Description

Technical Field

[0001] This application relates to the field of screwdriver technology, and more particularly to a T-shaped screwdriver. Background Technology

[0002] The installation, commissioning, and maintenance of electrical equipment are crucial for ensuring the safe and stable operation of power systems. During these operations, especially live-line work, operators must strictly wear insulated gloves that meet safety standards to prevent electric shock. However, these insulated gloves are typically made of thick, stiff material, severely reducing hand dexterity and tactile feedback.

[0003] Currently, most screwdrivers on the market have the function of replacing the cutting head. However, the cutting head structure of existing screwdrivers is relatively small, which makes it difficult for operators wearing insulated gloves to replace the cutting head, thus affecting the operator's use of the screwdriver. Utility Model Content

[0004] This application provides a T-shaped screwdriver to improve the ease of changing the screwdriver tip, thereby improving the ease of use of the screwdriver.

[0005] To achieve the above objectives, the main technical solutions adopted in this application include: This application provides a T-shaped screwdriver, including a screwdriver body, a replacement block, a locking structure, and a screwdriver head. Along the extending direction of the screwdriver body, the screwdriver body has a mounting cavity located at one end and having an opening. The replacement block is installed in the mounting cavity through the opening, and at least a portion of the replacement block extends out of the mounting cavity through the opening. Along the extending direction of the screwdriver body, the replacement block has a degree of freedom of movement relative to the mounting cavity. An insertion hole is formed at the end of the replacement block opposite to the screwdriver body. The locking structure is installed on the replacement block, and at least a portion of the locking structure is inserted into the locking hole to lock the replacement block and the screwdriver body together. The screwdriver head is detachably installed in the insertion hole, and at least a portion of the screwdriver head extends out of the insertion hole.

[0006] As one implementation method, the snap-fit ​​structure is 2 to 3 cm away from the end of the replacement block along the extension direction of the screwdriver body.

[0007] Furthermore, the screwdriver body has multiple locking holes, which are arranged flat along the extension direction of the screwdriver body and are respectively connected to the mounting cavity; the locking structure is at least partially inserted into the locking holes to lock the replacement block and the screwdriver body.

[0008] Furthermore, the snap-fit ​​structure includes a limiting post, which is mounted on the replacement block and has a degree of freedom of movement relative to the screwdriver body, so as to insert the limiting post into the snap-fit ​​hole at different positions.

[0009] Furthermore, the snap-fit ​​structure also includes a first spring, which abuts against the limiting post and the replacement block respectively, and the first spring applies a first spring force to the limiting post toward the snap-fit ​​hole.

[0010] Furthermore, the replacement block includes a base and an end cap. A base hole is formed in the base, and the axis of the base hole is parallel to the axis of the snap-fit ​​hole. The end cap is located on one side of the base, and a through hole is formed in the end cap. The through hole communicates with the base hole to form a mounting hole, and the limiting post is installed in the mounting hole.

[0011] Furthermore, a countersunk hole is formed on the end cap; a screw hole is formed on the base, the screw hole and the countersunk hole are arranged coaxially and connected by screws.

[0012] Furthermore, the snap-fit ​​hole includes an interconnected insertion section and a bevel section, with the bevel section located at the end of the snap-fit ​​hole facing the replacement block.

[0013] Furthermore, the screwdriver body includes a main body and a handle. Along the extending direction of the screwdriver body, the mounting cavity is located at one end of the main body, and the handle is connected to the end of the main body away from the mounting cavity. The extending direction of the main body is perpendicular to the extending direction of the handle.

[0014] Furthermore, the T-shaped screwdriver also includes a second spring, which abuts against both the replacement block and the screwdriver body, and provides a second spring force to the replacement block toward the opening.

[0015] Furthermore, the T-shaped screwdriver also includes a magnetic block, which is mounted on the socket.

[0016] By mounting different screwdriver bits on different replacement blocks, screwdriver bits can be changed whenever a different shape or size of screwdriver bit is needed. This makes it easier for operators wearing insulated gloves to change screwdriver bits, thereby improving the ease of use of T-shaped screwdrivers. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figure 1 and Figure 2 As shown, as one implementation, this application discloses a T-shaped screwdriver, including a screwdriver body 1, a replacement block 2, a snap-fit ​​structure 3, and a screwdriver head 4. The screwdriver body 1 is the main structure of the T-shaped screwdriver. The operator applies a rotational force to the screwdriver head 4 through the screwdriver body 1. The replacement block 2 is used to install the screwdriver head 4 and to transition the screwdriver head 4 to the screwdriver body 1. The replacement block 2 provides an operating area for replacing the screwdriver head 4, so that the operator wearing insulated gloves can replace the screwdriver head, thereby improving the ease of use of the T-shaped screwdriver. The snap-fit ​​structure 3 is used to snap the replacement block 2 onto the screwdriver body 1 to ensure the installation stability of the replacement block 2.

