Description

Technical Field

[0001] The present invention relates to the technical field of electrician tools, and in particular to an electrician tool. Background Art

[0002] Electrician tools are indispensable tools in life and work, and screwdrivers are the most commonly used. The most popular ones on the market are screwdrivers with replaceable screwdriver bars. Their advantages are that they can be replaced with different specifications of the bar, and the bar is relatively slender, which is suitable for operation in narrow spaces. However, their disadvantages are that they are inconvenient to operate and require users to constantly loosen and tighten their palms to rotate the handle. A screwdriver with a ratchet set can solve the above problem. You only need to hold the handle and rotate it back and forth continuously to quickly tighten or loosen the parts.

[0003] However, currently, the handle on the ratchet set is usually fixedly installed, and the screwdriver with the ratchet set itself cannot be replaced with a ratchet set of other specifications. In addition, due to the structural difference between the screwdriver bar and the ratchet set, the ratchet set cannot be applied to a screwdriver with a replaceable screwdriver bar. In other words, the existing ratchet set cannot be replaced and installed on a screwdriver with a replaceable screwdriver bar, and such a screwdriver is not very versatile and has relatively low applicability.

[0036] Embodiment 1

[0037] See also Figure 1-8 An electrician's tool comprises a handle 1, a plurality of replacement parts 2 and a locking mechanism 3. The locking mechanism 3 is arranged on the handle 1. Any replacement part 2 can be detachably arranged on the handle 1 through the locking mechanism 3.

[0038] See also Figure 1 and 2 The handle 1 includes a handle body 11 and a first end cover 12. A first installation cavity 111 is provided at one end of the handle body 11. The first end cover 12 is installed on the end of the handle body 11 close to the first installation cavity 111 and closes the first installation cavity 111. An opening 112 is provided on the side of the handle body 11 corresponding to the first installation cavity 111; a limit position 1111 is relatively provided on the side wall of the first installation cavity 111, and the limit position 1111 is a groove; the first end cover 12 is fixed to the end of the handle body 11 by ultrasonic welding. In addition, an avoidance cavity 113 is also provided in the handle body 11, and the avoidance cavity 113 is connected with the first installation cavity 111 to avoid the end of the replacement part 2. A connecting port 121 is also provided on the first end cover 12 for the replacement part 2 to pass through.

[0039] See also Figure 3 The multiple replacement parts 2 include ratchet sets 21 of different specifications, single-head screwdriver rods 22 of different specifications, and double-head screwdriver rods 23 of different specifications. Each replacement part 2 is provided with a locking section 24, and a locking position 241 is provided on the locking section 24. The locking position 241 cooperates with the locking mechanism 3 to relatively fix the single replacement part 2 to the locking mechanism 3. Among them, the locking position 241 is a groove.

[0040] Further, see Figure 3 For the replacement part 2 which is a single-head screwdriver rod 22 / double-head screw rod, a limiting protrusion 25 is provided on the locking section 24 of the single-head screwdriver rod 22 / double-head screw rod, and the limiting protrusion 25 cannot pass through the connecting opening 121, so as to prevent the single-head screwdriver rod 22 / double-head screw rod from excessively extending into the handle body 11.

[0041] Further, see Figure 3 and 4 For the replacement part 2 being a ratchet assembly 21, a rotating end cap 26 can also be provided for separate use to increase the diversity of the combination. A mounting head 212 is provided at the end of the locking section 24 of the ratchet assembly 21, and the rotating end cap 26 is mounted on the mounting head 212, and the rotating end cap 26 can rotate on the mounting head 212.

[0042] Preferably, the locking sections 24 of each replacement part 2 are rectangular, and locking positions 241 are provided on opposite sides of the locking section 24, so that blind installation can be achieved. Moreover, the avoidance cavity 113 and the connecting port 121 are both compatible with the locking section 24. When the handle 1 is rotated, the contact surface between the locking section 24 and the avoidance cavity 113 and the connecting port 121 is larger, the mutual force is increased, and there is no slippage and idling phenomenon, so that the replacement part 2 can better rotate with the handle 1, thereby increasing the torque.

[0043] See also Figure 1 and Figure 5-7 The locking mechanism 3 includes a locking member 31 and an elastic member 32. The locking member 31 is movably disposed in the first installation cavity 111. One end of the elastic member 32 abuts against the locking member 31, and the other end of the elastic member 32 abuts against the side wall of the first installation cavity 111. The acting direction of the elastic member 32 is parallel to the moving direction of the locking member 31. In this embodiment, a spring is used as the elastic member 32.

[0044] Specifically, the locking member 31 includes a first locking member 311 and a second locking member 312. The first locking member 311 and the second locking member 312 are arranged opposite to each other and both are U-shaped. The locking member 31 is split into two independent parts so as to be able to be quickly and easily installed on the handle 1.

