece, it will not scratch the surface of the workpiece such as the key shell.

[0030] Preferably, the pry bar 22 is made of metal, and the lower end of the pry bar 22 is injection molded and connected to the sleeve 2. The metal pry bar 22 can withstand a large prying force and is not easy to bend or break, thereby realizing the prying open of the object. In addition, the metal is wear-resistant and is not easily worn after long-term use.

[0031] like Figure 4 As shown, the pry bar 22 has a fitting groove 221. The pry bar 22 is inserted into the sleeve 2 through the fitting groove 221 and is fitted and fixed with the sleeve 2. During the assembly process of the pry bar 22 and the sleeve 2, due to the presence of the fitting groove 221 on the pry bar 22, after the pry bar 22 is placed in the sleeve 2, the injection molding material is placed into the fitting groove 221 and solidified to form an interlock, thereby increasing the contact area between the sleeve 2 and the pry bar 22. The pry bar 22 can be stably fixed in the sleeve 2 and cannot be pulled out.

[0032] To further enhance the functionality of the pliers, the through slot 23 is provided through the sleeve 2, such as... Figure 2-3 As shown, when the pusher 21 and the pry bar 22 are located at the upper end of the sleeve 2 (upright installation), the pusher 21 and the pry bar 22 can be aligned with the space to be installed. At this time, the pusher 21 can push the key core by extending into the inner cavity of the key housing. However, because the length of the pusher 21 is limited, when it is necessary to push it into a deeper place, the pusher 21 is too short to reach the object to be pushed. After the sleeve 2 is inverted, the pliers 11 can be inserted into the cavity and contact the object through the other end of the sleeve 2 to push it.

[0033] In addition, the two clamp bodies 1 are respectively provided with a first hinge part 13 and a second hinge part 14. The second hinge part 14 is provided with a pivot 141 for inserting the first hinge part 13. The first hinge part 13 is rotatably mounted on the pivot 141. During assembly, the shaft hole of the first hinge part 13 is sleeved on the pivot 141 of the second hinge part 14, so that the first hinge part 13 can rotate relative to the second hinge part 14 with the pivot 141 as the rotation center. This structure is stable in rotation and easy to assemble. Moreover, the pivot 141 and the second hinge part 14 are integrally formed, avoiding the risk of the independent rotating shaft loosening or falling off.

[0034] However, during use, the force may cause the pivot 141 to deform, resulting in the two clamp bodies 1 being unable to be stably assembled together and becoming loose. A tightening sleeve 131 is installed inside the pivot 141. The outer wall of the tightening sleeve 131 fits against the inner wall of the pivot 141, and the outer wall of the pivot 141 fits against the inner wall of the first hinge part 13. The tightening sleeve 131 is installed inside the pivot 141. After tightening, it will completely eliminate the gap between the two, greatly improving the deformation resistance of the pivot 141, thereby improving the stability of the two clamp bodies 1 during use.

[0035] It is also worth noting that the second hinge part 14 is closed at one end of the pivot 141, which realizes the axial limitation after the expansion sleeve 131 is installed. At the same time, the two sides of the pivot 141 can fit with the inserts on both sides of the expansion sleeve 131 to realize the radial positioning of the expansion sleeve 131, so that it cannot rotate. Furthermore, since the pivot 141 is stretched open by the expansion sleeve 131 after the expansion sleeve 131 is installed, the elastic clamping force at the contact position with the expansion sleeve 131 will continue to act, keeping the pivot 141 in a stretched state and stably connected to the first hinge part 13, so that the expansion sleeve 131 will not loosen.

[0036] An expansion sleeve 131 is installed inside the pivot 141 to open the gap between the pivot 141 and the second hinge 14. After the expansion sleeve 131 is installed inside the pivot 141, it can open the gap between the pivot 141 and the second hinge 14 to eliminate the shaking between the two clamp bodies 1. And because there is no looseness at the hinge, the pushing / prying operation of the clamps can be carried out more stably.

[0037] Two clamp bodies 1 are located on the side opposite to the clamp head 11, forming clamp handles 12. Each clamp handle 12 has a protruding mounting post 121. A spring 122 is installed between the two clamp handles 12 and the mounting posts 121. Due to the presence of the spring 122, after the clamp handles 12 are released, the elasticity of the spring 122 drives the clamp body 1 to open automatically. At this time, the clamp head 11 will close, making it easy to remove the object from the inserted space when pushing it, thus providing convenience for the use of the clamps. The two ends of the spring 122 are respectively sleeved on the two mounting posts 121. The mounting posts 121 guide the extension and retraction of the spring 122, preventing bending or displacement during the compression of the spring 122. At the same time, the mounting posts 121 position the spring 122 during installation and deformation, preventing the spring 122 from falling off the clamp body 1 during use.