[0025] Specifically, along the extending direction of the screwdriver body 1, the screwdriver body 1 has a mounting cavity 101 and a snap-fit ​​hole 102. The mounting cavity 101 is located at one end of the screwdriver body 1 and has an opening 1011. The snap-fit ​​hole 102 communicates with the mounting cavity 101.

[0026] The replacement block 2 is installed in the mounting cavity 101, and at least a portion of the replacement block 2 extends out of the mounting cavity 101 through the opening 1011. The end of the replacement block 2 opposite to the screwdriver body 1 has a socket 201.

[0027] Along the extending direction of the screwdriver body 1, the replacement block 2 has the degree of freedom to move relative to the mounting cavity 101. By moving the replacement block 2 relative to the mounting cavity 101, the replacement block 2 can be moved out of the mounting cavity 101, thereby facilitating the installation of different replacement blocks 2 onto the screwdriver body 1.

[0028] The snap-fit ​​structure 3 is installed on the replacement block 2, and the snap-fit ​​structure 3 is at least partially inserted into the snap-fit ​​hole 102, thereby locking the replacement block 2 and the screwdriver body 1 through the snap-fit ​​structure 3, ensuring the installation stability of the replacement block 2 and the screwdriver body 1.

[0029] The screwdriver head 4 is detachably installed in the socket 201, and at least part of the screwdriver head 4 extends outside the socket 201. Different models of screwdriver heads 4 can be installed on the replacement block 2 as needed, so as to meet different needs when using T-shaped screwdrivers.

[0030] It should be noted that the screwdriver bit 4 is a common screwdriver bit on the market, and before the operator performs installation, maintenance or other operations, the screwdriver bit 4 needs to be installed on the replacement block 2 so that the screwdriver bit 4 can be replaced by replacing the replacement block 2 during operation.

[0031] To more clearly describe the technical solution of this application, the following are defined: Figure 1 The upward and downward directions are shown. The extension direction of the screwdriver body 1 is... Figure 1 The vertical direction within the screwdriver body 1. It should be noted that the direction along the extension of the screwdriver body 1 refers to the direction the T-shaped screwdriver faces when used with the screw.

[0032] As one implementation, along the extension direction of the screwdriver body 1, the dimension of the snap-fit ​​structure 3 away from the end of the replacement block 2 is 2 to 3 cm, that is, when the snap-fit ​​structure 3 is pressed, the length dimension of the pressing surface of the snap-fit ​​structure 3 is 2 to 3 cm.

[0033] Similarly, the width of the pressing surface of the snap-fit ​​structure 3 is also 2 to 3 cm.

[0034] Optionally, the shape of the snap-fit ​​structure 3 facing away from the end of the replacement block 2 is circular or polygonal, and the diameter or length and width dimensions of its end face are both 2-3 cm.

[0035] By ensuring that the snap-fit ​​structure 3 has a sufficiently large pressing surface, it is easy for operators wearing insulated gloves to press the snap-fit ​​structure 3, thereby facilitating the replacement of the replacement block 2.

[0036] like Figure 2 and Figure 3 As shown, as one implementation method, the snap-fit ​​structure 3 includes a limiting post 301, which is installed on the replacement block 2 and has a degree of freedom of movement relative to the screwdriver body 1, so as to insert the limiting post 301 into the snap-fit ​​hole 102 at different positions.

[0037] Specifically, under normal conditions, the end of the limiting post 301 facing away from the replacement block 2 is at least partially inserted into the snap-fit ​​hole 102, thereby ensuring that the limiting post 301 can stably lock the screwdriver body 1 and the replacement block 2.

[0038] When it is necessary to remove the replacement block 2 from the screwdriver body 1, press the limiting post 301 to separate the limiting post 301 from the snap-fit ​​hole 102, so that the replacement block 2 can be separated from the screwdriver body 1.

[0039] As one implementation, the snap-fit ​​structure 3 also includes a first spring 302, which abuts against the limiting post 301 and the replacement block 2 respectively, and the first spring 302 applies a first spring force to the limiting post 301 toward the snap-fit ​​hole 102.

[0040] The first spring 302 ensures that the limiting post 301 is normally inserted into the snap-fit ​​hole 102.

[0041] like Figure 2 and Figure 3 As shown, in one implementation, the replacement block 2 has mounting holes for mounting the limit post 301 and the first spring 302.

[0042] Specifically, the replacement block 2 includes a base 202 and an end cap 203, with the end cap 203 mounted on one side of the base 202.

[0043] A base hole 2021 is formed in the base 202. The axis of the base hole 2021 is parallel to the axis of the snap-fit ​​hole 102. A through hole 2031 is formed in the end cover 203. The through hole 2031 is coaxially arranged with the base hole 2021 and the through hole 2031 communicates with the base hole 2021 to form a mounting hole.

[0044] One end of the limiting post 301 is installed in the base hole 2021, and the other end of the limiting post 301 extends to the outside of the replacement block 2 through the through hole 2031.