[0045] The first locking member 311 includes a first acting portion 3111 and a first actuating portion 3112, and the first actuating portion 3112 is disposed oppositely at two ends of the first acting portion 3111. The second locking member 312 includes a second acting portion 3121 and a second actuating portion 3122, and the second actuating portion 3122 is disposed oppositely at two ends of the second acting portion 3121. The first acting portion 3111 and the second acting portion 3121 are disposed oppositely, and the first actuating portion 3112 and the second actuating portion 3122 are in one-to-one contact with each other.

[0046] Furthermore, the first action portion 3111 is installed on the opening 112 but cannot pass through the opening 112. A locking portion 31211 is provided on the inner side of the second action portion 3121, and the locking position 241 cooperates with the locking portion 31211; the locking portion 31211 is in a "concave" shape, and the locking position 241 fits the locking portion 31211. After the replacement part 2 and the handle 1 are installed, the contact area between the two can be increased, and the torque can be increased. A mounting column 31212 is provided on the outer side of the second action portion 3121, and one end of the elastic member 32 is sleeved on the mounting column 31212 and abuts against the outer side of the second action portion 3121, which is convenient for the installation of the elastic member 32 and limits the position of the elastic member 32. Preferably, an inclined surface is provided on the locking portion 31211, so that the replacement part 2 can push the locking portion 31211 along the inclined surface when installing.

[0047] Furthermore, a first limiting portion 31121 is provided on the outer side of the first actuating portion 3112, and a second limiting portion 31221 is provided on the outer side of the second actuating portion 3122. The first limiting portion 31121 and the second limiting portion 31221 are arranged in the limiting position 1111 on the same side, and the first limiting portion 31121 and the second limiting portion 31221 both move along the limiting position 1111, thereby limiting the moving direction and moving stroke of the locking member 31.

[0048] During the production process, the locking mechanism 3 is first correctly installed in the first installation cavity 111, and then the first end cover 12 is arranged on the handle body 11 to close the first installation cavity 111, and finally the first end cover 12 is fixed to the handle body 11 by ultrasonic welding.

[0049] In the absence of external force, the elastic force of the elastic member 32 continuously acts on the second acting portion 3121, and the second acting portion 3121 acts on the first acting portion 3111 through the second actuating portion 3122 and the first actuating portion 3112. At this time, the locking portion 31211 passes over the edge of the communication port 121 and keeps the first acting portion 3111 on the opening 112. When an external force is applied to the first acting portion 3111, the first acting portion 3111 pushes the second acting portion 3121 and compresses the elastic member 32 through the first actuating portion 3112 and the second actuating portion 3122, and the locking portion 31211 moves with the second acting portion 3121.

[0050] See also Figure 7 and 8 The following is an installation / disassembly description of the replacement part 2 for any ratchet assembly 21.

[0051] When installing the ratchet assembly 21, align the locking section 24 of the ratchet assembly 21 with the connecting opening 121 and then pass through the connecting opening 121 to go deep into the handle body 11; during this process, the locking section 24 will abut against the inclined surface of the locking portion 31211 and push the locking portion 31211, and there is no need to press the first acting portion 3111 to push the second acting portion 3121. The locking portion 31211 can also make a avoidance, so that the locking section 24 can pass between the first acting portion 3111 and the second acting portion 3121 and Going deeper into the avoidance cavity 113, when moving to the locking position 241 and facing the locking part 31211, the second acting part 3121 will move under the action of the elastic member 32, and the locking part 31211 moves to the locking position 241 along with the second acting part 3121. At this time, the ratchet group 21 cannot go deeper, and under the cooperation of the locking part 31211 and the locking position 241, the ratchet group 21 cannot be separated from the handle 1. The ratchet group 21 and the handle 1 are relatively fixed, and the installation is completed.

[0052] When disassembling the ratchet assembly 21, press the first acting portion 3111 to push the second acting portion 3121, and the locking portion 31211 moves with the second acting portion 3121, so that the locking portion 31211 is disengaged from the locking position 241. At this time, the locking section 24 of the ratchet assembly 21 is not hindered by the locking portion 31211, and the ratchet assembly 21 can be pulled off, thus completing the disassembly.

[0053] The installation or removal of other replacement parts 2 is the same as above.

[0054] In summary, tools of different specifications can be combined through the handle and different replacement parts, wherein the replacement parts include not only screwdriver rods of different specifications, but also ratchet sets of different specifications, which are suitable for different scenarios, realizing the function of providing different tool heads with a set of electrician tools. Any replacement part can be relatively fixed to the handle through a locking mechanism, which improves the applicability and versatility, and provides various combinations for daily use and carrying. In addition, the locking part surrounds the locking section of the replacement part, and the contact area between the handle and the locking section is large, so that the replacement part can rotate better with the handle, that is, the torque is increased.

When the handle 1 is used in conjunction with the double-headed screwdriver rod 23, it can be used as an electrical test pen.

[0057] The end of the handle body 11 away from the first installation cavity 111 is provided with a second installation cavity 114, and the second installation cavity 114 is connected with the avoidance cavity 113; the second end cover 13 is installed on the end of the handle body 11 close to the second installation cavity 114 and closes the second installation cavity 114. Among them, the second end cover 13 is fixed to the end of the handle body 11 by ultrasonic welding. A light-transmitting area 131 is provided on the second end cover 13, so the light-transmitting area 131 is made of a light-transmitting material. Preferably, the entire second end cover 13 is made of a light-transmitting material, so that a larger light-transmitting area 131 can be formed on the second end cover 13, so that light can be better transmitted.

[0058] A mounting seat 14 is provided in the second mounting cavity 114 . The mounting seat 14 is used to carry the contact electrical measurement module 4 and the induction electrical measurement module 5 . The mounting seat 14 includes a base 141 and a top seat 142 .

One end of the conductive rod body 231 is a cross blade, and the other end of the conductive rod body 231 is a slotted blade. The insulating sleeve 232 is sleeved on the conductive rod body 231, and the surface of the insulating sleeve 232 and the surface of the conductive rod body 231 are smoothly transitioned. When measuring electricity in a narrow space, the insulating sleeve 22 will not prevent the measuring rod from penetrating into the narrow space to contact the object to be measured.

[0060] The contact electrical measurement module 4 includes a conductive part 41, a resistor 42, a light-emitting part 43 and a metal part 44. The conductive part 41 is placed between the bottom of the second mounting cavity 114 and the bottom of the mounting seat 14; the resistor 42 is placed in the mounting seat 14; the light-emitting part 43 is placed on the top seat 142, and the light-emitting part 43 is opposite to the second end cover 13, and the light of the light-emitting part 43 is transmitted through the second end cover 13; the metal part 44 is installed on the end of the handle body 11 close to the second mounting cavity 114, and the metal part 44 is fixed there by the second end cover 13. The first end of the resistor 42 is electrically connected to the conductive part 41 through a conductive wire, the second end of the resistor 42 is electrically connected to the first end of the light-emitting part 43 through a conductive wire, and the second end of the light-emitting part 43 is electrically connected to the metal part 44 through a conductive wire. In this embodiment, a spring is used as the conductive part 41, and a neon bulb is used as the light-emitting part 43.

[0061] When the double-headed screwdriver rod 23 is installed on the handle 1, one end of the conductive rod 231 will abut against the conductive member 41. When the end of the conductive rod 231 contacts the object to be measured and the user contacts the metal member 44, the object to be measured, the conductive rod 231, the conductive member 41, the resistor 42, the light-emitting member 43, the metal member 44 and the human body will form a path. If the object to be measured is charged, the light-emitting member 43 will light up, and light will be transmitted from the second end cover 13. If the object to be measured is not charged, the light-emitting member 43 will not light up.

[0062] This embodiment adds an electrical testing module, and when the handle is combined with the double-headed screwdriver rod, it can be used as an electrical tester, thereby increasing the electrical testing function and further improving the practicality.

[0063] Embodiment 3

[0064] See also Figure 11-12 Compared with the second embodiment, this embodiment further provides an inductive electrical measurement module 5 , which is provided on the handle 1 .

[0065] The inductive power measuring module 5 is mounted on the side of the base 141, the first end of the inductive power measuring module 5 is electrically connected to the conductive member 41 through a conductive wire, and the second end of the inductive power measuring module 5 is electrically connected to the metal member 44 through a conductive wire.

An opening 115 is arranged at the handle 11 corresponding to the display module 51, and a light-transmitting decorative cover 15 is arranged on the opening 115.

[0066] Preferably, the inductive electrical measurement module 5 is electrically connected to the conductive component 41 through the resistor 42, that is, the first end of the inductive electrical measurement module 5 is electrically connected to the second end of the resistor through a conductive wire to ensure that the current flowing through the human body is small enough to ensure the personal safety of the user.

[0067] When the end of the conductive rod 231 of the double-headed screwdriver rod 23 approaches the object to be measured and the user touches the metal part 44, a path will be formed among the conductive rod 231, the conductive part 41, the resistor 42, the inductive electrical measurement module 5, the metal part 44 and the human body. If the object to be measured carries alternating current, the object to be measured generates an alternating magnetic field. When the conductive rod 231 approaches the object to be measured, it passes through the alternating magnetic field and moves to cut the magnetic lines of force. The conductive rod 231 generates a voltage and then drives the display module 51 of the inductive electrical measurement module 5 to display a charged mark. The user can observe the status of the display module 51 through the decorative cover 15. If the object to be measured is not charged, the display module 51 will not display a charged mark.

[0068] This embodiment adds an inductive electrical measurement module, that is, it has two electrical measurement modes: contact electrical measurement and inductive electrical measurement, giving users dual choices.