[0045] like Figure 4As shown, in one implementation, the inner diameter of the base hole 2021 is larger than the inner diameter of the through hole 2031. Meanwhile, the limiting post 301 includes a first segment 3011 and a second segment 3012 connected to each other. The diameter of the first segment 3011 is smaller than the diameter of the second segment 3012. The end of the first segment 3011 facing away from the second segment 3012 extends to the outside of the replacement block 2 through the through hole 2031. The diameter of the second segment 3012 is larger than the inner diameter of the through hole 2031, thereby locking the second segment 3012 into the base hole 2021 and preventing the limiting post 301 from separating from the replacement block 2 under the action of the first spring force.

[0046] As one implementation, a countersunk hole 2032 is formed on the end cap 203; a screw hole 2022 is formed on the base 202. The screw hole 2022 and the countersunk hole 2032 are arranged coaxially, and the screw hole 2022 and the countersunk hole 2032 are connected by screws. By setting the countersunk hole 2032, the screws used to install the base 202 and the end cap 203 are prevented from protruding from the end cap 203, thereby ensuring that the replacement block 2 can slide stably in the mounting cavity 101 and improving the convenience of replacing the replacement block 2.

[0047] like Figure 4 As shown, in one implementation, the snap-fit ​​hole 102 includes an interlocking insertion section 1021 and a slope section 1022 connected to each other, with the slope section 1022 located at the end of the insertion insertion section 1021 facing the replacement block 2.

[0048] Specifically, the slope section 1022 has a tapered hole structure to ensure that the limiting post 301 can be stably separated from the snap-fit ​​hole 102, thereby improving the ease of separation between the replacement block 2 and the screwdriver body 1.

[0049] like Figure 1 As shown, in one implementation, the screwdriver body 1 includes a main body 103 and a handle 104. The main body 103 is arranged along the extension direction of the screwdriver body 1, and the extension direction of the main body 103 is perpendicular to the extension direction of the handle 104, so that the screwdriver body 1 has a T-shaped structure.

[0050] The T-shaped screwdriver body 1 facilitates operation by personnel wearing insulated gloves, further improving the ease of use of the T-shaped screwdriver.

[0051] Specifically, the mounting cavity 101 is located at one end of the main body 103, and the handle 104 is connected to the end of the main body 103 away from the mounting cavity 101.

[0052] As one implementation, the T-shaped screwdriver also includes a second spring 5, which abuts against the replacement block 2 and the screwdriver body 1 respectively, and the second spring 5 provides a second spring force to the replacement block 2 toward the opening 1011.

[0053] When the top of the limiting post 301 is pressed to the slope section 1022, the replacement block 2 can be ejected from the mounting cavity 101 under the action of the second spring force, thereby improving the ease of disassembling the replacement block 2.

[0054] like Figure 2 As shown, in one implementation, a spring hole 105 is also formed in the screwdriver body 1. The spring hole 105 is connected to the end of the mounting cavity 101 away from the opening 1011, and the spring hole 105 communicates with the mounting cavity 101. The end of the second spring 5 away from the replacement block 2 is installed in the spring hole 105.

[0055] In one implementation, the second spring 5 is engaged with the spring hole 105, or the end of the second spring 5 away from the replacement block 2 is fixed on the end face of the spring hole 105 to prevent the second spring 5 from sliding out of the spring hole 105 when the replacement block 2 is removed from the mounting cavity 101.

[0056] like Figure 1 and Figure 2 As shown, as one implementation method, the screwdriver body 1 has multiple locking holes 102, which are arranged along the extension direction of the screwdriver body 1. By locking the limiting post 301 into the locking holes 102 at different positions, the overall length of the T-shaped screwdriver can be changed, thereby meeting the requirements of different working conditions for the length of the T-shaped screwdriver.

[0057] As one implementation method, the T-shaped screwdriver also includes a magnetic block 6, which is installed in the socket 201. The screwdriver head 4 is attracted to the socket 201 by the magnetic block 6, ensuring the installation stability of the screwdriver head 4.

[0058] The usage of this T-shaped screwdriver is as follows.

[0059] Before starting the work, install the required screwdriver bits 4 on different replacement blocks 2, and place the assembled replacement blocks 2 and screwdriver bodies 1 in the toolbox.

[0060] During operation, different models of replacement blocks 2 are installed on the screwdriver body 1 as needed. When the screwdriver head 4 needs to be replaced, the limiting post 301 is pressed, causing the limiting post 301 to retract mostly into the mounting hole. Under the action of the second spring force, the replacement block 2 pops out of the mounting cavity 101.

[0061] In addition, the limiting post 301 can be inserted into the snap-fit ​​hole 102 at different positions as needed, thereby changing the overall length of the T-shaped screwdriver and meeting the length requirements of the T-shaped screwdriver under different working conditions.

[0062] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.

[0063] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended claims.
